black screen at start (if boot after a suspend)
Hi all,
I am having the following problem.
On a laptop, I sometimes let the system shut down due to low battery (I
suspect there is other triggers possible but II am sure of this one).
Then on next boot I will end up with a black screen with the undersocre
in the top left corner. System seems to be running ok tough I can not
even switch to a terminal. If I press the power button (configure to
shutdown the computer) I can reboot normally. If I hold it to do an
"Hard" shut down this problem will reappear on next boot.
I am use an HP laptop on jessie/sid with dual (muxed) gpu ati/intel. I
use a script to switch OFF the radeon agp at boot. (echo OFF >
/sys/kernel/debug/vga/switcheroo/switch)
Any clues ?
Regards,
Laurent
