disabling flickering of monitor b4 screensaver invocation


hi all,

I'm running GNOME desktop (Debian Etch) on a DELL M65 laptop. Is it possible to disable the flickering of the monitor when the screensaver is invoked? I still would want to have the screensaver but sometimes the flickering gets annoying.

tia,

My first question would be what video driver are you using ?

Code:
user@it-etch:~$ cat /etc/X11/xorg.conf | grep Driver
        Driver          "kbd"
        Driver          "mouse"
        Driver          "nvidia"
if your system has a nVidia graphics controller and you are using the 'nv' driver (or even worse the 'vesa' driver) installing the proprietary nvidia driver will probably resolve the video issues you are experiencing.

Just a guess, since I'm sure that laptop comes with several different graphics controllers. Let us know what video card is in the laptop and we can get you steered in the right direction.

If you are unsure what video controller is in your laptop, post the output of the following command: lspci

I'm using an nVIDIA Quadro FX 350M adapter. Now I've tried changing the driver from nv to nvidia via "dpkg -reconfigure xserver-xorg" following the debian wiki HOWTO guidelines. However, the system hung up during installation at the very last stage. I had to revert back to the backed /etc/X11/xorg.conf file. Maybe I'll give another shot.
