Issue description:

I'm in optimus laptop. Godot can run well on normal mode (with intelHD) but not in GPU mode. These are the error:

With primusrun

it just won't start

~/Applications >>> primusrun ./Godot_v3.1-rc2_x11.64                           
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":8"
      after 7 requests (7 known processed) with 0 events remaining.
XIO:  fatal IO error 2 (No such file or directory) on X server ":8"
      after 7 requests (7 known processed) with 0 events remaining.

With optirun

I can run until the project list but when I opened a project, Godot closes itself.

~/Applications >>> optirun ./Godot_v3.1-rc2_x11.64                        [130]

...

I can run glxgears just fine with both of them (primusrun and optirun) and can play pc game run through wine with primusrun.

Here is when it works using integrated GPU

Thanks. The crash when opening a project is because it spawns a new process and doesn't pass the command line arguments. You can work it around with optirun ./Godot_v3.1-rc2_x11.64 -e --path path/to/project to open it directly.

Setting DRI_PRIME=0 in the environment should also work it around.

Can you try running with these options?

./Godot_v3.1-rc2_x11.64 --verbose --video-driver GLES3
./Godot_v3.1-rc2_x11.64 --verbose --video-driver GLES2
