I need some help/advice.
My setup is:
Manjaro 21.1.0
DE - KDE
Kernel - 5.13.11-1
CPU - Ryzen 5 3600
GPU - GTX 1660 (full size desktop gpu)
Monitor - 2x Dell S2721DGF 165Hz 1440p G-Sync compatible
Two monitors connected with Displayport to discrete GPU
So I decided to install Manjaro but with KDE and Gnome variant I got the same issue.
When I boot from the install USB and select load with propriety drivers I only got one monitor actively displaying content. Same with open-source drivers.
Now I install Manjaro anyway and after booting up its still the same.
I can change to 165Hz and G-Sync enable under nVidia settings panel and all 2 monitors are detected, set to extend. Even with all this one is black and shows nothing.
Virtually it seems to be working as I can bring an active app window to the black monitor.
I tried the official manjaro wiki about installing and checking nvidia drivers with no luck. Driver is installed.
Also the settings changed on KDE display or nvidia settings are not persistent and after reboot they reset.
Is this possible to fix or not much with my current nvidia gpu?
would enabling Xinerama in the nvidia-settings help? for multi monitor support
EDIT: forget this as it is spanning a single āscreenā over multiple displays which I donāt need
Do you have the 390 driver available in Manjaro Settings ā Hardware?
If yes, then right click the video-nvidia driver, then uninstall it, and after it successfully finishes, right click the video-nvidia-390 driver and click install (and reboot of course).
It is just for a test (as you just installed it is not really a problem if you break the system while troubleshooting, just reinstall in the worst case) to see if the issue may be with the 470 drivers provided by video-nvidia (but the 390 driver is really old and not optimal for gaming or resources heavy tasks).
Also Iām not familiar with GNOME, if you have time can you try if you have the same issue with KDE version? I know GNOME has some Wayland features enabled by default recently, maybe it is related?
what I noticed is that after applying the changes (which is DP0 monitor 2560x1440 , 165Hz , to the Left of DP2 monitor | DP2 monitor 2560x1440 , 165Hz , Absolute position (this is my main monitor)) it just blinks and goes back to some other setting like it reverted itself but the nvidia-config window still says the config mentioned above in the columns.
So it might not be able to apply the config?
also here is my .xinitrc file:
#!/bin/bash
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)
userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap
DEFAULT_SESSION=startplasma-x11
# merge in defaults and keymaps
if [ -f $sysresources ]; then
xrdb -merge $sysresources
fi
if [ -f $sysmodmap ]; then
xmodmap $sysmodmap
fi
if [ -f "$userresources" ]; then
xrdb -merge "$userresources"
fi
if [ -f "$usermodmap" ]; then
xmodmap "$usermodmap"
fi
# start some nice programs
if [ -d /etc/X11/xinit/xinitrc.d ] ; then
for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
[ -x "$f" ] && . "$f"
done
unset f
fi

Please make sure next time you properly format the text when posting it on the forum. .nvidia-settings-rc should belong to you as user, not root (just mentioning it)
Some good news.
I changed ownership on the file: chown -R t1v1wards:t1v1wards ~/.nvidia-settings-rc
ls -ld ~/.nvidia-settings-rc
-rw-rār-- 1 t1v1wards t1v1wards 2589 aug 20 13.04 /home/t1v1wards/.nvidia-settings-rc
Now its owned by my user.
I was able to run nvidia-settings with sudo and check/change the correct settings. Once applied it is now saved (I think there was a popup asking me to confirm the settings on the black monitor so I blindly pressed Tab and Enter until it worked).
After reboot changes are saved and looking great although the main problem is still present and my second monitor is just a black screen still.
Here are some screenshots of the settings after reboot.
of or off or on ?
if is off then it will be black.
You are still missing a couple of entries in comparison with the one i provided, did you tried it yet?
Have you tried to disable DPMS? xset -dpms
to reenable it xset +dpms
Have you tried a different cable?
Another thing. That black is as if the monitor is off, or if you move a window there you can see it? If you can see it, then just change the background ā¦
As if the monitor is on and I can move a window or mouse pointer to it but cannot see as its black. So its not like its just a black backgroundā¦ I cannot see the desktop interface at all.
It works on another OS? And you switch the connectors between monitors and always is the same monitor or the one connected to a certain port, also you tried to power off and on the monitor from the in built power button?
If that is the case, and always the same result, then iām left out of ideas.
Tried with PopOS (nvidia version) but did not work. Should I try ubuntu too?
Switched ports on the gpu and on the monitor but still the same results.
I just tried kernel version 5.4, 5.10 with nvidia-driver reinstall and its still not working.
