Linux On My Samsung

Hi All,
I did a fresh install of Ubuntu 10.04 on a Sansung N10 and now the card reader is not recognized any more. No problems with 9.04 and 9.10. Any suggestions?
Thanks,
Nikos

SOLVED. I found under win XP that the SD Card was not formatted. Anyway this happened after I installed 10.04. Now it works fine.
