Dual monitors. Ubuntu cant detect main monitor


Hi, My PC has a VGA port only, no DVI or HDMI ports. I installed a nvidia 290NVS dual graphics PCI card to enable me to have two monitors, and used windows to update the drivers. Windows detected both monitors immediately, but Ubuntu detects only the secondary 19" HP monitor. The main 22" TV monitor opens the grub menu but as soon as it starts booting into Ubuntu it loses the signal, and the screen turns blue. At this point the 19" HP 2nd monitor kicks in and boots the ubuntu OS system.

The original graphics were Intel G41 chipset. The bios records only the nvidia card as does the ubuntu system although the drivers quoted are nouveau.

I have been advised that it is a driver issue but I find this difficult to understand for the following reasons.

The drivers, graphics and screen work perfectly on the 19" HP monitor so why would I need different drivers just to have an additional monitor???

If I disconnect the power cable from the 19" HP 2nd monitor, the main TV 22" monitor still wont boot into Ubuntu although it worked perfectly prior to the nvidia installation.

I tried 8 other Linux distros, including Ubuntu 12.04, Ubuntu 12.10 lubuntu 12.04, Full Monty, Mint, Knoppix, Mageia, All these automatically detected both monitors.

I tried a newly burned ISO Ubuntu 13.04 cant detect main monitor
I tried Ubuntu 13.04 32 bit and 64 bit cant detect main monitor.

I would be happy to install Ubuntu 12.04LTS but it flickers slightly every 5/7 seconds which becomes irritating.perhaps it would be easier to sort this issue.

here is some details

maggie@margaret-VS273AA-ABU-CQ5226UK:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1366x768+0+0 (normal left inverted right x axis y axis) 410mm x 230mm
1366x768 59.8*+
1280x1024 60.0
1280x960 60.0
1024x768 60.0
800x600 60.3
640x480 60.0
720x400 70.1
maggie@margaret-VS273AA-ABU-CQ5226UK:~$

As you can see DVI-I-1 is disconnected. This is probably the problem, but as stated above there is no DVI port on my PC, thats the reason i bought the nvidia dual graphics card.
Please help. Thanks

Have you installed the proprietary NVIDIA drivers?

thank you for your reply. no proprietary drivers installed but I have now resolved the problem and both monitors are up and running. It was very simple so I will put it here as it may be of use to someone else.

sudo apt-get purge nvidia

sudo apt-get install nvidia-current.

took about 10 minutes to download and install, rebooted and hooray both monitors up and running. Thanks again for your offer of help.

Glad to hear it, that second command installed the proprietary drivers.
