Xserver not working with ARGB
 

I am having the following configuration

Xlib app-> Xserver -> Framebuffer(ARGB) . When I try to run some Xlib application
nothing is visible in the display.At the same time when I used dev2mem and punch
the data to the framebuffer memory, I could see the display without issue.

My observation.

When I dumb the memory and check I could see the alpha channel byte is 0,
That means they are switched off by default.
When I send the data using devmem I could see the alpha channel enabled.

My question

1.Is it possible that Xserver does not support alpha channel?.
2.If it supports how should I enable it.
3.Can someone point me to a application which can generate ARGB data.

Hi, and welcome here, at LQ!

I have no any idea about the answer, but I'm really sure you need to give us more details, like: OS, hardware, X version, video driver and how did you observe/test anything.
