So why can't I get Debian (2.6.x kernel) to go any higher than 1024x768 res.?


On kernel 2.4.x I was able to get it up to 1280x1024 resolution, but with the newer 2.6.x kernel, no matter how many times I run the XF86Config-4 setup it won't (and the modes actually list 1280x1024) do anything higher than 1024x768 in X-windows.

I've tried a couple of different X-window managers too and it's the same story. Nothing higher than 1024x768.

Help!

Yeh I've run that and told it to put those resolutions in, but for some reason it keeps on not displaying them as viable resolutions when KDE is loaded.

You need to specify the correct hsync and vrefresh range for your monitor.

Triple checked. They are set correctly.
One other interesting piece of information. It is also including resolutions I didn't specify to be in there such as 640x480, 640x350 etc.

Telling us what kind of graphics card you've got (lspci | grep VGA) might help in troubleshooting.

Boot a Knoppix live CD take the settings from that, only way I got the resolution I wanted in Gentoo

The i810 driver should work with that graphics card. It's very strange that changing from the 2.4 to the 2.6 kernel affects the available screen resolutions because both kernels should come with the same driver.

After you've selected the correct driver and specified the correct refresh ranges for your monitor (from the monitor's manual), it's usually just a matter of picking the desired screen resolution in "dpkg-reconfigure xserver-xfree86".

Notice that the X server tries the resolutions in the order that they are mentioned in XF86Config-4. If you have DefaultDepth set to 24 under the Section "Screen" in XF86Config-4, then the Modes line under SubSection "Display" and Depth 24 should have first "1280x1024" and "1024x768" after that (so that the X server has something to fall back to if it cannot for some reason set the screen to 1280x1024).

If you think you have set everything correctly, then maybe /var/log/XFree86.0.log shows some additional info that could help in troubleshooting the problem?

Can't you just add it manually?
Should be something like this:
Quote:
Section "Screen"
Identifier "Default Screen"
Device "Generic Video Card"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600"
EndSubSection
workes for me ...

That's the config of my XF86Config-4 file for right now. I will try adding the 1024x768 res to the file and see if that fixes it. What's odd is it only lists 1280x1024, but it runs in 1024x768.

Very odd.

I did reboot it. I'll give it one more try, but I don't think it's going to work.

What happens if you use only one depth?

Replace all this:
