Default Re: shared memory pixmaps

Thank you for your advices.

We can use shared memory pixmaps by increasing the size of shared memory.
The size can be changed to 256MB by the following command;

# echo 268435456 > /proc/sys/kernel/shmmax

After that, the pixmaps argument of XShmQueryVersion function becomes true, so it means that we can use shared memory pixmaps.

The default size of shared memory is 32MB, and we have set the screen resolution 3840x2400. I thought that The default size might not be enough to the resolution.
