Comment 5 for bug 1876277

Thanks for the update.
To be honest, not sure if my issues were exactly the same as these two
bugs, they are are both for upgrades while mine is for a fresh install.
A lot of the discussion in this bug
https://bugs.launchpad.net/bugs/1867668 seems
to be focused on /etc/X11/xorg.conf.d/20-intel.conf, which doesn't exist on
my system.

Are there any bugs filed for graphic issues with a new install of 20.04?

Note, I've switched to Wayland and have seen a significant improvement.
There are still some issues, but they are much less frequent.

Regards,
