Ubuntu & NVidia :: Dual screen setup and gnome-panel

Dual monitors, set up with nVidia TwinView in a way that the gnome-panel does not stretch across the whole desktop but is only on one monitor.

Now I want to add another panel on the second monitor, but if I create a new one, I can only add it to the primary display.

Solution:

• add a new panel as usual
• run gconf-editor and go to apps/panel/toplevels/panel_
• set the variable "monitor" from 0 to 1

And that's it!

Jumbo Frames on VMware ESX

From the Service Console:

1. Change the MTU on the vSwitch "esxcfg-vswitch -m 9000 "
2. Do an "esxcfg-vswitch -l" and a "esxcfg-nics -l" to make sure the vSwitch and the physical NICs associated with it are now set to an MTU of 9000.
3. Create the port group and add it to the vSwitch "esxcfg-vswitch -a "
4. Create a VMkernel interface and associated port group "esxcfg-vmknic -a -i -n -m 9000 "
5. Test it "vmkping -s 9000"

VMware machine on Linux over NTFS

When you get any VMware host software on Linux (Server or Workstation) running any guest on NTFS filesystem, you get ntfs-3g to 100% CPU usage on a regular basis.

This can be overiden by setting

• mainMem.useNamedFile=FALSE

in the .vmx definition file.

This gets 'mount.ntfs-3g' CPU usage back to manageable levels... 3~10%.
