No lowres modes when using XF86 4.2.0

[villerk]

How can I obtain lowres modes (like 400x300, 512x384, 320x200) with XFree86 4.2.0? I remember that 3.3.6 automatically inserted the needed modelines to XF86Config. Do I need to write them myself this time?

I'm running Slackware 8.0, XFree86 4.2.0, Matrox Millenium G450 DDR DH.

Yup, just modify your /etc/X11/XF86Config-4 and add the lines in the proper section of your "Screen" settings.
Like so...:

SubSection "Display"
Depth 24
Modes "1600x1200" "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480" "512x384" "384x256@75" "256x224@75" "704x480@75"
EndSubSection

Of course I'm not sure if you need the @75 after some of the resolutions. I saw it on a forum for adding resolutions for playing mame games. Laters.

Well, this is the point. I tried to do that, but X just said "mode not available". (Can't remember just now what it said, I'll put the exact info here later). Anyway, that didn't work. With the modelines I talked about earlier I really meant these:

Modeline "512x384" [lots of numbers]

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-107
VertRefresh 50-160
Option "DPMS"
ModeLine "512x384" 21.70 512 544 600 632 384 386 402 404
ModeLine "384x256@75" 20.107 384 392 464 472 256 257 262 284 Doublescan
ModeLine "256x224@75" 11.856 256 264 312 320 224 225 229 247 Doublescan
ModeLine "704x480@75" 32.421 704 720 840 856 480 481 485 505
EndSection


That's from my XF86Config-4. That SHOULD enable the modes you're looking for. Though you may have to tweak them a bit with Xvidtune. (in fact I need to do that myself, as I've noticed in Xmame that it's moved over to the left of the screen too far in certain games, I've just been too lazy to fix it.) Of course you'll want to tweak them anyhow for your specific monitor. I have a 21" monitor that will do 1600x1200@95 hz. If you need help with Xvidtune, I'll be glad to help. Good luck.

Thanks, this is just what I was looking for. I'll go check these out.

(Actually I found a HOWTO conserning this matter, so I'll be using it too).
