touchpad of laptop not working after installing fedora
 

I recently installed fedora 25 on my compaq presario 510 laptop. I was using ubuntu previously. after installing fedora successfully when I started my laptop the touchpad was not working ( which was previously working well in ubuntu) so I uninstalled it and reinstalled ubuntu. I want to try out fedora so anyone can suggest me solution please?

it is impossible to troubleshoot now that you re-installed ubuntu.
well, you could give us the output offedora is using a setup quite different from ubuntu, i think it even uses wayland as the default gui (and not Xorg as it has been for decades).

how old is that laptop?
fedora is a bleeding edge distro and doesn't really make any sense on matured hardware.
that's just asking for trouble.

the laptop is around 8 years old with intel core 2 duo processor

First, get Fedora 27 - F25 is old (by Fedora standards).
Next, Fedora has some quirks - the "tap for click" generally doesn't work until you are logged in; use the buttons if you have them. Look under settings for enabling the touchpad, and options (edge scroll, whatever).

Typically I have found that you need synaptic or libinput driver support. I would start there when searching for a solution.

** edit - added libinput **

fedora simply isn't the right distro for that gear.
stick with ubuntu LTS, or better even Xubuntu or Lubuntu. always LTS.
might also want to try some dedicated old hardware distros.

Runs on a Pentium 4 just fine - and with an *old* Radeon card. Slow, but runs.
Fedora is a lot more compliant than it is given credit for.

^ ok i was a little off-handed and dismissive.
i didn't mean fedora cannot run on old hardware, but i meant: what is the point of running an outdated version of a bleeding (!painful!) edge distro on outdated hardware.

if the intention is to use the hardware, i recommend something else.
