--- Comment #3 from Alex Deucher <alexdeucher at gmail.com> --- Does forcing a dpms cycle also work? E.g., sleep 5; xset dpms force off Does turning the monitor off work with other drivers or OSes? DP requires link training to bring the link up between the monitor and the GPU. I suspect when you physically turn off/on the monitor, it does not generate a hotplug signal so the driver had no way of knowing that the link needs to be re-established. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
