Hi, it's probably not a driver related issue. At least you don't care for the correct driver. The Radeon driver is pre-installed and used for your Radeon graphics. The nouveau driver can't handle your AMD (the graphics brand formerly known as ATI) at all, since it's a driver for NVIDIA graphics. A workaround probably could be to migrate from "turn monitor off after 15 minute" to "never" do so. However, in my experiences with Ubuntu flavours that suffer from this screen blanking issue, the screen comes back, if you push Ctrl + Alt + F1 (or F2, F3 ... F6) and right after that Ctrl + Alt + F7. "nouveau (/nuːˈvoʊ/) is a free and open-source graphics device driver for Nvidia video cards" [1] "Radeon (/ˈreɪdiɒn/) is a brand of computer products, including graphics processing units [...] by Radeon Technologies Group, a division of Advanced Micro Devices (AMD)." [2] "This guide shows you how to use the open source Radeon driver for some ATI/AMD graphics cards and APUs, which is part of the xserver-xorg-video-ati package. This driver provides 2D and 3D acceleration in your video hardware. For the most recent releases of Ubuntu (and its flavours) this driver is usually as fast as the closed-source, proprietary fglrx driver (called AMD Catalyst) from AMD Inc. Furthermore the Radeon driver supports some older chipsets that fglrx does not. The Radeon driver is already pre-installed in Ubuntu."
