I'm commenting here because I have a very similar problem (and have had
said problem for some time), but which manifests in something of the
opposite way:
After boot my script, as yours, does `echo OFF >
/sys/kernel/debug/vgaswitcheroo/switch`. Several seconds later, I begin
receiving
[ 50.069942] radeon 0000:01:00.0: couldn't schedule ib
[ 50.069951] [drm:radeon_cs_ib_chunk] *ERROR* Failed to schedule IB !
in the kernel log/dmesg 50-100 lines/sec
At this point xrandr reports outputs for both the discrete and the
integrated video cards. So, for example, if I have no external devices
plugged in I'll receive:

Upon connecting or disconnecting an external monitor, putting the computer into
standby gdm crashes and I get the following lines onscreen and in the kernel
log:
[ 922.267146] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than

Then gdm starts. At this point the IB scheduling errors stop and the
xrandr outputs associated with the disabled video card no longer appear.
The above also occurs if I log out of a gdm session.
After this point, subsequent device changes and session logouts occur
normally until the computer is restarted.
I haven't been keeping track (I haven't had time to mess with this) of
this rigorously, but while the IB scheduling errors only showed up in
13.10, the atom_execute_table_locked/op_jump errors have occurred since
at least 12.04, I believe. I believe the extra displays part of the bug
has occurred since at least 12.10, but possibly before. These are all
reported together because they all occur in a very predictable sequence.

Title:
Multiple graphics problems, regression
Status in “xserver-xorg-video-ati” package in Ubuntu:
Incomplete
Bug description:
Graphics driver will regularly freeze for ~30 seconds, emitting this
type of messages over and over:
[ 1652.976556] [drm:atom_execute_table_locked] *ERROR* atombios stuck
executing CC98 (len 62, WS 0, PS 0) @ 0xCCB4

I can reproduce this failure at any time by changing the screen
brightness on the laptop. It sometimes happens spontaneously as well,
and sometimes when I start the "Screen Display" settings app.
When it finally unfreezes, I get incorrect screen resolutions,
incorrect number of monitors, a frozen mouse pointer on screen (on top
of everything else, even on top of the real mouse pointer), and
sometimes rendering glitches. It will continue emitting this type of
message:
[ 2747.265512] [drm:radeon_cs_ib_chunk] *ERROR* Failed to schedule IB !
[ 2747.310454] radeon 0000:01:00.0: couldn't schedule ib

These messages will not cease unless I reboot, adding 50 lines/second
to my logs.
This is a clean install of Ubuntu 13.10, running Gnome shell (I
installed gnome-core). Previously this laptop ran 12.10 and while I
did see the occasional glitch it was never this severe.
I should also add that I have a script which switches off the discrete
graphics chip on startup (through echo OFF >
/sys/kernel/debug/vgaswitcheroo/switch). I will deactivate this to see
if it make any difference.
