Disabling Screensaver

KDE or xscreensaver?

Also try upgrading Xorg.

if you disable the screensaver, you will not be able to use lock screen (managed by xscreensaver). You get better security by turning the box off anyway

Okay, how about replacing my screensaver with another screensaver that blanks screen and requires password, but doesn't use the xscreensaver library that seems to lock up my office workstation?

BTW, here's my xorg.conf file, in case you're particularly gifted with this.

Note I'm using 2 separate video cards and 2 LCD panels in Xinerama mode. I'm on Ubuntu Breezy and have stuck fairly close to the original standard build except have used backports to upgrade mp3 playback, snag BMP player, snatch PHP4, and install the very latest Bluefish and Screem.

Note also that when I was on RH9 and Fedora, the screen lockups never occurred. Also, when I was on regular monitors, the screen lockups didn't occur. (Or was it that I moved from Ubuntu Hoary to Breezy? I don't recall because that monitor change-out sort of all happened at the same time.)

you could try gnome-screensaver . Never used it, but I read a bug report about it (not implementing screensaver configuration, which you don't need anyway )
it should be in apt, so try removing xscreensaver and installing gnome-screensaver. good luck.

It doesn't look like there's anything wrong with your xorg.conf, but why do you have two mice and one keyboard?

What version of Xorg are you using?

a) Stupidity? How do I fix?

b) The latest that comes with standard Ubuntu Breezy with standard updates. I believe that's: 6.8.2? Unfortunately I don't know how to tell. I did man xorg and looked at the bottom.

If there's Xorg 7 available, try upgrading to that.

I seemed to fix the locking by removing xscreensaver-gl with Synaptic.
