Hi all, I know systemd and lightdm are not exactly kosher on ArchLinux, but any help would be welcome. So, I just noticed that OpenGL is using llvmpipe on my laptop, and then I found out that the /dev/dri/card0 node doesn't have the proper ACL set to allow access to my user. Also my user is not in the video group - since I've learned that's not necesseary in "modern" Linux configurations. Considering that I'm running systemd and using lightdm as a login manager - my question is, what subsystem is responsible for settings the ACL: - ConsoleKit - PolicyKit - systemd - lightdm ? Is the proper setup to have pam_loginuid.so, pam_ck_connector.so and pam_systemd.so in the PAM configuration for lightdm? the output of ck-list-session is: Session2: unix-user = '1000' realname = '' seat = 'Seat1' session-type = '' active = TRUE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2011-12-02T18:23:04.193636Z' login-session-id = '' -- дамјан
