I am using Ubuntu 14.04.03 on a Dell Inspiron 15-5547, AMD Radeon HD R7 M265 dual graphics with the fgrlx-updates drivers. Since the update to kernel 3.16.0.60, when I try to boot into my computer, I am getting this error:

The system is running in low-graphics mode

I have followed the suggestions described here (reinstalled the proprietary drivers via apt-get).

However, the problem persists, when i boot into 3.16.0.60. Kernel 3.16.0.59 boots without problems.

Is there a mismatch of kernel vs drivers, which should be considered a bug? Is there something I can do in order to get graphics working on kernel 3.16.0.60? As a temporary workaround: where can I change the default kernel my system boots into?

EDIT: The problem persisted up to and including kernel 3.16.0.67. I found a bug report in launchpad, which however had no activity. I have updated to 16.04 on the day of release due to this bug and do not have this problem any more.

Start your computer while pressing these buttons: CTRL + ALT + F1 and then enter your username and password and type the following commands:

sudo apt-get update
sudo apt-get -d install --reinstall gdm
sudo apt-get remove --purge gdm
sudo apt-get install gdm

Select gdm

sudo reboot

  • This did not work. In fact when using gdm instead of light-dm my system did not boot even when using the 3.16.0.59 kernel. I had to repeat the steps above and select light-dm. Now I am back to the original problem. – Bruni Feb 17 '16 at 08:00
  • I mean did not boot in a graphical environment, even when using.... – Bruni Feb 17 '16 at 08:21
  • Is that video driver is installed? – GAD3R Feb 17 '16 at 08:26
  • fgrlx-updates is installed (else the system would not run on the 3.16.0.59 kernel) – Bruni Feb 17 '16 at 10:59
