For the record, I tried out the intel driver from the elderberry ppa using the older kernel (the one from natty beta2) and it did not fix the problem. I still got:
[ 63.990093] [drm:ironlake_crtc_disable] *ERROR* failed to disable transcoder [ 164.540158] [drm:intel_dp_complete_link_train] *ERROR* failed to train DP, aborting [ 164.950081] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up [ 164.952644] [drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up The xset trick didn't have any affect either. So only the newer kernel resolves the issue. And I'm so happy about that :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762855 Title: [sandybridge-m-gt2+] Display on external monitor (vga) is black on 13" MacBook Pro 8,1 (x86_64) -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
