steev 2020-10-02 20:32 manager ~0015366	There should be a fix for this coming - can you rm the win-kex.log file and do again? This seems to stem from running kex seamless as root, and root owning the log file, so when you try to run it as a normal user, it can't write to the log.

pavangr 2020-10-03 06:33 reporter ~0015367	Tried removing the log files, this time it ran without any errors, however, nothing appeared on the desktop. No Xfce desktop bar for seamless usage. Even tried starting a program from console and received error "Error: no DISPLAY environment variable specified". when is the fix arriving? any planned dates?

steev 2021-10-25 13:58 manager ~0015376	Are you using an Nvidia GPU on that system? We've seen some issues running Firefox and Nvidia GPUs but we aren't sure where the issue is exactly.
