How do I configure dual monitors with ATI 4870 on Slackware 14?


How do I configure dual monitors with ATI 4870 on Slackware 14?

I read several sources but most are old and contradicting. Once source said to make a xorg.conf file in /etc/X11/ another source said to make one in /etc/X11/xorg.conf.d/ Another said not to make any conf file since that is old.

I'm using the open-source driver for ATI 4870 and am running 64-bit Slackware 14. The current configuration has my second monitor as a clone of the first monitor. This is on my desktop with both monitors having resolution's of 1920x1200.

Please help,
Thanks

You can use either an /etc/X11/xorg.conf file or a config file under /etc/X11/xorg.conf.d/

In those cases, take a look at the xrandr wikis:

http://www.thinkwiki.org/wiki/Xorg_RandR_1.2
http://wiki.debian.org/XStrikeForce/HowToRandR12

You can also choose not to use either and use the screen display utility that comes with your desktop environment (assuming you are using a DE that comes with such a utility).

You can also simply create a script that calls xrandr with the necessary commands and add that script to your X session.

It's finally working !!!

It's finally working!!! I tried to edit my xorg.conf file but that didn't work. So I just used KDE's Screen Resize & Rotate(KRandRTray) and everything works.

An issue I have is that I have two DVI connections on my video card and it correctly label's the first connection as DVI-0 but the second connection is labeled HDMI-0 when it should be DVI-1. Is this some sort of bug or am I missing something? Another issue I have is that I don't know where my actual configuration file is or what it's named. I also don't like to use graphical tools, is there a way to do this by command line?
