I fixed my issue (It might also help someone resolve this issue on a
deeper level)
This probably won't be a solution for most people because I have
kubuntu-kde4 installed on an external usb device that I ONLY use when
hooked up at home via a KVM switch to an external monitor. In the event
that you WILL NOT use your internal LVDS monitor for kde4, you can do
the following to make the desktop on the external monitor work properly:
Back up your /exc/X11/xorg.conf
run in konsole, while logged into KDE4 with YOUR EXTERNAL MONITOR
ATTACHED.
sudo dpkg-reconfigure -phigh xserver-xorg
Make sure your /etc/X11/xorg.conf has a similar addition: I had to add:
Option "monitor-VGA" "SyncMaster"
Option "monitor-TV" "TV"
Option "monitor-LVCD" "LVCD":
and associated monitors
Example:
Section "Device"
Identifier "Intel Corporation Mobile 915GM/GMS/910GML Express
Graphics Controller"
Driver "intel"
BusID "PCI:0:2:0"
Option "monitor-VGA" "SyncMaster"
Option "monitor-TV" "TV"
Option "monitor-LVCD" "LVCD"
EndSection
Section "Monitor"
Identifier "SyncMaster"
Option "DPMS"
EndSection
Section "Monitor"
Identifier "TV"
Option "Ignore" "true"
EndSection
Section "Monitor"
Identifier "LVCD"
Option "DPMS"
Option "Ignore" "true"
EndSection
Then add this to the beginning your /home/user/.bashrc
xrandr --output LVDS --off
You can leave it at that and log in/out and the panel is fixed, but
anything in the system tray won't show and your desktop will still look
weird,
so if you are willing to LOSE YOUR DESKTOP SETTINGS:
while logged out of KDE4 so rename your old /home/user/.kde4 directory to
something (i.e. .kde4old), then log back in.
