I see only half the screen when i change resolution! [repost]


hi, forgive me for the repost, but i kept bumping my first post and got no replies, and i think maybe some people dont look into posts with replies, so here it is again:

Hello!

Im running a debian unstable build, with a 2.6.6 kernel, and also a 2.2 kernel, and kde 3.2.2... I have an nvidia Aladdin TNT2 G. card, using the nv drivers, and a viewsonic display, with refresh rates of 30-70 and 50-150..

the problem I am having is that if i lower my resolution during runtime, using xrandr, the kde control center, or screen rotate&resize, i see only part of the desktop.. it is not scrollable, like with the alt + ctrl + +\- resizes.

I have tried reconfiguring X by hand and using the utilities, and no luck so far...
I suspect this is an X bug, because if I delete the higher resolution from the config file, i see it fine.. (i think it forgets to tell all the windows including KDE about the resize) but i wanted to make sure before filing a bug that i havent missed anything..

I have talked to someone has that has the same problem, and he also has an nvidia card, but with nvidia drivers... thi hasnt happened in any of the previous distros i tried, so i dont think this has something to do with my card...

heres my XFree86-4 file:

# XF86Config-4 (XFree86 X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

I had the same problem. I'm using debian testing, with the 2.6.3 kernel -- how did you upgrade to 2.6.6 -- with kde, a geforce2 card with the nvidia driver installed. When I first ran dpkg, I set the allowable resolutions to 1280, 1024, 800, etc. as you did. The default resolution when I started up the computer was 1280x1024, and whenever I changed it to 1028x768, I would lose a good chunk of the screen.

My fix: I ran "dpkg-reconfigure xserver-xfree86" (as root) and removed 1280x1024 as an allowable resolution, which I never use anyway. Now the default is 1024x768 and I don't have to change resolutions, so no problem.

When I installed debian it came with kernel version 2.6.3. How did you manage to upgrade to 2.6.6?

Not sure about a more permanent fix for the resolution problem. Post back here if you get an answer.

I will... as to the kernel, you can get a newer Image from apt, or you could get 2.6.6 sources and compile your own kernel...
