Ubuntu – Patching kernel for graphics tablet, not sure if it’ll work

driversgraphics-tabletkernelpatch

I just got a new graphics tablet that seems to be supported in kernel 3.11, found this: https://patchwork.kernel.org/patch/2624521/

I downloaded the new kernel deb packages from here http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy/ and installed them but apparently nVidia doesn't have drivers for 3.11 yet (nor 3.10) so I had to revert back to 3.8.

Now my question is, can I just follow instructions here https://help.ubuntu.com/community/Kernel/Compile, and apply that patch to my current kernel in Ubuntu 13.04 or is there any other way I can get this working with no headaches?

From https://wiki.ubuntu.com/Kernel/MainlineBuilds

The mainline kernels builds are produced for debugging purposes and therefore come with no support. Use them at your own risk.

The kernels are supplied "as is" with no guarantee that it will work, less so with a patch.

Have you ever compiled a kernel before ?

If not, see: http://bodhizazen.com/Tutorials/kernel

You can post back if you get errors or problems, but again support may be limited at best.

Ubuntu – Patched kernel, everything works except the device Huion 580 that was supposed to work with the patch

I finally got it working. First download kernel 3.9.10, extract and apply patch:

> cd linux-3.9.10
> yes "" | make oldconfig
> patch -p1 < ../path/to/huion.patch
> make oldconfig
  Huion tablets (HID_HUION) [N/m/?] m
> fakeroot make-kpkg -j 4 --initrd --append-to-version=elclanrs kernel-image kernel-headers
  ...

After that I installed the packaged debs, rebooted and everything works now, uname -a reports custom kernel.

Finally I had to restrict the tablet to only one monitor, the right one in this case. My setup is (1920+2560)x1440:

xinput set-prop "HUION 580" --type=float "Coordinate Transformation Matrix" 0.5714 0 0.4285 0 1 0 0 0 1

Here are the patched kernel debs for Ubuntu 13.04 64bit:

Ubuntu – Followup question: How to get fix for trackpad bug from 3.15 kernel

To answer your questions: At the bottom of the patch page you linked it says that the patch is present in 3.15. Kernel version 3.15 has been released, and version 3.16 will be the default kernel in Utopic Unicorn. If you want to install kernel 3.15 in Ubuntu 14.04, download the appropriate packages (what are they?) from the mainline kernel PPA or install them using apt and ppa technology, which I recommend, because then you keep your kernel updated. Be aware that other issues may come up when you install a newer kernel.
