            Bug ID: 90987
           Summary: xorg black screen after monitor power off, AMD r9
                    270X, aoc u2868pqu, displayport
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
          Assignee: xorg-driver-ati at lists.x.org

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
GNU/Linux


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 "



[drm:radeon_dp_link_train [radeon]] *ERROR* displayport link status failed
