Resolution is 320x240, device is touch-screen Hitachi 3.5" QVGA
TFT-LCD. This display was in my LPC3250 Phytec IAR Rapid Development
Kit (KPCM-040-IAR).
I'll take a look at directory that you've pointed, maybe will find
something that could help, thanks.

Dmitry, what is the resolution of the device you're trying to use?
There are patches on ltib to add support for specific resolutions, you might
need to add one for yours. Take a look at the xorg-server patch that is on
/opt/freescale/pkgs/

Hi Stuart,
I have touchscreen and tslib is enabled. Tried to build without tslib --
same result: running 'Xfbdev -nolisten tcp' with or without tslib gave same
result:
/*
address@hidden /root]# Xfbdev -nolisten tcp
Warning: mode not found, using default
error: Invalid argument
Fatal server error:
no screens found
*/
Executing 'Xfbdev -nolisten tcp -ac -mouse mouse -keybd keyboard -screen
240x320x32' gave same error too.
Nodes /dev/fb* I've checked -- they exist and terminal (non-X) output to the
touchscreen works fine.

Hi Dmitry,
Another thing to check is that if you don't have touch-screen that 'tslib'
is disabled in the configuration. If tslib is enabled it throws a switch in
the xorg-server spec file. This may explain the invalid argument.
Try running Xfbdev -nolisten tcp with no other args, the server is
supposed to be able to probe and find defaults.
Also check that you really have a /dev/fb* device node present.

Tried 320x240 and 24 bpp -- same result.
Kernel was built with FB suppord -- while loading, linux perfectly writes
boot messages on the screen and color Tux is shown there :)

Hi,
It seems like you don't pass the screen parameter to Xfbdev (it needs
the screen resolution and bpp mode)
# Xfbdev -nolisten tcp -ac -mouse mouse -keybd keyboard -screen
240x320x32

Hi Dmitry,
It's a guess but it looks as though your board has not been built with
frame buffer support in the kernel.
I'm not sure about the mode error. The only platform I've run on are an
old MAC G4 box using.
Regards, Stuart
