Yesterday i install Manjaro and a install optimus manager because my laptot have 2 graphics card. RTX 3060 and AMD GPU. But i cant change resolution for laptot screen . When i tried i got this window and is very wierd. The default resolutio for laptot screen is 2560 x 1440. But i wnat change too 1920 x 1080. If i start nvidia-settings tells me that is manged but PRIME Display and i cant do anything.
okay you’re on x11. keep in mind that wayland isn’t working with nvidia.
next is to switch to your nvidia-gpu. your actual setting is the igpu so called “sgi”. please post the output of
systemctl status optimus-manager
btw.: what gui are you using? plasma,gnome,xfce… ?
okay, please read the following in the link below that is addressed to gnome-users and do the required steps carefully
If you use Gnome or the Gnome Display Manager (GDM), there are a couple extra requirements to be able to use optimus-manager :
The default gdm package from the Archlinux and Manjaro repositories is not compatible with optimus-manager, so you must replace it with this patched version : gdm-prime (also replaces libgdm). The patch was written by Canonical for Ubuntu and simply adds two script entry points specifically for Prime switching. The package is otherwise identical to the official one.
Gnome launches Wayland sessions by default, which are incompatible with optimus-manager. To force Xorg sessions, You need to edit the file /etc/gdm/custom.conf and remove the # before the line #WaylandEnable=false.
check your system-settings. there should be the panel-setting where you can choose if the displays are merged to one or separated and separated to which position.
they are merged to one display actually.
edit: i can see at the left side the panel setting. there are the settings included, you’ll have to check out what you want.
the actual, same than yours. it’s not a question of the driver. you’ll have to check how to set up the displays in gnome. while i’m on kde i wouldn’t be a help for this. but there are so many tutorials for example at youtube.
