    Intel Graphics. After 14.04 Upgrade Resolution Limited

    I originally posted this in the ubuntu hardware forum because I didn't realize this System76 forum existed. I have a Ratel Performance I bought last year and just upgraded to 14.04.

    I have a 30" Dell monitor connected through DVI to a System76 with Intel graphics (details below). After upgrading to 14.04 my resolution is now limited to 1920x1200, before I was running at 2560x1440 (or 2560x1600, I don't remeber).

    I read that 14.04 has the latest driver and the Intel driver installer says trusty isn't supported. I assume it is a driver/kernel issue, is that safe to say?

    Code:
     *-display
           description: VGA compatible controller
           product: Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller

    If you type xrandr into a terminal what does it give back ....... just after some more information to start with
    it may help others.

    xrandr

    as an example on my own machine it gives back the following .....

    Same problem and same output. My monitor supports up to 2560x1080 and with 14.04 is limited to 1920x1080
    With 13.10 works fine at 2560x1080

    Regards

    I tried with a newest Nvidia and the same results, the maximum resolution is 1920x1080. I test it with the privative Nvidia drivers.
    I'm going back to 13.10 where works fine with the correct resolution.

    Re: Intel Graphics. After 14.04 Upgrade Resolution Limited

    I experienced the same thing, and booting off the 13.10 kernel (ie, Linux Kernel version 3.11.0) at the GRUB prompt is a useful workaround. (ie, during system bootup press escape before the splash screen, and go to "Advanced Ubuntu Options" and select a 3.11.x kernel).

    This may be related to the new kernel's preference to boot with VESA support;

    excerpted /var/log/kern.log from 3.11.0 (high resolution output works on this kernel):

    The highlighted line is an obvious difference. It's possibly a bug that it doesn't succeed in replacing the vesafb with inteldrmfb during initialization, or this might be a total red herring. But booting off the old kernel definitely works around the issue.

    Thanks, I suspected it was kernel config related.

    Is there a better way to bring this to System76's attention at least? They must be shipping a working setup with these now on 14.04.

    If you go into your orders within System76, you can file a support request against the order. However, most of the time they tell you to log faults like this upstream.

    I filed a bug upstream with Ubuntu here:
