oclHashcat* troubleshouting clGetDeviceIDs() -1

Problem

ERROR: clGetDeviceIDs() -1

Solution

  • Are you logged in as the user who has opened the X session?
  • Did you use “export DISPLAY=:0”?
  • Is your display manager configured correctly? (gdm example config: http://www.sch0.org/gdm.conf )
  • Did you use the recommended driver (for the oclHashcat version you use) mentioned on the download page?
