blank screen when returning from suspend on NB30

Postby frgenoud » 26/03/2012, 19:58

Hi Voria,

I have a strange one for you here. I had lots of trouble from the very beginning with the backlight on my NB30. Now running ubuntu 10.04 and everything was working fine with samsung-backlight (and wireless -- also had some trouble with that previously) until the update last week. I now get a blank screen when coming back from suspend with the lid shut on battery power (and the keyboard seems inactive, not only the screen). On the other hand, if I suspend manually without shutting the lid then the computer wakes up normally. The strange thing is I don't have any problem on AC power, the computer wakes up normally anyway.

As I didn't have this problem before the last update, is it possible to recover the previous version of the backlight driver? I suspect this can be the problem. Or maybe you want to try and fix it in the next version?

Best wishes

Francois

For some reason it seems to work again now. I had an update done yesterday after posting my problem, but nothing seemed directly related to the backlight, only some kernel stuff and a google chrome update as far as I remember. The behaviour of the backlight is really strange on this NB30...
