Hello, I see a constant 30% CPU usage in this particular xorg process: /usr/lib/xorg/Xorg vt2 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3 With some perf I have found that most of the time is spent on: - 32,91% 32,65% [v…

The problem is greatly improved (the high CPU), but CPU usage is still higher (6-8%, vs. 2-3%) with no DE apps running with 1 or 2 external monitors enabled, than with none. Also, the ordering/assignment of displays is all messed up. If I set my laptop display as primary, the taskbar gets moved to…

I have a 5800h (AMD) + 3070 laptop, with mux. I only tested in hybrid mode (internal display = AMD, external displays = nV). I ran multiple glxgears, including with no frame rate cap, and several concurrently, and I don’t see any corruption. Interestingly, the instance running on the AMD driver, …

I’ve downloaded the latest driver 525.78.01 but no luck, still high usage 25-30%. nvidia-bug-report.log.gz (431.0 KB)

For me, after updating to 525.78.01 the CPU usage dropped to 3%-8%. That’s good, but still not acceptable. When using only dGPU or iGPU the CPU usage is around 0.3%. I hope this isuue will be fixed too. Also I’ve noticed a strange little issue. When I’m using external display with reverse PRIME set…

Finally, there is absolutely working flawlessly on Ubuntu 23.04 Daily build by using Wayland and the latest Nvidia Beta Drivers the problems that I had gotten so far are now gone in these current versions, the external monitor is not tearing anymore, about the Nvidia power usage is really low at idl…

I have the same issue as OP. Hybrid graphics. Nvidia and Intel. NVIDIA GeForce GTX 1070 Mobile Running Pop OS 20.10

It’s been fixed since Nvidia 525.78.01, I tested Nvidia 530.30 with the latest Linux kernel 6.2, Both Xorg and Wayland are now working perfectly fine, I tested on Ubuntu 23.04 Development Branch.

I have RTX 3060 laptop GPU. I installed the Nvidia driver from additional drivers. as you can see in the image [image] I have the version of 525.89.02 installed now which is newer than 525.78.01. However, I still have the problem of high CPU usage. As a workaround I am running on the power mode…

Like I said, the problems have gone fixed in the latest Ubuntu 23.04 it’s shipped with the latest Xorg and Wayland so you can have your external monitor without worrying excessive CPU usage. Let’s try to add the latest Nvidia graphics from the repo: sudo add-apt-repository ppa:graphics-drivers/pp…

I’ve just installed Nvidia 525.105.17 on my Ubuntu 22.04, the problem still continues. Should I upgrade to Ubuntu 23.04? It says it is not released officially yet.
