hiya i have been playing around with linux mint 14 and dual booting with windows 7. its a year old toshiba laptop. i have mate installed and everything worked right out of the box. the internet worked grand. i have installed a few things like fluxbox, chrome and whatever and then tried installing enlightenment via the software manager.

it seemed to install ok and i chose it from the menu the next time i logged in. i wasn't happy with the theme so i downloaded one off the net and tried installing it via enlightenment. the laptop crashed and gave me a segv error. i had to ctrl-alt-f1 and then go back with ctrl-alt-f7 and it gave me the error and let me exit. i logged back in with the mate option but now i have no internet. i load up firefox and chrome and they both can't resolve any addresses.

is there anything that i can do to check what is wrong with it? i did notice one time that when i was waiting to reboot the line

modem-manager[671] signal 15 caught

came up for a little while. would uninstalling enlightenment help me anyway?

thanks in advance

Enlightenment can be very fussy about themes. If the theme wasn't built for your precise version of E, it might not work right. I have had E17 freeze on me from a dodgy theme on Slackware (but it was Slackware--CTRL-ALT-BkSp and I was back at the command line, where I went back to Fluxbox and deleted the offending theme). It did not break the ethernet.

If this is a wireless connection, try booting to a wired connection to see whether this is a wireless-only issue. If it's a wired connection, test with a known-good cable just to make sure the cable itself might not have malfunctioned; it happens--sometimes stuff just wears out.

Also, drop to a terminal and post the contents of /etc/network/interfaces the output of ifconfig, being sure to surround it with "code" tags, which become available when you click the "Go Advanced" button to the right of the "Post Quick Reply" button at the bottom of the reply window.

What ethernet chipset(s) do you have?

YO breadbin; Have you read or tried any of this yet?
Read it all first and decide which way to go first.

Are your cable connections proper?
Do you get any hardware error messages in Windoze Device magnager? Something that caught my eye was memory...
Is your IProvider up and running or any outages.
Everthang ahhh read about maintaining and modifying Linux installations centers around not using anything that doesn't come from a certifiable actively maintained true to the faith repository for the specific distro and version which you are using or want to use. Doing so otherwise isn't for the faint of heart and likely to break thangz eventually...if not sooner
Now I'm not an expert but if it were me and it doesn't turn out to be something else I'd try to go back to the configuration which was working and that could be as simple as uninstalling the clandestine software from last installed going back and checking the results after each removal along the way. I don't use commandline enough to be of any help there but seems my demented mind is thinking there is a remove command "rm" but you have to know where you put the beast software//where it is exacly in the file system and exactly what it is called and there may be modifier tags which you have to add telling the system what needs to be done. And Best wait for others to chime in and compare answers otherwise it's trial and error. Someone else may do ya better but this is what I'd look at. I'm on Mint 15 and 16 each version has it's own unique paper cuts to deal with. What's nice about repository software is it can mostly be added and removed via GUI and dependencies are for most part right on. Did you check the repos in synaptic or software manager if enlightenment was or could be installed from there before doing an outside job? Now Mint 15 repo shows some enlightenment packages in there but not installed.
Earlier versions such as 14 might have had it already installed and reinstalling it from interent definitely could have broken something@#$%^&*(). In this case you may open synaptic and chose fix broken packages [edit -- fix broken packages]. No guarantees but worth a try...
Some days it's hard to remember my own name and where the bathroom is but the refrigerator always finds me!!! Sooooo I guess you'll have to make a decision based on what you learn. I'm getting a little confused at the moment but it might seem that if the downloaded Enlightenment was the culprit and it wasn't already installed then removing it and then going to it through repositories to get it might be a good choice. If I screwed this up just yell back and hollar at me gQQd! A few things to look at and troubleshoot with hope something works. Gluck%:]]SW

Hi,
I had problems with Mint wireless connections. use a wired connection, install wicd, uninstall network manager.
Now I just leave the wired connection because it is so much faster and more reliable than wireless !!!

================================================
Not sure why I got this. I had no problem with my network connections. Like you I use wired unless I'm using wifi for making free cellphone calls via GoogleVoice.
==================================================

@breadbin
I hope this will fix your problem.
Connect your computer using a utp-cable when it's possible.
Use your "root" account.
1) apt-get update
2) apt-get upgrade (this will upgrade all your system packages)

3) When problem still occurs!
You can check missing links by using "apt-get check enlightenment".
(check is a diagnostic tool; it updates the package cache and checks for broken dependencies.)

4) Not fixed yet!
Remove this package by using "apt-get purge enlightenment".
(purge is identical to remove except that packages are removed and
purged (any configuration files are deleted too).

5)Clean your cache by using
"apt-get clean"
(clean clears out the local repository of retrieved package files. It removes
everything but the lock file from /var/cache/apt/archives/ and
/var/cache/apt/archives/partial/. When APT is used as a dselect(1) method, clean
is run automatically. Those who do not use dselect will likely want to run apt-get
clean from time to time to free up disk space.)

At this stage enlightenment must be removed succesfuly.

6) Check your wireless.
Normaly after upgrading your system you must have full wireless connection if you had it before enlightenment installation.
I may sound silly but check your physical wireless button on your laptop.
Can you see your wireless light turned on? If so, ok no physical problem.


7) when no lights after switching your laptop button!
Some machines have settings in the bios. Check in bios wireless is enabled.
If it is not, enable it and safe settings.

8) Checking wireless adapter.
Issue "ifconfig" and your output must contain the wlan interface.
You don't see it try "ifconfig wlan0 up"

9)Nothing happens.
Try "/etc/init.d/networking restart"
You will see a error when it is unable to load your wireless.

Wireless issues can by quit difficult to solve.
I suggest google to find out this problem.
I hope this will help.
Btw, this is a nice diagnostic wireless tool available.
Here you can check your adapter itself.
Usage: iwlist [interface] scanning [essid NNN] [last]
[interface] frequency
[interface] channel
[interface] bitrate
[interface] rate
[interface] encryption
[interface] keys
[interface] power
[interface] txpower
[interface] retry
[interface] ap
[interface] accesspoints
[interface] peers
[interface] event
[interface] auth
[interface] wpakeys
[interface] genie
[interface] modulation

10) Last but not least.
Issue "cat /etc/network/interfaces".
I quess the wireless isn't seen here, only your loopback interface by default.

Feel free correcting it when I'm wrong inhere.
Boutje.

wow thanks for the replies!

i rebooted a few times and it didn't resolve the issue, then i rebooted into windows for a while and next time i was in linux, the internet was working fine. it is wifi btw and a realtek chipset. so i logged into enlightenment again to try and remove the theme and of course nearly straight away i got the segv error. then the internet was gone again. i'm in windows now and at least now i know what to do when i go back into linux.

@boutje i have updated all, and will use the "apt-get purge enlightenment" when i go back in. i don't have a dedicated button on the laptop but its working fine here in windows so not a physical problem

thanks all for the replies.

@breadbin
Ok, one more thing you can do.
This will exclude your diffuse problem "wireless versus englightenment".
Boot from a live cd or usb-stick same like your operating systeem.
Check if you can perform wifi internet connection.
If it works while using live cd than you have to remove enlightenment application and it's dependencies.
Restart your pc so changes can be written.
I think using englightenment is causing your problem
Let us know when you can resolve it.
Wish you success!

yeah i've given up on enlightenment for the time being unfortunately. i would like to use it but just with the crashing and internet problems it doesn't make sense. i installed it from within synaptic and its version 16.999 and enlightenment itself does tell me to update but how can i get a newer package than the one i have? or would i have to compile the source myself?

@breadbin
I think the best way is a full removal by apt-get purge englightenment.
Clean your system by apt-get clean.
Reïnstall englightenment using your terminal by apt-get install englightenment.
Than issue apt-get update followed by apt-get upgrade englightenment.
I hope this will work out.

Hi!
Don't know if this will do any good for a Ubuntu derivate as I'm on Aptosid (flavoured Debian Sid). But I had some trouble, too, getting wifi to work at first on an Acer laptop. I tried a lot of the iw*-commands (get root, then in a terminal press i-w-tab-tab: should show you all possibilities) but didn't get it to work properly. I think one of the problems was to get the interface up, the command was similar to the good old "ifconfig eth0 up" but the iwconfig manpage doesn't look promising. Maybe it was ifconfig, I don't have it installed on this machine (an older Toshiba laptop). Another problem was the syntax to configure the wifi card for my WLAN.
On both machines the ultimate solution did it: ceni. It's an aptosid/siduction perl script that sets up your wifi based on a (text terminal based) menu selection. As it's command-line only, it may be just what you want.
Here's some help for ceni: http://www.google.com/url?sa=t&rct=j...,d.Yms&cad=rja
Where to get it? Here are two lines from my /etc/apt/sources.list.d/aptosid.list:
deb ftp://debian.tu-bs.de/project/aptosid/debian/ sid main fix.main
deb-src ftp://debian.tu-bs.de/project/aptosid/debian/ sid main fix.main
