I looked a little bit more into this, and there seems to be a difference in whether I use /dev/ttyS0 /dev/input/wacom as the "Device" in the "InputDevice" section. /dev/input/wacom is a symlink to /dev/ttyS0, but maybe the driver doesn't realize that it it a collision if the different names are used.
I have tested with the attached xorg.conf where I have stripped away most of the stuff that was irrelevant for this bug. With Option "Device" "/dev/ttyS0" uncommented, X crashes already on startup (it keeps restarting for a while after boot). The screen flashes several times between general corrupted screen and black during this and finally stops in the courrupted state. With Option "Device" "/dev/input/wacom" X starts just fine. During the first X session VT switching works fine. At logout, though, the X-server crashes and when gdm comes up again the VTs are corrupted. They still work as I can run commands blindly, but after switching to a VT I cannot get the X-session back. Finally, when commenting out InputDevice "stylus" "SendCoreEvents" in the "ServerLayout" section, everything works fine no matter which line I use in the input device. I attach Xorg.0.log for each case, two for the case of /dev/input/wacom, since I don't always get a crash with a backtrace in the log for this case. Let me know if there is anything more I can test. ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/25265898/xorg.conf ** Attachment added: "Xorg.0.log.ttyS0" http://launchpadlibrarian.net/25265899/Xorg.0.log.ttyS0 ** Attachment added: "Xorg.0.log.NotInServerLayout" http://launchpadlibrarian.net/25265900/Xorg.0.log.NotInServerLayout ** Attachment added: "Xorg.0.log.input-wacom" http://launchpadlibrarian.net/25265901/Xorg.0.log.input-wacom ** Attachment added: "Xorg.0.log.input-wacom2" http://launchpadlibrarian.net/25265902/Xorg.0.log.input-wacom2 -- Xorg crashed with SIGSEGV in DeleteInputDeviceRequest() https://bugs.launchpad.net/bugs/358643 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
