Description Andy Grover 2011-10-31 06:24:16 UTC

When the screen is turned off by the "Turn off after" setting in System Settings -> Screen, it does not get turned back on by user activity (e.g. keypress), like it should. This is also annoying because there's no disable (see bug 692037) so leaving the laptop on will eventually result in this behavior, if a user has stepped away.

Interestingly, suspending/resuming the laptop in this state turns the backlight back on, so at least that's something.

This is on a Lenovo Edge e220s laptop with

 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09).

this bug still shows up for me, with the updated package.

1) Set timeout to 1 minute
2) Wait until screen dims and backlight goes out
3) press keys. it still doesn't come back

Is it fixed on your e420s?

Comment 5 Lars Sjöström 2011-11-22 20:28:38 UTC

Yes that's exactly what I did and it works for me.
I have a fully updated F16 with latest kernel (3.1.1-2.fc16.x86_64)

That's really strange because I believe e220s and e420s is basically the same machine?

Comment 6 Lars Sjöström 2011-11-22 20:48:15 UTC

I think I spoke to quickly! tested once more and this time the backlight didnt come back. Looks like its not consistent. annoying! 

Back to square one!

Something else we can do to debug? 

Maybe a Tickless kernel thing? I will try the nohz=off boot options.

Comment 7 Andy Grover 2012-01-07 00:07:48 UTC

this is working ok for me now. Lars, how's it working for you?

Comment 8 Lars Sjöström 2012-01-09 09:17:12 UTC

Yes, now it working!

Comment 9 Andy Grover 2012-01-09 17:02:11 UTC

yay it works! closing.
