I saw this error from dell-wmi also. The system is a Lattitude e6400 and the "unknown WMI event" happened repeatedly (a dozen times) overnight.
Doing a Fn+F8 (which changed the video from two screens to one screen to a duplicate screen back to two screens again) I got these errors: Apr 1 09:30:23 winry kernel: [260556.557580] Skipping EDID probe due to cached edid Apr 1 09:30:23 winry kernel: [260557.230789] Skipping EDID probe due to cached edid Apr 1 09:30:24 winry kernel: [260558.266557] dell-wmi: Received unknown WMI event (0x11) Sometimes the "Skipping EDID" error was double, mostly just singles entries before each unknown WMI event. The system is studiously kept up to date and is Ubuntu 10.10: $ uname -a Linux winry 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:40:58 UTC 2011 i686 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/581312 Title: Unknown key fee[x] pressed with Dell Latitude XT2 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
