Screen Tearing on AMD Drivers

[robertzo]

So, I have been using Endevouros with little problems, but after connecting to an external monitor, the screen started tearing really bad. I thought it was just the monitors problem, so I disconnected it and rebooted the computer. The tearing remains! Here is an inxi --full output:

I tried updating the system and rebooting and nothing worked.

Someone came up with a potential solution on this forum, already:

Maximum resolution for secondary monitor changes after system is locked for long periods of time

Hello, I’ve been having some troubles with my setup and I would appreciate it if anyone were able to help. The title basically describes the issue. When my screen is locked for long periods of time, the display settings go from this: [Screenshot_20230505_193833] To this: [Screenshot_20230424_003439] and I’m unable to turn the resolution up any higher than that until I either turn the monitor off and on, reboot the computer, or put the computer into sleep and wake it. I’ve posted a few logs …

Thank You, even though my solution isn’t the same as that, I found that KDE automatically switched my resolution to the 2nd screen’s resolution. I ended up switching back and it worked

That is great!

…and yes, this forum does have a search-function!
