Thanks for those links, I have done a bit of investigating, the behaviour seems to be linked to this message I am getting in the xorg log:-
[ 0.145343] (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled. [ 0.145349] (WW) Disabling Keyboard [ 0.145355] (WW) Disabling Mouse For a test I set AllowEmptyInput to FALSE, this re-enabled the keyboard mouse and LED's. However..... A bug I previously logged and then found fixed with Jaunty regarding the LED's being linked is now a problem again:- https://bugs.launchpad.net/ubuntu/+bug/300974 Also it seemed that every time I did a ctrl-c the whole X server reset/crashed, so I have reverted the setting for the moment and I am using a panel applet to inform users of the led status. -- Update seems to have stopped Xorg talking to mouse and keyboard in Multiseat https://bugs.launchpad.net/bugs/335802 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
