[SOLVED] lightdm fails to start when invoked from terminal
How can I successfully manually restart lightdm? I have lightdm enabled through systemd and it normally starts up and runs without error from boot to shutdown.
However, if I try and run
$ systemctl restart lightdmOr try and start lightdm from the terminal
$ systemctl start lightdmXorg and lightdm fail to start.
In the lightdm.log and x-0.log in /var/log/lightdm, neither reference any issues beyond both a keyboard and a failure to access a directory, so I am not sure if either are relevant to my problem. Will post in case they are informative:

Either that or an improperly configured nouveau driver. Though, for whatever reason, none of the lightdm logs mention this. Then again, it is worth mentioning that when I switch to a virtual terminal, either with lightdm up or having manually quit it, kernel audit messages start to appear randomly throughout the console. Might be relevant since I have read on one particular forum post that an improperly configured nouveau driver can cause the kernel to print audits to the console.

Re: [SOLVED] lightdm fails to start when invoked from terminal
Would it helpful for me to post the lightdm config files, Xsession script in /etc/lightdm/, and my xorg.conf file?

Re: [SOLVED] lightdm fails to start when invoked from terminal
It appears this might have something to do with my nouveau driver. I recently tried to reconfigure my device in order to setup PRIME (i.e. the optimus work around), enabling the kernel parameters:
quiet splash nouveau.config=NvBios=PRAMIN drm.debug=14 log_buf_len=16MI also set the nouveau module to load in /etc/mkinitcpio.conf. When I did these things and rebooted, lightdm failed to start. When I only disabled the nouveau module in /etc/mkinitcpio.conf and rebooted, lightdm was able to start again.
I also tried to start an x server via xinit after lightdm crashed initially. I got this x-log:

(EE) Server terminated with error (1). Closing log file.This makes me think the nouveau driver might be somehow problematic. I am unsure where to go from here though. My nvidia card doesn't even seem to be configured to display under lightdm's default (i.e. when it successfully starts at boot):
xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x44 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 0 name:modesetting
Provider 1: id: 0x1b3 cap: 0x0 crtcs: 0 outputs: 0 associated providers: 0 name:modesettingI.e. that, for whatever reason, provider 2 (which gpu?) 0 for everything. Also, that, for whatever reason, both cards are set to "modesetting"

Re: [SOLVED] lightdm fails to start when invoked from terminal
Additionally, my xinit is configured to use the nouveau driver mainly. At least, I think that is the case, since it sets the nvidia card to "display 0". However, when I switched the card numbers for "Displays 0 and 1", that did not fix anything either. I.e. the same error occurred.

Re: [SOLVED] lightdm fails to start when invoked from terminal
Figured out the problem. Uninstalled nouveau and generated a new xorg.conf file. It changed the drivers for both cards to "modeswitching".
Now I can start lightdm, xserver, and any other desktop environment from the command line.
Xorg.conf:

EndSectionFor now, it seems I will not be able to utilize my nvidia card until I figure out optimus. If anyone comes across similar problems with optimus enabled systems (i.e. manual startups of desktop or xorg environments leading to seg faults or similar errors) I guess for now just uninstall nouveau. Will try proprietary drivers in a few days. Will post results in a new thread later*
