I got it! I’ve been working with two screens on Windows during many years, and when I completely moved to Linux I wasn’t able to get it working again, even if Fedora Linux has dual head support.
A couple of years ago, I had written about using two monitors with one PC, and the article is still receiving many hits. Many people are looking the way to do this. I decided to give it another try yesterday and got it right this time.
Working with just one screen, when you’ve been using two during a long time, is almost unbearable. My ATI x700 graphics card didn’t worked with Fedora Core 4 dual head. I later discovered the problem was me, I haven’t looked in the right places.
This is a problem with most recent ATI cards, which use their own drivers, not included in Fedora.
I started making changes in /etc/X11/xorg.conf, backing up the current copy first, and using the control panel provided by ATI’s driver, but I couldn’t see if it was working because X died, my screens were getting blank, and I couldn’t see what was happening when restarting X.
My solution?
In the computer with the two screens I opened a terminal window, as root, made my change for dual head in ATI control panel, clicked apply, and run init 3 to restart in text based mode.
Then I used my other computer, also running Fedora (but it could have been using any operating system, I just needed SSH access) and SSHed, as root again, to the one with two screens, and run init 5 to restart X. Halleluyah! It worked, but the images were in the wrong side.
I played a little more with ATI’s control panel, repeated the init 3 and init 5 steps above and got it right. Although, I could have just changed cables.
Now my desktop is looking great!
I can continue writing the spanish version of my book about telecommuting, with my word processor in one screen while I have reference material in the other.
If you are going to work with two screens, you better get some of these spectacular screen savers. Enjoy.
