After repair from install disk Screen size shrunk and Desk top icons are way too large

Asked by bccynic on 2017-05-17

UBUNTU 16.04 I lost my sound and GRUB 2 were not working, and I am almost sure the speakers are okay GRUB2 still not working on start up without F12. Went to the install USB opened the grub repair and then other repairs.

When I opened UBUNTU the screen had shrunk in settings it says I am in 1024x768 (4:3) and the only option is 800x600 (4:3). My screen is 16x9 and the desktop picture is 3264x2448 and the icons on the desk are way too big.

bccynic Hello;

The output: " *-display UNCLAIMED " indicates the graphic's driver is not loaded.

Run terminal commands:
sudo rm /etc/X11/xorg.conf
sudo apt purge nvidia*
sudo ubuntu-drivers autoinstall

reboot and in terminal show us all is well .
dpkg -l | grep -i nvidia

- ain't nothing but a thing-

I got this as I found a broken ling which also fixed the problem except for the original sound problem which I think is actually the sound card in the computer.

Thank you yet again for all of your help, whenever I need it
