I have just installed Ubuntu as second system after Windows 10. For the first time Ubuntu stop responding after few minutes after logging in . Now everything is ok except I can't shut down and reboot it. When i click on reboot or shutdown mouse disappeared and nothing happened .I need hold my power button to turn off it. Ubuntu and windows is on ssd . Laptop just new and on Windows everything is ok

PS I cant open settings in Ubuntu it freezes

  • It works.It very fast to boot now. What this parameter do?(no mode set).But i see that in walpaper there are lines(only there!!) See photo b.radikal.ru/b35/1906/dd/16150939ddce.jpg – sasha_tv Jun 12 at 13:13
  • I forget reboot. So when update i didnt do anything? – sasha_tv Jun 12 at 13:17
  • I mean i must forget about this when upgrading system? PS why on that walpaper was lines and why linux 19.04 live freezes? – sasha_tv Jun 12 at 13:22
  • actually it depends. for some hardware under 19.04 that fix is not necessary, for some other hardware it is still necessary, you'll have to try and find out. – tatsu Jun 12 at 13:24

Your laptop has newer hardware but there is a solution for this.

Open a terminal, type:

sudo nano /etc/default/grub

then on this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

add nomodeset, like this :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Ctrl+X and then type Y and Enter, you'll be back in the terminal with the file saved, now you can type :

sudo update-grub

this will solve the issue.
