Re: Mini 9 kernel update?

David,

I flashed the bios to A04, and went to update manager and have it downloaded and installed all the updates. After that I exchanged the 1gb ram with the 2gb and the system reconized it. I really don't know much about the process since I'm a Linux newbie. My wife is travelling with the mini right now, I'll check for the kernel version next week, well... if I can find where to look for it.

Re: Mini 9 kernel update?

There was a largish update bolus that was pushed out about 3-4 weeks ago, and that may have updated the kernel. But if so, then Dell's kernel update script also deleted the previous kernel version because I can't find it. Thus my confusion.

Two easy ways to check your kernel version:

1.

# uname -a

You'll probably find that you're running the 2.6.24-19 kernel

2.

# ls /boot

The /boot directory is where your kernel images are stored. You'll likely find that the only thing you have there are the 2.6.24-19 kernel and its associated files. But not any previous kernel version.

 

Anyways, I'm told that "3-4 weeks ago" (well before Dell started selling 2gb Minis) the kernel was patched up to support 2gb. But the Dell-buntu hides your updates from you so you'd never actually know that it was changed if you did an update (as I do, regularly).

 

On faith that it will work, I already ordered the 2gb stick that I need. Hopefully it shows up today.

Re: Mini 9 kernel update?

In deed my kernel version is 2.6.24-19.  But when I check my bios, the main page shows system memory 640 kb, extended memory 2038 mb.

Re: Mini 9 kernel update?

My system has faithfully and regularly been kept up to date. My 2gb stick from Crucial arrived yesterday, swapped it in, and 2gb shows up everywhere it is supposed to: in bios and in linux. XP? Don't use it. Current kernel supports it properly. No problems at all.

 

Bonus: boot time (MBR to GDM) is down to ~13sec now.

Re: Mini 9 kernel update?

I installed the BIOS update A04 and the kernel update using update manager. Now my built in webcam has a problem when I try to run Skype or Cheese. The webcam light comes on and I get a image for an instant then the image breaksup. I went back to BIOS A00 with no luck. I then installed A04 back and booted a thumb drive with Ubuntu 8.10 on it. The webcam works perfect. I can only assume the kernel update is the problem. Any suggestion?

Re: Mini 9 kernel update?

matracb:

In a terminal session, enter:

# uname -a

Tell me what the version of your kernel is. It should read:

2.6.24-19-lpia

 

1. Are you running the stock Ubuntu that came with the Dell Mini (8.04.1 lpia aka "Dell-Ubuntu"), or something else? I'm assuming you are, and that 8.10 is only running from a stick.

2. When you did the kernel update, did you update everything else needed or did you selectively update only the kernel itself? Skype and Cheese share a commonality with a webcam kernel module that may not have updated properly. So its not that the -19 kernel is the problem, but that its not loading the right module to handle the webcam. Or the HAL is corrupted. You may need to do a simple dpkg-reconfigure, but I suspect that the module didn't update normally, and that would be what happens if you selectively updated only the kernel and not the associated restricted-modules package.

3. After finding that generic x86 Ubuntu 8.10 works fine, did you then boot back to whatever is installed internally and find the webcam now works fine?

4. Prior to doing your BIOS updating, did you reset the BIOS to "default"? Have you ever changed any of the BIOS settings? Would you please humor me and go into your BIOS settings and manually set them to default, then boot back to the "Dell-Ubuntu"? Just trust me on this one please.

 

None of my Minis have webcams. Didn't want them. Maybe that was the rebelious Luddite in me tossing a sabot in the works. So I can't confirm your glitch. But I think that should give you ideas to start with.

Re: Mini 9 kernel update?

Version is

2.6.24-19-lpia

Yes, I'm running Dell-Ubuntu on my mini 9 and 8.10 is on the stick.

I let update manager install all the updates.

Setting the BIOS to default did not resovle problem

When I do dpkg-reconfigure what package do I specify?

Re: Mini 9 kernel update?

My Minis don't have webcams, so mine don't load the module for the webcam. So I can't confirm on one of my machines that the uvcvideo module is indeed the culprit, but I'm pretty sure it is and I know from checking /lib/modules/your kernel/ubuntu/media/usbvideo (the place where the module would be stored) that it is indeed uvcvideo installed on my Dell-Ubuntu mini. So its there. It just isn't working for you.

Here are some weblinks for light reading on the problem:

https://help.ubuntu.com/community/Webcam

https://help.ubuntu.com/community/UVC

Try this command from a terminal:

sudo modprobe uvcvideo

That should push into the kernel the module for uvcvideo. It should complain that the module is already installed! If it doesn't, then try your webcam. That would be the simple fix! You then just want to make sure it is included in /etc/modules.

But according to my theory, the problem is that this module didn't update when you updated your kernel. What I think is going to fix this for you is the following:

Connect to the internet

# sudo apt-get update

# sudo apt-get upgrade

That, of course, assumes you haven't been messing with your sources.list or enabling stock Ubuntu repositories in Software Sources. In Software Sources, the "Ubuntu" tab should have nothing checked, while the "Third Party" tab should have everything checked (perhaps minus only the source code lines).
