I made another attempt with a kernel from https://kernel.ubuntu.com /~kernel-ppa/mainline/v5.7/
The dmesg looks slightly different. But I think, that the bug behaves a little different every time. Sometimes I just get a black screen, sometimes the picture freezes and sometimes I can still move the mouse cursor over the frozen picture. ** Attachment added: "dmesg with kernel 5.7" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1881494/+attachment/5379977/+files/linux-5.7_gnome_dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881494 Title: [amdgpu] suspend to ram (standby) crashes amdgpu (Ryzen-7 Vega - HP Envy x360) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
