Thanks Jamie It's a valid resolution, simply put it under Modes, Subsection Display, Section Screen. The only problem you should have are invalid VideoBIOS entries if your card is an i915. pgpPbDtraRIyL.pgp Description: PGP signature

I've only done this with CRTs, but it should also work with CRTs. You need to know the max and min frequencies (both horizontal and vertical) for your display. Knowing the card's max bandwidth helps, but isn't as critical. Since you're getting a new machine, you should have the manuals for the display and the card. Find those numbers and go to http://koala.ilog.fr/cgi-bin/nph-colas-modelines and fill in the numbers and it'll generate a whole slew of modelines for you. In your case the enter the desired screen ratio here: entry should be... 8/5 That's because 1680/1050 = 8/5 LCDs are lousy at interpolating resolution. They give optimal display when at their native resolution or a whole-number divisor thereof. E.g. 840x525 and 560x350 and 336x210 should be OK. You'd use them if you're watching streaming video. Cutting down to 560x350 and watching streaming video doesn't require the extra CPU power that software resizing requires for mplayer or xine. To get to the lower resolutions may require doublescan, which the above site doesn't do. A site for modelines with doublescan or interlace is... http://xtiming.sourceforge.net/cgi-bin/xtiming.pl but it'll only do one modeline at a time. Note 1) On an LCD, you can get away with refresh rates as low as 30 hz, and still be comfortable. On a CRT, 30 hz is murder on the eyes. Note 2) In an xterm, run the command xrandr -q for a list of available resolutions. man xrandr for details on how to change screen resolution on-the-fly. It does have a flaw in that programs don't recognize the changed resolution. I start up another xterm, resize it to 20 columns x 5 rows, and park it in the upper left corner. The panic button command to return to normal is xrandr -s 0. -- Walter Dnes [EMAIL PROTECTED] In linux /sbin/init is Job #1 My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list

X can obtain this information directly from the monitor and work out the rest on it's own. Simply specifying a 1680x1050 mode should be sufficient. -- Raymond Lewis Rebbeck -- gentoo-user@gentoo.org mailing list

Thanks Jamie How exactly is this non standard? It is a perfectly valid resolution, my laptop screen has the same resolution. You will most probably only have too add a 1680x1050 mode to the Screen section of your xorg.conf and possibly fiddle with the hsync and vrefresh settings if you have them set. It should just work, assuming your video card is capable of outputting that resolution, most are afaik. -- Raymond Lewis Rebbeck -- gentoo-user@gentoo.org mailing list
