I have a thinkpad x61t with an intel video chipset. I have installed 4G of RAM. I am running Intrepid with 64-bit kernel 2.6.27-11-generic. The Intel X driver works but cannot set the frame buffer to write combining. glxgears reports 450 FPS.
If I run mtrr-uncover (see above) and restart X, glxgears reports 650 FPS. So the problem still exists. -- MTRRs set up incorrectly with 4GB RAM -> X slow https://bugs.launchpad.net/bugs/210780 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
