KDM/KDE on Slackware64 13.1

by on Aug.29, 2010, under Software

Actually, it’s slackware64-current, but it’s pretty much the same for today’s issue.

Don’t ask me why, but for some reason my girlfriend wanted to start KDM/KDE.
(probably because enlightenment now completely abandoned their piece of garbage login manager ‘entranced’).
So she ran a ton of updates – “slackpkg update ; slackpkg upgrade-all” and rebooted.
KDM came up fine. Then she tried to login and was greeted by:

Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 127

After clicking this away KDE started to load but stopped shortly after that and KDM was greeting her again.

The solution for this was quite simple:
When you upgrade stuff, make sure to install the -new- packages. Usually
$ slackpkg install-new
handles this, but sometimes it misses stuff. Especially if you forgot about doing this for a few upgrades and only do it because stuff stopped working.

Anyhow, the fix is to install the missing packages, especially ConsoleKit, polkit and eggdbus.

# slackpkg install ConsoleKit polkit eggdbus

While you’re at it you might want to consider installing more of the new slackware packages like xf86-video-nouveau-blacklist 😉
