Does anybody experience this issue and has a clue where it belongs to?
Issue:
1 - After waking up the laptop with darktable in darkroom mode and opencl previously activated,
when you tweak a module (filmic, for example) a warning message pops out saying that opencl was disabled. In terminal, clinfo shows no platform. The issue is well described here.
2 - After waking up the laptop without darktable in execution, clinfo correctly shows information about the gpu, and darktable, once started, has no issues and uses opencl as expected.
So, for now, I’ll make sure to close darktable before suspending the laptop until further notice that this issue has been solved (to be clearer, an issue that seems to have nothing to do with darktable, but nvidia driver or Ubuntu itself), but I’ll be glad to know more information about this.
