Description Julian Sikorski 2008-12-16 12:14:37 UTC

Latest working kernel version: none
Earliest failing kernel version: it never “just worked”
Distribution: Fedora 10
Hardware Environment: Toshiba Satellite A100-847 with a Logitech Alto Cordless keyboard
Software Environment: 
Problem Description:
Originally reported to Red Hat bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=473908
This laptop stand/cordless keyboard mix emits wrong scancodes for Fn-F3 and Fn-F4. I believe this should be fixed in kernel, so that the standard evdev keymap works out-of-the-box.
This is what gets reported by evtest:
Event: time 1228294575.277680, type 4 (Misc), code 4 (ScanCode), value c0223
Event: time 1228294575.277708, type 1 (Key), code 172 (HomePage), value 1

HomePage is emitted upon Fn-F3, and Config upon Fn-F4. These get translated by X to XF86Home and XF86Tools, respectively. I believe that the proper translations would be XF86WWW (since there is MSIE icon on that button) and XF86AudioMedia (a music note). I'm not sure what these correspond to kernel-wise.

Steps to reproduce:
1. Plug in a Logitech Alto Cordless keyboard
2. Press Fn-F3
3. Press Fn-F4

Created attachment 19329 [details]
dmesg output, fn-f3 and fn-f4 were pressed, among other necessary keys

Attaching the dmesg output, hopefully it contains the required information.

Closing as obsolete, please re-open if this is present in a modern kernel
