laptop keyboard and mouse not working after update

killnine · 2012-01-21 22:32:33

Hello

Yesterday I performed an update. While doing so I had to become more familiar with signed keys, and I implemented a key, the configuration, and successfully updated after a while, with

 pacman -Syu

I used the system the rest of the day and all was well, but after putting the system down yesterday and bringing it up today I am not able to use my laptop's keyboard and mouse anymore. I can connect a usb keyboard & mouse and they will work for only a bit and then I must restart the system after they stop responding.

I really do not know what I am looking for while researching. Does anybody have an idea they would share with me please?

The laptop is a Dell XPS 15z

The problem in this thread seems potentially relevant:

Thank you for the link.

It seems it could possibly be a module issue, and maybe an /etc/modprobe.conf issue.

I booted back to arch, with a USB keyboard and mouse attached, and when I started x my desktop appeared, but I could not perform any action. I could not get anything to open, the clock did not load, it just sat there.

So I rebooted, connected to the network and started looking around. I had a modprobe.conf and grep-ing lsmod for usb or cpu yielded no results.

I then performed another -Syu and was warned that kmod and mod-init-tools were in conflict. I continued and let it update.

Now after update there is no /etc/modprobe.conf, but there is a new rc.local.pacnew.

Do I need to get a modprobe.conf back? and if so how?

And what should I do with the new rc.local??

Thank you for any help

Yes, you do need modprobe.conf: http://www.archlinux.org/news/kmod-repl … nit-tools/ How to get it back I don't know, though.

You should merge rc.local.pacnew into your (probably modified) rc.local. I use EMACS' ediff mode, vi has an utility for this, too. Try

diff /etc/rc.local /etc/rc.local.pacnew

to see if there is any vital difference.

thank you, as far as kmod, to the man pages it is

but as for rc.local, the new rc.local.pacnew looks almost exactly the same except my personal data is missing from it. I am trying to figure out the advantage of filling in the blank one to replace the full one....
