[pkg-nvidia-devel] Bug#533163: Bug#533163: nvidia-glx: fails to start

[Jakub Lucký]

We can forget all that about kernel upgrades...

Now I realized (after some tesing), that problem is not in kernel upgrades,
but in rebooting and halt... When computer is powered off (like shutdown
-h)  and I boot it again, GDM fails to start, but when I reboot it (after
this problem), everything is OK...
