PrusaSlicer not running with flatpak when running on dedicated gpu

[PredellaN]

Description of the bug

When starting prusaslicer with "flatpak run com.prusa3d.PrusaSlicer", the application starts and works normally.
When starting with:

• "flatpak --env=__NV_PRIME_RENDER_OFFLOAD=1 --env=__GLX_VENDOR_LIBRARY_NAME=nvidia run com.prusa3d.PrusaSlicer"
• "switcherooctl -g 1 com.prusa3d.PrusaSlicer"
  The application stops here:

nicolas@pop-os:~$ flatpak run --env=__NV_PRIME_RENDER_OFFLOAD=1 --env=__GLX_VENDOR_LIBRARY_NAME=nvidia com.prusa3d.PrusaSlicer

Message: 21:35:42: Starting PrusaSlicer flatpak with entrypoint script
--------------------------------------------------------------------------
nicolas@pop-os:~$

Starting the 2.8.0 AppImage version with switcherooctl -g 1 or with the environment variables specified before, the application starts on the dedicated GPU as intended. Other flatpak applications i am using run on the dedicated GPU without issue.
Enabling device=dri won't fix the issue.

Project file & How to reproduce

• install the flatpak version of prusaslicer on a device with hybrid graphics
• run prusaslicer with either of the above mentioned commands

Hello, @PredellaN , Could you check if PrusaSlicer has permission to use the GPU? You can add the necessary permissions using this command: flatpak override --gpu=all com.prusa3d.PrusaSlicer. Personally I would recommend flatseal to set/manage flatpak permissions in general.

Hello @Jan-Soustruznik ,

nicolas@pop-os:~$ flatpak override --gpu=all com.prusa3d.PrusaSlicer
error: Unknown option --gpu=all

I assume you meant --device=all , however it doesn't solve the issue (it is already on by default). --device=dri also doesn't solve the issue

Same issue here with current Ubuntu 24.04 with slicer 2.9.0. I was previously using the AppImage without problems, but the flatpack refuses to start on the secondary gpu.

Same issue Ubuntu 22.04. Appimage was working previously. Before I had the nvidia drivers installed on flatpak, prusa slicer would open but the 3d window wouldnt render. Instaled the Nvidia drivers and now it won't even run.

Used flatseal to give permission to the GPU acceleration and wayland

workaround: there is an appimage build at https://github.com/Samueru-sama/PrusaSlicer/releases/tag/continuous , functions correctly with discrete gpu

Hey doesn't probonos fork work? it is more recent.

See relevant issue: #13653

My build is old and from this old PR probonopd#5

Hello this is most probably a duplicate of #13618.
