# Bluetooth keeps disconnecting - reconnecting
|
|
|
|
Solution: Change config in /etc/bluetooth/main.conf
|
|
`ControllerMode = bredr`
|
|
Then `sudo systemctl restart bluetooth`
|
|
|
|
UPDATE: It's still not fixed :(
|
|
Trying `yay -S pipewire wireplumber`
|
|
TODO test it again

# Touchpad scroll direction (libinput)
|
|
|
|
To change touchpad scroll direction on Arch Linux using libinput driver:
|
|
|
|
## Investigation steps:
|
|
1. Check which driver is used: `pacman -Q | grep -E "(synaptics|libinput)"`
|
|
2. Verify libinput config exists: `ls /usr/share/X11/xorg.conf.d/ | grep libinput`
|
|
|
|
## Solution for libinput:
|
|
Create `/etc/X11/xorg.conf.d/30-touchpad.conf`:
|
|
|
|
```
|
|
Section "InputClass"
|
|
Identifier "touchpad"
|
|
Driver "libinput"
|
|
MatchIsTouchpad "on"
|
|
Option "NaturalScrolling" "true"
|
|
Option "Tapping" "on"
|
|
Option "TappingDrag" "on"
|
|
Option "DisableWhileTyping" "on"
|
|
EndSection
|
|
```
|
|
|
|
Set `NaturalScrolling` to:
|
|
- `"true"` for macOS-style (natural) scrolling
|
|
- `"false"` for traditional scrolling
|
|
|
|
Restart X11 (log out/in) or reboot to apply changes.
|
|
|
|
## Alternative: Synaptics driver (legacy)
|
|
|
|
If using the older synaptics driver instead of libinput:
|
|
|
|
### Investigation steps:
|
|
1. Check for synaptics: `pacman -Q xf86-input-synaptics`
|
|
2. Look for config: `ls /usr/share/X11/xorg.conf.d/ | grep synaptics`
|
|
|
|
### Solution:
|
|
Create `/etc/X11/xorg.conf.d/70-synaptics.conf`:
|
|
|
|
```
|
|
Section "InputClass"
|
|
Identifier "touchpad"
|
|
Driver "synaptics"
|
|
MatchIsTouchpad "on"
|
|
MatchDevicePath "/dev/input/event*"
|
|
Option "VertScrollDelta" "-111"
|
|
Option "HorizScrollDelta" "-111"
|
|
Option "TapButton1" "1"
|
|
Option "TapButton2" "3"
|
|
Option "TapButton3" "2"
|
|
Option "PalmDetect" "1"
|
|
Option "SHMConfig" "on"
|
|
EndSection
|
|
```
|
|
|
|
Synaptics scroll direction options:
|
|
- `VertScrollDelta` and `HorizScrollDelta`:
|
|
- Positive values (e.g., `"111"`) for traditional scrolling
|
|
- Negative values (e.g., `"-111"`) for natural/reversed scrolling
|
|
|
|
**Note:** libinput is the modern standard. Consider switching from synaptics to libinput for better support and features.

# Theme switching issues
|
|
|
|
## Tmux and terminal not updating after theme switch
|
|
|
|
**Issue:** After running the theme switcher script, tmux sessions and existing terminals don't reflect the new theme until restarted.
|
|
|
|
**Temporary workaround:**
|
|
- Restart tmux sessions: `tmux kill-server && tmux`
|
|
- Open new terminal windows
|
|
|
|
**TODO:**
|
|
- Investigate tmux theme reload without killing sessions
|
|
- Check if terminal emulator supports theme change signals
|
|
- Improve theme script to handle live theme updates
|
|
|
|
## Tmux window names showing hostname instead of command
|
|
|
|
**Issue:** Tmux windows show "homelab" (hostname) for inactive tabs but correct command names for active tabs.
|
|
|
|
**Root cause:** Catppuccin tmux theme with `@catppuccin_window_tabs_enabled on` uses different text formatting for active vs inactive windows.
|
|
|
|
**Solution:** Disable catppuccin window tabs:
|
|
```
|
|
set -g @catppuccin_window_tabs_enabled off
|
|
```
|
|
|
|
**Alternative:** Configure explicit window text for both states:
|
|
```
|
|
set -g @catppuccin_window_default_text "#W"
|
|
set -g @catppuccin_window_current_text "#W"
|
|
```
|
|
|
|
Also ensure automatic renaming is enabled:
|
|
```
|
|
setw -g automatic-rename on
|
|
setw -g allow-rename on
|
|
```

# Font and Unicode Display Issues
|
|
|
|
## Missing emoji and unicode symbols
|
|
|
|
**Issue:** Emojis show as boxes or missing characters, unicode symbols don't display properly.
|
|
|
|
**Solution:** Install comprehensive unicode font packages:
|
|
```bash
|
|
sudo pacman -S noto-fonts-emoji noto-fonts-extra
|
|
fc-cache -f
|
|
```
|
|
|
|
## Nerd Font icons not displaying
|
|
|
|
**Issue:** Developer icons (programming languages, git symbols, file types) show as blank spaces or boxes.
|
|
|
|
**Root cause:** Terminal emulator not configured to use Nerd Font as primary font.
|
|
|
|
**Solution:**
|
|
1. Install Nerd Fonts:
|
|
```bash
|
|
sudo pacman -S ttf-iosevkaterm-nerd ttf-jetbrains-mono-nerd
|
|
fc-cache -f
|
|
```
|
|
|
|
2. Configure terminal to use Nerd Font as primary font
|
|
3. For wezterm, ensure config includes:
|
|
```lua
|
|
config.font = wezterm.font_with_fallback {
|
|
'IosevkaTerm Nerd Font',
|
|
'JetBrainsMono Nerd Font Mono',
|
|
'Noto Color Emoji'
|
|
}
|
|
```
|
|
|
|
**Testing:** Use printf with direct codepoints:
|
|
```bash
|
|
printf "Icons: \\ue702 \\uf121 \\uf015 \\uf07b\\n"
|
|
```
|
|
|
|
## Ancient/exotic script support
|
|
|
|
**Comprehensive coverage achieved with:**
|
|
- `noto-fonts` (base unicode)
|
|
- `noto-fonts-cjk` (Chinese/Japanese/Korean)
|
|
- `noto-fonts-emoji` (color emoji)
|
|
- `noto-fonts-extra` (additional scripts)
|
|
|
|
Successfully displays: Egyptian hieroglyphs, Cuneiform, Nordic runes, Hungarian rovás, Arabic, Chinese, Japanese, Korean, Thai, Hindi, Hebrew, Greek, Tamil.

# Cannot tile windows by drag and dropping
|
|
|
|
Keyboard workaround: Go to Settings > Window Manager > Keyboard, set up tiling shortcuts (set to Super+arrow keys)
|
|
|
|
# Additional Known Issues (TODO Items)
|
|
|
|
## Tmux battery indicator missing until config reload
|
|
|
|
**Issue:** Battery indicator doesn't appear in tmux status line immediately after starting tmux.
|
|
|
|
**Temporary workaround:** Reload tmux config with `Prefix + r` or restart tmux session.
|
|
|
|
**Status:** Investigation needed
|
|
|
|
## TTY fallbacks needed
|
|
|
|
**Issue:** When not in X11/graphical mode, nvim and tmux need proper fallback configurations.
|
|
|
|
**Status:** Completed
|
|
|
|
**Solutions implemented:**
|
|
- ✅ **nvim:** TTY detection and color scheme fallback configured
|
|
- ✅ **Font:** Selected ter-124b (12x24 bold) for good readability
|
|
- ✅ **Keyboard:** Colemak layout with caps lock remapped to backspace
|
|
- ✅ **Caps lock fix:** Uses systemd service with `setkeycodes 3a 14`
|
|
|
|
**Configuration files:**
|
|
- `/etc/systemd/system/caps-backspace.service` - Permanent caps lock remapping
|
|
- TTY font testing script: `~/.local/scripts/test-fonts.sh`
|
|
|
|
## TTY Caps Lock Not Working as Backspace
|
|
|
|
**Issue:** With colemak keymap loaded, caps lock acts like Control instead of backspace in TTY.
|
|
|
|
**Root cause:** Colemak keymap maps caps lock to Control, which conflicts with tmux navigation keys.
|
|
|
|
**Solution:** Use `setkeycodes` to remap at scancode level:
|
|
```bash
|
|
sudo setkeycodes 3a 14 # Map caps lock scancode to backspace keycode
|
|
```
|
|
|
|
**Permanent fix:** Systemd service created at `/etc/systemd/system/caps-backspace.service`
