Bug 1314923

Created attachment 1158506 [details]
xorg.0.log

Attached is my xorg.0.log once booted using x server instead of wayland.

The benq monitor listed in there was my old DVI monitor which has not been used in a while.

The new monitor is HDMI.

It does not seem that the monitor (while in use) is being detected. Is there any command I can run that would provide useful output?

This happens starting from kernel 4.6, 4.5 works fine.

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

I am not sure about the comment above that states this only started with Kernel 4.5.

I have just tested on a Fedora 23 Live USB (Kernel 4.2) and the issue is the same.

The issue persisted in Fedora 24 from start to last update and n Fedora 25 with latest updates.

The monitor in the Display settings is listed as  Goldstar 34" monitor with a 1080p resolution.

However in the Color tab in the control panel, it is listed as an LG ULTRAWIDE Monitor.

Connection is via HDMI.

Sounds like that EDID is not parsed properly.

*** Bug 1292883 has been marked as a duplicate of this bug. ***

The problem may come from the DisplayPort / HDMI adaptor: https://communities.intel.com/thread/102059

How can I help test this?

The HDMI port works correctly on Windows (I am dual booting on this PC).

(THe Benq details in the previous xorg log was for my previous monitor. I do not know why those details have persisted as I had stopped using it prior to this).

As a work around, you can just run the following commands to be able to use the native resolution:

xrandr --newmode "2560x1080_60.00" 230.76 2560 2728 3000 3440 1080 1081 1084 1118 -HSync +Vsync
xrandr --addmode HDMI1 "2560x1080_60.00"
xrandr --output HDMI1 --mode "2560x1080_60.00"

In wayland (after changing HDMI1 to XWAYLAND0), nothing happened (probably expected?)

Using Gnome on X11 (changing HDMI1 to HDMI-0), the monitor could not display the output.

There were a couple of flickers, some screen distortion where it tried to display the picture as 1920x1080, but this failed.

In my company we have the same screens, and the same issue.

On Fedora 25 (yesterday) the workaround suggested by Gonéri Le Bouder did nothing. Today, when I try it on Fedora 26 weird things are happening: flashing, switching off the external screen, even displaying picture on built-in screen with backlight switched off and claiming that this screen is not in use (according to gnome screen dialog on the second screen).

If that matters, I have a Dell Latitude E6330 with docking station and connect that screen by DisplayPort-Adapter-HDMI or DVI-HDMI cable.

Everything worked fine in some older Fedora release (I can run it again from pendrive if that helps).

I have no idea how to fix that, but I am willing to provide any logs you need and reproduce the issue any time.

Since last report I have upgraded the graphics card to a Radeon RX460. With this the 2560x1080 resolution is detected and used by default but it gives a mangled video output.

I have recorded a video a video showing the problem:

https://www.youtube.com/watch?v=SFr-i2LyWXA

I have now tried changing the cable just in case the issue was with the cable but the new (hdmi 2.0 capable) cable shows the same results.

Testing with a Displyport to HDMI cable, the issue remains, so it is not a HDMI timing issue that some google results suggested may be the cause

The issue persists in Fedora 28 (upgrade, not new install).

Updated Edid-decode with linux kernel 4.16 on Fedora 28:

With kernel 4.17 things have gotten worse and I have made a separate big report: https://bugzilla.redhat.com/show_bug.cgi?id=1594488.

After today's experimentation, I think the issues are atleast linked.

Symptoms prior to Kernel 4.17: garbled output at full resolution.
Symptoms post 4.17: no screen output at all (blank screen).

Hi,

I don't have any problem when I use my Lenovo docks (T450s and T580). So I my case, it was a limitation of the HW.

This message is a reminder that Fedora 28 is nearing its end of life.
On 2019-May-28 Fedora will stop maintaining and issuing updates for
Fedora 28. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora 'version' of '28'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 28 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Thanks for saving me!

Paul (on rhel7 or else I would re-open the bug :)

Hello Paul, 

Are you able to use this monitor/resolution in recent Fedora versions running Wayland? (eg. 32)

I am facing a similar issue: https://bugzilla.redhat.com/show_bug.cgi?id=1883263

Thanks

Mario
