Re: X won't give high-res with high colors
I don't know if this could help but if you are in a need for some non-standard modelines for X, trying to bypass some limitations, the following might help calculating such modelines: http://www.hut.fi/Misc/Electronics/faq/vga2rgb/calc.html http://zaph.com/Modeline/ http://koala.ilog.fr/cgi-bin/nph-colas-modelines Boaz.

Hi, It pretty much seems to be incorrect H and V frequencies detected.check XF86Config with manuals. Also check modes in XF86Config. behdad On Thu, 18 Sep 2003, Shachar Shemesh wrote: > Hi all, > > Sorry that this post is a little scarce on details.

Re: X won't give high-res with high colors
Hi, Could you give me the Dell model name and number please? To me, it seems it identied the amount of ram for X wrongly...

Re: X won't give high-res with high colors
If the GPU is NVIDIA, then you need to install their drivers, otherwise X (sometimes) detects it wrong and uses the nv driver instead of nvidia. If it's not nvidia gpu, then post what is the hardware specs and the x log, if poossible.

I'm not a real expert, but I think resolution detection works like this
(pseudocode):
foreach ( res in vesa_resolutions ) {
if ( monitor_supports( res, depth ) ) {
set_resolution( res, depth );
break;
}
}
if ( resolution_still_unset ) {
fail (X);
}
Although I think it also tries other depths in an outer loop if your depth
doesn't match, but I'm not sure.
I think your problem is that laptop monitors have resolutions that don't
necessarily match vesa standard resolutions, so you either have to give a
specific modeline (complete voodo), or hope that one of the monitor resolution
matches a vesa resolution. I would venture further to guess that the highest
vesa resolution supported by your monitor takes too much memory from the
graphics card to support full depth.

X won't give high-res with high colors
Hi all, Sorry that this post is a little scarce on details. I will fill them in when I have them again. I am installing Linux on my sister's laptop (a Dell centrino, don't have exact model). I went for RH9 because that's what would be fastest to install. It correctly detected almost everything (sound, display adapter). At least, I think it did. Everything seemed to work. However, when X is set up for 16 or 32 bits/pixel, the highest resolution available seem to be 640x480. Looking at the X startup log, I can see that the system detects resolutions of up to 1280x1024, but discards them all as non-matching (I did not manage to understand what it was they did not match).
