** Description changed: System: Intel Mac Mini Core Solo, 2M RAM, Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) Software: Kubuntu 9.04 updated on 4 April 2009. I am using a xorg.conf containing Option "AccelMethod" "UXA" and no driver is specified. After the last (large) update, at login I get a corrupt screen that is divided into 5 vertical bands, each band containing hundreds of light and dark horizontal stripes in a cyclic pattern. The login window, and text, is visible behind this but has many dark spots where the rendering has failed. I can enter the login password but soon after that, when showing the last icon in the middle of the screen, X freezes, apart from mouse movement. No response from keyboard. Have to power down. I can get round this by switching to tty1 immediately after entering the password (so I don't see the icons on the foreground screen) then waiting until I hear the logon sounds. Then I know it is safe to switch to tty7 and view the graphics sceen. This is a repeatable workaround but obviously not ideal. I found that turning off desktop effects got rid of the problem completely. Also I tried regenerating xorg.conf using dpkg-reconfigure. This produced a vesa driver version of xorg.conf. This vesa version works without problem and there is no noticable difference in performance compared with the UXA version I was using before. This problem did not exist using desktop effects before the last update. Incidentally I tried using the ubuntu-bug command as printed below and all I got was a usage message. My command did conform to the usage message syntax but the command was not accepted. + + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub [8086:27a0] (rev 03) + Subsystem: Intel Corporation Device [8086:7270] + 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] (rev 03) + Subsystem: Intel Corporation Device [8086:7270]
