I installed Ubuntu 18.04 a day ago. It works perfectly but graphics is a problem; I see screen flickering where there are system or JS overlays and blurred text.
What can I do - my graphics are based on intel chip
Running sudo lshw -c display
I get
*-display

I think you'll need to give some more detailed hardware information here. Graphics devices should come up when you runlspci -knn | grep -EA2 'VGA|3D'orsudo lshw -c display. Can you edit your question to add that info?

To get rid of the flicker, I had to REMOVE these two lines from /etc/environment (you probably don't have them, unless you installed gnome-wobbly-windows extension)
CLUTTER_PAINT=disable-clipped-redraws:disable-culling
CLUTTER_VBLANK=True
And I also had to run sudo ubuntu-drivers autoinstall and then reboot
For nVidia cards:
To make the text non-blurry, I just increased the screen resolution via nvidia-settings (the Display dialog did not let me change the resolution)
