Game Version


What version do you use?
Steam

What expansions do you have installed?
(DID NOT ANSWER QUESTION)

Do you have mods enabled?
No

Please explain your issue is in as much detail as possible.
In a linux laptop with an intel integrated GPU + nvidia GPU running hybrid mode, when you launch stellaris on the dGPU you get a black screen. This is a know bug of chromium or nvidia. You can work around this by editing the launcher and adding --disable-gpu. This probably affects other games that use paradox's launcher.

Steps to reproduce the issue.
1-Setup nvidia hybrid mode. 2-Launch stellaris with "__NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia "$@"" 3-Get a black screen

This is an easy fix.
Replace this line on the "Paradox Launcher" linux script:

"${SCRIPTPATH}"/Launcher --no-sandbox "$@"

with this:

"${SCRIPTPATH}"/Launcher --no-sandbox --disable-gpu "$@"

This has the side effect of disabling gpu acceleration on the launcher, but nobody will notice.
