@Mathieu, upstream would like you to record the signals that the barcode sends so they can trigger the bug on their machines without having access to hardware (also useful for regression tests etc).
I've tried to outline the process for you below (let me know if any of the steps doesn't seem to work on your machine): 1. download the debugging utility by opening a terminal and running "wget http://people.freedesktop.org/~whot/evtest.c" 2. stop the X windowing system by first running the command "sudo /etc/init.d/gdm stop" 3. once in text mode, switch to a text based console by pressing CTRL-ALT-F1 4. login with your normal credentials 5. disconnect / unplug the barcode reader completely 6. run the command "find /dev/input/event*" 7. connect the barcode reader to the computer again 8. run the same command "find /dev/input/event*" once more 9. there should be exactly one device entry / line which is included in the second print out (that was not there the first time), this represents your barcode reader device and it should look something like "evtest" where X is some number. 11. compile the debugging utility by running "gcc evtest.c -o evtest" 12. run the debugging utility by running "./evtest /dev/input/eventX > output.txt" (Note: you should use the specific eventX entry for your device that you found using steps 1-4) 13. zap something with the barcode reader 14. press CTRL-C to terminate the evtest debugging utility 15. now the file output.txt should have a complete trace of all the input events that were sent by the barcode reader, the file should look somewhat similar to this: http://temp.minimum.se/b.txt 16. type "sudo reboot now", and attach the file you recorded to the bug report ** Changed in: xserver-xorg-input-evdev (Ubuntu) Status: Confirmed => Incomplete -- Barcode reader kill X on scan https://bugs.launchpad.net/bugs/370851 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
