Hi,
I've seen this problem discussed before on various mailinglists and forums,
but never any real solutions.=20
It seems to happen right after a video player, such as totem or mplayer, has
crashed. They might crash for different reasons, but the problem afterwards=
is
always the same.=20
Mplayer will f.ex give you the following error message:
X11 error: BadAccess (attempt to access private resource denied)
or if I try to start gvim:
(gvim:86376): Gdk-WARNING **: shmget failed: error 12 (Cannot allocate memo=
ry)
or totem:
The program 'totem' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadShmSeg (invalid shared segment parameter)'.
(Details: serial 31 error_code 166 request_code 147 minor_code 2)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
The only common thing with all these applications is gtk, though different
versions:
ldd `which mplayer`|grep tk
libgtk12.so.2 =3D> /usr/X11R6/lib/libgtk12.so.2 (0x289f2000)
ldd `which gvim` | grep tk
libgtk-x11-2.0.so.0 =3D> /usr/X11R6/lib/libgtk-x11-2.0.so.0 (0x2819=
7000)
ldd `which totem` | grep tk
libgtk-x11-2.0.so.0 =3D> /usr/X11R6/lib/libgtk-x11-2.0.so.0 (0x2848=
6000)
Seems to me that after a program such mplayer or totem crashes something is
left behind which blocks future programs from accessing certain resources. =
I'm
not a programmer, so that is my very limited analysis so far.
