Comment 21 for bug 1138700

It is hard for me to believe that this bug won't be fixed for 12.04 / Precise. Can anyone tell me a workaround that I could apply? It is a real pain working with a machine that switches to text mode more than once a minute and displays the message

[drm:intel_dp_set_link_train] *ERROR* Timed out waiting for DP idle patterns
[drm:i915_write32] *ERROR* Unknown unclaimed register before writing to 64040,

When this happens, I have to press the Alt key in order to return to the graphic display. Please help me. Thanks in advance!
