Final test: kernel 2.6.34-rc5 + stock drivers + proposed X server update. X server uptime: approximately 1 hour.

After reaching ~300MB in object bytes, the computer began to slow down due to excessive I/O and disk swapping, so applications were slower to load and respond; however, in periods of calm I/O activity, graphics performance is absolutely fine. I see no graphical slowdown whatsoever! To summarise: Kernel 2.6.32-21-generic + proposed X server from this bug report = memory leak, graphical slowdown Kernel 2.6.32-21-generic + xorg-edgers packages = memory leak, graphical slowdown Kernel 2.6.34-rc5 + proposed X server from this bug report = memory leak, no discernible graphical slowdown Kernel 2.6.34-rc5 + xorg-edgers package = memory leak, no discernible graphical slowdown In other words: a) I get a memory leak in all cases, with or without the patched X server; b) the newer kernel eliminates any graphical performance impact from the memory leak. I'm not sure in what direction to proceed; since it seems that most people are seeing the bug fixed, perhaps this is a separate leak that's not related to 03_fedora_glx_versioning.diff and 04_fedora_glx14-swrast.diff. Shall I file a new bug, and if so, against what component? -- [KMS] gem objects not deallocated https://bugs.launchpad.net/bugs/565981 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
