GNU Screen: Send to Multiple Screens at Once?
There is a feature that I used in KDE's Konsole that I really miss when I'm on a non-GUI server. The ability to "broadcast" what I type to all open windows. That led me to wonder if this could be done with GNU screen (since it can do a whole lot of other cool stuff)? Basically, it would be really great if I could start a screen session, ssh into three or four servers that I plan to run identical commands on, then type in one windows while having that typing sent to all the other windows as well. So far the 'man' page and various tutorials I've found online do not indicate that this is possible. I'd like an answer that is certain...

Hello,
One of the things I like about screen is that it has a scrollback buffer, which if you go into the copy mode, will let you go back for a specified number of line. Is there a way to extend the number of scrollback lines in screen? I've looked thoroughly online and I could not find a... (2 Replies)

glutinitdisplaymode
UNTITLED
LOCAL UNTITLED
NAME
glutInitDisplayMode -- Set the window creation display mode.
LIBRARY
OpenGLUT - window
SYNOPSIS
#include <openglut.h>
void
glutInitDisplayMode(unsigned int displayMode);
PARAMETERS
displayMode Requested display mode bitmask.
DESCRIPTION
glutInitDisplayMode() allows you to control the mode for subsequent OpenGLUT windows.
Allowable displayMode is a combination of:
- GLUT_RGB
Red, green, blue framebuffer.
- GLUT_RGBA
Red, green, blue, alpha framebuffer.
- GLUT_INDEX
Indexed color framebuffer.
- GLUT_SINGLE
Single-buffered mode.
- GLUT_DOUBLE
Double-buffered mode.
- GLUT_ACCUM
Accumulation buffer.
- GLUT_ALPHA
Alpha channel.
- GLUT_DEPTH
Depth buffering.
- GLUT_STENCIL
Stencil buffering.
- GLUT_MULTISAMPLE
Multisampling mode. (not always available)
- GLUT_STEREO
Left and right framebuffers.
- GLUT_LUMINANCE
Greyscale color mode.
Additionally, the following experimental features are implemented:
- GLUT_OFFSCREEN
Offscreen windows are very much like onscreen windows that have been dragged off of the edge of the screen. The biggest issue is that off-
screen windows do not support subwindows. Other than that, onscreen windows that are dragged off of the edge may not store graphics that you
render (while GLUT_OFFSCREEN windows do), and there is no way to drag an offscreen window onscreen for user interaction.
- GLUT_BORDERLESS
Borderless windows are very experimental, and their precise behavior is not set in stone. See also glutCreateMenuWindow().
The following are defaults :
- GLUT_RGB
- GLUT_SINGLE
CAVEATS
Some display mode features were introduced by OpenGLUT.
Not all features or combinations of features are valid for all platforms.
There is no way to change the display mode of an open window.
BUGS
GLUT_OFFSCREEN windows do not work with nVidia cards/drivers. (Both Win32 and X11)
GLUT_BORDERLESS seems to vary by the window manager on X11, though twm (for example) performs very similarly to WIN32. But KDE's window
manager (for example) does not let you send keystrokes to borderless windows without OpenGLUT hacks.
