I have my laptop duel-booted Windows 7/Ubuntu 14.10 running with the KDE desktop (although this problem was present before I changed from Gnome). This problem has been present ever since I first installed Linux. My computer supports resolutions up to 1366 x 768, but my Ubuntu states its maximum resolution as 1024 x 768. If anyone knows of a way to fix this, please help.

Result of running xrandr:

xrandr: Failed to get size of gamma for output default

Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768

default connected primary 1024x768+0+0 0mm x 0mm

   1024x768       0.0*

   800x600       61.0

Result of running lspci | grep VGA (for finding the graphics card)

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

Any help is much appreciated, and if any more information is required, please ask.

EDIT: I just tried running the Intel Linux graphics installer to see if my graphics cards needed updating (though they should have been up-to-date already). The graphics installer then said that my distribution was not supported. Does Intel support 14.10?

EDIT #2: I found that Intel has not released official drivers for Ubuntu 14.10 (I had thought originally that they had and that I had installed them). I am going to back up my computer and do a fresh install back to 14.04 to see if that fixes the problem.
