[Bug 1885474] Re: 1366x768 screen resolution broken, all other resolutions OK

[mike-g2]

I have the same issue.  As mentioned in reddit thread in OP, the login
screen displays properly at 1366x768.  I'm running MATE so I'm not sure
how to implement the workaround @johnnyl33-k mentions for Xubuntu since
there are no reflection options.  I will note setting rotation to
'upside-down' in Control Center->Monitor Preference does not suffer from
the tearing the 'normal' rotation does.  It's just hard to work upside
down!

Bug description:
  Hi,

  After upgrade from Ubuntu Mate 19.10 to Ubuntu Mate 20.04 i cannot use
  a resolution of 1366x768. Screenshot attached. I am using an Asus
  vivoBook laptop with Amd Ryzen 3 and a Radeon Vega Graphics AMD.

  I found someone in reddit reporting the same problem:
  https://www.reddit.com/r/UbuntuMATE/comments/ggq8g5/problem_with_resolution_1366x768_with_ubuntu_mate/

  All other screen resolutions OK.

  
  Many thanks
