MTRR allocation failed. Reason for lagging mouse?
- Anmelden oder Registrieren um Kommentare zu schreiben
Hello,
a few days ago I found that my mouse was clearly lagging now and then. Beside of this, my system seems to be quite stable and performance is not bad at all.
In my syslog I found:
[kernel] [ 0.768728] [drm] MTRR allocation failed. Graphics performance may suffer.
And of course I thought that maybe this could be the issue.
I'm using xmonad at the moment. Sure I seldomly use the mouse, but maybe my graphics performance is limited and I just don't feel it at the moment.
Any ideas?
Some additional info:
During boot, I get the following message:

I also forgot to give you the lspci info about my graphic card:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Any ideas are appreciated!
What kernel are you on? (uname -r)
If you have not tried it yet, install more recent version of the kernel (version 3.11) and of the graphical stack:
$ sudo apt-get install --install-recommends linux-generic-lts-saucy xserver-xorg-lts-saucy
You may not like the "--install-recommends" option. If so, independently install "libgl1-mesa-glx-lts-saucy" (which is recommended by "xserver-xorg-lts-saucy") too.
If that does not solve your issue, you can try the latest version of the kernel: https://trisquel.info/en/wiki/update-linux-libre-kernel
Thank you both. After upgrading the kernel, nothing really changed.
I then installed debian wheezy and still have the allocation error, but my mouse isn't lagging anymore.
I don't have any clue why this is the case.
Maybe wheezy is using an *older* kernel version and some kind of bug appears only in newer kernels?
I don't know.
So if someone encounter the same problem: try out various kernel versions, also older ones.
If you wish to see how deep that rabbit hole is, these guys probably could help https://01.org/linuxgraphics/
