Hello, 

On a Powermac 7300/200 I thought I might try using the 
tvtwm window manager as a workaround for Xmacppc's 
640x480 limitation.  

Is there a better workaround than tvtwm (aside from 
installing a video card)?

I am using NetBSD-1.6.  When I run 

# startx 

Xmacppc seems to run just fine using twm.  This is 
out-of-the-box without any configuration.  I built 
tvtwm from pkgsrc/wm, but I don't know how to tell 
Xmacppc to use tvtwm instead of twm.  

# man xmacppc
man: no entry for xmacppc in the manual.
# man Xmacppc
man: no entry for Xmacppc in the manual.
# exit

How to I tell Xmacppc to use tvtwm?  

Is there Xmacppc documentation?  If yes, where?  

Thanks! 

Tom
