I was hoping you could help me.

I have a AMD A6 CPU/GPU with Radeon 6530 HD integrated graphics and 8 GB ram. Whenever I boot to a live desktop with the live CD (ubuntu or xubuntu flavors) my display stops working - the monitor stops getting a signal from the PC.

I have tried various boot settings from the 'tab menu' on the CD - nomodeset, xforcevesa, lga=771, and none of them do the trick.

I tried a fedora live CD and it works, so I know I just need to feed it the right settings.

Can anyone help? Thanks!
