Title: Linux Framebuffer & 15kHz
Post by: DaRacerz on April 18, 2004, 10:25:14 am
Has anyone been able to acheive this?  Granted I haven't ran the advv or advcfg programs, I tried to set up my rc config file with the specs of hclock of 15.75, but when I load advmame, its not at that resolution.  I know because my regular computer monitor displays it fine, and two, the Arcade Monitor has 4 Pictures, lolol.

Anyways, anybody have a working config that I can paste out for me to check out?  Linux Kernel 2.4.22 using rivafb

BTW, when running windoze, it works fine, but I shall refuse to use windows.

The modelines you get from advcfg in DOS are compatible with XFree86 (http://www.xfree86.org/). You just need to make modelines first by using advcfg or you could create an approximate modeline using this page (http://xtiming.sourceforge.net/).

Note that the timing expressed in a modeline is specific to your video card and monitor combo. As such, you cannot use somebody-else's working modelines.

right now only matrox's g400 supports a 15kHz console.  while the rivafb driver works fine at 15kHz, you can't boot a 15kHz console.  Hopefully, this will change in the near future.  But for right now, the linux fb drivers aren't as stable as svgalib in DOS, so if you want a 15kHz console, you'll need to use a matrox g400.  If you use DOS, you shouldn't have any problems with your card..
