Public bug reported: Binary package hint: linux-image-generic
I have 2 NVIDIA Tesla C1060 video cards installed. Although they are called 'video cards', there is no video output on the cards. Actually, they are used for GPGPU, General-Purpose computation on Graphics Processing Units, or for computation just like CPUs. Since it seems that Ubuntu doesn't detect and install drivers for such cards properly, I installed drivers myself. Drivers are downloaded from http://www.nvidia.com/object/cuda_develop.html Everytime when linux kernel (packages linux-image-generic*, linux- headers*) upgrades, my driver installation is removed and I have to reinstall the driver. It seems the whole driver directory /proc/driver/nvidia/ was removed during kernel upgrade. Although it may not look like a real bug, I hope Ubuntu have better compatibility for GPGPU hardwares. Anyway, GPGPU is becoming popular very rapidly.
