[anna koukouraki]

For what i know, i for a moment or more couldnt control my pc and that that happened not once then firefox closed and my network manager was disconnected. i with root priviledges and rfkill fixed it twice and when i restarted firefox for searching what was the"linksys" open wireless connection that n.manager showed me ,i lost it.accrding to my point of view, i was being tracked. the point is that my desktop sharing options is totally disabled and i think through firefox.thats all folks.

morning. wpa continues to crash and i always fix it ..rfkill unblock wifi and restart network-manager and disable bluetooth. iwlist shows:phy0 bluetooth software disabled and then it fixes.i dont unterstand .what dependencies are between network-manager and bluetooth that make them not being enabled together?

[anna koukouraki (fganko-deactivatedaccount)]

i think problem solved. because i dont have a wpa crash and i work it for a while.this is what i did.
i had reached in a situation not to be able to open the system and then disconnected.thats what i did: 1,from synaptic i completely removed network-manager-gnome and pptp, updated ane upgraded 2, i wired the internet. 3 . i from the setup option disabled the wireless . booted and entered recovery mode and made the following steps : enable network, update grub, update and upgrade and then fix broken. then i installed network-manager and i had to remove some packages network that no needed. rebooted and did the same from the recovery twice. login in then gedit showed some strange thinks about lo connection.so it was the bluetooth as there was again a linksys connection open, i guess through bluetooth-which in every login reanabled itself-ALONE-.so from setup finally i disabled bluetooth and no linksys.thats it

Status changed to 'Confirmed' because the bug affects multiple users.

Hey everyone, I received this crash after messing around with /etc/nsswitch.conf I forgot the exact setup I had when the crash happened. My original setup was :

Original(no crash)l: #hosts: files myhostname mdns4_minimal [NOTFOUND=return] dns mdns4

Some change ->(crash) .

New line(no crash): hosts: files dns mdns4_minimal [NOTFOUND=return] dns mdns4

Now I'm not sure if this is what caused the initial crash or even that it fixed it but it's worth checking out and seems pretty coincidental.

[Kam Pow (kampowchicken)]

To try and reproduce this bug I went into nsswitch.conf and see which line caused this and by editing the line to:

hosts: files dns [NOTFOUND=return] dns

After restart and after I logged in, the screen was just black. So i had to go into the file and edit that out - restart and the system started up fine.
I made one more change to it and now the line is:

hosts: files dns

It seems to have made my connection alot more stable but I'm not going to try and mess around with it anymore, it seems that I may have some disk errors on my brand new hard drive. By the way, this is the conf file for debian avahi-daemon I think.

I get this crash every single time I open my laptop lid bringing it back from suspend. This happens on Lubuntu, Kubuntu, Ubuntu and Ubuntu-Gnome 13.10.

My device is an Dell N5050. It is supposedly Ubuntu certified (says Canonical), which is apparently a joke as all I ever get on Ubuntu is freaking errors on what is supposed to be stable builds?

Does Canonical even test this crap on their supposed certified devices?

Maybe if you idiots would quit fucking around with some pipe dream of having tablets and phones with Ubuntu on them (which is gauranteed to fail) maybe the forgotten about desktop could actually have some god damn QC done on it.

Reinstall "wpasuppliment" via synaptic package installer. That cured it for me.
