The problem: I can't completely activate dual-monitor support in X. I've gotten X to behave as though Xinerama were active (eg. KDE allows me to drag things off to the left of the screen and new windows often pop up there) but the 2nd monitor (see below) does not receive a signal.
My setup:
A crummy old computer.
Gfx cards:
* Dell i810e. No monitor attached.
* ATI Radeon 7000 64MB gfx card. It has a DVI out, a VGA out and an S-Video out. There is a 17" flat panel on the DVI, a 15" flat panel on the VGA and an ordinary NTSC TV connected to the S-Video through a composite <-> S-video adapter.
Right now it is running Slackware 11.0 with a custom 2.6.19 kernel and Xorg 6.9. I recently enabled agpgart and ATI-related options in the kernel and I installed the proprietary ATI drivers from http://ati.amd.com/support/drivers/l...n-prer200.html.
Here is my /etc/X11/xorg.conf. As you can see, I've already tried a few different configurations. None of them really work.
Here is my xorg.conf file. I have a dual screen setup, except I'm using 2 seperate vid cards. The concept is the same, but the device section is different.
Does that ATI driver install properly with your card? It appears that the oldest card that the ATI driver supports is a Radeon 8500. In this case, you will most likely have to use one of the drivers that accompanies X.
Sigh...I suspected as much ever since the fglrx driver started spouting messages about not being able to detect any cards. Oh well, so much for that.
But neither the ati nor radeon drivers seem to be working. The man page for the radeon driver (which came with Slackware) says that it can do multihead, and when I use a configuration like Stompy's (eg. using a BusID and Screen in the Device section) X creates a second screen that I seem to be able to use...but the monitor says it isn't getting a signal.
I know the physical connection to the monitor is fine, though, because I can use clone/twin view configurations (that seems to be what happens if I have any bad settings, actually). It should be noted, however, that the monitor itself says it's running at 1280x1024@60Hz, though KDE thinks it's running at 1024x768 @ -19,000Hz.
Once I finish installing slackware 11.0 I'll post my xorg.conf, I had dual monitors working fine in Ubuntu for the last month or so using fglrx drivers. But using stompy's xorg.conf example looks very similar to what I had. You just need to double up some of the entries.
I think there may be some issues with Radeon 7000/VE in general. I found lots of threads about people not being able to get dual head support with it and none of them have working answers. Maybe that particular model is too old to be supported?
Btw, Swampdog, I recently found out that fglrx definitely doesn't support the 7k. You were right.
Oh well. Perhaps I can dualhead using the card + onboard i810e?
I know what you mean. It's too bad that support for older cards is no longer a feature of the proprietary ATI drivers. From what I can remember, ATI has not supported cards older than the Radeon 8500 for quite some time now. I had a Radeon 7500 in one of my Slackware machines a few years back, and wanted to enable hardware support for this card using ATI's drivers, however this card was not supported. NVIDIA seemed to support its legacy line of cards a little longer than ATI, but they now as well only support from a certain age. I don't know offhand what the cutoff is for the NVIDIA drivers, but I know that I could not use the latest drivers for my GeForce 256.
