[BUG] - Linux Appimage and pacman package crash on startup. "GPU process isn't usable. Goodbye."

[Cknight70]

Describe the bug
When starting r2modmanPlus with both the appimage version and the pacman package, the program will start and show a blank r2modmanPlus window for a few seconds, then close.

To Reproduce
Steps to reproduce the behavior:

1. Install the pacman package, or simply run the appimage provided in releases or on the thunderstore page
2. Run program

Additional context
I have a Nvidia graphics card, I'm using the proprietary driver on Xorg, I am Running Arch linux.

I ran the app image in bash and got the following log

$   /ebkr-r2modman-3.1.49/r2modman-3.1.49.AppImage 
xdg-mime: application argument missing
Try 'xdg-mime --help' for more information.

Hi, I've seemed to have fixed the issue myself by appending --no-sandbox at the end of the run command for this.
so for example I can type r2modman --no-sandbox in bash, or add the argument to the desktop startup file like this screenshot

Same issue with the deb installation, just seems like it's every single package that is broken.

Your solution worked for me, thanks!

Are the people here experiencing this using NVIDIA cards? Honestly wondering if this is a recurring theme as it was in #1383

[Jaskowicz1]

@al12gamer yeah I'm on Nvidia getting the issue 😅 the no-sandbox flag does fix this though.

My friend experiencing the issue has NVIDIA as well. I haven't experienced this on the Intel test bench nor AMD gaming desktop so I'm wondering if there's something to that.

I'm getting this issue with my deb install. This did fix it

Same .deb install issue (with Nvidia graphics), @Cknight70 's suggestion to use the --no-sandbox option worked to get it started.

How do I add the --no-sandbox flag on Fedora on GNOME? I'd like it to run that flag any time I launch the RPM package

[Cknight70]

@candroid-man

Find your .desktop file in

/usr/share/applications/ or /usr/local/share/applications/ for applications installed system-wide, or ~/.local/share/applications/

Find the "exec" line, and add the --no-sandbox parameter on the same line. So it may look like Exec=r2modman --no-sandbox
