OK, I now have internet at home and I could test the driver 2:2.0.0-6 . Nothing improves, I am afraid.
I tried it with the transparency and shadow effects in KDE. I uninstalled Beryl because it is obsolete, and I don't know how to make compiz work properly in KDE :-) So the following is with the transparency and shadow effects in KDE. If I try to reproduce an AVI file: * Only mplayer plays it OK. * Noatun, totem and VLC crash at the beginning. * Kaffeine does not crash but only reproduces sound, no video. If I try to test the webcam, luvcview hangs: $ luvcview luvcview version 0.2.1 Video driver: x11 A window manager is available video /dev/video0 find DRI X Error of failed request: BadAlloc (insufficient resources for operation) Major opcode of failed request: 141 (XVideo) Minor opcode of failed request: 19 () Serial number of failed request: 25 Current serial number in output stream: 26 Hope it heps, David
