This problem is also found in 7.2.1511

I suggest you ask Dell about the linux driver for your laptop.

Another thing you could try is to test-install ELRepo's kernel-ml. This is to find out if the latest kernel from kernel.org has support for your device.

installed elrepo-ml kernel but it did not fix the touchpad not detected issue:

kernel-ml-4.11.2-1.el7.elrepo.x86_64 Tue 23 May 2017 10:43:46 AM CDT

Sounds as if your best (or only) option is to ask Dell...


TrevorH (developer)

Do you have the xorg-x11-drv-evdev xorg-x11-drv-synaptics xorg-x11-drv-wacom packages installed?


huatun (reporter)

My apology the latest kernel 4.11.2-1.el7.elrepo.x86_64 fixed it. The kernel package installation provided another boot option which I overlooked.

(to answer your previous question, all 3 drivers were installed)


huatun (reporter)

However the latest kernel cause the WiFi not to work. So, I am booting up with 3.10; and will be without touchpad for now. Thank you @TrevorH for your assistance.


huatun (reporter)

thank you toracat for your assistance as well.
