If I boot normally, or go through the firmware UI (hold down volume *up* key when booting): * Early boot, all the way from Dell logo to the point where KMS tries to kick in, looks to be in native resolution (800x1280) * KMS fails as described in this bug, screen blanks when it kicks in But! If I boot through the boot device menu (hold down volume *down* key when booting): * Early boot is in some other resolution - lower, and not the right ratio, text is squashed * KMS works! When it kicks in, the display switches to native resolution (800x1280) and I get a successful boot, all the way into a fully accelerated GNOME session So not sure if that helps anyone figure out what the bug is, but hey, at least it's a workaround for me for now. I'll attach updated drm.debug logs from 3.18 soon.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
