Revision 25753, 4.1 KB checked in by jdreed, 12 years ago (diff)
In cluster-login-config: * Use dh_gconf instead of calling gconftool-2 in the postinst (Trac: #550) * Port the rest of the gconf mandatory keys to gsettings * De-support (and Break:) gdm << 2.25.2 * Stop supporting Lucid and cleanup the rules file
