xorg log (savage)

I have the same problem on my Presario 700. It has a savage video card, which
is very likely what the original reporter has also. vbetool works, xset does
not. (Breezy RC)

Yes, the T21 also has a Savage.

In the upstream BTS I found this bug report:

    https://bugs.freedesktop.org/show_bug.cgi?id=2025

Quoting from its log:

    I added backlight control after 6.8.x was released.

The current xorg in Breezy is version 6.8.2.

The problem has reappeared in Dapper. "xset dpms force off" does turn off the backlight, but the screensaver does not seem to do it. I have chosen "blank screen" in the screensaver preference. Can it this time be a screensaver or default preference problem ?

Actually, it shuts off the backlight eventually. I have been running on AC power, and the display power off time is then long...

But it would be better if it would turn off the backlight as soon as it blanks the screen. But that's a screensaver bug, right.

If Jeremy would confirm, we could close this bug.

Running 5.10 on an IBM A20m with a Rage Mobility AGP 2x 8mb. No matter what I add to xorg.conf, the backlight will not turn off.

xset dpms force off only blanks the screen with backlight, not entirely off.

Hannah, you have a completely different video card. I suggest you file a new bug.

It seems a technical solution has been found to blanking the screen, but that the screensaver does not do this as expected. Re-assigning to gnome-screensaver

the comment from Tormod Volden suggests it is solved, no ? gnome-screensaver currently has no option to set the timeout for dpms in the settings, you can try to set it with gconf-editor if the time seems to long (note that its added to the normal screensaver timeout (the dpms timer starts counting after the screen was blanked). imho this is fixed and should be turned into a whishlist bug for a settings option in g-s-s preferences

> you can try to set it with gconf-editor

Do you mean the ac_sleep_display (and battery_sleep_display) in the /apps/gnome-power-manager entry?

There is already a GUI setting in gnome-power-preferences.

> imho this is fixed and should be turned into a whishlist bug

Yes, the original bug (backlight) is fixed. The proposed wishlist bug is fixed by the GUI setting in gnome-power-preferences, I would think.

The only issue left is that it is not so intuitive for the user that the blank-screen time is set in one preference tool, and the turn-off-screen time in another. But it is technically correct :)
