Which is the only one with high frame-rate, while the built-in one just runs at 60Hz. But I can show you how `optimus-manager` configures `/etc/X11/xorg.conf.d/10-optimus-manager.conf`. I'm attaching it. Probably the most relevant part is that it sets the iGPU `AccelMethod` to `none`. But without that the dual monitor setup just gets corrupted, probably due to the way frames are copied between the iGPU and the dGPU to support dual monitor setups. This is because the integrated display circuitry is attached to the iGPU, and the HDMI port to the dGPU. So they need to exchange frames. -- You are receiving this mail because: You are watching all bug changes.
