Dual monitor is not working on 3.6.11-4.fc16.i686.PAE?


$sudo lspci | grep -ir vga 00:02.0 VGA compatible controller: Intel Corporation Device 0162
However, the xrandr doesn't show the other monitor.
sudo xrandr Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 VGA1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 410mm x 230mm 1366x768 59.8*+ 1360x768 60.0

HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis)


I tried using the system utility; that threw an error saying Other monitor is not detected.

How can I get it detected and make it working? Please share your views.

Check what driver is being used. VESA will not work, I think, with xrandr.

BusID 1:00:0 is the video and 1:00:01 is the audio. so if what im thinking is right, It seems like the driver for your ATI video is not being loaded. Is the other monitor connected to ATI?

i915 is loaded for your intel card so that part is ok but no fglrx or radeon for the AMD card.

Hi,

Thanks! What I did today was;
http://support.amd.com/us/gpudownloa...eon_linux.aspx

From here, I downloaded the latest beta version.

Now, I rebooted. The first screen started showing me all the booting logs.
Before launching the login screen. I got the other screen active. The first screen just showed .. launching display manager.
And the other screen showed the login screen. I logged in and was able to use only second screen. When I pressed alt+f2 ; I was able to switch to first screen but this just showed me..launching display manager. I couldn't do anything.

My desire is to use dual monitor setup. Thus, I will be able to move my workspace items to another window.
Afterwards, I installed NVidia-config. This is also not helping me.

Nvidia??? I'm assuming this is typo coz you have AMD ATI and not NVidia.

So at least now you've seen both monitors turn on just not at the same time.

A few questions:
1.) are you using the intel card as well or both monitors on ATI card?
2.) do you have xorg.conf file?
3.) before we try number 2, try using xrandr again and see if it will show two displays now.

Edit your Section "ServerLayout" and add:
Screen "Screen1" RightOf "aticonfig-Screen[0]-0"

Also add these for you second card, monitor and screen:

Section "Device"
Identifier "Intel"
Driver "i915"
BusID "PCI:0:02:0
EndSection

Section "Monitor"
Identifier "Monitor1"
Option "DPMS" "true"
EndSection

Section "Screen"
Identifier "Screen1"
Device "Intel"
Monitor "Monitor1"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

Section "ServerFlags"
Option "Xinerama" "on" #This is so you can move windows from screen to screen
EndSection


And finally, on your first Section "Screen", add this under SubSection "Display":
Virtual 2560 1024 #This is if you have two 1280x1024 monitors.
