Comment 36 for bug 1798961

It turns out that the installation without nvidia drivers and the secureboot option also causes errors. After some time using the laptop, the screen freezes and only holding down the power button allows you to turn off. Unfortunately, after switching on again, there was a problem with the grub welcome screen. I could not even enter the bios settings. There was only a black screen. I had to press the power button several times until I was able to do it after an hour.
I have been using ubuntu for several years and this has never happened to me. The problem appeared a week ago on January 23. Previously, everything was fine.
