I didn't have any problem with my Graphics driver or OpenGL before, and I was able to play 3D games using POL. But when i was just looking around in my system I came up with nvidia-settings so when I started it up it gave me a message saying
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run
nvidia-xconfigas root), and restart the X server.
So I searched the Wiki about this problem and then I found this Wiki page.
I went along with the tutorial, I noticed that I already had the correct driver installed. However, hoping to get Nvidia graphics to work on Xserver, I generated a Xorg configuration file at /etc/X11/mhwd.d/nvidia.conf
And then I ran sudo mhwd-gpu --setgl nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf to select that configuration.
I noticed that I already had a .conf file named intel.conf there. However, The Xserver failed to restart when I pressed ctrl + alt + backspace.
I reset the Xorg using sudo mhwd-gpu --setgl nvidia --setxorg /etc/X11/mhwd.d/intel.conf
Which gave me my GUI back but now I can't run any game. Whn I am starting PlayOnLinux it says that
PlayOnLinux is unable to find 32bits OpenGL libraries. You might encounter problem with your games
and
PlayOnLinux is unable to find 64bits OpenGL libraries. You might encounter problem with your games
I will upload any log files needed. Thanks in advance, Bhashithe
