A number of people trying to use gpm with XFree86-4.0 have
found their mouses not responding. According to a contributed
patch included with the latest gpm, the problem is that XFree86-4.0
now relies on SIGIO to detect mouse motion, and the Linux kernel does
not support SIGIO for FIFO's in the file system, such as /dev/gpmdata.
The contributed patch works around this problem by using a
pseudo-terminal for /dev/gpmdata instead of a FIFO in the file system,
but I think the correct fix is either to implement SIGIO for
FIFO's in Linux or use unix domain socket in the file system.
What I would like to know is: is there some reason (such as some
posix standard or something) why SIGIO does not work on file system
fifo's, or is it something that nobody has gotten around to impelementing?
