[Bug 1377878] Re: PPC - GUI freezes except for mouse pointer

 

"System was installed using Boris/Adam's "agpmode=-1"that worked to
clean up the 14.10 GUI . . . and I've tried various flavors of
"radeonfb" boot parameters . . . "

- don't! My understanding was using "radeonfb" conflicts with KMS which
we want to use nowadays, so try to leave it out and instead use only
"video=ofonly radeon.agpmode=-1"


"Yesterday I ran "sudo Xorg -configure" . . . and generated an xorg.conf file . . . it does show "radeon" as the driver, along with a bunch of other stuff . . . rebooted . . . no difference." 

- Did you move it to it's right place via "sudo mv xorg.conf.new
/etc/X11/xorg.conf"

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?
