** Summary changed: - [i915] external screen stays dark after suspend/resume via lid + [i915] dualscreen: some screen stays dark after suspend/resume via lid
** Description changed: Binary package hint: xserver-xorg-video-intel On Jaunty latest on a Dell Latitude X1 (i915GMS), with an externally - connected Dell 2405 configured for extended desktop, the external screen - stays dark after going through suspend/resume. + connected Dell 2405, the external (sometimes the internal) screen stays + dark after going through suspend/resume via lid close. + + I can mostly recover from the situation by Alt-F1 to shell and + restarting GDM. However, things are very weird afterwards. Both gnome + panels sits directly on top of each other. Maximizing windows on the + external screen result in ~100 pixel wide windows, although the screen + has got 1920 pixels and the desktop background spreads to all of those. + + - Suspending via FUSA or pm-suspend instead works as expected. + - Turning on "Pipe-A forcing" does not help with the problem. + - I have the same issue on Karmic and Non-KMS (either EXA or UXA), but *not* on KMS. + - The bug shows up in either extended desktop or mirrored configuration, does not matter. + - Kind of related: When I deactivate the external display with screen resolution prefs and close the lid, the external display is briefly activated and used for (extended?) Desktop - why? This is a regression from Intrepid and Hardy.
