I'm trying to get Nvidia drivers (415) + Cuda + prime select to run on my work Notebook. But every time the Intel graphicscard is selected, all symlinks are destroyed:

How to get nvidia-persistenced daemon to work properly?



https://bugs.launchpad.net/ubuntu/+source/nvidia-persistenced/+bug/1693123



But there only seems to be to two valid solutions:




  • Don't use Unity + GDM -> which I can't do, since we still deliver Software for 16.04 LTS, which needs to be tested in Unity

  • Use Nouveau or Intel drivers -> which isn't what i want to do since I want to use CUDA


So unless anyone knows something better I would create an alias which calls a wrapper script recreating all symlinks after switching.



Also does anybody know what the root cause of this problem is. Why are the symlinks delted?

      Ubuntu 17.10 boot stuck at message "Started NVIDIA Persistence Daemon" after installing nVidia 384.90



      How to get nvidia-persistenced daemon to work properly?



      https://bugs.launchpad.net/ubuntu/+source/nvidia-persistenced/+bug/1693123



      But there only seems to be to two valid solutions:




      • Don't use Unity + GDM -> which I can't do, since we still deliver Software for 16.04 LTS, which needs to be tested in Unity

      • Use Nouveau or Intel drivers -> which isn't what i want to do since I want to use CUDA


      So unless anyone knows something better I would create an alias which calls a wrapper script recreating all symlinks after switching.



      Also does anybody know what the root cause of this problem is. Why are the symlinks delted?

          Quarter-circle Tiles

          Image
          up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form? I think this problem has to do with finding the chance any given 2x2 square has a circle, but I can't find it. expected-value share | cite | improve this question asked Nov 20 at 15:03 6minecraftninja 1 2

          build a pushdown automaton that recognizes the reverse language of a given pushdown automaton?

          0 I think it's similiar to NFAs. I replace the finite states of the given automaton for start-states for my new automaton. I do it with $epsilon$ -transition from the start state to the actual finite states of the given automaton. The start state of the given automaton will be my accepting(finite) state of my new one. All transitions will be reversed of course to recognize the reversed word. But how do I have to change the stack of the pushdown automaton? That's tricky. formal-languages automata context-free-grammar share | cite | improve this question edited Nov 29 '18 at 14:20 joee
