A friend's 3B1 often boots up such that when he logs in he is on /dev/syscon rather than on /dev/w1. Similarly, windy won't work. It looks like the Window Manager is having problems, but the question is why. I checked his /etc/rc and /etc/inittab and they are both identical to mine. All the standard processes are listed with a ps, but the wmgr appears to use a suspicously low amount of CPU. Any ideas? Thanks... -- Jim G.

I've forgotten the details now, but SysV used to have a bug whereby it would misbehave if the syscon entry in the /dev directory occurred before the console entry. Do something like "od -c /dev" on both machines and compare the relative positions of console and syscon. To move the console to the beginning of the directory do something like this: ln firstentry temp rm firstentry # free up the first slot mv temp firstentry ln console console_temp # grab the first slot rm console mv console_temp console firstentry is whatever you find at the top of the list when you do the "od -c /dev". This is all just a guess, but earlier releases of SysV did really funky things with syscon and console. Richard

I don't think this is your problem. I've seen this on a couple of machines where for some reason (still unknown to me), /dev/syscon get's unlinked from the other two names. On my system... crw-rw-rw- 1 root sys 1, 0 Jan 1 1970 /dev/console ^ a total different device driver. crw-rw-rw- 3 root sys 7, 0 Jan 1 1970 /dev/syscon crw-rw-rw- 3 root sys 7, 0 Jan 1 1970 /dev/systty crw-rw-rw- 3 root sys 7, 0 Jan 1 1970 /dev/window ^ all linked together. So to make sure things are right, just do this: # ln /dev/window /dev/syscon # ln /dev/window /dev/systty This should solve your problems with the window manager... -Lenny -- Lenny Tropiano ICUS Software Systems [work] +1 (516) 582-5525 lenny@icus.islp.ny.us Telex: 154232428 ICUS [home] +1 (516) 968-8576 {talcott,boulder,hombre,pacbell,sbcs}!icus!lenny attmail!icus!lenny ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752
