Nvidia video tearing

[Moosetek13]

I did that with the same results.

Did you check that nVidia Settings was installed? If so, is it operational? If it's not operational, did you reboot? If you didn't reboot, do so, check nVidia Settings again then post back.

The Nvidia icon is not in the system tray like it was before. Is there another place I can find it?
Or, is there a way I can install it separately?

Yes, I did reboot.

[Moosetek13]

I installed the Nvidia Settings from Software Manager.
It does not start with bootup, and it has no option for switching between Intel and Nvidia like it did before.

With all due respect, I can't help you. You insist on doing things that I haven't asked for. I'm sorry, but I'm not prepared to restart this a third time.

Cheers.

You asked if I made sure the Nvidia Settings was installed, so I did that.
What do you want from me?

Sorry, but I'm trying.
I went through the terminal when Driver Manager didn't seem to be working. Then you said to purge and reinstall the drivers through the terminal, which I did.
The nVidia Settings did not come up, even after a reboot, so I installed it because you said to make sure they were installed. What was I supposed to do with those instructions?
???

I'm frustrated as well, and it's getting late. I'll come back tomorrow and see if you are willing to work with me a little more.
Perhaps I can follow your directions better with a fresh start.

Ok. I asked you to check if it was there, not install if it wasn't there. Let's continue.

I've done some additional research and it appears that there are long-standing issues with your machine (GL753VE) and its support for nVidia. You're going to either have to get BumbleBee running or not use the nVidia GPU at all.

I was happy to continue assisting you but with your system being Optimus-based, it's way out of my pay grade. If nobody else can assist you, I recommend a trip to the nVidia forums here: https://forums.geforce.com/

I've done all I can, sorry. My BumbleBee/Optimus skills are zero.

i don't know what the issue is now, your dkms status says nvidia is installed, but that's not a switcher between intel/nvidia
so what's the current issue? nvidia-settings can be run in Terminal or search the MENU for nvidia

[Moosetek13]

catweazel, I thank you for all the trouble you went through.

For now I have restored a previous snapshot of before I started trying to update the nVidia driver from 390.48, and everything is back to normal.
I have the nVidia Settings back to normal as well.

[trytip]

try this command in Terminal and test for screentear (the command is not permanent)

Code: Select all

nvidia-settings --assign CurrentMetaMode="$(nvidia-settings -q CurrentMetaMode -t|tr '\n' ' '|sed -e 's/.*:: \(.*\)/\1\n/g' -e 's/}/, ForceCompositionPipeline = On}/g')" > /dev/null

That seems to have helped.
In Netflix, both with the video tearing and the choppy audio. Maybe they were related.

Is there a way to make it permanent?

Although when I click your link I can see the tear still. To a great degree.

[trytip]

i didn't think it would work in cinnamon for some reason i don't have any tearing with nvidia-340 in cinnamon19 except when playing some games that have too many strobing lights
yes you can add the script to the startup: i'm not in cinnamon now hope you know how to add it to starup?

create a blank text file in your HOME and name it notear.sh copy the command save. then rightclick on it, properties and make it executable. go to cinnamon settings startup and add the script

i'll post more detailed for cinnamon if you are not able to add

[Moosetek13]

Actually, I spoke too soon. The tearing is still there. Sorry.

Maybe I should try to install the 340 drivers?

[trytip]

i couldn't tell you if your card can go with nvidia-340 i mean theoretically it can but you'll need to figure out how to manually install it since the driver manager will probably not offer you the nvidia-340 but i may be wrong. do you have that option?

i don't know why i have screentear. i never had it in any distro or desktop, only in cinnamon19 but even that only when i play games that have too many blinking lights and for some reason the command removes it.

i don't even use the command for notear. i'm sure there has to be a remedy but i don't have the hardware to test. i can suggest you install a mainline kernel, but you really need to have a Timeshift snapshot to go back to in case things go bad. i use the last kernel 4.17.17 from ukuu found out that kernel 4.18 destroys snapd, maybe they fixed it but haven't tried the latest.

maybe your driver update didn't work because you were using kernel 4.15.

on the other hand if you decide to install XFCE the tear should be gone in any driver and if not the command will surely remove it. it's what i use now. i installed XFCE on top of Cinnamon

While I was still looking around I came across this: https://www.pcsuggest.com/nvidia-optimus-ubuntu/

I'm pleased you're back to normal at least. If you can confirm that the nVidia driver is loaded with inxi -G then I can help you with the tearing, provided that the nVidia Settings application is working.

If I may ask...
What is all that telling you?

[roblm]

For laptops with Nvidia’s Optimus technology, to prevent tearing on the laptop’s screen when the Nvidia GPU is enabled, the kernel parameter nvidia-drm.modeset=1 needs to be used. Use this command to open the grub file:
xed admin:///etc/default/grub

Change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"

Then update grub and reboot: sudo update-grub; reboot

Running glxgears in the Terminal should show the framerate is the same as the monitor's refresh rate.

Roblm...

And it was really that simple?
Thank you so much!

It may be too early to tell, but it seems that the video tearing is gone.

I'm not gaming, just watching videos. But in Netflix and VLC I don't notice it any more.
Netflix was worse, and my connection where I'm at is none too good so I don't have a good data rate. But I'll let you know in the days to come if it really has fixed the problem.

Thank you.
