Description Danny Baumann 2007-10-16 12:47:15 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:188.8.131.52) Gecko/20070718 Fedora/184.108.40.206-1.fc7 Firefox/220.127.116.11 Description of problem: In Fedora8 test3, I can't no longer use the brightness adjust keys of my Toshiba Satellite Pro A100 laptop. Instead of being recognized as brightness change keys, Fn+F6/7 are recognized as regular F6/7 keys. This used to work fine with Fedora7's kernel 18.104.22.168-91 kernel. Adjusting the brightness itself (via writing to /proc/acpi/video/VGA/LCD/brightness) works fine, though. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Grab a Toshiba Satellite Pro A100 laptop 2. Press Fn+F6/7 3. Actual Results: Key code for F6 is entered (tilde appears in the console). Expected Results: Brightness of the LCD is changed. Additional info:
Comment 1 Jeremy Katz 2007-10-16 14:09:52 EDT
Is there anything in dmesg about unrecognized key scancodes?
Comment 2 Danny Baumann 2007-10-16 14:25:53 EDT
(In reply to comment #1) > Is there anything in dmesg about unrecognized key scancodes? No, there isn't. As mentioned above, the Fn+F6/7 keys emit the normal F6/7 keycodes (64/65) in the 2.6.23 kernel; in the 2.6.22 kernel they don't emit any user-visible keycode.
Comment 3 Danny Baumann 2007-11-01 05:11:42 EDT
Upstream bug report: http://bugzilla.kernel.org/show_bug.cgi?id=9262 Comment #10 contains a patch that's working fine and is supposed to be non-invasive.
Comment 4 Danny Baumann 2007-11-02 10:45:04 EDT
FYI: There is another, somewhat related, upstream bug report: http://bugzilla.kernel.org/show_bug.cgi?id=9277. The patch in this bug fixes weird flickering with brightness-applet and gnome-power-manager being unable to set the brightness above 35% on Toshiba laptops.
