page_seven Member Registered: Jun 2010 Distribution: CRUX 3.0 Posts: 76 Rep:	tty dpms doesn't turn off backlight. doing "setterm -blank force" 2 times will I'm using crux with kernel 3.16.1 on an HP 8510p laptop. lspci says video card is Code: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV630/M76 [Mobility Radeon HD 2600] If I switch to a tty right after boot and try `setterm -blank force`, the lcd and the backlight are turned off the first time. Doing `setterm -blank poke` to turn the screen back on and then doing `setterm -blank force` again results in the lcd turning off but the backlight staying on. After that the result is always lcd off, but the backlight on, unless I do `setterm -blank force` twice in a row which leaves the lcd and backlight off. dpms in Xorg works perfectly though. I booted latest Fedora and OpenSuse and it is the same in them. Last edited by page_seven; 08-20-2014 at 02:44 AM.
