- Hi folks -
- Twice in the last week we've had what I consider a graphics
- pipeline problem. Basically events go like this:
-
- 1) Run program foo (uses GL)
- 2) Foo gets killed because the machine runs out of swap
- 3) Run foo again - get immediate "Segmentation fault (core dumped)"
- 4) Logout/login - gamma is screwed /usr/sbin/gamma dumps core in /
- etc. etc.
- 5) But unix/non-GL progams fork/exec and continue to run fine.
-
- I've tried many logical combinations of /usr/gfx/stopgfx,
- /usr/gfx/gfxinit and /usr/gfx/startgfx (but maybe not *all* combinations).
- as root from a real login and the tport login but this does not reset the
- graphics to a usable state. It's not up to me to debug the program foo, I
- just want my machine back :-(.
-
- Question -
-
- Is there a standard way to restart/reset the graphics subsystem
- without taking the machine down?
-
- We're running IRIX 4.0.5A...
