Xorg.log

The touchpad on DNS 0801480 notebook (PEGATRON C15B) doesn't work. Also it is not detected by the hwinfo program. The same issue is reproducible with all tested kernels including 3.14.25 and 3.14.33.

Please see attached xorg.log and output of hwinfo.

Does booting with i8042.noloop=1 help?
Comment 4 Andrey Ponomarenko 2015-02-26 09:40:36 UTC
Yes, this option has fixed the issue.

See updated Xorg.log, dmesg and hwinfo.

patch trying to solve the pegatron problem

Hi Andrey Ponomarenko,

would you mind trying the attached patch and then boot the new kernel without any i8042 parameters? If this works correctly, you can use your touchpad out of the box in the newer kernels.

Thanks!
