Hi, With this setup, something has happened: in xorg, when screen goes to screensaver and after, enters into Standby mode, when I press a key, it keeps black and, to recover screen, I have to adjust brightness manually (by increasing), as if it didn't remember previous value to standby mode. This was something that before didn't happen. Josep On 2 August 2013 20:58, Felipe Contreras <felipe.contreras@xxxxxxxxx> wrote: > On Fri, Aug 2, 2013 at 9:03 AM, Rafael J.
