I have a similar setup, with a different card and running Feisty, but the fade out takes only about 1 second:
Section "Module" Load "i2c" Load "bitmap" Load "ddc" #Load "dri" Load "extmod" Load "freetype" Load "glx" Load "int10" Load "type1" Load "vbe" EndSection [...] Section "Device" Identifier "nVidia GeForce" Driver "nvidia" VendorName "nVidia Corporation" BoardName "NV18 [GeForce4 MX 4000 AGP 8x] (rev c1)" BusID "PCI:5:4:0" Screen 0 EndSection [...] Section "Screen" Identifier "Screen0" Device "nVidia GeForce" Monitor "Monitor0" DefaultDepth 16 [...] EndSection I'm also running with Xinerama enabled, but I doubt that is affecting things. ** Summary changed: - Screen blanks/fades to black really very slowly + Screen blanks/fades to black really very slowly with nvidia-glx -- Screen blanks/fades to black really very slowly with nvidia-glx https://launchpad.net/bugs/57702 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
