The current fbdev blank is correct. Normal blanking doesn't power down the hsync or the vsync signals. If you look at fbdev drivers you will see this type of behavior. If you want a full power down then a FB_BLANK_POWERDOWN is needed. As for the blacklight that is a another problem not related to this issue. The fbdev layer sends a event to the backlight layer to tell it to power down. That powerdown happens for the backlight in all cases except FB_BLANK_UNBLANK. How is your backlight setup. Is the backlight handled via the DRI driver or acpi? > Signed-off-by: Johan Hovold <jhov...@gmail.com> > --- > drivers/gpu/drm/drm_fb_helper.c | 2 +- > 1 files changed, 1 insertions(+), 1 deletions(-) > > diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c > index 1b49fa0..9008583 100644 > --- a/drivers/gpu/drm/drm_fb_helper.c > +++ b/drivers/gpu/drm/drm_fb_helper.c > @@ -389,7 +389,7 @@ int drm_fb_helper_blank(int blank, struct fb_info *info) > break; > /* Display: Off; HSync: On, VSync: On */ > case FB_BLANK_NORMAL: > - drm_fb_helper_off(info, DRM_MODE_DPMS_ON); > + drm_fb_helper_off(info, DRM_MODE_DPMS_STANDBY); > break; > /* Display: Off; HSync: Off, VSync: On */ > case FB_BLANK_HSYNC_SUSPEND: > -- > 1.6.6 > > ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
