I was a Windows user for a long time. But i found Ubuntu 20.04 more good. So, i switched to it ( Dual Boot) . The only problem with Ubuntu is boot problems. I frequently end up stuck on the boot screen.
I updated my kernel and ubuntu stopped working. It get stuck on reboot.
Sometimes, i type in terminal sudo reboot to reboot my pc.
The logo of ubuntu comes. After few seconds black screen come and then again ubuntu screen come. Then a forever black screen come.
After, this i changed some Grub file settings ( of splash screen) it worked. But then my Nvidia X server settings became empty. Then i switched to newer Nvidia driver. Then black screen came.
I don’t know, i fix a bug to get another bug in Ubuntu. Sometimes, i just reinstall ubuntu.
