I'm trying to create an ubuntu .deb package for the (pretty awesome) Io Language. I am not the developer of that language, so I'm not familiar with its sourcecode yet. This is my first attempt at creating a .deb file.

In order to create the .deb, I'm following these instructions:

http://www.webupd8.org/2010/01/how-to-create-deb-package-ubuntu-debian.html

So far I've been able to create a .deb file (io_2010.06.01-1_amd64.deb) and a changes file (io_201.06.01-1_amd64.changes). I'm using lintian to check the changes file, and it reports an issue I don't know how to resolve:

$ lintian -Ivi io_2010.06.01-1_amd64.changes

... (lots of messages)

I: io: no-symbols-control-file usr/lib/libiovmall.so
I: io: no-symbols-control-file usr/lib/libgarbagecollector.so
I: io: no-symbols-control-file usr/lib/libbasekit.so
E: io: postinst-must-call-ldconfig usr/lib/libiovmall.so

I've read the debian manual 8.8 section. I think I understand what the problem is (I need to make sure that ldconfig is invoked "somewhere", possibly on a place called "posinst") but I don't know how to resolve it (i.e. where this "posinsts" file is and how should I change it).

The current way of installing Io in Ubuntu is basically running sudo make install and then sudo ldconfig. Maybe the makefile should be modified so ldconfig is called from it? I don't know.

Thanks a lot.

I'm trying to remove a ~40 seconds pause that happens when my Ubuntu machine starts.

During this pause, all I see is a magenta rectangle (approx 80% of screen size) over a black background.

The gap is clearly visible on my bootchart (not using an IMG tag here because the image is too high):

I also see a gap on my syslog. It seems to be related with the "video device" (I've got an NVIDIA).

What can I do to fix this? It didn't happen on Ubuntu 10.10.

I've done some more tests. It seems that the boot sequence requires some sort of input while booting (?) It turns out that it'll not boot until I press enter (the magenta rectangle stays in the screen forever unless you press enter)

Any ideas? Thanks!

When my computer goes to console mode (booting up, shutting down or Ctrl + Alt + F1)), the text is super big. I can't take a screenshot of it, but it looks like a 640 x 480 resolution. My monitor normally works at 1440 x 900.

I remember that the console text that appeared while installing from the CD was nice and small.

How can I make the console text look like it looked while booting from the CD?
