Automatically Recompile AUR Module on Kernel Update?

I'm using acpi_call-git from the AUR to turn off my NVidia graphics card on my Optimus laptop.
It works great, but it breaks every time there is a kernel update.
I have to recompile and reinstall the package, and then reboot again.
Is there a more convenient way to get this done? I've tried recompiling before rebooting on a kernel update, but the compilation inevitably fails.
Any advice would be appreciated.

yes there is a dkms version in the AUR. http://aur.archlinux.org/packages.php?ID=54641
It will automatically recompile the module when a new kernel is installed. "dkms_autoinstaller" will need to be added to the DAEMONS array in /etc/rc.conf

Automatically build kernel module after kernel update

Hello. Everytime kernel is updated, my wifi drivers don't work. I need to use this to get my adapter working: https://aur.archlinux.org/packages/8192cu-dkms/ .
After kernel update, I have to manually reinstall the package, so the kernel module gets rebuilt. Is there any way to make it automatic?

I noticed it, but your script doesn't run at all when I type `mkinitcpio -p linux`. And wifi still works after reboot. Same for graphics driver, it has a hook at shutdown, that rebuilds its module after kernel update, it haven't run too and graphics driver works. It's like 'mkinitcpio -p linux' does nothing to the system.

Automatic recompiling of kernel module after kernel update.

Hello everyone,
i tried to search for it but without success...
my question is - is it possible to set it up somehow that aur package would recompile after kernel update?
The package I would like to rebuild is rt3090 which is module for my wifi card. It is very annoying to rebuild it manually. I know that my fglrx module does it automaticaly but how to set it?
Thank all of you for any advise.

Thank you :-) It looks ok, I will try DKMS as soon as I get some free time. If there was any problem, I would tell you.
BTW: I use catalyst mainly because of saving energy management, which is of course better for my netbook. My card is too new to be fully supported by the opensource driver.
EDIT:
I solved the situation by upgrading my system, I tried in-kernel module rt2800pci. In the previous kernels it didn't work well with my crappy ralink rt3090 wifi card, but that's been improved :-) so I do not need rebuild the package anymore even because this module isn't compatible with newest kernel.
I also learnt how to write my own hook from archwiki (https://wiki.archlinux.org/index.php/Mkinitcpio) so if the new module didn't work I would try it.
The final solution = replace module rt3090sta by rt2800pci.
Thanks! Arch has very powerful community :-)

Auto rebuilding module after kernel update?

Hi,
I'm using the package broadcom-wl on my Arch-laptop, and it has to be rebuilt everytime I update the kernel. That is no problem until you forget it once and have to go looking for that cable that the misses has thoroughly hidden from me.
Is there a place where I can f.e. specify which modules have to be rebuilt after the kernel is updated? This package is in AUR, so that might pose another problem?

Yeah, at that time, I didn't think of that...

That would be nice - I'll keep an eye on that one...

[kernel] kernel update and third party modules management

Hi all,
I turned to Archlinux with my new thinkpad X220 just for a few days, while I have used Ubuntu for 4 years. I had never controlled my system in such a degree, and feel happy about it.
However, I have a question about kernel update, for I had install some modules from AUR with yaourt( e.g. tp_smapi, acpi_call). For my poor knowledge about pacman, I don't know how to handle those modules while I upgrade my kernel. I cannot remember to re-install all of them!
I think there must be a solution that I didn't found, so I write this thread to ask for help.
Any help would be appreciate.

Mr.Elendig wrote:You can use some silly wrapper around pacman that rebuilds them when there is a kernel update. I'm sure someone has written one already.
Thank you, Mr.Elendig. Do you mean some kind of frontend such as yaourt?
Or some kind of hooks like this:
aur/mkinitcpio-vbox 2.0-3 (Out of Date) (29)
VirtualBox hook for mkinitcpio that rebuilds kernel modules on next reboot
Using the key words you provided, I searched " kernel upgrade module rebuild " and found that gentoo offically provide a tool called "module-rebuild" to reinstall external modules. Maybe it's because gentoo always compile source code? But no other results.
However, now I found what I need to do is just to build the modules listed in the /etc/rc.conf, and that is acceptable. Maybe after a few weeks of study, I can find out my way to solve this problem.
And thanks for your reply.

DKMS - module not compiled after kernel update

Hello all,
I'm using a USB Wifi Adapter which has very bad support : D-Link DWA160 B2
I have followed the instruction from this excellent guide to add the driver sources to DKMS, to get it compiled automatically after all kernel update:
http://bernaerts.dyndns.org/linux/229-u … er-to-dkms
Unfortunatly the 2 last kernel upgrade did not trigger the driver compile.
There is no DKMS logs, and everything seems to be well configured.
My DKMS conf file:

Are you using systemd? If so, you might have to reboot twice. The catalyst-dkms package (video driver for amd cards) in [community] currently has the same problems. I'd suggest for you to read the last few pages in that thread to see background information:

Yes I do use systemd. Since I'm using a quite recent installation, it was included by default.
At the next kernel upgrade I'll try this trick of reboot twice, and see if it works.

Module 'asus-nb-wmi' stopped being auto-loaded after kernel update

Well, the module 'asus-nb-wmi' which takes care of some FN keys and keyboard backlight stopped being auto-loaded after the latest kernel udpate (3.9.3), so I had to add it to /etc/modules-load.d/ to get it working. This has happened before, between kernel updates and I had to re-install arch to fix it, but now I found that manually adding the module is a nice solution, but I want it to be loaded automatically or at least know why does this happen. Kernel modules, such as this one, should be loaded automatically right?
Best regards.
Last edited by DanielRS (2013-07-04 19:54:48)

I think there is a valid question here; Same thing happened to me.
Upon a default install of arch, the module was auto-loaded without the user touching any configuration files
at some point during kernel updates, the module is no longer auto-loaded
the user then has to find out what is happening and go add the module to the appropriate config file to force load on boot.
So the larger question is; without config files being taken into consideration, how does the kernel decide what modules to load? f
I know it has something to do with the hardware that it detects, but am unaware if this is something within the RC or systemctl booting system, or if this is part of the kernel.
I'm going to dig around some more on the internet, as i'm sure the answer is out there somewhere.. but if someone that is on this forum happens to read and know the answer, it would be nice to know
thanks

[Solved] Can not build modules for VMware Player after kernel updates

I have a problem generating the modules for VMware Player after kernel updates. I am using VMware Player version 5.02 (without patches) and the softlink according to the Wiki.
When I start the installation of the modules from the GUI, the program just closes. Running vmware-modconfig in the CLI generates the following log file:

Interestingly, after deinstallation and reinstallation the VMWare Player works fine.
Any hint, what's going wrong?

Today, (Kernel 3.10.5-1, VMware Player version 5.02 with kernel patches) the modules could successful be generated from the CLI:
vmware-modconfig --console --install-all
Solved (somehow).

[Solved] Nvidia after kernel update

The nvidia wiki clearly states that: "Every time the kernel26 package is updated, it is a requirement to reinstall the nvidia package and rebooting afterwards. "
But my question is, why? I mean, if the module was to be recompiled, that would make sense. But what does just reinstalling the driver accomplish? In my system, pacman -Ql nvidia shows:
$ pacman -Ql nvidia
nvidia /etc/
nvidia /etc/modprobe.d/
nvidia /etc/modprobe.d/nouveau_blacklist.conf
nvidia /lib/
nvidia /lib/modules/
nvidia /lib/modules/2.6.35-ARCH/
nvidia /lib/modules/2.6.35-ARCH/kernel/
nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/
nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/video/
nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/video/nvidia.ko
From what I've read, I think the kernel update process copies the compiled modules into the proper folder (inside /lib) named by the kernel version. Should this not be the case with nvidia? If it is not, then is this why the reinstall is needed?
Thanks in advance (and my apologies if I've glossed over something that's patently obvious --- while I've searched for the answer before posting, I am still quite the novice at tinkering with the kernel)
EDIT: just after posting I've realized that maybe this post belongs in "Kernel and Hardware Issues" subforum. But the truth is this isn't really an "issue"... it's more a question from, well, a newbie :-)

Running the risk of asking what might be obvious to some, why?
The driver speaks to the kernel. When the kernel updates, the language used might have changed in various ways. Since nvidia is closed-source, its not always obvious whether what has changed affects it. The same applies to xorg-server, when it updates you should recompile your nvidia driver. Its SOMETIMES not needed, but when it is, would you rather be solving it from the tty?

Now I'm confused. Are you saying that the safest approach is to recompile and (re)install the nvidia module after each kernel update? And does this only apply to modules from beta & AUR, or [extra] as well? And shouldn't all this issue of recompiling modules also apply to every other module installed in the system?
Yes that's the safest approach. [extra] is taken care of by the devs, the simple way is to assume they'll bump it if needed (and you don't need to do anything).
The same thing applies to almost any kernel module (AFAIK). It applies to virtualbox's modules, for sure, as well as phc-intel (the only other 2 external modules I use). Most kernel modules are actually compiled in to the kernel26 package anyway, so its not very many. I just automatically recompile the ones I use whenever I notice a kernel/xorg update.

Broadcom-wl-dkms not reinstalled after kernel update

I use broadcom-wl-dkms for my wireless card (Broadcom BCM4352 rev 03). All works well, until the kernel is updated.
I expected dkms to rebuild the package automatically, but apparently something goes wrong in the process: after every one of the last few kernel updates, the module was correctly rebuilt on reboot, but not re-installed.

Apart from telling me that the broadcom-wl install failed, I don't see much in there.
Any clue on what's going on? Thanks!

The open source driver might work or might not. For me it was extremely unreliable and slow. Use the broadcom-wl driver or b43 like ugjk suggests.The wl driver is in aur.

[SOLVED] no timidity service + pulse, kernel update (3.16.3-1)

I had sound working before upon boot, but sound was failing after resume from suspend on HP dv7 laptop. I hadn't gotten around to figuring out how to store alsa state (what I believe to be the solution to sound failing after suspend). My install is about a week old. I ran pacman -Syu to get into the habit of doing so. Now I know why it is suggested to not do the updates when you don't have time to fix things that might need to be fixed.
alsamixer is not muted, but I only see master channel as user or root - selecting the Intel PCH sound card within alsamixer allowed me to see the other channels, but speaker-test remained silent. But I have been consistently seeing PCH Transcoder A errors on boot. Wasn't sure what they were, since everything had worked prior to kernel update. Investigating sound yields my hardware is Intel PCH, so these errors may be important, but I am also unsure how to access any log they might be recorded in.
EDIT: speaker-test and timidity work in single user console mode, but not in KDE.

Any ideas on what I should do? Also, why did my sound break, and what should I do to prevent sound from breaking in future kernel updates?

Since it appears that my issue is a KDE issue, not ALSA, I'm working through the troubleshooting on the Pulse wiki page here.

fluidsynth (needed for Rosegarden) has been told to use pulseaudio instead of alsa directly (as per https://bbs.archlinux.org/viewtopic.php?id=154002 )
What worked to get speaker-test running in Konsole: adding -D to:
ExecStart=/usr/bin/timidity -iA
to become
ExecStart=/usr/bin/timidity -iAD
in /usr/lib/systemd/system/timidity.service (as per: https://bbs.archlinux.org/viewtopic.php?id=149339&p=2 post 29)
Additionally, I was able to see a default audio device in KDE system settings...multimedia instead of just dummy device. However, even after preferring the default audio device for everything (and it tests fine), Rosegarden still has no volume. Timidity in Konsole plays audibly now too. I am now going to reboot and see what the status is.

Kernel update (3.9.5-1) causes graphics issues, X11 "no screens found"

Earlier I updated my system with pacman -Syu. Everything went smoothly. I rebooted and immediately noticed something was wrong with the console framebuffer - printing and scrolling are very, very slow and jerky, an error flashed by after fsck too quickly to read (since disappeared), and startx gave me the "no screens found" error. I do not have any custom X11 configuration.
This is an MSi laptop with the (awful) nVidia Optimus (hardware mux).
IGP is an Intel Ivybridge Mobile (GT2), don't know the exact chipset model, X logs indicate it's the i965.
DGP is an NVIDIA GK104M (GeForce GTX 675MX).
(New) Kernel: 3.9.5-1-ARCH #1 SMP PREEMPT ... x86_64
(Old) Kernel: 3.9.4-1 ...
I should mention that I use the acpi_call package to shut the DGP down, the command runs automatically at boot (but does not work! An AE_CALL error message is given, I have to run the turn_off_gpu.sh script manually after login). Nouveau is still being loaded into the kernel, regardless. I have tried removing the .conf file used by acpi_call from /etc/modules-load.d/, there was no effect. I also tried downgrading from the latest xf86-intel driver package, again, no effect - under either kernel. Additionally I tried using nomodeset and i915.modeset = 1 kernel parameters (which were necessary with a previous kernel version or Arch was unbootable, but not with 3.9.4-1). No effect. Each change was followed by a reboot, just to be sure. Systemd is loading everything normally except that it complains of no display-manager service ... because there isn't one.
It may be trying to use the DGP, for which there are no drivers installed, as I have no desire to use that card with Linux, ever; I've no idea why/how a kernel update would change this, as I mentioned I have nothing fancy going on with kernel 3.9.4-1 and the graphics setup and X11 work just fine out of the box.
Thanks in advance for you help.

No, the i915.modeset parameter was necessary with an older kernel.
I've now also tried kernel 3.9.6-1 and nvidia drivers, with AND without an xorg 10-monitor.conf file. Running kernel 3.9.6-1 seems to fix the console framebuffer issue, but the "no screens found" issue remains, xserver logs complain of not being to find intel module when using nvidia drivers (which require removal of intel drivers), and both sudo and netctl are broken - logs list pam-unix "conversation failed" error and time-out/failed dependency waiting for wplXXX - the wireless NIC - to start.
Just to see, I tried the nvidia drivers with kernel 3.9.4-1 and got the "no screens found" error.
Because I couldn't access the internet under kernel 3.9.6-1, I didn't get to test it with nouveau but I can't see how that would be any different - it has no Optimus support, anyway.
One more probably unrelated thing: all indicator LEDs (except power button) and touch-button LEDs no longer light up, under 3.9.4-1 with no changes to packages in a few days.
I'm stumped.

Driver compilation after Kernel update [SOLVED]

Do I have to compile drivers again each time the kernel gets updated? It's just a bit annoying, was wondering if that was really necessary?

Lol hadrons123, that must've been the most stinking nerd posting I've encountered in quite some time really^^ Now go out the basement for a change. I can already begin to imagine what your tone of voice must sound like when you "teach" someone irl how to ask questions..
And to be more specific: Obviously I meant if I compile a driver myself, and then the kernel gets updated, it seems I have to compile it again. Also, this is in the newbie forum for a reason.
Linux is a monolithic kernel. All needed drivers/features are supposed to be compiled into the main kernel. However, this is infeasible due to the wide variety of hardware. Therefore, some parts of of the kernel are compiled out into modules that can be loaded into the kernel at run-time. These modules need to be recompiled every time the kernel is as they are really a part of the kernel and the kernel doesn't have a stable binary API.

Lost network after kernel update

Hi
I have lost my network after kernel updating the kernel [2.6.35.7]
I downgraded to kernel 2.6.35.6

Hi,
I'm just reporting that I had this issue today too. I rebooted my computer from Win7 to Arch64 and I was left without network. Also it doesn't work in windows after rebooting back. I thought that It is something with connection so I tried to recoonect cable and also tryied to swap it in switch/adsl gateway. It started working after several switches (not on 1st!) It looks like interface is repeating on and off. So I rebooted to Arch and it stops working again...
I fixed it by reinstalling kernel26 package. But it is strange because it works yesterday, last thing what I did with kernel and modules was update of gc nvidia drivers... I don't know when I updated kernel last time
I'm using same network driver as Karol - r8169
lsmod | less
mii 3826 1 r8169
I'm using this card as well. I upgraded yesterday and I can't get wireless with WICD. Windows and normal network daemon work fine. I use kernel26. What other info can I provide? If a bug report needs to be filed, would it be WICD, kernel26 or other?
Also, I forgot, but I'm not using normal Wicd, I'm using wicd-nogtk from AUR. Krychle, are you using this also?
Edit: I think this has to do with the python update. I updated wicd-nogtk and its good now. I am online.
