I have fedora 19 installed and running on my Dell Lattitude E6430. Yum told me the other day that there were updates available. So I let yum update everything.

After updating and rebooting, the keyboard was gone! I can remote ssh to laptop. Gnome and KDE both show same behavior.

Comparing the error from xorg log below (Failed to load /usr/lib64/xorg/modules/input/evdev_drv.so) and the yum log, /var/log/yum.log has this entry
Apr 08 05:25:34 Updated: 1:xorg-x11-drv-evdev-1.0.0.5-5.0.2.el5.x86_64

I wonder if this is where things went bad. If so, I'm going to have to figure out how to undo this or repair it. Anyone have advice on this?

Some info:

Thanks!

First thing I would do is boot to a Live CD of something other than Fedora and verify that the keyboard is, indeed, functional. If it is, it is definitely a problem with your software load; if it isn't, the keyboard may well have failed.

If the keyboard has indeed failed, no amount of mucking about with software will fix it.

Never overlook the obvious, I know right? Keyboard works fine in the circumstance you mention. How do you roll back a library to a previous version? Is that the best thing to try now?
Thanks,
Dave

check the logs there will/should be a list of what was updated/changed/modified. you should be able to track that. also with F19 you should be prompted at boot to choose the kernel version you wish to start. choose the last working kernel and run from there. also file a bug report with fedora. F19 will be going out of support in a few months, but still not bad to tell them hey you broke something.

Unfortunately it makes no difference the kernel version I boot into: no keyboard. It's an X11 problem, isn't it, not kernel. I need to figure out, I think, how to recreate X11.

I was able to solve the problem finally.

Did this:
yum downgrade xorg-x11-drv-evdev.x86_64

which resulted in
this version: xorg-x11-drv-evdev-1.0.0.5-5.0.2.el5.x86_64
going to
this one: 1:xorg-x11-drv-evdev-1.0.0.5-5.0.1.el5.x86_64

However, still keyboard not working. So I tried the downgrade one more time, which resulted in
this version: 1:xorg-x11-drv-evdev-1.0.0.5-5.0.1.el5.x86_64
going to
this one: xorg-x11-drv-evdev-2.8.1-2.fc19.x86_64

Keyboard works, and I'm happy once again.

Thanks for all the advice.
Dave
