MSI WIND Webcam for Fedora 9

MSI WIND has an integrated webcam, to configure it on Fedora 9 you’d better  have the latest firmware installed, available from MSI website. I’m not sure that this is actually required, but this is my configuration.

Check now that you have an uvcvideo kernel module installed:

lsmod | grep uvc

you should get something like this:

uvcvideo              49928  0
compat_ioctl32    5120    1   uvcvideo
videodev              29824   1   uvcvideo
v4l1_compat       15876   2   uvcvideo,videodev

If such, your webcam is probed but not correctly configured. To do so, type:

rmmod uvcvideo

modprobe uvcvideo quirks=2

You can test that everything works by using mplayer to display the webcam output:

mplayer -fps 15 tv://

Now, you can make changes permanent by editing /etc/modprobe.conf to add this line (the file does not exist if you have just installed the system, so create it):

options uvcvideo quirks=2

and test that works at the next reboot.

Install Fedora 9 on a MSI WIND

I’ve recently bought an MSI WIND U100, it came with a pre-installed Windows XP and I started to install Fedora 9 on it, I will keep Windows as it could be useful in some environments, but my interest is in having Fedora running.

First step is in installing Fedora over it, the 80 GiB disk conveniently ha three partions, the first is for recovery, the second has Windows XP, so I splitted the third for a tiny boot partition (which is requested by Anaconda, altough BIOS is capable of booting from anywhere) and a large LVM volume, where I carved out a root partition and an encrypted home partition, a security wise solution as it’s a notebook which means that has the tendency to be shipped away from its legitimate owner. The LUKS passphrase used for the home directory was strong, so I can use a weak and distinct password for the system user.

Installation requires a Fedora respin that you can find here. I picked up a USB pen drive, then I use the livecd-iso-to-disk (yum install livecd-tools) to make it bootable. The process does not destroy any data on it, and at the installation prompt I gave linux askmethod, to choose the installation source (I opted for a HTTP based installation).

The installation went smooth, later I customized the system to have compiz installed (I can made very impressive presentation with it!) and updates are flowing. The only problem I’ve noticed is that sometimes on boot the system hangs at the ACPI discovery phase, don’t know why.

Disabling Firefox “Download Completed” notifier

It’s the clumsy, irritating window-ish and useless pop-up that appears on the right bottom corner after a download is completed.

It’s useless, because I can monitor downloads by opening a file manager window in another workspace. It’s irritating because when it appears, it prevents my to click on the workspace switcher (usually I have Firefox open on a workspace, and move to others when needed).

Thankfully, it could be disabled, by entering about:config on the address bar, then searching for and setting it to false.
