I got this bug where if I leave system AFK, then display always says that it doesn’t receive any signal from my PC. So I use this combination Ctrl+Alt+F4 and then instantly after, Ctrl+Alt+F3 and screen wakes up normally (some apps like fullscreen CounterStrike2 bugs out, but whatever).
Are there any easy fix for that, or should I hope for Plasma6.1 improvements?
I am a newbie and I think I have the same issue. Is your bug occurring when your PC goes to sleep? i.e. when your screen turns off?
Hi there,
Yea I have bigger problem with sleeping as well; I have simply disabled it for now. When PC waking up, Plasma enters glitched state which can be different every wake up. Either blinking, white wallpaper, imprintments, etc. So I simply disabled sleeping entirely.
Currently settings are:
On this post what I’m talking about are basically leaving PC as is, coming back after an hour or so, and seeing that HDMI monitor says that No Signal. Ctrl+Alt+F4 and Ctrl+Alt+F3 and it works again.
Weird. I think ball are onto nvidia drivers. Plasma6.1 will have explicit sync with nvidia and other nvidia graphics improvements, so I’m betting on it. Should arrive on Arch around June 19.
nVidia 3090 + HDMI 2.1 + LG C2 4K@120Hz VRR G-Sync enabled, gaming mode and low latency mode enabled on LG.
For sleep issues on nVidia:
https://wiki.archlinux.org/title/NVIDIA/Tips_and_tricks
Point 10.
Didn’t work, at least for me.
Shame, worked perfectly for me on an RTX3070.
systemctl enable nvidia-suspend.service
systemctl enable nvidia-hibernate.service
systemctl enable nvidia-resume.service
systemctl enable nvidia-persistenced.service
(i’m using systemd-boot)
sudo nano /etc/kernel/cmdline and appended to end: nvidia.NVreg_PreserveVideoMemoryAllocations=1 nvidia.NVreg_TemporaryFilePath=/var/tmp
LUKS+BTRFS. Reboot, then sleep and wake up, result:
All menus works, if you know where to blindly press them.
Ah alright. A bit different from my issue. Mine is definitely sleep related. After waking it up, my main monitor would go black. Only resolution was to turn the monitor off and on. Even rebooting to windows or removing cables didn’t work. I updated nvidia drivers (running a 3070) and it is slightly better and looks more like what you have in your last post but still borked. So no sleep for pc for now.
Will give this a shot. thanks
Yeh, systemd boot here - but I have some of this in a file not my cmdline - the method must of changed, at work so not near my machine. I wonder if LUKS is the issue? Have you a non-luks partition bigger than the vram to use instead?
Repartitioned via GParted to get unencrypted EXT4 100GiB at the end of my root drive and mounted it via fstab and tested it.
/dev/disk/by-uuid/REDACTED-REDACTED-REDACTED-REDACTED /var/nvibia ext4 rw,user,exec,nofail,noauto,x-systemd.automount 0 0
Changed /etc/kernel/cmdline :
..... nvidia_drm.modeset=1 nvidia.NVreg_PreserveVideoMemoryAllocations=1 nvidia.NVreg_TemporaryFilePath=/var/nvibia
Reboot, tested, and nothing changed.
RTX3090 has 24GiB of VRAM.
How can I check what module parameters are currently live on the system?
At least this one: https://serverfault.com/a/389965 doesn’t show my parameters applied for nvidia module (while it shows for other modules).
Unsure not at home, does lsmod work?
Could it be a monitor related issue? I have two monitors and only one of my monitors is giving me issues
It does, but doesn’t show what parameters are applied in live system.

Anyways, it’s kinda clear that nvidia drivers are writting something to this drive:
So after that I tried this:
Created /etc/modprobe.d/nvidia.conf
[v1n1@ttt modprobe.d]$ cat /etc/modprobe.d/nvidia.conf
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/nvibia
Rebooted. Tried to suspend. It worked for the first time. Woke it up and then suspended again. Now it kinda tried to suspend, display no signal (preparing to suspend), but fans didn’t stopped and after 20s, screen lit again like it would have woke up automatically (without fully finishing entering suspend state). Said wired network reconnected.
Rebooted again. Now it doesn’t manage to suspend at all (same thing as above), screen goes NoSignal for 20s and goes back up.
Not sure what about original issue of this post, will have to leave PC AFK to test it out. Maybe at least that, solved up.

This still doesn’t show my parameters applied for nvidia module (while it shows for other modules).
It strange that setting the same module parameters via /etc/kernel/cmdline works differently than creating /etc/modprobe.d/nvidia.conf.
So I tried the
systemctl enable nvidia-suspend.service
systemctl enable nvidia-hibernate.service
systemctl enable nvidia-resume.service
systemctl enable nvidia-persistenced.service
and I think I got a result but
I am not sure if I inputted or understood
sudo nano /etc/kernel/cmdline and appended to end: nvidia.NVreg_PreserveVideoMemoryAllocations=1 nvidia.NVreg_TemporaryFilePath=/var/tmp
Is that done on the terminal? I typed nvidia.NVreg_PreserveVideoMemoryAllocations=1 but got command not found.
Thanks for your patience. This is pretty new to me.
Yes.
If you have Kate program, you can type in terminal kate /etc/kernel/cmdline. Kate will open this file and when you save, admin (sudoers user) password will be asked.
/etc/kernel/cmdline file should be one liner.
Ok so I did this on kate and added
nvidia.NVreg_PreserveVideoMemoryAllocations=1 nvidia.NVreg_TemporaryFilePath=/var/tmp
underneath the line that appeared on Kate and saved. I restarted my pc tried to put it to sleep and hibernate but am still getting monitor issues on both my monitors. Am I missing any step?
Try
sudo touch /etc/modprobe.d/nvidia.conf
kate /etc/modprobe.d/nvidia.conf
This creates that file if it doesn’t exist and then opens it with kate.
and paste
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp
save it and then terminal sudo dracut-rebuild and reboot.
Works?
Yes! thank you very much! Where would be a good place to learn how you did what you just told me? Discovery? Archlinux wiki? Just want to understand what just happened better.
