I recalled getting some help here from users who use Linux and Windows.

I am using Ubuntu Mate.

I am using a Canon TS9120 scanner/printer.

Also installed the official drivers.

The scanner program scans ok, but has no way to change the resolution.

When I try to install Scangear, it says

To install software, you must be logged in to an admin account. It says to remove the cd and log as an admin.

Is there a workaround?

Thanks.
