How can I get X11 screen buffer (or how can I get X11 to write to /dev/fb0)
location: linuxexchange.com - date: January 1, 1970
I'm trying to get pixel data from my X11 instance, I've seen this thread (How do take a screenshot correctly with xlib?) and the double for loop is taking just too long for me (over a million loops, as the system I'm building requires the highest amount of efficiency possible, sitting around for 600 miliseconds is just not an option). Is there no way to just get a raw array of pixels to avoid the for loop? I know the XImage class has a "data" member which is supposed to contain all of the pixels, but the organizational system that it uses is foreign to me. Any help would be greatly appreciated! The best end game here would be for me to just be able to have X11 write directly to /dev/fb0
How to remove black bars (change screen position) on TV display using xrandr?
location: linuxquestions.com - date: December 24, 2012
I have an old laptop connected to a CRT TV using an S-Video cable. However, there appear black bars on the left, right, top, and bottom sides of the TV. Using Windows, I removed these black bars by using the Intel TV Wizard to zoom in the display and adjust the vertical/horizontal positions of the screen so that the black bars disappear. Is there any way to do something similar to this using xrandr in Ubuntu? I've tried using the --scale option, but this does something different.
x11 "split screen" on sony vaio picturebook pcgc1xd
location: linuxquestions.com - date: January 4, 2004
recently installed peanut linux on my vaio picturebook and have a problem with x11.
The resolution of the LCD is 1024x480. In console mode no prob, screen is centered so I have a "normal" view with some black space on both sides.
But switching to X11 I have a kind of horizontally split screen: in the upper third there' s the bottom of the desktop, then comes a black bar of about 40 pixel hight and then there' s the top of the desktop. The part that shows the bottom of the desktop also is split (but vertically).
In /etc/X11 there is a huge sample XF86Config. I copied the ModeLine "# 1024x480 for certain Vaios" to the "Monitor" section of my /etc/X11/XF86Config-4.
May it be a modeline problem? I tried some other modelines and resolutions (640x480), but there is always the black bar and the split screen....
Hope anybody can help.
Find screen resolution in X11
location: linuxquestions.com - date: September 14, 2006
I would like to create a script that will create xterms of a certain size depending on the screen resolution. I have not been able to find a way to get the screen resolution (other than by setting it in xorg.conf, etc...). Any suggestions?
Thank you in advance.

I have a modified zipit z2, running debian. I am trying to find a good wm/desktop that requires little memory and processor power, and not much screen real estate. Right now im using fluxbox, but i would prefer something that does not use the mouse so much. any suggestions?

how to get a screen pixel's color in x11
location: linuxexchange.com - date: July 8, 2013
I want to get the RGB value of the top/left pixel (0;0) of the whole x11 display.
what I've got so far:
Display *d = XOpenDisplay((char *) NULL);
image = XGetImage (d, RootWindow (d, DefaultScreen (d)), x, y, 1, 1, AllPlanes, XYPixmap);
c->pixel = XGetPixel (image, 0, 0);
XQueryColor (d, DefaultColormap(d, DefaultScreen (d)), c);
cout << c.red << " " << c.green << " " << c.blue << "\n";
but I need those values to be 0..255 or (0.00)..(1.00), while they look like 0..57825, which is no format I recognize.
also, copying the whole screen just to get one pixel is very slow. as this will be used in a speed-critical environment, I'd appreciate if someone knows a more performant way to do this. Maybe using XGetSubImage of a 1x1 size, but I'm very bad at x11 development and don't know how to implement that.
what shall I do?
