Title: Dual Monitors as one big screen display
Post by: mguru on August 15, 2011, 08:48:59 AM

I have TCL installed on USB that is working well for a single monitor display. When I tried on dual monitor display, ( I have ATI card that supports dual monitors),after I downloaded xorg extension, booted TCL. I get duplicate screen display one on each monitor ( when I do ps -ef|grep Xorg, following process is what I see "/usr/local/bin/Xorg -nolisten tcp").

 I want these monitors to be one big screen display . How do I go about ? I tried xorg.conf file with couple of settings, and tried startx, the screen blinks and goes back to command prompt. I would appreciate if anyone has already tried it successfully, and can share config files.

I even copied xorg.conf.xvesa file for a single monitor , it does not display anything, the screen blinks and goes back to command prompt ( tc@box$ ).

Thanks

There are two solutions:
1.a proprietary driver ati_fglrx(aticonfig --xinerama=on)
2.randr extension of xorg

Thanks.  I have VGA compatible, ATI (Radeon HD5450), card that has a splitter to connect to 2 monitors. My xrandr -q output shows

Screen 0: minimum ......
1280X1024 0.0* <---- I guess this means active
all lower resolutions ...here..

I was expecting  somewhere in the output it would show  VGA/DVI/LV.. or something like DVI-0 and DVI-1 so that I could mention rightof / leftof to xrandr.

Assuming that 1280X1024 is my resolution per monitor, what would be my
xrandr - arguments for my situation ?
