20.04, effectively a kubuntu system. User 'adam' (/home/adam) uses a KDE Plasma desktop. User 'glen' (/home/glen) uses a Gnome MATE desktop.

For example, the files & subdirs on an external HD/partition '/extra' is entirely assigned to user 'adam' with owner 'adam'. I'm not making 'adam' with its /home/adam go away. But I want to change which user is utilized daily, which will eventually be 'glen'. Is there a guided ..read more

Hi friends, fresh installed Ubuntu bare metal 6xNICs machine, new network profile for any of the nics creates a new profile for ALL the nics. The problem is all the network settings are copied to all the nics. I mean when you have an ethernet card every interface has different network settings but here does not work in that way. If i delete that profile in one of the nics, then it dissapears not only for that interface but for all interfaces. No way to create a new profile only for one of the nics, the profile is created for all of them at the same time, and the network settings for that new p ..read more
