No godot 4 pre-alpha opens the editor, even the last one.

Godot 4.0-dev. 20211210 32bits

Ubuntu 20.04, intel CELERON 847

To open or create a project the editor loading screen freezes and creates a king of artifact that freezes on the screen, after killing the process, the program cannot reopen, i must delate the file "editor_settings-4.tres" to be able to start the program again.

The Intel Celeron 847 is based on Sandy Bridge, whose integrated graphics are too old to run Vulkan or OpenGL 3.3. You will have to stick to Godot 3.x which offers a GLES2 renderer.

How weird, because I can use 3.x with OpenGL 3.3. If so sad, I hope 4.1 will re-implement OpenGL 3.3 :(

Godot 4.0 will feature a GLES3 renderer for 2D: #53150
Advanced 2D functionality and 3D functionality in OpenGL will likely have to wait for a future 4.x release though.

You can already try out OpenGL by starting the editor with --rendering-driver opengl3 --single-window, but note that this command-line argument won't be automatically passed from the project manager to the editor. Therefore, you can create a project from the command line:

# Create a new project.
mkdir -p $HOME/Documents/Godot/my_project
touch $HOME/Documents/Godot/my_project/project.godot

# Open the editor.
/path/to/godot.binary --rendering-driver opengl3 --single-window ~/Documents/Godot/my_project/project.godot
