[Qgis-user] Poor performance on Toshiba Laptop

[acarvajales at fcien.edu.uy]

First of all, thanks for such a complete and quick response, Alex.

Secondly, the repositories are those suggested at qgis.org:

deb     http://qgis.org/debian natty main
deb-src http://qgis.org/debian natty main

Whether or not the nature of the shape i'm trying to work with is what  
undermines my possibilities of running QGIS normally enough, i'm  
afraid i have no way of giving you that info right away.

The file, as i understand, can (in fact) be used by the general  
public, so i'll try to sort out some way of gettin' it to the web.

Finally, yes, i have tried other shapes (lighter ones, of course) and  
it performs beautifully.

Any other thoughts are welcomed, so thanks again...

With regards,

Andrés.
