Re: What part of X causes major display problems?

[darrell <ddupasedm@netscape.net>]

you are running an X display manager that automatically restarts the x 
server after it is taken down with alt-ctrl-backspace, so to solve this 
you have to kill the x display manager, then reconfigure x, then start 
the x display manager, you probably are using gdm (gnome display 
manager) but it is possible that your using xdm as well, so:

# 1. switch to console
alt+ctrl+f1

#2. determine your display manager

ps -ax

# find either gdm or xdm in the output of ps

#3. kill the display manager

killall gdm

#4. reconfigure your x server (  this can be done by trial and error, 
but take care,

#4.1 determine your video card

SuperProbe

# use conservitive settings when in doubt, xf86config is the program to use

xf86config

# also, i recommend killing gpm before running gdm or X again
# also, until you get a reasonable display, i recomment just starting X 
with the command X

killall gpm   # mouse util for console, mucks up x mice

X

# then once it looks good

alt+ctrl+backspace

gdm

#if you just installed woody, you may need to do a gdm config to select 
a window manager

X &
wmaker --display :0
gdmconfig

find a line that looks like

Xsession

#and make it look like:

Xsession wmaker


# all this said, if you asked 20 linux users we would all do it differently!
