Please Note: Always make sure you have a full system backup before modifying any system files! Posted by Stephen Wagner at 8:08 AMДЁ0 Responses to вЂњUbuntu Linux вЂ“ Black screen and frozen system after upgrade and/or installвЂќ Restart your system, it should now boot!.At the bash prompt, execute the following command to regenerate the nf file on the /boot partition from your new default file: update-grub.Save the file and exit the text editor (CTRL+X to quit, the press вЂњyвЂќ and enter to save).HereвЂ™s an example of my line after editing (yours will look different): GRUB_CMDLINE_LINUX_DEFAULT='quiet splash nomodeset' Feel free to remove вЂњsplashвЂќ and вЂњquietвЂќ if youвЂ™d like text boot. Locate the line with the variable вЂњGRUB_CMDLINE_LINUX_DEFAULTвЂќ, and add вЂњnomodesetвЂќ to the variables.

Either вЂњsuвЂќ in to root, or use вЂњsudoвЂќ to open your favorite text editor and edit the file вЂњ/etc/default/grubвЂќ (I use nano which can be install by running вЂњapt install nanoвЂќ): nano /etc/default/grub.

Open a terminal window (Applications -> Terminal, or press the вЂњStartвЂќ button and type terminal).

Once the system has booted using the temporary fix, log in.

Feel free to remove вЂњquietвЂќ and вЂњsplashвЂќ for more verbosity to troubleshoot the boot process.

Move your cursor down to the line that starts with вЂњlinuxвЂќ, and use the right arrow key to find the section with the words вЂњro quiet splashвЂќ.

Once GRUB is open, press the вЂњeвЂќ key to edit the first highlighted entry вЂњUbuntuвЂќ.

If your computer uses EFI or UEFI, continuously tap the вЂњESCвЂќ (escape) key after turning on your PC.

After turning on your PC, hold the right SHIFT key to get to the GRUB bootloader if your computer uses a BIOS.

ItвЂ™s much like the issue I described here on a Fedora Linux system. This is due to a video mode issue that causes the system to halt or freeze. This event can also occur on a fresh installation or when updates are installed. After upgrading a computer from Ubuntu 16.04 LTS to Ubuntu 18.04 LTS or Ubuntu 18.04 LTS to Ubuntu 20.04 LTS, during boot the screen goes blank (turns black), all HD disk activity halts, and the system becomes frozen.
