[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)

[Bryce Harrington]

Confirmed on Feisty running gnome-screensaver 2.17.4 with two nvidia
cards and three monitors running Xinerama.  This is when using the
nvidia binary driver.  (I did not have this problem with the "nv"
driver.)

When gnome-screensaver is activated (either through inactivity or via
ctrl-alt-l), the primary monitor fades out for a second, and then
blanks.  At this point, gnome-screensaver has crashed with the following
error message:

gnome-screensaver-Message: Found best visual for GL: 0x21
The program 'gnome-screensaver' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadColor (invalid Colormap parameter)'.
  (Details: serial 246 error_code 12 request_code 1 minor_code 0)

I can attempt to get a backtrace if someone can point me to the -dbgsym
package for this version of gnome-screensaver.
