I've roughed up a page on debugging client XErrors since these seems to be a pretty common class of error, and we didn't seem to already have a good knowledgebase for people on how to deal with them: https://wiki.ubuntu.com/X/Troubleshooting/XError It would be majorly helpful if you guys could flesh that out further since you all probably have more experience with the tricks of debugging these kinds of issues. -- [MASTER] Gdk-ERROR **: The program 'firefox-3.5' received an X Window System error (BadWindow) https://bugs.launchpad.net/bugs/401055 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
