As of about a week ago, my desktop has exhibited the following problems - all starting at once.
After a cold boot or a restart I reach the login screen in a normal amount of time, but after entering my password there's a noticeable hitch, then I end up on a black screen with only a mouse cursor.
If I leave it alone for a few minutes, the taskbar and launcher finally appear.
Besides the taskbar and launcher, the desktop remains black (as if there's no longer a wallpaper set), but the computer is otherwise functional.
All the icons in the top-right corner of the screen have a 'missing image' icon:
As far as I know I didn't make any configuration changes at the time, besides perhaps installing updates. Here's some system information; please ask if something else would be 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 is what I think is the log of the last
apt operation before I started having trouble. Right at the end it shows
Error: Sub-process /usr/bin/dpkg exited unexpectedly - but I'm not sure what in particular it's referring to, or how to recover from it.
Thanks in advance!
