I think this is caused by the open source ATI drivers. This is how I
managed to bypass the problem, if anyone else has the same issue:
Get a liveCd/LiveUSB and boot normally without any options. Let plymouth
do its work and once you get to the stage that the GPU is being reset
every few seconds press Ctrl+Alt+F1 to drop to terminal and execute the
following commands:
#sudo stop gdm
#sudo nano /etc/X11/xorg.conf
Type in the following set of commands then save and exit.
# /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Driver "fbdev"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection[
This would tell X to use framebuffer instead of the actual drivers for
your graphics card. After saving the file all you need to do is to run
#sudo start gdm
And you will get the LiveCD desktop and you can install from there.
After it is finished you can restart your computer and either use the
same xorg.conf file or install the official ATI drivers and let them
take over. Whatever you do though don't just use the open source drivers
because you won't be able to boot and have to do all the above steps
again.
