Please bear with me as This is the last place to resolve the as I have tried different resources available for the problem already, but with no effect.Long story short, Ubuntu 16.04 was working fine for a long time but since recently, It is showing up the black screen after boot.By blank screen, I mean:-
After Boot (i.e. after purple screen),
There is no mouse pointer.
A cursor blinks for a few seconds and screen goes 100% black but still lit, and then after another few seconds, it goes completely dark as if it is turned off.
I wait and then switch to the command-line screen or tty1 to get the logs.
What I have done yet:-
I have updated my system, with
oibaf-driversbut still no help.
fglrxis officially deprecated for Ubuntu 16.04 and
amdgpu-proprovided by AMD does not support AMD graphic card of my system.Currently, the system is using(I don't know whether it is perfectly working or not)
radeon driver(The OSS driver for AMD). For more info, here are the specs of GPU on my system:-
Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun LE [Radeon HD 8550M / R5 M230]
VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
dmesg | grep -i radeonshows no error during boot-up.
If running the system in
nomodeset, which is resulting in highly poor graphics performance. It is much deflected compared to ideal. The fan is running crazy in
nomodeset. The system is using
Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)to render graphics.
If not running the system in
startXin tty1, the systemUI restarts again but
mouse pointer turns to a crossand only folders present on my desktop are visible, but no wallpaper can be seen, no side-dock, no launcher (after the click) and no status bar.The desktop is completely absent though desktop folders are visible and can be opened.
I am open for any solution/fix. I have referred this post but it is of not much help. It asks to install proprietary drivers. In the case of AMD, it easily discards old models hence it is difficult to find supported drivers. Alternatives have been tried out, but it is not solving the problem.
Edit 1:- Properitry drivers are available for the GPU, but after installation system fails to boot.The only option is to uninstall it.
