Title:
  [i945gm] Strange interaction xrandr and KDE4

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: x11-xserver-utils

  I'm using my notebook docked (in the office) and alone at the home. I have 
connected 2 external monitors if is docked and I use two attached short scripts 
to switch output between both (dual-head) external and internal LCDs. There is 
really strange interaction between xrandr and window manager (?) - look 
attached pictures:
  1) xrandrDocked.png: There is only one little problem - the panel doesn't 
maximize his width. It happens when notebooks wakes up from RAM. If is docked 
during boot that is all right. I run script dualHeadOn manually after loggin to 
KDE session
  2) xrandrSwitchToInternal.png: I ran dualHeadOff script. Pictures shows how 
windows was transformed to new resolution. Sometimes it is done correctly 
(maximized windows remain maximized), but usually not. (Small rectangle in the 
upper left corner is FireFox ;?))
  3) xrandrSwitchToExternal.png: This is the opposite direction - I ran 
dualHeadOn. That the problem occurs every time, I'm afraid
  - I have enabled Auto-hide properties of the panel. This behaviour is on/off 
randomly
  - some icons disappear from the System Tray (like nm-applet, Skype). Non-KDE 
- maybe?
