I have Ubuntu 12.10 installation in Virtualbox. Sometimes anything using pager (less, man) just acts funny and seem to fail to "trap" keys, ie. scrolling, searching etc does not work. Instead control keys are just printed
^C^W etc. Even CTRL-C, CTRL-D etc do not work and only way to escape is CTRL-Z.
I never do anything special to break it and it also seems to fix itself after time. Rebooting usually does not fix the issue, but for example, it has fixed itself after idling over night. That makes no sense :-)
How to fix permanently or how to workaround/reset it?
- Same issue occurred on a Windows PuTTY ssh connection to openSUSE server. It is therefore not related to VirtualBox nor strictly limited to Ubuntu.
