Hi [member=7067]JanetBiggar[/member]

What is GUI? and where do I find it

GUI stands for Graphical User Interface, I don't know exactly which GUI he's referring to though, unless by GUI he meant the desktop, but again, I don't know.

Is this pc an Acer Aspire 5000? This one uses a SiS Mirage 2 graphics processor, you can check that by running on your terminal

Code:

$ lshw -numeric -C display

The lshw command above will show relevant info about the GPU.  According to this post https://ubuntu-mate.community/t/support-...lease/3378 it seems Ubuntu 16.04 doesn't support these ones, it's 2005 old, although someone else posted a solution here https://ubuntu-mate.community/t/set-sis-...16-10/3553. You could try that and see if that works.

In case you feel like trying the solution above, that was implemented in a Mate desktop while LL uses XFCE desktop, so instructions change for some steps as follows:
1. - Go to > Applications > Accessories > Leafpad  and paste the following text in the new file:

    Section "Device"
      Identifier "Configured Video Device"
      Driver "vesa"
    EndSection
Now click on "File > Save as" and give it the following name:
use-vesa.conf

2. - Open thunar and navigate to this directory /usr/share/x11/xorg.conf.d

3. - Rick-click on an empty space inside the folder and select "open as administrator or root"  - can't remember the exact option name and my system's in spanish - A new window will open in root mode, copy/paste the use-vesa.conf file you just created, close all windows and restart your PC. According to the author and people's comments you should now have a res of 1024x768 without the need for other drivers.

Hope this helps!
