使用 XFCE，xscreensaver 唤醒并提示输入密码

Question

如果您仅在使用 VLC 时遇到此问题，请参阅此问题

当屏幕被屏蔽时，xscreensaver（版本 5.35）密码提示弹出，鼠标/触摸板没有任何移动。它只是出现，时间一到就闪烁（还有类似“ PAM 超时已取消”的消息），然后再次出现。然后重复循环。

我尝试重新安装它，但没有帮助。我在4.7.6-1-ARCH笔记本电脑上使用 Arch ( )。

这是日志消息（我xscreensaver:在所有行的开头删除了）。我没有触发的事件是ClientMessage在 10:48:47：

10:48:29: 0: grabbing keyboard on 0xd4... AlreadyGrabbed.
10:48:30: 0: grabbing keyboard on 0xd4... GrabSuccess.

我打印journalctl -p 3 -xb并得到了大量这样的行：

Oct 08 14:02:57 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): conversation failed
Oct 08 14:02:57 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): auth could not identify password for [xenohunter]
Oct 08 14:03:37 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): conversation failed
Oct 08 14:03:37 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): auth could not identify password for [xenohunter]
Oct 08 14:04:17 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): conversation failed
Oct 08 14:04:17 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): auth could not identify password for [xenohunter]
Oct 08 14:04:57 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): conversation failed
Oct 08 14:04:57 regulus xscreensaver[12913]: pam_unix(xscreensaver:auth): auth could not identify password for [xenohunter]

周期始终为 40 秒，这很可能是密码提示再次出现的时间。

我做evtest /dev/input/event${X}了 ${X} 是每个idfrom 的地方xinput list。另外，我做了与事件流一样id=0和id=1它是物理鼠标和键盘。当出现密码提示时，所有这些流都是空的。
