ubuntu 18.04 does not recognize intel graphics card after update
Just did a regular ubuntu update on a laptop.
Now in About>Details it says
Graphics: llvmpipe (LLVM 6.0, 256 bits)
It said "Intel Graphics (CofeeLake something...)" before the update.
Also gnome-shell cpu usage went significantly up now.
How to bring it back?
sudo lspci -v output (relevant lines):

Fixed, using steps 1 and 2 of the answer here:
Ubuntu 18.04 not working with Intel Integrated Graphics
It explains how to force Xorg to use intel drivers.
It is still a mystery why it stopped using them in the first place.
