Mam problem taki jak w temacie. Konkretniej to przy instalacji sterownika wyskakuje mi błąd aby wyłączyć właśnie X Server, czy ktoś wie jak to zrobić?
Jeśli korzystasz z Ubuntu:
sudo /etc/init.d/lightdm stop
lub
sudo service lightdm stop
W innym przypadku podajesz nazwę menedżera logowania zamiast lightdm np. gdm/kdm.
sudo /etc/init.d/*dm stop
lub w przypadku slim:
sudo /etc/init.d/slim stop
lub gdy jest uruchomiony przez startx
killall -9 xinitDzięki, działa. Niestety system nadal nie wykrywa modelu karty graficznej, gdy wchodzę w ustawienia systemu i szczegóły 
To nie ma znaczenia. Sposób odczytywania tej informacji przez GNOME 3 dość dziwny i przy sterownikach własnościowych (przynajmniej nVidii) nie działa.
Pokaż wynik:
lspci -k
W ten sposób dowiem się z jakiego sterownika korzysta karta graficzna.

.
Czyli stery własnościowe zainstalowały się.
