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?

          Ellipse (mathématiques)

          Image
          Pour les articles homonymes, voir Ellipse. L'ellipse est le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante. Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...

          Quarter-circle Tiles

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 ...
