NVIDIA Quadro 10000M (Lenovo W520): Updaing to Kubuntu 12.04LTS from 11.10


Problem when update Kubuntu 11.10 to Kubuntu 12.04LTS on Lenovo W520

When I updated the Kubuntu 11.10 to 12.04LTS, there were some problems I encountered.
  • I can not boot Linux anymore (Black screen with the cursor on top).
  • I can not even boot by the Kubuntu install disk (DVD).
There seemed two problems.
  • The install disk problem: it doesn't support NVIDIA Quadro 10000M card.
  • The Linux boot loader's entry address might be changed.

Solution

  • Setup BIOS: Graphics card to Integration Graphics (not Discrete card, not Optimus). Then you can boot from the boot DVD disk. Then do the  http://shitohichiumaya.blogspot.de/2012/01/dualboot-with-wde-whole-disk-encryption.html, "Dual boot set up from Windows 7 partition" section. You may want to delete the old boot loading entry, if so, please see "Delete the boot entry" below.
  • Install the NVIDIA driver from your package manager. There is 295.40 driver is there. This works for Quadro 10000M.
  • Switch back to Graphics card BIOS settings to "discrete graphics card".

Delete the boot entry

  • On Windows 7, open the command prompt. Use "bcdedit /v" command to see which boot entries are there. You can see the boot entry IDs.
  • Type: bcdedit /delete {BootEntryID}
  • Be careful of this command! This is a dangerous command. Don't remove the necessary entries.

Why A^{T}A is invertible? (2) Linear Algebra

Why A^{T}A has the inverse Let me explain why A^{T}A has the inverse, if the columns of A are independent. First, if a matrix is n by n, and all the columns are independent, then this is a square full rank matrix. Therefore, there is the inverse. So, the problem is when A is a m by n, rectangle matrix.  Strang's explanation is based on null space. Null space and column space are the fundamental of the linear algebra. This explanation is simple and clear. However, when I was a University student, I did not recall the explanation of the null space in my linear algebra class. Maybe I was careless. I regret that... Explanation based on null space This explanation is based on Strang's book. Column space and null space are the main characters. Let's start with this explanation. Assume  x  where x is in the null space of A .  The matrices ( A^{T} A ) and A share the null space as the following: This means, if x is in the null space of A , x is also in the null spa

Gauss's quote for positive, negative, and imaginary number

Recently I watched the following great videos about imaginary numbers by Welch Labs. https://youtu.be/T647CGsuOVU?list=PLiaHhY2iBX9g6KIvZ_703G3KJXapKkNaF I like this article about naming of math by Kalid Azad. https://betterexplained.com/articles/learning-tip-idea-name/ Both articles mentioned about Gauss, who suggested to use other names of positive, negative, and imaginary numbers. Gauss wrote these names are wrong and that is one of the reason people didn't get why negative times negative is positive, or, pure positive imaginary times pure positive imaginary is negative real number. I made a few videos about explaining why -1 * -1 = +1, too. Explanation: why -1 * -1 = +1 by pattern https://youtu.be/uD7JRdAzKP8 Explanation: why -1 * -1 = +1 by climbing a mountain https://youtu.be/uD7JRdAzKP8 But actually Gauss's insight is much powerful. The original is in the Gauß, Werke, Bd. 2, S. 178 . Hätte man +1, -1, √-1) nicht positiv, negative, imaginäre (oder gar um

Why parallelogram area is |ad-bc|?

Here is my question. The area of parallelogram is the difference of these two rectangles (red rectangle - blue rectangle). This is not intuitive for me. If you also think it is not so intuitive, you might interested in my slides. I try to explain this for hight school students. Slides:  A bit intuitive (for me) explanation of area of parallelogram  (to my site, external link) .
