Hi, every one!

I want to use LCD Framebuffer programming, but there seems little WIKI or demos provided.  

I read http://processors.wiki.ti.com/index.php/Omapl137_linux_lcd_driver#Demos_-_startx, but there is no demo. After configurating kernel and run "startx", errors occured as below:

X Window System Version 6.8.2
Release Date: 9 February 2005
X Protocol Version 11, Revision 0, Release 6.8.2
Build Operating System: MontaVista Linux [ELF] MontaVista Software, .
Current Operating System: Linux 192.168.1.100 2.6.18_pro500-da830_oml
Build Date: 10 March 2007
Before reporting problems, check http://wiki.X.Org
to make sure that you have the latest version.
Markers: (--) probed, (**) from config file, (==) default setting,
(++) from command line, (!!) notice, (II) informational,
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(==) Log file: "/var/log/Xorg.0.log", Time: Wed Aug 8 08:08:37 2018
(==) Using config file: "/etc/X11/xorg.conf"
(EE) FBDEV(0): FBIOPUT_VSCREENINFO: Invalid argument
(EE) FBDEV(0): Mode init failed

Fatal server error:
AddScreen/ScreenInit failed for driver 0

How to solve the problem and is there support for programming LCD?

    Can you paste your /etc/X11/xorg.conf?.
