(Failure on our part to propagate the error and a failure to never try again.) If it is deterministic, that would be very useful for debugging. *** Bug 82236 has been marked as a duplicate of this bug. *** *** Bug 83873 has been marked as a duplicate of this bug. *** Hi Guo, Rotation is working fine on my bdw here with recent -nightly. Could you please verify if it is still happening on your side? (In reply to Rodrigo Vivi from comment #4) > Hi Guo, > > Rotation is working fine on my bdw here with recent -nightly.

Only "xrandr --output eDP1 --rotation normal" works well. Rotation left, rotation right and rotation inverted all unable to work.

xrandr --output eDP1 --rotation normal
I can reproduce the issue on the SNB and use the kernel on 3.18.0-rc1_drm-intel-testing_a08ea5. reproduce step: xrandr --output eDP2 --rotation inverted This bug also appear on BSW, when change rotation normal or inverted, have the chance to be blank screen.
kernel version: drm-intel-testing c3e107ab06274aa47f082df40ee4365e480e7b2a
test steps:
xrandr --output eDP1 --rotation normal
xrandr --output eDP1 --rotation inverted

This bug should only be about the link training error in the original report. The common failure is bug 86548. Please retest with current drm-intel-nightly and http://patchwork.freedesktop.org/patch/41360 I had reproduce this issue with nightly branch(2014-09-24), and it is unable to reproduce on latest nightly branch. Change state to verified. Closing verified+fixed. |
