Ubuntu 10.04 & docking station part 2

As you might already know, I am using my Ubuntu laptop also with a docking station and external monitor. When I am in the office I dock it in leaving it closed and use only the external monitor (that is by the way a behaviour I can see at several customers also - having no fixed machine any more and dock in the closed notebook).

I had an issue I already described earlier - see part 1: Ubuntu 10.04 with docking station.

Since then I had several issues of having TV1 noticed by accident even when doing nothing or same with my internal laptop screen (LVDS1) when I am working with the external monitor only. The annoying things are three when this happens:

• I can accidently move the mouse out of the window taking a while to bring it back.
• In my compiz I have defined that right-clicking on the border of the screen switches to the next desktop. That does not work any more as the border is not reached when I move the moust to the border of the visible screen.
• Windows may be displayed on the invisible part of the screen so I have them in the task bar but don't see them on screen.

Now I am pretty sure that it is the screensaver that is the culprit here. Disabling the screensaver never brought the issue back again. Only drawback: When I leave the machine I manually have to lock the screen pressing CTRL+ALT+L.

Same thing of second monitor accidently recognized happened in about 75 % when starting TeamViewer (which is my favorite remote assistence tool). Today I finally filed a bug and guess what - problem already solved (thanks to Daniel Stiefelmaier at TeamViewer support)!

Dear Martin,

I found a possible solution to that. Please open a console and run
WINEDEBUG=xrandr teamviewer&
Then take a look at the log:
cat ~/.teamviewer/6/winelog
You should see some xrandr lines. Then run
/opt/teamviewer/teamviewer/6/bin/.regedit
Create the key HKEY_CURRENT_USER\Software\Wine\X11 Driver
there, create a String "UseXRandR" and set its value to "N".
Close the registry, and repeat the other commands:
WINEDEBUG=xrandr teamviewer&
cat ~/.teamviewer/6/winelog
Now, there should be no xrandr lines.

Yeah, that did it!
