David Thanks for your help, this solved my problem. I did however need to figure out how to connect my computer to the internet: (additional help from https://serverfault.com/questions/21475/starting-network-connection-from-ubuntu-recovery ) I did open my sources.list file but there was no need to add "contrib" and "non-free" as these were already in the list.
# ip link this returns the name of the ethernet on my machine it was enp2s0 # ip link set enp2s0 up # dhclient enp2s0 # ip addr this now shows that I have an ip address on my network given by my router Then run # apt install firmware-amd-graphics Reboot and life is good now :-) Regards, John Figie On Tue, Oct 27, 2020 at 7:01 AM Greg Wooledge <wool...@eeg.ccf.org> wrote: > On Tue, Oct 27, 2020 at 01:18:42PM +1100, David wrote: > > You need to install the firmware. > > You do that by running this command as superuser: > > > > # apt install firmware-amd-graphics > > You may have to add "contrib" and "non-free" to your sources.list first, > and then run "apt update". > > See <https://wiki.debian.org/SourcesList#Example_sources.list> if > you need instructions for editing the file. > >
