[Bug 579895] Re: Resizing Multiple Times loses toolbar in KDE

[wvengen]

** Description changed:

+ KDE toolbar can disappear when dynamically disabling a previously
+ activated display. This was found while using disper to change displays,
+ but as it has also been seen with nvidia-settings, it's likely to be
+ related to KDE.
+ 
+ Original bug description follows:
+ ----------------------------------------------
  My disper version is disper 0.2.2.
  
  My configuration is such that at the office I have two external displays
  on this laptop.  1600x1200 and 1920x1080 .  I use the following command
  to enable those displays when I dock my laptop:
  
  disper -e -t left -d DFP-1,CRT-0
  
  At home I use my laptop screen and a single display which is 1600x1200
  and I use the following command to switch to that.
  
  disper -e
  
  When I undock from there, I may want to use my laptop screen only, which
  I use the command
  
  disper -s
  
  to activate.
  
  When I do this, my kde toolbar disappears below the bottom on the
  displayable screen, although my mouse will only travel inside the
  displayed screen, so it isn't a "Virtual Desktop" setting or anything
  like that.
  
  If I redock either at work or at home and run
  
  disper -e
  
  then the screen fixes itself and I can see my toolbar again.
  
  My output of disper -p when I am running on only the laptop screen and
  can't find the toolbar is as follows:
  
  $disper -p
  
  backend: nvidia
  associated displays: DFP-0
  metamode: DFP-0: 1680x1050 @1680x1050 +0+0
  scaling: stretched
  
+ I have had this problem ever since going to disper, and have had
+ multiple versions of KDE on this laptop, so I'm fairly certain this
+ isn't a kde issue.
