I've built some CentOS 5.5 64-bit systems straight off the DVD, full installs, and the Gnome screen lock (manually invoked or automatically via the gnome-screensaver) does not allow the user to unlock the screen. The only fix appears to be ctrl-alt-F<1 - 5> then have the user log into the tty session, type pkill -f gnome-screensaver, log out, then ctrl-alt-f7 to return to X.
These systems are standalone, so there is no option to remote in, and the display is never unplugged from the system as some of the RedHat bugzilla reports show.
I did try a yum update but the problem persists, so I suspect the issue has not been fixed, or if it has, has not been released via the yum default locations.
The screensaver and manual screenlock options must be enabled, so disabling them is not an option.
I've also developed a cron job to restart gnome-screensaver every few minutes.
I've got other systems, built back when CentOS 5.0 was out, that do not experience this problem. I've built newer systems with CentOS 5.4 and 5.5, yum updates, and I don't think they have experienced the problem either. I _think_ the issue, thus far, appears to be a full install of all packages from the DVD, which is how I build various standalones.
Does anyone have an update on when this will officially be fixed?
Thanks for any insights.
