Hi, Environment: I am using CentOS 5.3 operating system. I upgraded xorg of centos to 7.3. I am using intel 945 GM board. My xorg server version is 1.4.2 and inetl driver version 2.4.3. gnome-screensaver version is 2.16.1-8.el5. Problem: I connected another system of same hardware using VGA output. Now I can see clone of my system on secondary display. I enabled screensaver with 1 minute period and also enabled locking feature using gnome-screensaver-preferences. After 1 minute screensaver appeared on both primary and secondary displays. But when I move mouse or press any key, Screen saver unlock dialog is not appearing. But when I type password, I am able to comeout of screensaver. So Screensver unlock dialog is there but it is not visible. When I remove secondary display, I mean when I am in single display mode screen saver unlock dialog is visible and working fine. So what could be the problem that causing screensaver unlock dialog window to appear/visible in clone/extended monitor mode. Please help.
