| Summary | [r600g] glXCreateContextAttribsARB() fails under certain circumstances |
| Severity | normal |
| Classification | Unclassified |
| OS | Linux (All) |
| Reporter | nfxjfg@gmail.com |
| Hardware | Other |
| Status | NEW |
| Version | 9.0 |
| Component | Drivers/DRI/Radeon |
| Product | Mesa |
Test program: http://sprunge.us/eGJa Failing output: http://bpaste.net/show/58701/ Successfull output (on another setup): http://dpaste.com/832706/ What seems to trigger this is calling glXCreateContextAttribsARB() with the following context attributes included: GLX_CONTEXT_PROFILE_MASK_ARB, GLX_CONTEXT_CORE_PROFILE_BIT_ARB, and GLX_CONTEXT_FLAGS_ARB, GLX_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB. Removing these seems to make it work. The test program has been confirmed to work on Mesa with i965, and nvidia binary drivers 304.60. The actual program which triggered this also works on fglrx. User's glxinfo: http://bpaste.net/show/58678/ X server: "x11-base/xorg-server-1.13.0-r1" on Gentoo The test program is a modified version of http://www.opengl.org/wiki/Tutorial:_OpenGL_3.0_Context_Creation_(GLX) It's not clear whether this is a bug or just a caveat, and it has been confirmed on one installation only so far.
