try booting with i915.powersave=0

It works, but the effect dies with hibernation. On restore, the display
dies after... dunno, more than one hour.

Huh, that's a bug, the "powersave" status has to be restored on resume...

I guess that the entire handling of that particular video chip is buggy.
Either the chip, the driver, or both. And maybe even the display itself.

I rebooted the machine, and after some hours I noticed the display did not respond. I confirm via ssh in syslog that the kernel line is correct:

2013-09-07T16:41:14.816102+02:00 AmonLanc kernel: [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.7.10-1.16-default root=UUID=c538c7a3-97ea-4eae-91fc-fdfea0fc1aca resume=/dev/disk/by-label/Swap showopts splash=verbose loglevel=3 console=tty1 vga=791 i915.powersave=0


So, it does not make effect, or not always.



It is a nuisance, but mostly I'm handling that laptop remotely, via ssh, so it is not a big-big deal.


Maybe if I need the display one day I'll try placing a dead weight in the shift key, after boot ;-)
