Thanks @dino99. I've seen a lot of different suggestions for tackling this error, so it would be good to understand exactly which config change is the critical one.
I think this is a major bug on a newly installed system. As an Ubuntu Desktop user I shouldn't be experiencing an issue where the OS stops me from launching any new app once I have a few apps open. I shouldn't need to go hunting through logs to and start googling for a solution, then modify open file limits, just to run a handful of desktop applications. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1771329 Title: Can't open apps due to Too many open files Status in dbus package in Ubuntu: New Bug description: Occasionally I find that I can't launch a new terminal, or can't achieve some other desktop task.
