以前没有这种情况～在终端中运行，返回：
The program 'cheese' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 50 error_code 11 request_code 140 minor_code 19)
(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.)
关掉compiz运行的话，一切正常。。
哪位大大知道是怎么回事？？帮帮忙～～
