Hi, are you sure your GPU has enough resources to handle a dual-monitor setup plus the Darktable GUI plus OpenCL? It's a six years old device which was usually shipped with just 2 GB of dedicated video RAM.
I used to run a dual-monitor setup with a GeForce GTX950 2GB and had exactly the same problems. Running OpenCL or CUDA on NVIDIA cards comes with a lot of overhead, some desktop environments (looking at KDE and GNOME) also need a lot of graphics memory, and in the end 2 GB were usually not enough. regards, Simon Am 07.03.19 um 20:09 schrieb David Vincent-Jones: > Sorry for the lack of appropriate material ...
