How about a test screen?
It seems to me displaying certain patterns would probably
pin point things fairly quick.
The discription of the problem indicated
that white and black had different transparencies.
What about other colors?
Which bytes get mistook for alpha channel?

What form of pattern would diagnose the problem most easily?
Then is the problem the same on all linuxes or different on differnt ones?

Squeak color stuff has known bugs. Some of them hard to trace.
With a lot of integration bugs.
Many due to different authors with different assumptions.

So I imagine getting a handle on how to make it work elegantly
will take real study on someones part.

I think all of them are good ideas. Other problem I found with the screen is when I have an image saved in a 17" monitor for example, and the I open it in a 15", the screen is crap. It would be nice Squeak recognize the actual screen resolution of the pc you are running and adapt the squeak image to that resolution.

I am newbie so perhaps I am saying non sense things.

Cheers,

Mariano

I found a fix. We need to prefer a depth 24 visual over the 32 one,
which has that weird alpha problem (the window renders completely
transparent).

I am trying to run Damien's development image (sq3.10-7159dev08.06.1) using the 3.10.1 VM under Ubuntu Gutsy Gibbon. Compiz Fusion is installed.

The Squeak VM crashes to the prompt with the following:
ioSetDisplayMode(32, 134606703, 2005274256, 134596551)
ioSetDisplayMode(-32, 134606703, 2004909744, 134596551)

ioSetDisplayMode(-32, 2019438636, 2019438656, 134596551)

Does this mean something to someone? Any ideas what to fix? I should point out that I was running fine with the 3.9 VM.

Thanks for any advice.

Re: [squeak-dev] Getting Squeak3.10 to work under problem Linuxes

Is there anything in place to smoke test (at least) new releases on all (or as many as possible) platforms?

It occurs to me that a great way for the non-gurus like myself to contribute would be to "register" as said testers, making our various platforms "available" for testing and feedback prior to a release. I'm sure there is testing in place already, but you could have lists of people that get a request to "try this out," with some reasonable expectation that they do so.

Like I said, maybe this is already done.

Just a thought,

Rob

Hi Rob,
great idea. I am playing around with Linux so have at least 3 different distros running. So to me this would be a great way to contribute.
I can imagine having a wiki-like list on squeakvm.org/linux showing the different results of the different versions in the different distros. A bit like Linux on Laptops <http://www.linux-laptop.net/>
