Hi all,
This post comes from an old thread named as "Scratch 1.4 on squeak-vm 4.10". I renamed this topic to be more clear regarding what the problem is.
After followed suggestions by the list on the previous thread, I realize that the problem isn't on Scratch, instead could be on the squeak-vm.
I did a test, using squeak-vm 4.10 with Squeak3.9a.from3.0.image, when go to full-screen ON and then switch to OFF, the Squeak is hangs and the windows turned white.
To figure out whats is happening, at this point, i have (i think so) two options to following researching:
1) Execute the fullscreen ON-OFF from Workspace.
I found that full-screen ON-OFF is performed by ScreenController class and fullScreenOff and fullScreenOn methods. How I should call this class from Workspace ?
I tried something like:
ScreenController initialize fullScreenOn
And an exception was arised.
2) This option could be hardest, i guess. Download squeak-vm source, add debug code on sqUnix11.c and debug it.
I would like to start from option 1, that seems like effortless.
Some another suggestion ?
Thanks in advance.
Gustavo.

Eek!
I am seeing exactly the same problem with Squeak 4.5, and it is happening with both Cog and the standard interpreter VM.
I am using a laptop running Ubuntu. It's hard to believe that nobody would have noticed this before, so maybe it is specific to the hardware or graphics drivers.
Gustavo, thanks for bringing this up, and sorry for not paying attention to your earlier posts. There is certainly a problem here, and it is not related to Scratch. It also does not seem to be related to any specific version of the VM. So I'm not sure what is going on here.
Who else is seeing this problem, and on what platform and VM?
Open Squeak, use the full-screen icon on the upper right to put it into full screen mode, click it again to go back. The result for me is a white screen and no further response from the image.

No Eeks!, flurps, oopsies, fscks or oy's here.
Full screen works just dandy with dual monitors. Platform is a workstation, NVidia GEForce, Slackware Linux.

Hi,
Overview ========
I would like make a brief overview of the situation.
In my case, this problem is happening on laptos Magalahes model MG3, these kind of the machines are manufactured by a Portuguese company, http://www.jp-ik.com/, focuses on provide laptop for children.
Here in Uruguay there is a country wide Educational Project, called "Plan Ceibal"[1] [2]. Thousand of these machines were distributed to children on the schools around all the country.
Until last year 2013, this machines comes with Ubnutu 10.04 installed and Squeak was working like a charm.
Currently a migration to Ubuntu 12.04 is on deployment stage, and some of the remaining issues is this (Squeak).
More info about the HW of this Machine [3]
Research results so far: ==========================
I tried get more information, calling fullScreenON and Off from Worksapce unsessfully, same behavior happened, but no additional data were printed out.
Now, I will take the another approach, related with a comment did by Tim Rowledge on the old thread.
<< "I’d say that strongly suggests a problem in the code setting the screen mode; you’ll find it (for unix) in platforms/unix/vm-display- X11/sqUnixX11.c at the function display_ioSetFullScreen(sqInt fullScreen). Since it works on many unices and has for a long time I imagine it means some problem with the specific machine’s display driver code. That could be all sorts of fun to solve. At the very least you’ll need to find an X expert, which is not me."
Taking in account, i have never developed on Squeak, my plan would be like:
1) Add debugging cide like "printf" to sqUnix11.c to may debug, and check if there where the problem
2) Compile Squeak - VM from sourece code, modified.
3) Run Squeak vm with clean Squeak image.
4) See the output of debugging code.
5) With these new clues, i'll ask help to a X expert.
What do you think, that sounds reasonable ?
Is another easier approach ?
Thanks in advance.

Hi Gustavo,
The problem with full screen on/off looks like it may be caused by the X11 window manager in Ubuntu, and I do not know how long it may take to resolve this in the Squeak VM or in Ubuntu. I see from your explanation here that the problem may be affecting children in the Plan Ceibal project already, so it would be good to find a solution soon.
I think that I have found a workaround for the problem that may help. I am attaching a change set that you can file in to a Squeak image, either the Squeak 3.9 image that you mentioned, or any other recent Squeak 4.5 image. This change uses one of the plugins in the squeak-vm package on Ubuntu, and it will force a reconnection to the X11 display after the Squeak window returns from full screen mode.
Can you please try loading this change set into Squeak, and testing it on an MG3 laptop with Ubuntu 12.04?
I have not tested this yet with Scratch, but if it works on Squeak with Ubuntu 12.04, then it will probably work with Scratch also.
This is not a real solution to the problem, but if it works on the laptops for Plan Ciebal then maybe it will help until we are able to fix the real problem.
Thanks,
Dave

Hi David,
I applied the change set with Scratch, and the problem remains, it is strange right ?
Any way, as workaround we are going to change the Window Manager from Compiz to Metacity on these machines. Using Metacity as Window Manager this problem is resolved.
Thanks a lot for your workaround, and I agree with you that the definitve solution should be done on Squeak-vm.
Regards,
Gustavo.

Hi Gustavo,
Thanks for the update. I am glad that you were able to switch window managers as a workaround.
I added an entry to our Squeak bug tracker so we will not lose sight of the problem:

Thanks Karl !! I could call fullScreenOn and Off from workspace and same behavior happened, with the only difference that after switching off the display turned up black not white.
But, sadly, this test doesn't gave me more information, no return error debugging information was printed out.
I have to take another approach to find out, what is happening.

Folks,
Could those of you who have tested this, with either good or bad results, please let me know:
1. which window manager (and version of it) your distribution is using; and
2. what your hardware native screen size is (run 'dpyinfo' and look for root window size).
If I can reproduce this then I can probably fix it.
Thanks!

To figure out whats is happening, at this point, i have (i think so) two options to following researching:
Execute the fullscreen ON-OFF from Workspace.
I found that full-screen ON-OFF is performed by ScreenController class and fullScreenOff and fullScreenOn methods. How I should call this class from Workspace ?
I tried something like:
ScreenController initialize fullScreenOn
And an exception was arised.
This option could be hardest, i guess. Download squeak-vm source, add debug code on sqUnix11.c and debug it.
I would like to start from option 1, that seems like effortless.
Some another suggestion ?
Thanks in advance.

Trying to find out the information asked by Ian, I realized that, on the same machine,
1) In Gnome we are using Compiz as window manager 2) In Sugar we are using Metacity as window manager.
And as i know that in Sugar Squeak is working fine, and in Ubuntu not. I changed the window manager on Ubuntu and voila !!, fullscreen on - off start working like a charm.
So we could strongly affirm, that the problem is an incompatibility with Compiz and this HW.
Regards.

Please, let me know if you need more information.
Thanks in advance.

Folks,
Could those of you who have tested this, with either good or bad results, please let me know:
- which window manager (and version of it) your distribution is
using; and
- what your hardware native screen size is (run 'dpyinfo' and look
for root window size).
If I can reproduce this then I can probably fix it.
Thanks!
Regards, Ian

Hi Ian,
I have a desktop computer running KDE on SuSE. Native screen size is 1280x1024. On this machine, full screen on/off works normally.
If I log on to this same SuSE machine with Gnome, this also works normally.
If I reboot the same machine into Ubuntu 12.04 LTS with Unity window manager, I see the problem as described by Gustavo.
I also have a laptop with Ubuntu 13.10 and Unity window manager. Native screen size is 1920x1080. This machine also produces the problem as described by Gustavo.
So the problem does not seem to be associated with hardware or screen resolution. It does seem to happen on Ubuntu with Unity, and on at least two different (recent) versions of Ubuntu/Unity.
My SuSE system is rather old, so the KDE and Gnome that I tested are also old. The Ubuntu/Unity systems that I tested are of much more recent vintage.
