Actually I wanted to correct the well known Ubuntu brightness issue as addressed in this YouTubeVideo
In essence, the guy says to change the Nvidia driver from open source to any other proprietary one.
But I did a mistake of cancelling the change before it could successfully do it, thus not properly assigning the new one and not even going back to the old one.
It looked somewhat like this:
And now I am stuck in the console mode. I have tried installing Nvidia-304 from there, but no luck.
I believe I need to reset some internal settings, but have no idea How To?.
Relevant log and configuration files:
50-synaptics.conf
only as it says in the log, that error in line 10 of50-synaptics.conf
. Moreover the file before it does not even have a line 10.
