Title:
Screen flickering
Status in xorg package in Ubuntu:
Confirmed
Bug description:
To whom it may concern,
As stated I have screen flickerings (see lightning like flickering on photo
attached for portrait screen, for horizontal screen I also have screen
flickering on the upper part but hard to catch in a photo) on freshly installed
Ubuntu 20.04 LTS.
I have tried this:
https://askubuntu.com/questions/1231441/ubuntu-screen-flickering
and this:
https://learnubuntumate.weebly.com/screen-tearing-on-intel-
graphics.html
without success. I have also seen some other people mentioning screen
flickering on ubuntu 20.04 here:
https://www.reddit.com/r/Ubuntu/comments/fvk536/anyone_else_noticing_window_flickering_on_ubuntu/
without solution.
I also know that it is very unlikely hardware problem because my screens were
displaying well on archlinux. I think my graphic card info are already included
in the report but just in case: Intel Corporation UHD Graphics 630. Might be
intel driver problems ?
Could you help me on this please ?
Best regards,
Jeremy
