Hello everyone,
I'm currently using my old windows computer to post, because I've caused a boot process issue on my ubuntu 18.04 computer. The problem started when I was trying to figure out how to remap my right control key (which I use often but was broken) onto my right alt key. I had read online that people recommended editing the xkb file to remap keys. After I edited the lines concerning control and alt, I restarted my computer and found that the boot process froze at the line "Started Hold until boot finishes up". I left it on overnight thinking it might finish, but nothing changed.
I also tried restarting a few times, as well as using the grub menu options like repair and clean, but nothing helped. Lastly I tried some of the solutions from other topics with similar problems, but they didn't help either. One of the solutions was to remove snapd, which I did but that just made the boot process list longer.
I have access to the recovery mode, grub menu and F2/F3, but I'm new to linux so I don't know any troubleshooting commands that can help. If I caused this issue by messing with the xkb file, does anyone know any terminal commands to revert the file to its original script? I know windows had a recovery option to revert the system back to an earlier state (which I had used when I messed around with the registry and broke stuff on my win 7). Does ubuntu have any option or command that can do something similar? Attached below is the screen that my computer freezes on.
Thank you all very much for your time and any advice you can offer me to fix this issue. I will try to reply as soon as I can to any questions posted; though I might be delayed due to my job.
