Black screen after boot after changing adding something to conf folder.

I added a xorg.conf.d file called "50-gamma.conf" which contains:

display-setup-script=xrandr --output eDP1 -- gamma 1:0.93:1

Then I restarted my computer and it boots to a black screen. What happened?

I followed the instruction of the second answer from:

  • delete the .conf which you have created, it will solve – Ravan Jan 1 '16 at 1:33
  • are you able to delete the .conf file? – Ravan Jan 1 '16 at 2:39
  • Nope, I had to reinstall. I don't have access to terminal at black screen. – Dobob Jan 1 '16 at 2:54

    I have already reinstalled, so I don't have to do it anymore. But thanks though, I can use this in the future. – Dobob Jan 1 '16 at 7:39

I am going to provide you a solution to get back from black screen. The black screen is caused by the .conf file that you have created. First remove it, it will solve the issue.

Note : I have tested this solution

Step-1: Restart system. Go to advanced options --> select recovery mode.

step-2: Now using the arrow keys scroll down to root and then hit enter

Step-3: Run the following commands to remove:

mount -rw -o remount /
rm -rf /usr/share/X11/xorg.conf.d/50-gamma.conf 
reboot

Explanation: The first command changes permission, second remove file you have created.

As a side note: If I follow instruction from blog/web, is that always safe?
