I did what you said, but it seems I didn't get the expected results:
Video adapter: VESA VGA Mode: COLSxROWS: 0 0F00 80x25 1 0F01 80x50 2 0F02 80x43 3 0F03 80x28 4 0F05 80x30 5 0F06 80x34 6 0F07 80x60
Those are good. But now that I see them I remember that they are for virtual consoles. I don't recall that they would affect the system-config-display actions.
Regardless, you can pick one at boot time if "vga=ask" (without the quotes) and you'll see different character sizes. If you code "vga=xxx", where the "xxx" is one of those codes, they must be converted to decimal first. One of those links I posted later has a link to how to do that.
But, as I mentioned, I now don't think this will affect the X setup.
No, it don't affect.
So, no graphic mode as I could find by googling http://tldp.org/HOWTO/Framebuffer-HOWTO-5.html
This link only has effect if you're using framebuffer. That's (IIRC) optional - I have it on my 4.x system, but I set it up a long time ago and would have to research to recall the details. It gave a nice speed improvement.
I found several links: http://www.tkk.fi/Misc/Electronics/faq/vga2rgb/calc.html http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
Unfortunately, I can't find the dot clock for the driver as I can't find the video controller model "ATI Technologies Inc M71 [Mobility Radeon X2100]" on the ATI website :-(
Anyway, it's not mandatory. If you want to use it, more setup steps are needed. I would skip it now and continue what you're doing - get a basic acceptable setup running.
If I use, as an example, vga=0x307, when I startx, I can see saying 4 desktops
As I mention above, I think the hexadecimal needs to be converted to decimal. It's been a _long_ time, but I _think_ 0x307 = 775 decimal. But I don't remember if that value is big-endian or little-endian. Big, I think.
Both notations, decimal and hexadecimal, are allowed.
on the width of the screen and height of these desktop are only 1/10 height on the screen, at the top of it So, 9/10 of the screen is black.

I saw that another posted some parameters to try with system-config-display. I'm going to peek at that and see what else I might offer.
I might save my configs and play with system-config-display a bit and see if any clues pop up.
Thanks!
