When connecting an external monitor DELL (60FPS) via HDMI and disabling the notebook display, the screen becomes laggy.
When I use extend mode, the external monitor + notebook display does not have laggy, but disabling the notebook display the problem starts.

If i see this correctly, you have a NVIDIA GPU NVIDIA GeForce GTX 1650 (TU117-A) graphics chip.
What machine are you using?
Which Ubuntu version?
I assume you are running wayland.
I am also experiencing issues with stuttering and laggy performance under wayland. Also with a TU117 chip (Nvidia Quadro T2000). Running X11 instead of Wayland works without any lags.
@fhortner, I’m use:
Avell A52 HYB:
GPU| GeForce® GTX 1650 (4GB GDDR6) | |
CPU| Intel® Core™ i5-12450H Alder Lake - 3.3GHz, Turbo Max 4.4GHz 12MB cache | |
Memory| 16GB [2x 8GB - Dual Channel] Memory DDR4 (3200 MHZ) | |
Display|15.6" FHD WVA (1920x1080p) - 144Hz / Matte / Contrast: 800:1 / Brightness 250 cd/m² |
Ubuntu 22.04.2 LTS x86_64
To change the display I use this command:
xrandr --output eDP-1 --off --output HDMI-1-0 --auto
The system run by xorg:
Ok, so no wayland issue here.
I would understand if the extended mode would be laggy, due to different refresh rates. But external monitor alone being laggy is wired.
May I ask, are you experiencing something similar like this on your external monitor in extended mode?
Since updating the Nvidia driver to 5.25.78.01 I am experiencing a diagonal screen tearing on my external Monitor Thinkvision P27u running either via USB-C DP alt mode, HDMI or connected via Thunderbolt Workstation Dock Gen2 Display Port. Same issue with a or Dell S7271QS via HDMI or Display Port via Thunderbolt Workstation Dock Gen2.
Notebook: Thinkpad P1 Gen2
The GPU is a T2000
OS: Fedora 37
Drivers not working so far: 525.78.01, 525.85.05, 525.89.02
Last driver working: 525.60.11
I am e…
The same problem the laggy on the external monitor occurs in ubuntu without i3 (only when I use only the external monitor).
I work with the same monitor via a dock when I connect HDMI cable and connect usb-c on macbook pro. I do not have this problem when disabling macbook display.
So same issue on a completely different machine (macbook pro) without nvidia hardware?
Maybe the dock is the issue?
I do not use the dock on my Linux notebook, in macbook I don´t have any problem with an external monitor.
I understood that you have the issue on macbook when connected to dock via usb-c.
No, I’m sorry.
English is not my native language.
no worries ;)
I’m sorry I can not help solving the issue
No problem, I’ll try reinstalling nvidia drivers.
After reinstalling the Nvidia driver and testing configurations I found a solution:
When I use
on-demand mode and use only an external monitor the laggy starts.
But if using nvidia by prime-select the external monitor works correctly, great.
I did not understand because in
on-demand and use extend mode (external monitor + notebook display) the laggy is non-exists.
