Jeremy, I am back to Alpha 1 (on SL). There is no problem as long I am staying with X11 - but at the moment I switch to any other application e.g. finder or whatever and I am going back to X11 I can't use it anymore. Interestingly, though I cannot click into any application under KDE I can start a Terminal from the X11 menu but I cannot type anything in it. Here is the log and the X11 process print - not sure if it helps - and this time no wacom attached :-) the CPU does not go crazy at all. christof 13.10.09 23:16:31 [0x0-0x5ec5ec].org.macosforge.xquartz.X11[25800] X11.app: main(): argc=2 13.10.09 23:16:31 [0x0-0x5ec5ec].org.macosforge.xquartz.X11[25800] argv[0] = /Applications/Utilities/XQuartz.app/Contents/MacOS/X11.bin 13.10.09 23:16:31 [0x0-0x5ec5ec].org.macosforge.xquartz.X11[25800] argv[1] = -psn_0_6211052 13.10.09 23:16:31 [0x0-0x5ec5ec].org.macosforge.xquartz.X11[25800] Waiting for startup parameters via Mach IPC. 13.10.09 23:16:31 [0x0-0x5ec5ec].org.macosforge.xquartz.X11[25800] X11.app: Could not connect to server (DISPLAY is not set).
