Issue in changing monitor resolution

English Hardware
1

Hi,

I’m using openSUSE 11.1 with KDE 3.5 desktop. I have connected an external display to my Dell laptop. The resolution of my monitor is 1920x1080. I think in KDE 3.5 my external monitor is taking the resolution of my laptop screen. I have an Intel graphics card that came with the laptop. So when I click Configure Desktop > Hardware > Display it gives the following error.

Your X server is using the RandR extension at version 1.2 or greater which doesn’t have any configuration yet

When I type xrandr -q on the terminal this is the output it gives

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 1200
VGA connected 1024x768+0+0 (normal left inverted right x axis y axis) 509mm x 28 6mm

800x600 60.3 56.2

I can’t open KRandRTray from either the console or through the system menu. It just doesn’t load up.

The strange this is I can set up the resolution on the monitors correctly on KDE 4 but I want to use KDE 3.

Thanks.

Your X server is using the RandR extension at version 1.2 or greater **which doesn’t have any configuration yet **

The above line is the key. KDE3 never got the ability to configure it and it’s likely never to get it. KDE4 does have this functionality.

I can’t help but think that there’s a way to make KDE3 just use the X settings, but I’m not sure how.

Using SaX2 X11 System I was able to change the resolution to 1920x1080 and it asked me for a restart to get that resolution.

When I restarted, at first it looked as if it had the resolution I wanted, but then the screen went blank and I was back to the old resolution.

I think you have to somehow tell KDE3 to use the X configuration. But I haven’t used that environment for quite a while now, so I haven’t a clue how. Maybe someone else here will know?

This thread from a Debian site might help give you an idea. Not sure, though.

Cheers for the link. I couldn’t find anything to help me there though. I think I might need to change the xorg.conf files but I’m not sure what to change there. Anyone here knows what I need to modify?

I’m able to set the correct resolution now.The problem was randr was set to unify outputs. I deselected this. Then I was able to set a different resolution for my external monitor.
