Re: [Nouveau] libGL error messages
By the way, why does it try to access /etc/ld.so.nohwcap 49 times when
failing once should be enough? One getpid() would seem enough too.
$ strace glxinfo -B 2>&1|sort|uniq -c|sort -n|tail -n 3
54 access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or
directory)
62 recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource
temporarily unavailable)
116 getpid()= 1422
I'll send you the full strace.

This will probably require a bunch of back-and-forth to debug. You can use gdb to work out why the load is failing. If it's in dri_fill_in_modes, then something went wrong in your downgrade. Feel free to join #nouveau on irc.freenode.net to discuss. -ilia ___ Nouveau mailing list Nouveau@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/nouveau

That's a NV4C or NV4E (i.e. nv4x).

OK, well 18.1.0 is completely busted for those GPU's. Either upgrade
or downgrade. But don't use that release. This is the fix:

Re: [Nouveau] libGL error messages
Are you on mesa 18.1.0 and using a nv3x/nv4x gpu? If so, update to 18.1.1. If not, provide more information. The error is that nouveau_dri.so can't be loaded, which means you're not getting acceleration. You can also make the error go away by sticking LIBGL_ALWAYS_SOFTWARE=1 into your environment or removing nouveau_dri.so.
