Курсор в терминале не переходит на новую строку

Manjaro 23.1.2
В эмуляторе терминала, когда вводишь команды, курсор доходит до конца строки и, вместо того чтобы перейти на новую строчку, возвращается в начало этой же строки, запечатывая уже введенные символы. Последующие строки того же ввода (до enter) уже спускаются нормально.
Это не только в Konsole, но во всех. Тачпада нет (у меня десктоп), проблема появилась недавно, вроде никак обновлений к тому моменту не производилось. Такое ощущение, что происходит возврат каретки, а перехода на новую сроку не происходит. В настройках консоли смотрел - ничего криминального не вижу. В чем может быть проблема? Замучился уже.
Еще обратил внимание, что длина строки, хотя и зависит от ширины окна консоли, но строка полностью до края не доходит.

Переведено на русский:

In the terminal emulator, when entering commands, the cursor reaches the end of the line, and instead of moving to a new line, it returns to the beginning of the same line, overwriting the characters already entered. Subsequent lines of input (before hitting enter) descend normally. This happens not only in Konsole but in all terminals. I don’t have a touchpad (I’m using a desktop), and the problem appeared recently; as far as I remember, there were no updates by that time. It feels like a carriage return is happening, but the line break isn’t occurring. I’ve checked the console settings - I don’t see anything criminal there. What could be the problem? I’m already fed up with it. Also, I’ve noticed that the length of the line, although it depends on the width of the console window, doesn’t extend all the way to the edge.

Welcome to the Forum!

It might be that your prompt isn’t configured correctly.

Can you post the content of your ~/.bashrc file?

cat ~/.bashrc

Your prompt in ~/.bashrc looks OK, you seem to be using the default options.

Something else is misconfigured, no idea what that might be.
