Description
I have New Vegas (installed through steam), it's been running fine since its install half a year ago.

I was playing a save yesterday, and after a couple of hours I encountered something that seemed like a memory problem (glitchy, shaky movement, clipping issues), which led to a CTD after several minutes. I tried playing again today, and on passing the intro screens, I had no mouse cursor, and seemingly no keyboard input.

Edit: I was able to get into one of my saves using the arrow keys (should have thought of that). I have no mouse input in game period, or keyboard input (aside from dpad and return)

Edit 2 Going into the settings, there are no mouse or keyboard options period. Time for a complete reinstall of the game 🙁 – the ESC key works for skipping the intro sequence, but no further.

Steps Taken

  • Restarted PC, jiggled the cable
  • I had an older catalyst driver, I updated to the latest beta (don't think this matters though)
  • Verified the integrity of the game cache
  • Deleted and allowed the game to re-create the .ini settings
  • Searched for 3 or 4 pages and found no similar issues

Best Answer

Welp. My logitech controller driver changed in some way, or some kind of .ini thing happened, and new vegas decided to prefer it preferentially over everything. I saw controller mappings in the settings menu, unplugged it, and got mouse/keyboard input back. Plugging the controller in again cause the game to point out an option to disable 360 controllers, which I never paid attention to because I don't have a 360 controller (yeah yeah, 360 mode), and because this has never been an issue. I was about to reinstall when I noticed the button mappings in settings.

Thanks for your input VascovdEng and Wojtek. Sorry if I wasted anyone's time, hopefully anyone else with this issue will see this.
