LinuxQuestions.org - was given some commands to corrrect a network problem now i can't get in my computer

- - was given some commands to corrrect a network problem now i can't get in my computer (https://www.linuxquestions.org/questions/linux-mint-84/was-given-some-commands-to-corrrect-a-network-problem-now-i-cant-get-in-my-computer-4175424299/)

i ran the commands again

the first 2 were the same
ls -l /var/log/Xorg.0.log
sudo ls -l /var/log/Xorg*.0.log
-rw-r--r-- 1 root root 29749 Aug 29 14:12 /var/log/Xorg.0.log

the 3rd command
ls -l /var/log/Xorg*.0.log
about the same i ran it later
-r-w-r-- r-- 1 root root 3553 Aug 29 14.44 /var/log/Xorg.0.log

and the 4th did not find that service
lightdm: unrecognized service

Evo2 was correct that Linux Mint is 98% the same as Ubuntu, but I believe that lightdm is unique to Ubuntu (it's the Unity log-in screen).

You need the equivalent dm for Mint, but I use Ubuntu so I can't help you with that.

am I correct in assuming that DM means display manager ???...

I have seen messages before about MDM does that sound familiar and would that be something in the log ???

thanks,
Nate

MDM stands for "MDM Display Manager" :)

MDM is a new Display Manager, which code is based on GDM 2.20. It provides graphical configuration tools, themeability, remote, automatic and timed login, event scripting, language selection and it comes with more features than any other Display Manager currently available.

So does that quote mean anything to you and if so what do i do with that ???? insert it into the sudo service command?

Ok I tried it when i put in

Code:

sudo service mdm restart

it restarded alright and asked me for my login and then went black again when i entered both the login and password:......that makes me think i have the right display manager. but there is a setting somewhere ?

thanks again

Yes, DM means display manager (really, it is the login screen). MDM sounds about right as it could be "Mint Display Manager," but since I use Ubuntu, I couldn't tell you for sure.

Try the command again using mdm in place of lightdm.

Hi,

nice work, figuring out that mdm is what you needed to reastart.

Ok, now you need to find the correct Xorg.0.log file that corresponds to when mdm was restarted, you logged in and then X crashed. So, using those ls commands that you used earlier find the file and post it as an attachment. Please also consider posting the contents of your ~/.xsession-errors file.

Evo2.

MDM is actually named on the mint web site as "MDM Display Manager" . Maybe if i go back and check the capitalization of that or look in the log i do have for a reference to it and get it from that ????

I am really stumped in how to find that file that your asking for not the xsession errors but the specific file when x crashed ... u gave me commands that returned very close to the exact same results that were dates and and names and no list. I assume you want the specific xorg.log from the precice time that it crashed. i have forgotten what date that was maybe 4 days ago and how do i find that ??? I thought i was progressing but ..... brick wall now .... help?

thanks,
Nate

Hi,

the point is that you now know how to restart X and by logging in make it crash/lockup. So after doing that you can look at the log file and confirm from its timestamp that it should contain information related to that crash/lockup.

Evo2.

I don't know how much you guys could find on my problem as written but i thought i would let you see if you haven't already what it is that caused this. I was having trouble with 'network manager' and someone told me to download 'wicd' and i thought i would try it. as i wrote somewhere i was having really good success with it but i had to finally reboot and i never got back in. this is the instruction I got to download and install wicd . I am wondering if there is anything in this that may stand out that caused my problem of not being able to reboot. and then my plea for help at the end.

Code:

 # install wicd and dependencies

    sudo apt-get install wicd



    # lauch wicd tray icon, only needed now, not after reboot

    (wicd-gtk --tray </dev/null &>/dev/null &)



    # remove networkmanager and dependencies

    sudo apt-get --purge autoremove dnsmasq-base geoclue-ubuntu-geoip gir1.2-networkmanager-1.0 libnm-glib-vpn1 libnm-glib4 libnm-gtk-common libnm-gtk0 libnm-util2 libproxy1-plugin-networkmanager mobile-broadband-provider-info network-manager network-manager-gnome network-manager-pptp network-manager-pptp-gnome



    # kill networkmanager launched processes

    sudo killall dhclient

    sudo killall nm-applet





All done. Please open Menu > Internet > Wicd Network Manager, or the tray icon, and do a Disconnect followed by a Connect to re-enable your Internet connection.

I'm sorry! I did not see that you asked for my mint ver. I should have started with that !

Linux Mint 13 Maya Cinammon

[code]
Well, the commands i received from this thread are much appreciated. The commands worked . Everything looked fine after implementing them. However when i rebooted 3 no 4 consecuitive times i got
nothing
then the request for user and pass and then a black screen .
then on reboot with the shutoff button on the front of the computer i got a - or_
then i got the request for user and pass
then a message about a broken pipe
all of these produced a black screen after the pass and user were entered
i'm now on the 4? reboot with a black screen waiting ... been a while too ... wont wait longer.

Anyone know how i can get it back ????[/quote]

thanks,
Nate

I'm 65 yrs old and about to cry. It seems that nothing I tried that worked before works now . I must be putting in the wrong form of the commands. I have maticulously copied them all on paper and it seems it didn't translate ... I'm not giving up yet but i don't know why .. cause at this rate I'm not going to get it ...

It really seems to me that X is working but is set to a black screen but what do i know ... anyhow thanks for listening.

thanks,
Nate

Nate,
Have you tried doing some of the original steps in reverse? It's possible the packages you removed from the original tutorial took some dependencies away in order for your GUI to work. Re-installing those packages may resolve the problem of your GUI (probably not the network). If you install them and your GUI works again then we can help you work on simply disabling the software packages rather than removing them.

Code:

sudo apt-get install dnsmasq-base geoclue-ubuntu-geoip gir1.2-networkmanager-1.0 libnm-glib-vpn1 libnm-glib4 libnm-gtk-common libnm-gtk0 libnm-util2 libproxy1-plugin-networkmanager mobile-broadband-provider-info network-manager network-manager-gnome network-manager-pptp network-manager-pptp-gnome

Try that, reboot or restart X and see if that helps with the problem.

sag ... dinner time here .... sounds like a plan i'm gonna do it right after dinner ....

also did you notice the message i got right after the fatal error

Quote:

Fatal server error:
Server is already active for display 0
if this server is no longer running , Remove /tmp/.X0-lock
and start again dah dah dah

I tried that and i'm not really sure , but i think so, if i got that removed or not.
i got the server started long enough again to do the login then it went black again so same prolem unless i didn't remove the file.

thanks,
Nate

Sam?:
dont' know what this means but it didn't work i'm sure .. maybe i didnot put it in right .. I think i did though.

Code:

sudo apt-get install dnsmasq-base geoclue-ubuntu-geoip gir1.2-networkmanager-1.0 libnm-glib-vpn1 libnm-glib4 libnm-gtk-common libnm-gtk0 libnm-util2 libproxy1-plugin-networkmanager mobile-broadband-provider-info network-manager network-manager-gnome network-manager-pptp network-manager-pptp-gnome

this is the result of running that line
E: command line otion '1' [from-1.0] is not known

thanks,
Nate

That line that sam gave me stops on E:command line option '1'[from-1.0]is not known. so i modified it to eliminate the "-1.0" and it said it selected gir1.2 but it's searching for other things... can anyone tell me what edits other than the one i just tried would be appropriate or even if the one I did edit already is appropriate?

thanks,
Nate

i'm sorry and i much appreciate the fact that there has been a lot of work put into this problem by many people who have volunteered a lot of effort to help. However I have to get my computer back .... So I am going to reinstall and my next project will be on the command line and the usage of the terminal to accomplish tasks ... that was my problem here . I have to pull the monitor cord and plug it into the other computer everytime i want to get help because i could not use the txt mode properly .. I couldn't even use a txt browser which may be my next project .... I love this operating system though. I will have to reinstall now. thanks to all who have ut in the time i' sorry i have to resort to this drastic effort

thanks,
Nate
