  • Can't get 144hz on new AMDGPU DC (Arch kernel 4.15)

    Hi,

    I just upgraded to kernel 4.15 and added the amdgpu.dc=1 parameter to my grub config, and somehow can't run any resolution at 144hz anymore. Any ideas? I'm running an RX580.

    thanks

    Before you report problems, use the latest available code and report to the kernel bug reporting system. Install and test my distribution from a fast usb memory stick or a disk partition, that has latest amdgpu driver kernel code. The Linux mainline kernels do have a partially implemented amdgpu driver, see the diff column at kernel org and compare to the ~agd5f/linux/log/?h=drm-next-4.17-wip kernel.
