Dual Monitor
 
Well I installed Mandrake and everything went fine except for my dual monitor setup, Both screens were at 800x600 and spanned. The huge problem was though that the left part of the screen was my right monitor and the right part of the screen was my left monitor (not fun at all).

So now I have it configured so that only my Geforce card is working and the Matrox card is ignored.

Now how, if its possible, to set it up like this

Main Monitior: Geforce2MX at 1280x1024 at 32bit color
Secondary Monitor: Matrox at 800x600 at 32 bit color

Thanx for all the help in my last thread, other then this problem the install went fine.

BTW, I hope to use KDE

I'm assuming Mandrake 8.0 or higher as this will only wirk with XFree86 4.x.x:

You will have to run /usr/X11/bin/XFree86 -configure and let XFree determine the BusID of your cards, also get the horiz and vert refresh rates of your monitors to put in there to replace mine. Remember, you also don't have to run xinerama, which is a spanning desktop where windows can be dragged accross, you can simply have two desktops whish the mouse can move freely between by turning the xinerama option off.

The XF86Config down there is built so that the bigger of the two monitors (I assume), will be hooked up to the GeForce and that it will appear to the left of the other.

Also, you may want to un-comment some of the modules I'm not using, yadyadya... add more font paths...

Cheers,

Finegan

i say xinerama sucks, and i have more than twice as many posts as finegan, which means i'm right... :D don't use it, it will probably cripple any video applications you use (my experience.. maybe i was unlucky)

finegan 08-16-2002 01:59 PM
I finally got mplayer to work after I switched to a Xinerama set-up, but chalk that up to quirkiness and possibly that it was also the first time I was trying mplayer out on XFree 4.2.0.

Kewp is the ninja though, even though he hides his actual yearning for some KDE lovin'

Thanx for all the help guys,

I installed Mandrake 8.2, and I really didn't like it at all, I much prefer RedHat. So this weekend I'll be installing RedHat 7.3 and hopefully your sugestions will transfer over fine

Sorry for the late reply, I've been very busy with work and havn't had much time to get online.

jpc82 08-23-2002 08:24 AM
Finegan I tried running XFree86 -configure, and this is what I get

and start again.

acid_kewpie 08-23-2002 09:00 AM
well.. IS a server already running????

jpc82 08-23-2002 09:12 AM
what server?, I don't know much about XFree86.
I'm in the GUI, is that the problem? If not which server?


If it is that I'm in the GUI, how do I shut it down?

acid_kewpie 08-23-2002 09:18 AM
yes, you can't have X running while trying to configure X.. it'ds not possible. if you login with an X login manager then as root run "init 3" and then exit X your normal way, or just kill X with ctrl+alt+backspace

Can i suggest you try to make better use of the error messages you get when something fails? they're there for a reason. thanks.

jpc82 08-26-2002 08:46 AM
Ok, I closed X and ran that file. It placed a XF86Config.new file in my root directory. So I looked at it and my XF86Config-4 in myX11 dir, and the one finegan posted and made what I thought was a good confige file, well it wasn't.

I renamed my old XF86Config-4 file to XF86Config-4.old and put the new one in its place, and rebooted. The system booted fine, but instead of getting the KDE login screen all I have is thedefualt screen that you get with init 3 on my main monitor blinking on and off.


This is my new XF86Config-4

Sure it isn't 75-121 and 46-76? With the monitor its only getting to try exactly one range combination.

jpc82 08-26-2002 11:58 AM
I figured out the problem, it was with the color depths. Once I changed that they work.

As for the rates that I put in, thats exactly what was in XF86Config.new, which is my new problem. I want it to run at 72 Vertical, but it will only run at 75 right now. Is there a way to probe the monitor to find out what rates I can put in there?

finegan 08-26-2002 12:14 PM
Well, you can check /var/log/XFReesomethingorother to see the modes it tried before settling on one, but really its best to just look up the specs of what your monitor is capable of.

Cheers,

Finegan

jpc82 08-26-2002 12:23 PM
I got this monitor used and free, so I won't be able to find out that info. I guess I'lljust have to live with it this way.

It seems so far that the problems I get in Windows when I have it at 75 or higher does not happen in linux, so it should be ok
