Public bug reported: Binary package hint: xorg
If you do the following actions, the desktop environment (tested in KDE and Gnome on same install) will freeze. The mouse moves, applications continue running, and visible animations (such as knemo) will continue to be animated. But key presses or mouse clicks are ignored. 1. Open opera (version 10.10). 2. Display the previous-addresses list, either by typing some letters in the URL field or clicking the drop-down arrow next to the field. 3. Click the tray icon to hide opera. (At this point, KDE/Gnome freezes. The mouse won't register on the taskbar, other windows, system tray, etc, and global keyboard shortcuts, alt-tab, etc don't work. However, Opera's own keyboard commands will still work. If this happens, it is recommended to press Alt-F4 and quit opera.) 4. Press tab. (This moves focus off the address field. Opera is hidden and the GUI becomes responsive.) 5. Click the tray icon to display opera. (At this point, KDE/Gnome freezes, and Opera no longer responds to its own keyboard shortcuts.) It is possible, randomly, for opera to restore with the cursor in the URL field, so that only step 5 is necessary. But it takes all the steps to reproduce the bug at will. This isn't a total crash, as alt-sysrq-k and ctrl-alt-f# still work. You can avoid killing X by changing to tty1 with ctrl-alt-f1, logging in, typing 'killall opera,' and then changing back with ctrl-alt-f7. The original bug is clearly in Opera, and I've reported it to them. It might be fixed in a later release. However, it should not be possible for an application's GUI to kill Ubuntu's entire GUI. At most, only the misbehaving application should freeze, allowing the user to kill it without leaving X.
