- Subject: Re-starting GEM
-
-
- OK, someone asked how to start/stop GEM without losing memory and such.
- Here is a method that works.
-
- I'm sure that everyone knows you can use CNTRL-ALT-C to kill GEM. If you
- started GEM from a SHELL, you get your shell back. You can sometimes run
- a GEM application from the shell after you've killed the GEM desktop.
- Since GEM has already initialized the program can still call GEM, however,
- sometimes tyhe screen manager or something gets left in a weird state.
-
- SO! Try the following. Boot into a shell that supports good job control.
- I found that sh03 whatever binary was not adequate (I think this is ash).
- Bash has funky problems on my console when I run NVDI, so I used TCSH.
- You run GEM in the background!! If TCSH doesn't suspend GEM for TTY input
- when you start pressing keys, then simply press CNTRL-ALT-Z to stop GEM.
- You will get the standard message about a stopped job. Type JOBS to get
- the job list. You can use your shell as long as you like now. To
- return to GEM, simply type FG 1 (or whatever job GEM is). To get back to
- the shell, SIGSTOP GEM again. This doesn't free the memory that GEM
- uses, but it's about as close as its gonna get without some really nasty hacks
- I think.
-
- Like I said, killing GEM and then running a GEM program later sometimes works,
- but you gotta be careful (perhaps doing a wind_update(BEG_MCNTL) or something
- before the new GEM program would help) as it sometimes fails to work
- properly. The sigstop method works just as well, although you need to redraw
- the screen with something (maybe you can write a GEM desk ACC that saves
- the screen and then SIGSTOPs GEM, when it wakes up it could restore the
- screen .. maybe?)
