FreeBSD oleg.Apholina.marka.net.ua 3.3-STABLE FreeBSD 3.3-STABLE #131: Wed Oct 27 10:50:01 EEST 1999 root@oleg.Apholina.marka.net.ua:/usr/src/sys/compile/OLEG i386
>Description:
allscreens in rc.i386 have incorrect behaviour, if:
1. value for MAXCONS options in kernel configuration file lower than number of /dev/ttyv* files
2. allscreens in /etc/rc.conf are enabled: allscreens_flags="-m on", for example
On such circumstantions you will get
....
rc.i386 configuring syscons: keymap keychange cursor screen_map font8x16 blank_time
moused allscreens cannot open /dev/ttyv7: no such device or address
....
after reboot
or
3. enabled ttyv*-s number in /etc/ttys lower than MAXCONS or /dev/ttyv* files number
>How-To-Repeat:
Set 'allscreens_flags="-m on"' in /etc/rc.conf
Set MAXCONS=6 in /usr/src/sys/i386/conf/YOUR_KERNEL
config YOUR_KERNEL
cd ../../compile/YOUR_KERNEL
make depend
make all
make install
fastboot
...
rc.i386 configuring syscons: keymap keychange cursor screen_map font8x16 blank_time
moused allscreens cannot open /dev/ttyv7: no such device or address
.....
>Fix:
May be, this patch not solve all problems in this situation?
I dont now how to retrieve avalaible virtual consoles number from
kernel for correct patch :-(
