Problem resuming from a screen switch off

will824 · 09-18-2011, 09:37 PM

Greetings everyone,

Some background on this issue

- I am running Linux (Gentoo distro) on a Dell System XPS L502X.
- This system has Nvidia optimus techonology and a Corei7 processor.
- I am using the Intel card in Xorg all the time and only use the Nvidia card when I need to run some games
- Intel and Nvidia drivers are the latest
- ACPI is enabled in the kernel

Now,the system is configured for energy saving in Xorg, meaning that after some minutes que screen will go black (no leds).

Then sometimes when moving the mouse or pressing a key to make the computer screen come to life again, the computer will display a white screen for 1 second that will flicker and afterwards the screen leds will light but it will remain black. All background activity is untouched and the computer does not freeze.

I can reproduce the problem by issuing the command:
$ xset -display :0 dpms force off

Then I if my screen fails then I will keep pressing up in the keyboard and enter to issue the keyboard again as I know the focus will be in the terminal. Doing this will randomly make the screen come back to life, sometimes at once, other times after 4 or 5 tries.

Does someone have the same issue as me?.
Can somebody help me solving this problem?

This is my system configuration:

Try your Hal settings. It seems hal is used for some of that stuff.

Hi,

I've the same problem on a Asus N55SF laptop (Intel HD and Nvidia GT555M with Optimus).
When the srceen is back, it's white, and leds become gradually black (like a cloud... the first time I thought it was the screensaver!)

I'm not really sure Hal is involved because I'm using Archlinux and it's not installed (I was thinking it was deprecated?).

I don't know where to report this bug!
I put a post on Archlinux forum: https://bbs.archlinux.org/viewtopic....05062#p1005062

This works well for me now. My last distribution update contained new kernel, graphic drivers and a lot of things, so I on't know what fixed it...

Linux doesn't want to wake up on my computer either. It just blacks out and stays that way. Especially when I close the lid.

business_kid · 11-22-2011, 02:59 AM

I only noticed the word optimus now. Some interesting stuff here
http://www.linuxquestions.org/questi...m-card-914705/

Apparently optimus needs (non existent) software support.
