I use Ubuntu 20.04.1, Gnome 3.36.3 on Lenovo ideapad L340 (UEFI, Dual boot with Win10) GeForce GTX 1650 with nvidia-driver-440
My desktop UI (top bar, popups, Applications screen) and login screen are twice larger that they should be. But all other applications work correctly.
To fix this problem I tried:
To use open source driver - the problem is fixed, but I have very low performance with this driver.
To run with grub option acpi=off - the problem is fixed, but there's a lot of critical issues appears.
To set display scale to 200% and than revert - the problem is fixed until restart.
To reinstall Gnome with commands
apt purge gnome-shell apt install gnome-shell ubuntu-gnome-desktop
nothing is changed at all.
Do you have any ideas how to fix this?
