Using Console Redirection
Answer
To set the server display to 256 colors:
• Right-click desktop.
• Select Properties.
• Click the Settings tab.
• Click the Advanced button.
• Click the Adapter tab.
• Click the List All Modes... button.
• Select, for example:1024x768, 256 Colors, 60 Hertz.
Reason for setting the server display to 256 colors:
The FPGA does color matching the best it can. However, sometimes
when a color is borderline, it displays differently than what you would
expect. If you can't see the color correctly, change the color depth to 256
colors on the managed system.
Select Linux for mouse acceleration on the vKVM window
pull-down menu.
Select a different operating system for mouse acceleration on the vKVM
window pull-down menu. Then, go back to the original operating system
to initialize the USB mouse device.
The Dell™ BIOS is emulating the mouse driver as a PS/2 mouse. By
design, the PS/2 mouse uses relative position for the mouse pointer,
which causes the lag in syncing. DRAC 4 has a USB mouse driver, which
allows absolute position and closer tracking of the mouse pointer. Even if
DRAC 4 passes the USB absolute mouse position to the Dell BIOS, the
BIOS emulation would convert it back to relative position and the
behavior would remain.
Virtual KVM requires the USB mouse driver, but the USB mouse driver
