I have tried - a lot. That being said, this happens quite often. I use firefox 3 on Ubuntu 8.04 and browse a lot using Ctrl+click (opening a new tab in the background) and Ctrl-W. At some time (often after 15-20 minutes) the control key seems stuck. Just normally clicking on any link opens the page in a background tab in firefox. Thought this might just affect firefox, but the whole desktop environment is affected, so I guess it must be gnome, somehow. The symptoms are very much like those described here: https://bugs.launchpad.net/bugs/194214 Unfortunately I can't log out normally, because everything I click just seems highlighted. Can't type anything in thegnome- terminal; just have a rectangle where the letters should be. You can see the same thing when just pressing Ctrl in a normal session. I have to either Ctrl-Alt-F1 to a terminal and run "killall gnome-session" or kill the X-server via the Ctrl-Alt-Backspace combination. Because I have not found an easy way of reproducing this bug (quickly!) I guess it will be closed as incomplete, but since this has happened quite a few times since the launch of 8.04, I though I might report it.

[Kernel-packages] [Bug 1579374] Re: amdgpu causes NULL pointer dereference when trying to use Topaz (Radeon R7 M265) GPU
** Also affects: linux Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1579374 Title: amdgpu causes NULL pointer dereference when trying to use Topaz (Radeon R7 M265) GPU Status in Linux: New Status in linux package in Ubuntu: Expired Bug description: A Dell Inspiron 5448 / 0YDTG3 laptop (BIOS A06 10/12/2015), which used to work well with Ubuntu trusty and Ubuntu wily releases (using fglrx driver), has an issue in Xenial where when the amdgpu driver tries to activate the Radeon GPU, a NULL pointer dereference occurs, causing the caller process to hang. This practically causes the system to hang when trying a logoff or shutdown. The bug can be easily reproduced by calling: DRI_PRIME=1 glxgears Which hangs the glxgears process and causes the stacktrace attached below. ---[cut]--- $ dmesg [...] [ 129.188685] [drm] PCIE GART of 2048M enabled (table at 0x0004).
