What determines the visual size of a given console font?
I have two computers, one with an i815 onboard video chip and the other with an i915. A console font that is perfectly readable on the former appears only half-size on the latter, requiring me to use a larger font size. Can anyone explain to me why that happens?"I'm just a little old lady; don't try to dazzle me with jargon!"

My experience with several ancient HP machines with i815 graphics is that they'll fail to recognize VGA mode numbers, but depending on the bootloader you may be given the option to manually choose one of its modes. In all cases, the VGA resolution is 640x480, but the font size varies so you can get anywhere from 80x25 to 80x50.
I'm not sure about i915; maybe it recognizes VGA mode numbers fine. In that case, I'm pretty sure most vaguely modern linux installs will try to choose the best resolution that the detected monitor can accept. That might typically be be 1024x768 or 1600x1200. This means a particular font will appear much smaller than at a 640x480 resolution.Isaac Kuo, ICQ 29055726 or Yahoo mechdan

I have partly solved this. The i915 has kernel mode switching and if you have this activated, you automatically get a framebuffer device built into the kernel. It's compulsory; you can't deselect it during the build. I remember playing about with optional framebuffer consoles last year and noticing that they shrink your fonts. I'd still like to know why, if someone can explain it to me in simple language.
I have set "vga=ask" in LILO and I'm trying out different options each time I boot but so far without noticing any difference. Annoyingly Crux doesn't include a console font large enough to compensate so I copied over the one I use in AntiX (16x28) and I've set that as my default font from now on."I'm just a little old lady; don't try to dazzle me with jargon!"

Hazel, there are stty settings that in your case should let you resize the fonts on the console. From the stty man page:
Control settings: [-]clocal disable modem control signals [-]cread allow input to be received * [-]crtscts enable RTS/CTS handshaking * [-]cdtrdsr enable DTR/DSR handshaking csN set character size to N bits, N in [5..8]Sometimes, real fast is almost as good as real time.
Just remember, Semper Gumbi - always be flexible!
