everyone. My HP Pavilion G4 bought with suse linux OS, but when I change it to ubuntu, I couldn't find the drive softwave for linux(hp-drive-guard - HP DriveGuard; touch drive.....) would you help me, please?
I interpret your question as : how do I install additional drivers ?
Launch the "Software Sources" app. Go to the "Additional drivers" tab. Here are options to install new drivers.
Did my explanation help ?
