# 麒麟鼠标掉帧继续排查（2026-11-04）
|
||||
|
||||
本轮保留的改动是**仅麒麟主机协商 limited 视频范围**，避免旧版 Sunshine 的额外全范围转换。真实桌面和视频仍为2560×1440、H.264、30Mbps，正常卡片仍请求30FPS。同场景45FPS请求的对照中，实际渲染由21.42提高至28.81FPS（约35%）；尚未达到Windows约43～44FPS的既有水平，也未证明物理鼠标到屏幕延迟与Windows相同。
|
||||
|
||||
## 现状与改动
|
||||
|
||||
- Sunshine恢复官方v0.21.0原文件，SHA256为`1c3099bf924db3aee759b3d7c05e012569ef8650c400d1479144398795decc71`。保持X11、ultrafast、zerolatency、原单线程、暂停UKUI合成器，无额外capability。
|
||||
- 盒子`vdi-moonlight-rkmpp`支持逐主机色彩范围文件：`${XDG_CONFIG_HOME:-$HOME/.config}/vdi-terminal/host-color-range/<host>`，内容只允许`0`（limited）或`1`（full）。仅配置`192.168.1.71`为`0`。显式`COLOR_RANGE_OVERRIDE`环境变量优先，无配置的主机沿用Moonlight默认行为。
|
||||
- 服务端实际日志从`Color range: [JPEG]`变为`[MPEG]`；客户端解码后仍扩展成正常屏幕RGB，不是将黑白截成灰色。未改客户端二进制、分辨率、码率、Windows/Ubuntu卡片或PVE配置。
|
||||
- wrapper已部署，语法检查、麒麟/Windows/Ubuntu隔离、显式环境覆盖和非法配置拒绝检查通过，见[配置验证](evidence/kylin-mouse-20261104/wrapper-profile-check.json)。用户明确允许切回麒麟后，已从正常kiosk列表连接，确认父进程为kiosk、2560×1440/30FPS/30Mbps、`COLOR_RANGE_OVERRIDE=0`，实际2K RKMPP/EGL解码和服务端`[MPEG]`日志通过。最终保留麒麟桌面连接，见[正常入口](evidence/kylin-mouse-20261104/final-kiosk-connection.json)及[最终桌面](evidence/kylin-mouse-20261104/final-normal-desktop.png)。
|
||||
|
||||
备份：盒子`~/vdi-terminal/backups/kylin-mouse-20261104/`有原wrapper和desktops.json；麒麟同目录有原sunshine.conf。回退删除麒麟色彩范围文件，下次连接恢复原协商；必要时恢复wrapper备份。没有修改其他主机的配置文件。
|
||||
|
||||
## 测试证据
|
||||
|
||||
局部运动GTK源约60FPS，所有以下有效轮次均核对真实未锁屏测试窗口，并发送F8和24次交替点击。每轮请求2560×1440/45FPS/30Mbps，短时顺序测试；网络延迟和抖动有波动，不作为长期保证。
|
||||
|
||||
| 服务端 / 协商 | 实际渲染FPS | 解码ms | 队列ms | 采用情况 |
|
||||
| --- | ---: | ---: | ---: | --- |
|
||||
| 原程序 / full |21.42|7.48|0.15|对照|
|
||||
| 原程序 / limited |28.81|6.90|0.23|保留limited协商|
|
||||
| 原程序 / limited / 两线程 |25.67|7.09|0.12|已撤销|
|
||||
| BGRA兼容副本 / limited |27.17|6.85|0.11|已撤销|
|
||||
| BGRA + full-chroma副本 / limited |25.61|10.38|0.13|已撤销|
|
||||
| BGRA + bilinear副本 / limited |30.79|7.44|0.13|收益不足以保留二进制维护和色度采样变化，已撤销|
|
||||
|
||||
数据及日志索引见[测试汇总](evidence/kylin-mouse-20261104/trial-summary.json)。这轮没有把请求45FPS写成真实达到45FPS。原full与limited静态区域的RGB平均绝对差约0.3～1.3/255，黑白条纹仍包含0和255，小字号与彩色文字已视觉核对；这不是逐像素无损承诺。见[色彩核对](evidence/kylin-mouse-20261104/color-comparison.json)、[limited实际截图](evidence/kylin-mouse-20261104/limitedrange-2k45.png)。
|
||||
|
||||
原始进程线程观察显示Sunshine有一个线程接近占满单核，而盒子呈现队列通常约0.1～0.2ms。通过Linux软件CPU-clock采样，旧版静态FFmpeg的逐像素色彩转换出现在热点中；ELF已剥离符号，地址区间只能粗略分类，不能当作精确函数耗时。记录见[采样说明](evidence/kylin-mouse-20261104/sampling-hotspots.json)。
|
||||
|
||||
## 未采用的兼容实验
|
||||
|
||||
仅对精确SHA256匹配的原文件创建三个独立副本，未覆盖原文件。根据v0.21.0源码与反汇编，两个`sws_getContext`调用的BGR0立即数由121改为BGRA的28；后续分别测试附加`SWS_FULL_CHR_H_INP`或改为`SWS_BILINEAR`。只对独立副本做单文件KYSEC认证。实验服务drop-in已删除，三个副本确认没有进程使用后删除，原版SHA和活动服务已读回确认，见[清理记录](evidence/kylin-mouse-20261104/restored-original.json)、[恢复状态](evidence/kylin-mouse-20261104/restored-host-state.txt)。未保留任何实验二进制作为正常入口。
|
||||
|
||||
依据：[Sunshine v0.21.0 video.cpp](https://github.com/LizardByte/Sunshine/blob/v0.21.0/src/video.cpp)、[FFmpeg n6.0转换初始化](https://github.com/FFmpeg/FFmpeg/blob/n6.0/libswscale/x86/swscale.c)、[FFmpeg色彩范围转换](https://github.com/FFmpeg/FFmpeg/blob/n6.0/libswscale/swscale.c)。
|
||||
|
||||
## 回显延迟边界及后续
|
||||
|
||||
增加了F9翻转画面黑白标记的探针：盒子在发出合成按键前计时，轮询实际解码视频所在X11根窗口，看到标记翻转后结束。该方法包含工具启动、串流往返和轮询，排除物理USB输入和显示面板扫描。
|
||||
|
||||
用户授权切回麒麟后，使用同一个未锁屏的动态源、原版服务端、相同2560×1440/30FPS/30Mbps完成顺序对照，每组24次，均无超时：
|
||||
|
||||
| 配置 | 实际渲染FPS | 解码ms | 合成输入回显P50 ms | P95 ms |
|
||||
| --- | ---: | ---: | ---: | ---: |
|
||||
| full原协商 |23.35|9.54|150.99|186.38|
|
||||
| limited保留配置 |27.25|6.96|143.57|173.03|
|
||||
|
||||
见[完整对照数据](evidence/kylin-mouse-20261104/final-response-comparison.json)。视频更新约提高17%；回显分布重叠、网络延迟也不同，24个样本不足以证明显著或大幅的延迟下降，更不能宣称达到Windows几乎无延迟。该探针也不能替代物理输入到屏幕的测量。
|
||||
|
||||
此前full/30FPS的一组24次P50约163ms、P95约190ms，后续超出临时串流期限，盒子随后已连接Windows，完整收尾未完成；保留原始JSON和部分日志用于审计，不混入上述完整对照。临时GTK和临时串流服务已停止，最终使用正常kiosk串流。
|
||||
|
||||
麒麟2vCPU的软件捕获/颜色转换/编码链路仍然限制视频更新。若目标是Windows同等的视频响应，需要进一步实现并验证转换并行化/硬件编码；若目标是指针本身不等待视频，则需要实现自动形状同步、显隐、热点和可靠交接的独立光标通道。现有受控原型尚不满足这一要求，不能用普通本地箭头叠加冒充完成。

# 麒麟真实 2K 与响应优化（2026-11-04）
|
||||
|
||||
后续鼠标掉帧排查已保留逐主机limited协商，同场景原程序对照约21→29FPS，尚未达到Windows水平，见[继续排查记录](kylin-mouse-20261104.md)。下文为本轮之前的真实2K落地记录。
|
||||
|
||||
麒麟已从 1080p 升级为真实 **2560×1440** 桌面与视频，盒子麒麟卡片配置为 **30 FPS、30Mbps、H.264**。分辨率与码率已与 Windows 对齐；实际帧率尚未达到 Windows 的水平。保留暂停 UKUI 桌面合成器的优化，局部运动短测由约 19 FPS 提高至约 23 FPS。物理鼠标到屏幕的端到端延迟未测量。
|
||||
|
||||
## 最终部署
|
||||
|
||||
| 项目 | 生效配置 |
|
||||
| --- | --- |
|
||||
| PVE VM 101 kylin-test | `vga=std,memory=64`，其他字段保持原值 |
|
||||
| 麒麟 Virtual-1 | 2560×1440，约59.95Hz，自定义模式 `2560x1440_60.00` |
|
||||
| Sunshine | v0.21.0，X11 捕获，libx264 ultrafast / zerolatency，原单线程策略 |
|
||||
| 盒子麒麟对象 | `desk-kylin-01`，192.168.1.71 / Desktop，2560×1440 / 30 FPS |
|
||||
| 客户端 | 原 RKMPP 硬解、DRM PRIME、EGL/GLES、latest-frame 队列、无VSync/无frame-pacing |
|
||||
| 视频码率 | 30Mbps，沿用现有产品对2K的规则；Windows同为30Mbps |
|
||||
|
||||
用户明确授权后，已正常关闭 VM 101 至 stopped，修改显存并重新启动。配置差异检查确认只有 `vga` 变化；未重启 PVE、Windows 或 Ubuntu。麒麟内部 PCI BAR 已识别为64MB。见 [执行记录](evidence/kylin-quality-20261104/vm101-execution.json)、[配置差异](evidence/kylin-quality-20261104/vm101-config-change.json)。
|
||||
|
||||
服务 `~/.config/systemd/user/vdi-sunshine.service` 增加启动前创建、添加和切换2K模式的步骤，时序为：
|
||||
|
||||
```text
|
||||
241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
|
||||
```
|
||||
|
||||
已通过“切回1080p、删除自定义模式、启动服务”的实测，确认能重新创建并进入2K。新服务配置尚未通过第二次整机重启验收。麒麟 test1 图形会话在本次开机后存在；未改变其登录或锁屏策略。
|
||||
|
||||
服务启动后经 `org.ukui.KWin /Compositor` 暂停桌面合成，停止服务时恢复合成；读回最终 `active=false`。这针对当前UKUI/Xorg现场环境，调用失败不阻止 Sunshine 本体启动。原 `kwinrc` 未修改。见 [最终服务](evidence/kylin-quality-20261104/final-sunshine.service)、[最终配置](evidence/kylin-quality-20261104/final-sunshine.conf)。
|
||||
|
||||
## 实际验证
|
||||
|
||||
临时 GTK 窗口展示小字号文字、单像素条纹、彩色文字与局部运动块；有效轮次的源绘制约59FPS。只在确认 Moonlight 窗口焦点后注入输入。测试后窗口已关闭。
|
||||
|
||||
| 有效2K动态桌面轮次 | 实际渲染 FPS | 解码 ms | 帧队列 ms | 呈现 ms |
|
||||
| --- | ---: | ---: | ---: | ---: |
|
||||
| X11 / 单线程 / 合成开启 | 18.89 | 14.13 | 0.09 | 2.12 |
|
||||
| X11 / 两线程 / 合成开启 | 18.85 | 8.96 | 0.29 | 2.12 |
|
||||
| X11 / 单线程 / 合成暂停（采用） | 22.97 | 9.04 | 0.12 | 2.11 |
|
||||
|
||||
这是约20秒保持加连接与输入阶段的短测，网络延迟和抖动并不完全相同，不能视为长期性能保证。客户端帧队列很短，未证明物理输入延迟下降；2K实际23FPS也不能宣传为稳定30或45FPS。
|
||||
|
||||
- 实际桌面与视频尺寸均为2560×1440，已核对盒子截屏，文字不再由1080p放大。见 [2K动态图](evidence/kylin-quality-20261104/2k30-desktop-no-compositor-valid.png)。
|
||||
- 当前有效测试进程记录中，48次跨屏交替点击全部落在预期坐标（误差不超过1px），收到F8。见 [输入结果](evidence/kylin-quality-20261104/2k-input-result.json) 和 [原始事件](evidence/kylin-quality-20261104/2k-valid-source-and-input.log)。
|
||||
- 从正常 kiosk 麒麟卡片连接、退出回列表、再次连接，确认2K参数与RKMPP/EGL路径；最终保持正常麒麟桌面连接供用户体验。见 [重连结果](evidence/kylin-quality-20261104/final-kiosk-check.json)、[正常入口日志](evidence/kylin-quality-20261104/final-kiosk-client.log)、[最终桌面](evidence/kylin-quality-20261104/final-desktop.png)。
|
||||
- 只修改盒子的麒麟对象，Windows、Ubuntu对象经结构比较保持原值；没有修改产品源码、客户端二进制和全局渲染配置。
|
||||
|
||||
部分早期2K轮次在长时间暂停后采到了锁屏画面，已经从有效性能结论中排除：`2k30-ultrafast-thread1`、`2k30-damage-thread1`、`2k30-damage-thread2`。这些原始文件保留用于审计。当前有效轮次均为文件名含 `desktop-...-valid` 的三轮，截图与输入记录已核对。测试源码也改为只重绘运动区域，不能直接将新旧不同负载的数字相减作为提升幅度。
|
||||
|
||||
曾探测KMS捕获，但此虚拟显卡上未初始化成功，已恢复X11；最终 Sunshine 实体二进制与入口的 `getcap` 均为空，未保留该探测使用的额外 capability。两线程、较慢压缩预设未带来适合本机的收益，均未保留。
|
||||
|
||||
## 原因、边界与回退
|
||||
|
||||
原默认 Standard VGA 只有16MB。Linux5.15 DRM VRAM helper限制单帧缓冲不超显存一半，2560×1440×4字节的单帧约14.06MiB，双缓冲约28.13MiB，因此原2K切换失败；增加到64MB后解除限制。参考 [内核实现](https://github.com/torvalds/linux/blob/v5.15/drivers/gpu/drm/drm_gem_vram_helper.c)。
|
||||
|
||||
麒麟目前只有2个虚拟CPU且使用软件编码。这次完成了真实2K、码率对齐、合成开销优化和基础输入/重连验证；45FPS、长时间高动态负载、物理输入延迟、音质、生产多用户隔离仍未验收。
|
||||
|
||||
备份位置：
|
||||
|
||||
- 麒麟 `/home/test1/vdi-terminal/backups/kylin-quality-20261104/`：原 sunshine.conf、vdi-sunshine.service、kwinrc、xrandr-before.txt。
|
||||
- 盒子 `/home/armbian/vdi-terminal/backups/kylin-quality-20261104/desktops.json`。
|
||||
- PVE [原配置快照](evidence/kylin-quality-20261104/vm101-config-before.json)，原 `vga` 字段未设置。
|
||||
|
||||
回退先正常退出串流；恢复盒子备份（若其他桌面后续有修改，只恢复麒麟对象）；在麒麟恢复原 Sunshine 配置与服务，`systemctl --user daemon-reload` 后重启服务。当前服务停止会恢复合成；原服务将显示器设回1080p。64MB显存可保留；如需完全恢复原PVE设置，删除显式 `vga` 字段并在维护窗口正常关机再启动。

||||

||||
