I'm not a completely new user of Ubuntu/Linux, but I'm still by far a novice.

I also am not 100% certain what all information is needed (and/or how to get it), so please let me know what I'm missing.

My problem is that occasionally, when booting, after GRUB comes up, it will flash a few times and go to a blank/black screen. The display is clearly on and lit, but it shows nothing. No cursor, nothing. It will play the startup sound, but I have to do a hard shutdown and turn it completely back on to be able to log in.

I find it odd because I have a much older laptop (a Fujitsu Lifebook) that has many other problems, but I never have this problem.

I also have taken note that the standard startup process that Ubuntu is apparently going through is not displayed for me. It's my understanding that there is a splash screen that is displayed during boot - I never see it. I consistently, after grub, see a black screen that flashes. Eventually, it will typically load to a blank screen with cursor and then the login screen. Other times, it's the blank black screen that's on.

I've not seen this happen after I've returned from sleep mode. It only seems to happen when I am starting up.

I have a dual-boot with Windows 10, but I am not sure it has any relevance. Also, I apologize for the length but I don't know how to put all the LSHW results into their own separate scrolling window within this post.

In case it isn't mentioned in there, I am on a Lenovo G50-45. It's fine when I boot Windows, usually fine when I boot Ubuntu.

UPDATE 9-2-2015

Results of running "ubuntu-devices drivers" in Terminal:

heather@Heather-Lenovo-Ubuntu:~$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0 ==
vendor   : Advanced Micro Devices, Inc. [AMD/ATI]
modalias : pci:v00001002d00009851sv000017AAsd00003801bc03sc00i00
driver   : fglrx - distro non-free
driver   : xserver-xorg-video-ati - distro free builtin recommended
driver   : fglrx-updates - distro non-free

Check the graphics card driver. Open the terminal and type:

ubuntu-drivers devices  

The output of ubuntu-drivers devices will show a list of graphics card drivers from the Ubuntu repositories that are compatible with your laptop. I would expect that fglrx would be the right proprietary graphics card driver to install for a Radeon APU A4-6000 with R2 Graphics.

The built-in xserver-xorg-video-ati graphics card driver is listed as recommended because it is already installed in Ubuntu 14.04 by default. If you install the fglrx proprietary graphics card driver, Ubuntu will use fglrx without uninstalling xserver-xorg-video-ati, so that you can still boot with the open source xserver-xorg-video-ati graphics card driver in case you have a problem booting with fglrx.

To install fglrx and the Catalyst Control Center for the AMD Radeon graphics accelerator (fglrx-amdcccle), open the terminal and type:

sudo apt install fglrx fglrx-amdcccle  
sudo reboot  

fglrx is no longer supported in Ubuntu 16.04 and later. In Ubuntu 16.04 and later AMD graphics processors use the built-in open source AMD graphics driver by default. Alternatively you can download the latest stable version of the proprietary AMD graphics driver from the official AMD website.

  • Thank you. I ran that and edited my original question with the results. I read, just now, that fglrx is a proprietary ATI driver, yet the results recommend the xorg driver. Should I install the xorg driver instead? Is it only recommending it because it's open source? – Heather B Sep 3 '15 at 5:24
  • I edited my answer with a reply to your comment. – karel Sep 3 '15 at 5:46
  • Thank you so much for all your help. I installed the fglrx driver and I have restarted several times and I've not seen the blank screen again, and I now see the purple screen and the splash screen as I'm booting up, so everything looks to have worked. – Heather B Sep 11 '15 at 3:25
