9 Post subject: Black screen appears randomly  PostPosted: May 22, 2008 - 10:15 AM

A black screen appeared after I worked with the console and synaptic and again when I had my external disk open, Gaim and iceweasel open.

The starts gets black with a fuzzy bar and colours on the upper side of the monitor and then it gets completely black.

I tried ctrl+alt+backspace and nothing happens.

This is a very serious thing. I had to shutdown my laptop twice.

Has anyone gone through this?

It's a known problem of new intel drivers: http://bugs.parsix.org/bugzilla/show_bug.cgi?id=126

Parsix is not the only distro affected. I recently updated intel drivers to 2.3.1, it's more stable than older 2.2.x based ones but still I face crashes sometimes. I'm still working to find a workaround.

Ok, thank you. This can be very inconvenient.

Thank you very much.

Please edit X.Org config file:
Code:
vim /etc/X11/xorg.conf

in the "Device" section, Add the following line:
Code:
Option          "DRI"                   "false"

And comment out the following lines:
Code:

#Option         "RenderAccel"           "1"
#Option         "XAANoOffscreenPixmaps" "true"
#Option         "AddARGBGLXVisuals"     "true"

This disables 3D capabilities but makes X more stable. Please test and report me the result. Thanks.

In Viola-TEST-2, those three lines are commented out, but not in TEST-1, I mentioned to be sure. In my case, adding
Code:
Option          "DRI"                   "false" "

made things worst! X crashes on video playback too!

I had just another crash. All I did was start Firestarter. This is very very inconvenient. :/

It's also possible to revert back to i810 driver instead of intel driver. Its mature and stable enough.

Update: Please switch back to XXA, instead of EXA new acceleration method to see if it helps. Add the following line to /etc/X11/xorg.conf device section:

Code:
Option          "AccelMethod"           "XAA"

I installed the xserver-xorg-video-i810 and kept the xserver-xorg-video-intel. Well, I had too, because synaptic forced me to.

I also added this line
Quote:
Option "AccelMethod" "XAA"


As a newbie I can't be much of a help but I would suggest that a stable version should be used instead of a problematic one.

Thanks for the help. Smile

rfpa,

Would you please all changes you have been made to the configuration file and use the updated xserver-xorg-video-intel driver made available yesterday? Please help me to test its stability status. Thanks.

alan, I just added this option
Quote:
Option "AccelMethod" "XAA"
and installed the i810 driver. I checked the Linux Mint Gnome installed drivers and they have both (i810 and xorg driver intel).

Nothing happened ever since.

i810 driver package is dummy. xserver-xorg-video-intel package contains both i810 and intel drivers. You config is OK. Keep that XAA option and use intel instead of i810 in the /etc/X11/xorg.conf file device section. Thank you.
