HP Compaq 8000 E7500 displayport shows timeout errors in log, and doesn't come
up at all. Monitor is IBM ThinkVision, connected with straight cable. VGA
works.
Default Ubuntu kernel and DRM-Tip show same symptoms: monitor shortly coming
out of power save, then going back and no picture.
BIOS screen shows up through DP well enough.
DRM-Tip dmesg with drm.debug=0xe attached.
