Zorin os 15 ultimate

hi to everybody,

i'm new on this forum. I bought zorin 15 ultimate few days ago but i'm having some problem after the installation... The monitor blink with rgb color...

The pc is an HP all in one pro one 400 g3. The graphics card is an intel hd grahics 630 rev 04.

thanks in advance, lorenzo

There is mention of an i915 bug in earlier versions of Ubuntu (Zorin 15 is based on Ubuntu 18.04.2) - just wondering if adding nomode set at some point in the boot parmaeters may resolve issue?:

Hi Swarfendor437, first of all thanks for the answer.

I giva a look at your link and i can boot my pc in 1024x768 resolution but i'd like to use the max resolution... any other idea? i have the same problem with debian 9 (monitor flashing), in deb 8 instead i have a low resolution... i am desperate.... i have run out of resources....

Nieso, have you performed a dist-upgrade in terminal and also checked updates for Xorg?
