Hi, I also want to confirm bug. In my case this is Radeon HD 8750M with hybrid intel 4000 (sandy bridge) on Samsung notebook.
What new information I found: - after removing and purge all *fglrx*, reboot and try to install binary driver from amd I receive "No supported adapters detected" in beggining of installation. - same driver on Linux Mint Debian edition was working(!) (fglrx-drvier as well binary) My suspicios are: - new incompatibile kernel (3.16) - new "X" libraries - new fglrx driver (?) today I will try to downgrade kernel, and try if that didn't help I will look for older amd/ati binary driver.
