This is not a bug in X. If at all it's a kernel bug. I'll write a mail to the kernel ML and see what they say. Maybe even the kernel can't fix it and it's just my BIOS that's broken...
In the meantime a workaround is documented here: https://bugs.freedesktop.org/show_bug.cgi?id=15360 I'll also attach the script I use as a workaround. ** Attachment added: "Script to run at boot fixing my specific MTRR issue" http://launchpadlibrarian.net/13330029/fix-mtrrs.sh -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
