I've installed Ubuntu 17.10 alongside with Win10 on my laptop, but it works very slowly although my laptop has Core i5 7-th Gen, 16gb ram, gtx1060-6gb. The animations are very slow, page scrolling isn't smooth and all windows render slowly from top of the window to bottom. I think the problem is in gnome-shell or my graphics card drivers, because after I killed the gnome-shell process, mozilla worked perfectly.
I've tried to install proprietary drivers (and nvidia prime after that) for my nvidia card, but after installing I can't even boot in Ubuntu - I get
Stopping User Manager for UID 121.... So I deleted them in recovery mode.
Why the system works so badly? What should I do?
