nvidia-prime fails to switch profiles (alternatives related)

[Jörn Schönyan]

Hello everyone,

nvidia-prime has more bugs with every release! On a fresh install of Kubuntu 14.10, I've installed nvidia-prime and nvidia-331. After the obligatory restart, the Nvidia chip was active. Trying to switch to the Intel profile looks like this:

joern@Aspire-V3-571G:~$ sudo prime-select intel
Info: the current alternatives in use are: ['nvidia-331', 'nvidia-331']
Info: selecting nvidia-331-prime for the intel profile
update-alternatives: /usr/lib/nvidia-331-prime/ld.so.conf wird verwendet, um /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf (x86_64-linux-gnu_gl_conf) im manueller Modus bereitzustellen
update-alternatives: /usr/lib/nvidia-331-prime/alt_ld.so.conf wird verwendet, um /etc/ld.so.conf.d/i386-linux-gnu_GL.conf (i386-linux-gnu_gl_conf) im manueller Modus bereitzustellen

That is only fixable by reinstalling Mesa, everytime I want to switch. Really annoying.

Status changed to 'Confirmed' because the bug affects multiple users.

The same for me on Ubuntu 16.04.
I just see no alternatives for mesa: Info: the current alternatives in use are: ['nvidia-367', 'nvidia-367']
Reintalling mesa didn't help for me.

The same thing happens to me. I'm on Ubuntu 17.10.

Info: the current GL alternatives in use are: ['nvidia-384-prime', 'nvidia-384-prime']
