# Installed packages — candidates for removal (reTerminal kiosk)

Device: **10.20.50.147** (backup image).  
Goal: shrink the image by removing apps and services not needed for a Chromium kiosk.

**Keep:** Chromium, LightDM, labwc, kanshi, maliit-keyboard, plymouth, openssh, NetworkManager, WayVNC (if you use it), wf-panel-pi, autotouch, wmctrl, wlr-randr, python3-gi, GTK/labwc themes in use.

## 5. KDE Plasma apps (many) — **review; remove what you don’t use**

You’re using **labwc** as the session, but a lot of KDE packages are still installed (dolphin, konsole, kate, etc.). Removing big KDE apps can free a lot of space; keep anything your kiosk or panel needs.

**File manager / desktop:**
- `dolphin` `dolphin-data` `dolphin-doc` `dolphin-plugins`
- `kde-baseapps`
- `baloo6` (file indexer)

**Editors / text:**
- `kate` `kate-data`
- `kwrite`
- `mousepad` (XFCE editor)

**Terminal:**
- `konsole` `konsole-kpart`

**Browser / bookmarks:**
- `konqueror` `konqueror-data` `konqueror-doc`
- `keditbookmarks`

**System / config:**
- `kinfocenter`
- `khelpcenter` `khelpcenter-data`
- `ksystemstats`
- `kfind`
- `kmenuedit`
- `kdialog`
- `kde-cli-tools` `kde-cli-tools-data`
- `kde-config-screenlocker` (if you don’t use lock screen)
- `kde-config-sddm` (you use LightDM, not SDDM)
- `kde-spectacle` (screenshot)
- `kscreen` (display config; you use kanshi)

**Connectivity / sharing:**
- `kdeconnect` `kdeconnect-libs`
- `kdenetwork-filesharing`

**Wallet / accounts:**
- `kwalletmanager`
- `kwallet6`
- `kaccounts-providers`

**Backup:**
- `kup-backup`

**Other:**
- `drkonqi` (KDE crash handler)
- `kactivitymanagerd`
- `kde-inotify-survey`
- `kdegraphics-thumbnailers`
- `ffmpegthumbs`
- `frameworkintegration6`

Example (remove a block of KDE apps; adjust to what you want to keep):

```bash
sudo apt remove --purge dolphin dolphin-data dolphin-doc dolphin-plugins kde-baseapps baloo6 kate kate-data kwrite konsole konsole-kpart konqueror konqueror-data konqueror-doc keditbookmarks kinfocenter khelpcenter khelpcenter-data ksystemstats kfind kmenuedit kdialog kde-spectacle kscreen kdeconnect kdeconnect-libs kdenetwork-filesharing kwalletmanager kup-backup drkonqi kactivitymanagerd kde-inotify-survey kdegraphics-thumbnailers ffmpegthumbs
sudo apt autoremove --purge
```

**Keep** (likely used by labwc/panel/theme): things like `breeze`, `breeze-gtk-theme`, `kwin-wayland`/`kwin-common` (if labwc or something depends on them), `plasma-browser-integration` if you want Chromium integration.

---

## 6. Image / media tools — **safe to remove** if not needed

| Package | Notes |
|---------|--------|
| `eom` `eom-common` | Eye of MATE image viewer |
| `imagemagick` `imagemagick-7.q16` `imagemagick-7-common` | Image conversion |
| `gimp` (if present) | Image editor |
| `grim` | Wayland screenshot (keep only if you use it) |

```bash
sudo apt remove --purge eom eom-common imagemagick imagemagick-7.q16 imagemagick-7-common
sudo apt autoremove --purge
```

---

## 7. Archive / backup tools — **optional**

| Package | Notes |
|---------|--------|
| `7zip` | 7z archives |
| `bup` `bup-doc` | Backup tool |
| `cryfs` | Encrypted filesystem |

```bash
sudo apt remove --purge 7zip bup bup-doc cryfs
sudo apt autoremove --purge
```

---

## 8. Bluetooth — **optional** (remove if no BT devices)

| Package | Notes |
|---------|--------|
| `bluedevil` | KDE Bluetooth |
| `bluez` `bluez-obexd` `bluez-firmware` | Bluetooth stack |

Removing these will disable Bluetooth. If the kiosk never uses BT:

```bash
sudo apt remove --purge bluedevil bluez bluez-obexd bluez-firmware
sudo apt autoremove --purge
```

---

## 9. Spell-check / dictionaries — **optional**

| Package | Notes |
|---------|--------|
| `aspell` `aspell-en` | Spell checker |
| `hunspell-en-us` `hunspell-en-gb` `hunspell-de-de` `hunspell-fr` `hunspell-fr-classical` `hunspell-nl` | Dictionaries |
| `hyphen-en-gb` | Hyphenation |
| `dictionaries-common` | Dictionary config |

```bash
sudo apt remove --purge aspell aspell-en hunspell-de-de hunspell-en-gb hunspell-en-us hunspell-fr hunspell-fr-classical hunspell-nl hyphen-en-gb dictionaries-common
sudo apt autoremove --purge
```

| `fprintd` `libpam-fprintd` | Fingerprint (usually not on reTerminal) |
| `ModemManager` | Modem (remove if no modem) |
| `evolution-data-server-common` | Evolution PIM (often dependency of others) |

---

## 11. Optional services to disable (not necessarily remove)

- `cups.service` — disable if you removed CUPS
- `rpcbind.service` — disable if you removed rpcbind
- `nfs-blkmap.service` — disable if no NFS
- `bluetooth.service` — disable if you removed Bluetooth
- `ModemManager.service` — disable if no modem

```bash
sudo systemctl disable cups.service
sudo systemctl disable rpcbind.service
sudo systemctl disable nfs-blkmap.service
# etc.
```

---

## Suggested order of removal

1. **Printing:** CUPS + ghostscript + hplip + ipp-usb  
2. **NFS/RPC:** rpcbind (and nfs-* if present)  
3. **Development:** build-essential, gcc, g++, git, gdb, etc.  
4. **Document/office:** evince, catdoc  
5. **KDE apps:** dolphin, kate, konsole, konqueror, spectacle, kscreen, kdeconnect, etc. (keep what labwc/panel needs)  
6. **Image/media:** eom, imagemagick  
7. **Archive/backup:** 7zip, bup, cryfs  
8. **Bluetooth:** if not needed  
9. **Spell-check/dictionaries:** if not needed  
10. **Misc:** alacarte, galculator, fprintd, ModemManager (if not needed)

After each group:

```bash
sudo apt autoremove --purge
sudo apt clean
```

Then re-check with `dpkg -l` and `df -h` to see space saved. If you want a single “remove list” file for scripting, say which categories to include and we can generate one.
