I have been a 20+ year windows user and have installed various versions of Linux for few days, That changed with Windows 11 - I have been running ArcoLinux for 2 months. I have decided not to go back to windows. It has been interesting journey so far and have been reading up as much as I can. ArcoLinux YT channel has been great help along with this subreddit and manuals.
My setup: Intel 4th gen Laptop with FHD resolution (eDP1) and an external 5K display on DP1. I don't like using multiple displays. I'm essentially using laptop like a desktop replacement with the lid of the laptop closed. The default resolution that Display shows when i first setup the system was 2560x1080. Monitor supports 5120x2160 at 30Hz and I use that resolution. It survives restart/updates (lockscreen looks like 2560x1080) EXCEPT when the monitor is turned off and turned back on. It seems like for some reason it resets the resolution back to 2560x1080 and I have to go back to display and change resolution. I am using xfce DE.
I have seen couple of YT videos where there is instructions to create monitor.conf file so it sets it permanently and can survive a restart, which I am not sure my situation is. Below is my monitor.conf

I am surprised at the last line. When I took this report, the screen resolution is 5120x2160 @ 30.00 Hz. While the above displays the 2560x1080 - may be that's why its going back to that resolution when i turn off and on the monitor.
