I have recently installed the NVIDIA drivers on my Xubuntu 15.10 machine but I had to remove them due to improper multi-monitor setup. Everything went fine, except for the fact that
gpu-manager seems to overwrite my
xorg.conf file with a wrong version containing NVIDIA stuff.
I know that there is a reported bug related to this, and I tried applying the hotfix suggested there but to no avail; namely, I changed
#start on (starting lightdm # or starting gdm # or starting kdm # or starting xdm # or starting lxdm) task exec gpu-manager --log /var/log/gpu-manager.log
My xorg.config file keeps being overwritten with the NVIDIA stuff.
Any other suggestions? I am also a bit concerned that some people suggested that the hotfix above might freeze the syystem (whatever that means).
