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):

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)

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

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:

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

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

---

10. Miscellaneous apps

Package	Notes
alacarte	Menu editor

---

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

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:

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.
