Unfortunately, there is also an issue with the graphics driver in the UEFI firmware, that it often is not able to initialize the display. So Linux’ UEFI frame buffer driver doesn’t display anything. So, let’s make the bug about the issue, that the Linux kernel (not user space) Intel graphics driver i915 is not able to initialize the display when loaded. I jumped through the hoops to build latest drm-tip. Please find the log with `drm.debug=0x1e` attached. Hopefully, the logs are useful, so that we do not have to guess, what’s going wrong.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
