Bug ID: 105039 Summary: No 120hz with 4.15 kernel and DC enabled Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: unit73e@gmail.com
Since kernel 4.15 only 60hz is available. Forcing 120hz results in a blank screen. Only happens with DC enabled.

--- Comment #1 from Matthew Scheirer matt.scheirer@gmail.com --- Same issue with 4.15 / Mesa 17.3 / Xorg 1.19.6 on a 290 + Acer GN246HL. No DC the 144 / 120 / etc modes show up, DC only 60hz does.

--- Comment #2 from Marc Cousin cousinmarc@gmail.com --- I'm having a variant of this… cannot go over 1920x1080p
4.15, mesa 17.3, xorg 1.19.6, RX570. Deactivating DC makes resolutions available again.

--- Comment #3 from Harry Wentland harry.wentland@amd.com --- This should be fixed in our staging branches.
Can you try either the amd-staging-drm-next or drm-next-4.17-wip branch from Alex's repo. You can find it at https://cgit.freedesktop.org/~agd5f/linux/?h=amd-staging-drm-next

I confirmed this bug is fixed on amd-staging-drm-next branch (commit: 82beba2883b2). I'll test drm-next.4.17-wip later as well just to be sure. I assume this fix is going to be in kernel 4.16 (or already is)?
BTW I really like what AMD is doing regarding Linux. Thanks.

Finished testing drm-next-4.17-wip branch (commit: d0d4f398ddc0). This bug is solved in both branches.
Thanks. Marked as fixed.
