Hi, I'm seeing this error as well. The last frame shown while logging in freezes on the second monitor and only the cursor updates.
I have enabled iGPU Multi-Monitor for my ASUS motherboard, which enabled me to connect one monitor through the motherboard and one through my GPU - the one connected to the GPU is the one that freezes. This has previously worked with Ubuntu 18.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792822 Title: Dual monitor not working in 18.04(.1) on a dual-radeon-GPU system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1792822/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
