Review of Linux Compatibility

The Lenovo H515s is a small (dimensions: D x W x H = 385 x 105 x 305 mm³) desktop PC, which is compatible with Linux, e.g., Ubuntu 12.04 was successfully installed on the system.

Hardware Specification:

  • Weight: 5 kg
  • Processor: AMD A6-5200 (with integrated graphic unit Radeon HD 8400)
  • Power Supply: Separately, 65 Watt (3.25 A / 20 V)
  • RAM: 4 GB (DDR3-1600) partly used for the graphic unit
  • Mainboard: Lenovo
  • Optical drive: Panasonic PLDS DVD-RW DH-16ACSH
  • Harddisk 500 GB Western Digital Blue WD5000AAKS

Furthermore, the H515s is shipped with a wired keyboard and a wired mouse. The PC can be bought without a Windows license and will be equipped with pre-installed DOS as operating system in this case.

Processor:

The prozessor is a AMD A6-5200, which is normally used as a laptop processor (25 Watt). The Radeon HD 8400 graphic unti is integrated into the processor and uses some part of the RAM for itself.

BIOS:

In order to be able to boot Ubuntu on the H515s and to install it on the system, the following BIOS settings are needed:

Menu "Security"
    > Secure Boot: Disabled

Menu "Startup"
    > Primary Boot Sequence: first DVD, second Harddisk
    > CSM: Enabled
    > Boot Mode: Legacy Only
    > Quick Boot: Enabled

Menu "Exit"
    > OS Optimized Defaults: Disabled

Graphic:

If a HDMI monitors is connected to the H515s it can happen that a black frame appears on the monitor, although the fullscreen resolution was used. In this case the screen settings have to be tuned with the “aticonfig” tool. It is necessary to execute the following command (only once needed)

sudo aticonfig --initial

Afterwards, the xrandr program can be used after each boot to set the screen resolution (it is recommended to add this command to a init script or the start script of the desktop environment)

xrandr --rate 50
aticonfig --set-dispattrib=DFP1,sizeX:1920 # to set X resolution
aticonfig --set-dispattrib=DFP1,sizey:1080 # to set Y resolution
aticonfig --set-dispattrib=DFP1,positionX:0 # to set X position to 0
aticonfig --set-dispattrib=DFP1,positionY:0 # to set Y position to 0
