Created attachment 347746 [details] cups access log Description of problem: I logged in as an ordinary user, used "su -" and launched system-config-printer from the command line as root. Seemed to work ok except a) can't access Server->Settings and b) when adding a new printer applying the changes fails due to privilege error. Version-Release number of selected component (if applicable): cups-1.4-0.b2.18.fc11.i586 How reproducible: Always. Steps to Reproduce: 1. Log in as an ordinary user 2. su - 3. system-config-printer 4. Server->Settings 5. Try to add a new printer Actual results: Permission denied for the super user(!). Expected results: root is able to do his will. Additional info: I'm attaching access_log and error_log after such an attempt.

You don't need to become root to use system-config-printer. Just use it from your user account. PolicyKit denies access to the root user as a matter of course (see bug #447266). *** This bug has been marked as a duplicate of bug 447266 ***
