Time Event
Problems with dual-display in Fedora 7
I was given a second LCD monitor this week so I bought a Sapphire ATI Radeon HD 2600 Pro (AGP) card, thinking it wouldn't be so painful to get it working.

I know it can feed both screens because (more by accident than design) I've seen output on both ... just not in the way I want to, but at least I know there's not a hardware problem.

My problem is that I can't get it to work how I want, which is to have one screen (the left one) as the primary screen and the second as either a separate or extended desktop - I'll settle for either now.

That website only has drivers for Windows XP and Vista, so I found the unofficial ATI Linux Driver Wiki - Fedora 7 installation guide, which led me to the official ATI Proprietary Linux Driver page, which in turn led me to a page where I could download Catalyst, which I did.

I tried running Catalyst and selected "Install Driver 8.471 on X.Org 7.1 and later releases" which, although it didn't report any problems, didn't work properly - it gave me an error along the lines of "No ATI graphics driver is installed, or the ATI driver is not functioning properly."

OK, so then I found a promising page entitled How to Install Video Drivers on Fedora 7. I skipped the nVidia section and went straight to "How to install ATI drivers". (I did download their version of the installer but it was older than the one I already had (from the ATI/AMD site) so I stuck with the first one.)

Building the drivers seems to have me stuck in a loop (me, not the machine!) because of the dependencies. I'm currently running with kernel-; kernel-headers and kernel-devel match that version number.

I installed kernel-module-ATI-fglrx-, ATI-fglrx-8.471-1.f7.i386.rpm and ATI-fglrx-control-center-8.471-1.f7.i386.rpm but ATI-fglrx-devel-8.471-1.f7.i386.rpm gave an error: Failed dependencies: /usr/include/GL is needed by ATI-fglrx-devel-8.471-1.f7.i386

Checking what needed to be installed to fix that dependency (yum whatprovides /usr/include/GL) returned 2 packages, but when I tried to install them (yum install xorg-x11-drv-fglrx-devel.i386 xorg-x11-proto-devel.i386) I was told Error: conflicts with ATI-fglrx ... but that's what I installed (from Catalyst) just a minute ago! Now I'm stumped.

I ran yum clean all ; yum update just to make sure everything was up to date (which I do most weekends) and it was. Oh, for completeness, the repositories I use are Adobe (http://linuxdownload.adobe.com/linux/i386/), Fedora (http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-$releasever&arch=$basearch), Updates (http://mirrors.fedoraproject.org/mirrorlist?repo=updates-released-f$releasever&arch=$basearch), Livna (http://rpm.livna.org/fedora/$releasever/$basearch/) and Macromedia (http://macromedia.rediris.es/rpm/).

So, I guess my questions are has anyone got this card working with Fedora, and/or any suggestions as to how to move forward?
