It sounds like "nomodeset" is actually causing the newest error: no UMS support in Radeon module
That's expected with nomodeset and probably not a bug. So we should instead find out why you had a hang with only a cursor at the top left of the screen. Please: 1. Remove "nomodeset". 2. Reboot (expecting it to fail). 3. Reboot again with "nomodeset" and run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. ** Summary changed: - AMD HD7970 Error: no ums support in radeon modual + After installation it just hangs with a cursor at the top left of the screen ** Package changed: gnome-shell (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1968428 Title: After installation it just hangs with a cursor at the top left of the screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1968428/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
