Actually, last week I was kinda very frustrated at not being able to run SC2 on Slackware64 and as I had an unused partition at my HDD I decided installing Ubuntu x86_64 10.10 and SC2 installed beautifully. I love Slackware, but fair's fair!
Anyway, since I had my /home on a different partition accessible to both OS (OK, both are Linux after all, but the packaging differs a lot!) I boted Slackware this morning and I wondered what would happen if I just decided to try and run SC2... I was very happy finding it works flawlessly!
