            Bug ID: 105046
           Summary: Screen resolution reset to 1368x768 when turning
                    monitor off
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: forums18@mizapf.de

With amdgpu.dc=1, when I turn off the monitor or the monitor enters power-save
state, the screen resolution changes to 1368x768, which messes up the desktop
elements arrangement. Opening the settings, it is the highest offered
resolution, and the original resolution can only be restored by killing X or
rebooting.

This effectively means that I have to keep my monitor running till logout.

It happens on three different systems, all using amdgpu (RX480, RX580, RX460).

Does not happen with amdgpu.dc=0.

What monitor do you use and is it connected via DisplayPort, HDMI, or DVI?

I got 3 systems where this issue occurs:

1. Monitor HP LP2475w connected via HDMI through a Pioneer AV receiver
(VSX-330) to an AMD Radeon RX480. (New DC was needed to get HDMI Audio.)

2. Similar monitor, directly connected via HDMI to AMD RX 580

3. UHD monitor, connected via DisplayPort to a RX 460.

I'm sitting at 1., can add more information to 2. and 3. when I return to my
second apartment resp. my office tomorrow.

Can you attach a full dmesg log from boot until this issue occurs, with kernel
options amdgpu.dc_log=1 and drm.debug=6?

Can you also paste what 'xrandr' outputs before and after this happens?

I wonder if EDID read fails for whatever reason.

dmesg output after turning the monitor back on (2nd system)

This is another dmesg output, created on my office PC with a UHD display,
connected by DisplayPort.

The turn-off event occurs after time [2643.173460]. Turn-on occurs some seconds
later.

System was updated the same day in the morning (openSUSE Tumbleweed rolling
release, 4.15.2-1).

Is there at least some way to restore the real monitor resolution without
killing the Xserver (and hence all running desktop applications)?

Right now I either have to reboot, or I must turn off the monitor, then kill
the Xserver (ctrl-alt-bs), then turn on the monitor again. It does not even
suffice to kill the Xserver alone.

Unplugging and replugging the display should get you back to normal.

Unfortunately, that does not work, I just tried it. I suppose that otherwise,
turning the monitor off and on should have already helped.

The only way to restore leads me via killing the Xserver. Maybe some xrandr
command? It needs to refresh its resolution list, though.

There may be some influence by the A/V receiver in the chain, but as I posted
on Feb 15, the effect is also there with my UHD monitor in the office,
connected by DisplayPort, and having nothing in between.

It seems to be related to EDID, as I see it.

Once I turn off the display, I lose the EDID information.

When I continue to turn it off and on again, EDID does not reappear. However,
when I reboot, it is there again. How does my monitor know that my PC has been
rebooted?

I solved the same problem for me a long time ago by adding a
"drm_kms_helper.edid_firmware=edid/my_monitor_model_edid.bin" option to my
kernel command line, after saving the EDID blob of my monitor to the given
file.

But sure, would be great if such wasn't necessary.

I've got the same issue with an AMD Ryzen 5 2400G after a power cycle of the
monitor (Dell U3011 with a resolution of 2560x1600 connected via DisplayPort).
It happened not always, but very often. I thought, it was fixed by the
workaround with the "drm.edid_firmware=..." kernel parameter, but now it
happened again. And there also seems to be a crash in the amdgpu driver. I've
attached the dmesg output after this happened.

--- Comment #14 from Michael Zapf <forums18@mizapf.de> ---
Anything new? The problem is still there, although now it falls back to a
higher resolution (1920x1080), still causing a mess on my desktop.

I would like to emphasize that this issue does not appear with amdgpu.dc=0. I
tested it several times to make sure.

I tried it with an own EDID file; picked it from the xrandr, then saved it to a
file /lib/firmware/edid/mizapfmon.bin. Then I added a kernel parameter
"drm.edid_firmware=edid/mizapfmon.bin". (drm_kms_helper is deprecated)

During boot:
Aug 12 01:07:08 capella kernel: platform HDMI-A-2: Direct firmware load for
edid/mizapfmon.bin failed with error -2
Aug 12 01:07:08 capella kernel: [drm:drm_load_edid_firmware [drm]] *ERROR*
Requesting EDID firmware "edid/mizapfmon.bin" failed (err=-2)

I don't know whether something is missing, maybe I have to add the firmware to
the initrd. But it is not required at boot time; the screen is OK at that time.

When I turn the monitor off and on again, I'm getting the following lines in
/var/log/messages, and the screen resolution is again reset to 1920x1080.

[Bug 105046] Screen resolution reset to 1368x768 when turning monitor off

Hi Michael,

in order to work at boot time, you have to add your edid file to your initrd or
initramfs. Don't know, what distribution you are using, but if it uses dracut,
then you should create a file /etc/dracut.conf.d/99-edid.conf (the filename is
arbitrary, but it must have the suffix ".conf") with the following content:

install_items+=" /lib/firmware/edid/mizapfmon.bin "

and then run mkinitrd.

But as I've said, this didn't fix the issue for me.

Lothar

That is, there is no EDID data anymore.

---

I was looking for some tool to read the EDID channel, but I was not yet
successful. I am using openSUSE. I tried to download and compile read-edid, but
I get an error message from cmake about a missing setting of X86_LIBRARY.

Then I found a python tool on Github (edid-rw), but I cannot find the smbus
python module (not in the repositories).

Just installed openSUSE with kernel 4.18; the issue seems to be fixed! Let me
check with my office PC (in about a week) before declaring it resolved.

--- Comment #18 from Lothar Paltins <lopa@mailbox.org> ---
Unfortunately, the issue isn't fixed with kernel 4.18. I've also upgraded my
OpenSuse Tumbleweed, but the behavior is the same as before. The screen
resolution is correct after switching the monitor off and on about 4-5 times,
but it's wrong again after the next power cycle.

My workaround is to execute 

  xset dpms force off

instead of pressing the power key of the monitor. But sometimes even this
doesn't work. It only happens very seldom, but then the screen is only
partially blanked and the monitor doesn't go into power save mode. I have to
execute the xset command again to make it work.

On my office PC with 4K monitor, the issue is now also gone. That is, I have no
more evidence of that resolution reset on any of my computers.
