@mitu When I did use 20.04, there was an issue with the nvidia 390 driver installing. I thought rolling it back would somehow be better for compatibility. I do have dolphin installed with retropie on my laptop, so I believe I will just use clonezilla to clone it to the nvidia build, and sort through the driver issue then. If that doesnt work I will switch away from Lubuntu and try another distro.
So, you get the same results on fresh install...And just spit balling per say, how many video ports do you have? Additionally, have you tried any other displays? My thoughts would be the next thing to look at the communications via HDMI (Assuming you are using HDMI based on the hardware). I would use a known/good HDMI cable, attempted another port, and another display is possible.
@mitu This help request can be closed out. I ended up uninstalling retropie and Ubuntu and put Batocera on my SSD. Batocera seems to be more user friendly in terms of initial installation and settings. From what I've read Retropie has more options/settings but my emulation needs are simple and Batocera serves me well.
You're not running into issues with building the N64 emulator mupen64plus? It's only happening on Debian Stretch (x86-64) but it could be my setup so that's why I'm asking. It's requiring a newer version of cmake than what's available:
/home/pi/RetroPie-Setup/tmp/build/mupen64plus/GLideN64/projects/cmake /home/pi/RetroPie-Setup/tmp/build/mupen64plus /home/pi/RetroPie-Setup
CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
CMake 3.9 or higher is required. You are running version 3.7.2
Awesome! I set up open box to start with 1280x720, verified it via the log, and it worked perfectly with the threading set false. Looks way better than it did set true, has better response/less lag, and of course the screensaver doesn't kill it after 10 minutes.
