Problem: keyboard not working properly, i.e. Upper-Arrow key activates the screen-shot window.

Some of my favorate Linux tools at work:

(1) use `watch -d` whenever you want to monitor the change of some shell commands' output, i.e. use the following command to monitor the disk-sizes:

watch -d df -k

(2) `sar -d`: used to monitor the disk read/write

 

watch -d sar -dp 3

Pay attention to the following fields: rd_sec/s, wr_sec/s, await, %util. small await and %util tends to be good. [%util below %10 is a sign of in-memory I/O]

(3) top: after entering the `top` interface, press 'c', 'b', 'x', '1'(if you have multiple CPUs). your `top` screen will be very 'active' when your shell is running multi-process programs. you can split the resulting windows by using 'A', 'G', '-'.. read the man page.. ...More

Making a bootable USB drive for a Linux box is rather easy with UNetbootin, check it out...

Just make a quick note: the reason for slow internet connections with Ubuntu box is nothing but the DNS configuration: check openDNS right-bottom corner, i.e.: 208.67.222.222 and 208.67.220.220. Replace the Ubuntu default configurations, i.e. 192.168.1.1, with these two IPs, that's it. BTW. if you know your ISP's DNSs, then use those IPs instead. :-)
