It works, thank you :-) The current drm-intel-nightly also works for me, but I get massive tearing and blinking when moving windows around. I just noticed that although 60Hz now works fine, 30Hz stopped working. When setting the mode to 3840x2160@30Hz the screen stays blank and dmesg says the following: [drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe B FIFO underrun However, from my side I consider that to be a minor issue.

They are now attached. Hello Can you please confirm whether https://patchwork.freedesktop.org/patch/113642/ fixes the problem? Thanks, Paulo Reporter, please report as requested. We close if no feedback. As already noted, this issue has been fixed for me for some time. I'll mark this as resolved. |
