Hi Charl,

What you can do is turn off the visual effects, this might stop the glx/openGL stuff

System -> Preferences -> Appearance

Click on Visual Effect tab

Click on None

Wait a few seconds

Try the above, see if it works

Ok, so I'm still struggling a bit with the video card.  I went back to
Ubuntu since I like it better and it seems to run fine on this P4 even
with only 512K RAM.

A normal boot still hangs on the gdm login screen. To get into the
desktop I have to boot into the recovery console and the select the
failsafeX mode.  It then gives me the error:

AIGLX error: diopen /usr/lib/nouveau_vieux_dr.so failed...
AIGLX error: reverting to software rendering

I then select "Run Ubuntu in low graphics mode for for just on session"
and it works... amazingly at full resolution too!  (Not sure what they
then mean by low-graphics mode) From here on everything runs perfectly!

I have blacklisted the nouveau driver in /etc/modprobe.d/blacklist.conf
to prevent it from loading.  I also purged all nvidia packages.  It seems
somewhere the system still remembers that it want to run glx/openGL.

It used to be easy, you just edit the /etc/X11/xorg.conf file, but that
no longer exists.  None of the advice I found on Google seemed to be
relevant.

Anyone with ideas?

Regards
Charl
