I just bought a new Dell Inspiron 7347 for my mother. It is supported officially by Ubuntu 12.04 LTS so I guessed that Linux would go nicely on it. Well.
I installed Mint 17 KDE (based on Ubuntu 14.04 LTS), which comes with kernel 3.13.0. The wireless was not active, I had to install one of the broadcom drivers in the messy Ubuntu repo:
sudo apt-get install bcmwl-kernel-source. The package provides the
wl module which is automatically loaded: all fine. However, the touchpad also refuses to work (touchscreen works fine). I tried several kernels: all kernels >= 3.15.0 have working touchpad but non-working wireless: the
wl module is missing. Kernels < 3.15.0 have working wifi but non-working touchpad.
For now, I'm trying to keep on kernel 3.13 and fix the touchpad.
xf86-input-mtouch is installed.
I managed to track down what seems wrong with the touchpad, which by the way is correctly recognized by
xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB-PS/2 Optical Mouse id=10 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen Pen id=12 [slave pointer (2)] ⎜ ↳ ELAN Touchscreen id=13 [slave pointer (2)] ⎜ ↳ DLL0674:00 06CB:75DB id=14 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Integrated_Webcam_HD id=11 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=15 [slave keyboard (3)] ↳ Dell WMI hotkeys id=17 [slave keyboard (3)]
What's wrong is that there are too many touchpads recognized.

Also, at login KDE warns me of having found too many touchpads and that this is unsupported. Using newer kernels, this still happens but touchpad works (as stated, wireless does not).
Looking at the Archwiki, I tried setting up something like:
cat /etc/X11/xorg.conf.d/50-synaptics.conf Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event6" Option "TapButton1" "1" Option "TapButton2" "2" Option "TapButton3" "3" EndSection
event6 was gotten from:
cat /proc/bus/input/devices ... I: Bus=0011 Vendor=0002 Product=0007 Version=01b1 N: Name="SynPS/2 Synaptics TouchPad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input6 U: Uniq= H: Handlers=mouse1 event6 B: PROP=5 B: EV=b B: KEY=e520 610000 0 0 0 0 B: ABS=660800011000003 ...
However, this does not seem to work. But I guess that a xorg rule is the right path forward.
I also attach the outputs of:
(with 3.13.0 kernel)
