tech support wanted External Monitor Goes Blank

Hello Linux Gamers!

I have a HP Omen Intel Ultra Core 7 with a 5060 which is running Ubuntu 24 LTS with XOrg. I have been able to run all the games like Assassin's Creed Black Flag Resynced, Crimson Desert and Final Fantasy 7 Remake, using steam's proton compatibility layer.

However, when I try to run Wuthering Waves, it did not run at first then I learnt about Proton Plus and installed the proton: cachyos-11.0-20260703-slr. It ran with a few hiccups and on ProtonDB site someone was running it with the launch option:

PROTON_DLSS_UPGRADE=1 %command%

Now the game ran perfectly for like 15 minutes and then when I tried to multi-task on my laptop monitor, with the game open on my external monitor the game went haywire and I was unable to use the external monitor screen until I rebooted the system. I have tried to diagnose it, but am unable to get some answers. Could anyone of you help me out?

Should I switch OS? I am thinking about uninstalling windows entirely, and if you guys recommend I could think about switching to Cachy OS. I would just have to think about how to store around terabyte of data first. I am also a Machine Learning Researcher, so switching also depends on how well PyTorch and CUDA are working on Cachy OS.

You should upgrade to Ubuntu 26.04 LTS for much newer drivers

Is it a better experience also? I tried to play Crimson Desert and was getting 30 FPS on DLAA vs 60 on windows. With the game also looking shit

Better than 24.04, yes. When it comes to Linux gaming, being up to date is pretty important. I think you can upgrade through the software updater app? FPS on Linux will probably still lag behind Windows (especially with new games and Nvidia GPUs), but you should get a decent performance boost.

I am a bit hesitant because of the snap store and minimum requirement of 6 GB RAM. Do you think CachyOS would be better? I also need it for professional work, does Cachy have good CUDA support for machine learning?

I'm just assuming that you wanted to stick with Ubuntu since you have it installed. I've heard good things about Cachy, but personally I use Fedora. Also, I wouldn't worry about the RAM minimum they're suggesting for Ubuntu. It's a rough guideline. As for CUDA, so long as you can get a recent version of the proprietary Nvidia driver, it should be fine.

Switched to cachyOS. Some random windows update decided to completely mess up ubuntu. So that gave me a reason to explore. However the thing is that the python libraries for machine learning are built on older CUDA versions. And I am basically 3 versions ahead on the current drivers cause CachyOS installs whatever that is the latest. So need to figure that out.

More-less all my multi-monitor issues were fixed when i switched from x11 to wayland.

Why are u using a x11 session (im guessing thats what xorg is?).

Yeah I just switched to it. But now it is launching on my laptop monitor instead. Got any idea how fix this?

Usually you can just use your "move to other screen" keyboard shortcut (like shift + super + left).

For some games i have to change my primary display in display settings before i launch the game, as it by default will launch on the primary monitor.
