Problem wit solvespace (Toshiba SATELLITE C670-1CK + Bebian 11 + XWayland + Intel Core Processor Integrated Graphics Controller (by Alain Térieur)
I have a problem with solvespace that can't create an OpenGL context, either with a 3.0 rc2 version provided by debian or the 3.1.0+git1922-50cbecb-1 version provided by notesalexp.

- For solvespace 3.0 rc2 (debian) a workaround is possible by running the following commands in a terminal:

$ export GDK_BACKEND=x11

$ solvespace

Note: if you try to run solvespace directly from gnome it doesn't work any better after that. You have to launch it from a terminal as mentionned above.

- For solvespace 3.1.0+git1922-50cbecb-1 this workaround does not work.

You will find 2 files attached to this post with additional information. Hoping that helps to fix the problem

Why are you using XWayland? Solvespace runs native Wayland for years, in spite of its classic look ;-)

Hi Paul,

Xwayland is automatically installed with Debian 11 (Bullseye). I have another Toshiba - also running Bullseye in the same OS configuration-, with a Nvidia GeForce 315, on which I can run the two versions of Solvespace I spoke about without any problem. Apart the processor, the only difference between the two computers is the video card.

Problem solved (by Alain Térieur)
Note : Intel Graphic chipset i915

1/ created - as root - a file named i915.conf in /etc/modprobe.d/
with the following content:

options i915 enable_guc=2

2/ created - as root - a file named in /etc/profile.d/
with the following content:

export GDK_BACKEND=x11

And then the two versions of Solvespace are running flawlessly
