I have tried the most recent kernel 5.12-rc8 to complete the information needed for further investigation. The results are about the same as for the previously tested 5.8.0-* & 5.11.8-051108, i.e.:
ACP disabled - Xorg amdgpu driver loaded & acceleration working - suspend/resume ok - hibernation fails (hibernation image not created, PC seems to freeze but does not shut down, hard reset needed) ACP enabled - I get black screen, Xorg fails to start, PC unresponsive - suspend/hibernation cannot be tested Is there any other information I can/should provide? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920674 Title: AMD A8-7680 (amdgpu): broken Xorg acceleration and hibernation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1920674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
