I reproduce the bug with the 5.4.0-49-generic kernel from `proposed` when running the Radeon X1950 PRO.
Note: I previously joined a dmesg log file about GPU lockup, such lockup is not always logged but the GNOME Shell session is stuck anytime it is started. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899304 Title: Linux 5.4.0-48 causes GPU lockup, huge performance drop, makes GNOME desktop fail to start and games going from 70fps to 7fps, slow file loading, audio issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899304/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
