After testing in bug 982889 I think we found I was never hitting the same bug there, so I will unduplicate this for now
** This bug is no longer a duplicate of bug 982889 X trying to start before plymouth has finished using the drm driver -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1125759 Title: Intel integrated graphics boots in low graphics mode Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After successfully installing 13.04 on my Dell XPS 15z, I restarted the laptop, successfully booting into Ubuntu with no issues. Restarting after that then gives the 'System is running in low graphics mode' message. I can only boot in recovery mode As mentioned in bug 982889 comment#5 "A workaround is to add some sleep to /etc/init/lightdm.conf: sleep 10 exec lightdm" This works around the issue. However, with further testing it was found that bug 982889 was not being bit and the fix does not fix this bug.
