libGL.so.1 => /usr/local/lib/x86_64-linux-gnu/libGL.so.1

you’re running some non-standard OpenGL in /usr/local
Please uninstall.

ok, to uninstall i need to remove it? i renamed it to libGL.so.1.bak.
Now when running ldd /usr/bin/glxinfo again:

libGL.so.1 => /lib/x86_64-linux-gnu/libGL.so.1
also opengl renderer remains llvmpipe.

So i renamed also that libGL.so.1, but after ldd /usr/bin/glxinfo will just say to me that there is no libGL.so.1 and startx won’t work.

reinstalling apt nvidia 515 drivers will get me back to the start

There’s also libOpenGL.so etc. in /usr/local you need to remove. likely some self-compiled mesa, you should know what you installed and where to run make uninstall.

ty for the replies so far, i have no info on what has been installed though, through synaptic i gathered these packages:

2022-08-23-214308_1119x382_scrot
2022-08-23-214308_1119x382_scrot1119×382 69 KB

uninstalling some of these with apt will pretty much remove everything on my system , so i’m clearly doing something wrong or simply i’m not understanding the situatuion

is there a way to edit some configuration to successfully point to nvidia opengl rather than uninstalling?
Let’s say that i find the right package to uninstall though, what should i do after uninstalling? just reboot? reinstall nvidia drivers? run some specific commands?

So it’s not your system?
/usr/local is usually the default location where self-compiled stuff gets installed, i.e. download mesa sources, run configure, make, make install.
No packages get installed there, the location is usually empty but is searched first when libraries are loaded, to override system libs. Configured in /etc/ld.so.conf
Please check what’s in those directories
/usr/local/bin
/usr/local/sbin
/usr/local/lib
/usr/local/lib/x86_64-linux-gnu
and empty them in case you don’t find things you know and want to keep.

that worked thanks! i checked those directories and removed the unnecessary
