Unified installation, simplified deployment

A unified installation design lets a single system image serve both teacher and student endpoints — no need to build separate student or teacher images, greatly simplifying deployment and lowering O&M costs.

One software, two roles

The system identifies roles automatically: once launched, the teacher side automatically becomes the control end, and the student side automatically connects to the teacher side. Using the tags pushed down by the cloud desktop, it automatically distinguishes teacher and student sides, avoiding repeated installation within the cloud desktop.

No separate images for teacher and studentCoreA unified installation package eliminates the need to distinguish student / teacher images; roles are detected automatically and delivered with the cloud desktop, ready to use out of the box.
Linux / XinchuangNatively recommendedProvides amd64 and arm64 (Phytium / Kunpeng / Loongson) .deb packages, supporting UOS / Kylin / Ubuntu — Xinchuang labs and Windows labs share the same electronic classroom software.

cc-class 教师端 · Ubuntu Xinchuang Server Room真实界面（Screen Broadcast / Assignment Collection / One-click blackout）

Linux / Xinchuang native, primary focus —— Xinchuang electronic-classroom software

Built for Xinchuang server rooms: the same cc-class runs simultaneously on Windows and UOS / Kylin / Ubuntu, natively covering Phytium, Kunpeng, Loongson and other Xinchuang CPUs, with functionality and UI fully identical to Windows labs.

Multi-architecture Xinchuang coverage

Offers amd64 and arm64 installation packages with native support for Phytium / Kunpeng / Loongson machines, and runs out of the box on UOS, Kylin, and Ubuntu 20.04/22.04/24.04.

.deb online / offline installation

Online apt install It automatically pulls dependencies; when the lab has no apt source, it uses an offline package containing all dependencies and install.sh,Installs in one click, fully offline throughout。

systemd-guarded auto-start

The student endpoint registers as a systemd service and auto-starts at boot to automatically connect to the teacher endpoint; the teacher endpoint launches on demand and reconnects automatically when disconnected, requiring no manual attendance.

Role detection · Xorg auto-adaptation

It automatically identifies teacher and student machines by computer name; the installation package automatically switches the session to Xorg, ensuring screen broadcasting and remote control work reliably on Linux.

Screen Monitoring Rotation

View thumbnails of all students' screens in real time, with polling monitoring or grid view supported, to promptly detect and intervene in violations.

Remote Takeover & Control

Synchronized keyboard-and-mouse control of student desktops supports a hands-on guidance mode, letting you tutor and troubleshoot without leaving the teacher's machine.

Distribute materials / collect and return assignments

Materials are distributed with one click, and homework, reports, and exam files are automatically collected and archived by class / student ID / seat, with resumable transfer.

Batch deployment of multiple drives

Select courseware from multiple drives/paths on the teacher's machine simultaneously and deliver it in bulk to student machines in one operation.

One-Click Screen Blackout & Silence

Centrally lock students' displays and keyboard/mouse input, disable network / USB, and prevent students from terminating the client process.

Check-In & Attendance

After students enter their name, student ID and class, information is collected and files organized automatically, then archived into the matching folder.
