DisplayPort no longer working after latest update

Support Graphics & Display
1

I have two displays connected, one in HDMI port and other one in DisplayPort. After update and reboot, both displays do show an image, but it looks like plasma(?) is in a some kind of restart loop, the panel disappears and moves from one screen to another and I also hear the notification sound again and again.

However, if I disconnect the HDMI screen, then the one connected in DisplayPort does not wake up at all. Both screens do work with HDMI alone.

Screen in DisplayPort is Samsung Odyssey G5

Instead of this better post output of

inxi -Fza

As it will show different results when different monitors are connected, repeat for the relevant confiurations and post the difference.

Hi @fut, and welcome!

In order for us, or anyone for that matter, to be able to provide assistance, more information is necessary. To that end, please see:

Please also note and heed: Forum Rules - Manjaro

Hope you manage!

:bangbang: Tip: :bangbang:

To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:

```
pasted text
```

Or three (3) tilde signs, like this:

~~~
pasted text
~~~

This will just cause it to be rendered like this:

Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.

Instead of like this:

Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.

Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.

Thereby improving legibility and making it much easier for those trying to be of assistance.

:bangbang::bangbang: Additionally

If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:

LC_ALL=C bluetoothctl

This will just cause the terminal output to be in English, making it easier to understand and debug.

Please edit your post accordingly.

Actually it just suddenly started to work although I didn’t make any changes, strange. I think this topic can be closed, sorry and thank you for the help.
