    Command:

    resizecons

    
    
    

    SYNOPSIS

           resizecons COLSxROWS
           resizecons -lines ROWS
    
    
    

    DESCRIPTION

           The  resizecons  command  tries to change the videomode of the console.
           There are several aspects to this: (a) the kernel must know  about  it,
           (b)  the hardware must know about it, (c) user programs must know about
           it, (d) the console font may have to be adapted.
    
           (a) The kernel is told about the  change  using  the  ioctl  VT_RESIZE.
           This causes the kernel to reallocate console screen memory for all vir-
           tual consoles, and might fail if there is not enough memory.  (In  that
           case,  try  to disallocate some virtual consoles first.)  If this ioctl
           succeeds, but a later step fails (e.g., because you do  not  have  root
           permissions), you may be left with a very messy screen.
    
           The  most  difficult  part  of  this is (b), since it requires detailed
           knowledge of the video card hardware, and the setting of numerous  reg-
           isters.  Only  changing  the  number  of  rows  is slightly easier, and
           resizecons will try to do that itself, when given  the  -lines  option.
           (Probably,  root  permission will be required.)  The command resizecons
           COLSxROWS will execute restoretextmode -r COLSxROWS (and hence requires
           that  you  have  svgalib  installed). Here COLSxROWS is a file that was
           created earlier by restoretextmode -w COLSxROWS.   Again,  either  root
           permissions are required, or restoretextmode has to be suid root.
    
           In order to deal with (c), resizecons does a 'stty rows ROWS cols COLS'
           for each active console (in the range tty0..tty15), and  sends  a  SIG-
           WINCH signal to selection if it finds the file /tmp/selection.pid.
    
           Finally, (d) is dealt with by executing a setfont command. Most likely,
           the wrong font is loaded, and you may want to do another setfont  your-
           self afterwards.
    
    
    

    BUGS

           resizecons  does  not  work  on  all hardware.  This command used to be
           called resize, but was renamed to avoid conflict with  another  command
           with the same name.
