Please attach your xorg log and dmesg output. What chip is this and what size screens are you trying to attach? I suspect the total size of your desktop exceeds the max texture or renderbuffer size supported by the hardware.

Graphic card: Radeon Mobility X600
The graphic chip is a:
Radeon Mobility X600 (M24) 3150
You are hitting the hw limits of the chip. R3xx asics have a max texture coordinate limit of 2048x2048 pixels. You desktop is 2800x1050 in left/right orientation so it exceeds the hw limits. Hello, my problem is solved, because Alex gave a hint that this issue must have to do with 3D effects. I went in "Configure Desktop" to "Workspace Appearance and Behavior" ---> "Desktop effects" ---> "Advanced" and I changed the "Composition type: OpenGL" to "XRender". After that I could use the "Position: left of" in "Configure Desktop" ---> "Display and Monitor" ---> "Size and Orientation". Thank you very much for the help. Juergen Confirming this. Using xf86-video-ati from git (snapshot from 12.02) KDE desktop looks skewed on dual head setup, when monitors are side by side. Doesn't happen with previous versions. My chip is Juniper, HD6770. Sizes of screens - 1: 1920x1200 2:1680x1050. (In reply to comment #7) > Confirming this.

Please open a new bug and attach your xorg log and dmesg output. |

Created attachment 57403 [details] Output of the command: xrandr -q Hello, I have a second monitor attached to my laptop. This VGA-0 monitor works fine when I use "Position: clone .." and "Position: under.." in the kde4 system settings, but when I try "Position: left .." both screens are messed up? Everything worked with openSuSE 11.2 but not with my new installed version of openSuSE 12.1. I will attach the output of command: xrandr -q I can also attach the file: Xorg.0.log if you need this information. If you need more information, let me know. Thanks for your help. Juergen
