Title:
[Lenovo Thinkpad x201] blank display on after resume from suspend
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
same hardware as bug 830355:
this seems like a recent regression in Precise (maybe between kernel
-16 and -18):
after coming back from suspend, the internal laptop display is backlit
but blank. switching consoles, etc, doesn't help. it does reboot on
ctrl-alt-delay and there are blinks of wlan activity so I think it did
wake up.
