Re: [PLUG] Matrox G400 AGP dual head

Well, the ATI ...

(01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE))

... automated software is nice (I thought), though when I tried to get the second monitor working again (A TV using the computer's video output) my machine kept hanging up and I had to reboot several times.

I did have it working just the other day, both in "independent" monitor mode and "left of" and "right of". Though now I cannot seem to get it to work again after trying 4 times. I recall having some problems when I tried before, so it is sort of buggy I guess, and I got lucky with the order in which I did things.

Yup, ATI and NVidia both seem to work out of the box  (with proprietary) . The video card I have is a Matrox Millenium, kinda ancient, Matrox has some linux (binary) drivers which do not work. Based on my experiments so far, I need to set this up with xinerama, however have not had much luck so far. Thinking about going down to microcentre and getting myself a NVidia DVI (dual link) card. Any suggestions?

Thanks

This is probably common knowledge but just in case....  I have an ATI graphics card, and when I loaded the Linux driver software from ATI it took care of everything, including a GUI and command line interface to toggle and configure dual monitors.   It even configured into my KDE desktop menus for me.

Maybe some other vendors do the same thing?  You did not mention if you had tried that or not.

Hello,

  I have been struggling to set up my dual monitor machine for a couple of days and thought that someone here might be able to help. Any help is much appreciated.

I am using a Matrox Millenium G450 dual-head video card

(AGP) with Ubuntu 8.10. I would like to be able to stretch my desktop across both

screens. At this time I have two copies of the same desktop on both screens.
