# GPU修复后刷新率与鼠标画面优化验收（2026-11-03）
|
||||
|
||||
## 结论
|
||||
|
||||
Windows虚拟屏已调整为2560×1440、60Hz，登录脚本已备份并更新；客户端默认已设为45FPS，并通过正常选择桌面入口重连。当前盒子的Xorg/EGL路径在请求60FPS时实际只能渲染约46FPS，因此不宣称稳定2K60。45FPS短测实际44.22FPS，持续测试43.14FPS；相对30FPS基线29.83FPS提高约45%～48%，排队约1.3～1.6ms。
|
||||
|
||||
## GPU复核
|
||||
|
||||
本轮实际查询NVIDIA错误码0，驱动582.78，vBIOS 84.04.2b.00.13。动态串流期间Sunshine实际创建h264_nvenc，NVIDIA有1个编码会话，检查时编码引擎约24%。运维报告的重启测试作为其提供的验收记录，本轮未自行重启VM、宿主或GPU，也未修改直通和ROM配置。
|
||||
|
||||
## 同一修正测试源对照
|
||||
|
||||
修正后的Windows测试窗口实测约59FPS，避免了原WinForms定时器将源限制到约32FPS的问题。所有测试保持2560×1440、H.264、30Mbps、RKMPP硬解；默认客户端为已有两个输入补丁的版本，第三补丁调度未启用。除同步实验外，均关闭VSync与帧步调。
|
||||

||||

|
||||
| VDD60 / 客户端60、原队列 | 58.81 / 46.10 | 7.6ms | 7.13ms | 36.13ms | 10.28% |
|
||||
| VDD60 / 客户端60、精确尺寸nearest实验 | 58.20 / 42.01 | 7.5ms | 6.94ms | 7.66ms | 27.77% |
|
||||
| VDD60 / 客户端60、VSync开/帧步调关 | 57.88 / 24.39 | 7.5ms | 7.26ms | 8.12ms | 57.80% |
|
||||
| VDD60 / 客户端45、最新帧队列 | 44.84 / 44.22 | 7.6ms | 8.54ms | 1.30ms | 1.38% |
|
||||
| VDD60 / 客户端45、持续测试 | 43.98 / 43.14 | 7.6ms | 7.32ms | 1.55ms | 1.91% |
|
||||
|
||||
上表“客户端队列丢弃指标”来自上游标成`Frames dropped due to network jitter`的统计，但实际字段是`pacerDroppedFrames`，本项目最新帧队列也计入其中。不能把它全部归因于网络，原队列溢出统计也并不完整；应结合接收/解码/渲染FPS及帧队列时间评估。上述会话真正的网络丢帧字段均为0%，网络延迟约2～7ms；这些是现场顺序测试，不是严格实验室基准。
|
||||
|
||||
60FPS会话采样盒子图形核心约89%～95%负载、800MHz；DDR频率已在786MHz最高公布档位，MATE合成器关闭。测试温度约62～65℃，没有通过提高频率/电压或更改CPU/GPU调速器来制造结果。原队列没有提高帧率却增加排队，nearest采样和VSync实验均未显示收益，未部署。
|
||||
|
||||
nearest实验保留在`terminal/moonlight/experiments/0004-vdi-egl-exact-size-sampling.patch`供复查，已从盒子正常源码撤回，不进入默认构建流程。正常二进制SHA256仍为`35de7b1a4ade583823b23b5f2e012307f6d0a3848c8eb97bd6d4de9660afa00f`。
|
||||
|
||||
## 配置和回退
|
||||
|
||||
- Windows实际活动VDD编号已变为DISPLAY3，工具动态查找，未写死设备号。旧DISPLAY2备份不能直接作为新设备的恢复依据，因此探测器增加`--backup-tag`区分验收批次。
|
||||
- `tools/set-2k-display.ps1`默认60Hz，支持`-RefreshRate 30`回退；已更新原VDISet2KDisplay登录任务使用的脚本，未修改任务动作或用户。
|
||||
- Windows部署前原脚本和任务XML备份：`C:\ProgramData\VDI\backups\display-refresh-20261103-142920`。部署工具按本次新生成的结果日志和任务退出码确认成功，随后独立Query确认60Hz。本轮没有重启验证登录触发。
|
||||
- `tools/run-mouse-display-probe.py Apply --hz 30 --backup-tag nvenc-20261103`可临时恢复30Hz；要保持30Hz应恢复原登录脚本，或将登录任务脚本参数设为`-RefreshRate 30`。
|
||||
- `tools/set-terminal-fps.py --fps 45 --apply`只更改盒子Windows桌面票据FPS，自动备份和原子写入，不更改其他桌面；回退用`--fps 30 --apply`。
|
||||
|
||||
部署工具前两次因Windows任务调度器LastRunTime与墙上时钟不同步而误判成功任务为失败，已自动恢复旧脚本；随后改为新结果日志证明执行新鲜度，部署成功。受配置切换影响的`nvenc45-sustained`不纳入持续测试结论，重新执行`nvenc45-sustained-final`。
|
||||
|
||||
## 持续测试和现场收尾
|
||||
|
||||
`nvenc45-sustained-final`在视频就绪后注入20秒鼠标移动和32次点击，再持续120秒，正常退出。接收43.98/渲染43.14FPS，主机平均7.6ms、解码7.32ms、排队1.55ms、呈现1.55ms，实际网络丢帧0%。这是约两分半钟的动态会话结果，不是长期稳定性保证。
|
||||
|
||||
三组Windows点击记录共256次左右交替点击，脚本校验全部符合预期，包含被排除的持续性能试验中的32次；点击正确性可核验，但其帧率数据不纳入持续性能结论。修正测试源在保存的状态中约59.4～59.8FPS，足够进行本轮对照。
|
||||
|
||||
已执行`set-terminal-fps.py --fps 45 --apply`，原30帧票据备份于盒子`~/vdi-terminal/backups/fps-20261103-143333-297521/desktops.json`。只改变Windows卡片FPS，其余桌面、分辨率和编码配置保持原值。
|
||||
|
||||
已停止并删除VDIInputLatencyBench临时任务；最终Windows查询确认`benchmark_task_present=False`。通过正常kiosk页面点击Windows连接，实际新进程PID31694带`--resolution 2560x1440 --fps 45`，RKMPP/DRM PRIME/EGL路径正常。再次查询错误码0、NVENC会话1、编码占用18%，Sunshine本次实际创建h264_nvenc。显示守护active，正常客户端二进制未换成实验版本。
|
||||
|
||||
证据目录：`docs/evidence/2k60-20261103/`，包含逐会话日志、点击记录、最终GPU/编码查询和页面截图。实际拖窗与鼠标的主观体验仍需用户现场确认；本轮自动点击和统计不能代替物理输入到屏幕测量。
|
||||
|
||||
## 后续边界
|
||||
|
||||
独立光标尚未实现，仍保留单个Windows远程白色光标。下一阶段要进一步达到稳定2K60，需要验证更低开销的显示路径及正式Weston/Wayland架构，或评估终端硬件；当前不能通过提高FPS参数或安装所谓流畅插件绕过呈现瓶颈。独立光标双方协议与单光标交接设计见`docs/independent-cursor-design-20261103.md`。本轮未测量物理输入到屏幕的P50/P95，不能称零延迟。

# Windows仅保留2K主屏（2026-11-03）
|

用户条件：只有在不影响当前2K屏幕使用时才调整。已完成并读回：Windows仅一个活动桌面输出，保留Virtual Display Driver主屏2560×1440@60，盒子原Moonlight进程46934继续2K45/RKMPP/EGL，截图正常。GTX965M错误码0，Sunshine布局变化后仍创建h264_nvenc，最终编码占用10%。没有重启Windows/盒子、禁用显卡设备、卸载驱动或修改PVE/GPU直通。

| DISPLAY4 / Virtual Display Driver | 主屏，2560×1440@60，坐标0,0 | 保留原模式和主屏身份，唯一活动输出 |
|
||||
| DISPLAY1 / Microsoft Basic Display Adapter | 扩展屏，2560×1440@64，坐标-1024,1440 | 从Windows桌面布局停用 |
|
||||
| DISPLAY2 / NVIDIA GTX965M直接输出 | 原本未激活 | 保持未激活；GPU本身仍正常用于硬件编码 |
|
||||
|
||||
这里的“停用”仅指显示输出不参与Windows扩展桌面。设备管理器仍保留显示适配器，Windows设置也可能列出未连接的输出，不能将此操作说成卸载了多余显卡或移除了所有显示设备条目。
|
||||
|
||||
本轮VDD编号已是DISPLAY4，早先DISPLAY3记录不能用于写死设备号。工具按唯一活动VDD动态选择，并在修改前强制核对它已是2560×1440@60主屏，不满足条件不修改。
|
||||
|
||||
## 实现与验证
|
||||
|
||||
新增`tools/set-single-vdi-display.ps1`，Query只查询；Apply先保存设备身份、模式、主屏、布局为XML，使用ChangeDisplaySettingsEx逐项暂存，最后一次提交停用其他活动输出。申请为当前用户保存布局；不添加持续守护或额外登录任务。读回若不是唯一VDD主屏或模式改变，立即尝试恢复本次原布局。已有备份拒绝覆盖。
|
||||
|
||||
新增`tools/run-single-vdi-display.py`，通过已有VM100代理，在当前已登录用户会话运行一次性任务。任务已删除，最终`probe_task_present=False`。初次Query编译因缺少System.Xml引用失败，未执行显示修改；补齐引用后查询、应用、独立再次查询均成功。
|
||||
|
||||
当前状态已经验证；未通过重启/重新登录检验持久性，以避免中断用户使用。原2K登录脚本仍动态选择VDD，未改分辨率策略。盒子原配置、显示守护和串流参数未修改。
|
||||
|
||||
复核时误使用了会持续运行的`nvidia-smi encodersessions`，读取超时后已按进程及父命令精确停止本次监视子进程，再以一次性查询确认GPU健康；没有终止Sunshine或用户应用。Sunshine日志中的16:57音频端点错误早于本次显示调整，不是本次产生的新故障。
|
||||
|
||||
## 回退和证据
|
||||
|
||||
Windows原布局备份：`C:\ProgramData\VDI\single-display-20261103\before.xml`。
|
||||
|
||||
如需恢复，使用`python tools/run-single-vdi-display.py Restore`。恢复前核对显示设备名称、ID和注册表Key，身份变更时拒绝套用旧布局；本轮没有为演示回退再次打断当前单屏状态。
|
||||
|
||||
证据目录`docs/evidence/single-display-20261103/`包含before、apply、独立after-query、显卡/编码健康查询及实际2560×1440桌面截图。
