HiDPI settings are not applied upon login with nvidia proprietary drivers

[shigutso]

Ubuntu MATE 18.04 LTS x86_64
nvidia-396 drivers
1920x1080 display

On opensource drivers it works fine, but it seems that the proprietary nvidia drivers does something that prevents the HiDPI settings to be applied when a user logins.

Is there any way to fix that? Or at least is there a mate-tweak command line options to set HiDPI settings so I can automate as a workaround?

Also found this bug report with another workaround:

Scaling issues with nvidia

Hi, Is there anyway to adjust scaling in MATE 16.04? I've just switched gpu from amd to nvidia and everything ( panels, font, browsers) are far too enlarged. Using the x.org nouveau driver everything looked fine, but I can't get the same results with the proprietary drivers, which I installed via: sudo apt-add-repository ppa:graphics-drivers/ppa sudo apt-get update I've tried all of the available versions in software & updates, but the scaling issue abides in all except for Nouveau. Here ar…

But it’s not a very graceful way to fix things…
