Thanks. It sounds like Xorg is not smart enough to use the debug symbols. Your latest crashes on errors.ubuntu.com still show the robots are ignoring crashes from this machine. I don't know the reasons but can only guess something has changed during the upgrade process. And so the only suggestion I have right now is to reinstall from scratch if you want automated crash retracing to work.
Other weirdness in your crash reports on errors.ubuntu.com: JournalErrors -- No entries -- So there is no system log being collected either. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/2001922 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/2001922/+subscriptions _______________________________________________ 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
