ASUS P5W DH DeLuxe mainboard
Gainward Bliss 7300LE graphics card
Debian Testing (up to date) with kernel 2.6.20.1 and Xorg
This is in two parts.
1. Using the Xorg nv driver the display is, in general use, perfectly
acceptable but when restoring the screen after the screensaver has
blanked it or switching back from a text console to the X display I
sometimes get a very peculiar effect.
It is almost as if parts of the display appear as a negative - white
becomes black, yellow becomes blue etc. Any text appears very broken to
the point that it is illegible. This only affects parts of some areas
of colours i.e. an area of yellow will appear blue in the top half but
yellow in the bottom half but another area of white will appear black
all over. Have you ever seen a little Tux with green feet?
If I then switch to a text console and then back to the X display it
nearly always rights itself although sometimes two or more switches are
necessary.
It cannot be produced on demand. Switching consoles sometimes has no
detrimental effect. I did, once, save the screen to a graphic image to
try and demonstrate the effect but when viewed the screen in the image
looked perfectly normal!!!
====================================================================
2. After the above problems wouldn't go away I installed the nVidia
driver from the nVidia web site.
To date, I have no problems under X. However when I boot the machine (I
have vga=extended in my lilo.conf) the console display is fine until
the nvidia driver is loaded. If I then switch back to any text console
every line is displayed one and a half times, which is very difficult
to read, and, with a screen full of text, the prompt is off the bottom
of the screen.
Reverting to vga=normal and re-running lilo cures the problem but I
would prefer to keep vga=extended.
Does anyone have any ideas or suggestions regarding the above? I would
really appreciate some help on this.
