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 

ridwan@ridwan-XPS-13-7390:~$ lspci -v -s $(lspci | grep ' VGA ' | cut -d" " -f 1)

    What type of graphics do you have? Doesn't the XPS have Nvidia or something? Did you already run sudo ubuntu-drivers autoinstall – mchid Mar 12 '20 at 23:51

    https://www.dell.com/support/home/us/en/19/product-support/product/xps-13-7390-laptop/drivers shows an urgent BIOS update is recommended. Also, https://www.dell.com/support/manuals/us/en/04/xps-13-7390-laptop/xps-7390-setup-and-specifications/video shows you could have multiple different Intel CPUs in an XPS 13 7390. Which is in yours? Please also run lspci -v -s $(lspci | grep ' VGA ' | cut -d" " -f 1) then click [edit] and paste the result into your question so all the facts we need are in the question. Please don't use Add Comment, since that's our channel to you. – K7AAY Mar 12 '20 at 23:53
  • This is the result I get when I run 'sudo ubuntu-drivers autoinstall'

  • @K7AAY thanks for the suggestion. I updated my question – Ridwan Rahman Mar 13 '20 at 00:02
  • Are you using X11 or Wayland? – ben rudgers Mar 13 '20 at 00:27
  • @benrudgers i am using x11 – Ridwan Rahman Mar 13 '20 at 00:52
  • To my surprise, I also see only one single option on my identical Dell (Ubuntu 19.10). Never noticed this before. Did not consider this as a problem, though, thus far, because it is the native resolution. – vanadium Mar 13 '20 at 12:40
  • @vanadium its actually alright but I just want the cross icons to be a bit bigger. Any idea if I can use some other programs for that? – Ridwan Rahman Mar 13 '20 at 12:45
  • What are the "cross icons"? You will have more luck solving that particular issue by asking it directly in a new question instead of asking it through a way you think might solve it. – vanadium Mar 13 '20 at 12:51
  • @vanadium i meant the close buttons of every program. yeah I think I might use it the way it is for a few months then lets see if someone finds a solution – Ridwan Rahman Mar 13 '20 at 23:19
  • This is where it is a pity that fractional scaling is not possible yet, except for experimental implementation in Wayland. You can give Font Scaling in Gnome Tweaks a try to give the impression of a larger interface. – vanadium Mar 14 '20 at 12:03
