[drm:intel_dp_start_link_train], too many voltage retries, give up

Question

Upon startup in Ubuntu 14.04 on my Asus Ux32vd laptop, I get the following error:

"[drm:intel_dp_start_link_train], too many voltage retries, give up"

The computer boots fine otherwise, but I don't know what the issue is.

Answer 1

I have UX32VD laptop and found same problem. This realy comming up when switched to Nvidia. Same freezes to me, so I do like ber4444 said Ctrl+Alt+F1 then Ctrl+Alt+F7 then Alt+Tab. Related bug seems to be fixed https://bugzilla.kernel.org/show_bug.cgi?id=74931 already by patch.

Answer 2

I see these occasionally on my Dell XPS 15 (L322X) it doesn't seem to hurt anything and I can't pinpoint a specific cause for it.

I doubt it's anything to worry about.

Answer 3

FWIW. I used to get "drm:intel_* give up" messages coinciding with actual and frequent screen blanking, i.e. monitor goes black for a few seconds, comes back, blanks again...

My solution was to replace my Display-port (DP) cable+adapter with a good quality DP cable with latching (about $10 online). A good DP cable locks into the socket and maintains good electric connections between the graphics chip and the monitor.

Update: since replacing the cable a few months back, I haven't experienced any screen blanking nor any drm:intel_* errors.

The monitor cable replacement fix has proved to be a complete success.
