Whenever I tried to install Ubuntu / Debian or even booting live CD, it say
"low graphics mode" and always ends up with the console. I tried googling a
lot and find that the problem is with Radeon graphics drivers and couldn't
find any optimal solution.
Try installing the ATI binary blobs.
I would recommend installation from an alternate ISO/image of Ubuntu.
Installs much faster than the GUI install. Set the default to console
login. Install the ATI binaries and invoke X. If it falls back to the
console, see the error in the logs. This will give you pointers.
I've a AMD desktop with a Radeon card with HDMI and VGA interface at
home. I was able to get display on the HDMI display while installing
Ubuntu though to a max of 1440x900 resolution. Post installation, I
installed the Radeon 5450 (my card) drivers from the Dell site and
then was able to get full HD output.
If the laptop has a dual hybrid-GPU setup, things might be a bit more
complicated to setup. I was trying to follow all the guides to setup
the dual hybrid GPU on my wife's laptop using Debian/Ubuntu and none
of them worked. Then I figured out that there are multiple ways that
the dual hybrid GPU might be configured on the laptop. For instance in
my case, it was always the intel GPU that was exposed to the OS and
all the intensive graphics work, the intel GPU offloaded it to the AMD
discrete GPU and then rendered the result. So installing a fairly
recent version of kernel (Debian Jessie) and enabling just the intel
GPU first before installing the radeon driver solved the problem for
me. So you might have to do some research before trying the various
howto guides. If you don't understand any of the terms I have used,
please feel free to search for them and read up.
Thanks & Regards,
