[SOLVED] Delay LightDM Boot?
I'm running Arch Linux with SSD. LightDM glitched up with NVIDIA Driver where the Mouse Cursor is pointing at (on Desktop Screen after login).
I want to delay LightDM on boot. So that way, I'm hoping this will solve my problem without logout and re-login.
Is there a way for me to delay LightDM Boot? Similar to sleep command.
SOLVED: I've found out what I did wrong. My Laptop has both Intel GPU and NVIDIA GPU. If I just add nvidia nvidia_modeset nvidia_uvm nvidia_drm to MODULES in /etc/mkinitcpio.conf. I still get cursor issue.
But, if I add i915 to MODULES in /etc/mkinitcpio.conf. I don't have this problem at all.
For Laptop users. If you're adding NVIDIA GPU to MODULES. Make sure you add Intel or AMD GPU to MODULES too. Even you set NVIDIA GPU as the only GPU. You can still face same issue as I did without adding GPU from your CPU to MODULES.

or if that isn't sufficient you'll want to enable early KMS: https://wiki.archlinux.org/title/Kernel … _KMS_start

It doesn't work! Same issue happened.

Re: [SOLVED] Delay LightDM Boot?
The second approach should for most purposes fix things that have to do with the loading race (... did you forget to run mkinitcpio -P after adjusting the file?). If you still think you can/want to solve this with a delay you can add an ExecStartPre=/usr/bin/sleep 5 or so to the lightdm service file. https://wiki.archlinux.org/title/System … ided_units (whereas the simplest approach would likely be specifying a drop-in file)
