How to run two_linux_panda

[Zachary]

Hello,

Thanks again for your work.

I have applied your patch, and the instances run correctly.

However, there is only one linux widow showing on top-left of the screen.
This is my config of nit_fb:
...
	<start name="linux.1">
		<binary name="nit_fb"/>
		<resource name="RAM" quantum="4M"/>
		<provides>
			<service name="Framebuffer"/>
			<service name="Input"/>
		</provides>
		<config xpos="1" ypos="0" width="510" height="382"/>
	</start>
	<start name="linux.2">
		<binary name="nit_fb"/>
		<resource name="RAM" quantum="4M"/>
		<provides>
			<service name="Framebuffer"/>
			<service name="Input"/>
		</provides>
		<config xpos="513" ypos="0" width="510" height="382"/>
	</start>
...

It is very strange that the output of the log is different from my config: 
...
[init -> linux.2] using xywh=(513,513,510,382)
[init -> linux.1] using xywh=(1,1,510,382)
...

That is the whole run script:

assert_spec platform_panda

Is there somethig wrong with it?
