Brand new to Elementary OS, but familiar to Linux overall.

I've downloaded Steam and Lutris for management. While downloading Lutris, I was asked to follow these directions:


To get the latest Nvidia drivers it is necessary to add the Proprietary GPU Drivers PPA:

sudo add-apt-repository ppa:graphics-drivers/ppa

Enable 32 bit architecture (if you haven't already):

sudo dpkg --add-architecture i386 

Update to refresh packages:

sudo apt update

Warning: Please ensure your graphics card is supported by the 450 driver before installing. 
For a list of supported GPUs click here: https://www.nvidia.com/Download/driverResults.aspx/163238/en-us

Install the 450 driver:
sudo apt install nvidia-driver-450

Install support for Vulkan API (will be functional only if you have a Vulkan capable GPU):
sudo apt install libvulkan1 libvulkan1:i386

Reboot to apply changes.

I have an RTX 2070 Super. Since I enabled support for Vulkan API, my system becomes sluggish (for lack of a better word) every 2 seconds. Even as I am typing this note, every 2 seconds the system slows down and then catches up.

I have tried installing the NVIDIA Driver v450 and 460, rebooting at every step of the way, and I'm still experiencing this issues.

I have also tried removing Vulkan support, and I'm still experiencing this issue.

Any help is extremely appreciated~

  • Took a look at /var/log$ tail -f Xorg.0.log, I found this happening every second: 2926.098] (--) NVIDIA(GPU-0): Sanyo Electric Co.,Ltd. SANYO LCD (DFP-2): connected [ 2926.098] (--) NVIDIA(GPU-0): Sanyo Electric Co.,Ltd. SANYO LCD (DFP-2): Internal TMDS [ 2926.098] (--) NVIDIA(GPU-0): Sanyo Electric Co.,Ltd. SANYO LCD (DFP-2): 600.0 MHz maximum pixel clock over and over again, which coincides with what I see on the monitor. I've removed this monitor and replaced it with another one, new one doesn't have this issue. Any ideas?
