4. Running MGR

The only file required in an MGR installation is the server itself. That would give you terminal emulator windows with shells running in them and cutting and pasting with the mouse, but no nice clocks, extra fonts, fancy graphics, etc. Depending on options, a monochrome server needs about 200K of RAM plus dynamic space for windows, bitmaps, etc.

If /usr/mgr/bin is in your PATH, then just type "mgr" to start up. After enjoying the animated startup screen, press any key. When the hatched background and mouse pointer appear, hold down the left mouse button, highlight the "new window" menu item, and release the button. Then drag the mouse from corner to corner where you want a window to appear. The window will have your default shell running in it. Hold down the left mouse button over an existing window to see another menu for doing things to that window. Left-clicking on an obscured window raises it to the top. The menu you saw that pops-up over the empty background includes the quit command. For people with a two button mouse: press both buttons together to emulate the missing middle button used by some clients.

The quit submenu includes the "really quit" option, a suspend option which should only be used if you run a job-control shell, and a screen saver and locker option, which waits for you to type your login password when you come back to your machine.

When trying to run MGR, if you get:

can't find the screen

make sure you have a /dev entry for your display device, e.g. on a Sun /dev/bwtwo0. If not, as root cd to /dev, and type "MAKEDEV bwtwo0". Otherwise, you might need the -S/dev/bwtwo0 or (on Linux) the -S640x480 command line option when starting mgr. On Linux, you might also make sure that /usr/mgr/bin/mgr was installed setuid root.

can't find the mouse

make sure /dev/mouse exists, usually as a symbolic link to the real device name for your mouse. If you haven't permission to write in /dev, then something like a -m/dev/cua0 option can be given when starting mgr. Also, make sure you've supplied the right mouse protocol choice when you configured mgr. The mouse may speak Microsoft, even if that is not the brand name.

can't get a pty

make sure all of /dev/[tp]ty[pq]? are owned by root, mode 666, and all programs referenced with the "shell" option in your .mgrc startup file (if any) exist and are executable.

none but the default font

make sure MGR is looking in the right place for its fonts. Check the Configfile in the source or see whether a -f/usr/mgr/font option to mgr fixes the problem.

completely hung (not even the mouse track moves)

login to your machine from another terminal (or rlogin) and kill the mgr process. A buckey-Q key can quit MGR if the keyboard still works.

4.1 Applications not aware of MGR

Any tty-oriented application can be run in an MGR window without further ado. Screen-oriented applications using termcap or curses can get the correct number of lines and columns in the window by your using shape(1) to reshape the window or using set_termcap(1) to obtain the correct termcap entry.
