Installig SM5 on MK9 Hardware with GeForce 4800 GS (LINUX) (In Progress)

I used Kyzentun's guide


I first installed Linux Dependencies as Kyzentun
---------------------------------------------------------------

sudo apt-get install libxrandr-dev libgl1-mesa-dev libgl1-mesa-dev libpng12-dev libjpeg62-dev zlib1g-dev libogg-dev libvorbis-dev libmad0-dev libavcodec-dev libavformat-dev libtheora-dev libasound2-dev libgtk2.0-dev libswscale-dev libglu1-mesa libglu1-mesa-dev libbz2-dev libglew1.6-dev libva-dev cmake gcc g++ mesa-common-dev libx11-dev libxtst-dev libjpeg8-dev libc6-dev yasm libasound-dev libpulse-dev libjack-dev lame alsa liblua5.1-0-dev nasm libpcre3-dev linux-libc-dev

sudo apt-get install linux-headers-$(uname -r)

sudo apt-get update

Here we start with Kyzentun's guide
sudo apt-get install build-essential
sudo apt-get install git
git clone --depth=1 https://github.com/stepmania/stepmania.git
cd stepmania
git submodule init
git submodule update
cd Build/
cmake -G 'Unix Makefiles' -DWITH_FFMPEG_JOBS=1 -DCMAKE_BUILD_TYPE=Release .. && cmake .. //Here kyzentun told me to change -DWITH_FFMPEG_JOBS=4 to 1
make -j1 //this parameter is different too, originally was set to 8
#!/bin/bash
cd ~/stepmania
./stepmania


At this point, Stepmania is functional, but it was giving me 30 FPS, so I installed nvidia's drivers
-------------------nvidia-------------------------------
sudo apt-get update
sudo apt-get install nvidia-current
---then reboot
sudo nvidia-xconfig
nvidia-settings

Here I changed the OpenGL Settings to High performance
and I unmarked the options Sync to Vblank and Allow Flipping

-----------------Stepmania----------------------------
Then I went to stepmania and changed some parameters

Graphic Options

Display Mode: Full Screen
Display resolution: 800x600
Aspect ratio: 16:9
Brightness: 80%
Texture Resolution: 1024
Refresh Rate: Default
Wait fo Vsync: Yes

Now, it gives me 65 FPS in gameplay, even using videos.

So, now I have a little problem, some songs are unzynchronized, the songs are fine, I checked them in my laptop. I'm stuck in this point, I hope someone can help me with this problem.
I'll be updating this post...

Thanks to Kyzentun for the support.

Post one of the simfiles you're having problems with. Maybe it's an engine bug.

This is one with that problem...

I probe it on stepmania v5.0 beta 1a
and the steps are fine.

Is there something I can do? or I will have to quit trying?

The sma loader was never finished or maintained, so that's why it's not playing that song right.

Is there any way to configure stepmania v5.0 beta 1 on linux with video support?
