what can bring this problem ??
kernel, Xorg, faulty graphics card?
during while init process, system is ok, splash screen works just fine, but when starting X (gdm), 7 of 8 times I see just horizontal black and white lines. keyboard stuck.
only buttons working - power and reset.
while input is stuck, background processes work ok - I can ssh into this pc..
the 8th (not really counted, just "something about 8th time
") time Xorg does not freeze and I can use it just fine.
checked log files..
diff Xorg.0.log Xorg.0.log.old
brings nothing. At first it showed only that mouse used is different (/dev/input/even4 vs /dev/input/even5), but last time it was the same...
Also, in some places (e.g. firefox render screen), my mouse pointer is "dirty" (using transparent m.p.)
I guess kernel does work - since bg process are not stuck.
graphics card or Xorg ?? also - this happens NOT every time.. just 7/8
Also, noticed, that if I run StarUml in wine, the Xorg freezes too (this time no horz lines - the last screen used is left). only this program (so far) brings this. And if I press reset (not power off and on again), the SAME screen is stuck instead of lines (after reboot)!!!
using ubuntu jaunty, kernel 2.6.28-11-generic, Xorg 1.6.0 with nv driver
