 |
|
Hey there,
I have this peculiar problem - X server runs just fine, but if I try to switch to an alternative virtual terminal or when I exit the screen begins to flicker really bad. And it won't fix until I reboot. It's as if the monitor frequency is scrambled..I've run xorgconfig countless times trying all combinations of frequencies and video drivers but still nothing. Any thoughts would be greatly appreciated. I'm running Gentoo on a 1.8GHz laptop with Intel 855GM, 64MB video card.

| Sometimes this sort of problem can be caused by incorrectly configured framebuffer support. Are you using framebuffer? If so, could post the relevant bits of grub.conf and your kernel configuration? |

| Thanks for the reply. It really turned out that the problem was caused by the framebuffer. I simply switched from vesafb-tng support to vesafb and added the vga-statement separately from the video-statement and it worked :D |

A few months ago - of course after an emerge world - this laptop exhibited the problem described above. I just started trying to correct it.
My BIOS is already set to LCD Mode (LCD Only). Here is my grub.conf:
| Code: | timeout 3
default 0
splashimage=(hd0,0)/grub/splash.xpm.gz
# boot Gentoo Linux 2.6
title=Gentoo Linux 2.6
root (hd0,0)
kernel /kernel-2.6.17-gentoo-r8 root=/dev/hda3 vga=0x318 |
I am going to look at my framebuffer settings - once I remember where those are. I believe I have seen mention of xorg re-configuration solving this issue...but cannot find that note right now. Any other suggestions?
Edit: Just verified my kernel options: no support for framebuffer here. Now what?

Changing my DefaultDepth from 24 to 16 corrected the problem. I can repeat the problem/fix every time by switching between those two settings.
Here are the relevant lines in xorg.conf:
| Code: | Section "Screen"
Identifier "Screen 1"
Device "Dell Latitude VGA"
Monitor "Dell Latitude LCD"
DefaultDepth 16
Subsection "Display"
Depth 8
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 16
Modes "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
Subsection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
