Description swjenkins 1998-11-22 23:13:40 UTC
I have _serious_ problems when trying to login on text console #1 (tty1). Here's an example: login: r Password: I try to login as root, but as soon as I type "r" it displays "Password:" and I haven't even hit enter! This problem only occurs on tty1. Other times, the ENTER key displays a new prompt but on the same line (no linefeed), like this: [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# Also, if I manage to get logged on on one of the bad tty's, I can't move around in vi; the movement keys just display the key character instead of moving it (ie, "j" go move down on line displays a "j" on the screen but doesn't move down a line). This leads me to believe its some kind of termcap problem. These problems occurs on any tty at random, but not always right away. Sometimes it does it immediately after booting; sometimes the system has been up for about 10 minutes and then the problem kicks in. It is very repeatable though. It also appears that it you flood the tty with input you can break it; try issuing one command after another with a bunch of ENTERS thrown in. Maybe I type too fast, but still this shouldn't happen. RH 4.2 & earlier never had these problems. I mentioned this at the the TCLUG installfest this past weekend but no one else seemed to have the problem. I know it's not hardware related because it does this on my laptop AND on my desktop. Plus another guy I know has the same problem on different hardware (all hardware is intel pentium based). All systems with the problem are running RH 5.1. At first we thought it might have been the updates, but my testing disproved that theory. Here's what I've tried, none of which fixed the problem: 1. clean install of RH 5.1, no updated rpm's applied (still broken) 2. clean install of RH 5.1 with updated rpm's applied (still broken) 3. clean install of RH 4.2 (system works ok here), upgrade to RH 5.1 (broken then) 4. tried recreating RH 5.1 boot disks and repeating above steps (still broke) 5. kill the shell or getty on the bad tty; still broke. If a shell was out there, now pressing ENTER displays "^M" and you can no longer send a true ENTER to get the PC to accept input. 6. "init q" to try to make init reput the getty out there; it issues a new getty but that one too is still broken. 7. rebooting system (both cold & warm); neither works. I had the ^M problem in the past with RH 3.03, 4.1, & 4.2 but only under this situation: a) boot system to initdefault (runlevel 3). b) init 1 for maintenance c) then init 3 -- now whatever tty you were using in single user, you couldn't send an ENTER; pressing ENTER just displayed ^M. This was not a serious problem because it was a rare situation and I just learned to avoid it. The problem with RH 5.1 is serious and cannot be avoided. The reason for my upgrade is to be able to install Oracle (requires glibc) plus try tostay current with the OS. Any help would greatly be appreciated. I'm posting this to bugzilla at redhat's site also.

Observed this too. The symptoms indicate hosed terminal settings on a tty (termio and friends). This may be caused by an application that has either crashed or been killed in a way that prevented it from resetting the termio settings. One can recover without a reboot from the problem by issuing "stty </dev/THETTY" from another tty, though.

Dave, can you verify this with the steps he suggests?

We cannot duplicate this problem on 5.2 and later.
