Installing Multi Montior and Multi GPU on Ubuntu 20.04 using proprietary NVIDIA drivers
Installing Multi Montior and Multi GPU on Ubuntu 20.04 using proprietary NVIDIA drivers
I've just moved from Windows to Ubuntu and am facing some issues with the proprietary NVIDIA driver. My setup includes six screens (actually seven) on two GTX 1070 graphics cards. The first GPU works fine, but the second one is being detected by X Server yet not showing anything. It's on and you can hover your mouse over it, but no desktop or window appears. Open-source drivers handle this, but I need to determine the right configuration for my top monitors. X Screen 0 is functional, but getting X Screen 1 to display content is the challenge. Please share more details if needed.
Consider using gnome's setting centre for display configuration. If this doesn't help, attempt lxrandr as an alternative GUI method. The term "disconnected" likely refers to unenabled displays, so check that setting. Let me know your experience.
Check if you're running Wayland or Xorg. If it's Xorg, make sure to use arandr. Since you're a dwm user, you likely don't need to worry about Wayland display configurations.
wayland functions as a protocol managed by the compositor, typically a window manager. Certain utilities exist but require the compositor to be compatible. For more information, check out this helpful guide: https://arewewaylandyet.com/
There seems to be an issue with Ubuntu not detecting the monitors linked to your second card. It functions with new drivers currently, but I need the proprietary drivers for gaming. It looks like xorg might be involved.
I'm reviewing the outputs section of arandr. It seems you can manage displays via the DP interface there, without needing to edit xorg.conf. To proceed, please share your Ubuntu version and the current kernel release.
iamroot@iamroot-Z390-AORUS-PRO:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.3 LTS Release: 20.04 Codename: focal The screens are present but I can't turn them on. I used Fedora before switching to Ubuntu and faced the same problem; this guide helped. https://ask.fedoraproject.org/t/fedora-3...u/13785/18 but it’s Wayland so it won’t apply here. This essentially means a fresh install of Ubuntu 20.04 with all updates installed.
