LINUX FIX: Gigabyte 990X - USB 3.0, 2.0 and Ethernet disabled after Ubuntu install.



After installing Ubuntu on my new computer I realised that only two of my USB 2.0 ports were working an non of the USB 3.0 ports or Ethernet network card. This seems to be a problem with many similar Gigabyte boards to mine. However there is a quick easy (revealingly so) solution to this.

In terminal run the following command: sudo nano /etc/default/grub
Find the line GRUB_CMDLINE_LINUX="" and replace with GRUB_CMDLINE_LINUX="iommu=soft"
save the file
open up another terminal and run: sudo update-grub
exit and restart computer


After applying this, every port; both 3.0, 2.0 and ethernet should work perfectly.
