GLXinfo on retropie (pi5 - 64 bit)

[DTEAM]

Hi, is there a way to get glxinfo on Retropie.
The Pi OS lite version seems to unallowed the possibility to run glxinfo on a Pi5 64bit.

pi@retropie:~ $ sudo apt-get install mesa-utils
Installation done (I cut the log)

pi@retropie:~ $ glxinfo | grep "OpenGL version"
Error: unable to open display

pi@retropie:~ $ glxinfo
Error: unable to open display

If not, does somebody have the log for a Pi5. Thanks

glxinfo works only from a desktop session, it's an X11 utility. You either start an X11 desktop session or - if you're using a Wayland session - make sure XWayland is supported before running the utility. glxinfo does not work without a desktop session.

I can run glxgears with

startx glxgears

but it opens a fullscreen windows with the 3 gears and nothing is possible after that. it's not a popup window, but a fullscreen window. any idea to open it in popup mode to be able to continue to write commands like glxinfo

Maybe I don't have the good appraoch. For now it's a deadend for me.

@DTEAM That's not how you run X11 programs. Please install and then start a normal desktop session that will allow in turn to run the desired (X11 based) programs from it.
