|
Whenever I run glxgears in my xterm I see sparkling horizontal white lines in and around the xterm. When I run glxgears I get:
bash-2.05b$ glxgears
5152 frames in 5.0 seconds = 1030.400 FPS
7153 frames in 5.0 seconds = 1430.600 FPS
7151 frames in 5.0 seconds = 1430.200 FPS
7153 frames in 5.0 seconds = 1430.600 FPS
7154 frames in 5.0 seconds = 1430.800 FPS
7152 frames in 5.0 seconds = 1430.400 FPS
6310 frames in 5.0 seconds = 1262.000 FPS

I am running gentoo with fvwm as a windows manager on a Dell Inspiron 5150 with a 15" UXGA at 1600X1200. I have set the hsync 43-85, vsync 40-60. I got these values from here. As far as I know Dell has never released the hsync/vsync valules for these LCD screens. I am running XFree86. Does anyone have any ideas why I would be seeing horizontal sparkling white lines?
-- EDIT --
I just ran dmesg and I noticed a couple things.

There were a few of those Debug messages, but you get the idea. The funny thing is that it says that it says an an Intel 855PM Chipset was detected however I have an Intel 825PM Chipset.
