If you experience similar problem that is to be seen on the picture :
you should consider downloading my bugfix. It should be run once the X server is up and then refresh the screen.
Binary version is here fixw32p.gz (note it is gzipped)
It must also be executed when the resolution of the display changes (CTRL_ALT_+)(:-((
The application should look like this:
Installation procedure:
This bugfix must be SUID root, becouse of its direct access to the VGA's registers. It changes 1 bit in 1 register which has to do something with onboard memory timing.
I recommend you to download the source code:
source code for fixw32p.c
compile it with gcc: gcc fixw32p.c -o fixw32p
the compiled executable fixw32p put into
/usr/X11R6/bin/
and SUID root (do all of this stuff as superuser(root))
chmod 4555 fixw32p
For automatic execution of this bugfix add one line to the file
/var/X11R6/lib/xinit/xinitrc.fvwm if you are using FVWM.
Here's my script xinitrc:
#!/bin/sh
# $XConsortium: xinitrc.cpp,v 1.4 91/08/22 11:41:34 rws Exp $
userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/usr/X11R6/lib/X11/xinit/.Xresources
sysmodmap=/usr/X11R6/lib/X11/xinit/.Xmodmap
# merge in defaults and keymaps
if [ -f $sysresources ]; then
xrdb -merge $sysresources
fi
if [ -f $sysmodmap ]; then
xmodmap $sysmodmap
fi
if [ -f $userresources ]; then
xrdb -merge $userresources
fi
if [ -f $usermodmap ]; then
xmodmap $usermodmap
fi
# start some nice programs
fixw32p 1 0 1
xsetroot -solid SteelBlue
xload -hl red -nolabel -jumpscroll 1 -update 2 &
xsysinfo &
oclock &
fvwm
I've added the bugfix to my FVWM menu. It's on the first line, so whenewer I change resoulution, I just run it and then refresh the screen. It' pretty dumb and there may exist some more elegant solutions (automatic execution on res. change or even including it in the Xserver source).
If you want to have it in the system menu, just add it to /var/X11R6/lib/fvwm/system.fvwmrc (for fvwm users)
An example cut from system.fvwmrc:

And this is an example of it in action:
My bugfix is for rev_c PCB (VL-BUS, some program said rev_a). This is yet second release of the fix with parameters support. The source code contains information on how to setup it.
