I installed xcalib to adjust my screen contrast, and I executed this :

xcalib -co 0 -a

Which set my screen contrast to 0 , and now my screen turned dark, and I don't have any clue as to how can I reset this setting ?

Thank you

As first enter a TTY, this you achieve by pressing ctrl+alt+f1. There you can login whit providing your username and password. Then set the contrast back with the same command you have used to set it to zero.

xcalib -co 50 -a

Now you can logout of your TTY session by entering exit. Afterwards you can come back to your GUI by pressing ctrl+alt+f7.
