            Bug ID: 110862
           Summary: Dual-monitors invalid state after turning on
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: denisgolovan@yandex.ru

Hi

I experience annoying bug when I turn on my dual-monitor PC after some time is
turned off state.
Basically it results in following:

+-----------+
|   OK      |
|           |
+-----------+------------------+
|           |                  |
|           |                  |
| GARBAGE   |  GARBAGE         |
|           |                  |
|           +------------------+
|           |
|           |
+-----------+

X Windows render a small part of screen ("OK" area), everything else is
garbage, quite often flicking. Changing VT does not help.

Tested under Linux x64 5.1.6 + xorg-server-1.20.5 + amdgpu driver from git.
Hardware: XFX RX580 8GB

Please attach the corresponding Xorg log file and output of xrandr and dmesg.

Probably best if you attach all of those from a bad and good boot each.

--- Comment #8 from Michel Dänzer <michel@daenzer.net> ---
The xrandr output is probably different in the bad case as well, isn't it?

>From the bad case Xorg log file:

 [421376.800] (II) AMDGPU(0): Allocate new frame buffer 2160x738

This means Xorg calls into the driver to resize the desktop to 2160x738 (which
explains why that area is OK, whereas the remaining area has undefined
contents). This is most likely in turn due to a client (probably some component
of the desktop environment you're using) requesting so via the RandR extension.
So it's either a bug in that or in the X server, not in the driver.
