Hey guys, "gdm_slave_xioerror_handler: Fatal X error - Restarting :0" is a generic error message (like "out of memory" or "syntax error") and can be caused by a myriad of different things. Indeed, it's quite likely each of your issues is due to a separate, unrelated problem (especially given how some people resolved it by not using software A, others notice it with software B, etc.) The underlying problem might be a bug in a driver, or it could be due to a software program doing something unexpected to X.
In any case, X crashes are straightforward (if a bit of work) to debug. There is a fairly good document describing the steps to take here, which I would strongly encourage going through: https://wiki.ubuntu.com/DebuggingXorg Obviously, being able to recreate the problem is half the battle. "X crashes randomly" are quite tough to deal with. But a technique is to install all the relevant dbg packages, and then ssh into your system from a second machine, and run Xorg from within gdb, and then go about your business. When a crash does occur, go to the 2nd machine and use the directions above to get a full backtrace. (Note that if the system locks so badly that you can't do this, then you may have a kernel issue.) If you've not used gdb before, it may seem a bit daunting at first, but there's only a few steps you need to do, and it's a skill you can reuse when you run into other software that crashes. The good news is, once you have a full backtrace with proper debug symbols, we can forward these bugs upstream almost immediately. In addition, since I suspect that everyone's error is independent, when you do this please file a new bug report. In addition to the backtrace, include the usual files (Xorg.0.log, xorg.conf, and the output of lspci -vvnn). I am going to retitle and refocus this bug report to only the original reporter's issue. -- X crashes on RV370 with firefox + gnash visiting certain urls (no desktop effects) https://bugs.launchpad.net/bugs/140554 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
