[Bug 107978] [amdgpu] Switching to tty fails with DisplayPort monitor going to sleep (REG_WAIT timeout / dce110_stream_encoder_dp_blank)
https://bugs.freedesktop.org/show_bug.cgi?id=107978 --- Comment #10 from Shmerl --- I just found something. My monitor - Dell U2413 has a setting for toggling DisplayPort 1.2. It was enabled until now. When I disable that setting, tty starts working! My cable is supposed to support DP 1.2 and be Vesa compliant. It's Accel UltraAV DP 1.2 cable. I hope this can help narrow down the problem. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=107978 --- Comment #9 from Shmerl --- By the way, I tested it with this kernel: https://github.com/M-Bab/linux-kernel-amdgpu-binaries/blob/master/linux-image-4.19.0-rc6_18.09.30.amdgpu_amd64.deb Which is built from AMD's tree. This issue is also present in it. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=107978 --- Comment #7 from Shmerl --- I'm using KDE Plasma 5.13.5, current Debian testing x86_64. Can you try it with Debian? Ubuntu stack is not that close anymore. I also noticed one detail. When screen mode is chaning (like before sddm comes up), the monitor goes to sleep briefly and then wakes up. That wasn't happening before and it's not a correct behavior. In 4.18 it wasn't waking up at all, and it was fixed in 4.19. Similar thing is happening during switch to tty (screen mode is changing indicated by the DP monitor icon appearing), except the monitor isn't waking up anymore. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

Do you mind posting a full dmesg log with drm.debug=4 and an xorg log? It would also help to know what desktop environment you're using. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=107978 --- Comment #3 from Shmerl --- Is this issue Debian specific or anyone observed it in other distros? Because if it's something wrong with Debian's kernel build I should probably file a Debian bug about it. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
