How can I reset the graphics card using KMS (vbetool post)?
You've needed to?
It's long time when I used the tool. After getting my nvidia card into undefined state (X server crash, relicts after playing with video overlay or directfb console etc.).
There's no direct equivalent to vbetool post. KMS drivers handle suspend/resume in the kernel. Some of them have lockup detection and have implemented GPU resets internally (which is far more complex than vbetool post); others don't and haven't.
I'm curious what you think the use case is.
Maybe the drivers are much better today. I just worry about removing functionality.
