Somehow I stuffed up the post with all the relevant info. I've pasted it here again: ----------------------------------- >8 ---------------------------------------- DISPLAY wasn't the issue. To cut a long story short... I needed to update some stuff on buildroot. However, it's still not working properly. I had to add the attached patch to get it to work with the frame buffer device I'm using. Xfbdev runs fine now but when I execute xlogo, nothing is displayed on the screen. The part of the screen gets 'cleared' so I know that it writes something to /dev/fb0. The output of fbset -i: # fbset -i mode "240x128-158" # D: 5.000 MHz, H: 20.325 kHz, V: 157.560 Hz geometry 240 128 240 128 1 timings 200000 3 1 0 0 2 1 rgba 0/0,0/0,0/0,0/0 endmode Frame buffer device information: Name : DISP0 BG Address : 0x906b8000 Size : 4096 Type : PACKED PIXELS Visual : MONO01 XPanStep : 1 YPanStep : 1 YWrapStep : 0 LineLength : 32 Accelerator : No # ----------------------------------- >8 ---------------------------------------- I'm using Xfbdev because, this is for an embedded product and I want to keep things as small as possible. The framebuffer driver I'm using is for a monochrome LCD panel running on an iMX.25 based system (I tweaked the driver supplied by Freescale to suite our needs. Thanks. Dushara P.S. What is preferred on this ML top/bottom posts?

Could you explain in more detail what you are trying to do, include the output of fbset on your hardware and what framebuffer driver you are using? Xfbdev is not a nested server, don't see how setting DISPLAY would help. If you can, please strace Xfbdev and include that as well. I assume an IOCTL is failing though I don't see any detailed logs. Xfbdev is based on the kdrive X server, it doesn't have the same configuration or logging as Xorg servers do. Why do you need to use Xfbdev, does Xorg (fbdev driver) not work?
