[Bug 599781] Re: X crashes when reconnecting USB devices via a KVM switch
Henri Sivonen, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command in the development release from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux replace-with-bug-number Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Tags removed: crash hardy ** Tags added: needs-upstream-testing regression-release ** Description changed: Binary package hint: xorg I upgraded from Karmic to Lucid (64-bit). Previously with Karmic, I have been able to disconnect and reconnect my USB input devices (Kinesis Advantage USB keyboard and Wacom Graphire 2 tablet connected to an Apple Cinema Display connected to a Belkin KVM switch) by using the KVM switch. Now with Lucid, switching the USB devices back to the Ubuntu box sometimes crashes X when the Wacom tablet is detected. Details: * The KVM switch identifies itself as No brand Combo Free KVM - 10d5:5000 Uni Class Technology Co., Ltd * The KVM switch has dedicated ports for mouse and keyboard for the purpose of faking the continuous presence of the mouse and keyboard to two computers. That function of the KVM switch doesn't work, so I have instead connected my input devices to a USB hub port of the KVM switch. Using this port is equivalent to disconnecting and reconnecting the USB devices when the KVM switch toggles between computers. * Typically, after reconnecting the Wacom tablet, it takes a couple of seconds for the LED on the tablet to light up and the tablet to become operational. This means I have a couple of seconds to see X when switching back to the Ubuntu box and X dies when the LED on the tablet lights up. * Once X dies, I see the kind of text briefly that one would sometimes see when shutting down a Ubuntu Live system. Then I'm taken back to the login screen. * If I switch back and forth quickly in order to provoke the problem, it doesn't happen. It seems to happen when the USB devices have been disconnected at least a couple of minutes before reconnecting. * If I press keys on the keyboard and/or try to tap the tablet with the tip of the stylus after connecting the devices but before the LED on the wacom tablet lights up, the crash is more probable.

Why has this been assigned to xserver-xorg-video-openchrome?
