Critique should be constructive
We within the Pop!_OS community welcome helpful criticism or ideas on ways to improve. However, basic "It's bad" or other simple negative comments don't help anyone fix anything.

This rule applies to both Pop!_OS and its projects as well as other products available from third-parties.
Don't post malicious "advice"
It can be funny to joke about malicious commands, however this is not the venue for it. Do not advise users to run commands which will lock up their systems, steal their data, or erase their drive. Examples of this include (but are not limited to) fork bombs, rm, etc.
Posts violating this rule will be removed, even if the post is clearly in jest. Repeated offences may lead to a ban. You may understand that the command isn't serious, but a new user might not.
No personal attacks
Posts making a personal attack on any user will not be tolerated.
No hate speech
Hate speech of any kind will not be tolerated. Any violations will be removed, and are grounds for a ban.

If I just start steam from the terminal, then it uses the iGPU and I still need to use the DRI_PRIME=1 environment varitable. This makes sense, because the DRI_PRIME=1 modifier is not set in the environment.
The workaround mentioned in that post (ie. changing
PrefersNonDefaultGPU=truetoPrefersNonDefaultGPU=false) is just a way to change the shortcut (.desktop) in GNOME from using the dGPU to iGPU by default (whereas right clicking on the shortcut and selecting "Launch with Integrated GPU" only temporarily overrides the setting for that single instance).It would be nice if was automatically detected on my computer... or rather it would be even better if we didn't have to workaround it at all and Steam just worked :]
I am stumped. How can steam/the system exhibit different behaviour when we are executing similar commands. Maybe it is because I have an amd+amd laptop so it automatically dumps the graphically intensive application to the dGPU. Or maybe because in a desktop, the dGPU is connected directly to the display, it not switching to the dGPU automatically as the user had specified the use of the iGPU. In my laptop(which has no mux switch), the iGPU will draw the frame on the screen even if it the dGPU which determines what is to be drawn
I'm not sure either, but this is on a laptop with an Intel CPU and AMD dGPU (strange mix) and more recently a NVIDIA eGPU.
The issues only appear with the AMD dGPU.
