The AMDGPU Boot Parameter (Most Common)If your Lenovo laptop features an AMD Ryzen processor, a known driver bug handling power savings causes random freezing.

Adding a specific argument to the GRUB bootloader stabilizes the GPU.

Open your terminal (Ctrl + Alt + T).

Run this command to edit the GRUB configuration file:

bash sudo nano /etc/default/grub

Look for the line that starts with GRUB_CMDLINE_LINUX_DEFAULT.

It usually looks like this:textGRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

Add amdgpu.dcdebugmask=0x12 inside the quotes.

It should now look like this:

textGRUB_CMDLINE_LINUX_DEFAULT=”quiet splash amdgpu.dcdebugmask=0x12″

If you have a Lenovo Legion or newer model and this specific value fails, users on the Linux Mint Forums noted that amdgpu.dcdebugmask=0x10 also works).

Save and exit: Press Ctrl + O, hit Enter, then press Ctrl + X.

Update GRUB to apply the changes:

bash sudo update-grub

Restart your laptop.
