我正在努力暂停在我的桌面上工作，但systemctl suspend都不起作用systemctl hybrid。
然后我尝试systemd-inhibit --list --mode=block：
WHO UID USER PID COMM WHAT WHY MODE
zyf 1000 zyf 4934 gsd-media-keys handle-power-key:handle-suspend-key:handle-hibernate-key GNOME handling keypresses block
1 inhibitors listed.
所以我直接终止了该进程。但是，暂停仍然不起作用。
消息没有提及暂停。
最后我尝试了一下pm-is-supported --suspend，但什么都没有输出。
这是我的inxi -F输出：

更新：pm-suspend现在可以了
我尝试了一下pm-suspend，dmesg 中出现了以下几行：
[ 4304.972923] PM: suspend entry (deep)
[ 4304.992580] printk: Suspending console(s) (use no_console_suspend to debug)
[ 4305.181498] NVRM: GPU 0000:26:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management Support' section in the driver README.
[ 4305.181502] nvidia 0000:26:00.0: PM: pci_pm_suspend(): nv_pmops_suspend+0x0/0x30 [nvidia] returns -5
[ 4305.181863] nvidia 0000:26:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1b0 returns -5
[ 4305.181870] nvidia 0000:26:00.0: PM: failed to suspend async: error -5
[ 4305.222188] PM: Some devices failed to suspend, or early wake event detected
[ 4307.412089] PM: suspend exit
然后我发现了这篇文章：https://bbs.archlinux.org/viewtopic.php?id=283875，这建议我编辑/etc/modprobe.d/nvidia-power-management.conf并删除以下行：
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/tmp/nvidia
重启后，pm-suspend运行良好，但都不pm-is-supported是systemctl suspend。
