Just got a new laptop yesterday and proceeded to install Arch Linux using the latest available image (2026.04.01), and utilizing the archinstall script. Was nervous about getting something with an nVidia graphics card (have been avoiding nVidia for 20+ years) and unsurprisingly, I ran into issues. I have been using Arch for probably close to a decade and solely (without dual booting) for about 5 years now so I have some experience, but absolutely none with dealing with nVidia. Laptop is a Lenovo Legion 5i with Intel i7 14700HX and nVidia RTX5050 (+ integrated Intel graphics which I disabled via laptop UEFI)
Here's what I've done so far:
1) Used the archinstall script to install linux-zen kernel, KDE Plasma (and KDE-applications packages group), and plasma-login-manager
2) Attempted to follow the directions here: https://wiki.archlinux.org/title/NVIDIA, including:
a) Installing linux-zen-headers and the nvidia-open-dkms packages
b) Blacklisted nouveau driver (as it didn't appear to be automatic per the wiki)
c) Removed kms from HOOKS array (although I'm pretty sure this was redundant because of the above blacklisting)
d) Added nvidia_drm.modeset=1 and nvidia_drm.fbdev=1 to my kernel parameters in /etc/kernel/cmdline
e) Verified the output of cat /sys/module/nvidia_drm/parameters/modeset is Y
f) Verified the output of cat /sys/module/nvidia_drm/parameters/fbdev is Y
g) Blacklisted simpledrm (as a suggested workaround from the Wiki)
3) Disabled the hybrid graphics of the laptop so it only uses the nVidia graphics
4) Verfied with lspci -k -d ::03xx that the nvidia driver is being used (notably not the nvidia_drm, not sure if that makes a difference?)
I have no issues booting the laptop (including putting in an encryption password and logging in via the Plasma Login Manager. The issue is that following the Plasma Login Manager I get the spinning KDE gear for a bit and then just a black screen with a cursor, which leads me to believe it is specifically an issue with Wayland (have not tried xorg).
Modesetting appears to be working correctly because scaling reverts to a reasonable value part way through the boot process (small text for encryption password since it's higher DPI screen but then corrects), I get a properly scaled login screen and terminal when switching TTY after the DE fails to load properly. I don't believe the "Early Loading" section of the Wiki will be helpful, but perhaps I am wrong.
Since all I can seem to find about making nVidia and Wayland work properly together is ensuring the two above-mentioned kernel parameters are set correctly, I seem to be at a loss... any help would be appreciated.
Thanks.
