G'day lixo1. There seems to be a conflict in the information you have supplied. Can you please confirm whether you are using the open-source xserver-xorg-video-ati driver or the ATI Catalyst driver downloaded from the ATI website?
Note that even when using the Catalyst driver it is best to obtain it from the Ubuntu repositories in case some build fixes or compatability fixes have been added - for Natty this will be essential until ATI releases an updated driver as they have provided Ubuntu with a prerelease version of their driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/651590 Title: ATI Radeon HD 5850 blank screen during boot -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
