Dell E5400 Linux Drivers
My laptop works fine with Ubuntu 9.04, there is just one problem, when ever X shuts down (in example, if I am shutting down my laptop, there is a brief moment when X is down, and there is only text on the screen, before the progress bar kicks in, the screen flickers madly) I hope the this issue will be resolved either when Ubuntu 9.10 is released or if I change distro, I have tried the latest Arch, it worked fine, but with Ubuntu is just flickers. However During boot the screen works fine through BIOS and GRUB, so I do not think it is a lose connector.
The Dell Latitude E5450 laptop with the components described below has been awarded the status of certified pre-install for Ubuntu. Please note that for. This guide should give you a complete walk-through for getting Linux to run on the E5400 laptop or others from the Dell Latitude E series. It is focussed on.

I am thinking of switching to Fedora of openSUSE.
I suppose it is possible that the previous owner of the laptop placed a hold on the linux-image so it would never be updated. Crazy, I know, but I have seen worse! Let's check: sudo dpkg -get-selections grep linux-imageIf any are marked 'hold,' then let's fix it: echo 'linux-image-XXX install' sudo dpkg -set-selections.where XXX is the latest 3.16 you found, ideally 3.16.0-28-generic. Then update: sudo apt-get updateAnd reboot. Confirm you are now running the latest 14.10 kernel: uname -rNext, reinstall the Broadcom driver: sudo apt-get install -reinstall bcmwl-kernel-sourceIf nothing is held, then we have a bigger issue to unravel! Please show: sudo dpkg -s bcmwl-kernel-source head -n9 lsbrelease -dThanks. Network Manager will, by default, prefer the faster and more secure ethernet.
In your case, the ethernet is connected and has an IP address. If you detach the ethernet and wait a few moments for NM to see the change in state, can you click the NM icon and see networks? Actually, this is a trick question; we know you see networks! Wireless Access Points BTHomeHub2-Q7W8: Infra, Freq 2412 MHz, Rate 54 Mb/s, Strength 100 WPA WPA2 BTWiFi: Infra, Freq 2412 MHz, Rate 54 Mb/s, Strength 100 BTWiFi-with-FON: Infra, Freq 2412 MHz, Rate 54 Mb/s, Strength 100Can you click on your preferred network, supply the password and connect?
If not, what happens? Does it try and fail or smoke or spit sparks or whine like a baby?? I really don't see much wrong, that is, fixable there. Two things might be helpful to adjust: lib80211crypt: registered algorithm 'TKIP'I assume your router is set for WPA2-TKIP. TKIP is not as secure as AES and is often a bit troublesome for some Linux drivers. Check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP.
Second, if your router is capable of N speeds, I have better luck with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection.

Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router. Next, I see this: cfg80211: World regulatory domain updated: That big, fat blank there means no regulatory domain was set; a one-size-maybe-fits-all was used. I recommend that your regulatory domain be set explicitly. Find yours here: Set it permanently: gksudo gedit /etc/default/crdaUse nano or kate or leafpad if you don't have the text editor gedit. Change the last line to read: REGDOMAIN=ISOf course, substitute your country code if not Iceland. Proofread carefully, save and close the text editor.
Let's also see if we can see why NM isn't starting and running the wireless as expected. Nm-tool sudo dhclient wlan0dhclient is expected to fail if NM is installed correctly, but let's see if there are any interesting errors or other messages.
