XWindows Dual screen on a C610

July 23rd, 2004 by pete Leave a reply »

Again, more boring work stuff, but I need to keep it for posterity.

Getting Dual screen to work on a Latitude C610 was a bit of a bind, but I got there in the end after googling. I wanted to have both the internal LCD screen working, plus the external monitor functioning as an extension of the KDE desktop. Problem was, the XWindows config tool (sax2) in my distribution (SuSE 9.1) can’t handle a dual monitor setup with the ATI Mobility graphics card in the C610. In the end, I used sax2 to write first one setup (internal only), then the other and merged the output of the two files. Towards the end of the file, you’ll see I enabled Xinerama and specified my monitor layout. Voila!

Here’s the XF8Config file from a working system (Internal LCD screen and external Dell 1025HE monitor) with one desktop. (still can’t get GL screen savers working this way, but that’s the least of my worries.)

    It’s really boring stuff, isn’t it? :) This is what I do all day these days – fart around with config files that refuse to obey what I think are basic instructions.

    Ho hum, It’e becoming clear I made a wrong turn in life by making my hobby my career. Should have kept them seperate really. Bollocks.
