Unable to save settings for 4 monitors in X windows - Nvidia

bandroidx · 2015-11-25 08:11:29

Hi, I recently added a 3rd and 4th monitor to my arch linux box and am having issues saving the x windows configuration from the nvidia x server settings applet. It tells me that my metamodes list is too long. I did some googling and it was recommdned I run sudo nvidia-xconfig which does save a new xorg.conf without issue, however, it only includes metamodes settings for 3 of the 4 monitors. Anyone can suggest a way to solve this issue with 4 monitors in my xconfig? Thanks

Are you using "Base Mosaic" setup ?

If so, that's limited to 3 monitors UNLESS you have Quadro videocards.
(it's an artificial limitation imposed by Nvidia for their linux driver)

No, I am not, I just checked advanced and saw that is not checked.

I am using a 660ti, not a quattro card, it does work with 4 monitors its just that i cant save a config so that its enabled when I reboot. Right now I am using 4 monitors just fine.

This is what happens when I try to save the x config from the nvidia applet and tell it not to truncate the meta modes: http://i.imgur.com/zO2wsyt.png

This shows how the monitors are actually configured(layout): http://i.imgur.com/SmzzHk7.png

I am guessing the fact the 4th monitor is positioned above the middle monitor is what is confusing the metamodes generation so badly perhaps?
