--- Comment #15 from Alex Deucher <alexdeucher at gmail.com> --- Created attachment 112228 --> https://bugs.freedesktop.org/attachment.cgi?id=112228&action=edit add some debugging output Based on the timing for the 1920x1080 at 120 timing from your xorg log, it looks like it should be just under the switch limit. Can you apply the attached patch and switch to the problematic mode and then attach your dmesg output so I can see what's happening? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
