I’ve given up on bluetooth and linux, I had trouble getting the high quality codecs to work consistently on either COSMIC or Gnome PopOS. Keeps defaulting to the low quality codecs.

Now I just use my DAC and wired headphones with a 3 meter cord

Try installing blueman or another bluetooth utility

Run blueman and select a different, high quality codec after you connect (you’ll probably have to do this every time you connect)

It sucks cause I really like the Mario Kart and Metroid Prime series and was hoping for more 3D metroid games, but there’s just so many other good games out there. Especially with Steam and the Steam Deck. I’ve had every nintendo console and handheld from the NES through the switch, but that’ll be my last console now that the steam deck exists and nintendo has become so hostile.

However I do wish there were more devices like the wii sensor and wiimote/nunchuk. I’d rather PC gaming go in that direction than with VR gaming cause I really hate having to move my neck around with VR.

Since the website doesn’t include a how-to guide, this blog post helps.

Yes. In Steam I tried both a native Linux game (Team Fortress 2) and a windows game (Expeditions Mudrunner) in compatibility mode with Proton. Both worked just fine but there are minor annoyances with COSMIC DE.

• COSMIC Settings: There’s no option to set your primary and secondary display, so I had to switch around some display port and HDMI cables.

• Display Issues: When I updated the display setting to 120Hz for my gaming monitor, it crashed the system and refused to boot the OS on restart, it would hang up with some error messages after the login screen. I had to start my desktop with a different monitor plugged in, and then connect my gaming monitor and make sure it was only set to 60hz so it wouldn’t crash again.

• COSMIC Files: The file system doesn’t display filesize of folders or groups of files, only individual files

Verdict: COSMIC is still in Alpha but it feels really crisp and snappy, smooth interacting with applications. You may run into some minor annoyances or bugs that could lead you to need to reinstall. If you’re like me who only uses Steam and Firefox and hardly any local files/applications, you’ll probably be fine if you run into any bugs. Also I have my laptop with Gnome POPos to fall back to if my desktop running COSMIC gets bricked and needs a fresh install.

For now I am having a better experience in COSMIC PopOS than with GNOME PopOS. For a few weeks now I wasn’t able to get the PopStore running in Gnome DE, and also my firefox kept freezing the entire system after leaving a twitch stream running for a few hours. None of the issues I was having with GNOME PopOS are here in COSMIC PopOS. I’m looking forward to all the improvements and updates until full COSMIC launch. Also planning to get a System76 gaming desktop with AMD, probably next year when I can save up some money and maybe COSMIC will be more refined by then.

Thanks, that helped. I installed Cosmic on my gaming desktop yesterday, runs everything I need just fine (after a bunch of updates and restarts) - Steam, Firefox, Freetube, VLC, Chromium, Discord

Some minor hiccups when transferring files from a flash drive or opening local files, but otherwise everything runs great on Firefox/Steam/VLC (95% of my computer usage)

I couldn’t get video conferencing to work (zoom/google meet) so I reinstalled PopOS. Also the timezone was stuck to UTC.

I don’t have an extra computer lying around just to test COSMIC, but I did like what functionality was there. Will definitely move desktop and laptop over once its ready for daily driver.

Edit: I forgot to connect to wifi before running the terminal commands to update and upgrade. I now have COSMIC working on my gaming desktop.
