Bumblebee (optirun, primusrun) doesn't work with Flatpak #869
Description
I've been testing the new Steam Flatpak with my Optimus setup, and I ran into a some issues. Most importantly, couldn't get it to play well with Bumblebee (either optirun or primusrun). Obviously, the sandboxed Steam doesn't have access to the primusrun or optirun executables, so I couldn't use the official trick of changing the games' launch settings to use primusrun %command%. So I tried the other trick that normally works; running Steam itself using optirun or primusrun, and expecting games that it launches to "inherit" the use of the discrete card. For that, I used optirun -b primus flatpak run com.valvesoftware.Steam. However, to my disappointment, it didn't work at all. In fact, Steam itself didn't seem to use the discrete GPU either, not just games. I confirmed this using the org.freedesktop.GlxInfo Flatpak.
I've ran quite a few commands in sequence and logged their output, in hopes it would help identify the issue. Let me know if you need me to test anything or run any other commands.
