I have laptop with 18.04 installed, this problem also occurred when I used 16.04 before.
My screen seems to blink when I start typing, it blinked instantly that I could not capture the moment of it, anyhow the blinking also happens randomly, there is no pattern at all.
I have tried the suggestion from various source, this includes:
- Updating the kernel, I am using kernel 4.19 now, before this I was using kernel 4.5 or 4.6 but does not work also.
- Updating graphics driver, running command from https://askubuntu.com/a/215967. Doesn't seem to work, the flickering still happens.
How do I stop this from happening, it is not really distracting because it's only fraction of second, but if I can stop it I rather do so.
I don't have dedicated video graphics card, using Intel graphics at the moment. I think it's Intel HD 3000.

If you want further command, I'd love to include them.
