I built kernel and modules and installed them, but the experience is not exactly the same. (I am following this recipe <a href="https://01.org/linuxgraphics/documentation/build-guide-0">https://01.org/linuxgraphics/documentation/build-guide-0</a>) Re: GuC firmware loading as a workaround: my theory is that it is a race condition with modesetting happening during the time displays disconnect (taken from here <a href="https://patchwork.kernel.org/patch/8603521/">https://patchwork.kernel.org/patch/8603521/</a>). Anything can tip off race a condition, so I tried a number of i915 options, including firmware loading, it seems to be helping (hard to prove negative). One additional piece of data I failed to mention: my set up is to turn off laptop display when connecting two external monitors, and turn it back on when I disconnect them. Stanislav, laptop screen literally freezes - the image is still there, mouse moves, nothing happens on click or keyboard input. Two external monitors stay black.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
