Hi you out there,

i've got the following problem:

running F20, the alps touchpad on my new Lenovo Z510 is recognized as a PS2 mouse.

dmesg output is "psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b6 06", so it should be this known kernel-bug: https://github.com/he1per/psmouse-dkms-alpsv7 .

Following the instructions, the install script fails with error: "Error! echo Your kernel headers for kernel 3.13.5-200.fc20.x86_64 cannot be found at /lib/modules/3.13.5-200.fc20.x86_64/build or /lib/modules/3.13.5-200.fc20.x86_64/source"

What do i have to do to get my touchpad working?

Thank you very much in advance for your helpful answers!

kernel headers are missing. The instructions at https://github.com/he1per/psmouse-dkms-alpsv7 do not mention building any custom kernel. You may need to get rid of incomplete kernel installation, then yum -y install dkms; yum -y update kernel*; reboot then follow the psmouse-dkms-alpsv7 instructions.

thank you. i'm not very experienced in this , i usually don't dare to modify the kernel. How do i get rid of the incomplete kernel? remove with yum? what else? thanks again

Your original title suggested you have built a custom kernel, but if not then there is probably nothing to worry about. What is the output of uname -r; rpm -q kernel; rpm -qf /lib/modules/3.13.5-200.fc20.x86_64/build?

i thought i built a new kernel following the instructions on github.

output is

3.13.5-200.fc20.x86_64 kernel-3.11.10-301.fc20.x86_64 kernel-3.13.5-200.fc20.x86_64 kernel-3.13.5-202.fc20.x86_64 kernel-3.13.5-200.fc20.x86_64

i'm running the3.13.5.200 because under 3.13.5.202 my wireless didn't work.

psmouse-dkms-alpsv7 does not build a new kernel. If /lib/modules/3.13.5-200.fc20.x86_64/build is present then exactly which command results in "Error! echo Your kernel headers for kernel 3.13.5-200.fc20.x86_64 cannot be found at /lib/modules/3.13.5-200.fc20.x86_64/build or /lib/modules/3.13.5-200.fc20.x86_64/source"?
