Description Sam Morris 2009-03-27 10:21:39 UTC

I have a Samsung Q45 laptop. Pressing the brightness up/down keys causes the kernel to emit a key down event; subsequent presses emit a key repeat event. No key up event is ever emitted.

I originally filed this as a bug in Xorg but was told it was a kernel problem. You can find the output of 'evtest' for the key at <http://bugs.freedesktop.org/show_bug.cgi?id=20862>.

User impact: pressing the brightness up/down keys causes gnome-power-manager to grab the keyboard, and since the keys are never released (at least according to the X server), it becomes impossible to use the keyboard or open any menus until I perform magic (log in via other means and kill gnome-power-manager). Original bug filed at <http://bugzilla.gnome.org/show_bug.cgi?id=576283>.

Could I please have output of 'dmidecode' on your box? Thanks!

Is there a way for me to flick the status back to UNCONFIRMED or similar? GNOME's bugzilla allows end-users to do this but I'm not sure how to do it here...

Any chance you could try 2.6.30-rc3?

Comment 5 Sam Morris 2009-05-01 13:30:39 UTC

This appears to be fixed with 2.6.30-rc4. Thanks!
