RHEL 6.5 no longer recognizing keyboard or mouse
 

Just as the title states, it's a Dell server that was working fine until several days ago. One of my users logged out of a VNC session instead of just closing the window, which prompted a need to login locally so that VNC sessions would work again. When I went to login, the keyboard and mouse don't respond at all. Tried restarting and I can get into the bios just fine and the caps lock and num lock keys light up when pressed right up until the three red bars at the bottom are loading (I'm assuming this is when the GUI is loading). When I arrive at the login screen, I can see the cursor momentarily and then it's gone. If a caps lock / num lock was on before this, then the light remains on on the keyboard (so it's getting power) and the light is on the mouse as well. I can unplug and plug them back in and it remembers the device (ie the lit num lock is still lit).

Legacy USB is turned on in the BIOS. HALDAEMON seems to be running and healthy (I can stop and start it with no errors). LSUSB shows the devices properly and when I unplug them they are removed from the list and reappear when I plug them back in. I have also tried plugging them into the USB ports on the front and back of the server with no change.

I can SSH into the box and my remote apps (Rstudio mainly) work properly. I can't VNC into the box because it's at the login screen, so I can't get a GUI at all, but I can run any other diagnostic things you need from a command line if that's helpful at all. I have tried running various scripts I found online to reset the device list both with them plugged in and with them unplugged.

Also note that up until a couple of weeks ago, these devices were working fine on this box. I have already tried replacing the keyboard and mouse with others (and these both work on other computers).

Any ideas? Thank you.

What distro are you running? Also, what's the output of:

Not sure how I would tell what distro it is... isn't that RHEL? Red Hat Enterprise Linux? 6.5. Sorry, if you need some other info please let me know how to get it. Thought including the RHEL in the subject was all that was needed. thanks for your response, command and output below.

Your X11 installation needs to be updated because evdev is out of date. Since you are using Redhat, you need to go through RH support.
