Title: [ffe] unplugging an external monitor from laptop results in corrupted screen. Logging out fixes it. Status in X.org xf86-video-intel: Fix Released Status in “xserver-xorg-video-intel” package in Ubuntu: Fix Released Bug description: [Impact] With updated 13.04 beta, unplugging an external monitor from laptop results in corrupted screen. Logging out fixes it. A screen capture looks normal (not like what the display is showing!). Plugging an external monitor in does not produce any similar problem. [Test Case] 1. On affected hardware, boot with an external monitor connected 2. Unplug the external monitor Expected behavior: Normal screen Actual behavior: Screen corruption [Development Fix] The fix for this issue is a cherrypick of an upstream patch with a minor change to make it apply to raring. (See comment #56) The upstream patch is rather large (~228 lines), but half of that is simple code refactoring (moving some common code into functions, moving some functions earlier in their files so they can be referenced in other routines, etc.) For review purposes, a cleaned up (uncleaned up?) version of the patch is available in comment #59, which shows just the functional changes to the code. [Regression Potential] The patch originates from an upstream change that has not been part of a release yet, but has gone through upstream review and testing. This patch primarily *adds* code, and most of that is cleanup code to clear graphics memory and free pointers, which should be quite safe. However, cleanup code can sometimes expose pre-existing bugs (e.g. freeing invalid pointers that otherwise would have been ignored). We don't expect that to happen, though. A few while loops are added. It does not look like the code could get stuck in those loops, though. Types of symptoms to look for include X server crashes, gpu lockups, and screen corruption, particularly associated with screen initialization, destruction, or resizing.
