The patch titled lxfb/gxfb: when blanking with FB_BLANK_POWERDOWN, also turn off the CRT has been removed from the -mm tree. Its filename was lxfb-gxfb-when-blanking-with-fb_blank_powerdown-also-turn-off-the-crt.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: lxfb/gxfb: when blanking with FB_BLANK_POWERDOWN, also turn off the CRT From: Andres Salomon <dilinger@xxxxxxxxxx> The Display Control's CRT_EN can be shut off when we enter FB_BLANK_POWERDOWN in an attempt to save additional power.
