sorry, I posted the logs twice. I just want to mention that my above logs were collected when only 2 displays are attached (in which case, the graphics functions ok), despite that you can see plenty of pipe A FIFO underrun errors.
do you want me to connect the 3rd cable (to the TV) to trigger the crash, and recollect the logs? ** Attachment removed: "AlsaInfo.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1675204/+attachment/4842918/+files/AlsaInfo.txt ** Attachment removed: "BootDmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1675204/+attachment/4842919/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1675204 Title: Intel HD graphics crashes when connecting to 3 outputs (DVI+HDMI+DP) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1675204/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
