The Battery (F3), Keyboard Backlight(F6), and Eject(Not an F#) keys do not function, and throw an error in dmesg: dell-wmi: Unknown key 0 pressed The Keyboard Backlight still changes when F6 is pressed, but does not report an event in xev. Eject and Battery do nothing except report the error in dmesg, and do not produce an event in xev. There is a patch that resolves the issue, but it doesn't seem to be in upstream. Ubuntu seems to have this working correctly in 2.6.32 on Ubuntu 10.04, but it regresses in 10.10 on kernel 2.6.34 and 2.6.35, so I don't think the patch went upstream. Reproducible: Always Steps to Reproduce: 1. Press Eject Key, Keyboard Backlight Key, or Battery Key 2. Examine dmesg for error. Actual Results: Pressing the eject key, battery key, and keyboard backlight key produced the above error in dmesg (or /var/log/messages), and did not generate keypress events. Expected Results: dell-wmi.c interprets the keys and assigns them to keycodes for eject, battery, etc. There is a simple patch for this. It just needs to be applied to the kernel before it is compiled. The patch works on both versions of the gentoo-sources I tried (2.6.34-gentoo-r1 and 2.6.35-gentoo-r1), as well as ubuntu kernel sources and any vanilla kernel sources I have seen >= 2.6.32 that had dell-wmi.c. --- dell-wmi.c 2010-08-01 18:11:14.000000000 -0400 +++ ./drivers/platform/x86/dell-wmi.c 2010-08-17 23:11:18.597904666 -0400 @@ -221,7 +221,7 @@ return; } - if (dell_new_hk_type) + if (dell_new_hk_type || buffer_entry[1] == 0x0) reported_key = (int)buffer_entry[2]; else reported_key = (int)buffer_entry[1] & 0xffff;
