NVIDIA 그래 픽 카드 구동 에 불 러 오지 않 은 문제 - 완전히 해결 되 지 않 았 습 니 다.

lsmod | grep -i nvidia

nvidia 의 커 널 모듈 이 없 는 것 을 발견 하여 수 동 으로 불 러 옵 니 다.

sudo modprobe nvidia_352_uvm

운행 하 다.

nvidia-smi

보고서 에 그래 픽 드라이브 가 없습니다.

ls /dev/nvidia*

장치 가 없습니다.http://www.x.org/wiki/NVIDIAProprietaryDriver/

Another cause may be that the /dev/nvidia* device files may be missing. To recreate this files simply run this script (as root). It assumes your users who have GUI access are in group "video"):

for i in 0 1 2 3 4 5 6 7; do
  node="/dev/nvidia$i"
  rm -f $node
  mknod $node c 195 $i  || echo "mknod \"$node\""
  chmod 0660 $node      || echo "chmod \"$node\""
  chown :video $node    || echo "chown \"$node\""
done

node="/dev/nvidiactl"
rm -f $node
mknod $node c 195 255   || echo "mknod \"$node\""
chmod 0666 $node        || echo "chmod \"$node\""
chown :video $node      || echo "chown \"$node\""

Finally, the NVIDIA kernel module may print error messages indicating a problem -- to view these messages please check /var/log/messages, or wherever syslog is directed to place kernel messages. These messages are prepended with "NVRM". 

근 데 그 다음 에 cuda 밤 을 움 직 여도 구동 이 안 돼 요.

ls /dev/nvidia*

nvidia 없 음 발견uvm 는 그래 픽 인터페이스 에 들 어가 driver manager 를 열 었 는데 nvidia 의 그래 픽 드라이브 를 선택 한 것 을 발견 했다.그런데 다시 보 니 / dev 아래 에 nvidia 가 있 더 라 고요.uvm 노드, cuda 밤 재 운행 성공!!!
문제: kubuntu 를 설치 한 후 nvidia 그래 픽 카드 드라이브 를 불 러 오지 않 습 니 다. gpumanager 의 앞 뒤 는 다음 과 같 습 니 다. 이전 에는:
