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. When I specify the format of the framebuffer (565) I could see the GUI in the screen but a convoluted data. But some GUI is shown. My observation. 1. When I dumb the memory and check I could see the alpha channel byte is 0, That means they are switched off by default. 2. 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.
