Subject: [Bug 201585] New: 144Hz 2560x1440 no longer works (caps at 120Hz)
Date: Thu, 01 Nov 2018 12:13:35 +0000	[thread overview]
Message-ID: <bug-201585-2300@https.bugzilla.kernel.org/> (raw)

https://bugzilla.kernel.org/show_bug.cgi?id=201585

            Bug ID: 201585
           Summary: 144Hz 2560x1440 no longer works (caps at 120Hz)
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.18
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: dan@acristinii.com
        Regression: No

> Using the default driver on Ubuntu 18.10 starting from the 4.18 kernel and
> up, results in the maximum frame rate being limited to 120Hz at 2560x1440.
> Downgrading to 4.17.19 increases it back to 144Hz.
