yeah but if it still is giving issues it might need rework flux

sorry about that but we seem to have an issue with the new chameleon and nvram module for the icloud and facetime fix. it seems to affect some of the "D" series like the Dx20's
you probably need to load the BT driver from dell on windows so it upgrades and activates the firmware. the blue nub on the keyboard does not work with defaul trackpad option but there are other choices in edp you can choose from.
yeah i am experiencing the same thing on a d620 nvidia and lion. looks like my permissions are screwed so far as i can tell. but got my snow running but i am booting with a usb drive with chameleon and an extra folder with a -f -v from snow i was not able to even get into the lion volume because of permissions. so had to set it manually using propedit app then running a permissions fix for 2 hours... it is currently still running. that lion partition was also where chameleon boot file resides since it is my first partition on the drive.
you might just have a bad dvd drive on your machine.... it is a known problem. try cleaning the lens. but usually it's a bad ribbon to the laser pickup of the drive.
did you try the bootpacl Dell Latitude D830, Intel x3100 graphics card (1920x1200 model) that should be for high resolution screen you might have to edit the org.chameleon.Boot.plist and put your proper resolution.
