Ubuntu Remove Old Kernels

From this site: http://ubuntugenius.wordpress.com/2011/01/08/ubuntu-cleanup-how-to-remove-all-unused-linux-kernel-headers-images-and-modules/

Unless you have a totally fresh install of Ubuntu, you have probably noticed that each time you boot up, the GRUB boot menu lists a bunch of previous Linux kernels which you can boot into. While this can occasionally come in handy – like if you can’t boot into the new kernel after an upgrade – those previous kernels, images and modules are usually just wasting space. While you can go into Synaptic, search for all the bits and pieces of previous kernels, and mark them for removal, here is a much easier method. In a terminal, simply paste the following command, and it will remove all but the current kernel (if you’ve upgraded your system, or had an update with a new kernel, please reboot your machine before running this): dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge FreeGeek Laptop Broadcom Wifi Card FiAcer Aspire 5920 Headphones don't work

Two pieces of advice:

First, from here: http://askubuntu.com/questions/176134/headphones-dont-work-on-an-acer-aspire-5920g

I had the same problem on my Acer 5930g. Even though I plugged in the earphones I hear the sound both in the built in speakers and the headphones. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the commands below. gksudo gedit /etc/modprobe.d/alsa-base.conf and add in this line at the end options snd-hda-intel enable=1 index=0 model=auto then save and reboot.

If that doesn't work, try this to get extra settings in Alsamixer:

http://askubuntu.com/questions/135804/want-sound-only-to-headphones-when-it-plugged-in-and-in-speakers-else

As ALC1200 and ALC888 seem to be very similar (see this German Wiki Entry) you can try my solution for the Intel HDA ALC1200 on my Acer Aspire 5920 G laptop. After upgrading to Ubuntu 12.04 Precise Pangolin from 11.10 my speakers continued to output the sound when plugging in headphones. In 11.10 the speakers were muted automatically when a headphone was plugged in. I fixed it by adding a line to /etc/modprobe.d/alsa-base.conf : options snd-hda-intel model=auto probe_mask=1 Now I've got a lot more options/controls when running alsamixer. One is "Auto-Mute Mode". Set this to "Enabled" if it does not work out of the box. rmware Issue Solutions

Sony Vaio microphone issue

Sound card is RealTek ALC262

Onboard Mic not showing up in Sound > Input as a device. Microphone in MIC Jack will show up as a device. Neither will record without a horrible amount of hiss.

Possible solution here:

http://ubuntuforums.org/showthread.php?t=1515440

Start up a terminal (Applications > Accessories > Terminal) and add the following line to /etc/modprobe.d/alsa-base.conf like so:

  1. sudo nano /etc/modprobe.d/alsa-base.conf

Enter your password to proceed. At the end of the file, add the following line:

options snd-hda-intel model=toshiba-s06

Note: If you see B's in brackets, leave them out!

Reboot your machine, and the internal microphone should work. If it does not, start up a terminal (Applications > Accessories > Terminal) and start alsamixer (just type alsamixer and press enter). Check whether the Capture settings are correct (press F4 to see Capture settings, use sideways arrows to select a column and up/down arrows to modify the volume accordingly).

Note: if you activate the Mic setting in the Playback screen (press F3 or F5) then you might get annoying echo/feedback/whistling on your microphone, so leave that set to a low setting (zero works fine). MacBook White Sound Recording Issue

Laptop Build Issues Tips and Tricks

NDIS Wrapper – look for “unpacked” Windows driver (for wifi card, for example) (i.e. Not an .exe file, unless it's in part of a self-extracting file). Point NDIS Wrapper at the file and it translates the Windows file into an Ubuntu-readable file.

Ubuntu splash screen looks awful on boot – usually pixellated on part of the screen, or other video artifacts that spook customers – BUT once the desktop displays it looks and performs normally. Explanation: native drivers can't handle the splash screen video. Fix: edit the boot script

Edit /etc/default/grub
  1. In the 6th line of the script replace “splash” with “nomodeset”:

GRUB_CMDLINE_LINUX_DEFAULT - “quiet nomodeset”

  1. Run “sudo update-grub”.

This means the splash screen won't display, so it will look as if Ubuntu is not booting. It will, though. The screen will go all black, (then sometimes all white), then the mouse pointer will appear, and after that the desktop.

FreeGeek Laptop Broadcom Wifi Card Firmware Issue Solutions

From now on our default installation of Ubuntu 12.04 will blacklist the B43 Broadcom driver.

For laptops with a Broadcom Card:

  1. First try to replace the Broadcom card with an Intel card. If this works, skip the remainder of the steps listed below and proceed with Build and QC as you would normally. Some models of HP and Dell will refuse to boot or even allow you into BIOS with an “incompatible” wifi card: these models insist on a specific Broadcom wifi card. For these:
  2. Ensure the wifi card is installed and connected (the driver won't install properly unless it can “see” the card).
  3. Boot. Once Ubuntu has booted:
  4. Open a terminal (Ctrl+Alt+T) and install the Broadcom firmware:
  5. Type: sudo apt-get install b43-fwcutter firmware-b43-installer, and press Enter.
  6. . Then remove the B43 blacklist:
  7. Type cd /etc/modprobe.d and press Enter.
  8. Type sudo rm blacklist-b43.conf and press Enter. Close the terminal (Alt+F4).
  9. . Wifi should work. If it does not work immediately, reboot.
  10. In any case, reboot to test that it boots properly and does not stall in the middle of the boot.

For any machines that are hanging on boot – HP and/or Dell models where we tried installing the Broadcom firmware using the Additional Drivers application, do this:

  1. Boot into GRUB. (Hold down left shift key as soon as the laptop splash screen finishes.)
  2. . Open the Recovery Console.
  3. . Run fsck. This gets the system into Read/Write mode, allowing you to make modifications. Wait until prompted, then press Enter. The Recovery Console menu will come back.
  4. . Run root. This opens a terminal.
  5. . Blacklist the B43 firmware:
  6. Type cd /etc/modprobe.d, and press Enter
  7. Type echo “blacklist b43” > blacklist-b43.conf, and press Enter.
  8. . Type reboot and press Enter. The system will shut down.
  9. . Ensure the wifi card is installed and connected (the driver won't install properly unless it can “see” the card).
  10. . Boot. Once Ubuntu has booted:
  11. . Open a terminal (Ctrl+Alt+T) and install the Broadcom firmware:

Type: sudo apt-get install b43-fwcutter firmware-b43-installer, and press Enter.

  1. . Then remove the B43 blacklist:
  2. Type cd /etc/modprobe.d and press Enter.
  3. Type sudo rm blacklist-b43.conf and press Enter. Close the terminal (Alt+F4).
  4. . Wifi should work. If it does not work immediately, reboot.
  5. In any case, reboot to test that it boots properly and does not stall in the middle of the boot.

MacBook White

Intel CPU. Ubuntu 12.04 LTS operating system.

The Glitch: the onboard microphone works fine, until you plug in an external Mic. The external Mic gives no signal and simultaneously disables the onboard Mic, requiring a restart to re-enable it.

Tests with a Mac OS on an external HDD supplied by a volunteer show that this is a software problem with Ubuntu, not a hardware problem. Extensive investigation has not turned up any software fix available at this time. Nor has Ubuntu 13.04 fixed the issue.

Proposal: Test everything we can in Ubuntu 12.04, and confirm that the microphones are working properly using a Mac OS on external HDD. Sell the unit with Ubuntu 12.04, along with a note on the Build Sheet regarding the microphone glitch, making clear that the hardware is functional but is affected by Ubuntu.

Precedents for using non-free software for testing and subsequent sale:

Broadcom Wifi cards

Nvidia video drivers

Some ATI video drivers

Ricoh webcam (principally on Sony Vaio laptops)

Apple iSight webcams

Rationale: the purpose of all our QC testing is to determine whether or not the hardware is functional. In all the cases listed above, we have no choice but to accommodate the software requirements of the component: we cannot swap out video chips or webcams, or in the case of Broadcom Wifi cards we run into brands (HP and Compaq) that will not accept any other card. If our objective is to (1) fully test the hardware, and (2) sell a fully functional machine, we have no choice but to use this non-free software.

Dell Vostro Wifi does not work

Issue: Dell Vostro wifi does not work – the “dell-laptop” kernel module is blocking it and giving the message that wifi is disabled by the hardware switch. This is the fix:

Originally Posted by chili555 With due respect to my colleagues, I think it's due to a poor implemetation of the module dell-laptop. Please do: Code: lsmod | grep dell If dell-laptop is loaded, remove it: Code: sudo rmmod -f dell-laptop sudo rfkill unblock all Is your wireless working now? If so, we'll need to blacklist dell-laptop.

The test for us will be whether this fix survives the next update, or if the problem comes back. In which case we will need to figure out how to blacklist dell-laptop.

UPDATE:

The fix did not survive the first software update. So we must do this:


  1. sudo su
  2. echo "blacklist dell-laptop" >> /etc/modprobe.d/blacklist.conf
  3. exit

Before you press Enter, proofread carefully. The double arrows append the line to any other lines currently in the file.

dell-laptop is now blacklisted and will not reload on boot, unless, of course, you edit /etc/modprobe.d/blacklist.conf to remove this line: “blacklist dell-laptop”.


Apple iSight Webcam driver fix for MacBook in Ubuntu 12.04

See http://turanct.wordpress.com/2010/06/11/use-your-macs-isight-on-ubuntu/

Text of this page follows:

Use your Mac’s iSight on Ubuntu June 11, 2010 There are two possible scenarios.

  1. . You are running Ubuntu natively (or via Boot Camp) on your Mac, and you can’t get the iSight to work with Ubuntu.
  2. . You are running Ubuntu in a virtual machine using VMWare, Parallells, or VirtualBox, and you can’t get the iSight to work with Ubuntu.

0. foolproof: if you’re trying to use your iSight in a virtual machine, make sure your vm software links the camera to the virtual machine!

1. get the AppleUSBVideoSupport file. you can find that file on an existing Mac OSX 10.4 or 10.5 installation at this location:

/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport or you can download it from here. (unzip this first)

FreeGeek Note: we have the file on USB Stick.

2 Put the AppleUSBVideoSupport file on your Ubuntu Desktop.

3 Open a terminal window on Ubuntu, and update your repositories:

sudo apt-get update

then install the iSight Firmware Tools like this:

sudo apt-get install isight-firmware-tools

4. The installer wisll ask you for the AppleUSBVideoSupport file. give it the right path to that file: /home/oem/Desktop/AppleUSBVideoSupport FreeGeek Note: This is tricky. You have to carefully delete the existing path, which is set up to assume you have a MAC O/S on the machine, (which you don't), and replace it with the path to the Ubuntu desktop. IF you fumble this, the installer will proceed anyway, then fail. You must remove the installer and try again. To remove it, enter this: sudo apt-get purge isight-firmware-tools, then repeat from Step 3.

5. Reboot or log out and log back in. You can now use your iSight with Ubuntu!

Acer Aspire 5920 Headphones don't work

Two pieces of advice:

First, from here: http://askubuntu.com/questions/176134/headphones-dont-work-on-an-acer-aspire-5920g

I had the same problem on my Acer 5930g. Even though I plugged in the earphones I hear the sound both in the built in speakers and the headphones. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the commands below. gksudo gedit /etc/modprobe.d/alsa-base.conf and add in this line at the end options snd-hda-intel enable=1 index=0 model=auto then save and reboot.

If that doesn't work, try this to get extra settings in Alsamixer:

http://askubuntu.com/questions/135804/want-sound-only-to-headphones-when-it-plugged-in-and-in-speakers-else

As ALC1200 and ALC888 seem to be very similar (see this German Wiki Entry) you can try my solution for the Intel HDA ALC1200 on my Acer Aspire 5920 G laptop. After upgrading to Ubuntu 12.04 Precise Pangolin from 11.10 my speakers continued to output the sound when plugging in headphones. In 11.10 the speakers were muted automatically when a headphone was plugged in. I fixed it by adding a line to /etc/modprobe.d/alsa-base.conf : options snd-hda-intel model=auto probe_mask=1 Now I've got a lot more options/controls when running alsamixer. One is "Auto-Mute Mode". Set this to "Enabled" if it does not work out of the box

DVD Will not work with dvdcss installed

Setting DVD Region Codes

Region codes are a form of vendor lock-in. For example, you cannot play a DVD published in Japan (Region 2) on a DVD player in the United States (Region 1) without changing the region code of the DVD player (unless you own a region-free DVD player). You can view or modify the region code of your DVD drive with the regionset tool.


The author of regionset writes: "On delivery, most DVD drives have no region code set. The drive firmware allows you to change the region code, but on nearly all drives you are limited to five (5) changes. After the fifth change, the DVD drive will stay fixed on that code -- on some drives you can upgrade the drive firmware and have then additional five changes, on other drives you won't be able to change the region code any more."

Most players (e.g. MPlayer/VLC) with most DVD drives are able to ignore the value of the region setting. However, it must be set to something; if it hasn't been initialized, even non-region-restricted DVDs won't play. Also, if it is necessary to crack the CSS key, it can sometimes take up to a few minutes to do so. To change the region code of your DVD player, insert a DVD from your region in the DVD player, and do the following:

Install the regionset package from the Universe repositories. To launch regionset, issue the command

sudo regionset
