At completely random intervals, I seem to be getting some weird horizontal line distortions that cross the entire width of the screen, and appear at completely different heights… sort of like the distortions you get when you’re viewing a video tape that’s strip has been bent. This I find very disturbing, especially considering that I have absolutely no idea what might be causing this issue… anyway, lspci identifies my graphics card as the following:
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Might this be a config/driver issue with this device, or what must I do to determine the actual issue here?
I think the bios has already been updated, and the issue doesn’t occur on WinXP, but GRUB didn’t have the “i915.powersave=0” parameter… I haven’t noticed any more distortions since booting with it, at least yet, so I think that must have been my problem; thanks user2304!
Hi. i have a similar problem. i have the i845G/GL chipset and i’m using 11.3. The fonts randomly disappear or change colors. For example, right now i have opera and dolphin running, and on my panel(using latest kde) i see the windows, i see the icon’s in the buttons, but no font. just black. i didn’t have this problem with 11.2 so i might go back, unless someone knows how to help me fix this.
