I found an instruction to add OpenGL,
I wanted to try it, will the current driver will not break ?
I understand that OpenGL in this system is not configured?
I'm trying to  - glxgears.  I get 45 fps and the error is libGL error: unable to load driver:
OpenGL is included, just add 'LD_LIBRARY_PATH=/usr/lib/GLSHIM' before the command .
edit: most content already make use of OpenGL ES => Mali, what exactly are you trying to achieve?
for example, I watched the installation instructions for Minecraft,
you can try your luck, but most of absent content from RetrOrangePi have Raspberry-only dependencies
there's nothing much as far as I understand, GL driver, Java
yes, but you need to make the GL driver work on the armbian desktop, at the current setting glxgears reports that it does not see them
As said, OpenGL is included, but you have to add 'LD_LIBRARY_PATH=/usr/lib/GLSHIM' (environmental flag) before the command . That's what we do, for example, with the Amiga emulator.
I connected to my orange pi via the rdp protocol as root, after logging out of my account. now I get such results
root@RetrOrangePi:~# glxgears
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
740 frames in 5.0 seconds = 147.720 FPS
980 frames in 5.0 seconds = 195.131 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":11.0"
     after 4116 requests (37 known processed) with 0 events remaining.

Does this mean that the driver is loaded and running?
you NEED to add LD_LIBRARY_PATH=/usr/lib/GLSHIM before the command, like this:

LD_LIBRARY_PATH=/usr/lib/GLSHIM /usr/bin/glxgears

btw, it will only work on X desktop
