Settings established either using libinput only or libinput+synaptics are lost every time I shut down or dock/undock. On undock I have to re-enable the built-in touch-pad, causing config to be lost for the usb touch-pad. I have to disable the built-in touch-pad (on the icon on the system tray) to make changes stick on the usb touch-pad. Experience is not smooth because every reboot all settings revert to default. Docked, Two screens mouse+usb touch-pad). With that pull-down list I would be able to config each touch-pad separately, as both have different parameters given the working config( Undocked, one screen with dell touch-pad.

I went back to my budgie desktop ( still have it updated and running on the same laptop in separate hard disk, just in case!! ) and both devices worked well simultaneously, even with libinput-gestures and gestures applications (You can set them to work on all devices).Īfter a trial and error process (not much documentation on this matter) I now know that depending on the xserver-xorg-input package installed, I get a basic screen settings ( libinput only) or a more comprehensive multiple tab config (libinput+synaptics) but still I am not able to enable the device pull-down list to work. First impression was that the new hardware was not recognized, even though it worked. Only the built-in from my laptop (Fibocom DLL07B0:01 044E:120B). Well, some things happened along the way:Īt the very beginning I did not see my usb touch-pad (HAILUCK CO.,LTD Usb Touch Touchpad) on the pull-down list of touchpad devices. Happy now in Kubuntu, I got a new USB touchpad I wanted to config it via KDE settings. I installed kubuntu looking for a better desktop, used budgie for a long while, but there was some issues.

Note: This issue does not apply to the Surface Pro 3 Docking Station.I am running Kubuntu 20.04 LTS on dell precision workstation M7520 which is a laptop.
If you experience issues when you connect passive video signal adapters to the Surface Dock, Microsoft recommends that you use active video signal converters instead. offers an active video signal converter for DVI monitors ( MDP2DVIS) and for HDMI monitors ( MDP2HD4KS). For more information on using adapters with MST hubs, refer to the following FAQ. Note: You should use passive adapters with MST hubs, except when you are converting from DisplayPort to VGA, since that type of conversion requires active adapters.
This is especially true if the computer has more than one DisplayPort or Mini DisplayPort connection. Check with your video card manufacturer to confirm which type of adapter you need for the setup that you would like to run. If you want to use multiple monitors with the same computer, you should use an active adapter because some video cards cannot run the maximum number of monitors while using DP++. Passive adapters are less expensive since they do not need to include additional chips. A quick way to check whether you can use a passive adapter is to see if the DisplayPort or Mini DisplayPort source has the DP++ symbol above it. The symbol is a D with a P inside of it, with two + signs to the left, one on top of the other.Īctive adapters use additional chips to make the conversion inside the adapter, regardless of whether the source supports DP++. This means that active adapters are more expensive than passive adapters. Thunderbolt ports support DP++ natively. To run multiple monitors from the same computer, refer to the Active Adapters section below. If the source supports dual-mode DisplayPort (also known as DP++), then you can use a passive adapter because the source can perform the conversion. If the source does not support DP++, then you need to use an active converter, which includes additional chips to perform the conversion. When you convert video from a source that uses DisplayPort or Mini DisplayPort to DVI or HDMI (for example, a computer to a monitor), you will need to consider the difference between passive and active adapters.
