Public bug reported:
Binary package hint: yelp
When upgrading from Interpid to Jaunty I discovered that graphics performance
had degraded.
Flash and movie playing performance was very poor even with the xv output
driver.
when looking at the /proc/mtrr I noticed that there was no line listed
for my Nvidia Geforce FX5200 card as there was in Interpid.
looking at /var/log/debug in Jaunty it reads:
Sep 23 20:02:56 ubuntu kernel: [ 101.521701] mtrr: no MTRR for
e8000000,8000000 found
I have tried both with 2.6.27-7 and 2.6.28-15 kernels on Jaunty and I'm
currently using 2.6.27-14 on Interpid so this seems to be more of an X
server problem than kernel bug. (Shouldn't the X server set the mtrr
range?). Switching from the nv driver to the proprietary Nvidia driver
on Interpid removes the mtrr entry as well.
