χαμηλό screen refresh rate

Σόρρυ για το μεγάλο email. Μπορεί κάποιος να μου εξηγήσει γιατί στο 
screen resolution του gnome βλέπω ότι το refresh rate είναι 50Hz (και οι 
τιμές που παίρνει είναι 51,52 μόνο) ;

Τα settings του μόνιτορ τα κάνω τόσα χρόνια copy paste και πάντα έχω 
refresh rate 85Hz.

Δεν ξέρω αλλά τώρα τελευταία το ubuntu μου τη σπάει λίγο. Σε ενημερώσεις 
αντιγράφει αρχεία χωρίς να ρωτήσει και χάνω settings. Το τελευταίο που 
θυμάμαι είναι με το xorg.conf το οποίο μου έβγαλε settings από το 
πληκτρολόγιο, όπως και αυτό τώρα με το refresh rate (που προηγουμένως 
δούλευε στα 85Hz)


Παραθέτω το xorg.conf
