How to install the proper AMD Radeon graphics driver for LEAP 42.2?

English Install/Boot/Login

Hi.
I installed OpenSUSE 44.2 and having some problems with the graphics. Namely,

  1. the blue light in the upper left corner is covering nearly an 1/8 of the screen, which can be fixed by setting the renderer backend to XRender
  2. On the main screen the mouse pointer is becoming hidden when the mouse enters the middle to down horizontal area of the screen
  3. the resolution of 1920x1200 is not shown, but the same thing was on debian 8 and I fixed it on each boot with cvt, xrandr --addmode, xrandr --newmode
    I presume it’s the drivers because on debian 8 i manually installed them there too

my output of the program lscpi is:
“01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM]”

Any help will be appreciated

not enough info. redo with:

/sbin/lspci -nnk | grep 'VGA\|3D\|Display' -A3

Here is the output

/sbin/lspci -nnk | grep ‘VGA|3D|Display’ -A3
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM] [1002:6611]
Subsystem: ASUSTeK Computer Inc. Device [1043:85f1]
Kernel driver in use: radeon
Kernel modules: radeon

Meanwhile the mouse is now showing in the bottom half of the screen if I repeat the procedure from Debian with cvt, xrandr --addmode, xrandr --newmode.
Only issue 1) remains, which is not that much time critical or essential for me.
