[solved] lxdm, slim: startup delay

lynix · 2013-01-26 22:03:03

I'm trying to switch from lightdm to lxdm in order to work around the awesome keymap bug.

When I start lxdm using systemctl start lxdm.service I get a black screen and nothing happens for about 70 seconds. Then the lxdm greeter finally shows up, everything works fine and there are no errors or hints in the logs.

Any idea what could cause the delay? I tried lxdm-git from AUR, but no difference.

Thanks in advance,

lynix

I'm going to modify the topic title, as I tested multiple login managers and the results are weird:

- lightdm: works
- lxdm: startup delay
- gdm: works
- slim: startup delay
- gdm-old: works

Problem is that all login managers that don't suffer the startup delay problem cause the awesome keyboard layout bug...

Okay, solved my own problem (another episode of strace-to-the-rescue)

The login managers in question seem to open a connection to '::1' (the IPv6 loopback) on startup. My ip6tables lacked a rule for accepting all loopback traffic, and as my default target for INPUT is DROP, the connection attempt was dropped and startup therefore delayed until the timeout for connection establishment is reached.

Damn this was weird...

@lynix
Many thanks!!! You saved my day!
Had the same issue after applying systemctl enable iptables yesterday and forget it, today slim needed more than 2 minutes to show, ipv6 filter rule issue..
Many thanks for the tip!
