I had this happen on a similar vintage PC, but it only affected GRUB (once booted, keyboard worked). It turned out to be USB Keyboard/Mouse support in the BIOS was off, but since yours has no PS/2 ports I doubt this the problem. Still I would check the BIOS setting for USB and see if there is a "legacy" setting. However if keyboard was working before the update then it most likely is something in the update. If you have openssh enabled you could try SSHing into it from another system, but it sounds like you have only one working system (I don't think I could survive without at least 2 so I can find out how to fix things when one breaks, or I shoot myself in the foot with some creative config change :>) ). You could try poking around from a live CD/USB, at least getting access to Google from there to look for solutions. This sounds like a good reason to stay away from .10 Ubuntu releases and stick to LTS versions. I have also found wired keyboards/mice are less problematic than wireless on Linux.
I did a quick look at the Ubuntu community wiki and some people fix this issue by removing "fwupd": sudo apt remove fwupd But you have to get logged in to do that... Contact me off list if you need other options.

I can start the machine & use the USB keyboard to access the BIOS but when it comes to the login area I cannot type anything. As well, USB mouse doesn't work. I have tried the following (and likely a few more things as well): * Different keyboards & mice * Different USB ports * No PS/2 ports so could not check that. * Moved hard drive to different chassis. * Reset/change BIOS settings * Restarted multiple times * Tried accessing command line All of this still gets me back to the same spot. It was recent build (likely at 17.10 as I kept up with updates) & was done from scratch (likely started as a 17.04 but can't be sure). I am pretty sure it is the OS based on swapping the hard drive, but not sure how to fix it. With the limited browsing access (via phone) I couldn't find much that pointed me in the right direction. I know there was an issue recently with some lenovo devices, but that doesn't seem to apply here. I am at the point now where I will try to spin up a USB drive to at least try to access the data on the desktop, but would like to get it running again with out having to format & start again; because the massive pain in the arse that installing applications, setting up emails, etc. I am not sure if it is possible to run updates (that will likely fix the issue) on the installed system from a Live USB or not. Any ideas would be welcome. _______________________________________________ clug-talk mailing list clug-talk@clug.ca http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying _______________________________________________ clug-talk mailing list clug-talk@clug.ca http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
