 Posted: Sat Oct 20, 2012 1:45 pm Post subject: [solved]Konsole does not display prompt |
 |
|
i booted my system after serveral days, now i cannot open a prompt anymore ... i just get this: http://i.imgur.com/vFGWA.png xterm wont even start up
when i switch to the console (ctrl+alt+f1), login and the prompt works for every user. so the bash profiles are not the problem.
i have absolutely no clue what even the problem is.

First check out bash:
| Code: |
# ls -lh /bin/bash
-rwxr-xr-x 1 root root 733K Oct 20 05:13 /bin/bash |
if it looks fine, Then place something like this in /usr/local/bin/test.sh:
| Code: | #!/bin/bash
printenv>/tmp/envprint
/bin/bash |
and then check what command konsole is using on startup, if it's '/bin/bash' set
| Code: | | /usr/local/bin/test.sh |
as the 'command' under the general tab of 'configure current profile' under the settings menu.
That will dump your current environment variables into /tmp/envprint upon spawning a new tab of konsole and then kick off a bash session like normal. If it gets made, pastebin the contents of /tmp/envprint here.
EDIT: don't forget to make that script executable 
| Code: | | chmod +x /usr/local/bin/test.sh |

there are serveral bash processes running
| Code: |
# ps -A | grep bash
7777 tty1 00:00:00 bash
8171 ? 00:00:00 bash
8173 ? 00:00:00 bash
8187 ? 00:00:00 bash
8193 ? 00:00:00 bash
7789 tty2 00:00:00 bash
|
what is the possible reason that bash processes running on the xserver does not work? |

that doesn't look abnormal here's mine:
| Code: | # ps -A | grep bash
316 pts/3 00:00:00 bash
393 pts/5 00:00:00 bash
1208 pts/6 00:00:00 bash
2003 pts/0 00:00:00 bash
2112 pts/0 00:00:00 bash
2168 pts/0 00:00:00 bash
2292 pts/0 00:00:00 bash
2315 pts/1 00:00:00 bash
2374 pts/1 00:00:00 bash
6892 pts/4 00:00:00 bash
|
have you captured what the environment variables look like yet?
Possible reasons include,
the bash binary has incorrect permissions allowing root to spawn it but not you, that's why I asked for 'ls -lh; and not 'ps aux'
the incorrect command being set in konsole's profile, meaning it's not spawning bash
or generally the environmant variables are out of whack, test.sh was the solution that popped into mind
konsole could just be borked, have you tried tilda/terminator/urxvt?

Not sure why the pts is there, maybe just linux mint kernel here? I'm chrooted in from mint, as I am attempting to get an lvm root running on top of a dm-crypt
EDIT: anything funny in .bashrc or the like? |

i have re-emerged konsole after i had this problem. other terminals, yes. xterm does not start, i tried awesome window manager and can't pull a console as well, i just get a clock as a mouse pointer and nothing happened. i also tried ansi-term in emacs with /bin/bash and /bin/zsh both will not get me a command prompt. |

no not really, if .bashrc would be fucked up it does not make sense that i can login as normal user in when i am stepping away from x-server with ctrl+alt+F1 |

Of note, bash at least was recognized from the #!/bin/bash, and it did execute that printenv and redirect the output into tmp. But it hangs afterward when giving you a prompt. Definitely weird, only thing I can think of is maybe try and trap any error output bash is giving off:
| Code: | #!/bin/bash
printenv>/tmp/envprint
/bin/bash 2>/tmp/basherrortrap |
I would think that Kosnole et al would be displaying errors if they were there, but you never know. Of note, '2>' over '2>&1' as I believe the latter would also prevent you from seeing the prompt (which I guess is also in the remote possible root problems basket in this scenario). |

 that's hilarious,
check
/etc/init.d/devfs
and /etc/runlevels/sysinit/devfs
here's the relevant lines from grepping around:
| Code: | # grep -R devpts /etc/*
/etc/init.d/devfs: "devpts /dev/pts 0755 ,gid=5,mode=0620 devpts" \
/etc/runlevels/sysinit/devfs: "devpts /dev/pts 0755 ,gid=5,mode=0620 devpts" \ |
I did prune a bit of the errors out, and the updatedb.conf entry (doubting that's the problem). |

you can update to 0.11.1 now. Only openRC 0.11 is affected.

I noticied some messages on boot:
* /dev/shm not mounted!
* /dev/devpts not mounted!

Strange you have to do this yourself, I thought the openrc ebuild took care of that? If not then a message is the least that can be done. |

| The sys-apps/openrc-0.11.2 ebuild also does not tell you, I think (I had just corrected it before updating). |

$ /sbin/rc-update -s |grep udev
udev | sysinit
udev-postmount | default
# mount | grep /dev
/dev/root on / type ext4 (rw,relatime,data=ordered)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime)
udev on /dev type tmpfs (rw,nosuid,relatime,size=10240k,mode=755)
/dev/sda1 on /boot type ext2 (rw,noatime,nodiratime)
the problem is: /dev is mount *after* (yet expected to be before) /dev/shm and /dev/pts (same as when i read the boot message)
devfs should start *after* (yet before) udev-mount when udev-mount is pull in automatically by dependency
$ grep dev-mount *
udev: need sysfs udev-mount
devfs: need dev-mount
udev-mount: provide dev-mount
it seems openrc dependency algorithm screws up again |
