I downloaded NomadBSD and managed to run it on my PC with a Radeon RX 570, also thanks to the special instructions for ATI/AMD in the handbooklet.
One thing that still does not work, however, is OpenGL support. I downloaded mesa-demos, and glxgears quits immediately, saying that i can’t find a double-buffered visual.
Xorg logs say that the file libglx.so is missing, and, indeed, the file it tries to load is a broken symbolic link.
How to make OpenGL work with such a graphics card? Is there a version of libglx.so for it?
you found a bug as it seems. Get the fixed
initgfx rc-script as follows:
# cd /etc/rc.d/ # fetch https://raw.githubusercontent.com/nomadbsd/NomadBSD/master/config/etc/rc.d/initgfx
rm -f /var/initgfx_config.id to force re-detection of the graphics card, and reboot.
