Description Bastien Nocera 2007-04-25 10:30:39 UTC

kernel-2.6.20-1.3104.fc7

Some keys on the Dell Latitude D420 don't have any keycodes associated to them.

What the keys do is explained at:
http://support.euro.dell.com/support/edocs/systems/latd420/en/PG124en1/keyboard.htm#wp1050757

Fn+F3 (power preferences?):
Apr 25 11:23:10 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x87 on isa0060/serio0).
Apr 25 11:23:10 snoogens kernel: atkbd.c: Use 'setkeycodes e007 <keycode>' to
make it known.

Fn+F7 (change display aspect ratio):
Apr 25 11:23:33 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x8f on isa0060/serio0).
Apr 25 11:23:33 snoogens kernel: atkbd.c: Use 'setkeycodes e00f <keycode>' to
make it known.

Fn+F8 (CRT/LCD):
Apr 25 11:24:01 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x8b on isa0060/serio0).
Apr 25 11:24:01 snoogens kernel: atkbd.c: Use 'setkeycodes e00b <keycode>' to
make it known.

Fn+Up (Brightness up):
Apr 25 11:24:36 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x86 on isa0060/serio0).
Apr 25 11:24:36 snoogens kernel: atkbd.c: Use 'setkeycodes e006 <keycode>' to
make it known.

Fn+Down (Brightness down):
Apr 25 11:24:54 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x85 on isa0060/serio0).
Apr 25 11:24:54 snoogens kernel: atkbd.c: Use 'setkeycodes e005 <keycode>' to
make it known.

Fn+Left (Auto brightness):
Apr 25 11:25:11 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x93 on isa0060/serio0).
Apr 25 11:25:11 snoogens kernel: atkbd.c: Use 'setkeycodes e013 <keycode>' to
make it known.

And another key.

Fn+F1 (Hibernate):
Apr 25 15:29:48 snoogens kernel: atkbd.c: Unknown key pressed (translated set 2,
code 0x8a on isa0060/serio0).
Apr 25 15:29:48 snoogens kernel: atkbd.c: Use 'setkeycodes e00a <keycode>' to
make it known.

Bastien. I think we are correct, hal-info would allow us to push these as fixes
very easily. I'm not able to hack on this for a few days (exams coming up) but
could you start to collect some DMI data and keys? I think we just need to match
on DMI vendor, rather than fine grained per-laptop matching.

We can fix this in very few lines of code IMO.

Very likely, but I'd rather hear from the kernel maintainers first. I wonder
whether this would be fixable at the kernel level rather than needing to add
this to userspace itself.

Comment 5 Bastien Nocera 2007-05-30 11:03:54 UTC

From:
http://thread.gmane.org/gmane.linux.kernel.input/1638

So we'd need to fix this in user-space, as it wouldn't be accepted in the kernel.

An example on how to implement it on a Dell Latitude D420:

Comment 7 Bastien Nocera 2007-08-20 12:44:22 UTC

Already done in git master of hal-info, closing.
