Xserver doesn't show correctly the windows

O.S.: STLinux
kernel: 2.6.27_stm23_004-SPEAr600
platform: SPEAr600

Hi all,
I've connected a display LCD to SPEAr and i launched Xserver with startx command...
My file /usr/lib/X11/xinit launch "xclock" with this command:
xclock -geometry 50x50-1+1 -name orologio

but the windows of xclock appear rectangular instead of a square (50x50) ...
Something doesn't work correctly, infact, I've tried to resize the windows setting it in full scrren size and I discovered that the maximum dimension that is achived is about 800x280... In addition to this, I've noticed that another windows of "xterm" is not complitly visible: I can't see it in its full length...
My display has a resolution of 800x600 and i'm sure the driver is good because I checked framebuffer size and I've tried to write an immage directly on framebuffer (/dev/fb0) and It's perfect...
Maybe is a problem of configuration of Xorg , so I tried to set the correct "mode" as described at this link:
http://www.linuxquestions.org/questi...en-area-38350/
But when I looked for file:
/usr/bin/X11/xorg.conf
I didn't find it!
How can I set the correct size that X server need to use?

try 'whereis xorg.conf' and look under /etc/X11/xorg.conf instead of /usr/bin/xorg.conf

I looked in all filesystem but there is no file named "xorg.conf", maybe is another file to handle Xserver...
I read that startx command launches xinitrc, this file is located at:
/usr/lib/X11/xinit/xinitrc
and contains the following text:

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/usr/lib/X11/xinit/.Xresources
sysmodmap=/usr/lib/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then
xrdb -merge $sysresources
fi

if [ -f $sysmodmap ]; then
xmodmap $sysmodmap
fi

if [ -f $userresources ]; then
xrdb -merge $userresources
fi

if [ -f $usermodmap ]; then
xmodmap $usermodmap
fi

# start some nice programs
twm &
xclock -geometry 100x50-1+1 -name orologio &
xterm -geometry 80x20+494+51 -name pluto -bg lightblue -fg turquoise &
xclock -geometry 100x50+0+0 -name orologio2 -digital &
xsetroot -gray &
exec xterm -geometry 80x20+0+0 -name login

I found also Xresouces in /usr/lib/X11/xdm/Xresources, and it contain this code:

I didn't find Xmodmap, it doesn't exist!
I don't know what I need to change or modify, I'm pretty desperate...

install the manufacturer drivers for your video card as opposed to the ones that came with the distro. They are almost always better and more complete and fix a myriad of strange otherwise unexplainable video issues

I'm sorry, but I'm working on an embedded system and I haven't got a video card... My display is handled by PL110 LCD controller and I wrote the driver by myself..I'm pretty sure that It was written correctly, but I don't know how configure exactly X server... I've created a .xserverrc file in /root folder , I wrote within it this line:
X -screen 800x600x32 -dpi 83
Now, when I launch startx I can see all full screen! but... It doesn't appear good , I can't read the text in the window and I see two or three cursors of my mouse...
I've tried others option like these:
X :0 -screen 800x600x32/24 -dpi 83
X :0 -screen 800x600x24/32 -dpi 96
X :0 -screen 800x600x32 -dpi 96
X :0 -screen 800x600x32/32 -dpi 96
X :0 -screen 800x600x32 -dpi 96 -deferglyphs none -render color -rgba rgb
etc...
...but nothing changed!!!

it looks like you have a problem with the driver or with the lcd screen. Try connecting it to a newer screen as that one looks rather beaten up.
