unity - 16.04 - Slow login, no wallpaper, missing image icons in taskbar - Ask Ubuntu


as of week ago, desktop has exhibited following problems - starting @ once.

  • after cold boot or restart reach login screen in normal amount of time, after entering password there's noticeable hitch, end on black screen mouse cursor.

  • if leave alone few minutes, taskbar , launcher appear.

  • besides taskbar , launcher, desktop remains black (as if there's no longer wallpaper set), computer otherwise functional.

  • all icons in top-right corner of screen have 'missing image' icon:

    taskbar

as far know didn't make configuration changes @ time, besides perhaps installing updates. here's system information; please ask if else helpful.

  • ubuntu 16.04 lts
  • unity 7.4.0
  • intel core i3 3.3ghz x 4 / 8gb ram
  • gallium 0.4 on amd turks (drm 2.43.0, llvm 3.8.0)

here think the log of last apt operation before started having trouble. right @ end shows error: sub-process /usr/bin/dpkg exited unexpectedly - i'm not sure in particular it's referring to, or how recover it.

thanks in advance!

i can't i'm of root cause here, re-updating seems have gotten things normal.

sudo apt-get update sudo apt-get upgrade sudo apt autoremove sudo reboot

my best guess based on logs went terribly wrong while updating window manager unity (7.4.0+16.04.20160906-0ubuntu1) @ least caused bunch of built-in assets go missing. upgrade fixed install.
