Trying to start a PrimeHunt on a Linux box, but can't find the
Gnome switch/requeste(o)r to get the screen resolution down enough
so I can read without a microscope. Can anyone help? Am running
Redhat 6.1 with a VooDoo 3500 GFX card.
Presuming you're running in an xterm window, try holding down a control
key and pressing & holding your third mouse button while in that
window; xterm should bring up a list of font sizes. Simply release the
mouse button while the mouse cursor is on the one that you want to try.
This means that each xterm can have a different font size, if that's
what you want. The font, including size, can also be given on the
command line, as in 'xterm -fn 9x15bold' (e.g.). 'xlsfonts' will list
the fonts your X11 server knows about, but it's usually a very long
list, so you probably want to redirect it into a file ('xlsfonts >
file') or something similar ('xlsfonts | more', perhaps).
Setting the font you want so that new xterms start with it is somewhat
messy, usually involving your ~/.Xdefaults file, but there may be a
configuration tool in Gnome that I'm not aware of (I was using X11
before Linux was created, let alone before Gnome, so ... :).
Some X11 configurations, usually declared in /etc/X11/XF86Config,
support more than one video resolution, which is usually changed while
running X with control-alt-(keypad's + key) and control-alt-(keypad -).
These support virtual screens in that the pixels that fit within the
display area are only part of what X11 is actually displaying; simply
try to move the mouse off the edge of the screen towards what you want
to see that's off the edge. The size of the virtual screen is only
limited by the amount of memory your video card can access and the
color depth (256 colors fit in 8 bits, e.g., as Mersenne hunters
should know :).
