ATI FGLRX and Logging Off

[Michael Bach (gmx)]

Same problem for me on an IBM Thinkpad T23 2647

I ran 6.10 with an automatically configured xorg.config with no 
problems. Even 3D stuff like Tremulous and ppracer were on decent speed 
with the standard savage driver. Yesterday I installed 7.04 and problems 
appeared. (The problems even persisted with using the xorg.conf from 6.10):

First:
> When I log in, I can do a shutdown and a restart from the GUI.  I can not do 
> an end session.  When clicking the button, kdm does not load and I get the

Exactly the same on my system.

Second:
running glxinfo brings the following:
[mike at miami][~]$  glxinfo
name of display: :0.0
libGL error: drmMap of framebuffer failed (Invalid argument)
libGL error: reverting to (slow) indirect rendering
display: :0  screen: 0
direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2

I googled for "libGL error: drmMap of framebuffer failed (Invalid 
argument)" and various results came up. Possible solutions range from 
dri kernel module recompile to creating symlinks of kernel objects or 
recompiling the graphics driver.

I have not started looking into any of these solutions. I hope that a 
working update to whatever the problem is becomes available soon.

A workaround I discovered:
I never liked the splashscreens (probably an old slackware heritage), so 
I configured my /boot/grub/menu.lst and removed the "quiet" 
kerneloption, changed to "nosplash" and use 1024*768 framebuffer 
"vga=791". As a result, my system boots very verbosely (that's actually 
one of the things I really like about Linux) and I eventually end up in 
kdm. When I log in, and then out, kdm does not reappear, but a login 
propmt shows up. When I login with my credentials, I can go back into 
KDE with startx.
This is just a workaround.

Having found a few solutions to problem, I dare a little to go through 
the kernel and/or graphics driver recompile lottery...
