Virtual Console Problems...

Post by Marcus Hech » Thu, 06 Aug 1998 04:00:00


Running an older Debian release with kernel 2.0.30 I am running into a
problem with adding more virtual consoles. Currently I have the first 12
consoles running just fine (F1-F12). I toyed with the idea of adding the
secondary level of virtual consoles (using the left ALT key to get

After adding the appropriate lines (listed below) to the /etc/inittab I
get some strange reponses... Here is what I added (note that I have
since commented them out to get back to working order):

1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2  
3:23:respawn:/sbin/getty 38400 tty3  
4:23:respawn:/sbin/getty 38400 tty4  
5:23:respawn:/sbin/getty 38400 tty5  
6:23:respawn:/sbin/getty 38400 tty6  
7:23:respawn:/sbin/getty 38400 tty7  
8:23:respawn:/sbin/getty 38400 tty8  
9:23:respawn:/sbin/getty 38400 tty9  
10:23:respawn:/sbin/getty 38400 tty10
11:23:respawn:/sbin/getty 38400 tty11
12:23:respawn:/sbin/getty 38400 tty12
#13:23:respawn:/sbin/getty 38400 tty13
#14:23:respawn:/sbin/getty 38400 tty14
#15:23:respawn:/sbin/getty 38400 tty15
#16:23:respawn:/sbin/getty 38400 tty16
#17:23:respawn:/sbin/getty 38400 tty17
#18:23:respawn:/sbin/getty 38400 tty18
#19:23:respawn:/sbin/getty 38400 tty19
#20:23:respawn:/sbin/getty 38400 tty20
#21:23:respawn:/sbin/getty 38400 tty21
#22:23:respawn:/sbin/getty 38400 tty22
#23:23:respawn:/sbin/getty 38400 tty23
#24:23:respawn:/sbin/getty 38400 tty24

I then try both a "kill -HUP 1" and a "shutdown -r" to re-read the
inittab file. However, after logging into most of the virtual consoles
and going on about my business as usual - I eventually get the following

...login sucessful
bash: fork: Try again.
$ who
bash: fork: Try again.

Once it appears on one virtual console, the rest start showing the same
response. I can login as root just fine (not signs of any problems at
all), but not my normal user accounts. I also get the same error when I
telnet to the machine from another machine. Since commenting out the
last 12 tty's I haven't had any errors. I even tried just adding a
couple extra virtual consoles, with the same problems.

Is there something else that I need to be doing? Does anyone have any
experience with such a problem? Any suggestions and/or help would be
most sincerely appreciated!!

Thanks in advance,

1. Virtual Console Problem

I have recently installed the Slackware disks on my Gateway 486 50DX2.
Everything works fine except the virtual consoles.  When I switch to
another console using alt-F2, alt-F3 etc. I get the login prompt
but I also get random filled character blocks i.e. at random locations
on the display certain characters will be filled in completely white.
After a few switches between consoles the computer locks up completely
requiring a hard reset.  I suspect that the VGA memory is being written
into by some process but I really don't know where to start.  

There is nothing "unusual" about the machine.  Micronics ISA motherboard
(circa 1990) with Phoenix BIOS, ATI Grapphics Ultra Pro with 2MB, Linux
resides by itself on a Western Digital Caviar 2340 340MB HD.  The
motherboard has a 256KB secondary cache.

If anyone has any ideas what is wrong please let me know.  Thanks
