### Controller Setup

See attached pdf manual for details.

# Software

# Xorg AMDGPU

I own a AMD Vega64 and an using it with i3 on Manjaro. The misaligned monitors on the greeter and the manual resolution and refresh rate switching were super annoying. 

# Setup

* Updated Manjaro with kernel >5.0 including amdgpu kernel driver 
* AMD Vega64
* Monitor capable of 144Hz and Freesync
* Second Monitor not capable of those things

# 144Hz modline

This was relative simple, amdgpu is pretty verbose on startup and prints *all* available modlines for the connected outputs on the card into `/var/log/Xorg.0.log`.
With a simple `less /var/log/Xorg.0.log` I quickly found it somehwere along with 
```
[     6.454] (II) AMDGPU(0): Printing probed modes for output DisplayPort-2
[     6.454] (II) AMDGPU(0): Modeline "2560x1440"x60.0  241.50  2560 2608 2640 2720  1440 1443 1448 1481 +hsync -vsync (88.8 kHz eP)
[     6.454] (II) AMDGPU(0): Modeline "2560x1440"x143.9  586.00  2560 2568 2600 2640  1440 1465 1473 1543 +hsync -vsync (222.0 kHz e)
[     6.454] (II) AMDGPU(0): Modeline "2560x1440"x119.9  482.64  2560 2568 2600 2640  1440 1447 1455 1525 +hsync -vsync (182.8 kHz e)
[     6.454] (II) AMDGPU(0): Modeline "2560x1440"x99.9  398.23  2560 2568 2600 2640  1440 1496 1504 1510 +hsync -vsync (150.8 kHz e)
```
and used the one with my desired configuration. 

# xorg config 

To get my setup working as expecting without manual configuration on every startup, I needed to place a persistent config in the xorg config folder so e.g. `/etc/X11/xorg.conf.d/10-monitors.conf`. 
There, I configured both my GPU driver and the monitors like following. 

The *Monitor* sections are straightforward.
*DisplayPort-2* is my 144Hz display, so I added the modline as a new preset `2560x1440_full` and used it in the *PreferredMode* option. 
Further I enabled DPMS, the *Display Power Management Signaling* so the system could turn of the Montiors just in case. 

The *Device* section contains the preferred options for the given GPU drive, in my case *amdgpu*. 
I enabled *TearFree* as well as *VariableRefresh*, the first one should reduce tearing on both displays while the latter one enables FreeSync on my 144Hz monitor. 
After a reboot, my monitor indeed reported it was using FreeSync!

## Fixing multiple rust-analyzer running

https://github.com/LazyVim/LazyVim/discussions/3825#discussioncomment-9937797

in ~/.config/nvim/lua/plugins add a file called mason.lua with content
```lua
return {
  {
    "neovim/nvim-lspconfig",
    opts = {
      setup = {
        rust_analyzer = function()
          return true
        end,
      },
    },
  },
}
```

## Removing unwanted Markdown warnings

in ~/.config/nvim/lua/plugins add a file lint.lua
```lua
return {
  {
    "mfussenegger/nvim-lint",
    opts = {
      linters = {
        markdownlint = {
          args = { "--disable", "MD013", "--disable", "MD012", "--" },
        },
      },
    },
  },
}
```

## Add prefered hidden file viewing

in ~/.config/nvim/lua/plugins add a file neo-tree.lua
```lua
return {
  "nvim-neo-tree/neo-tree.nvim",
  opts = {
    filesystem = {
      filtered_items = {
        visible = false,
        show_hidden_count = true,
        hide_dotfiles = false,
        hide_gitignored = false,
        hide_by_name = {
          -- ".git",
          -- '.DS_Store',
          -- 'thumbs.db',
        },
        never_show = {
          ".git",
        },
      },
    },
  },
```

## Add prefered color scheme

in ~/.config/nvim/lua/plugins add colorscheme.lua
```lua
return {
  -- add gruvbox
  { "catppuccin/nvim" },

  -- Configure LazyVim to load gruvbox
  {
    "LazyVim/LazyVim",
    opts = {
      colorscheme = "catppuccin",
    },
  },
}
```
