Could not find DRM device! #217

Closed dvc94ch closed 8 years ago

dvc94ch commented 8 years ago

I'm testing the experimental PR from here https://github.com/sddm/sddm/pull/616. I'm running into an issue where greenisland doesn't correctly detect a drm device. I ran some basic commands and pasted the outputs below.

This is usually related to logind/pam, for example when you login as a user and then sudo su - and try to run the compositor.

If that is the case then login as root from the beginning (at the tty login prompt).

plfiorini commented 8 years ago

Logging in as normal user should also work.

In both cases your distro need to be properly configured to use the logind pam module. All distros should have it.

plfiorini commented 8 years ago

Ops I was too quick and didn't notice you came from the SDDM PR. That's the reason why I haven't merged the PR yet. I need to find out what's the deal with logind and sddm.

plfiorini commented 8 years ago

@dvc94ch silly me i forgot to run the compositor through the sddm-helper which is needed to open a session with logind. the issue is not in the compositor rather in sddm, the PR is now updated although i have other problems with the helper though so it's still not working.

Closing the issue here as it needs to be fixed from sddm.
