Of course you're allowed to use any driver you like. We just can't accept bug reports on this site when the driver isn't from Ubuntu.
I suggest the way forward here is to remove the driver completely, reboot and prove the same bug happens with the default driver. Then log a new bug from the machine while it's in that state. Then reinstall your preferred driver if the default driver isn't suitable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2102492 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2102492/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
