your permissions on the theme folder look okey to me. And the conflict messages that you posted above for librsvg2-common and librsvg2-2, I have them too.
With these being in place, I would suspect the standard Python modules.. following libraries are imported in the python code and hence I would see these as the dependencies
All these requirements are readily packaged part of the Cairoclock. Could you please try installing it from here or from the application manager. With that we should see the SVGClock on the desktop

Addison,
Could you just try running, as root:
apt-get -f install
I think that'll resolve all the problems.

Last two times I've used that, it chucked out Xterm, Tear, and a ton of other junk to the point where I couldn't even recognize what was left on my tablet anymore.
But since I live on the edge, I went ahead anyway.
Code:
[1|root@Nokia-N800-43-7|~]apt-get -f install Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... Done The following packages will be REMOVED: osso-software-version-rx34 0 upgraded, 0 newly installed, 1 to remove and 19 not upgraded. Need to get 0B of archives. After unpacking 0B of additional disk space will be used. Do you want to continue [Y/n]? n Abort.
I remember before having to type something like "Yes, do as I say!" so at least I didn't receive that unhappy message again.
I'll follow up on Shin's suggestion and post back tomorrow.
Seriously, any of you idgits got this working or even tried to install SVGClock?
I know that I'm slightly stupid, but this has to be a new low for me.

Got it!
Cairoclock install did the trick.
So last of the newbie questioning from me.
I'm trying to load up this theme.

This is what I'm seeing in Xterm:
Any ideas to what I'm doing wrong?

Hey shin.
Okay, I guess I used the wrong command to unzip a theme file. I originally just copied your command (tar zxvf) to decompress it instead of what was required (tar xvf).
Sorry, I should have first googled before asking what was wrong.
So I'm all good here now.
Happiness!
Holy crud though dude, your clock really chunks up the tablet.
Even doing something simple like scrolling through the application menu is horribly slow now.
Oh well, it's still slick looking!
Thanks again for this, shin.
It's a solid, first release.

Addison - happy to see that it is working for you now and a very good selection of the clock face, to go with your background / theme.
As you can see in the first post of this thread, I have talked about the scope to improve performance.. Yes, there is a performance issue and I kind of know what the issue is.. Now I only hope I know how to fix it.. As I said I am a noob on the linux /Maemo platform and more so on the Python programming. I have learnt quite a bit, working on this. But dont have a clue yet on fixing the performance issue. I trying to read up on Python within the limited time I have. I hope to fix this performance issue and release it on the Extras repository, with some help from the Python gurus we have here..

Request to the Python experts here
I think I know the issue with this SVGClock performance..
Actually I am rendering all the SVG components of the clock together. Since the static components such as the background ( clock face, clock markings) and foreground ( Clock frame, Clock glass, frame) parts get rendered every time along with the moving parts such as the Minute/Hour hand, they end up consuming far too many CPU cycles, I think. This overloads device that we have on hand, making the N8x0 too slow, as reported by Addison.
I would really appreciate it, if some one can take a look at the code and help tell me how I can do some kind of buffering or pre-rendering of the above static components ( Background and Foreground parts), so that they are not read and rendered every time the second/minute hands are being refreshed. I believe this can be done within Python itself ( without worrying too much about, Cairo or rsvg)
To look at the code, pls see SVGClock.py under /usr/lib/hildon-desktop/SVGClock.py
If I get some directions on this buffering of the SVG files and pre rendering, I will be more than happy to package this with all dependencies to release it to Extras-Devel and then Extras..

Though lengthy, thought I will paste the code here for anyone interested:

If only you would have posted this a year ago.
I don't think there's too many of us N8x0 survivors left here anymore.
Well, this was the best I could find on the net, and even so, I'm not sure it's what you're looking for.

If you want, I have no problem bumping this thread forever until someone responds. *lol*

I agree with you on the N8x0 survivors.. Actually I am surprised how fast the tablet community became a minority here within a couple of months..
I joined the party late ( as you can see from my profile ), though I was lurking in these forums before deciding to jump in.. I was one of those people who thought Nokia was actually coming out with a superior 'internet tablet', as a sequel to the N810. Anyways I love my internet tablet/N810 and the various great apps the community has developed for it ( such as the Easy debian by qole, Penguinbait's boot from mmc card method, bunanson's world tv , t_moyashi's Quasar/Dillo etc - I know I am missing to mention other great apps here).
So it is this spirit of sharing that made me release this, not so complete applet to the community, created with what little knowledge I gathered with my spare time. Because I thought it would look good on your tablet!
I am hopeful that someone would help in the buffering/ pre-rendering query above ( yes the code is kind of 'messy' now), to better the clock performance and I plan to take it to Extras anyways with some clean up..
Having said that, you can see immediate performance improvement by disabling the second hand of the clock. This can be done by setting the "enable_seconds" parameter to "False" in /usr/lib/hildon-desktop/SVGClock.py, that is immediately after the 'import' section ( or cairoclock.py, if you used my original installation method):
Change this line as below to see immediate improvement in performance ( but the Seconds hand does not display any more)

Your instructions were to start off as root but it was unclear if that was still needed when I untarred the Themes file.
And yeah, it looks like everything is set up correctly on my end so there has to be a small dependency issue here that we're missing.
Well, hopefully your big brain will problem solve this stupid crud you've created.
Thanks for hanging in there with me.
