Today my desktop wouldn't load budgie. I got this message failed to start liggtdm. service. I had previously been having problems getting my HP printer to print Tried various suggestions to no avail so switched computer off as was getting fed up of putting password in all the time! Booted up again later and got the above-mentioned message. Went to my laptop and to my horror this didn't boot up properly either. They are not connected on a network. Same message only with an additional message failed to start udisks2. service. Can anyone help me fix? Please use simple terms. I don't understand why both are affected. Thanks
