Trouble with Suse 10.1 Screen Resolution

JM Allard · 07-28-2006, 05:36 PM

First off, I should say I am a Linux noob. I am having trouble changing the screen resolution in Suse 10.1 with the KDE desktop. When I go to the Configure Desktop and then to the Display tab and try to change my resolution from the drop down menu the only choice I have for a resolution is 640x480 and this is a pain in the butt to use. My monitor's native resolution is 1280x1024 and was displaying perfectly during the installation. Even when hardware was being recognized Suse saw my graphics card (ATi Radeon X800XL) and displayed my monitor's resolution as 1280x1024. I don't know what's up with this. Is there any way to force Suse to change the resolution? Should I abandon this install and go back to Suse 10.0, because I had that working fine with my monitor? Thanks in advance for the help

I figured it out. I apologize for cluttering up the forum. What I did was open up Konsole, typed "sax2" without the quotes, hit enter, typed my root password then changed the screen resolution under the monitor tab. Clicked Ok tested the settings, and saved them. Then all I had to do was end my session and log back in, with Suse supporting my monitor's native screen resolution! Once again, I am very sorry for cluttering up the forum.

Don't worry about cluttering the forum; now I know how to fix this, and so does anyone else who searches for it. If everyone came back and told us how they finaly fixed a problem we would all be better off.

Thank you.

I started with PCLinux and couldn't fix that. Then went to SuSe 10.1, same problem. Now i'm running Mandriva and trying to fix it there.

The sax2 command didn't work. Is there another work around for this??

If the resolutions you want are contained in your xorg.conf file, you can use the krandrtray kde tray application to change the resolution on the fly. Perhaps X windows isn't configured to include other resolutions. Your best bet in SuSE is to run sax2.

sax2 command is a SuSE utility, so it wont work on other distros.

If you are runing SuSE 10.1 with KDE, goto K menu then find YasT2, it's like control pannel under windows, you can change it from there.

A general solution is to change your xorg.conf file I guess. There is a file called xorg.conf under /etc/X11. Open it with your favourite text editor(vi, emacs etc...) with root access. Then find a section called:

Code:

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x800"
        EndSubSection
EndSection

See the modes? If there's only 640x480 there, add a resolution you want.(for exp, I added "1280x800" for my widescreen)

I'm a retard at editing files, but i was able to pull up the info in xorg.conf. my screen resolution IS listed, however it is NOT listed in the KR and R Tray.....

You could in KDE enter "[ALT]-[F2]" to bring up the run dialog and enter "kdesu kate /etc/X11/xorg.conf" in order to manually edit the xorg.conf file. Mandrake uses XFdrake to make video adjustments. You might want to read the xorg.0.log log file in /var/log/ and see if some of the resolutions were rejected.
