I hope I am posting this to the correct area... I just purchased a StarTech SV211DPUA 2-port display port KVM switch. I'm using Ubuntu 18.04. I'm having an issue with the KVM where the mouse lags dramatically when using the KVM switch. When I mean lag, I mean I can move the mouse pointer and then the pointer pauses on its own for about 2 seconds and then it will allow me to use it again. The mouse I am using is a Logitech MX518. Is there a file somewhere (Xorg?) that I can try to tweak to see if I can fix this lag issue? Thanks ahead of time.

I've posted in the forum but thought I would ask here also. So, I am new to Ubuntu Server 18.04, netplan and .yaml. In the past using Ubuntu Server 16.04 I was able to create a pretty decent shell script to setup a static IP on a server in a post-installation setup. Is it not possible to script out the network configuration now that Ubuntu Server 18.04 is using netplan? I was trying to tweak my shell script to configure the writing to the .yaml file but it seems formatting is crucial when editing a .yaml file and I was not having much luck. It seems Ansible may possibly be a solution for this, possibly? But I've yet to master Ansible. Anyone else have any luck writing a script to configure a static IP using netplan and updating the .yaml file?

I received a CD from an vendor that has baby pictures on it. When I insert it into the drive, it does not mount. I know my CD-ROM works. How do I mount the CD within a terminal? This is what I see when I attempt a mount:

*sudo mount /dev/cdrom /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
Can only open '/dev/sr0' as read-only
NTFS signature is missing.
Failed to mount '/dev/sr0': Invalid argument
The device '/dev/sr0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?*

Here is the dmesg:
