Comment 9 for bug 300304

ok, I did a new test today

Clean Kubuntu 8.10 install from the alternate cd.

First start: When KDM starts, I can see the cursor nice & clear but other than that I'd say there's a sync problem or something. Since I'm able to see the cursor it's something else..?

I ran updates, installed ssh and restarted.

Login & startx to see that the same problem is still there: cursor is nice and clear but the rest is a mess..

Installed xserver-xorg-core-dbg libgl1-mesa-dri-dbg xserver-xorg-video-ati-dbg (actually these were installed: libgl1-mesa-dri-dbg xserver-xorg-core-dbg xserver-xorg-video-ati-dbg xserver-xorg-video-mach64-dbg xserver-xorg-video-r128-dbg xserver-xorg-video-radeon-dbg) and added this to xorg.conf:
Section "ServerFlags"
        Option "NoTrapSignals" "true"
EndSection
and tried to backtrace but since X doesnt' crash here (see problem #1 in the first message of the bug rep)

Then I install xorg-driver-fglrx (which installed dkms fakeroot fglrx-amdcccle fglrx-kernel-source patch xorg-driver-fglrx) to try the problem #2 (actually I think I have two separate problems here - maybe this should be split in two reports, someone please tell me?)

At this point I also removed KDM..

I tried to run sudo /etc/init.d/Xorg and it started but running the open drivers, I think (same symptons).

So I run sudo dpkg-reconfigure xserver-xorg (though AFAIK it doesnt change the driver in xorg.conf) and then (for some reason) I restarted the computer (maybe it's required to install the kernel modules or something..?)

And now, finally got it crashing:
