tint2 doesn't render on debian multi-head fglrx

[GoogleCodeExporter]

What steps will reproduce the problem?
1. install fglrx
2. execute "tint2"

What is the expected output: tint2 taskbar

What do you see instead:
black bars in the right dimension and position. The taskbar is functional too 
(when I right-click where a window button should be it tries to close that 
window)

output:

uke@Wheatley:~$ tint2
real transparency off.... depth: 24
xRandr: Found crtc's: 3
xRandr: Linking output DFP4 with crtc 0
xRandr: Linking output CRT2 with crtc 1
tint2 : nb monitor 3, nb monitor used 3, nb desktop 4
tint2 : not icon_swallow
tint2 : not icon_swallow
tint2 : not icon_swallow
^C

What version of the product are you using? On what operating system?

luke@Wheatley:~$ aptitude show tint2

Please provide any additional information below.

Seems only to happen since I installed fglrx. I'd go back to drm or mesa to 
test it, but it's too complicated and I don't want to fuck up my system...

The same occurs for me with radeon (open source driver), not fglrx closed one.

confirmed with a fresh 12.04 (x64) install on a new hard drive. Same PC 
demonstrated the same problem after updating 11.10 (i386) to 12.04.

Here is a patch.
It seems XRRGetScreenResourcesCurrent() returns a fantom monitor on some 
configs.

i have build tint2 with this patch but unfortunately i still observe this 
behavior, e.g. tint2 reserves space and reacts to interaction but is fully 
transparent (because compositing is enabled, otherwise it's black square).

This is the output from tint:

real transparency on... depth: 32
xRandr: Found crtc's: 3
xRandr: Linking output HDMI2 with crtc 1
xRandr: Linking output HDMI3 with crtc 2
tint2 : nb monitor 3, nb monitor used 3, nb desktop 6
icon with depth: 24
tint2 : not icon_swallow

What can i do to help debug the issue? // this is Arch with Openbox, notebook 
on a docking stating set up via XRandr.

In my case, they were all equal to 0 for the last (non-existent) detected 
monitor.
Seeing that you use HDMI2 and HDMI3, maybe in your case it is the first monitor 
that is wrongly detected.

To help, you should try to add a debug print on the following values :
crtc_info->x
crtc_info->y
crtc_info->width
crtc_info->height

after upgrading to Ubuntu 12.10 (and the new tint2 package), I had the same 
problem. Fixed after building tint2 from source with the patch listed in 
comment #5
