In the "blank screen" setting in screen saver. It was set to blank after 2 min. Put display to sleep when computer is inactive for 3 min. Switch off display in 4 min. Result: screen went blank but did not go into sleep and display did not turn off.
In the "random screen saver" setting in screen saver. Again, same settings as above. GL Text froze and computer became unresponsive. It appears to be GL Text that seems to be an issue. In opening screen saver preferences, and selecting one screen saver, GL text in this case, in running only the preview affected memory and swap (as seen in screen shot with Conky on the right). I captured the screen shot moments before sending my computer unresponsive before exiting it. I repeated the same previews with the other "GL's". GLcells, GLblurs, GLmatrix etc, no problem with these. ** Attachment added: "Screenshot - 11-04-04 - 05:36:29 PM.png" https://bugs.launchpad.net/ubuntu/+source/xscreensaver/+bug/749811/+attachment/1979879/+files/Screenshot%20-%2011-04-04%20-%2005%3A36%3A29%20PM.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/749811 Title: Screensaver will not complete screensaver to sleep mode, PC freezes and must be hard rebooted -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
