Good afternoon everyone, the problems start right out of the box, the system 18.04.1 Ubuntu LTS, GNOME 3.28.2, there are noticeable brakes, jerks and freezes when rapidly moving Windows, browsing (google chrome, fifefox) scroll less heavy sites. Comp GeForce 9800 GT/PCIe/SSE2, 8 GB RAM, AMD® Athlon(tm) 64 x2 dual core processor 6000+ x 2, hdd 1TB), inhibits the same as on the wood of the box ie free and proprietary drivers for nvidia, digging into the settings of the browsers and drivers to no avail. May be someone faced with this? may need more fine tuning. The word no stocks of iron in a computer has never been observed.
