[Bug 1627348] Re: Live DVD boots to black screen with mouse pointer

[Lars Bischoff]

I could reproduce the exactly same behaviour now also within a VirtualBox session!
See also updated description.

** Description changed:

  I've tested booting from the Kubuntu 16.10 beta ISO on a
  Acer Travelmate 290, 1,8GHz Pentium M, 2GB RAM, Mob. Radeon 9700 Gfx.
  
  System boots fine until the selection of "trying" or "installing" Kubuntu.
  If I select "try", system continues, finally shows the KDE login splash, then ends up with a black screen and visible mouse pointer.
  
  Plasma seems to be active though: Moving the Mouse to the upper left
- edge highlights the active corner.
+ edge highlights the active corner. But there is no pop-up menu on right
+ click.
  
  If I now press the power button, the log out dialog shows up. Confirming
  that, the log in screen is displayed.
  
  If I now login again, I end up with an empty KDE Desktop, no panel.
  After adding the default panel manually I can work as usual with the
  Live Session.
+ 
+ Update: I could reproduce the exactly same behaviour now also within a VirtualBox session! 
+ I've used the "Ubuntu(32bit)" OS setting and 2GB of RAM for the guest.
+ 
+ BTW: Using 4GB RAM the behaviour is a bit different:
+ Instead of a fully black screen, I get a black screen with panel.
+ But still no pop-up menu on right click. A click on the Panel's App launcher leads to a crash and restart of plasma. After that Plasma seems to work ok.
+ This behaviour I also observed on real 64bit Hardware, when booting from 32bit ISO.
