Frankie, you are running a newer kernel than OP, I think you have different issues. At some point (Linux v3.13-10103-g205e221, will end up in 3.14 and newer), AMPDU was disabled for iwldvm devices...

Frankie, you are running a newer kernel than OP, I think you have different issues. At some point (Linux v3.13-10103-g205e221, will end up in 3.14 and newer), AMPDU was disabled for iwldvm devices...
Good point Bucky, the K800 has a USB connection... but that one is only used for charging the keyboard (there are no external batteries). All communication is done with the tiny USB receiver that...
netgooroo, The k800 keyboard works here without issues. Are you sure that the device is paired? If not, try https://lekensteyn.nl/logitech-unifying.html#ltunify. The kernel that is loaded for this...
nouveau is blacklisted when you have nvidia installed. In order to use nouveau, either uninstall nvidia or edit /etc/modprobe.d/nvidia-current_hybrid.conf (exacty name may differ, but it ends with...
See https://github.com/amonakov/primus for a description of primus. It will indeed be usable with the nvidia blob, although it is not exactly PRIME.
Bumblebee starts an X server on its own and...
You do not need them, PRIME support for libxrandr is already upstreamed in 1.4.
When trying PRIME, you **must** disable bumblebeed since optirun will not cooperate with PRIME:

Having support from default repositories in 12.10 is too optimistic, maybe 13.04. Maybe a PPA will become available during 12.10. See also...
Copying without using redirection can also be done with:
cp /var/log/Xorg.0.log xorg.0.log
Unless you change the current working directory (which can be shown by executing the "pwd" command,...
To fix the xkb issue, install "libxkbfile-dev" (may be necessary before building X).
You also need to rebuild the evdev module (and any other X module you use, e.g. the "xf86-input-wacom" module for...
Mesa is just one patch. Clone from git://anongit.freedesktop.org/mesa/mesa and apply this patch on it (I'm using the master branch, but 8.x.x should be fine too).
Something to keep in mind: when...
Thank you for your suggestions, I have updated the description at https://launchpad.net/~lekensteyn/+archive/wacom-tablet.
Since no known issues have been reported for 0.13.0, I've uploaded a new package for Precise that supports the Intuos5 device. The precise xserver-xorg-input-wacom 0.14.0 package already supports...
Stopping a service require adminstrative (root) privileges. To stop a service, use something like sudo stop cups. I suggest not to randomly turn services off. The most power can be saved by disabling...
1) Would be a good idea.
2) Lenovo IdeaPad Z570 seems to be an Optimus laptop
3) no experience.
I would not recommend noacpi, it likely increases power usage even more and has other side...
Try upgrading to Precise for updated drivers.

You need to re-login (or reboot). See http://askubuntu.com/q/36930/6969
It sounds like you've installed a mismatching nvidia driver. Can you add your /var/log/Xorg.8.log and the tail of your kernel log (/var/log/kern.log)?
I've just updated the Oneiric PPA for Cintiq 24HD support. As kernel 3.2 in Ubuntu Precise does not have support for this, I'll copy it for Precise as well.
The package for Oneiric is awaiting...
Citation needed for "battery drainage" on Bumblebee or Ironhide. The latest Bumblebee version (3.0 as of this writing) uses a kernel module for reliably toggling the power on nvidia Optimus cards.
...
Remove the nvidia-current package or install Bumblebee (see previous link) to fix resolution issues.
Have a look at http://askubuntu.com/q/36930/6969. You most likely have a /etc/X11/xorg.conf file present that should be removed. Reboot after doing so.
Since the kernel in Precise (3.2.0-15) still does not provide support for the 3rd gen tablets, I've copied the packages from Oneiric which works for me.
Even if you do not need to use the nvidia card, Bumblebee still has added advantages: it disabled the nvidia card to save power. It looks like the Optimus settings are disabled (in BIOS?)
Since...
You can open a run dialog and type the optirun command in, nothing fancy ;) The other way is to run optirun detached like this:

There are two common methods which can be detected on most machines. The only machines that currently do not work are the Lenovo Y470 and Y570 due to Lenovo's retardness. GPU switching is currently...
