Hi folks,
I've come across the most frustrating problem that I can't seem to find
any information about anywhere.
Shared memory.
I'm not even sure what shared memory actually is, except that everything
X11 wants it. And nothing I run, it seems, is getting any of it. Doesn't
matter what program I run, at what stage in the computer's uptime,
always always always: Gdk-WARNING: shmget() failed, or, various IMLIB
errors pertaining to SHM.
Now, the only information I was able to find regarding SysV shared
memory and FreeBSD was a discussion group posting explaining how to
increase the max segment size, which I did in my kernel.
Here's some info:
bacchusrx% ipcs -M
shminfo:
shmmax: 67108864 (max shared memory segment size)
shmmin: 1 (min shared memory segment size)
shmmni: 4096 (max number of shared memory identifiers)
shmseg: 256 (max shared memory segments per process)
shmall: 1024 (max amount of shared memory in pages)
Also, I checked out this imlib thing and shared memory is all turned on
and fuzzy there, so I can't figure this one out.
Absolutely everything wants this shared memory stuff, but nobody seems
to be getting any... which I think is causing problems when I do
multimedia stuff as well...
I'm running FreeBSD 4.2 with XFree86 3.3.6 with GNOME 1.2 and
Enlightenment 0.16.4 or .5 I don't remember.
If I just type "ipcs" I get:
