I have a dual monitor setup, and with every kernel since 6.12 LTS, then the dual setup gets forgotten, and my 2nd monitor stops working after leaving unattended for a short time. I have disabled the screen saver and sleep timers, but still the problem occurs. Even the latest LTS (6.18) suffers from this problem. If I disconnect the 2nd monitor, and reconnect, or reboot then the 2nd monitor works fine.
If I use Display with any kernel after 6.12, then the settings are not remembered, and usually fail to take, however if I “revert” them, my previously working dual setup is enabled, until the next screen lock.
I’m running the latest stable version of Manjaro with the Cinnamon desktop, although I have tried KDE, and the problem also seems to occur with that desktop also.
I’ve tried EVERY kernel version (available in Manjaro settings) after 6.12, and they all exhibit this problem.
Suggestions?
Hi @gandaflmeister, 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:
-
[HowTo] Provide System Information.
At bare minimum we would need you to please provide a detailed description of the problem faced, as well as the output to:
inxi --filter --verbosity=8 --color=0
- [HowTo] Post screenshots and links,
- [HowTo] Request support, and
- [HowTo] Post command output and file content as preformatted text.
Please also note and heed: Forum Rules - Manjaro
Those with privacy concerns: note that when -z, or --filter is used, all personally identifiable information is filtered out from the resulting inxi output. 
Hope you manage!
Tip for legibility:
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.
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.
Note that the above text is partially pre-prepared as a general introduction for new forum users. Please take the time to follow links given and learn how to create effective support requests and encourage quality responses.
