Trouble with UMU on Deck

whenever i try running a game in Heroic with Proton-GE and UMU on my steam deck in desktop mode, there is no issue.

when I switch to gaming mode and try to run the exact same game, it stays on the steam loading screen forever, like it is trying to load, but it does play sound.

I've tried deleting every instance of umu-run that I can, but there is one in

/usr/bin

/usr/bin

that I can't delete, and i suspect that may be the problem child.

this does not happen in desktop mode or with umu off with proton.

any help would be appreciated, let me know what else to provide by way of detail or logs.

I've asked several times in the Heroic discord, and they don't seem to know what's up with this

RawToastOP•12/31/24, 7:21 AM

every game does this, here's the game log for Cat's Quest, though

why are you trying to delete umu-run from /usr/bin? are you trying to replace it with another version?

if so, check your $PATH, both /usr/local/bin and /usr/bin should be higher priority than /usr/bin, meaning if you drop in your own custom version of umu-run into either /usr/local/bin or ~/.local/bin it will be higher priority than the one your failing to remove. You will not be able to replace umu-run unless you create your own custom version of bazzite otherwise

I'm trying to make it reinstall

RawToastOP•12/31/24, 7:05 PM

it's not necessarily the answer, though

RawToastOP•12/31/24, 7:19 PM

it may not have anything to do with umu, are there repair tools built into Bazzite?

RRawToast it may not have anything to do with umu, are there repair tools built into Bazzi...

No, the root is read only and every single person has the exact same install of UMU bit for bit

Kyle Gospo•12/31/24, 8:59 PM

There is no way for you to reinstall and there would be no difference if you did

Kyle Gospo•12/31/24, 8:59 PM

The image itself is checked, if you didn't pass checksums during an update the update would fail

RawToastOP•12/31/24, 9:02 PM

makes sense

RawToastOP•12/31/24, 9:03 PM

so, any suggestions?

Kyle Gospo•12/31/24, 9:08 PM

I'm not sure here, it does seem to be a prefix problem based on your log

Kyle Gospo•12/31/24, 9:08 PM

I'm using this on nine different titles without issue, so I know it's not a generic UMU problem

RawToastOP•12/31/24, 9:08 PM

i've deleted the prefix a bunch

Kyle Gospo•12/31/24, 9:08 PM

Have you tried wiping out all of your prefixes entirely?

Kyle Gospo•12/31/24, 9:09 PM

How about getting the game to start with a non-UMU runner

Kyle Gospo•12/31/24, 9:09 PM

And then switching

RawToastOP•12/31/24, 9:09 PM

that also produces the same result

Kyle Gospo•12/31/24, 9:09 PM

What's your hardware?

Kyle Gospo•12/31/24, 9:09 PM

Never mind, steam deck

RawToastOP•12/31/24, 9:09 PM

it's the steam deck LCD

Kyle Gospo•12/31/24, 9:09 PM

Hmm ..

RawToastOP•12/31/24, 9:09 PM

no worries

Kyle Gospo•12/31/24, 9:10 PM

00e0:err:module:import_dll Library mfc140u.dll (which is needed by L"E:\Heroic\CatQuest\Cat Quest_Data\Plugins\x86_64\UnityNativeChromaSDK.dll") not found

Kyle Gospo•12/31/24, 9:10 PM

At the very least here you're missing mfc140

Kyle Gospo•12/31/24, 9:10 PM

Try installing it with wine tricks

RawToastOP•12/31/24, 9:10 PM

sure

RawToastOP•12/31/24, 9:11 PM

thanks for clarifying which one :D

RawToastOP•12/31/24, 9:17 PM

same result in game mode, and i can still launch it as is in desktop mode

RawToastOP•12/31/24, 9:17 PM

it's almost like game mode doesn't let it access something? i'm not sure

RawToastOP•12/31/24, 9:21 PM

this is a run of the game on desktop mode and it shows correctly, and exits correctly

RawToastOP•12/31/24, 9:27 PM

those launch commands are actually quite different

RawToastOP•12/31/24, 9:30 PM

maybe not that different, just ordered differently.

and the one that isn't working has an extra

--skip-version-check

bump

RawToastOP•1/2/25, 3:55 AM

i've posted the issue here:
https://github.com/Open-Wine-Components/umu-launcher/issues/318

RawToastOP•1/2/25, 5:24 AM

it may be a bazzite bug based on what that thread speculated

RawToastOP•1/2/25, 5:30 AM

the relevent piece

Assuming those logs are correct and I'm not missing anything else, the problem is because neither STEAM_COMPAT_TRANSCODED_MEDIA_PATH, STEAM_COMPAT_MEDIA_PATH, STEAM_FOSSILIZE_DUMP_PATH, and DXVK_STATE_CACHE_PATH are set for umu to get the app ID from. Those env vars being set are a requirement to fix game windows.

RawToastOP•1/2/25, 5:30 AM

is this a problem with something i've accidentally deleted?

RRawToast it *may* be a bazzite bug based on what that thread speculated https://github.c...

Kyle Gospo•1/2/25, 6:51 AM

if it was it'd be broken for everyone in an identical way

Kyle Gospo•1/2/25, 6:51 AM

since we all have the same image, bit for bit

RawToastOP•1/2/25, 7:08 AM

right, that's why i'm thinking i messed something up

RawToastOP•1/2/25, 7:08 AM

reiterating the question

RawToastOP•1/2/25, 7:13 AM

a better question, do you have any of these listed environment variables set?

Kyle Gospo•1/2/25, 7:39 AM

we don't change anything about those environment variables

Kyle Gospo•1/2/25, 7:39 AM

and if this was a problem it'd affect more than you

RawToastOP•1/2/25, 7:40 AM

right, we're on the same page with that. do you know of anything i could have done to mess this up?

Kyle Gospo•1/2/25, 7:40 AM

I do not

Kyle Gospo•1/2/25, 7:40 AM

testing will have a slightly newer umu if you want to try it
