How to resume GPU?


I am using OpenCL now. Sometimes when I make mistakes, for example I write data out of array bounds, there are so many noisy pixels on the screen. Usually I need to restart my linux box to fix it. Anything I can do without rebooting operation system?


You may try with killing/re-starting X only - Ctrl+Alt+Backspace should do the job.

Thanks. I logged out, but it didn’t work.
