Title:
Ubuntu 20.04 Fractional scaling
Status in xorg package in Ubuntu:
New
Bug description:
I have 2 screens
1 x 1440 x 2560 (2k)
1 x 3840 x 2160 (4k)
I just upgraded to ubuntu 20.04 (From 19.10). I have tried to use the
fractional scaling option and it seem its not working. When setting
the fractional scaling on the 4k monitor (to 125% or 150%) it glitches
out (Goes black) and when it comes back it has set the scaling to 200%
and changed the screen positions to be on top of one another, Seems
there is no way for me to set the correct scaling.
Just for information purposes I am currently using the nvidia-435
driver (I have also tried with the nvidia-440-driver) to no avail
