Thanks, I can see a clear crash from comment #7: Xwayland: ../nouveau/pushbuf.c:723: nouveau_pushbuf_data: Assertion `kref' failed. It's being tracked in bug 1497593. But it should not happen again now that you have installed the NVIDIA driver. ** This bug has been marked a duplicate of bug 1497593 [nouveau] Programs crash with SIGABRT in nouveau_pushbuf_data: Assertion `kref' failed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931387 Title: Ubuntu UI screen image freezes randomly during usage after fresh 21.04 install, suspecting Wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1931387/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
