Ubuntu :: Removing Built In ALSA In Kernel?
Aug 9, 2010
I am trying to update ALSA drivers which are built-in in the kernel.
I downloaded the latest ALSA drivers 1.0.23 and tried to compile but came with this error (that is the last part of it)
Code:
*** NO PREDEFINED KERNEL COMPILER IS DETECTED
*** Assuming the same compiler is used with the current system compiler.
[Code]....
Is there a way to remove the ALSA driver from the kernel so I can configure and compile the new ALSA driver ?

It was recommended to me that I remove pulseaudio and re-install alsa. All the howtos on reinstalling alsa had instructions for re-installing alsa from the source. Is it possible to re-install alsa from the repos? If so what are the necessary packages that I need to install, for a complete re-install of alsa?

I m trying to install Alsa for playing wav files I typed this: aptitude install alsa-base It started removing a lot of software from debian. Is that expected with that command? Do I need to install another "base" to bring things back?

I want to remove pulse and install alsa instead but I can't seem to be able to do it. I tried to search for all packages with "pulse" in their names and purging them but it didn't work because aptitude wanted to remove all of the packages that used pulse with along with pulse.

Months ago, I tried to get my notebook's internal modem working, by installing alsa-driver-linuxant-1.0.23.1-1.noarch.rpm and hsfmodem-7.80.02.06x86_64full-1.x86_64.rpm, both from Linuxant. This did not work, but my system was stable and the sound device (Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)) worked fine.In the last few days, I upgraded to the latest kernel 2.6.35.12-88.fc14.x86_64. Boot failed due to an inability to build the alsa-driver-linuxant against the kernel source (I have the kernel source in /usr/src/kernels/2.6.35.12-88.fc14.x86_64/). The message in boot.log was:
Code:
ERROR: Build failed. Please review the build log at /var/run/alsa-driver.1367.log.
/var/run/alsa-driver.1367.log contains the error:

Is there a DEB of the 2.6.32 Kernel with the BFS Scheduler built in? I'd like to give it a run, but I'm not so sure about compiling it on my own.

I got last night debian 5 stable, but it has an older version of kernel, I think 2.6.26, which doesn't have my network card drivers. I tried to install myself the kernel, but I a newbie in linux, so something failed and I give up until next time. Is this version: [URL] a safer one for a desktop computer, daily usage? How to I know it has the latest kernel?

I have a custom built 2.6.37 kernel where I have most of my devices compiled into the kernel. The only modules are related to nouveau (in case I want to go back to proprietary nvidia) and sound drivers. Everything seems to be running fine. However, in /proc/acpi, I'm missing a number of entries, such as thermal_zone/, dsdt, etc. I do have ac_adapter/, battery/, button/, event, processor/ and wakeup. I've gone through what I think is a very detailed review of my kernel config, and I can't find where I've missed something ACPI related. Here is my kernel config with the ACPI section.
Code:
# Power management and ACPI options
CONFIG_ARCH_HIBERNATION_HEADER=y
CONFIG_PM=y
# CONFIG_PM_DEBUG is not set
CONFIG_PM_SLEEP_SMP=y
CONFIG_PM_SLEEP=y
CONFIG_SUSPEND_NVS=y
CONFIG_SUSPEND=y
CONFIG_SUSPEND_FREEZER=y
CONFIG_HIBERNATION=y .....

I read over the X11 acceleration in this forum but I'm not having issues with acceleration - running slackware 13 with built in ATI AGP stuff in kernel. Glxgears is putting out what I would expect for a 9600 pro (2500 FPS in the little window). I haven't needed you guys for a very long time but I just formatted Ubuntu (was getting on my nerves) and installed slack 12 on my hp netbook and 13 on my old desktop without a hitch - except this
I NEED BIG DESKTOP! I've searched, I've read, I've wondered! What's the normal setup in xorg.conf for bigdesktop WITHOUT the ATI driver (I ran the driver after building a custom kernel and the installer crashed with "Error: ./default_policy.sh does not support version" - I think I should of renamed my kernel path and setup differently or something)? Is BigDesktop ONLY supported with the driver? I know now that the driver wont work for my system - How do I enable bigdesktop with the open source driver I built in?

Is there a way to programmatically determine whether a particular driver support is built-in rather than a loadable module? I'd be grateful if somebody would share how. I have written a shell script using the RTC (real time clock). I can check whether the rtc-cmos kernel module exists and load the module accordingly as needed, but I don't know how to determine when the driver is built-in. Of course, if the driver is built-in then the module does not exist.
I seem to recall there is a method to query the kernel config file (/proc/config.gz), through which I probably could grep for the CONFIG_RTC_DRV_CMOS parameter. I also can check whether /proc/driver/rtc exists. If that file exists then either the driver is built-in or the module was loaded.I realize the rtc-cmos driver is built-in with the standard Debian kernel build, but I still would like a way to query where the driver is supported.Is there a straightforward or direct method to query the kernel whether a particular driver is built-in?

Squeeze-beta was my first foray into Debian, and I love it. I changed my setup to a rolling setup with testing (Wheezy), and have done that for several months. Lately, I got a new kernel, but it reboots to a terminal rather than GUI (I'm a simple laptop user). I think it's because of the NVIDIA drivers, and here is what I've tried (meanwhile, I'm using the previous kernel):
# apt-get install module-assistant nvidia-kernel-common
# m-a auto-install nvidia-kernel${VERSION}-source
A blue screen appears that says:
module-assistant error message Bad luck, the kernel headers for the target kernel version could not be found and you did not specify other valid kernel headers to use.
You can try:
module-assistant prepare
or
apt-get install linux-headers-2.6.38-2-amd64
I have done both, rebooted, and I still get the blue screen. I also see this message:
nvidia-kernel-source was not built successfully, see:
/var/cache/modass/nvidia-kernel-source*buildlog*
...and I have copy/pasted the file below (which omits lines 101-200 because this message is too long then):
/usr/bin/make -f debian/rules clean
make[1]: Entering directory `/usr/src/modules/nvidia-kernel'

I've posted here before (viewtopic.php?f=5&t=66322) about problems arising from my attempts to get an nVidia driver to work with my custom kernel. Now those problems are all fixed, and I'm back to where I was: the built kernel boots fine, but the nVidia driver fails.
The custom kernel is as near to the stock one as I can make it, I'm just trying to find a working build process at present, before trying to build a later-version kernel.
I used sgfxi with "-! 40" to build the nVidia driver for my custom kernel; it reported that everything was fine.
With stock kernel - 2.6.32-5-amd64 ...

after upgrading to make 3.82, I can not compile the newest kernel: 2.6.35-rc6-git5，it failed with:
GEN /home/aaa/tools/kernel/output/35/Makefile
CHK include/linux/version.h
CHK include/generated/utsrelease.h
[code].....
Maybe 3.82 has some backward-incompatibility that breaks kernel compilation.

I just updated the kernel to fix nvidia video problem. But now I have problem of no sound. I think it may be unrelated to the upgrade of kernel because most or all of the symptoms were already present, or the upgrade may have complicated things even more. Another recent symptom in conjunction with this problem is that "restart" and "shutdown" from panel dropdown do not work -- they just log out. May or may not be related at all.
Here is link to output of alsa-info.sh: [URL].
I saw this thread about upgrading alsa, but it seems to indicate that later than 2.6.32 kernel not supported (????): [URL]
Here is my /etc/modprobe.d/alsa-base.conf. The last line, "options snd-hda-intel model=basic" was from suggestions I found in other threads.
Code:
# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2
install sound-slot-3 /sbin/modprobe snd-card-3
install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7

How do you go about removing old kernel from other distros from the grub menu. For example I have lucid and ubuntu studio installed. Lucid controls the grub2. So how would I remove the old kernel out of the ubuntu studio?

I followed this doc for the "debian method" for building the kernel: [URL]. I installed the source in /var/tmp/src/linux-2.6-2.6.32 , configured it, and tried make-kpkg modules-image. The error I get is:
checking for current directory... /usr/src/modules/alsa-driver
checking cross compile...
checking for directory with ALSA kernel sources... ../alsa-kmirror
checking for directory with kernel top-level makefile... /var/tmp/src/linux-2.6-2.6.32
checking for directory with kernel headers... failed
make[2]: *** [configure-stamp] Error 1
make[2]: Leaving directory `/usr/src/modules/alsa-driver'
make[1]: *** [kdist_image] Error 2
make[1]: Leaving directory `/usr/src/modules/alsa-driver'
Module /usr/src/modules/alsa-driver failed.
I tried some hacks such as setting KBUILD_SRC or ln -s linux-headers-2.6.32-5-amd64/ /usr/src/linux - but these fail too.

I just got the upgrade for the Linux Kernel version 2.6.40-4 on my Fedora 15 x86-64 box today, and the installation completed with no problems. However when I rebooted after doing the upgrade, I noticed that I had no sound. I use an ATI Radeon HD 4350 video card, and the opensource ATI driver, and use the HDMI audio from it for sound, since my monitor has a sound output jack on it. I've booted into the previous kernel (2.6.38.8-35), and sound works fine. I've tried with the new kernel in both KDE (my default desktop environment) and XFCE to get sound, and it does not work in either one. I've tried installing the VLC Phonon Backend instead of the GStreamer Backend, reinstalling Pulseaudio, reinstalling Alsa, modprobing the necessary modules needed for the card, checking all configurations with the available Pulseaudio tools (paprefs, pavumeter, pavucontrol), checked the volumes using alsamixer, and reinstalling the ALSA Pulseaudio plugin. After trying all of these, I can still get no sound out of any application, and I also noticed that Flash video plays at 2-3 times it's normal speed after the upgrade. Again, these problems do not occur on my previous kernel. Did I maybe overlook something, or can anyone else think of something I could try?

Here's how to always have only the latest kernel version in your grub:
Code:
sudo gedit /etc/grub.d/10_linux
Find these lines:
Code:
list=`for i in /boot/vmlinu[xz]-* /vmlinu[xz]-* ; do
if grub_file_is_not_garbage "$i" ; then echo -n "$i " ; fi
done`
And change it with this:
Code:
for ver in /boot/vmlinu[xz]-* ; do
list="$ver"
done
Notice two differences.
1. There's no ` before "for" and after "done" keywords.
2. There's no list= before "for"
If you want to change the name of entry, scroll down to the end of the file and find last two occurrences of:
Code:
linux_entry
${OS} stands for Ubuntu and ${version} stands for your kernel version. I changed this into:
Code:
linux_entry "${OS} 9.10 Karmic Koala"
You can use your own imagination. If you want to have specific name for your Windows entry, in /boot/grub/grub.cfg copy everything between:
Code:
### BEGIN /etc/grub.d/30_os-prober ###
and
Code:
### END /etc/grub.d/30_os-prober ###
paste it in
/etc/grub.d/40_custom
Change the text between double quotes right after menu entry. (For example, my 40_custom looks like this now:
Code:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the menu entries you want to add after this comment. Be careful not to change the 'exec tail' line above.
menuentry "Windows 7" {
insmod ntfs
set root=(hd0,1)
search --no-floppy --fs-uuid --set bcdc24dddc249424
chainloader +1
}
)
and make 30_os-prober not executable:
Code:
sudo chmod -x 30_os-prober
If you want to remove recovery mode entry, just uncomment this line in /etc/default/grub:
Code:
#GRUB_DISABLE_LINUX_RECOVERY="true"
PS Don't forget to run
Code:
sudo update-grub
After you finish editing everything! And check in /boot/grub/grub.cfg if everything is ok!

I have winxp and ubuntu 10.04 dualboot. They were working ok. Today I removed old *21 kernel image and headers so grub updated the confs. That's all I did that could cause the win no longer boot. It starts booting, the screen goes black and the PC reboots. I tried safe mode, it started to load some dlls as it usually shows in safe mode but then still reboot.
Code:
$ sudo fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I have looked for existing threads on this issue, but found no matches, so I am starting a new one.I first installed Ubuntu 9.04 on my laptop from a bought CD last year. When I later installed the kernel updtates with the Update Manager, I noticed the the list of versions growing when I booted up. Then something horrible happened. After installing maybe the third or fourth kernel update, I couldn't boot into Ubuntu, it failed every time. After that I left Ubuntu broken on my laptop for a while.I have now reinstalled from the CD again However, I am now very wary when it comes to installing even the important security updates, never mind the recommended ones! I prefer to keep it simple, because I don't want to do any more reinstalls for a while. So far I have just one kernel headers update on the boot list, and I am trying to figure out how to remove the previous one. I do not see the point in having a growing list of them again.

I have Ubuntu 10.10 installed on my laptop.Its a dual boot with XP, have been using ubuntu/xp for a while now..Till now i always used to remove older kernel images after ubuntu update, then update grub and do "sudo apt-get autoclean" never had any problem at all.i skipped the second step, i removed the old kernel image and did "Autoclean" on apt-get but forgot to update grub.
Now after i have reboot, when grub loads i can see only 2 "Memtest" lines in grub list and 1 "windows xp" line.the "Linux kernel generic" line is missing. I can boot in xp (have done just that to post this) but since there is no line in grub list to boot into Ubuntu, cant boot in Ubuntu.Is there any option, something i can do at "Grub" to boot into Ubuntu?

I installed the kernel source RPM to add a patch to a driver kernel module that didn't support my NIC. Now that the patch is part of the official source tree I no longer need the kernel source and I want to delete it. Can I just do rm -rf rpmbuild or do I need to run the reverse of the rpm commands described in Section 1 of [URL].

How do I remove old kernels from the Fedora grub menu? I have three currently and I want to keep only one old version to fall back if I have any problems with the current one. When I was using Ubuntu, I had Ubuntu Tweak which had an option to clean up old kernels from the grub menu .. is there something similar for Fedora?
I'm using Fedora 15 32-bit with Gnome 3.

In trying to get something else working, I installed a newer version of the kernel from backports (I'm on 2.6.26 lenny and the backport kernel is 2.6.32). That failed, so I want to remove the backport kernel completely.
I tried:
Code:
and got:
Code:
Accept this solution? [Y/n/q/?]
I don't really understand how these metapackages work and I don't want to accidentally remove my currently-working kernel.
What's the correct way to remove all packages related to the backports kernel and leave the existing lenny ones alone?

I am an old Debian user, ho just reinstalled it again to see how it evolved since my las version (3.2). I am sharing it with Arch Linux, And decided to let bot of them. I am using GDM compiled and configured in Arch, and removed GDM2 from Debian (i just like the easy menu.list from the old GDM). The problem is that when i update the kernel, it didn't fing GDM and drops an error message. I tried removing the distro-preconfigured Kernels, as i compiled my own 3.0.0-rc2 Kerenel, but i cant delete the previous ones. Now everytime i do an install or uptgrade, apt-get drops wastes some time, and drops an error message:
[code]...
What can i do? i googled some similar errors, but where just messed up mirror.lists, or similar, i know it isnt the cause of fail.

I had the 180.xxx nvidia drivers on my FC10 setup.I installed the 185.xxx and am running into issues. It gives me the fatal server error: no screens found message. Before that it says that the nvidia kernel module is 180.xxx and the driver component has 185.xxx. I can't seem to figure out how to uninstall the previous module to make this work. I removed the yum kmod nvidia. I'm running this using sh nvidia.185xxx.xxxx.run . The weird thing is that it sometimes would work but then I would restart and it would break again.
Thanks in advance,

As it written here [URL]. Fedora 13 does not include the kernel-source package provided by older versions, since only the kernel-devel package is required now to build external modules. Linux kernel, does not belong to fedora. Fedora is derivative work isn't it? Or you rewrite all kernel in fedora 13, and fedora is not linux any more? According to GPL, derivative works must be licensed as GPL. And so you must provide ALL sources for free. Including kernel sources. So, where can I get kernel sources for fedora 13? Or I'm wrong, and you shouldn't provide them if you wont?
