For convenience, I have copied a lot of my homedir and a lot of /etc from my aging laptop (RoseViolet) to save reconfiguration on my new box(Ebony). That's the reason why.

Here's the problem. On Ebony, Chrome bellyaches about the profile being opened by another process on another box, even mentioning RoseViolet by name. I'm using Alien Bob's chromium-ungoogled-101.<something>.

I have had a look about, done a recursive grep in ~/.cache/chromium-ungoogled & .config/chromium-ungoogled. I did do a web search, but the one page supposed to tell all is gone . Any ideas?

Sorted. It disappeared as mysteriously as it appeared. I did delete stuff before posting. Maybe a power off was required?
