Although I understand this issue is fixed in karmic, I found that if I issue (under karmic)
cat /proc/mtrr I see the output shows that mtrr is not set up. I can fix it for my gpu card by issuing a sudo -s echo "base=0xe0000000 size=0x10000000 type=write-combining" >| /proc/mtrr If I put the echo command inside /etc/gdm/PostLogin/Default , it is ignored in karmic (wasn't in jaunty). I can make it stick by putting it in /etc/rc.local (but with the provisos noted by the posts above). With mtrr correctly setup, their is a very slight improvement in flash performance, so it appears to be doing something. I am not using an intel gpu - I have an nVidia one. My /boot/config-2.6.31-15-generic contains CONFIG_MTRR=y CONFIG_MTRR_SANITIZER=y CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=0 CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1 CONFIG_X86_PAT=y So does this mean I don't need to set up mtrr in karmic? And it is safe to ignore the wrong setup reported by cat /proc/mtrr ? -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 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
