[Solved] Connecting the external monitor via the Laptop's own display port instead of using displaylink on a D6000 dock, makes a difference. All previous problems (slow mouse, flicker, sudden blackouts) disappeared. 2022-mar-01
Hi I have an external monitor attached to my laptop. When I close the lid in order to run only on the external monitor, or simply If I put the laptop screen off, mouse and keyboard (both the usb and the internal ones) lag. It takes about 5 seconds to perform any instruction. I run this computer under linux. I have tried the following, without success: * Blacklist mouse from autosuspend * Enable wakeup for mouse * Disable autosuspend on all usb devices * Disable panel self refresh (psr) Any suggestion?
