If you are experiencing mouse cursor jumping or erratic behavior when using a KVM (Keyboard, Video, Mouse) switch in Linux, it could be due to a number of factors.
One possible cause of this issue is the KVM switch itself. Some KVM switches may not work well with Linux systems, especially if they are not designed specifically for use with Linux. In this case, upgrading to a higher-quality KVM switch or using a different brand may help resolve the issue.
Another possible cause of this issue is the USB hub that is being used with the KVM switch. Some USB hubs may not work well with Linux systems, causing issues such as cursor jumping or erratic behavior. In this case, using a different USB hub or connecting the mouse directly to the computer may help resolve the issue.
It is also possible that the issue could be caused by a problem with the mouse itself. Some mice may not work well with Linux systems, especially if they are not designed specifically for use with Linux. In this case, upgrading to a higher-quality mouse or using a different brand may help resolve the issue.
Finally, the issue could be caused by a problem with the configuration of the Linux system itself. For example, if the mouse is configured to use a higher sensitivity setting, it may cause the cursor to jump or move erratically. Adjusting the mouse settings or consulting the documentation for your specific Linux system may help resolve the issue.
In general, it is a good idea to ensure that all hardware and software components are compatible with Linux before using them on a Linux system. This can help prevent issues such as cursor jumping or erratic behavior when using a KVM switch.
