There are    around about getting Ubuntu LTS working with Nvidia 960M cards. Given that there's no definitive answer, I want to offer the following: after testing several distros, Knoppix and Kali both worked without any problems.   So, my questions:    What is different about Ubuntu that Nvidia drivers don't work out of the box? More importantly, is there an easy way (for an end user) to import whatever's working into Ubuntu 16.04?   Edit: Here's what I tried:   Purged nvidia-* and reinstalled 364 drivers. Got login loop, followed answers  (chown, chmod, rm .Xauthority, and  /tmp) Reinstalled xorg and unity. Went to  and found the  version that works with my card (opted for the Long lived branch). Purged nvidia* (no dash, following a tip in a comment), and reinstalled 367 drivers. Purged nvidia*, reinstalled 370 drivers. Currently stuck at login loop, after following instructions from 2.
I installed or upgraded to Ubuntu 16.04, but I'm having some problems with my graphics card.   The display is blank The display flickers Items on the screen do not display correctly Certain programs complain of graphics issues The computer boots to low-graphics mode Your specific issue may not be here, but try the solutions described in the answers anyway.   This question is very broad, but each one of these issues likely has one solution.    If you are experiencing a login loop, check the last part of my answer.    If you experience one of the listed issues and have your own solution (mine didn't work, or there's a faster way), feel free to post another POLITE answer, describing your problem and how you fixed it.    Those attempting to install Ubuntu, please refer to the section titled: If you are unable to enter a TTY or are trying to install Ubuntu.
Any Info on Generalized Binomial and Exponential Series? I was reading Concrete Mathematics by Knuth et al. and on p. 200, it references the generalized binomial series $\mathcal B_t(z)$ and the generalized exponential series $\mathcal E_t(z)$, defined as $$\mathcal B_t(z)=\sum_{k\ge0}(tk)^{\underline{k-1}}\frac{z^k}{k!}\quad\text{and}\quad\mathcal E_t(z)=\sum_{k\ge0}(tk+1)^{k-1}\frac{z^k}{k!},$$ where $x^{\underline k}$ denotes the falling factorial. I was interested in the generalized binomial series because it satisfied the identity $$\frac{\mathcal B_t(z)^r}{1-t+t\mathcal B_t(z)^{-1}}=\sum_{k\ge0}\binom{tk+r}{k}z^k.$$ I've been trying to find a way to compute the sum $\sum_{n\le k\le m}\binom{tk+r}{k}$, so this seemed related. It seems that $\mathcal E_1(z)$ is also somewhat related to the Lambert $W$ function, though I might be wrong. Searching them up online didn't seem to get anywhere, and I just want to find more sources where I can learn about these functions. If anyone can find some resources, I'd appreciate it! How can I apply an effect when a player left-clicks/right-clicks with an item in hand? Is there a way so that I make make it when I left click/right click with a certain item it applies an effect? I know that you can apply attributes to wearing armor and things but I want it so when you use the item it applies an effect on your player.  For example, let's say I want something so that when I right click with a certain item (let's say an iron ingot that was given to me) I'll then have a jump boost for 10 seconds. So kinda like a potion in a way.  Is this possible with command blocks/commands/any mods? What is $\gcd(0,a)$, where $a$ is a positive integer? I have tried $\gcd(0,8)$ in a lot of online  gcd (or hcf) calculators, but some say $\gcd(0,8)=0$, some other gives $\gcd(0,8)=8$ and some others give $\gcd(0,8)=1$. So really which one of these is correct and why there are different conventions? Power series is locally normally convergent in its convergence radius $B(0,R)$ Why is Harry Potter a half-blood? Two domains (when SSL) on same directory Is it possible to plot a graph of any shape? In school, I have learnt to plot simple graphs such as $y=x^2$ followed by $y=x^3$.  A grade or two later, I learnt to plot other interesting graphs such as $y=1/x$, $y=\ln x$, $y=e^x$. I have also recently learnt about trigonometric graphs and circle equations. In the internet, I have seen users posting graphs of different shapes like a heart-shaped graph and a Batman logo-shaped graph. I am sure there are numerous more graphs that I have yet to see. Seeing that the graphs can be shaped into shapes like the Batman logo and a heart brings me to my question: Is it possible to plot a graph of any shape regardless of its complexity? Perhaps, shaped into an outline of a person or a landmark? Why or why not? Is there any good reason that an empty set of round brackets (parentheses) isn't valid for calling the default constructor in C++?

Add leading zeroes to number in Java? Is there a better way of getting this result? This function fails if num has more digits than digits, and I feel like it should be in the library somewhere (like Integer.toString(x,"%3d") or something)  static String intToString(int num, int digits) {     StringBuffer s = new StringBuffer(digits);     int zeroes = digits - (int) (Math.log(num) / Math.log(10)) - 1;      for (int i = 0; i &lt; zeroes; i++) {         s.append(0);     }     return s.append(num).toString(); } 2.8 Why are collections grayed out? How can I open them? I've bought Cup models from Internet.   When opening .blend file I get Blender's Interface changed. To avoid this I've unchecked "Load UI" on opening the file.   But now I cannot see the objects of the project (I can see and render them when opening the file and leaving "Load UI" checked).   "Collection 1" on the "Objects Panel" (Don't know if it is it's name). is grayed out.   cup-models.blend with LOAD UI:    cup-models.blend without LOAD UI:    Blender 2.8: Complicated FOR loop nesting. Having trouble cleaning up legacy code I am trying to tidy up some really bad legacy code from an old developer and I'm trying to get rid of these nested for loops. The code below shows what I'm currently working with. I've fixed this before with nested SOQL queries but nothing like this. How would this need to look to remove these for loops (except Trigger.New)? Would I use Maps? How would I do that?  map&lt;Id,SObject&gt; mapProperyIdBudDetail = util.GetObjFields(setPropertyId, 'Property'); map&lt;Id,SObject&gt; mapSpaceIdBudDetail = util.GetObjFields( PropertyMap.keyset(), 'Space');  for ( Lease__c l: Trigger.New ) {      if(mapProperyIdBudDetail.get(PropertyMap.get(l.space__c))!=null) {          lProperties = new List&lt;SObject&gt;{mapProperyIdBudDetail.get(PropertyMap.get(l.space__c))};              for ( SObject p: lProperties ) {                  for ( String fm: FieldMap.keyset() ) {                      if ( p.get(FieldMap.get(fm)) != Null) {                         l.put(fm,p.get(FieldMap.get(fm)));                     }                  }             }     } } What is the reason behind the multiple Spider-Man reboots?

I started this chapter sometimes ago and faced in front of a tough problem. At first I started considering cases. Case-I : The probability of getting 1 head.Case-II : The probability of getting 3 head and so on. But there are many cases. So how can I solved this . Please help me. Thank you!
