I'm confused. The upstream commit is included in version 1.3.0, which is in 10.04 and later. So if you still have crashes, they might be something else and thus deserve a bug of it's own.

[Ubuntu-x-swat] [Bug 355021] Re: Unplugging USB tablet crashes xserver (Jaunty)
This bug is also present in Arch Linux current, with xf86-input-aiptek 1.2.0 and xorg-server 1.6.1. These packages are unpatched, so it is almost certain that this is an upstream problem. There has not been any commits to the aiptek driver git repo after 1.2.0 Some information I've gathered (likely not very useful, but included here just in case): - The error seems to occur when the aiptek driver is removed: rmmod aiptek with the device plugged in produces this bug. When it is not connected, modprobe aiptek rmmod aiptek works as expected; no crash. - Removing the device is removed while hal is not running (in the middle of restarting hal for instance), it doesnt crash. Likely because the driver doesnt get removed. I will produce a backtraces, dmesg and lsusb on a jaunty system shortly and add them here. -- Unplugging USB tablet crashes xserver (Jaunty) https://bugs.launchpad.net/bugs/355021 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-aiptek in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

There are some stack frames that still miss proper function names, for example there is: #12 0xb7f22749 in ?? () from /usr/lib/libhal.so.1 to get a proper function name for that one you need to install debug symbols for the package that ships the file /usr/lib/libhal.so.1 and to find out which package that is you need to run dpkg -S /usr/lib/libhal.so.1 (in this case the package is libhal1 so you need libhal1-dbgsym. Seems you also need symbols for /lib/libdbus-1.so.3 which means libdbus-1-3-dbgsym.

[Ubuntu-x-swat] [Bug 355021] Re: Unplugging USB tablet crashes xserver (Jaunty)
btw, this also explains why the apport crash reporter didn't detect the crash. It's not actually a traditional segmentation fault, instead it's a consistency check in the C library that notices that something is not right and then abort the program. One thing that perplexes me about this backtrace is that Xfree(NULL) seems to call free(non_NULL_value), i.e. this part: #5 0xb7c155b6 in *__GI___libc_free (mem=0x953c9c8) at malloc.c:3625 ar_ptr = (mstate) 0xb7d04140 p = (mchunkptr) 0x953c9c0 hook = (void (*)(void *, const void *)) 0x6 #6 0x08139021 in Xfree (ptr=0x0) at ../../os/utils.c:1165 No locals. I've have no explanation of how the above could possibly make sense (except maybe its some weird gcc optimization but if I said that I would be in the longshot guess department) ... let's ignore it for now. Moving on, since this is a double free it owuld be interesting to see if the xf86AiptekUninit function is called multiple times with the same pointer value. Getting full backtraces of both of these calls would be useful. Especially since the weird Xfree() happens to call libc_free() with the exact same pointer value as the one pass to xf86AiptekUninit() in stackframe #8. Once you have captured the full backtrace as I asked in the previous comment (I think it's still nice to have this when we upstream the bug report). Can you then try to put breakpoints on the functions xf86DeleteInput(), xf86AiptekUninit() and DeleteInputDeviceRequest() and then re-trigger the bug by disconnecting the tablet. Then please record a backtrace full every single time you hit a breakpoint and paste the log here again. You can activate logging to a file using the command set logging file aiptek_gdb_log.txt followed by the command set logging on.

@Neil, can you please start the automatic crasher reporter and then trigger the bug? This will hopefully give us a full backtrace showing exactly where in the X server the crash happens. To start the crash reporter run this command: sudo force_start=1 /etc/init.d/apport start ...afterwards just unplug the tablet to trigger the crash. When you login again, just wait like 1-2 minutes and there should be a dialog saying that a crash was detected, would you like to submit a bug report? so similar. Press SUBMIT and let it open a new bug report (then mark that new bug report as a duplicate of this one so we can grab the full backtrace from the logs in that report). Also, please attach the output of lsusb -v to the bug report (run the command with the tablet connected). And finally it would also be nice if you saved the output of the dmesg command recorded after you have first triggered the crash /by unplugging), and then logged in again and then re-connected the tablet. ** Changed in: xserver-xorg-input-aiptek (Ubuntu) Status: New = Incomplete -- Unplugging USB tablet crashes xserver (Jaunty) https://bugs.launchpad.net/bugs/355021 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-aiptek in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
