Linux issues on Dell Inspiron 16 Plus 7620
I've had the Inspiron 16 Plus 7620 for about 2 years now, using Windows 11. It's a great laptop for the most part. However, today, I wanted to try Linux. I booted Ubuntu Live 24.04 from a thumb drive. While it did boot, the system was very unresponsive. The screen update lags constantly. Moving the mouse cursor barely works. When you try move it, it moves for a fraction of a second, then freezes in place. If you try to move it again, it "teleports" to the spot it should have been had it not frozen, moves for a fraction of a second again and once more freezes in place. Clicking on anything (if you can get the cursor to get there) takes several clicks to work. And the menus take forever to open/close. I tried an external USB mouse, but it has the same behavior.
I tried several Linux Live distros: Ubuntu 24.04, 22.04, the latest Manjaro Gnome, latest Manjaro KDE, latest Fedora Workstation. The issue is present in all of them. And the issue is only present when in Linux. Booting back to Windows 11, the system has no issues whatsoever.
I've tried restoring BIOS setting to default, as well as factory settings, but nothing helped. I'm currently running BIOS version 1.24.0.
The laptop specs:
i7 12700H
32 GB RAM
1 TB NVMe SSD
Intel Iris Xe Graphics / Nvidia RTX 3060
Has anyone experienced similar issues? Any ideas what could be causing this and how to fix it?
Thank you.

Thanks Legomastermind. Safe graphics was able to help me boot into Ubuntu Live mode and have it work for the installation, but once installed, the issue returned.
I was able to solve the problem by disabling Panel Self Refresh (PSR):
Edit file /etc/default/grub
Change line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
so that it looks like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0"
Save the file and then run this command:
sudo update-grub
After that reboot the computer. The issue should be gone.

Your best option is to contact the support forums for the individual Linux distribution. Users may have surmounted the problem you're seeing. Note that Dell has no Linux support for this model.

@ejn63 Which one? As explained in the original post, the issue is happening on several distros... However, I found that it mostly works with an older distro, Ubuntu 20.04. With that distro, I get none of the weird lag and glitches I get with more recent distros, but the touchpad doesn't work - I have to use an external USB mouse. From this it seems that the issue only affects distros with more recent Linux kernels.
Understood that Dell has no Linux support for this model - but I was hoping that people in the community has had success running Linux in this laptop and could share their stories here.

Start with Ubuntu 20 and see if someone has solved the touchpad driver problem. That's likely the best option until one of the newer distributions is updated with better support for your hardware.

I have an inspiron 16 plus 7630 and I can say I've had the same exact issues I've tried, debian 12, nyanarch, ubuntu 24, mint, and kali. none of them have worked. I'm still searching for a distro with a working touchpad.

I did more tests, the newest version of zorin with safe graphics was buttery smooth and i was able to use my touch pad. however testing zorin without safe graphics was as bad as the rest.

I just tested Ubuntu 24.04 with safe graphics and it works flawlessly.

I also had this problem, here's how it was solved: I installed an image of the new version of linux ubuntu 2025, created a virtual machine. I went into settings and turned off the "Integrity memory" option, then in the created virtual machine I entered the commands that are on the page 'https://www.linuxtechi.com/install-virtualbox-guest-additions-on-ubuntu /", Or the name of the "Ubuntu Guest Additions" page, you do all the commands in turn, just where you need to, enter your Linux version and that's it
