Opensuse 11.3 using KDE.
ATI Catalyst 10.10 drivers installed for use with a 5850
After attempting to get aticonfig to setup my dual monitor setup (dual-head, horizontal) and then rebooting, the second monitor is completely black, though the OS appears to recognize it as a display, kind of. . .
The mouse cursor will move the second monitor, but the cursor changes to an X symbol. There is no background. I am unable to move windows to the second monitor.
I have been able to get both monitors into this state independently with different settings. KDE’s configure desktop applet only shows one of the displays as configurable. I’ve done a few installs and removals of the Catalyst driver to correct this behavior. Upon a fresh install of the drivers, both monitors are functional, but only as a clone of one another. As soon as I attempt to set it to dual head and horizontal, a monitor blacks out upon reboot.
Any help would be appreciated.
Edit
Additional information - The graphics drivers seem to work beautifully in Ubuntu, with the proprietary drivers being found, recognized and installed pretty much automatically by the system. Everything was configurable through the settings within Ubuntu. Not trying to knock Opensuse, just giving it as a reference point illustrating that there is a known-good configuration and it is not a hardware issue, per se. Trying Opensuse instead of Ubuntu because of seemingly irreconcilable issues with wifi/WPA.
I’m assuming that you were using the Gnome desktop environment with Ubuntu. If so, that may also explain the better behaviour with respect to dual screen support. KDE4.X is still problematic for some users with multi-screen configurations.
Similar thread I found on KDE forum.
See if anything here helps:
X.Org/Dual Monitors/ATI - Gentoo Linux Wiki
Hopefully others with similar graphics hardware and dual display setup can assist further here.
To set up the monitors the following command should be used,
amdxdg-su -c amdcccle
This should be available under the
- KDE icon

This program modifies the xorg.conf file but sometimes does not remove unwanted
entries from a previous setup. The file on my machine is as follows, hope it is
of some help. At times this file has erroneously contained more Monitor & Device
sections which confuses X11.
