Fresh Arch Linux Install: LightDM not starting on boot

rhearmas · 2020-10-13 01:49:51

Howdy-do, neighborinos! Hope this topic finds you well.

I have tried absolutely everything, but I can't seem to get LightDM to work properly. I installed it with pacman, and immediately rebooted after installing that and lightdm-gtk-greeter, but it seems that LightDM fails to load when booting with rEFInd. All it tells me is that LightDM failed to load.

I've done my research everywhere but I can't seem to fix the issue; I don't know if it was how I worded the keywords or what, but I can't seem to find a fix for the issue. I've tried reinstalling it and everything; didn't work whatsoever.

Can I get some help with this issue? Thanks in advance.

EDIT 1: oh my, am I so dumb. Here is my LightDM config so you all know what I've got right now.

Could be nice some details, so we can help you, like logs, whatever configurations you have made, any rEFInd configuration, your kernel command line...

Just be verbose with details, because now it’s like “I installed foo yet after using bar it fails, help?”

rhearmas · 2020-10-13 02:15:26

Sorry about that.

No configuration to rEFInd whatsoever besides simply putting in the GUID for everything. I haven't configured LightDM either; it's been left completely unconfigured after its install. Log-wise, I am unsure on how to provide everything if I have no way of accessing my window manager (i3) since the error prevents me from typing anything.

first off, if you didn't configure lightdm, of course it doesn't work.

second, start your WM with xinit/startx. That's been the standard way for decades.

third, https://wiki.archlinux.org/index.php/Li … in_clients

fourth, the DM not starting doesn't prevent you from typing. Switch to another VT.

2) tried both commands. returns with Fatal server error: no screens found(EE).
3) got that to work with this post here. thanks!
4) also got that down. unofficial Discord helped me out.

I checked all of those links as well.

I got some more info on why it isn’t starting by checking /var/logs...

What’s odd is that I have lightdm-gtk-greeter installed, so I’d expect this to work normally.

This is an Optimus system and it looks like you used nvidia-settings/xconfig to create a static config for the nvidia chip, which does not work in general and also the GPU seems deactivated (bumblebee/bbswitch?)

Work through https://wiki.archlinux.org/index.php/NVIDIA_Optimus - decide how you want to use the system and configure it accordingly.
In any event remove the static server config.

rhearmas · 2020-10-13 12:44:55

Tried the steps on the wiki under the Use NVIDIA graphics only section on the link you sent -- created the shell script, made it executable, had it run by placing it at the top of the Seat tag. Still didn't work. Xorg.0.log still gives me the same "no screens found" error.

While we're at it, here is my LightDM config. I'll pin this link to the original post.

Some lightdm script does entirely not cut it, this is just for using the nvidia GPU and the IGP as a VGA provider. You'll still ahve to properly configure the server and again: the GPU looks powered down anyway.
Please actually read through the wiki and follow-ups, don't just copy some random blue box.

Should I go ahead and install bumblebee on my system? Or is there another way for me to resolve this issue?

There is no cookie-cutter solution here.

rhearmas · 2020-10-13 13:42:04

I've tried to work through that entire page. Nothing has worked and I'm still stuck at this error. I don't know if reinstalling Arch is a good idea or what, I'm honestly at a dead end here.

seth · 2020-10-13 13:44:24

if reinstalling Arch is a good idea

Certainly not.

How do you prefer to use the hybrid graphics?

I'd usually like to use my NVIDIA graphics whenever possible. Games mostly serve well for this; the better GPU for games and Intel for everything else.

seth · 2020-10-13 13:56:22

So a hybrid setup, bumblebee or better prime - depending on the capablilities of your GPU and the driver version you can use.

You want to pursue https://wiki.archlinux.org/index.php/PR … er_offload

rhearmas · 2020-10-13 14:14:11

I went to that link and followed the instructions. I installed the package and added the necessary configuration to xorg.conf. I rebooted my machine after removing bumblebee, but nothing seems to have worked, once again. I might consider reinstalling Arch since this is a new install with no personal files on it.

seth · 2020-10-13 14:15:15

You will end up w/ the exact same situation.
xorg log?

rhearmas · 2020-10-13 14:20:20

I had two files in my /var/log folder: Xorg.0.log and Xorg.8.log. I've made a paste for both files: Xorg.0.log is here and Xorg.8.log is here. I don't know if there is a difference between both files.

You're still using an nvidia-settings generated config file…

I'm literally dumb. I'll fix that. Is there a way to get the proper names of all the devices (like lspci)?

Xorg probes them and you don't need them (for the task at hand)
