As always, the latest version of Ubuntu, 9.04, was released on time. It offers faster boot time, ext4 support, and many other minor updates and tweaks that makes the system better. Unfortunately, in addition to the updates, there’s a fairly serious (aka, annoying) bug in Ubuntu 9.04 that causes a certain combination of buttons–most commonly, the Fn+UP/DOWN and volume buttons—to render the keyboard completely dead, as well as the system menus and the right-click menu that appears when using the mouse. This bug appears in many different ways, as evidenced by the varying bug reports, but it always has the same symptoms.

While there’s no reported cause for the bug—only acknowledgement that it exists—users are forced to hard reset their system to correct the problem; restarting the X server is impossible, due to the lack of keyboard, and the system menus disappear, preventing a simple log in/log out fix.

Because a hard rest is not a viable option when using the system for work (or at all, for that matter), it would seem those plagued with this bug are forced to install 8.04 or temporarily abandon their system for a different one. Luckily, if you’re willing to stick it out for awhile until the coveted bug fix is released, there is a simple solution to unlocking the keyboard that does not involve a hard reset:


Or any other key F1-F12. The screen will temporarily turn black, and a system beep might occur, and then the keyboard and menus will continue working as normal. The buttons that trigger the bug will continue to act poorly, however.

If you’re experiencing their bug with your system, be sure to report it so that a solution can be found as quickly as possible.
