Hi Frank,<div><br></div><div>My testing has been nearly all with multiseat, so I'm ignorant of many of the Xinerama and Xrandr ins and outs of getting extended desktop working. So I may get this wrong, but some of the potential causes:</div>
<div><br></div><div>* Because xorg doesn't have multiadapter support yet -- without Xinerama on, the displaylink and intel drivers can't coexist in the same layout, which may be the cause of the unload. Anyone know another way in which they could?</div>
<div>* The current displaylink framebuffer driver is 16bpp (and may want to stay that way for performance/simplicity reasons). Xinerama requires all screens to be at the same color depth.</div><div>* Probably don't want to have a SubSection "display" today for any displaylink device if you're using the monitor's preferred mode, as displaylink-mod gets the best timings from EDID, there are no Depth options, and 24bpp may cause a problem (seemed like removing that solved a problem recently - mentioned on this list)</div>
<div><br></div><div>I'd try setting the Intel/TV to 16bpp and turn Xinerama on, and see if that works.</div><div><br></div><div>Again, I'm ignorant of a bunch of things, so I may be missing a better way. If anyone has a suggestion, hopefully they'll hop in. And it'd be great if you can report back if you're able to get it working.</div>
