<pre>xorg black screen after monitor power off, AMD r9 270X, aoc u2868pqu,
displayport
please let me know how I might gather better info
when the monitor goes into power save mode or I power it off manually for a few
minutes xorg goes completely black.
I can switch to other TTYs; can even start a second xorg from there
When I try to switch back to the original TTY that xorg's still black.
these messages show up on the second TTY
[34181.758006] [drm:si_dpm_set_power_state [radeon]] *ERROR*
si_restrict_performance_levels_before_switch failed
[34181.835519] [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link
status failed
[34181.835526] [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery

[34181.838937] [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link
status failed
[34181.838942] [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery
failed
nothing looks relevant to that error in
~/.local/share/xorg/*
these messages also show up if I turn off the monitor when positioned on a
console, but the console is still accessible on monitor power up.
none of these show up if I turn off the monitor when positioned on a KMScon,
and the KMScon is still accessible on monitor power up.
here's my kerrel info:
Linux samain 4.0.4-2-ARCH #1 SMP PREEMPT Fri May 22 03:05:23 UTC 2015 x86_64

when this started one thing I tried was changing the kernel command line
GRUB_CMDLINE_LINUX_DEFAULT=" md_mod.start_ro=1 radeon.audio=1 radeon.dpm=0 "
