black screen

[negatratoron]

Setting up sddm on gentoo linux. When I start it by running /etc/init.d/xdm start I just get a blank screen. When I run sddm --test-mode it just says "Aborted", no useful output. (And when I run that from a terminal window inside an existing X session, I get some output followed by a message that says "Display server failed to start").

My /etc/conf.d/xdm contains DISPLAYMANAGER="sddm". The sddm user is in the video group.

The files /var/log/Xorg.0.log and /var/log/sddm.log do not show any errors.

Here's my Xorg.0.log: http://lpaste.net/1679363600356999168

And sddm.log: http://lpaste.net/350231 (The "Initializing..." at 13:15 through to the end shows my latest attempt to start sddm (as well as stop it using /etc/init.d/xdm stop))

Aren't you using the wrong init script? Shouldn't it be /etc/init.d/sddm start instead?

@peterhoeg /etc/init.d/xdm is correct for those on Gentoo still using OpenRC - xdm is a "virtual" for all kinds of login managers and diverts to whatever is configured - in this case sddm.

Hey, I got past this error on my machine. I believe that what solved it for me was to install the nvidia driver that came with my distro instead of the one from nvidia's website. I'm not sure if there's any other info SDDM could have output anyway.

There is a Fedora bug on this also: https://bugzilla.redhat.com/show_bug.cgi?id=1350107
I am now having this issue on two different laptops... doesn't occur on my desktop system.
I've been having the issue since June, 2016 - and have resorted to KDM for the affected systems.

KDE bug is here: https://bugs.kde.org/show_bug.cgi?id=364835
