Bug Description

Binary package hint: linux-source-2.6.27

The latest release of stk11 1.4.0 compiles under 2.6.27 giving support for a series of webcams that worked in hardy but because of this regression do not work in Intrepid.


im using ubuntu intrepid alpha5 with the original-ubuntu-kernel 2.6.27-rc6 on a asus a6t.

root@PrinzIP:/home/rafael/treiber_N_progs/stk11xx-1.3.1# lsusb |grep Syntek

standartly the stkwebcam is loaded, but dont work

I think it should, as with Intrepid release candidate the net result is no video device being detected. Those cameras are often being built into laptops which makes it essential to suppport them out of the box.

Jason Allen (jallen) wrote :

Agreed with Lex, especially as in most cases it worked out of the box in Hardy. It looks bad to have worked 100% in hardy and then 0% in Intrepid, and makes Itrepid seem a backward step, not a forward one.

With this module, camorama has video from the webcam. Ekiga also works
with the stk11xx module. So this is an improvement over the stkwebcam
module :)

But not all is good :( Cheece is not working again (No camera found)
and Skype detects the webcam, but when testing the webcam
functionality from the app settings, I only get a black screen.

I would be very interested if anyone else had better luck..

Thanks Jim, much appreciated.

I can confirm the amd64 kernel worked fine for me, with camorama working instantly. All other things/hardware worked as per 2.6.27-9-generic.

I use/run nvidia (177.82) restricted/proprietary hardware drivers and these failed on the dkms when installing the kernel deb package, and thus the nvidia drivers did not load when I booted with your 2.6.27-11-generic. I expect this is more a problem with nvidia drivers than the kernel and something outside your control?

Jos (namjos) wrote :

Hi Jim and thanks for your work

I confirm that the i386 version is working for me, tested with skype.
There's only a regression from hardy with cheese, that is no more working with this webcam, but it is as in the sourceforge repository.

I attach an lsmod output from this kernel


Jim, It sounds like we have a confirm in both 64bit and i386. I'm very eager to see this comming in proposed. Thank you so much for your work. When can we expect it?

Webcam is not detected and loading stk11 driver manually does not help. On a side note, I am resticted to low resolution graphics with my nVidia graphics card when using your kernel. Please make sure that proprietary nvidia driver is included with the kernel you propose before it gets to intrepid-proposed.

There have been a number of patches including new device support in the 2.6.28

Your feedback will help us decide which backporting option is better.

Does anyone know if this error is going to be fixed in the next Ubuntu release (Jaunty)?

I tried the current state of Jaunty and this issue is still there. The webcam doesn't work out of the box. However using the latest driver 1.4 stk11xx driver I managed to get it working. However Skype didn't quite worked with it... but this is different issue.

So Jim I think the answer is that the new 1.4 driver seems to work with 2.6.28 (the one in Jaunty).

stkwebcam does not work on 2.6.8-11 kernel and is not being autoloaded making it possible to include skt11xx driver as temporary fix. Version 2.0.0 of stk11xx driver failed to compile on 64-bit Jaunty beta for some reason, complaining about stk11xx-v4l.c code. Same thing with svn. See

Does anyone communicate with Linux kernel upstream about stkwebcam driver not supporting syntek cameras? What is the plan for 9.10 final release?

:( So I was fighting with the 1.4 version of the driver on the 2.6.28 kernel that is 9.04, but it is a NIGHTMARE. I haven't seen the linux kernel dies and burn so often ever. ;( Any attempt to start any program connected somehow with this device causes deep kernel crash and my scroll and caps lock lights start blinking. The only ways out of those crashesh was hard restart. I just looked on the web site of the driver

And there is version 2.0 of the driver but is only for the 2.6.29 kernel or later ;(
Can someone smarter help us. It looks to me like there is no good version of the driver for the 2.6.28 kernel ;(

Very sad.

Can I help in any way.

Skype, cheese, ekiga do not detect it.

Ubuntu 8.04: Work out of the box
Ubuntu 8.10: Need to compile and install manually a driver

Can it be a regression of the stkwebcam module on ubuntu 9.04?

Lex Ross (lross) wrote :

Hi Joe,

I think your webcam is only supported by stk11xx driver. Mine is ID 174f:6a31 Syntek Web Cam - Asus A8J, F3S, F5R, VX2S, V1S and it used to work with stk11xx until Ubuntu 8.10 came out. The best thing would be to implement this webcam support into stkwebcam kernel module. I wrote to Jaime about this, and he is willing to co-operate. Jaime is sktwebcam maintainer. Here is what he says.

Both the camera controller (the chip made by Syntek) and the image sensor are different than the one supported
by stkwebcam.

But, as now most applications use libv4l, it _could_ be done if it works now with stk11xx. After reading the bug report, I see several unrelated problems, so I'm confused . The original report seems to be a problem with stkwebcam, as that camera should work out of the box (it's the same as mine). The cameras unsupported by stkwebcam (as yours) should keep working the same as before, with stk11xx.

If somebody is interested in adding support to stkwebcam, I'd help, but it could become very frustrating, so be warned!

The proccess would be:
1. test stk11xx and confirm that it works
2. try to remove cruft from stk11xx until it stops working. I could send patches
3. port the code to stkwebcam and test again. I'd send patches as well
4. if all works, it'll get into Linus' kernel eventually (after 2.6.30 for sure)

And the driver will only support RAW colorspace unless somebody figures out how to program the image sensor, so the application you want to use probably needs to use libv4l (if you're interested in skype, I don't know if it would work, maybe).

That's all, if you're still interested start with step 1 and tell me how it goes.


So it's not all that easy but if we could have someone from Ubuntu kernel team on our side to facilitate the process, then support for Syntek webcams in question can be built into stkwebcam module. Otherwise I would kindly ask Ubuntu kernel team to include stk11xx driver with 9.04 final release. I am willing to help as much as I can but unfortunately do not know much about kernel development. Time to call for collective wisdom, what do you think?

Jos (namjos) wrote :

Hi Lex

The problem for my webcam is that stk11xx driver works with ubuntu 8.10 (2.6.27 kernel) but not with ubuntu 9.04 (2.6.28 kernel)

As I said, on ubuntu 9.04, stk11xx driver module compilation is OK (version 1.4.0), loads OK after loading stkwebcam, but is not usable on any program.

stk11xx needs stkwebcam module, as he need some functions of it, so we can't test stk11xx without stkwebcam. I've not currently the needed exports from stkwebcam that stk11xx needs, but I can retrieve it if you want (just load stk11xx without loading stkwebcam, and copy /var/log/message stuff)

So include stk11xx on ubuntu 9.04 will not help me to have a succesfull webcam working.

A good test, if it is possible to do, would be to compile 2.6.27 stkwebcam module source on a 2.6.28 kernel, and try to see if my webcam is working with stk11xx on top of this stkwebcam module. It may be a regression on stkwebcam module, I don't actually now.

So for your step 1, it was what i've already tested, and stk11xx not currently working with ubuntu 9.04. I was maybe not enough clear in my previous message.


I can confirm Jos story. I just want to add that I can actually get some picture using v4l2 but all the other applications that use v4l1 crash when they try to touch the webcam (My webcam: ID 174f:6a51 Syntek 2.0MPixel Web Cam - Asus Z96J, Z96S, S96S)

It is actually very scary because the kernel itself crashes very often when this program attempt to use the webcam. I'm very interested to see if the 2.0 driver works with 2.6.29 (it is supposed to). Unfortunately I don't know how to tell 9.04 to use 2.6.29 (if it is even in some repository...? is there a package somewhere?) Can someone guide me how to do this or someone can just test the webcam with 2.6.29 and 2.0 of stk11xx.

Hi there,

I've made some tests with ubuntu 9.04, and the results are really stranges.
I've build some custom kernels to try to isolate the problem.

Ubuntu 9.04, kernel 2.6.28 with stk-webcam.c from 2.6.27 kernel: Not OK
Ubuntu 9.04, kernel 2.6.28 with all driver/media and include/media directory from 2.6.27: Not OK
Ubuntu 9.04, kernel 2.6.27: Not OK
Ubuntu 9.04, kernel 2.6.27-11-generic from ubuntu 8.10: Not OK

I really don't understand what is going on now, it seems that this is not the 2.6.28 kernel that is in fault, so I don't know where it could be other than kernel.

Any ideas to test something?

Ok i've finally found what's going on :)
It's a permission issue, users on ubuntu 9.04 was not added to video
group at creation, so they do not have right to use it.

To solve it:
sudo addgroup $USER video

Then disconnect / reconnect your session, it will then work on ubuntu 9.04.

Is a bug already opened for this stuff of video group missing? Maybe we
should open one otherwise

Thanks all for the comments and sorry for for being so unresponsive. There seems to be always another thing taking precedence over this. Essentially the better way to go forward would be to get the in-kernel driver working. I saw comments about the driver in 2.6.29 being better in that. If that is the case it probably is worth looking at whether this can be backported to Jaunty (for Intrepid there is no chance for that kind of change). We not got mainline kernels at, which can be installed in parallel to the current kernel. If a recent kernel can be verified to be working, then it would be simpler to find the necessary changes.

Hi all,

I found a post wich actually worked! :-)

Kudos to noobi_agocs for making this work for me!
I had also problems whit my webcam. I googled around the web every evening after work to solve the problem. FINALLY it works for me...

I have an ASUS F5VL series laptop, and i'm using Ubuntu 9.04

So, maybe the most important thing is, that you need to download the stk11xx Syntek driver, BUT the 1.4.0 release! This is very important! I had no chance to install the 2.0.0 release...

Here you can download it:

Then, I followed this HOWTO:

This is a french HOWTO (i dont speak french), but it's excellent. I followed it step by step, EXCEPT that I didn't donwloaded the latest syntek driver using the svn command.

Later I found an english HOWTO:

After this i installed video4linux using the command:
$ sudo apt-get install v4l-conf

The last step was to add my user nick to a group that is allowed to use the webcam. The command is:
$ sudo adduser USERNICK video


After this i've tried the webcam whit: Camorama, aMSN and Skype. All of them recognized whitout any problem the webcam.

I hope this helps you a little...
Have a nice day! Cheers!


After this, as usual, my cam was upside down. Just type this on console:

$ echo 1 >/sys/class/video4linux/video0/vflip

to make it permanent after reboot paste the above line on /etc/rc.local


The above did not work fully for me. Skype does recognize the webcam now. But the image is just black. ;( Will this maybe work out of the box on 9.10?

I had this problem with the webcam in my Thinkpad, and managed to find the solution here:

Hi Amol,

Thanks for the help but this did not work for me. In skype when i start my video to someone else it is just a black picture. There are no errors or anything. The green light on the webcam lights up, but the picture is just black :(.

So sad. I have to keep two versions of Ubuntu 9.04 that I use mainly and if someone wants to talk in Skype with me I reboot into 8.04. I've been using Ubuntu since 5.04, I got this machine around 6.10. Up to 7.10 the webcam wasn't working by default I had to install drivers to make it work... In 7.10 and 8.04 the camera works out of the box I was so so happy and you actually see improvement. Than regression 8.10, 9.04... ;(( and no fix on the horizon. Can't even make it work compiling drivers and stuff.

Anyway thanks for the help Amol.

It works on preview in Skype, but not yet tried calling.
Hope this helps.
It seems that there is a syntax problem with the stk11xx-v4lc.c file that is shipped with the source files, but I can't work out what it is as I am rubbish at that sort of thing.

Thanks Judderman.

I actually grabbed revision 99 from the svn. This is the future version 2.2 of the driver and I had no problems compiling it. It now works. I will try to soon test if maybe the webcam works out of the box on 9.10. But I think that now that the driver compiles and looks better it should come with the kernel by default ...

There still work for this bug, but it looks closer.

Now in lucid it is finally detected under lsusb, but not seen by skype or cheese. This means I still have to use windows for times when I need the webcam (which are very seldom these days, thankfully).

The same for me (Asus F3Sa, ID 174f:6a33 Syntek Web Cam - Asus F3SA, F9J, F9S, Ubuntu Lucid). The camera is not detected by Skype/Ekiga, while working perfectly with Hardy.

Hope it helps

Hi dpanario,

I execute your script and successfully install the driver, I can find stk11xx.ko in /lib/modules/2.6.32-24-generic/kernel/drivers/usb/media, but I got error message (screenshot attached) when I open Camorama, any comment about this? thanks.

The driver does not compile on x64 Ubuntu 10.10 release with 2.6.35-22 kernel. See error log below.

Two years with this bug and more to come. With regressions like this one I wonder how anything can be possibly certicied to work with Ubuntu. Well, until next release.

In relation to comment #56, I had the same problem under Kubuntu 10.05. To make it work I removed that offending. "compat_ioctl" field (it's just at the end of the file).
It seems that the problem is that CONFIG_COMPAT is (incorrectly?) defined.

Obviously I meant Kubuntu 10.04, sorry for the typo.

Neither Intrepid nor Jaunty are supported any longer. If this issue still exists in a supported series, please file a new bug.

Changed in linux (Ubuntu):

Very nice indeed. The problem still exists in 10.10 (Maverick) with kernel versions up to 2.6.35-28
More than two years with no video calls! Is there a problem to include stk11 driver with the new kernel release?
I was able to compile and install the driver at some point but then having to recompile it after each kernel update is a royal pain in the arse. Is there a chance that upstream developers aren't even aware of this bug report?
