Alexandre S's questions

I was trying XFCE 4.14 on Ubuntu 20.04, just to see how it was. After that, I've completed removed it and all it's packages and came back to GNOME shell. Suddenly, I realized that the New Tab "+" icon and Search icon were gone from the title bar. This is how it looks like now

Before, the title bar looked like this (image from internet, so it has a different theme)

How to I get my title bar back the way it used to be? PS: I can't find an option to revert thins on "preferences" windows from GNOME Terminal

I'm using Ubuntu 20.04 with a NVIDIA MX250. Firstly, nvidia-prime was not working. Even when selecting nvidia only, it was using Intel HD Graphics.

I've forced the use of NVIDIA as the primary GPU by creating /etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf with: Option "PrimaryGPU" "yes" (seen here https://wiki.archlinux.org/index.php/NVIDIA_Optimus).

This works, now nvidia-settings show all options (before was showing only prime options, and nothing more - even when selecting NVIDIA Only).

But now, fractional scalling crops half of the screen. The funny thing is that when I try to printscreen, on the picture it looks fine, but in reality is not. I had to make a photo with my cellphone. As you can see, elements don't fit the screen (Note firefox title bar, for example).

I really need fractional scalling, because everything is really small. KDE works fine, but I don't like it. And font scalling is not really good.

Thanks!

I'm trying to configure my touch-pad gestures in Ubuntu 19.10 and xdotools doesn't work properly when I switch between different keyboards layouts.

I've found in this post how to launch Activities Overview from command line.
Invoking GNOME Activities overview from command line.

But I would like to do the same thing with the "Applications" grid in GNOME shell.
