libvga.config, svgalibrc - the svgalib configuration file
The svgalib configuration is usually located in /etc/vga/libvga.config
though one can reconfigure this location when recompiling svgalib.
In the configuration file, everything between a # and the end of the
line is ignored. Empty lines are also ignored. Since the driver you
will use may not know all config options here, unknown commands are
silently ignored. Please think of that when something does not work as
you expect. I know this is a nuisance because malformed configuration
statements do not cause errors. Multiple commands are allowed in one
line, and commands can exceed lines.
Actually, svgalib simply reads a list of whitespace separated tokens
from the file until it finds one it knows and it then assumes the
following tokens to be arguments of that command until one is
encountered which may not be an argument.
New style options are in general case insensitive whereas the old style
options are case sensitive. The old style options are included to allow
for old config files still being used. For completeness they are
documented in the OBSOLETE COMMANDS section. You should not use them
In addition, svgalib(7) parses the files ~/.svgalibrc and the file
given in the environment variable SVGALIB_CONFIG_FILE.
Finally, the contents of the environment variable SVGALIB_CONFIG are
parsed like the files before.
Configuration commands which control hardware settings that might cause
harm to your hardware are called privileged. By default the privileged
commands can only be used in the main configuration file
/etc/vga/libvga.config for safety (s.t. a non root user can not cause
any harm to your hardware by misconfiguring svgalib(7)).
Enable them in the other locations as well with the command
overrideenable in the main config file. BEWARE! This allows every
user to change the monitor and clocks (and other configs) and thus
damaging the hardware. I strongly discourage the use of overrideenable
except for debugging/testing purposes.
Please do not allow the vastness of options to confuse you. Generally
svgalib uses well chosen defaults and is able to autodetect everything.
Thus generally you don’t need to specify much. When installing svgalib
it provides a sample /etc/vga/libvga.config file which contains most of
the required configuration. Just edit it to your needs.
Generally you only need to use:
mouse To specify if you use anything else then a Microsoft compatible
mdev If the mouse device file is not /dev/input/mice which is the
actual mouse device file. You will usually need to use this
command if you want to use the SpaceTec Spaceball device (which
is not your usual mouse).
setRTS, clearRTS, leaveRTS, setDTR, clearDTR, and leaveDTR
if your mouse needs it to enter your desired mouse protocol.

GENERAL OPTIONS (HANDLED BY THE MAIN MODULE)
where mousetype is one of: Microsoft, MouseSystems, MMSeries,
Logitech, Busmouse, PS2, MouseMan, gpm, Spaceball, none,
IntelliMouse, or IMPS2. mousetype can also be a number (0 - 9)
for the keywords Microsoft - none.
gpm allows for (hopefully) peaceful interaction with gpm,
Spaceball enables support for the 6-axes Spacetec Spaceball
mouse (well, probably more like a trackball), IntelliMouse and
IMPS2 refer to the Microsoft IntelliMouse or Logitech MouseMan+,
where IntelliMouse is for serial port and IMPS2 for such a mouse
on the PS/2 port.
Note that it is not possible to specify the Microsoft
IntelliMouse or Logitech MouseMan+ by a number. This is due to
historical and compatibility reasons.
This command is only available if ALLOW_MOUSE_OVERRIDE was set
in Makefile.cfg when svgalib was compiled (which is the
If given, svgalib ignores any mouse type the program specifies
but uses the type configured with the mouse command.
For example, DOOM does not recognize MouseMan as a valid mouse
type and defaults the mouse type to MouseSystems. This command
allows to make svgalib ignore whatever DOOM specifies and use
Usually /dev/input/mice (the default) will be the mouse device.
However, esp. with the Spacetec Spaceball you may want to
specify a different device for svgalib(7) to use:
mdev /dev/ttyS0 # mouse is at /dev/ttyS0
Some multiprotocol mice use the state of RTS and DTR to find out which
protocol to enable:
setRTS set the RTS wire.
clear the RTS wire.
leave the RTS wire alone (default) (Wire is usually set)
setDTR set the DTR wire.
clear the DTR wire.
leave the DTR wire alone (default) (Wire is usually set)
For example my mouse can emulate Microsoft and MouseSystems. It needs
a low RTS to go into MouseSystems mode. Thus I use:
mouse MouseSystems clearRTS
Still I could just use mouse Microsoft and use the mouse with that
protocol.. But then only 2 buttons instead of 3 are supported (not that
I know many svgalib programs that uses more than 2 buttons.)
Other mice might need clearDTR as well or one set and clear. Try
Note: Having crtscts handshake enabled on the mouse tty may interfere
with this option. Do not do that.
Finally, a special goodie for wheel mice:
mouse_fake_kbd_event upscancode downscancode
sends a fake keyboard event to the program when the wheel on a
Microsoft IntelliMouse, Logitech MouseMan+, or similar wheel
mouse is turned.
The up and down scancodes are the scancodes of the keys to
simulate when the wheel is turned up and down, respectively.
The following can be specified for the scancodes: letters (A-Z),
numbers (0-9), function keys (F1-F12), or any of the following -
ESCAPE, MINUS, EQUAL, BACKSPACE, TAB, BRACKET_LEFT,
BRACKET_RIGHT, ENTER, LEFTCONTROL, SEMICOLON, APOSTROPHE, GRAVE,
LEFTSHIFT, BACKSLASH, COMMA, PERIOD, SLASH, RIGHTSHIFT,
KEYPADMULTIPLY, LEFTALT, SPACE, CAPSLOCK, NUMLOCK, SCROLLLOCK,
KEYPAD7, CURSORUPLEFT, KEYPAD8, CURSORUP, KEYPAD9,
CURSORUPRIGHT, KEYPADMINUS, KEYPAD4, CURSORLEFT, KEYPAD5,
KEYPAD6, CURSORRIGHT, KEYPADPLUS, KEYPAD1, CURSORDOWNLEFT,
KEYPAD2, CURSORDOWN, KEYPAD3, CURSORDOWNRIGHT, KEYPAD0,
KEYPADPERIOD, KEYPADCENTER, RIGHTCONTROL, CONTROL, KEYPADDIVIDE,
PRINTSCREEN, RIGHTALT, BREAK, BREAK_ALTERNATIVE, HOME,
CURSORBLOCKUP, PAGEUP, CURSORBLOCKLEFT, CURSORBLOCKRIGHT, END,
CURSORBLOCKDOWN, PAGEDOWN, INSERT.
Note that this option has no effect unless the IntelliMouse or
IMPS2 mouse type is used (see above). Also note that the
simulated keypresses are instantaneous, so they cannot be used
for functions that require a key to be held down for a certain
length of time.
This example simulates a press of the left bracket ([) when the
wheel is turned up and a press of the right bracket (]) when the
wheel is turned down (good for selecting items in Quake II):
mouse_fake_kbd_event BRACKET_LEFT BRACKET_RIGHT
Svgalib versions 1.3.0 and later use the following commands to control
the logarithmic mouse acceleration:
If given, force use of input parameters even if they seem
Set max delta BEFORE acceleration.
Set max delta AFTER acceleration.
Set acceleration threshold.
Set input variable for power mode.
Set acceleration factor.
Set the type of acceleration. The following strings are
0 or off
normal No acceleration while delta is less than
mouse_accel_thresh but multiplied by
mouse_accel_mult if more.
Originally done by Mike Chapman
power The acceleration factor is a power function of
delta until it reaches mouse_accel_mult After
that it’s a simple multiplication. Basically it’s
like the normal mode but the acceleration factor
grows as you move your mouse faster and faster,
not just turns in and out. If the acceleration
factor reaches mouse_accel_mult it turns into a
Threshold has the same meaning as in normal mode.
The one I use for *uaking... :)
It is calculated like this:
if (abs(dx) > 1) /* to prevent losing resolution
dx = (abs(dx) >=
mouse_accel_thresh ) ?
linear The acceleration factor grows linear with the
delta until it reaches mouse_accel_thresh. After
that it is a simple multiplication. (I know that
it can be done with setting mouse_accel_power to
1, but it was one minute to implement... and uses
no memory... and...)
It is calculated like this:
if (abs(dx) > 1)
dx = (abs(dx) >=
mouse_accel_thresh ) ?
(float)dx * abs(dx) *
The enhanced acceleration was done by 101 (Attila Lendvai)

If the parameter is off or on it will turn off/on the
respective mouse axis (requires a parameter, of course)
send a fake event that the mouse button is pressed or
released as given by the parameter (pressed or released)
Here are some examples:
This is one I use in *uake: it turns around, looks down a bit
and when the key is released it does the opposite, so it gets
back to the starting state. With this one and the help of a
rocket you can fly though the whole map :) (Scancode 28 is

<Right Ctrl> is kept pressed.
kbd_fake_mouse_event 97 down deltay off

This one is the same as if you were pressing the left mouse
button. (But if you move your mouse then the button state will
reset even if you keep <Right Ctrl> down...)

NOTE: This does only work when the keyboard is in raw keyboard
Yet another feature brought to you by 101 (Attila Lendvai)
This command disables generation of a SIGINT signal when <Ctrl-
C> is pressed.
This works regardless of ordinary or raw keyboard mode (albeit
the hot key might be different from <Ctrl-C> in the first case).
Note that this is a very dangerous option. Disabling SIGINT will
lock you in programs which can only by quit by <Ctrl-C>!
However, there were request for it for Quake playing.
Enables generation of SIGINT.
HorizSync min_kHz max_kHz
VertRefresh min_Hz max_Hz
specifies the range of frequencies acceptable to your monitor.
They obsolete the monitor settings below, and this shouldn’t be
used if HorizSync and VertRefresh are defined. Examples:
HorizSync 31.5 35.5
VertRefresh 50 70
where monitor_class is a digit 0 - 6 or the maximal horizontal
frequency in kHz. Examples:
monitor 0 # Max horizontal sync is 31.5 kHz
monitor 1 # Max horizontal sync is 35.1 kHz
monitor 2 # Max horizontal sync is 35.5 kHz
monitor 3 # Max horizontal sync is 37.9 kHz
monitor 4 # Max horizontal sync is 48.3 kHz
monitor 5 # Max horizontal sync is 56.0 kHz
monitor 6 # No restrictions.
For your convenience you may specify the max horizontal sync
explicitly. The correct class will the be chosen. You may use
floats consisting of digits and a decimal point for this too:
monitor 40.0 # equivalent to monitor 3
This command is privileged.
It is now possible to define modetimings for some cards (see the info
on your card in svgalib(7)). The syntax is:
modeline label pxcl HDsp HSS HSE HTot VDsp VSS VSE VTot flags
(ignored by svgalib) mainly there to be compatible with
XF86Config. I use the format "Width x Height @
Vert.Refresh", but that’s just personal taste...
the pixel clock in MHz
size of the visible area (horizontal/vertical)
Sync start (horizontal/vertical)
Sync end (horizontal/vertical)
Total width/height (end of back porch)
flags +hsync -hsync +vsync -vsync interlace interlaced
doublescan Sync polarity, interlace mode
Everything should be on one line. The values for the horizontal
timings must be multiples of eight.
These are preferred over the default timings (if monitor and chipset
can handle them). The format is identical to the one used by XFree86,
but the label following the modeline keyword is ignored by vgalib.
Here some examples:
modeline 640x480@100 43 640 664 824 848 480 483 490 504
modeline 800x600@73 50 800 856 976 1024 600 637 643 666
modeline 1024x768@75 85 1024 1048 1376 1400 768 771 780 806
IMPORTANT! Not all drivers, that is SVGA cards, use the values. Only
drivers using timing.c. As of this writing, drivers using this feature
are: Ark, Cirrus, Chips & Technologies, Et6000, S3.
The Mach32 driver provides a similar feature separately, you have to
use the define command described below.
ET4000 (and to some extent EGA) allow one to use a binary file created
by some utility. All other chipset driver use predefined timings that
are hardcoded in register dumps within the drivers. See
svgalib.et4000(7) for more information.
Usually svgalib does a good job autodetecting your hardware. However,
if auto detection fails (or you want to fall back to a simpler driver,
say VGA, as a bug work around), you may force detection of your chipset
where type is (currently) one of: VGA, ET4000, Cirrus, TVGA,
Oak, EGA, S3, ET3000, Mach32, GVGA6400, ARK, ATI, ALI, Mach64,
C&T, APM, NV3, ET6000, VESA, MX, PARADISE, and RAGE.
You can also specify a number in range 1 - 22 to specify the
type-th chipset type or 0 to enforce autodetection.
Warning, incorrect settings may damage your hardware. This
command is privileged.
chipset type param1 param2
use this form if the size of memory or an additional
configuration option is misdetected. For example:
chipset Mach32 0 2048
Note that always two integers have to be specified. Usually
(Mach32) the second parameter is the memory amount. Look at the
*_init function of the specific device driver sources or
information on that type of cards in svgalib(7).
Note that there is a more convenient command setuplinear for
enforcing specific memory-aperture configurations for Mach32
This command is privileged.
Specific options required for the EGA-driver.
Card is in monochrome emulation mode
Card is in color emulation mode
This command is privileged.
Some chipsets (e.g. S3 and ARK) allow specifying a RAMDAC type. If your
RAMDAC is not autodetected, you can try specifying it:
AT&T 20C490, 491, 492 (and compatibles)
IBM RGB524, 526, 528 (and compatibles)
BEWARE! The Mach32 driver features an own ramdac command (which is
usually not required). If you have a Mach32, see svgalib.mach32(7).
speed is a floating point number in MHz (like in Dacspeed40.0")
specifying the maximal allowable pixel clock of the Ramdac in
use. Currently this option is only supported by the S3 driver.
The Mach32 driver supports maxclock8, maxclock16, maxclock24,
and maxclock32 commands which have a similar effect.
Nevertheless, the Mach32 has a very good idea on the
capabilities of the Ramdac in use. The settings are more
intended to specify the VGA memory bandwidth.
Clocks list of clock values as floats or ints
Some chipsets need a list of dot clocks for optimum operation.
Some includes or supports a programmable clock chip. You’ll
need to specify them here.
Fixed clocks example: (The following is just an example, get the
values for your card from you X setup)
Clocks 25.175 28.3 40 70 50 75 36 44.9 0 118 77 31.5 110 65 72
BEWARE! The Clocks command for the Mach32 features only integer
clocks. Please round your clocks to the next integer data. The
Mach32 only uses these values to check monitor requirements and
to compare the quality of modes. The rounding errors are of no
importance there as the difference in the resulting monitor
timings is barely measurable. See the Mach32 section below.
Configure for a programmable clockchip. ICD2061A is the only
one supported right now.
Make sure it is impossible to regain root access after
vga_init(3) was called. (default)
For compatibility to pre 1.2.11, do not close a security hole
using saved uids.
Mach32: show messages while processing all info to build up a
quiet Turn verbose messages off (default).
Inhibit use of a linear mmaped frame buffer.
linear Allow (not enforce!) use of a linear mmaped frame buffer.
Allow privileged commands outside the main configuration file.
Common options currently used by Mach32 only
Options that may be useful for all drivers, but currently are only
supported by Mach32 (Please read svgalib.mach32(7) if you use one):
The maximum pixel clock to use for 16bpp modes. This is used by
Mach32 to find out which settings may be used for 16bpp modes.
the Mach32 default for this is 2000, thus it is effectively
switched off. maxclk must be an integer.
The maximum clock to use for 24bpp modes. (see above) Experience
showed that the Mach32 default 49 is good for my 2MB VRAM card.
The same for 32bpp modes (24bpp with one fill byte for faster
memory access (not fully implemented (esp. for Mach32) yet).
Mach32 default (good for my VRAM card) is 39.
Just for completeness the same for 8bpp modes (I doubt anyone
needs it), default is 2000 to disable this feature.
The maxclock commands are privileged.
clocks list of clocks
Sets the frequencies of the clocks the chips can generate.
Exactly 16 values have to be specified for mach32. Use 0 to
disable a specific clock.
Note that the mach32 can divide clocks by 2. Thus there are
actually 32 clocks And you can also use the divided clocks in a
define command. On contrary to Xfree96 or the clocks command
above only integers are allowed for Mach32. Simply round them to
the nearest integer.
This line is mandatory for Mach32. If it is not there it will be
auto detected and added at the beginning of the config file. The
program will then exit and when you start it next, everything
should be ok.
Common clock values for Mach32:
Clock chip 18811-0:
clocks 43 49 92 36 50 56 0 45
30 32 110 80 40 45 75 65
Clock chip 18811-1:
due to Xfree86 info valid for: Ultra pro ISA, Ultra pro
EISA, Ultra pro VLB(68800-3)
clocks 100 126 92 36 50 56 0 45
135 32 110 80 40 45 75 65
Clock chip 1881 (ICS2494):
due to Xfree86 info valid for: Ultra pro VLB (6880006)
clocks 18 22 25 28 36 44 50 56
30 32 37 39 40 0 75 65
In my own correspondence with ATI they say every Mach32 would
have a 18811-1, so it should be possible just to take the
18811-1 line. However I have now reports of third party cards
and motherboards with on board Mach32 chips, so be careful.
Please read svgalib.mach32(7) for additional info on clocks.
The clocks command is privileged.
Sometimes a mode cannot be realized with the logical linelength
= pixels in a row * bytes per pixel. (definitely true for Mach32
800x600). The default behavior of Mach32 is to adjust xbytes
(see vga_getmodeinfo(3)) in the info table appropriately.
This command enforces this default operation and adjusts xbytes
appropriately, thus overriding the standard svgalib mode. This
may yield to problems with ..umm.. not well designed
Don’t touch the standard mode but create an exact copy, a
dynamic mode, with the adjusted xbytes value. Expect noise at
some pixels in 800x600 for more than 256 colors on Mach32 when
not using the dynamic mode.
Same as above but delete the standard mode thus creating the non
conforming xbytes modes only as dynamic modes.
To enforce the standard linelength for non-conforming modes use
The linelength commands are not privileged.
In the following commands a mode is specified with horzXvertXcolors.
Valid settings for colors in the mach32 driver are: 256, 32K, 64K, 16M,
16M4. 16M4 is for the 16M colors with 32bpp modes. These are expected
to support slightly faster drawing.
Examples: 640x480x256, 1024x768x64K, etc...
inhibit mode1 [mode2 mode3...]
Switch the specified SVGA-Modes off. For example:
inhibit 800x600x32K 800x600x64K 800x600x16M
disallows the maybe toasted mach32 800x600 modes.
The inhibit command is not privileged.
setlinelength length mode1 [mode2 mode3...]
Force the logical line length (xbytes) in the given modes to
length pixels (not bytes!). See also variablelinelength,
strictlinelength, and duplicatelinelength above. For example:
setlinelength 800 800x600x32K 800x600x64K 800x600x16M
sets the linelength, and thus xbytes, for the 800x600 modes to
the equivalent of 800 pixels. For Mach32 this will give badly
designed applications an 800x600 with which they can cope.
However, the Mach32 will generate a noisy video signal in some
The setlinelength command is not privileged.
define mode1 [mode2 mode3...] clock horz_timing vert_timing flags
where clock is a clock in MHz (as an integer! Has to be known by
the driver. (one of the set clocks, or the exact half of one)).
Only clocks in a clocks command issued before the define can be
You may use :n to specify the n-thclock (n = 0 .. 31 for
horz_timing is four integers: hdisp h_sync_strt h_sync_wid
vert_timing has the same format but for vertical.
You may specify one or more flags out of: Interlace, +vsync,
-vsync, +hsync, or -hsync to select interlace mode and polarity
of sync signals. This format is almost the same Xfree uses, s.t.
you may use their mode table and the modegen spreadsheet package
for mode creation. You simple need to round the clock to the
next integer, add the resolution instead of the timing name for
Xfree and replace the modeline keyword with define. Here is a
1024x768x256 mode as example:
define 1024x768x256 80 1024 1024 1184 1312
768 768 772 791 +vsync -hsync
define 1024x768x256 1024x768x32K 1024x768x64K
:11 1024 1024 1184 1312 768 768 772 791
(yes any whitespace in a command is allowed, even a newline !)
Both commands define the same timings (if the 11-th clock is 80)
but the first explicitly specifies the polarity of sync signals
whereas the second declares that these timings are also to be
used for a 32K and 64K mode.
The define command is privileged.
There is one really dangerous option (except faking clocks). Please use
it only if you are sure what you are doing. Wrong setup will lead to
multiple components accessing your bus at once and thus to probable
setuplinear address size
Sets up a linear frame buffer at address of size size (both are
given in MB). If the values make sense (for example address
<16MB for ISA cards) the linear aperture is setup. Since the
Mach32-driver auto detects configured address itself, I strongly
discourage use of this command. However I was asked for it as
some PCI mach32-cards didn’t setup the linear aperture
Please ensure that the address range from address to address +
size (exclusively) is not used in your system. Obey that due to
memory remapping for example 16MB Ram may exceed the 16MB
Valid Mach32 values for size are 1 and 4 (only 4 in PCI
configurations), address + size have to be below 16MB for ISA,
4GB for multiplexed PCI, and 128MB else. Example: (my setup)
setuplinear 64 4
for a 4MB linear frame buffer at address 0x4000000.
It is also valid to specify setuplinear 0 0. This will actually
disable/de-configure any linear frame buffer. Useful to disable
mach32 aperture even if it is enabled in the EEPROM.
The setuplinear command is privileged.
blit subcommand1 subcommand2 ...
This is a command to control the Mach32 support for oldstyle
Valid subcommands are bit, fill, image, and hlinelist. They
enable support for the corresponding blit functions. Precede
them with no to turn them off (no space after no allowed). Use
memimage to emulate the image blit using a linearframebuffer,
which is usually much faster for Mach32. Use nomemimage to
never use this emulation. On the Mach32 this emulation can be
used in more resolutions than the actual imageblit accelerator
function. Again order is vital! (esp. for the *image commands).
As the Mach32 now has also new style vga_accel(3) support there
are now also the subcommands: settrans, setrop, fillbox,
screencopy, drawline, putimage, drawhlinelist, putbitmap,
screencopymono, setmode, polyline, polyhline, and polyfillmode.
Which are also supported with a leading no. They allow to
control support for the subfunctions of vga_accel(3). In
addition, memimage emulation applies to putimage as well.
blit image nomemimage
Use IO-style imageblt where possible. Don’t emulate it in
blit image memimage
Use emulated imageblt where possible.
blit memimage image
Use IO-style imageblt where possible, and the emulation
where possible in the remaining modes.
Disable support for imageblt.
Mach32 default is:
blit bit fill image hlinelist settrans setrop
fillbox screencopy drawline putimage
drawhlinelist putbitmap screencopymono
setmode polyline polyhline polyfillmode
The blit command is not privileged.
The Mach32 has also a few intermediate debug options for low level
timing adjust. They are:
There also options which are useful to support broken Mach32 cards or
third party hardware based on Mach32 which does not follow the ATI
specifications completely. For example:
For details about these options see svgalib.mach32(7). All of them are
Very old svgalib versions used a different style configuration file.
For compatibility, svgalib can still parse these old options. Generally
the options consist of one character (case sensitive) followed by a
number. Whitespace characters (space, tab, newline) can be used after
the characters m and M and the number.
The old svgalib versions actually allowed a new option character to
follow a number immediately. The current parser requires white space
after the numbers.
Of course, you should not use these cryptic forms anymore. The obsolete
