Backtrack 4 on a dell mini 10V netbook
If you made some search on this topic then there are so many Linux user and specially running after installation of backtrack and commonly happened on Dell netbook or laptops. I am still in confusion that it is actually the issue of hardware or software issue or related to the compatibility of both . I managed to fix this by getting rid of my Ubuntu installation and installing BT4 only using my live CD. Seems to work fine for me now.
If you are able to do like this then you should try to go for this and I am sure it would also be helpful for you !!!!!!!!
