Credits

Original plugin by zty199. Forked and extended by K4RLT. HiDPI fix by @DonkeyKongG3me.

What it does

A repackaged build of dde-session-shell — the Deepin lock screen and greeter — with custom patches applied on top of the official source.

Patches included

• Font rendering fixes for CJK characters on the lock screen
• Layout tweaks for a cleaner, more centered appearance

Requirements

• Deepin / UOS desktop environment

Installation

sudo dpkg -i dde-session-shell-repack.deb

Then log out and back in to apply.

Uninstall

sudo apt install --reinstall dde-session-shell

What it does

Changes popupX in launcheritem.qml so the windowed launcher opens centered on screen rather than above the dock icon.

Installation

First disable Solid System Read-Only Protection in Control Center → System → Developer Options, then:

sudo cp launcheritem.qml /usr/share/dde-shell/org.deepin.ds.dock.launcherapplet/launcheritem.qml
pkill dde-shell; nohup dde-shell &

No recompiling needed — it's a plain QML file loaded at runtime.

What it does

Adds native thumbnail support for Krita .kra and .krz files directly inside the DDE File Manager. Merged into linuxdeepin/dde-file-manager#3810 — no separate plugin or workaround required on Deepin.

How it works

Krita embeds a flattened mergedimage.png (Krita ≥ 3) or a preview.png inside every .kra / .krz ZIP archive. The new krataThumbnailCreator extracts that image using minizip and feeds it directly into DFM's thumbnail pipeline — no Krita installation needed.

Changes merged

• Added kTypeAppKrita MIME constant to dfm_global_defines.h
• Registered krataThumbnailCreator in ThumbnailFactory
• Added application/x-krita to mimeTypeSupportStrategy (unconditional) and the size-limit map
• Added libminizip-dev dependency to DFMLibraryConfig.cmake and debian/control

Tested on

Deepin 25 — thumbnails generate correctly for both mergedimage.png and preview.png variants.

The bug

Official bug ID PMS BUG-364263. The multitask-view button's rendered box is 0.8× the dock item max size, but app icons are drawn at 9/14 ≈ 0.64×. TaskManager.qml didn't account for that mismatch, so the visible gap next to the multitask-view button came out smaller than the gap between app icons.

The fix

Fixed upstream by Ivy233 (UnionTech) in commit 24ccd616, June 3 2026. Adds a computed startPadding to TaskManager.qml that cancels out the ratio mismatch, applied as a left/top margin on the app icon container.

Who needs this

Only systems on a dde-shell build older than June 3 2026. If your build already includes this commit, don't patch — you already have the fix.

Installation

sudo cp /usr/share/dde-shell/org.deepin.ds.dock.taskmanager/TaskManager.qml ~/TaskManager.qml.bak
cd /usr/share/dde-shell/org.deepin.ds.dock.taskmanager
sudo patch -p1 --dry-run < 0001-fix-dock-align-multitask-view-to-first-app-gap.patch
sudo patch -p1 < 0001-fix-dock-align-multitask-view-to-first-app-gap.patch
killall dde-dock

Always run --dry-run first — if it reports a failed hunk, your build has diverged from this exact commit and the patch needs manual reconciliation instead of forcing it.

Revert

sudo cp ~/TaskManager.qml.bak /usr/share/dde-shell/org.deepin.ds.dock.taskmanager/TaskManager.qml
killall dde-dock

Tested on

Deepin, dock build dated 2026-05-20 → confirmed fixed after patching and restarting dde-dock.
