Keyboard and Mouse are from Microsoft, but I have the same problem when I use a different Mouse (from Targus).
In System/Preferences/Keyboard-Preferences the model "Microsoft Wireless Multimedia Keyboard 1.0A" is selected although I have a "Microsoft Digital Multimedia Keyboard 1.0A". Problem also appears when a generic Layout is selected like "Generic 105-key". The log created by dmesg when plugging in the keyboard and the mouse says: [434902.522568] input: Microsoft Microsoft® Digital Media Keyboard as /devices/pci0000:00/0000:00:04.0/usb2/2-1/2-1:1.1/input/input18 [434902.523108] generic-usb 0003:045E:00B4.0011: input,hidraw1: USB HID v1.11 Device [Microsoft Microsoft® Digital Media Keyboard ] on usb-0000:00:04.0-1/input1 [434909.840039] usb 2-3: new low speed USB device using ohci_hcd and address 14 [434910.066175] input: Microsoft Microsoft 3-Button Mouse with IntelliEye(TM) as /devices/pci0000:00/0000:00:04.0/usb2/2-3/2-3:1.0/input/input19 [434910.066602] generic-usb 0003:045E:0040.0012: input,hidraw2: USB HID v1.10 Mouse [Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)] on usb-0000:00:04.0-3/input0 -- Keyboard special keys interfere with mouse https://bugs.launchpad.net/bugs/636311 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
