Been driving KDE Manjaro for 5 months now no issues. Really none. The other day I updated to 6.15 kernal everything was great. Worked fine for a couple days. Yesterday I decided to try and install Gnome. So I downloaded the latest ISO. Was not good for me. This morning I downloaded the latest KDE ISO again and installed it. Got everything to where I was before I left. Went to jump into a game. No matter what Steam will not launch the game. Button turns green and instantantly closes. Sometimes if its a new game I will get the Vulcan shader windows for a bit then it closes and the game never launches. I have tried like 4 different versions of Proton. I don’t know what to do.
Please copy and paste text whenever possible. Once you pasted the text, please select it and press the </> button to properly format it.
Pictures take up more space, and can’t be searched, copied or quoted.
Also inxi -zv8 shows a lot more information than KDE’s system information, which could help those trying to help you.
Without more info, my guess is steam might be using the integrated GPU instead of the discrete GPU.
When you start steam in the terminal again, there might be a section of the output that looks similar to this:
Running query: 1 - GpuTopology
Response: gpu_topology {

driver_version_minor: 144

}
default_gpu_id: 1
Since both iGPU and dGPU are AMD, someone else will have to help you if steam is using the iGPU.
Here is the whole steam start up. I see both GPUs.

steam boots just fine there is no wait time almost. I only wait when I launch a game and its only for like 5 sec then the green play button returns and the game never loads.
6.15 is Release Candidate. There’s no reason why anyone should be using it as a daily driver unless they plan on reporting bugs upstream.
Can you reproduce the issue with 6.14 stable or 6.12 LTS?
