I have just installed Kubuntu on ASUS U46E BAL7. The installation went fine and I am able to use the desktop. But it seems to recognize only one monitor at a time, either the laptop or the secondary one and not both. Besides this the resolution being shown is far less than the capability of either monitors.



I was able to generate a xorg.conf file, but that seems to be mostly empty. I am skeptical about editing it and screwing up what's working now. Is there a way to dump existing configuration that kubuntu is using into a file, so I can work by modifying those settings as opposed to writing everything by hand ?



Please find my xorg.conf file attached below.



Thanks million in advance.

Thanks

EDIT: Moved a bunch of data from an answer section non-answer into the question:



Thanks for the reply. I have spent significant amount of time trying to install ubuntu on this new piece of hardware. None of the 11.10 64bit versions boot up for some reason. So I went ahead and installed Server first and installed KDE after the server installation was complete. Besides the

sudo apt-get install kubuntu-desktop
I have not done much. I wonder if I missed any installations that are needed and this might be causing the problem. Your thoughts ....



EDIT



Apologies. Trouble with this output is I personally cannot understand it as it doesn't have any version info. So, I assumed output of lshw would have more info.



Output of lspci | grep VGA



00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)



EDIT



xrandr output:




xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 1024, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
1280x1024 77.0*



EDIT



Yes, I have the external monitor hooked up. If I have it hooked up during start it defaults to the external one and shows only that. It not, it defaults to laptop screen and shows only that.

This the error startx gives me.

Upgrading to Kubuntu 12.04 LTS with noapic enabled and nolapic and nomodeset removed solved this issue, if anybody is looking for it. If you have upgraded to 12.04 and not removed nolapic and nomodeset, it will not solve the issue. I am now able to view dual monitors at their highest resolution. Please let me know if anybody is unable to see this behaviour, I will report it on the bug or better yet report it yourself.
