"Unfortunately I have been unable to test this for a while now. I'm using the radeonhd driver on a Radeon HD 3870, which doesn't (yet) support 3d acceleration. Even back when I was using the ATI binary blob, it didn't work; the last time I started HL2 on my desktop in Linux was when I had my last NVIDIA card."
