I've just tried the latest mainline build: linux-image-2.6.34-999-generic_2.6.34-999.201004281008_amd64.deb The result was the same.
Also, I think I pasted the wrong kern.log output into my initial report - those lines were in relation to a different unknown key. Here's the log entries from the mainline kernel, this time regarding the correct unknown key: atkbd serio0: Unknown key pressed (translated set 2, code 0xf7 on isa0060/serio0). atkbd serio0: Use 'setkeycodes e077 <keycode>' to make it known. ** Tags removed: needs-upstream-testing -- [STAGING] Decrease brightness hotkey on MSI U200 not recognised https://bugs.launchpad.net/bugs/560062 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
