Yeah this is the reason most probably. After the UI update I had the exact same problem. After 2 days of search for solution I finally found it. When it tries to open with discrete GPU it just blinks and doesn't open. I can only open it with integrated GPU. And you definitely have to use DRI_PRIME=1 argument for every game to open them with dGPU. It is kinda annoying but it's only solution for now until Valve updates it.
I can only think of Waydroid if you are using Linux.
Debian not recommends testing for everyday using. You definetely have to look at the site. Afaik it is basically a bad version of unstable that gets slow updates and it is only for testing purposes.
I think your problem is you are using a niche Arch derivative that has a small user base. You should definitely consider using more mainstream distros so you can easily find the help you need until you are comfortable and feel confident with using Linux.
Yeah I've been subscribed to both of them too but like I said I felt lazy to write all of them. Also Honest Guide's content range is broader and video styles are different. But Brick Technology is also good.
NJB is really pro Netherlands but I am kinda okay with that because I really didn't consume any media before that are pro Netherlands so it has a place to join with the pro America, UK and France media I guess.
I don't know these were posted or not but here is my suggestions which every youtube watching person probably already heard about most of them:
Not Just Bikes: Channel about Urban Planing-Living and how destructive the cars are.
History Matters: Short animated videos about historical events, narrated with humor.
my mechanics: Best and most detailed restorations ever.
NileRed - NileBlue: All about experimenting with chemical reactions.
Oversimplified: Like the name, oversimplified narrations of historical events but in a long form with animated depictions and humor of course.
Stefan Milo: Really informative research videos of archeology.
The Linux Experiment: Like the name suggests it's all about Linux.
Bad Lip Reading: It's in the name.
ChrisFix: Best car repair channel out there.
DIY Perks: DIY videos but heavy on the entertainment side rather than the doable diys.
Ethan Chlebowski: Trying to understand cooking from the perspective of homecooks.
Alex (the French Guy Cooking): Reverse engineering the recipes.
Brick Experiment Channel: Building Lego machines.
These all are high quality channels imo. There are a lot more but I am kinda lazy for now.
I don't understand recommending an another company distro to user who is happy with using Fedora but want to change it just because it is a company distro. (They both are actually community projects but let's ignore it for the purpose of this discussion)
After trying to do it with docker or ansible manually for hours and failing, this was soo helpful. So thank you.
