From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8) Gecko/20051216 Fedora/1.5-3 Firefox/1.5 Description of problem: After recent "yum update", 3D graphics stopped to work with depth 16bpp. Previous update was done more or less one week ago and then everything worked just fine. Version-Release number of selected component (if applicable): xorg-x11-drv-sis-0.8.1-1 How reproducible: Always Steps to Reproduce: 1. compile attached program and try running it. 2. 3. Actual Results: freeglut (./surf3d): ERROR: Internal error <Visual with necessary capabilities not found> in function fgOpenWindow X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 4 (X_DestroyWindow) Resource id in failed request: 0x0 Serial number of failed request: 16 Current serial number in output stream: 19 Expected Results: The program should show up the window. Additional info:
I do not seem to be able to attach any file but it does ot matter. The problem appears with depth 24bpp as well.
Other OpenGL programs say eg.: spartan/builder error: unable to find visual to support double buffer, RGB, Z-buffered rendering.
I have only now noticed some stuff in the log file: No matching visual for __GLcontextMode with visual class = 1 (32774), nplanes = 4294967295 No matching visual for __GLcontextMode with visual class = 1 (32774), nplanes = 4294967295 No matching visual for __GLcontextMode with visual class = 1 (32774), nplanes = 4294967295 No matching visual for __GLcontextMode with visual class = 1 (32774), nplanes = 4294967295 Looks pretty bogus to me. There was a similar report on dri-devel list.
This problem seems to be getting reported on various hardware, rather than just SiS. I've also noticed that it is only getting reported on x86_64. Adding to FC5Target tracker. If you discover any additional info or mail postings, please add them to the report.
Not sure if this is relevant but warnings (not critical errors, fortunately) about lacking visuals can be seen on other hardware too. My 4years old Xeon with Matrox G550 and xorg-x11-6.8.2-1.FC3.45.2 prints following whenever I execute an OpenGL program: $ ./datavisualiser > log libGL warning: 3D driver claims to not support visual 0x23 libGL warning: 3D driver claims to not support visual 0x24 libGL warning: 3D driver claims to not support visual 0x27 libGL warning: 3D driver claims to not support visual 0x28 libGL warning: 3D driver claims to not support visual 0x2b libGL warning: 3D driver claims to not support visual 0x2c libGL warning: 3D driver claims to not support visual 0x2f libGL warning: 3D driver claims to not support visual 0x30 I wonder whether the fatal error I see with FC5devel is just the visual removal pushed one step further.
