我有一些 iei 面板電腦，大約一分鐘後，螢幕就會黑屏。問題是我希望啟動螢幕保護程序，但不希望它使螢幕變黑。
X 由 nodm 啟動，並且 X 配置了 dpms 並禁用了螢幕保護程序，因此：
xxx@xxx-001:~$ xset -q
Keyboard Control:
auto repeat: on key click percent: 0 LED mask: 00000000

Font Path:

DPMS (Energy Star):
Standby: 7200 Suspend: 7200 Off: 14400
DPMS is Disabled
我還透過 grub 的核心選項禁用了 consoleblank：
xxx@xxx-001:~$ cat /sys/module/kernel/parameters/consoleblank
0
我嘗試了圍繞 setterm/issue 的其他一些東西，甚至是 kms，我還嘗試了一些其他內核
但似乎沒有什麼作用，總是一片空白。
有人看到我應該調查的線索嗎？
PS：我知道如何阻止螢幕空白/黑屏？和其他一些
編輯：我的問題來自 xscreensaver，如果我停用它，顯示器將按預期運行。但我在其他主機上使用相同的 .xscreensaver 並且它們表現正常，它們使用相同的核心和相同版本的 X11
