AMD Kabini Graphics not working properly Thinkpad e145 Ubuntu 16.04

Asked by ateneto

Hallo,

I use Ubuntu on a Thinkpad e145.
GUI, Settings, Details, Overview:
Processor: AMD A4-5000 APU with Radeon(TM) HD Graphics × 4
Graphics: Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)

I just upgraded Ubuntu 14.04 to 16.04.
After the upgrade I experience several problems with my graphics card.
- I can no longer change brightness with the hot-keys of my notebook
- I can no longer connect an external monitor or projector through my vga port, hot-key not working for changing display mode, external display / projector not detected
- there is flickering when I watch a movie

lspci -nn | grep VGA00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8330] [1002:9832]

After start up I get the following error message:
Could not apply the stored configuration for monitors

After the update the graphical grub boot process stopped working so I changed to
GRUB_CMDLINE_LINUX_DEFAULT="text"

After I changed to text I am now able to start up Ubuntu correctly. Before I had to use recovery mode.
But now I am getting the "Could not apply the stored configuration for monitors error message".

This is as far as I got by myself by looking around for solutions.
I can now work with Ubuntu 16.04 but unfortunately my experience is worse than 14.04.

Any help to get my external vga port to work would be highly appreciated.

Thank you!
Sebastian

I am aware of this: http://www.omgubuntu.co.uk/2016/03/ubuntu-drops-amd-catalyst-fglrx-driver-16-04

But the information here is not sufficient for me to resolve my issues.
I haven't managed to use the alternative driver solutions listed here.
Also I don't know what the best way is to enable my vga port and improve video quality.

Did you have the proprietary driver installed when you upgraded?

Thank you for the quick reply!

I used the proprietary driver that was recommended under "additional drivers".
I think it was the now discontinued fglrx driver.

Yes I used the proprietary driver when I upgraded.

I just updated the kernel to 4.4.0-38

The problem remains:
- after upgrading external graphic ports VGA and HDMI stopped working: Unsolved (AMD driver related)
- after upgrading the graphical boot crashes when propted to enter the password for the hard drive encryption: Solved by deactivating graphical boot (bug?)

I guess the lesson learned is: Check if everything works before upgrading.

If I get no more answers I will go back to 14.04
Any help is still highly appreciated.

I went back to the Olibaf driver:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

When I do
* Then to test the VDPAU driver with mpv use:
$ mpv --hwdec=vdpau yourvideofile

then my video plays without flickering. It seems to be an imrovement.

When I do
* To test the XvMC (e.g.) r600 driver edit the file /etc/X11/XvMCConfig and insert:
/usr/lib/dri/libXvMCr600.so

and restart the X server. Then to test it with mplayer:
mplayer -vo xvmc yourvideofile

mplayer won't play any video.

followed this:
http://www.phoronix.com/scan.php?page=article&item=ubuntu_1310_oibaf&num=1

sudo apt-add-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade

Using Olibaf resolves a couple of small issues.
Movie playback improved
FLASH videos are working

VGA and HDMI ports are still not working
