How do I fix video tearing

[jacatone]

Anyone know the command sequence to fix video tearing on an nvidia card?

jacatone@OptiPlex-755:~$ lspci -nn | egrep -i "3d|display|vga"
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation G98 [GeForce 8400 GS Rev. 2] [10de:06e4] (rev a1)

Did you install a driver for this card? If so, what one and where did you get it from?

[jacatone]

Downloaded a ppa for the nvidia drivers. Have an nvidia x settings icon but it won't open. Below is what I have now.

Don't know what the nouveau driver is? Here's the command output:

jacatone@OptiPlex-755:~$ inxi -G
Graphics:  Card: NVIDIA G98 [GeForce 8400 GS Rev. 2]
           Display Server: x11 (X.Org 1.19.6 )
           drivers: nouveau (unloaded: modesetting,fbdev,vesa)
           Resolution: 1920x1080@60.00hz
           OpenGL: renderer: NV98 version: 3.3 Mesa 18.0.5

looks like you are already using the nouveau driver....

found this...have not verified personally....

"8xxx series cards only work with 340.96 or lower version of nvidia drivers. To check what version is installed type:

nvidia-smi

If the driver is above 340.96, try to install an older driver. This particular ppa is good for auto removing and installing:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-340

Restart your PC."

you should see this option in the additional drivers screen...try it

hope this helps

The additional drivers window just shows a manually installed driver. Should I install this "nvidia-340" driver?

jacatone@OptiPlex-755:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Also found this NVIDIA driver since my install is 64-bit:

the 340 driver is recommended...try it....use the command sequence above...

After installing nvidia-340, my system runs much better, but how do I prevent the NVIDIA X Server Settings window from launching every time I boot up?
