I have Ubuntu 11.10 on my notebook PC. Is it anything to do with the plugins? I tried running it with squeak -plugins /usr/lib/scratch/Plugins -vm-sound-pulse /usr/lib/scratch/Scratch.image and it gave the output:

Code:

nathan@nathan-Compaq-Presario-CQ61-Notebook-PC:~$ squeak -plugins /usr/lib/scratch/Plugins -vm-sound-pulse /usr/lib/scratch/Scratch.image
found gettext in path
/home/nathan
could not find display driver vm-display-X11; either:
  - check that /usr/lib/squeak/4.4.7-2357/vm-display-X11.so exists, or
  - use the '-plugins <path>' option to tell me where it is, or
  - remove DISPLAY from your environment.
/usr/bin/squeak: line 277:  3651 Aborted                 $VM "$1" "$2"

Thanks for looking into this!

Ah - yes, if you use the VM from the repositories, then it has its own plugin location, different from Scratch's.

For testing purposes, it's probably easiest to copy  CameraPlugin, UnicodePlugin, and ScratchPlugin from /usr/lib/scratch into the Squeak package's plugins directory (will be unique for each version you test with).  Then make the -plugins path point to the Squeak VM's plugin directory. That way it'll use its own X11 plugin.

Is it possible for scratch to search for the OS and thus find the necessary location?

Or search for the VM version? and work out where the files are
Or we could write up a small script that copys the files from the VM plugins to the scratch plugins?

I'll get my uncle to help.  He's the one who put ubuntu on my computer (which I love now!)

Wait there will be a squeak version of scratch 2.0?

No, he's our only Squeak Dev. But he's also our main editor developer (it's in Flash). And he has his hands full with that.

Edit - oops, posted before I read the whole thread, and didn't see the post above this one. Thanks for clarifying, Lucario!

my point is, maybe the new plugin is the problem?

It's possible, but I think the issue you were running into was caused by the fact that the old scratch launcher script only specified one location for plugins. So you either need to make sure all the plugins are in one place, or figure out how to specify two locations to look for plugins (which I think is possible, but i'm not sure how.)

I typed "sudo nautilus" then typed my password and stuff, then I copied the Scratch plugins into /usr/lib/squeak and it is still giving me the same error. 

Ah - I think the squeak vm plugins are in a different directory than that - a directory specific to the version number. On my system ( Ubuntu 12.04 ), they're in here:

/usr/lib/squeak/4.4.7-2357
(The plugins all start with so. )

You could also try this user script for starting Scratch - it should set things up correctly.
http://www.assembla.com/code/scratchonlinux/subversion/nodes/trunk/scratch/src/scratch?rev=92

Oh yes, I forgot to the the version number. Silly me. 

I managed to set things up to reproduce the error that Miry is finding, on the debian bug. ( http://bugs.debian.org/471927 )
The startup script is executing squeak as follows (nathanpricks - you can probably just use this command instead of the startup script, if the squeak versions are right.)

/usr/lib/squeak/4.4.7-2357/squeakvm -encoding UTF-8 -vm-display-x11 -xshm -plugins /usr/lib/scratch/Plugins/:/usr/lib/squeak/4.4.7-2357/ -vm-sound-pulse /usr/lib/scratch/Scratch.image

I can't download 12.04... I will have to get it from a magazine cover disc lol.

  12.04 is an LTS release (Long Term Support), so it should be a very polished, well tested release....

*someday*
....

So far, it really isn't so great - I'm seeing some nasty glitches, more than I'd bargained for (screen blanking out after sleep, that kind of thing). So I'd wait a while before installing it.

Is it possible to make the start up command have a list of folders to check?

Yep! - that's what the colon between plugin paths in this startup command is doing:

/usr/lib/squeak/4.4.7-2357/squeakvm -encoding UTF-8 -vm-display-x11 -xshm -plugins /usr/lib/scratch/Plugins/:/usr/lib/squeak/4.4.7-2357/ -vm-sound-pulse /usr/lib/scratch/Scratch.image

does it help?

Could this article help? It explains how to allocate more memory to the squeak vm and by the looks of that log, it is an out of memory error you are having. Although whether that is one of the problems that scratch is experiencing I do not know.

As we recently announced, we've made Scratch 1.4 available under the Gnu Public License v2.

This was done in part to make it easier for Linux distros like Debian, Ubuntu, and Fedora to integrate scratch into their repositories, so it's easy for their users to install. Our previous license was the major roadblock - but now that the licensing issue is resolved, there's one last major hurdle that we need your help to get over. Scratch no longer works with later versions of the Squeak Virtual Machine (VM). 

In the current Linux version of Scratch, we bundle our own (old) VM in the package, but this isn't really the cleanest way to do it - it's better if Scratch depends on the VM package from the distro's repository. But people are getting blank screens when running Scratch on later VMs. Here's what Miriam Ruiz, an awesome super helpful Debian contributor who has been working on packaging Scratch, says:

«It works for me with squeak-vm 4.0.3.2202 (squeeze) but when trying to
run it on squeak-vm 4.4.7 (wheezy) I just get a blank screen. According to
jredrejo, the modification causing this problem might be
related to the changes made to the squeak-vm to be able to run it with
composite managers and compiz.»

My plans are mostly getting a diff between the last VM that works and
the current and start applying patch after patch until it doesn't. I
just have to find a couple of spare hours to do it (I've been totally
overloaded at work the last weeks).

JohnM, our only Squeak developer, is swamped working on Scratch 2.0 and doesn't have time to dive into this. And the rest of us are focused on various things related to 2.0 as well.

Can AT help solve this problem, and figure out what must be done to make Scratch work with later versions of the Squeak VM? (Whether it's changes to the Scratch image, or the VM) It would make it much easier for thousands of free software users to install Scratch. We could really use the help.

The most up to date info about the packaging of Scratch for Debian is here:
http://bugs.debian.org/471927

Thanks for reading!

but since scratch is for linux, those ARE linux distros, so that means they are compatible heres what im saying
           ↑→ Debian
LINUX→ Fedora
           ↓→ Ubuntu

it's really not needed for it to do that because if its a linux ditro, and if scratch was made for linux, then its not needed

yeah that looks more like a memory error (caused by it being a new vm i don't know)

well, how i see it, it's infinite recursion. and no, it didn't help
