--- Comment #5 from herminio.hernandezjr@gmail.com --- I noticed in the 11.0.3 release notes that this issue was fix. However I am running Lubuntu 16.04 (development) on my iBook G4 and I am still. Getting the same issue. When I change to Defaul Depth 16 I get 3D acceleration. I ran strace under both conditions and am post them plus my Xorg.0.log
