Re: [Linuxwacom-discuss] Wacom Intuos S Bluetooth (partly solved)

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi Anna,

First I want to say that the Linux Wacom team has recently put a lot
of effort into forward compatibility in the kernel through the use of
HID Descriptors. That's why when you plug in your device via USB it
should work without any driver updates. In the past any new device
would necessitate a driver update. I realize that's of little
consolation to you. Unfortunately, Bluetooth support here is more
complicated for a couple of reasons and that's why you need to update
your driver.

To my knowledge this is the first time someone has asked for a support
with installing on a secure boot system. A google search shows only 1
similar question to yours, asked in the past few days[1]. Maybe Jason
or Ping remembers this type of request before? Anways, please bear
with us as we get up to speed on this issue.

The 'sbsign' command is only necessary for signing a kernel (not a
module) so you wont need that here. I believe, after finding a system
to test on, that the trouble you're experiencing is that the signed
driver isn't installing. Running through the process, I get the
following errors during the "sudo make install" step of installation:

depmod: ERROR: failed to load symbols from
/lib/modules/4.15.0-22-generic/extra/wacom.ko: Exec format error
/usr/sbin/update-initramfs -u -k 4.15.0-22-generic
update-initramfs: Generating /boot/initrd.img-4.15.0-22-generic
modinfo: ERROR: could not get modinfo from 'wacom': Exec format error
depmod: ERROR: failed to load symbols from
/var/tmp/mkinitramfs_dkPWtS/lib/modules/4.15.0-22-generic/extra/wacom.ko:
Exec format error

Also, running 'modinfo wacom | grep version' after the failed
installation returns the error:

modinfo: ERROR: could not get modinfo from 'wacom': Exec format error

Can you confirm for me that you are having the same errors and seeing
the same issue?

Best,
Aaron
