Computer doesn't wake from sleep mode
 

I have a laptop with Linux Slackware 14, KDE 4.8.5, kernel 3.9.0-rc6. When I close the lid and pull out the power cord, the machine goes into sleep mode. When I wake it, plugging the cord back in and opening the lid, the LEDs turn on, but the screen doesn't. The system responds via ssh. Maybe, it's Intel video driver?

Here is some additional info regarding my system:

Here's info about my video card:

Looking at the output in the log pm-suspend.log there is mention of an illegal instruction at line #48 of the 99video script. Here are the contents of that section of the script:

Then I thought, that it doesn't work, because I don't have the swap. I created it, using instructions here:

still, doesn't work. Any ideas?

this is not a solution but to have a little bit more details:

did you try restarting X-server? it may help since X uses its own video drivers

also, if there is any peripheral plugged in (USB stick, external display, mouse, etc.) unplug it before closing LED

How can I restart it, when the screen is black? I can give a command from the external machine only through ssh. Tried Crtl-Alt-F2 to switch to console, didn't help.

ok, I'll unplug the mouse. But I don't think it will help.

you can stop/restart X via ssh; also 3.9.0-rcX is quite recent kernel, try something more time proved

i've been using different Intel's cards with minor issues, it should work!

I removed nomodeset kernel param & now it works correctly. Thanks.
