unity - Desktop, icons, and x pointer after upgrading from 14.04 LTS to 16.04 LTS - Ask Ubuntu


having issue macpro 2008 after tried upgrading 14.04 lts 16.04 lts.

the initial thing noticed have having issue mounting lvm volumes, commented out in /etc/fstab

i used graphical login screen before upgrade, terminal when boots up. after login if run startx i'm presented looks unity or gnome, displays desktop had before, , black x mouse pointer. i'm able right click , open terminal there, , can select files on desktop, can't bring launcher , there no task bar.

i'd working can take @ lvm issues, idea of how fix this?

update: i've found if run compiz title bar on windows back, , i'm able drag around, warning warn: no default decoration found, placement not correct.

update 2: if run unity launcher back. none of comes automatically, noticed clock missing. i've got unity running appears can open ccsm, must dependency.

update 3: got webmin, , says i'm still running ubuntu 14.04.2, inconsistent splash login terminal reads 16.04.
