 K900 | #Jovian Experiments — NixOS on your Steam Deck, and other x86 gaming devices | 17:01:57 |
| K900 | But also gamescope on raw Nvidia is not exactly well supported | 17:02:05 |
 gshpychka | K900: sure, but to what extent? I'm not ready to give up just yet | 17:19:29 |
| K900 | To an extent where upstream doesn't care and I don't have hardware to test | 17:21:58 |
| gshpychka | that doesn't tell me much about what it means in practice in terms of effort required to make it work and whether its a hopeless endeavor or worth pursuing | 17:24:33 |
| K900 | I don't know | 17:25:05 |
| gshpychka | cool. hoping someone else will | 17:25:51 |
| gshpychka | niklaskorz: this gives me hope. care to share your setup? GPU/drivers/display | 17:26:53 |
 niklaskorz | RTX 4090 on driver 580.105.08 connected to a 3840x2160@120Hz TV over HDMI 2.1 | 17:28:43 |
| niklaskorz | variable refresh rate and HDR enabled, pretty much no issues | 17:28:55 |
| gshpychka | haha that's exactly my setup. | 17:29:12 |
| gshpychka | open kernel modules? did you specify any gamescope args? any env vars for proton/gamescope? change anything in gamescope/steam settings (developer mode?)? etc. it just doesn't work for me for some reason | 17:30:11 |
| niklaskorz | the only pain is that setting -steamos3(which is needed to get e.g. the bluetooth menu) limits the resolution to 1080p by default and you have to bump it to 4k resolution in each game's settings | 17:30:36 |
| niklaskorz | though if you don't need the bluetooth menu I'd suggest just not setting steamos3 | 17:30:47 |
| niklaskorz | I'll paste it into a gist, one sec | 17:31:42 |
| niklaskorz | https://gist.github.com/niklaskorz/a3d650a3954c7057c731fad820b69dbe | 17:34:22 |
| gshpychka | where is that set? haven't seen that in my reading | 17:34:26 |
| niklaskorz | it's included in the gist | 17:34:37 |
| niklaskorz | note that for some reason gamescope crashes when I launch it from cosmic-greeter, but it works fine when I use Regreet | 17:35:02 |
| gshpychka | I have the bluetooth menu and didn't set any custom flags/options. unless jovian-nixos adds that by default | 17:35:17 |
| K900 | We do | 17:35:25 |
| niklaskorz | I didn't use Jovian because I wanted to see for myself what the minimally working config for my needs would be | 17:36:07 |
| K900 | Oh god | 17:36:36 |
| gshpychka | oh - you're not using jovian, are you? | 17:36:39 |
| K900 | Please don't use nixpkgs gamescopeSessoin | 17:36:41 |
| K900 | * Please don't use nixpkgs gamescopeSession | 17:36:43 |
| gshpychka | got it, thanks | 17:36:45 |
| K900 | It's horrendously wrong | 17:36:46 |
| gshpychka | in what way? | 17:37:07 |
| K900 | Most of them | 17:37:40 |
