Webcam + Skype 2 = Ubuntu show-stopper

Webcams don’t seem to work, and Skype is only on version 1.

The result? Back to Windows I go.

My girlfriend lives in Gothenburg, and I live in London. Our primary means of communication is Skype 2.x plus Logitech webcams.

Using this setup we speak to each other at least 30 minutes every day, sometimes more, and we go to see each other too. It’s a very important thing for us, being able to stay in touch so much and with visual as well as audio… long distance relationships are really tough anyway, so anything that can help I’ll use.

Anyhow, couldn’t find any successful drivers that would work in Ubuntu for the Logitech Quick Sphere webcam that I have. And further investigation into Skype on Ubuntu (ignoring the fact that it never worked with AMD64) reveals that it’s just the old version, minus webcam support. So… if I could get the webcam to work, I still wouldn’t have had Skype working with it. I’ve tried Skype 2 on Crossover and Wine, but neither were successful.

Ah well, good thing I didn’t wipe Windows :) A quick change to grub is all that’s needed to be back in the Windows world, hoping that this time I don’t see blue screens. And maybe, just maybe, the next time I give Ubuntu a whirl, the webcam + Skype thing will be sorted. Until then, I’m going to stick with what works.

The morning after an Ubuntu installation

Ubuntu is up and running, but it wasn’t all quite as simple as it should’ve been… so here are the list of things encountered and how I got around them.

#1 Screen Resolution

During installation you are prompted for which screen resolutions you want to use, however there are two blocks of text… the top one implies that marking a resolution will ‘remove it’ from your system, and the lower one-liner implies that marking a resolution will ‘add it’ to your system.

Initially I followed the first and didn’t mark anything… bad idea… then you get virtually nothing available except for three default modes.

The key is to mark all of them, at least that way you get the choice.

To repair xorg and to make the other screen resolutions available you can do this:
1) Stop xorg (this will drop you to a command line):
sudo /etc/init.d/gdm stop

2) Reconfigure xorg (note that it helps if you have your monitor’s Vertical and Horizontal Sync numbers available):
sudo dpkg-reconfigure xserver-xorg

3) Fire up xorg again:
sudo /etc/init.d/gdm start

I found that information here:

#2 Skype

I couldn’t get Skype and a few other programs working under Ubuntu AMD64 at all. Instead, install Ubuntu i386. Yes, it’s not so nice to have a 64-bit CPU and then install a 32-bit Operating System, however you’ll notice immediately that there is far more software available on i386 and it’s far less buggy… even Easy Ubuntu loves i386 but not AMD64.

#3 Grub Error 17

I have three harddrives installed:

Disk /dev/hda: 120.0 GB, 120000061440 bytes
255 heads, 63 sectors/track, 14589 cylinders

As you can see, hard drive 1 is Windows, hard drive 2 is Ubuntu, hard drive 3 is an NTFS disk full of files.

During installation of Ubuntu I disconnected the NTFS disk of files, as that and the disk I was putting Ubuntu on are the same make and model and I was afraid that I might overwrite the wrong volume.

So… disconnected hard drive 3, installed Ubuntu on hard drive 2… and it worked :)

Until I re-connected hard drive 3.

It turns out that this was because hard drive 2 (Ubuntu) was actually plugged into the mother board in SCSI5. Hard drive 3 (NTFS files) was plugged into SCSI2. All looked fine in the BIOS but once grub has started up, it recognised hard drive 2 as /dev/sdb2, but grub expected to find the /boot partition on /dev/sdb1.

The solution was simply, plug Ubuntu into a lower numbered SATA (SCSI by appearances) socket. So I moved Ubuntu to SCSI1 and grub worked perfectly.

#4 Accessing Windows and NTFS partitions

Couldn’t figure out how to do this at first, but the answer is over here:

So that’s everything up and running… well, the basics. Next up is seeing whether the webcam will work, figuring out what to do with email (I used The Bat! before and I’d like to use it again, but there is no Linux version… so it may be a case of using Wine).

Nope, that’s it… I’ve had enough of Microsoft Windows!

My computer crashed today. It wasn’t the first time, I’ve been seeing blue screens quite often recently. Usually when all drives are in use and I’m on the internet. Lord knows what that might be.

I’ve run memory checks, all fine. I’ve checked disks, all fine. I’ve even got hold of the Ultimate Boot Disk and check everything that is checkable (much zen is to be found in watching ASCII progress bars check things)… all fine.

So what can it be?

Well the blue screens all indicate that I’m getting the dreaded and vague IRQL_NOT_LESS_THAN_OR_EQUAL.

Googling around seems to suggest that this isn’t a bug. Oh no, instead it’s attributed to bad drivers in older hardware and Windows XP bombing out on those. I really don’t buy this though, I would be hard-pushed to identify any part of the machine older than 24 months (the mouse? the monitor?), and nothing that is really going to be an obvious candidate.

Windows was only rebuilt recently so I’m not going to go down that route again… it’s tiring, I just want the thing to work.

So… it’s a lovely day, I can’t cycle, and my girlfriend is in Sweden whilst I am in England… what’s a man to do with his time other than to format one of his drives and install a copy of Ubuntu? Nothing, that’s what.

Actually I’m looking forward to giving Ubuntu a serious whirl on this machine. The hardware is lovely and was purchased with a move to Linux in mind and not Windows XP (the AMD 64 chip will now actually see full use for the first time).

So in around 20 minutes I’ll have finished clearing out the spare drive, will perform a quick backup, and then reboot for an Ubuntu install. Expect an update in a few hours posted from Firefox in Ubuntu :D
