My desktop computer has an AMD A6 5400 APU and an AMD Radeon HD 7450, OpenCL support and OPenCL Scheduling profile are available when I ran the Darktable application. But if I run this application on my Laptop which has an intel i5 and an AMD Radeon HD 7600 series I get "not available" for both OpenCL support and OPenCL Scheduling profile. I would appreciate any help with this frustrating problem.
