Since there is no feed back Aren't character modes built into displays a thing of older displays and terminals? I thought that when a modern video card is in a text mode, it is actually rendering bitmapped text characters to a bitmapped frame buffer, which then gets sent to the display like any other image at that given resolution? But this resolution is limited to that which the card uses and going beyond that would require a software controlled text to high-res frame buffer? Shane J Pearsonshanejp netspace net au -|
Re: higher resolution on tty
Is there a way to programmatically detect whether the hardware supports a particular character mode? I know there's no query option is wsconscfg; will the driver know enough to bail, or is just a trial-and-error scenario? --david On 2/12/06, J.C.

Since there is no feed back from the latter (other than *you* looking at the screen), there's no way to tell if a particular character mode works (completely). Personally, I keep it simple and just stick to the defaults. JCR -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting.

higher resolution on tty
Hi list, i want to set up my screen resolution on tty to 1024x768 and smaller fonts, because i only work on tty on this maschine and this big fonts are a very bad on a 10,4 display. So is there a way to get this work. Because i don't find anything in the FAQ and with google. mfg eSpo
