Hello all,
I'm on Linux Kubuntu for a bit over a year now and I soon also got MediaCenter34 (version 35 by now) for playing my music. Since recently, however, on my notebook the MediaCenter UI does not show up. I see the processes, but it's completely hidden. I even did a fresh install of Linux just now (now Kubuntu 26.04 LTS clean install) but the problem came back at once.
Two more interesting things: When I delete the ~/.jriver folder, holding all the program settings (including license information), I can start the program and I do see the "enter license / continue trial / etc." dialog. When I reactivate my license, the UI won't show up again.
The other odd: On my "big" PC there is no problem. It has a slightly older NVIDIA graphics card and the OS once has been a Ubuntu 24.04 LTS, has then been migrated to become a Kubuntu and I at least upgraded it to versions 25.04, 25.10 and now 26.04 LTS, so it's a much less clean installation I suppose.
Does anyone have any idea how to get MediaCenter work properly on the notebook again?
