I confirmed the same resolution can be obtained when booting Xubuntu 13.10 from USB. I recently upgraded to Xubuntu 14.04.1 and now the external display will not run at anything higher than 1920x1200. xrandr does not show anything higher than that available. Confirmed the same issue exists in Mint 17 XFCE when booting from USB. Note I am not sure if the kernel is in fact the issue, but such was suggested on this thread where I found what appears to be the same issue here: http://ubuntuforums.org/showthread.php?t=2218618 ... though without a resolution, and I am not a system76 customer. xrandr output: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected (normal left inverted right x axis y axis) 1440x900 60.0 + 59.9 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 60.0 1920x1080 60.0* 50.0 59.9 1600x1200 60.0 1680x1050 59.9 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.9 1152x864 75.0 1280x720 60.0 50.0 59.9 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 720x480 60.0 59.9 640x480 75.0 72.8 66.7 60.0 59.9 720x400 70.1 DP2 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8 ProcVersionSignature: Ubuntu 3.13.0-32.57-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 CurrentDesktop: XFCE Date: Wed Nov 12 12:46:52 2014 InstallationDate: Installed on 2014-11-09 (3 days ago) InstallationMedia: Xubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140723) SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: XFCE DistUpgraded: Fresh install DistroCodename: trusty DistroRelease: Ubuntu 14.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a26] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Apple Inc.
