Closed 3togo closed 1 year ago

3togo commented 1 year ago

when I try to run the examples in cuda folder, all crashed with sudden closing while trying to open window.

eg. ./histogram Below is the gdb output

@3togo stack trace info from description is quite limited, Can you get anything else useful ? Perhaps try graphics examples from CUDA toolkit, that can help narrow down the issue - if it is forge or system issue. Usually, if window opening itself failed, in 99% of cases it is related to system setup.

changing prime-select setting from "on-demand" to "nvidia" will fix the problem.

sudo prime-select nvidia

p.s. it is not a must because some of my computers does not have any problems with forge when prime-select is set to "on demand" mode.
