Triple Monitor Mint 18.3 Cinnamon 3 XScreens Cinnamon in Fallback Mode

Post by Seti118 » Sun May 06, 2018 6:17 am

Hi, I've spent a couple of days trying to sort this through various means. Each time Cinnamon crashes. The Set up is 2 1080P Monitors and one Generic 1024x768 Flat panel on Mint 18, currently running 18.3, due to noticing that the nouveau driver worked for this after fixing another issue under a Live USB. However after install there is graphics lag and cursor issues, which when dealing with 3D Modelling and Printing isn't ideal. So I'm left going back to the Nvidia drivers and separate X Screens, this works under the MATE desktop, however, I'm so used to Cinnamon I find mate a bit clunky, also Dual Monitors are fine, it's the 3rd that is causing the problem, which I'm assuming is due to it being an old Flat panel and reading as a CRT on a second Nvidia card as well as issues with multiple XScreens under Cinnamon.

Things tried : Various Nvidia driver versions, Grub nomodeset, multiple different desktop environments, fresh re-install, I'm sure there's more, but each time gives the same results.

I hate to hear that you are having problems with this. I finished my dual monitor setup this past weekend. I have missed having it, I forgot how useful they are. Hopefully someone with more experience will be along to help you out. I got to say though- this thread needs some pictures of that setup! :mrgreen:

Cheers, Dual works fine, I had Cinnamon working on the Nouveau driver but there was so much lag and occasionally it'd lock up with nothing actually clickable, but the mouse moved without issue, I'm currently back down to two monitors on the Nvidia drivers, as frankly, I need to run without graphics lag. I've not had time to sort the 3rd again and I'm half tempted to check Ubuntu with Gnome3 to see what happens. From what I can see, Cinnamon segfaults with an xorg.conf file in place and multiple X Screens I just can't really win on this one.

Multiple GPU/multiple monitor support is still poor in Linux, when compared to Windows.

Your best option is to connect the 3 monitors to the same video card, using an adapter if needed, or getting a different third monitor.

Xorg’s Xinerama feature is supposed to work with two identical or similar video cards, to allow connecting monitors to two GPUs, but your two cards are not similar enough.

However, I just tested Xinerama using Cinnamon 18.3 and it would not work well, although my video cards are old. You can read my answer in my last post in this topic, which is related to yours: viewtopic.php?f=59&t=269743

The alternative to Xinerama is Nvidia’s Base Mosaic, which requires two identical video cards, but it did not work for me using Mint 18.3 Cinnamon, Xfce or MATE.
