It shouldn't, but what do we know, really? It's a black box. From the logs: [ 18.196168] [drm:drm_add_edid_modes.part.30 [drm]] ELD monitor BOBCAT2800 i.e. the "display" claims its name is BOBCAT2800 which I believe is the LSPCON codename. My educated guess is that the LSPCON has some sort of test mode where it fakes a connected display when one is in fact not connected. And that mode is enabled on the machines in question. Already <a href="show_bug.cgi?id=104257#c0">comment #0</a> alludes to this by saying that with HDMI display connected (to the LSPCON) there are no issues.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
