I bough a dell xps 13 7390 a few days ago. I installed Ubuntu 18.04. Everything is perfect, but the only problem is, the screen resolution is showing just one option using x11. I searched for this problem a lot but could not find a good solution. Although I did find one solution Screen resolution not showing all options on 18.04 it did not fix the problem completely. I want to be able to get all the screen resolutions. Is there any way to get all the resolutions? Or is something wrong with the graphics card?This is what the settings display panel shows
This is what shows on my 2015 macbook pro running ubuntu 18.04. I want all these resolutions
When I run lspci -v -s $(lspci | grep ' VGA ' | cut -d" " -f 1)
this is the result I get
