@SK10 we have the same laptop, are you sure the Nvidia drivers are properly loaded?

sudo akmods
sudo dmesg | grep nvidia
SK10 commented 1 year ago

@bayasdev Yeah great laptop. I'm currently on hybrid mode, here's the commands output

@SK10 I'm not sure about Fedora KDE but I tested on Fedora 38 (Gnome) and envycontrol works as expected (gdm uses Wayland and fall backs to CPU copy for external screen).

Maybe they're now defaulting SDDM to Wayland or something that's not entirely compatible with Nvidia.

bayasdev commented 1 year ago

@SK10 please try creating a .conf file inside /etc/sddm.conf.d/ with:

DisplayServer=x11

Reboot and now SDDM should default to X11

SK10 commented 1 year ago

@bayasdev Just tried that, unfortunately the issue persisted.

bayasdev commented 1 year ago

@SK10 when the problem occurs try to open a TTY and capture the X.org logs from /var/log/Xorg.0.log

bayasdev commented 1 year ago

@SK10 I'm reading that Fedora doesn't ship with xrandr so try to install it before switching to Nvidia mode:

sudo dnf -y install xrandr
SK10 commented 1 year ago

@bayasdev here's the log: https://privatebin.net/?b5862a480d7981e4#E4x3HiozD5VUwXZuc9L6QUCtfRHwNiCpD4xXi8abWTGA I do have xrandr installed

bayasdev commented 1 year ago

@SK10 I think I found the problem, Fedora uses /etc/sddm/Xsetup and not /usr/share/sddm/scripts/Xsetup.

Switch to Nvidia mode and run the following commands:

# backup
sudo mv /etc/sddm/Xsetup /etc/sddm/Xsetup.bak

# move Envycontrol generated script to the correct path
sudo cp /usr/share/sddm/scripts/Xsetup /etc/sddm/Xsetup

# also give it exec permissions
sudo chmod +x /etc/sddm/Xsetup

sudo reboot

Let me know if it works 😉

Unfortunately it didn't work. Have I done something wrong?
