I've added a screenshot (screen photo) of the GNOME desktop being stuck and unresponsive while running the ATI Radeon 4350 PCI on the K8 AGP host.
You'll notice this is the exact same symptom I get with ATI Radeon AGP cards on this host starting with kernel 5.4.0-48-generic and later (while that AGP card worked flawlessly on 5.4.0-47-generic), see #1899304 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899304 On the K8 PCie host, the display goes off immediately at kernel launch, right after GRUB launches it, so there is absolutely nothing to see. If I'm right, the lockup is so hard the system does not run in background and I cannot connect through SSH (right, this is the same symptom I get with the Nvidia PCI card). I don't have access to recent enough (GL 3) Nvidia AGP cards to compare symptoms with that GL 3 Nvidia PCI card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902795 Title: PCI graphics seems to be broken since years on AMD K8/K10 platform (work on Intel) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1902795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
