Switching to external monitor causes extreme lag

Issues & Assistance
1

Hello,
I recently reinstalled my laptop with the latest garuda.
I am using an external monitor and once I switch the desktop to be shown only on my external monitor the whole system starts to lag severely, if I switch the output to an Extend monitor setup the problem disappears also if I use only my laptop monitor the problem is not present.
Any suggestions or ideas?

It looks like you unplugged the monitor before running the inxi so I can’t be certain, but one possible explanation would be if the iGPU is driving the external display instead of the dedicated GPU.

Take a look at the wiki for switching to a dedicated GPU and see if it helps:

Thank you for answering on this I was about to loose hope :slight_smile:
I did numerous tests and re-installs, and finally I settled at XFCE garuda DE and the problem persisted, I found on the forums this topic about Nvidia Frogging family drivers: Nvidia-all - Frogging-Family drivers (guide - installation)
And I tried to install them using the latest version and my problem was fixed.
The really odd scenario is that I also tried to install them on the KDE Lite version of garuda, and the problem was still there…
I switched to the ZEN kernel when I went on the XFCE de, not sure if the KDE Lite is installed by default with the lts kernel and zen kernel.
Here is an garuda-inxi output writing from my external monitor and with turned off build in monitor:
