User Questions
Q: Get system info such as processor speed etc
A: Goto "Ubuntu Software Center" and install: hardinfo (System Profiler and Benchmark) "System Monitor" on some systems has a tab that says "System" before the Processes, Resources, and File System tab. On my system there was no System tab so I had to install hardinfo.
Q: How to check for bad sectors on system from GUI
A: Goto "Disks" which is the program name you type into the Ubuntu search. Just type "disks." Once the Disks utility opens you should select your hard drive from the left pane. In the upper right corner of the interface is a gear icon that says "More actions" click that and choose SMART Data & Self-Tests (a feature available for any modern S.M.A.R.T. enabled IDE/SATA drive). This works with a drive having that technology and Ubuntu having it enabled. The "Overall Assessment will denote the number of bad sectors. Click "Start Self-test" to refresh. An Extended test may take about 10 minutes for a drive around 80-120gb.
To more thoroughly check for bad sectors and even mark them as bad you can drop to console. You can perfrom a read-only test while the fs is mounted.
$ sudo badblocks -v /dev/sda1
To mark the bad blocks so that Ubuntu doesnt use them...
write the location of the bad sectors into a file.
$ sudo badblocks /dev/sda > /home/user/badblocks
Feed the file into the FSCK command to mark these bad sectors as "unusable" sectors.
$ sudo fsck -l badblocks /dev/sda
A: An easy way to to go to Muon (add software) and install Smb4K. It is a versatile network discovery utility.
Q: Change desktop screen resolution in KDE Plasma 5?
A: Goto KMenu -> Settings -> System Settings and under "Hardware" choose "Display and Monitor" select "Display Configuration" which is an icon on the left. In the right pane, which looks very plain you will see a box labeled VGA with 3 small icons: back arrows, a star, and a box with green arrows pointing inwards. Click that third icon with the green arrows.
Q: How do I print to a PDF document from something like Libra Office?
A: Simply install and activate cups-pdf service. Here are the commands:
sudo apt-get install cups-pdf
Now when you choose to print from software you will see a PDF option. A PDF of the printed page will then be available under your home directory, in a sub-directory named PDF. /home/user/PDF
On a typical installation it is common for cups-pdf to already be installed. This creates a virtual PDF printer. To select cups-pdf as the default printer go to System Settings -> Hardware -> Printers
