with the new NOP 3.01r2 (in it now) being set up for compiz, will we be seeing a new wobble? aka WNOP?

Hope so

@Mycology: Your wNOPdump looks fine, so I'm not really sure what's wrong. Could you describe again in more detail the problem you're having - possibly a screenshot too? Also do you know what these options --

[Mycology]

@tombh I deleted Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
in my xorg.conf file.
First nothing changed, I thought.
But maybe compiz is stable now. I
did not "lose compiz" while open or
close windows / applications / run programs .

I did not get "autostart compiz" runnning with xinitrc ...
any advice?

[tombh]

@Mycology: Hope you're Compiz-Fusion continues to run stable. So about autostarting -- the best way is to open /root/.xinitrc in mousepad and edit this bit...

[Mycology]

@tombh THX for your support
I did an edit of xinitrc like you described.
when puppy starts, nothing has changed. compiz is not active.
If I try to start it manual with SKIP_CHECKS....I get an error message which is attached.
???

Greetings and again TTTTHHHXXX a LOTTTTTTT

@Mycology: You forgot the attachment! So you can't get Compiz-Fusion to work at all now? Have you thought about starting all over with a fresh live-CD boot of wNOP and installing kirk's ATI-fglrx dotpet from scratch? I know that might be a lot of work, but it would be good to know the exact steps you go through to get wobbliness -- whether it autostarts or not. Oh yeah, did you try the Xfce autostart application I mentioned?

@floborg: Thanks for the wNOPdump -- I've been able to isolate the problem:

@floborg: Well we're definitely getting somewhere. The reduction of resolution and bit depth certainly solved the memory problem but as I suspected DRI (hardware accelerated graphics) failed because of the missing module. After installing my dotpet the relevant modules became available and were loaded, the Xorg log reported a lot more success. This is really so very close The error reported is this:

[Mycology]

hi,
I got that message and from then on compiz never started again.
Maybe I try a fresh install of wNOP next weekend - or is there a chance to rescue my system?

@Mycology: Googling your errors I see that people are having similar problems especially caused with Radeon 9700 cards (others too though), some have reported success with

Hi floborg,

Bad news I'm afraid, it appears that your card just won't run Compiz-Fusion
It's because of this non-power-of-two support. From what I can gather graphics cards have to do a lot of maths and so try and take advantage of mathematical quirks -- such as square surface areas (ie power-of-two) being easier to manipulate. So non-power-of-two support probably refers to cards powerful enough to manipulate any sized surface areas, anyway your card and the mach64 driver don't do non-power-of-two maths.

This has led me to rethink my setup for wNOP, removing unneeded drivers and including detection and notification of unsupported cards. So at least I know where the bottom lines are now.

Thankyou very much for all your work, we pushed all the way to the limits and found a wall But at least we know it's there now!

PS. You don't have to do this but just out of interest what does

Seasons Greetings,

Yesterday I had the opportunity to use a laptop that had a new enough ATI card to use the fglrx driver -- this has been the one remaining area that wNOP has failed in. I managed to install the driver and get Compiz-Fusion 'working' -- it wasn't pretty.

The point is, that in order for Compiz-Fusion to talk to its graphics card (whoever the manufacturer), one of two technologies must be running, either AIGLX or XGL. From the beginning I decided to work with AIGLX, as Puppy 3 comes with it already working perfectly. The problem is though, that ATI has only just began programming their drivers to support AIGLX! Pooh Of course, we are not restricted to running ATI cards with ATI drivers, there is also the open source radeon driver, which has, somewhat ironically, supported AIGLX for ages and in most cases outperforms the ATI drivers. However, and this is the problem, the radeon driver does not support the more recent ATI cards. So a tricky situation.

Now, my primary aim for wNOP is that it supports all the graphics cards that are capable of running Compiz-Fusion. As far as I know there is no other LiveCD distro that is able to do this 'out of the box'. I haven't tried Austrumi yet, partly because of the language barrier but also because I find it hard to believe that it does what wNOP aims to do but in 67MB! Anyway, whether wNOP is the first or not, I feel it is a very realistic goal and something that a lot of people would appreciate. Both that Puppy is such a staggering feat of innovation and that Compiz-Fusion is such an enjoyable and original way of using a desktop -- an awesome combination in my opinion.

So I was just on the verge of releasing wNOP2, I had the ISO ready and everything, but now, after seeing fglrx and AIGLX in action for myself, I feel it would be best to change direction away from AIGLX and towards XGL. This is unfortunate for reasons other than extra work (not that I mind the learning experience!) -- (1) that AIGLX is really the more advanced and complete technology (2) that ATI will be working to improve support for AIGLX, but who knows how long that might take.

I have no experience with XGL nor recompiling Xorg, so it looks like it will be a fair amount of work. I don't know enough yet but maybe it is possible to have AIGLX and XGL on one system? That'd be perfect. So, I'll see how it goes, I think it would be good if I released what I have done as wNOP1.1

Okay, hope you all get great Christmas presents,
tom
