Unable to get 1024x768 working

Asked by AlexD

Hi, I just installed Ubuntu 7.10 and I have been unable to get 1024x768 working properly. 800x600 works fine. 640x480 is also fuzzy. When I switch to 1024x768, I get a 1" black bar on the right side of my screen, about 1" of missing screen space on the left side and the entire screen is fuzzy/flickering. I have looked through all documentation I could find online with no luck. IRC was no help either, they just referred me to things that I already knew. I'm hoping that by centralizing all efforts in one place, that a solution will be reached quicker :D

Hardware:
Compaq Evo N800c laptop w/ built in 14" LCD
ATI Mobility 7500
Max res is 1024x768. This works on Windows and worked on the last Linux distro I put on here (Gentoo ~2 years ago).

I have tried dpkg-reconfigure server-xorg with medium settings. The auto-detected settings give me the above problems.

I have *NO* idea what the correct hsync/vref settings are for my screen. I have checked google/all manuals/etc.

Please help! If you need any more info, please post and I will update ASAP.

Greets. I'm not sure if you are aware of this or not, but your laptop's native (optimal) resolution is actually 1400x1050. You can try to get 1024x768 working, but I would suggest working towards the higher resolution, since the screen quality will look far better!

First, exit out of your X environment with Ctrl+Alt+F1.

Log into the console, and shut down GDM:
$ sudo /etc/init.d/gdm stop

Reconfigure X:
sudo dpkg-reconfigure xserver-xorg

If prompted for your video card settings, select ATI, and choose the resolution of 1400x1050, 1024x768, and 640x480.

If 1400x1050 is not available, try adding the value to your xorg.conf file after the fact:

Modes "1400x1050" "1024x768" "800x600" "640x480"

Please report back with results.

No luck. Re-ran dpkg-reconfigure xserver-xorg and specified 1400x1050, and then checked the Modes line in xorg.conf. It is:

Modes "1400x1050" "1024x768" "800x600" "640x480"

Then I restarted X (ctrl-alt-backspace) and 1400x1050 does not show up under System > Administration > Screens and Graphics and Preferences > Screen Resolution.

With all that said, I am 99.99% sure that this laptop maxes out at 1024x768. Its more than 5 years old and I have never seen 1400x1050 pop up anywhere (windows, linux, you name it). Even then, theres no reason why 1024 shouldn't work.

Just tried using the xorg.conf that I got from the knoppix CD... same issue. This makes me think that it is a bug/issue with X rather than my settings.

Ahh... it depends on the screen your model came with.

Do you know which screen type you have? We might be able to find a working xorg.conf file if we have the specifics.

I have no idea what screen it is. I am fairly sure it is the 14.1" XGA because it maxes out at 1024x768.

Here's the thing, the 2nd xorg.conf I posted works fine on Knoppix, but not on Ubuntu. If you want I can get the versions of all the things on that CD if you tell me which ones you need.

Try adjusting your VertRefresh and HorizSync values to the values that worked in Knoppix.

HorizSync 28.0 - 96.0
VertRefresh 50.0 - 75.0

I figured out what the problem was... changing my video driver from ati to vesa fixed the problems! Thank you for all your help Gilbert!
