Hello Pedro, It took some time for me to install Natty Narwhal, which I did by upgrading from 10.04 LTS. Before the install, I tested gnome- screensaver in the live CD environment to see if the issue occurred with the standard display driver (possibly Nouveau): it does not. I then did a system upgrade, which was necessary to use the Nvidia driver. Having activated this, I installed xscreensaver, xscreensaver-data-extra and xscreensaver-gl-extra, then brought up the gnome-screensaver preferences and set it to use the Substrate screensaver. Clicking the 'Preview' button, the first couple of tests showed the correct white background. I closed the preview and selected another screensaver, then went back to Substrate. The mini-preview window showed the white background correctly, but showing the full-screen preview brought up the incorrect black background. To summarise: the screensaver small screen preview (sorry, I do not know the proper name for it) shows the correct white background, but the full-screen preview still occasionally sets the background to black.
Based on the fact that I have never been able to make this bug appear with another display driver, I'd guess that it's an Nvidia driver issue, though I don't know for sure. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/227244 Title: gnome-screensaver hacks requiring white background are using black background instead -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
