VT switching again

[LubosD]

Hello,

after about 20 VT switches between my desktop session and an OpenGL game, the screen first turned black and then the LCD turned off.

NVRM: Xid (0008:00): 13, 0000 01016100 0000008a 00000838 0006495a 00000010
NVRM: Xid (0009:00): 30,  L1 -> L0
NVRM: Xid (0008:00): 30,  L1 -> L0

So I killed both X sessions (everything remotely via SSH from this point) and did rmmod nvidia in hope that X would start again. I was wrong.

NVRM: loading NVIDIA UNIX x86_64 Kernel Module  1.0-9742  Tue Nov  7 09:45:02 PST 2006
NVRM: RmInitAdapter failed! (0x12:0x2b:1543)
NVRM: rm_init_adapter(0) failed
NVRM: RmInitAdapter failed! (0x12:0x2b:1543)
NVRM: rm_init_adapter(1) failed

And X error:

Reboot fixed the problem.
PLEASE, fix the VT switching once for ever. Two years ago it would kill the system instantly, now it just takes some more time...

This happened to me, too. I had to reboot computer, because LCD hasn't started again... Tried to switch VT's, but nothing happened
