Over at the CERN laboratory in Geneva, they have mandated a switch
from SLC3 to SLC5, their newest version of Scientific Linux. On SLC5,
all my Tk buttons are enormous because the system assumes a huge font
size. I can over-ride the system font with specific Tk commands, but
I'd rather fix the SLC5 system settings. The problem is, I can't
figure out which Linux font settings Tk uses.

Which environment variables or configuration file does Tk use to
obtain its default font sizes? Thank you in advance,

Did you try already the "option add" command?

On my Linux I had to minimize my tk_messageBox text. I did:

option add *Dialog.msg.font {Sans 9}

For your purpose would be suitable:

option add *Button.font {sans 9}

I'm typing this from SL5, and Tk buttons are normal. It sounds like
you simply have the dpi of your monitor misconfigured. Was your
monitor recognized properly when you installed? Can you check the
information in the monitor configuration gui? Try this:

wish
winfo screenmmwidth .

Does it report the actual size of your monitor?

It would really be great if someone would add some information about
the useful option arguments to the appropriate man pages or at least
wiki pages, to help when people are trying to accomplish things like
this.
