X and Fluxbox :: Hor & vertical synk



Hi; in dsl installed on hd how do I change the vertical and horizontal refresh of monitor?

thanks.

You can't.

The DSL tinyX Kdrive server uses 60Hz refresh only.

The Vesa2.0 video specification only allows for 60Hz refresh rate.

There is a Vesa Bios Extension 3.0 that allows the user to specify different refresh rates for newer video cards  (generally 1998 or newer) but the Xvesa server does not support them.

Your only options are to:

(1) Get the source code to the Xvesa server and rewrite the program yourself.

(2) Use  an MSDOS VBE setting program to set the default Vesa refresh rate to higher than 60Hz and then boot DSL using a utilitiy like linld.  Then choose the framebuffer server (non-accelerated and sluggish compared to Xvesa).

(3) Replace the Kdrive xserver with the "real" XFree86 Xwindows system.  For help, try searching the forum using the "Search" button at the top of this page. Then type in a keyword like "xfree86" or "xwindows", choose search ALL THE FORUMS and search FROM THE BEGGINNIG or NEWER.

Good Luck.
ok, thanks, but if i put xfree86 on dsl, it lost his charm... :)
Hi!

Silvio.
There is a workaround to avoid the 60 Hz refresh rate - when googling I found the following:

Refresh rates
=============
There is no way to change the vesafb video mode and/or timings after
booting linux.  If you are not happy with the 60 Hz refresh rate, you
have these options:
* configure and load the DOS-Tools for your the graphics board (if
  available) and boot linux with loadlin.
* use a native driver (matroxfb/atyfb) instead if vesafb.  If none
  is available, write a new one!
* VBE 3.0 might work too.  I have neither a gfx board with VBE 3.0
  support nor the specs, so I have not checked this yet.

I tried the first and it works - I am now running 640x480 at 72 Hz using a Tseng ET4000 card. The problem may be to find any dos tools ... (Scitech have some dos tools that may/may not work, http://www.scitechsoft.com/ftp/sdd/).

(Admittedly, I have tried this with Basic Linux 3.21, but as both use Xvesa, it should work with DSL as well. One problem though, you have to have a clean dos boot without accessing autoexec.bat or config.sys as Xvesa appearently won't work otherwise. Also look at the bottom of http://damnsmalllinux.org/cgi-bin....5;t=176 )
