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 ;-) - -- Cheers, Carlos E. R.
