I had a dead mouse wheel in LTSP.  Read the docs at xfree86.org.  Logitech 
needs a mouse protocol of "MouseManPlusPS/2" (!) to get the wheel working.  
Made this change to lts.conf and had glory.

Had a "stuck" video resolution.  Read the full installation doc at ltsp.org.  
I was using the 2.x X_RES directive, which has become the X_MODE directive 
now, and it works much better (both my machine and the directive in general!)

I have a better gripe about the non-function of monitor power saving.  
Had to stare at the docs on xfree86.org.  XFree86 4.x needs:

Option "DPMS"

placed in the Monitor section, or you will never get your monitor to suspend. 
 So they say, and it is true.

I did a quick hack, and edited /opt/ltsp/i386/etc/rc.setupx to include a new 
line echoing the needed Option line to the final /etc/XF86Config file.  Sure 
enough, this works- for me, as I have only machines that have Energy Star 
compliant monitors attached.

There must be a directive, something like X_DPMS_CAP, to say whether any 
particular machine using LTSP is or is not equipped with Energy Star.  As it 
stands now, put just one old monitor "out there" and you lose power saving 
everywhere!

A similar quick hack can be seen in the 'ZAxisMapping' business.  Everybody 
gets "Option ZAxisMapping = "4 5" put in their [Default] section of lts.conf, 
whether they like it or not!  This does not work with some high-end mice, 
that have six buttons and need "5 6" here instead!

My quick hack is OK, putting it into the official distribution- not so good.

Cheers.
