View Full Version : [kubuntu] Lose desktop effects after logout and login again

I'm running Kubuntu 8.10 64 bit with an ATI 4870 graphics board and the latest 9.3 64bit display drivers. So far so good.

After a fresh start or a reboot, I logon into my KDE 4.2.2 desktop and I have desktop effects. Running the fglrxinfo command outputs:

display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series
OpenGL version string: 2.1.8543 Release

Everything looks ok and works ok.

But if I logout and I login again, I loose all the desktop effects. It looks like Kwin as connected to the wrong display.

In this case fglrxinfo outputs an error:

X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 145 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 17
Current serial number in output stream: 17

If I do a CTRL-ALT-Backspace to restart X, the desktop effects start to work again, and fglrxi outputs the initial information.


Any ideas?
