Update xorg to 1.18 - this issue should be fixed there, I think. Alternatively try plugging things into different ports. <div class="gmail_quote">On Feb 29, 2016 9:32 PM, "Peter Hewett" <<a href="mailto:nouveau@hewett.co.nz">nouveau@hewett.co.nz</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi My desktop is Kubuntu 15.10 with GeForce GTX 970 and two monitors, using the Nouveau drivers. In System Settings > Display and Monitor, the two monitors are shown but with the same identifier, DVI-0. This is giving some problems such as random allocation of primary screen and no right click on one of the monitors. How can I get the monitors to have different identifiers?
