sry for my english

Installed Ubuntu latest version (18), the first time I installed it without connecting to the network, noticeable lag graphics shell (especially noticeable when watching video, video card I have GTX 1050 Ti). Execute the command lspci -k | grep -EA2 'VGA|3D|Display'


01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1)    Subsystem: Gigabyte Technology Co., Ltd GP107 [GeForce GTX 1050 Ti]
    Kernel driver in use: nouveau

Decided to upgrade the drivers, as it is written here


after reboot system i get black screen, even the grub is not shown, the expectation that will pass by itself, too, did not work. Reinstalled system, only this time was connected to a network, after installation again get the black screen (probably, at once downloaded actual drivers ). How i can to fix ?

I'm not exactly an expert but in Ubuntu 16.04 when I had driver problems I was able to type: Cntrl-Alt and f1 or f2 (or similar... try the other 'f's on your keyboard) and get a terminal or command prompt. Then, at the prompt, the older version had a command "sudo systemctl start lightdm.service" that allowed the GUI/graphical interface to work. Perhaps systemctl and lightdm are still used in Ubuntu 18?

I hope that helps or leads to a solution. Good luck.

  • it didnt work for me(((
