I am also experiencing this bug. I have a IBM Thinkpad X41, and running the latest version of Feisty, clean installed, and using thinkfinger, following the guide on the Ubuntu wiki.
Logging in via gdm works fine. sudo from a terminal works fine. gksudo does not appear - and even after swiping a finger, the application does not appear. A "killall gksu" is required in order to execute the application. If this is not done, then further sudo-s and gksudo-s will function as they did without fingerprinting - ie. sudo will not ask for a fingerprint, and gksudo will appear and ask for a password, as it did before. If gksudo was run from the console, then a Ctrl+C will do the same job. The fingerprint is correctly verified though, as killing gksu without a valid fingerprint will not launch the application. Does anyone know where this bug lies? With gksudo (and it's implementation?) I have googled a fair bit for this - and collected many opinions. One is that gksu/gksudo does not have permission to grab the screen because it is being executed by pam_thinkfinger which is being run as root. Does anyone know if this bug applies to any other distros, or is it specific to Ubuntu too? -- modifying PAM configuration could break gksu https://bugs.launchpad.net/bugs/86843 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
