Hi Jonathan, Thanks for trying the multiseat stuff. I haven't tried Debian 5.0, but if you're not getting anything at all in /dev/usbseat, it seems like the 50-usbseat.rules are not getting executed at all. Are the .rules files in the same location on Debian 5.0? Do the permissions and ownership match those of the other .rules? There have been some small udev syntax changes in the past, but all recent distros should be the same. I'd look first for something major out of place (perhaps the point of the hang). On that, try disabling the use of the displaylink device as a text console: via <a href="http://libdlo.freedesktop.org/wiki/TextConsole">http://libdlo.freedesktop.org/wiki/TextConsole</a> or some better method. Perhaps also try testing the rules independently: <a href="http://reactivated.net/writing_udev_rules.html#testing">http://reactivated.net/writing_udev_rules.html#testing</a> Won't help this problem, but I'll have some small simplifications to <a href="http://libdlo.freedesktop.org/wiki/MultiSeatTerminal">http://libdlo.freedesktop.org/wiki/MultiSeatTerminal</a> shortly. Also, the xrandr -o 0 workaround is essential for getting multiseat on Ubuntu 9.04 is working better (but still has some other problems vs. Ubuntu 8.10, e.g. input events getting reflected to the console). Thanks for reporting back (or adding to the libdlo wiki) any solutions you find! Thanks, Bernie <div class="gmail_quote">On Tue, Sep 15, 2009 at 5:54 AM, Jonathan D.

The "hard" part seems to work. I have the fb module and xorg driver built and I get a text terminal and can manually start X on the DisplayLink device. But it seems there something not right with /etc/udev/rules.d/50-usbseat.rules I have the Display link, keyboard and mouse plugged into a powered USB2 hub (with nothing else on that hub) but I don't get anything in /dev/usbseat, infact I don't even get a /dev/usbseat. Not quite sure what to look for, while I'm not terribly familiar with udev, it seems pretty simple: # aliases for display, kbd, mouse attached to specific hubs KERNEL=="fb*",SUBSYSTEMS=="usb",PROGRAM="/bin/cat /sys/%p/../../../devnum",SYMLINK+="usbseat/%c/display" KERNEL=="mouse*", SUBSYSTEMS=="usb", ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="02", PROGRAM="/bin/cat /sys/%p/../../../../../devnum",SYMLINK+="usbseat/%c/mouse" KERNEL=="event*", SUBSYSTEM=="input", ATTRS{bInterfaceClass}=="03", ATTRS{bInterfaceProtocol}=="01",PROGRAM="/bin/cat /sys/%p/../../../../../devnum",SYMLINK+="usbseat/%c/keyboard" Also if I reboot with the display link attached, the boot process hangs sometime _after_ switching the console to the displaylink device. Sorry didn't quite catch what it was trying to do, so don't expect much enlightenment on this point.
