I've carried out the requested checks and the result files are attached. I've since discovered that the keyboard fault is only present when the mouse is connected via the KVM switch. If I connect the mouse directly, the keyboard is OK. However, the video problem occurs irrespective of how the mouse is connected.
The bugzilla 4564 may be related but is not identical. My problem occurs from boot up - it appears that 4564 occurs only after changing the KVM. ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/16701255/dmesg.log -- Wont' work with KVM switch https://bugs.launchpad.net/bugs/176326 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
