ThinkPads are my go-to. I just got an X1 Carbon Gen 9 (i5, 16GB) for $350 and put Fedora on it after upgrading the SSD to 1TB. It’s a beautiful laptop.
Of course, there’s the tried and true T480. Love that thing, especially if you get the right display panel and touchpad upgrades. Swappable batteries, upgradeable RAM. Those laptops can be had for cheap on eBay. Also check r/hardwareswap or the Discord for ThinkPad deals.
XPS 13 units can do well with Linux, too. I’m just a ThinkPad fan.
I don’t know what to tell you. We need more information.
Are you on Nvidia, AMD, or Intel for your GPU? What other symptoms? Have you done any other research on this in your troubleshooting? What does your config file look like?
I ask because I have a ThinkPad on Fedora with Hyprland and it’s doing just fine. Like another commenter said, help us help you.
