The bug occurred with kernel version 3.10.0-498.el7.x86_64. Seems to be fixed in kernel-3.10.0-500.el7.x86_64, as it does not occur any more. |
Created attachment 1196368 [details] wrong mirroring with changed resolution Description of problem: There is wrong mirroring of two monitors, when the third is turned off. It does not mirror monitors, but sets them as primary & secondary and places them exactly on each other. Version-Release number of selected component (if applicable): xorg-x11-drv-nouveau-1.0.11-4.el7.x86_64 How reproducible: always Steps to Reproduce: 1.obtain at least 3 monitors and connect them to NVS 510 2.turn one of monitors off, but do not disconnect it 3.mirror other two monitors Actual results: Displays have written next to them "Primary", "Secondary" and "Off". It is possible to arrange displays, they are exactly overlapping each other. It is also possible to change their resolution, which affects mirroring [image in attachment]. Expected results: Every display should have written "Mirrored" next to it. It should not be possible to arrange displays or change its resolution in mirror mode.
