I recently bought new laptop with two graphics cards: intel 4600 and Geforce 765M. Having seen this topic (How well do laptops with Nvidia Optimus work?) I abandoned any hope of getting the nvidia chip getting hold of my external display. However, I'm facing another problem, far bigger for me: the haswell chip does not recognize all resolutions my display has to offer (It's a Eizo S2402W connected via the VGA port). It stops at 1600x1200 and I need a native resolution of 1920x1200.

Things I tried so far:

  1. Installed a new kernel - 3.10 from kernel.ubuntu.com - no change
  2. Tried to insert new mode with xrandr - to no avail

My system is: i7-4700mq/8gb/gtx765m/intel4600 ubuntu 13.04 x86_64 with both stock kernel and 3.10 for saucy I also installed the nvidia-319 driver for testing of bumblebee

How could I set the native resolution of 1920x1200 when the xrandr does not allow that?

UPDATE:

In /var/log/Xorg.0.log the correct Modeline is present, but it is not available in xrandr:

UPDATE 2:

I checked my monitor with computer from work which runs Core i5-2410M with Intel HD Graphics 3000 on board, everything works fine. Version of Ubuntu is 12.04 x86_64 with stock kernel 3.2.0-51.

So taking into consideration that the intel chip (both of the actually) is aware of the resolutions my display reports (EDID):

UPDATE 3:

I updated the xorg griver: xserver-xorg-video-intel to version 2:2.21.14+git20130806.6004870d-0ubuntu0sarvatt~raring with no success.

UPDATE 4:

Just bought DVI2HDMI cable and bam, full HD resolution now works fine.

Correct me if I am wrong, but isn't this a limitation of the interface you are using (VGA)? –  Leinardo Smith Aug 8 '13 at 21:55
    
No, it is not a limitation of the interface. I worked on this display using different computer (much older one) and it worked fine with max resolution. –  racic Aug 9 '13 at 6:41
    
Have you installed any available proprietary drivers? –  Leinardo Smith Aug 9 '13 at 16:49
    
When I launch jockey (the app responsible for available proprietary drivers) it does not detect anything. It's not a problem though because I need to have Intel GPU working which runs a open source i915 driver. –  racic Aug 9 '13 at 18:01
