Abhiroj, thank you for reporting this and helping make Ubuntu better.
1) Could you please provide the full computer model as noted on the
sticker of the computer itself (not from the Bug Description, or the
result of a terminal command)?
2) Did this happen after an update? if so, which specifically?
3) To see if this is resolved in your release, could you please update
your HWE stack via https://wiki.ubuntu.com/Kernel/LTSEnablementStack and
advise to the results?
4) If still reproducible after performing 3), please undo your
WORKAROUND, remove and PPAs installed, and provide the missing
information from https://wiki.ubuntu.com/DebuggingKernelBoot .
** Description changed:
- 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:-
+ Ubuntu 16.04 was working fine for a long time but since recently, while
+ booting, after purple screen the screen goes blank. 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 then switch to the command-line screen or
+ tty1 to get the logs.
- **The Problem**:-
+ I've tried: the `oibaf-drivers` but this didn't help.
- After Boot (i.e. after purple screen),
-
- 1. There is no mouse pointer.
-
- 2. 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.
-
- 3. I wait and then switch to the command-line screen or tty1 to get the
- logs.
-
- **What I have done yet**:-
-
- 1. I have updated my system, with `oibaf-drivers` but still no help.
- `fglrx` is officially deprecated for Ubuntu 16.04 and `amdgpu-pro`
- provided by AMD does not support AMD graphic card of my
- system.Currently, the system is using(I don't 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)
-
- 2. `dmesg | grep -i radeon` shows no error during boot-up.
-
- 3. Running the system in `nomodeset`, which is resulting in highly poor
- graphics performance. It is much deflected compared to ideal.
-
- 4. Not running the system in `nomodeset` but using `startX` in tty1, the
- systemUI restarts again but `mouse pointer turns to a cross` and only
+ Using `startX` in tty1, the mouse pointer turns to a cross and 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
+ 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.
- Please suggest a solution.
+ WORKAROUND: Use kernel parameter:
+ nomodeset
