When I examined the function key press using logkeys (http://code.google.com/p/logkeys/) I noticed that a single key press of the Function key alone registers two times.
<E-1d0><E-1d0> The documentation for the logkeys logfile format, indicates that 1d0 is the keycode in hexadecimal format. Perhaps this registration of this keypress two times is contributing to the error? Is the patch mentioned by Martin in comment #60 supposed to remove the instability during brightness adjustments? I'm using kernel version 2.6.38-8 and still experiencing the issue. I am not sure where to check in the /sys or /proc filesystem to determine the number of brightness levels that are supposed to be available to the system, or the current setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/446717 Title: [gm45] Adjusting Brightness in Acer Aspire Timelines causes system freeze in 4810T and 5810T models -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
