My Windows 7 desktop complained the disk space usage is near to 90%. After checked my Ubuntu VM, its virtual disk expands to around 200G although it only contains around 100G data.

So I googled some posts which have instructions:

• Shrinking VM Disk Images
• How to Compact a VirtualBox Ubuntu Guest’s VDI file

After compacted the VDI file, my desktop has more 100G free space now.

Reboot the Ubuntu VM, and it shows a message:
mountall: disconnected from Plymouth

Google again. The swap partition is not mounted correctly. Use following command to check it:

free -m

The total of swap is 0.

Try some commands from “Mountall fails on startup“, then the swap is back and the message is gone.

Final step, there is a very large hiberfil.sys file and I let my desktop keep awake for a long time. I think I don’t need hibernation, so I disable it by following article, “How to disable and re-enable hibernation on a computer that is running Windows“.

My favorite text editor on Windows platform is Notepad++. For current project, a XQuery syntax highlighting is better than nothing.

You can find a post, “XQuery support in Notepad++ XQuery 1.0 and MarkLogic 4.1 update“, and download XQuery language definition file from a GitHub project – NotepadPlusPlus-XQuery.

This morning, I moved to a new cubicle which is on the same floor. Just spent 30 minutes to get it done. All I need is net connection and power to get desktop working. That’s it!

ha…I wrote “New seat” on Aug. 8.

Sometimes I need to paste codes in Lotus Notes for discussion. If the codes have syntax highlighting will be nice.

In NotePad++, there is a plugin called “NppExport” which can let you copy the code in the clipboard in RTF format.

In PuTTY, there is a option called “Paste to clipboard in RTF as well as plain text” in Windows -> Selection. Just check it!

Noticed the mic mute button doesn’t work on T410. Find a solution on askubuntu.com.

On T410, the step A shows following result after run amixer scontrols:

Simple mixer control 'Capture',0

In step C, the script lenovo-mutemic.sh will be modified to use ‘Capture’ for detecting the event.

The mic mute button works fine now, but it can not keep the status after reboot.
