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: .

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 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 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"?
