Using my fixed packaging (which properly loads the shader files)... https://bugzilla.redhat.com/show_bug.cgi?id=705144 pymol reports... Detected OpenGL version 2.0 or greater. Shaders available. Detected GLSL version 1.20. OpenGL graphics engine: GL_VENDOR: X.Org R300 Project GL_RENDERER: Gallium 0.4 on ATI RV380 GL_VERSION: 2.1 Mesa 7.11-devel FYI, this shader support works find on Radeon hardware with pymol 1.4 and glew 1.3.8 on MacPorts and fink using Xquartz so this is a definitely a defect in the mesa-dri support and associated ati video drivers on linux. Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), and * output of the dmesg command, to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance. Created attachment 500091 [details]

Where is the mesa-dri-drivers-experimental packages for Fedora 15? In Fedora 14, I had to use those for this Radeon X600 graphics chipset (although the 3D acceleration was still horrible... as evaluated with the Representations demo in pymol). its all in mesa-dri-drivers now. Kernel panics still occur with 7.11-0.14.20110621.0.fc15 mesa packaging set. Kernel panics are still present in current Fedora 16 TC builds. I should also note that the X600 graphics chipset exhibits artifacts in the plymouth graphics boot screen, during the diagonal fill of the circular logo. The logo fills about a quarter of the way and then the screen turns into a set of interlaced lines which gradually change shade. Eventually the desktop appears and the screen artifacts disappear but this suggests many bugs currently exist in the radeon driver. Also, interestingly, when Fedora 16 is restarted, the diagonal fill Fedora logo graphic is properly rendered, So the graphical artifact from Commment 8 only occurs on startup. This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
Created attachment 499374 [details] x,org log from Dell Latitude D810 running Fedora 15/i386 RC3 Description of problem: When Fedora 15/i386 RC3 is installed on a Dell Latitude D810 with Radeon X600 graphics, the machine kernel panics if the pymol program is run and its demos started. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Install Fedora 15/i386 RC3 on a Dell Latitude D810 2. Install pymol 3. Launch pymol and select the representations demo menu item. Actual results: I expected the pymol representations demo to be displayed. Expected results: The molecules of the pymol representations demo appears in the center of the pymol window but the demo freezes and a few moments later the machine kernel panics. Not good. The linux OpenGL driver support may simply be too bug to support the new glew based shader support safely. Additional info:
