I been having issues with the cheap hp gaming laptop with Linux, One CPU core runs at 100% no matter that do i tried masking and disabling stuff, changing the Network card, adding Ram, and some desktops like Gnome forks had issues as well, KDE, and Mate work fine but it looks like it maybe has a Firmware, Driver or a Kernel issue, so far i tested it with Fedora, Fedora rawhide, Ubuntu and Mint, I’m going to test Debian next.
The laptop i had issues with Windows 11 works fine. https://www.walmart.com/ip/HP-Victus-15-6-inch-FHD-144Hz-Gaming-Laptop-AMD-Ryzen-5-8645HS-NVIDIA-GeForce-RTX-4050-8GB-DDR4-512GB-SSD-Mica-Silver-2024/5395277312
Edit Only Gnome 3 forks have issues with the Nvidia Drivers i will retest it at a later date with a new install and one CPU thread runs at 100% with all DE’s and OSes but Windows 11.
Edit 2 I think i found the issue AMD APUs on some systems with Nvidia GPUs will spam the system the bug report i found said to disable the iGPU. also Gnome forks work fine i think it was my fault for not disabling secure boot.
If Gnome has issues but Plasma and Mate work fine, then it’s likely not firmware related, but rather a process in Gnome that’s using a core all the time. So find out what that process is, if it’s a common thing on Gnome and if it will finish if given enough time.
The CPU thread runs at 100% with all DE’s/OSes i tested so far and the Nvidia Drivers and Steam had bad issues with Gnome 3 forks, but work fine with Mate and KDE I even gave the Open Kernel Driver a ago before reinstalling a new OS with a a different DE.
topwould show you which process is actually using the cpu core.it does not is why i think it maybe firmware or Driver issues etc i will work on debugging it at a later date also it maybe jest bad hardware as well if not i’m not buying anything from HP.
