I am trying to build a computer with the following hardware:
MOBO: ASUS A68HM-Plus
CPU: AMD A8-7680
RAM: 16GB (2x8 GB) Patriot Viper 3, DDR3 1600 MHz
DISPLAY: LG 25UM58
SSD: SAMSUNG 1TB
I had problems to make it working with Ubuntu 18.04 so I moved back to 16.04. The first think I had to face was the blank screen at login, so I added "nomodeset" to Grub as suggested by several blog entries. Then, once the system is up and running, from terminal I checked the video driver in use by using the command lshw -c video but there is no "driver=" at "configuration:" entry. Then I also used lspci -nnk | grep -i vga -A3 and indeed amdgpu was listed in "Kernel modules:" but no entry for "Kernel driver in use:". The amdgpu driver should be pre-installed in Ubuntu 16.04+ but I tried also to reinstall: nothing changed. As result, the video is only at 1024x768.
