Dual Monitors and openSUSE 11.3

Good day,

I am having a challenge with dual monitors on an ATI Radeon HD 2600 Pro AGP video card. It is necessary to set the configuration every time I boot the system. By default at start-up DVI-1 (LCD) clones DVI-0 (CRT).

I want to show one large desktop across two displays.

Setting the display has to be performed under Size & Orientation of System Settings. If I click on Multiple Monitors, I see a message to the effect that I do not appear to have the configuration of multiple monitors.

One monitor is DVI, the other is analog with an adapter at the video card from DVI. Resolutions are identical at 1280 x 1024. The analog (DVI-0) is 75 Hz. The digital flat-panel (DVI-1) is at 60 Hz. Both of the Hz settings and the resolutions are as set by the OS.

Thanks for taking the time to read this. Have a Great day.

I would give that a shot. I think the main thing is having the ATI drivers installed.

Thanks for the reply. If it came about 24 hours earlier, I may not be in the mess I find myself. In hunting for a solution I came across this: openSUSE 11.3 | SUSE Linux | Beginner’s guide to multimedia codecs MP3 DVD 3D nvidia ati wireless I installed the package and it’s the ATI Catalyst Control Center. It provided dual monitor definition but on reboot made a mess of things. My screens are a mess of illegible rainbows.

Now I’m looking for a way to revert things through Failsafe command line. Luckily I have my Ubuntu partition still active so I can hunt for a solution. But I’m not experienced enough to figure it out easily. I’m not command-line shy, just wandering through the forest.

Again, thank you for the help and reading this.

I think that the ATI config tool will have generated /etc/X11/xorg.conf, so you could just delete this file (or rename it if you prefer).

sudo rm -f /etc/X11/xorg.conf
sudo mv /etc/X11/xorg.conf xorg.bak

This thread might be helpful to you with getting your display config to stick.
