** Description changed: This is on a freshly installed and dist-upgraded Natty installation. Steps to reproduce: - Plug in an external screen and wait a couple of seconds for it to get recognized. Expected result: - Both screens draw correctly and can be used Actual result: - The background goes "black" on both screens (whereas it should have the default Ubuntu colored background). Unity and the top panel are visible on the built-in display; Only the top panel is visible in the external display. If I open a terminal on the main display, it appears fine, but response is very sluggish; the system takes up to 2 seconds to "catch up" with actions, keystrokes and dragging actions (the cursor pointer itself is fine and tracks movement without any lag). If I drag a window around, other than it being very slow (takes up to 2 seconds to finally catch up with the dragging pointer), it leaves "traces" of itself around, as if the intermediate steps were not being erased before redrawing the window in a new position. This happens in either display. When I unplug the external display, everything goes back to normal. I'm attaching pictures of the internal and external screen upon connecting the external display, of both screens after I've dragged a window around a bit and left a lot of residual window pieces, and how the internal display looks after unplugging the external display (i.e. normal). - Happens on these four systems: + Happens on these five systems: - Three Dell Latitude 2110, slightly different specs - One Dell Inspiron Mini 1018 + - One Asus Eee PC 1001PX The common component seems to be this one: Intel Corporation N10 Family Integrated Graphics Controller - ProblemType: BugDistroRelease: Ubuntu 11.04 Package: xorg 1:7.6+4ubuntu3.1 ProcVersionSignature: Ubuntu 2.6.38-8.42-generic 2.6.38.2 Uname: Linux 2.6.38-8-generic i686 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz Date: Thu Jul 7 14:47:06 2011 DistUpgraded: Fresh installDistroCodename: natty DistroVariant: ubuntu GraphicsCard: Intel Corporation N10 Family Integrated Graphics Controller [8086:a011] (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0461] Subsystem: Dell Device [1028:0461]InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release i386 (20110427.1) MachineType: Dell Inc.
