Upgrade to 15.10 failed to do video correctly. Video works with live 15.10 DVD. Multiple install and uninstall of several different NVIDA drivers and Nouveau drivers no help.
Want to do clean install, but need to preserve packages and settings. Aptik is GUI-oriented but does have command line options, but does not appear to do complete job.
What exists that will allow me to back up apps and settings, do clean install, then restore apps and settings?
OS is on one drive, Home directories are on separate RAID array; does this help?
