Public bug reported:
Hi,
after installing the restricted modules and latest kernel (problem occured with
gutsy and feisty), I got some issues with my ATI-Chip (Mobility Radeon X300)
and X. (This problem occurs with an "old" config (which is bullet-proofed) and
even with a new config, created by fireglcontrol or ati-config))
After changing and restarting Xserver needs to be restarted.
- 1st scenario:
1 monitor (Laptop-LCD): everything works
- 2nd scenario:
dual-head (horizontal-display chosen) and 2nd monitor powered on: X hangs, you
can't kill X, you can't switch to console, everything you see is a black screen
on both TFTs. You can get out of this trap if you're either rebooting the
system (CTRL+ALT+DEL) or power-off this laptop.
- 3rd scenario:
Do, what you did in 2nd scenario again and after the "rescue-reboot" you need
to have switch your 2nd monitor on. This will also make your system freezing,
again.
--> Looks for me, like the system's going fscked up, when initializing a
2nd monitor...
