Major screen corruption/sync issues with non-free NVIDIA driver

Support Graphics & Display
, ,
1

Since installing the latest NVIDIA drivers (version 455), I’ve had nothing but problems.

I followed the instructions on the Manjaro wiki but since switching from the nouveau driver, I get intermittent screen corruption (presenting as a block of “snow”) and the monitor dropping out of sync. I’ve confirmed this is not a hardware or cabling issue and the problem doesn’t appear when using the free driver. It usually only happens when the screen is “busy” (lots of windows or activity like scrolling). When the corruption is severe enough, it throws the sync out completely and the monitor goes in and out of sleep mode.

I am also noticing a significant amount of screen tearing within web browser windows which wasn’t evident before. Not sure if the two issues are related?

This is a new installation of Manjaro. The GPU is an NVIDIA Quadro T2000.

I have taken a photo to demonstrate the issue but this forum won’t allow me to include images or links.

Hello,

Please provide the information about your system as described here:

Have a look here for that:

Once you solve your Nvidia driver issue, to fix the tearing on KDE you can have a look at this Possible solution for Tearing (Nvidia proprietary)

But first things first, solve your broken drivers issue (when you’ll post more info people will be able to help).

Did you try drivers 450 or earlier? Maybe the 455 drivers still have bugs with some hardware?

6

Forgive me, I’m new to Manjaro (I came from Ubuntu). How would I roll back to a previous driver version?

7

In KDE Plasma, from the Application launcher (start menu, whatever you call it) you open the System Settings, or the Manjaro Settings (it will lead to same place in the end for where I’ll tell you to go), then you go in the Hardware Configuration menu, from here you right click, uninstall current drivers (455), when it’s done, you right click and install the drivers (450) (it will take time as it needs to download everything).

I’m suggesting that because when searching for a driver for your card on Nvidia website, they direct me to the 450 driver, not the 455 (though, 455 should support your card but it is recent so…).

PS: I went to Nvidia’s website ONLY for information, if you don’t know never downlaod and manually install drivers from website, always use the system integrated package manager or menus.

//EDIT: damn either you have slow internet, or you’re doing tests? I hope you didn’t break your system lol

So after a lot of testing last night and this morning, I can confirm that versions 450 and 455 of the non-free Nvida driver don’t work properly with the Quadro T2000 card. The same corruption is exhibited. Version 440 works fine.

I am aware never to install the package from Nvidia’s site. I had only been using the official repositories.

Welcome back :wave:
I was wondering if you broke the system or something :smiley:
Glad it is fixed for now. Sad to be held back on old drivers but if that works well, whatever :stuck_out_tongue:

10

Seems like this is still an issue with even the very latest version (460.39). Any ideas how I can once again roll back to 440?

11

440 is not officially supported anymore, you have legacy 390 (which I think is half broken but my thread about it didn’t seem to catch devs attention yet), or 460.

To go back to 440 you can follow instructions here [Support/How-To] Compile old/legacy Nvidia Proprietary Drivers [2020-12-30 Update Issue] but you will need to do it after every kernel update or else you’ll boot to black screen.

If your card is compatible I would suggest to try the 340 driver procedure listed in the thread above, has it has a DKMS installation, once you install it it will automatically trigger after every update, no manual intervention to do (you just need to make sure these package then do not get updated from AUR if you enabled the AUR, it is simple you need to add the nvidia packages to pamac blacklist).

Since beginning of this year, I was trying to migrate from Windows to Linux,
I have been facing the same artifacts as shown in the screenshot.
I tried out also older nvidia drivers, even the 440 driver (after patch applied).
It turns out that in my case the docking station could not keep up with the 30bit ColorDepth.
It doesn’t matter, which frequency or resolution, 30bit was too much. Windows was using 24bit
So for Linux I tried a Displayport to HDMI adapter which forces the connection back to 24bits.
Since then I got no scren corruption.
The nvidia driver or the linux kernel want maximum 30bit without considering the “weak” parts in between.

Unfortunately I can’t post links.
You can search on askubuntu with this keywords where I posted my artifact problem
