Right, I will just configure it in this way.įor the link you just send I tried things out, but it does not seem to work for me. Question to that: Is it planed for the PRIME functionality to support both graphics cards RAM in the future on Linux in some way?Īlright, thank you for your answer, lets see how things turn out. Otherwise I also have to think about upgrading to 12GB+ graphics… But at least its not too much yet with my 4x2560x1440 + 2/3x1920x1200 setup. I hope at least some applications like blender are able to use the other graphic cards RAM to avoid too much usage of the first one. When it comes to graphic RAM used I will see how it turns out. sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/ When setting up everything with the included GUI tool only, you just need to run the command after it. After that, you have to save the config on global level with the following command. ![]() I did this, by moving one display, saving, and moving it back. Too avoid that make sure to open the display configuration with the included gnome GUI display configuration tool and try to enforce saving display configuration again. ![]() When setting everything up with xrandr, you will notice that things get lost on reboot. When using GDM, the last command ( run xrandr -setprovideroutputsource NVIDIA-G0 NVIDIA-0 & xrandr -auto) is not even needed, as it will automatically detect what is there (at least when you do a full reboot, what I did). Thank you very much generix! That actually does the Job great. Is there some way to make it work with Base Mosaic on this specific hardware? Since I already wasted a lot of time with this topic, I wonder if there is some limitation that wont let me pass on this. I did not tried this with the seventh monitor attached, but the sixth monitor will already automatically be turned off at this point.Īs extra from all that I also tried when downgrading the driver to use legacy SLI/MultiGPU modes as described in docs, but that came out to only work with one monitor at all and not really well. MetaMode 1 of Screen 0 has more than 5 active display devices.With use of Base Mosaic (tried with driver 470, 495, 460, 450, 390) I was finally able to use more than 3 monitors with one X screen, but it was only able to let me activate 5 monitors with the error: It was not working at all and always ended in an black screen with mouse pointer on it. Otherwise I tried using Xinerama, with came out as disaster with everything I tied. But at least all screens get initialized with an unused X screen session. So far, I tried some different possibilities, starting with a second screen configuration next to the main screen configuration, which does not really work great on GDM at all. The second card powering the upper row of monitors powering the seventh monitor (attached by HDMI) that will get mirrored with one of the displayport connected monitors. Since this is a dual boot, the same hardware setup is running without any problems on Windows 10 with SLI activated in 6 and 7 monitor mode (seventh monitor is not always connected).įrom hardware perspective, both cards having all three displayport in use. I am using two GTX980TI (Windforce) with an SLI cable and already tied a few different scenarios (all configured by nvidia-xconfig). I’m trying to make a setup with in total 7 monitors (one monitor gets mirrored with the sixth monitor) run on my machine with Ubuntu 20.04 on it.
