Can't get my two displays to work at the same time on nvidia, begging for help

Ask Fedora
1

Hi, it’s my first week on Fedora (42 KDE Plasma, Wayland) and I’d love some help.

I’ve got a simple setup with my Wacom display and my monitor, I connect one of those on the RTX 3060’s displayport (usind an HDMI to DisplayPort adapter), and the other one on the HDMI port.

Unfortunately I noticed that xrandr only detects one of those at the same time. If I disconnect my monitor and connect my tablet, the tablet works and the monitor doesn’t, and if I disconnect my tablet and connect my monitor, the monitor works… while the tablet’s display doesnt. Oh, and by the way, all of the wacom features work fine, except for the display.

I know it’ s not a wacom issue because it works normally after disconnecting the monitor, the problem seems to be that there’s something (namely nvidia drivers probably) are simply blocking detection of the second output.

I installed the nvidia drivers using the akmods thingy guide and they work GREAT, except for this little problem.

I tried going from wayland to x11 and there’s no difference.

I would LOVE some help as I really need my tablet to work… thanks in advance.

makes total sense, doesn’t it? You disconnected the monitor

same thing, only reversed :slight_smile:

If both displays are connected, which connection does not work? The display connected to the HDMI port or the one connected to the DP port via the probably passive DP to HDMI cable?
Does any of the displays work connected to this adapter cable?

Do you really need to use a DP to HDMI adapter? If the monitor has a DP port then consider using a DP cable instead.
