bugzilla kernel 4564 Anyway it seems to be a problem of ps/2 protocol between de KVM and the MB of your system according to what i've found. Try putting any of this parameters at the end off kernel boot line psmouse.proto=exps or psmouse.proto=bare or psmouse.proto=imps Also you can try unloading the psmouse module and reloading with this parameters proto=imps resync_time=10 try using the different protocols. Also to get the most information let's get this output as root: - "echo 1 > /sys/modules/i8042/parameters/debug" - switch to your other box - wait 5 seconds - switch back to linux box - Press left mouse button once - "echo 0 > /sys/modules/i8042/parameters/debug" - upload dmesg About the video issue i believe we would need a different bug report for that one. in the meantime i'm marking this related to upstream bug 2082 and 4564. Not exactly the same but similar enough. ** Changed in: xserver-xorg-input-mouse (Ubuntu) Sourcepackagename: None => xserver-xorg-input-mouse Assignee: SEAQ - Andres Mujica (andres-mujica) => (unassigned) Status: Incomplete => Confirmed ** Changed in: xserver-xorg-input-keyboard (Ubuntu) Status: New => Confirmed ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Bug watch added: Linux Kernel Bug Tracker #2082 http://bugzilla.kernel.org/show_bug.cgi?id=2082 ** Also affects: linux via http://bugzilla.kernel.org/show_bug.cgi?id=2082 Importance: Unknown Status: Unknown -- 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
