Created attachment 137221 [details] photo No display after idle for RX460 after upgrading to linux 4.15.1 distribution Arch. DC is not included, the problem on DP and HDMI. Also this problem even earlier, long ago, appeared on AMD Kaveri a10 7850k. P.S. monitor AOC G2260VWQ6
Please include your dmesg output and Xorg log if using X.
Does it work with DC enabled?
Created attachment 137222 [details] dmesg Attach dmesg
Created attachment 137223 [details] Xorg log Attach Xorg log. DC then turned, I'll watch the reaction.
dc1 + hdmi. The problem remained
Did you capture the Xorg log and dmesg before or after the problem occurred? If before, can you grab them again after? What was the last kernel version where this didn't happen?
After rebooting done due to this problem. Without the screen it is problematic to do, immediately after. 4.14.15-1

If you have another computer, you can do it via ssh. > 4.14.15-1 Any chance you can use git bisect to isolate the change between 4.14 and 4.15 which introduced the problem?
I will not be able to do, not enough skill. Tried to drag through TV files, TV breaks after the loss of the signal on the main machine. Also tried to register in the console dmesg creation with the switched-off screen, but nothing left. Perhaps there is a bug not with the video, and no signal from keyboard and mouse. Why not get out of standby.
Now on 4.15.3 - 2 problems already there. The problem is not relevant.
The kernel update didn't fix the problem, I thought. But now I know what the bug is about. This happens when you enable vertical sync in the settings of xfce.
Does this problem also happen using xf86-video-amdgpu instead of the modesetting driver with Xorg?
In the case of option tearfree on came out of sleep. But there was a bug that flew in resolution 1366x768 and 1080p was not available. But it is possible problems xfce4, or I config the curve did. I have there Section "Screen" Identifier "Screen" DefaultDepth 24 SubSection "Display" Depth 24 EndSubSection EndSection option tearfree on
Because "tearfree true" is also not loaded Arch further, it literally immediately after removing the line. The problem is a bit similar.
TearFree works, I did the configuration file wrong. Problems if the string is entered after "EndSection". P.S. But with the inclusion of regular V-sync xorg, still problems even with the latest xf86-amgpu.
