I don’t see it documented in https://www.spice-space.org/spice-user- manual.html#_multiple_monitor_support.Yep, it's a fairly new feature. I'm working on additional multi- monitor documentation and will be sure to include that.ThanksFor Christophe F, what I get with the configuration file http://p aste bin.com/FEXbjaE3 is shown in the following picture https://re dski ncat .wordpress.com/2017/02/27/learning-more-about-mesa/#jp- carousel- 1224. As far as I remember, this is pretty much a default configuration of Fedora 25 after install from the live CD. If I understand correctly, the difference with you is that I actually installed. Does anybody else see this? If not, what could be wrong with my setup?I don't see anything obviously wrong with the configuration. If you close the spice client and immediately re-connect does it still show the same thing in both windows?Yes. It reopens two windows, both with monitor 2.Can you capture the debug output of running virt-viewer with the -- debug and --spice-debug options while you enable the second monitor? That might give a clue about what's happening.Attached. I find it suspicious that we only have surface id 0.I didn't see an attachment. Maybe it was stripped because it was too big? Perhaps a pastebin somewhere would be easier?It’s here: http://pastebin.com/EY0AjfHK Thanks ChristopheSo, I did manage to reproduce this now. I just created a new guest vm and installed a fresh fedora25 and I finally observed the issue. I also observed that sometimes the screen would flash back and forth between the contents of screen 1 and the contents of screen 2. You can see a video of that here: https://youtu.be/aQhv9Q45ecM Yes, that's similar to what i experienced, it currently works for me with large enough memory (didn't help before the update), but I just noticed that if i apply 2 displays before login it doesn't work at all. I think gnome behavior has changed , applying 2 displays (logged in) causing to automatic log out, iirc it didn't happen before the update. The client is sending the appropriate config to the guest, but the guest is incorrectly configuring the two displays at the same position (0,0). The displays aren't actually mirrored, they're technically two separate displays but they're both located at the same position on the underlying surface. Pavel and Snir both mentioned on IRC that updating packages on fedora25 fixed the problem, but I found that even after updating everything on my new guest, I was still able to reproduce the issue. I guess it needs more investigation to figure out which component is at fault here.
