Which probably means there's a broken component somewhere in the signal path. Could be the level shifters in the source, cable, dongle, or the monitor itself. The workaround I've been suggesting is to add a knob for the user to limit the color depth. The problem for cases like this where there is no output (as opposed to just glitchy output) is that a connector property would have to be changed by the user blind. The alternatives would be to change the default to 8bpc, or add a modparam (or something like it) to force the 8bpc already when the driver loads. Hmm. Maybe we should extend the "awesome" video= cmdline syntax a bit?</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>
