I think I have dual head but i want Big Desktop
Hello all!
I've just got this 17" CRT to test out with my slack11 box. After messing around with xorg.conf I "think" i have Dual Head but what I want is Big Destop. Why do I think I have Dual Head? From ati's knowledge base: Quote:
What I wanted was Quote:
Code:
Section "ServerLayout" Code:
# fglrxinfo Can I have one desktop expanded over two screens with 3D acceleration? If so how? Is Dual Head better than Big Desktop? Should I be better with Dual Head? Thanks in advance. |
I'll try and give you some info here to help you figure out what it is you want to do.
NOTE: I use an nVidia dual-head card, so the terminology I use is based on my setup, but the end results should be comparable. How you arrive at them may be somewhat different using your ATI card. Dual Head - generally refers to a card with two outputs. ATI may be using this term differently to describe what I know as two separate X sessions. Big Desktop - I haven't ever heard of this term, so I guess it's an ATI expression. By your description, it sounds like you want a 'panoramic' view, which on my system I achieve by using Xinerama. my Nvidia driver allows GLX and 3D acceleration and a few other things, while using Xinerama with two displays. ATI systems probably do as well, but I can't give you specifics because I haven't used an ATI card. nVidia also takes care of DRI internally, whereas with ATI you may have to enable it on your own. Big Desktop (copied from above): * A single desktop is stretched across both monitors * Monitors may overlap by a configurable number of pixels * Both monitors have to operate with the same video mode settings * Both screens use a single framebuffer and only one window manager o The smaller display will NOT autoscroll as in Clone Mode * Big Desktop can be configured for Horizontal or Vertical operation Xinerama (the way I have mine set up, for comparison): * A sngle desktop can be stretched across both monitors, including OR excluding the taskbar. OR, each desktop can be unique. * The stretched method shares a wallpaper; the separate unique desktop method gets two wallpapers. * Monitors may overlap by a configurable number of pixels (but why would one want this?) * Both monitors operate at the same color depth, but may have different resolutions. * Both screens use <framebuffer(s) unknown> and only one window manager. * Each desktop scrolls, maximizes, minimizes EITHER indepentently, or together, whichever you want. * Horizontal OR Vertical configuration operation, whichever you want. * Windows can be dragged from one screen to the other, and mouse goes from one to the other too. Your file is very similar to mine, except for in yours: Xinerama being off.. The 'RightOf' option (I use absolute x and y locations).. And I have a couple nVidia-specific settings. Not sure all this helps you any, but I do hope it helps you figure out just what it is you would like to do with your desktop. :) |
Hello GrapefruiTgirl, thanks for your reply.

Hi there :)
My xorg.conf is on LQ here somewhere, in a thread called "Four screens with one CPU" or something similar. Just search my posts and you will find it. If you can't, then I will post it again :) |
!FIXED!
Thanks but there is no need for it, I managed to get it to work. After reading some ubuntu how to about this I've tried this: Code:
aticonfig --initial=dual-head -dtop=horizontal --screen-layout=right Here is my new xorg.conf Code:
Section "ServerLayout" |
From a post on ubuntuforums:
Code:
Option "DesktopSetup" "horizontal" #Enable Big Desktop |
