add uinput module to kernel

[tckosvic]

I am trying to implement copy/paste from host openSUSE to guest Gentoo VM. I have installed spice-vdagent on the host and the guest. vdagent will not start on the Gentoo guest as error messages say "uinput" kernel module is needed to start vdagent.

Cannot find detailed instructions needed to install uinput either as builtin to kernel or as a separate accessible module.

Any advice?

As a novice with configuring kernels, how do I enable INPUT_UINPUT in my Gentoo kernel configuration. Do I use "make menuconfig"? Where in kernel structure do I find INPUT_UINPUT enable option?

thanks, tom kosvic

Yes, make menuconfig. Then, press / to start a search by Kconfig symbol. Write INPUT_UINPUT, then hit Enter to submit the search. You will get some number of matches, probably only one since this is a fairly specific search. Press the number key corresponding to your desired match, which probably means pressing 1. This will jump you to that option. Enable it via Y or M, as usual. Save and exit. Rebuild the kernel.

great info. vdagent now starting. copy/paste to gentoo vm now working.

I compile new kernels. What make kernel config option, e.g., make olddefconfig do I use to keep this change in-place in the future.
