With NoAccel, you're not using dri. Only the mesa version which you've compiled your xorg server against thus matters (if you've compiled your xorg server from git, I've seen a couple versions which broke indirect rendering completely, these things do happen). Moving to mesa/glx, though maybe it should rather be xorg/lib/glx. does not happen when AGP is set to 4x in the xorg.conf (In reply to comment #8) > does not happen when AGP is set to 4x in the xorg.conf Have you removed the NoAccel line? I fail to see how that AGP line can make any difference without Accel enabled. Please don't mix different issues.

Also, please attach a log file from starting the X server without Option "AGPMode".

So I asked him to provide mesa packages built with no gcc optimizations and the problem went away. I also tested mesa built with -O1, which were almost OK - glxgears running, 3d games running, but I got an X.org freeze when resizing a window in jedit. *** This bug has been marked as a duplicate of bug 11380 *** It's not exactly the same as bug 11380, since even building with -O1 triggers the crash here. There must be some additional problem, but I can't tell yet if it comes from mesa or from gcc. Definitely not the same as 11380 because 11380 doesn't crash the X server -- it just garbles the output. Do you still have this issue with more recent mesa ? Mass version move, cvs -> git 4 months with no reply from submitter. Closing. |
