I believe this is due to incomplete or not at all set up Xorg conf which
for some reason is not done for a long time on certain Radeon systems,
so those are without DRI and all the bells and whistles.

Did you try what I mentioned above?

sudo service lightdm stop

sudo Xorg -configure
sudo mv xorg.conf.new /etc/X11/xorg.conf
sudo nano /etc/X11/xorg.conf

[Here some driver options could be set, eg. uncomment pageflip and set
it to "True", save any edits and after that reboot]

sudo shutdown -r now

After a reboot you can check your acceleration with the commands glxinfo
and glxgears -info if it works you will notice the gears running well
even if quickly moving it's window but likely lubuntu gui  will
otherwise remain kinda slow but should be better.

Title:
  PPC - GUI freezes except for mouse pointer

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  During the installation the computer freezes completely except for the
  mouse pointer.  And even that is stuck with whatever shape it happened
  to have at the time it froze.  The steps I have to cause the freeze
  are run Ubiquity to start the installation open a terminal, run
  Ubuntu-bug and let it launch Firefox.  It will freeze every time then.
  Even the consoles (ctrl-alt-f1 etc) are unavailable.  What kind of
  information can I collect and how?
