I have been trying to resolve this for sometime.
I have an alienware m15 laptop with intel/rtx 2060 and connected to the alieware graphics amplifier with a gtx 1060 card tied to 2 external samsung 24" monitors.
I have this working completely fine in win10 and had it working in ubuntu 18.04 using nvidia390 drivers, but it only saw the gtx 1060 and not the rtx 2060, and running 4.15 kernel, but was needing to upgrade to 5.2.2 kernel to get wifi working, so installed nvidia430 drivers by way of “sudo ubuntu-drivers autoinstall” and now ubuntu sees both the rtx 2060 and gtx 1060 cards in nvidia-settings and it does see the 2 external monitors however, they will not turn on.
I can even go into gnome-control-center and it sees the monitors as disabled and trying to enable them does nothing. I ran xrandr -q and it reports all 3 displays, the laptop and 2 monitors, but the 2 monitors are disabled according to xrandr. I got the login loop and changed to lightdm and now I get the error popup “Could not set the configuration for CRTC 64” which from what I can tell online is either a bug in ubuntu or an issue with being able to change the resolutions, which I have tried numerous ways, the monitors refuse to turn on.
I am at a loss of what to try next. I am open to any suggestions…
Thanks in advance!!
