it's just a week that I upgrade to ubuntu 20.04 ( I was in 19.10 before).
I think I have a problem with the graphic card ( see this)
Today I found a new error when I restart the system. It seems that it occurs in the old version of Ubuntu, I have no found related question with the new version.
What could i do to solve this problem?
There are many posts out there with similar questions. I recall once having a problem (possibly the same) and solving with a change in GRUB:
Edit the default boot line (GRUB_CMDLINE_LINUX_DEFAULT) in /etc/default/grub, adding acpi=off nomodeset xforcevesa.
Then
$ sudo update-grub
$ sudo shutdown -r
