In Precise, window auto-maximize is disabled on monitors with a resolution above 1024 × 600 . I have a bigger resolution, but I prefer maximized windows anyway. I want Update Manager to start maximized.
What I've tried so far:
- In Compiz Config Settings Manager, I have Place Windows activated and 'Windows with fixed placement mode' has windows matching the rule "(name=gnome-terminal) | (name=update-manager)" set to 'Maximize'. With this, Gnome Terminal starts maximized, Update Manager does not.
- In Compiz Config Settings Manager, I have set a Window Rules  rule to match "name=update-manager". Irregardless of any rules set or not, activating Window Rules results in not being able to bring out Unity Launcher anymore, Alt+Tab window switching becoming slow or nonfunctional entirely and the screen sporadically freezing completely. Not a viable option apparently.
- I've installed Maximus  and started it. Update Manager ignores it (or vice versa).
I've not tried devilspie and would prefer not to. Having to configure something external for this would seem stupidly redundant with (the no-brainer) Maximus and all these Compiz options already available. I just can't seem to make them work.
