That's nice to know.
Yes I can hook via ethernet to download needed packages

Hi

That link shows how to compile the driver for BCM4311 card. Yours is a different model. They may or may not work.

We have a couple of options. We can try to get you connected to the net from your root console and attempt the steps in that tutorial. For this i may need the IP address of your router. This is the internal IP address so there is no security issues. It depends on how your router is set up.

Or we can try to disable wireless on your system to let you boot into a graphical environment and try the steps there. I thought moving the drivers directory might have done that but it does not look like that was the case.

EDIT:

Before we attempt any of these i have just noticed your Ethernet connection is disabled from lshw. This may be a show stopper.

In the root console type

Code:

sudo ifconfig eth0 up

Then type

Code:

sudo lshw -C network

and check to see if the disabled word has gone.

Post back results.

Kind regards

That seemed to get it up.

I have attached a screenshot that includes my LAN IP (and a few typos

)

Hi

Excellent. Let's see if we can connect you to the Internet.

Plug a cable into your laptop and a spare LAN port on your router.

Then type

Code:

dhclient eth0

When it has finished chcek to see if you have an IP address, gateway and subnet mask. You can check these with

Code:

ifconfig

If that looks good then try to ping Googles nameserver

Code:

ping -c3 8.8.8.8

Last but not least try a lookup

Code:

nslookup www.google.com

Report back on success or failure.

Kind regards

I was able to ping both google.com and 8.8.8.8

Hi

Good !!! You have a fall back position where you can connect to the Internet.

Let's try to get you booting into a graphical environment. To do this let's try to disable the bcm drivers. We can always re enable them later. From the root console...

Code:

echo blacklist b43 >> /etc/modprobe.d/blacklist

Code:

echo blacklist bcma >> /etc/modprobe.d/blacklist

Then reboot. Can you log on normally ?

Kind regards

Unfortunately. It stalls after "disconnected from Plymouth"

I have attached the output.

Btw: I need to add nomodeset to the boot options otherwise the screen is just one garbled mess. As far as I know that shouldn't affect anything of the stuff we're trying out with the wireless though.

I need to go to bed now, but I hope we can catch on later.
Once again thanks a lot for taking your time to help me!

Hi

It's late here as well so tomorrow ?

I am subscribed to this thread so when ever is good for you.

EDIT: After a very quick glance at the output, wireless is not the only issue here.

Kind regards

Hi Matt.

Sorry for not getting back earlier. I had a crazy week where I unfortunately didn't have time to experiment with this.

I have toyed around with it today and I have been able to boot to the commandline in the normal boot up (not rescue mode). I found out that it was the "vt.handoff=7" option in grub that was the reason that I couldn't continue booting.
I do though still have to set it to nomodeset, otherwise it freezes during the boot.

I have tried to run startx, but I get a "no devices detected error". I have crawled the web to find a solution to get it working without luck. I would have tried to use the Nouveau driver, but since I'm using nomodeset, that seems to be out of the question.

I have attaached the dmesg output after boot, the Xorg log, xorg conf and a picture of where it freezes when I don't set nomodeset at boot. (I had to zip the dmesg since it was to big a text file)

BTW: I forgot to write that the wireless do actually work fine despite the error messages. I removed the blacklist, and I have no problem connecting to the web...
