At random moments (often when opening a new page in chromium-browser-6.0.401.0-alt1.r47010), the screen is blanked (more precisely, filled with one color: black, or the blue color of the Chromium's window). One can successfully switch to a linux text console. But this state of the graphics screen stays "forever" until a reboot: restarting X doesn't help.

This happens rather seldom; and is not deterministically reproducible.

I've found some discussions of similar problems:

http://www.wilderssecurity.com/archive/index.php/t-265302.html -- "The screen going blank (well, all one color) on random events, e.g. clicking a menu"

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/399636

I haven't yet tried whether the 2 mentioned workarounds work for me:

1) "pressing Fn+F7 (LCD/CRT toggle)" -- because I haven't yet experienced this once again

2) Option "ForceEnablePipeA" "true"

No, this doesn't help.

This also happened during video-conversations in skype.

This also happened on 2.6.32-un-def-alt5 and that xorg-drv-intel-2.4.3-alt0.M41.1 (when working in rxvt-unicode-9.02-alt1). So, I will try upgrading xorg-drv-intel from 5.1.

В 4.1/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф.
