[BUG] - Not working on Ubuntu 22.04 - GPU process isn't usable

[pkkid]

App is not working on Ubuntu 22.04. We get the error message displayed below. I get the same error trying the AppImage or the deb install. After searching around to see what this means, it sounds like the app needs to be rebuilt with an updated version of Electron.

Trace/breakpoint trap

UPDATE: In Discord it was mentioned that using the --no-sandbox option on the AppImage gets the app up and running if you are OK running it that way.

I have exactly the same error message on fedora 35. The --no-sandbox flag also works with the .rpm version.

Same on Gentoo and running with --no-sandbox also works around the issue.

where to use --no-sandbox??

where to use --no-sandbox??

In the terminal after the filepath/filename.

Same issue on arch 5.19.13 and plasma 5.25.5, installed through AUR. Fixed by running r2modman --no-sandbox. To make the app work without terminal, find the .desktop file (usually in /usr/share/applications, usually named r2modman.desktop) and change Exec=env DESKTOPINTEGRATION=false /usr/bin/r2modman to Exec=env DESKTOPINTEGRATION=false /usr/bin/r2modman --no-sandbox.

I use r2modman --in-process-gpu rather than --no-sandbox.

how do i use the terminal to launch r2modman? when i try it says command not found

[al12gamer]

is it working fine in wayland for amd users? My friend saw this in wayland in KDE with an NVIDIA card

@IsaiahBjornlie If you're using the AppImage of r2modman, it will likely not be in your path.

You'll either want to open the directory of the AppImage in your terminal and then run it like ./r2modman.AppImage (e.g. by using cd path/to/the/folder).
Or if you're using KDE Plasma, you can also add it to the application launcher, where you can set the argument once and then just start it with one click whenever you want.

I'm not familiar with other desktop envs, but there should be lots of resources on the internet about that kind of stuff.

@al12gamer It's working fine in wayland with KDE and NVIDIA Card for me, using --in-process-gpu. If it doesn't work with AMD, then I guess there's a different issue between r2modman and the AMD driver.
Not a pro tho, just guessing.

@DreamyK9 it's worked fine for me on AMD
