** Description changed: - Binary package hint: xorg + This bug tracks different issues impacting systems on the target + certification list when running the Unity shell environment in Ubuntu + 11.04 - Steps to reproduce: - 1- Open the Monitors control panel. - 2- Choose a different resolution and orientation (we use 640x480 upside down). - 3- Press Apply. - 4- Select "Restore original configuration" to return to how things were originally. + The complete list of problems covers: + 1. resolution or orientation change in a single monitor setup (Bug #795454) + 2. plugging or unplugging an external monitor (Bug #795458) + 3. panel disappearing (Bug #795459) - Expected result: - - Resolution restores, screen rebuilds and is visually identical to how it was before the resolution changed. + The different issues can occur depending on the GPU brand and driver version used, among the list of recommended configurations: + * for Intel cards, the default opensource driver shipped in Ubuntu + * for Nvidia cards, the default closed-source driver shipped in Ubuntu + * for ATI cards supported by the fglrx driver, the fglrx driver shipped in Ubuntu 11.04 + * for ATI cards not supported by the fglrx driver, the radeon driver shipped in Ubuntu 11.04 - Actual result: - - Display is corrupted in various ways. On some systems only the background or parts of it are visible. On others, there's some misplacement of elements. Some others show garbling on all or parts of the screen. On all systems, moving the pointer, dragging windows or generally forcing the system to redraw seems to eventually restore the display to a usable state. - - We also observed the same problem when plugging in an external display: - the corruption happens when connecting the external monitor, and can be - restored by dragging things around. When unplugging the external - display, the integrated screen becomes garbled as described. - - The systems were originally installed with Natty Beta1 (March 30, 2011), - we did a full update/dist-upgrade on April 7, 2011 and confirmed that - the behavior is still present. - - The system I'm reporting this from is a Dell Inspiron 1545, but about half the systems we tested B1 on exhibited this problem (18 systems out of 32). I'll update shortly with a list of affected - systems. - - Install the update in -proposed: - - check the issue is fixed on intel/ATI - - Affected systems include: - - Sony VGN-Z540 - Dell Inspiron 1545 - Dell Vostro 3300 - Dell Vostro 3500 - Dell Vostro 3700 (2 affected systems) - Dell Latitude 2110 - Dell Latitude 13 - Dell Vostro 3400 - Dell Vostro V13 (2 affected systems) - Toshiba Tecra R700 - HP ProBook 6550b - Toshiba Tecra R850 (Intel) - Toshiba Tecra R850 (ATI) - Acer Aspire One - Dell Mini 10 - Lenovo Thinkpad T420s - Lenovo Thinkpad x220s - - ProblemType: Bug - DistroRelease: Ubuntu 11.04 - Package: xorg 1:7.6+4ubuntu3 - ProcVersionSignature: Ubuntu 2.6.38-8.41-generic 2.6.38.2 - Uname: Linux 2.6.38-8-generic i686 - Architecture: i386 - CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,vpswitch,regex,animation,snap,expo,move,compiztoolbox,place,grid,imgpng,gnomecompat,wall,ezoom,workarounds,staticswitcher,resize,fade,unitymtgrabhandles,scale,session,unityshell] - CompositorRunning: compiz - DRM.card0.LVDS.1: - status: connected - enabled: enabled - dpms: On - modes: 1366x768 1280x720 1152x768 1024x768 800x600 848x480 720x480 640x480 - edid-base64: AP///////wAOFL8UAAAAACUTAQOAIhN4Ck5NnldUkSYPUFQAAAABAQEBAQEBAQEBAQEBAQEBeB1WwlAAJjA7J1oAWMEQAAAaeB1WwlAAJjA7J1oAWMEQAAAaAAAA/gBHNTI2SoAxNTZXQTEgAAAAAAAMEhcePWeg/wEBCiAgAIk= - DRM.card0.VGA.1: - status: disconnected - enabled: disabled - dpms: Off - modes: - edid-base64: - Date: Thu Apr 7 15:13:05 2011 - DistUpgraded: Fresh install - DistroCodename: natty - DistroVariant: ubuntu - GraphicsCard: - ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series] [1002:9552] (prog-if 00 [VGA controller]) - Subsystem: Dell Device [1028:02aa] - InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Beta i386 (20110330) - MachineType: Dell Inc.
