[Bug 1881390] Re: amdgpu.dc=0 required for gui display
apport information ** Tags added: apport-collected ** Description changed: I have Ubuntu 18.04 on my system. When I boot, I get a black screen once mode switching happens. Rescue mode (aka nomodeswitch) would bring me to a gui screen correctly. I tried backing off to X.org from Wayland, but that didn't help. I eventually found an obscure post suggesting adding amdgpu.dc=0 to the command line. With this added, I have the GUI I expect. Originally the system worked as expected, but something changed which required this setting. The graphics card is an AMD RX480.

I followed the instructions to change to confirmed. But the kernel from proposed, as well as the mainline one I have up at the moment, work correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881390 Title: amdgpu.dc=0 required for gui display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, I have my gui back without amdgpu.dc=0.

amdgpu.dc=0 gets me a gui with X.org. With Xwayland, I still get a blank screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881390 Title: amdgpu.dc=0 required for gui display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-hwe/+bug/1881390/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
