I have correctly installed SC2 on kubuntu 11.10, pretty everything goes right but the texture.
I get screens like this ones: http://imageshack.us/photo/my-images/835/schermata5a.png/

Any suggestion?
I had the same problem, I have a 64-bit laptop running Fedora 18. The solution was to install a 32-bit texture compression library, which on my distro was as simple as:
yum install libtxc_dxtn.i686
I hope this helps.
