Tested on Dell Venue 11 Pro tablet (Haswell i5 4210Y, Intel HD4200).
Tested this with the following distros, all with various versions of Xorg and
Linux Kernel.
Ubuntu 14.04 (daily iso build, up to latest)
Ubuntu 13.04
Ubuntu 12.04.3
Fedora 20 daily build
Debian Wheezy
Arch Linux daily build
With "nomodeset", I get varying levels of success when booting from legacy
mode. when booting with UEFI, I've had no such luck.
The only common error I've found across many of the distros is the following
error:
[drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting
[drm:intel_dp_start_link_train], too many full retries, give up
