Calibration Messages Are Unreadable
The Calibration program attempts to use a Helvetica font. If not found, it uses a
relatively random font. This font may be unreadable.
To override this behavior, set the symbol MT7FontSanSerif to a proper X Windows font
name. To find a suitable font, use the xlsfonts command or other suitable utility that
lists the available fonts. In a command prompt, set the symbol, export it, and run the MT
7 calibration utility TwCalib. Experiment with the value of MT7FontSansSerif until the
calibration text is suitable. For example, if MT 7 for Linux® is in /etc/twscreen, a
test sequence may be:
MT7FontSansSerif="-*-utopia-*"
export MT7FontSansSerif
/etc/twscreen/TwCalib
You can also test your font string with xlsf onts. After setting MT7FontSansSerif, issue
the command xlsfonts -fn $MT7FontSansSerif to see what font, if any,
matches.
If you find a suitable font, change your system login script, such as
/etc/profile.local, to set and export MT7FontSansSerif.
