[unresolved] linux mint 12 crashes with ethernet D/C'd

[josh3366]

hey i am quite new to linux, and i have installed linux mint 12 x64 bit
now when i installed it from the live cd it required me to use a wired connection to the modem once i finished installing i rebboted as prompted then once i logged back into my account i unplugged the ethernet cable and about 30 seconds later the OS freezes but resumes once the ethernet cable is plugged back in (sometimes it doesn't)
and if i log in without it plugged in i can barely manage to log in before it freezes and i am using a notebook so i am not going to have it plugged in to the modem 24/7 i need a fix for this so i can be portable while using the notebook.

many thanks

p.s i originally posted this in the noob forums not quite sure where this should go but all help is greatly appreciated

Do not multipost the same topic/posting:

Add just one new topic/post in the appropriate section of this forum. Multiposting leads to confusion.

Please open terminal from the menu and run this command:

Code: Select all

inxi -N

It'll show you what network card / driver you have.

You mean you want to use wireless?

[josh3366]

no cos i can use and connect to the wireless network no prob, its just when i disconnect the ethernet cable linux mint freezes (can't use mouse/keyboard etc) and any applications running freeze and remain frozen

also if i boot up linux and login the freezing happens just after login and once the desktop icons load

[AlbertP]

Still, please run inxi -N and post the output as it also lists wired. Probably we can disable the wired network completely, then you use wireless only without freezing.

IF: eth0 state: up speed: 100 Mbps duplex: full mac: 00:26:6c:02:1b:c

If you want to disable the ethernet completely, please run:

Code: Select all

gksudo gedit /etc/modprobe.d/blacklist.conf

It'll open a text editor. Please add this on a blank line:

Code: Select all

blacklist atl1c

Then please reboot, and you won't have ethernet or ethernet related freezes anymore. If you want to use ethernet again you can remove the blacklist again (or put a # sign before it to make it non-functional) and then you'll be back in the old situation where ethernet works but freezes if there's no cable.

ok when i entered the code i keep getting this message after saving the file

[josh3366]

sorry for the double post but i just rebooted and unplugged the ethernet cable and the freezing still happened .... perhapse i did the blacklist line wrong there were other lines already written up in the text editor related to blacklisting so i pressed enter and typed the code out then saved it and thats when terminal displayed the error message above

[josh3366]

long story short LM12 needs me to have ethernet cable plugged in and crashes if i remove it so i tried disabling it using terminal and got this error

(gedit:3526): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.7IK2CW': No such file or directory

how do i fix this? and disable ethernet to stop crashes

[mads]

This is a harmless warning. To get rid of it, run

Code: Select all

sudo mkdir -p /root/.local/share
