Hey notro, I'm facing a similar problem as this guy. http://raspberrypi.stackexchange.com/questions/37611/tft-kernel-module-not-loading-on-startup

Please could you help me out with it? Thank you

The screen becomes black after i load the drivers using modprobe, but doesn't display anything

I tried the steps you suggested, but no luck. Dmesg is showing me an error " Failed to start load kernel modules.

11ishan commented 8 years ago

The driver is loading properly, but the display isn't displaying anything, just a black screen as soon as i use modprobe

11ishan commented 8 years ago

And there is no fbtft.conf file in both locations

That's expected. This will put console 1 on /dev/fb1: con2fbmap 1 1

For X windows see: https://github.com/notro/fbtft/wiki/FBTFT-on-Raspian

If i edit the 99-fbturbo.conf file, i get an error saying failed to load kernel modules and later i get failed to start light display manager. During boot.

It seems fbtft drivers aren't compatible with RPi 3. The drivers start loading bcm2708_fb* various stuff like width, height etc.

Using journalctl -xn, i get the following error

Host name not found: 0.debian.pool Host name not found: 1.debian.pool Host name not found: 2.debian.pool Host name not found: 3.debian.pool

And, Host name not found: 0.debian.pool.ntp.org Host name not found: 1.debian.pool.ntp.org Host name not found: 2.debian.pool.ntp.org Host name not found: 3.debian.pool.ntp.org

I think you're better off asking in the Pi forums: https://www.raspberrypi.org/forums/viewforum.php?f=44

Ok. Thanks for helping me out.

Got the tft working!!! Thanks a lot for your help!!!

As it turns out the fbturbo config file was causing problems.
