Public bug reported: [Regression]Unity shows blank desktop with software renderer
[Summary] Ubuntu 16.04 LTS shows blank desktop under software renderer (llvmpipe) after updates to improve low graphics mode. (LP: #1598770) [Expected] Unity Desktop [Actual] Unity wallpaper and not much else. Launcher and panel missing, windows are immobile, no task switching. Right-click context menu works and can open terminal. [Additional] Observed on Ubuntu guest VM running on Windows 10 Pro host (Hyper-V). Resetting unity and compiz settings doesn't seem effective. The problem occurs whether low graphics mode is enabled in CCSM or not.
