English Soul Silver Rom

Constantine and Nvidia driver







Yes, it has been around for a few days (goodbye beloved Lion, sigh) and shows some interesting features in terms of usability, whose description is easy to find on the net.

What I hope to test soon, and maybe even write two lines above, is the new management of pulseaudio bluetooth device, with the aim to make Skype calls, or VoIP in general hands-free. But the new
born (in fact, the newborn) occurs, as well as with kernel 2.6.31.5-127.fc12.x86_64, now with a nice little problem, those who are a bit 'upset by those like me who are fighting for a very simple Linux and yet very effective: the management of the Nvidia driver. The occasion of a little renewal of the fleet business (not cars, eh :-)) led me to opt for a platform on i5 suitors Intel Asus P7P55D combined with a Nvidia Gainward graphics card 216sp GTX260 1792MB DDR3 Ram , with 6 GB of RAM Corsair PC12000 1600MHz and a pair of Barracuda 7200rpm 32mb to 1 TB each (now with 650 €, looking well, takes all).
Only GTX (an animal, really) left me some concern to management, but the driver 190 (173 as well as updated) rewards promised by the handful.

OK. Assembled PC, download iso (exhaust always three versions: the x86_64, i686 and the live, even if you install only the 64-bit), DVD burn and go installation: quick, clean, in short the usual anaconda :-).

And after installing the system, the first thing I run to see what is it? But how does the booming graphics card, no?
Oh, yeah.
So go with installing yumex repo rpmfusion and that we go to take our beloved driver ....

Surprise: the classics Nvidia drivers are not there, nor in free or nonfree in, or in the update. There is only
xorg-x11-drv-nouveau, and you think: okay, will work the same, no? Have simplified everything. So try to go
ago, say, a FooBillard OpenGL or something, or Compiz Fusion: No, a desert. Maccome with the Geforce Go 7600 laptop everything is great, and with 'I'm no monster snow?
The reason is explained in his blog in Sforna Gianluca

this post.

Moral: Tap install the repo-testing and give the installation manual. So far, okay, a few more steps and lost half an hour to figure out 'is the history of the driver now, long live the open and we hope you no longer need proprietary drivers, but if those are still open for under-performing closed, at least I would expect that these were put into nonfree, update to the limit, but do not have to be stupid to seek it in testing.

the matter closed, is not that the installation is free of risk: the nouveau driver, in fact, much like the uninstall, and could lead to problems, the next time, like "what happened to the desktop manager? ".
To avoid trouble, I suggest you follow this procedure
walking, taking great care to type commands species than predicted, if it were the case of implementing it, the item "If nouveau try Refuses to Die."

To be honest, steps 2 and 3 are unnecessary, if implemented immediately after step 4 1.

Remember, to get quickly to a shell after a boot handle (the graphics drivers should do it with x11 not activated yet), just edit the kernel line of grub (grub lock the counter, select the kernel and Fedora to "e", select the kernel line and give "and") and append the number 3 to send and then "b" to boot.
Take care, precision commands, or after your beloved Dracut Linuxbox could disappear. Good Nvidia.

Forehead Turns Red Headache

Windows 7? No, thanks






7 reasons not to upgrade to Windows 7. Here they are:

Not that there were less to not get Windows XP or Vista (or myopia) ...
not I have it with XP per se, I consider, with all its limitations, historically, even for a matter of value for money, the best desktop operating system side there has ever been before completion of final 'beloved penguin (in other words, prior to 2004/2005), but Berlusconi is the evolution of the concept of using a PC that the Redmond, and not only this, is desperately trying to give that is destined to a resounding flop .
In the midst of clumsy attempts to obtain patents

globalized, the attention that the European anti-trust is giving to mergers that could prevent (hinder, not prevent) the natural evolution of important segments of the Open Source

and a widespread economic crisis

, Redmond tries to put his fingers in the holes of the dam that is about to collapse trying to prevent by all means, whether or not lawful, even against his same philosophy. We
shocks to the tail of the lizard before posting, before the final collapse.
But before accepting the fact that the "enemy" managed to be successful in a collaborative and non-impediment, I fear that information will still be a lot of blood flowed, unfortunately to no avail.

How To Build A Rolling Mirror

Fedora 11 x86_64 - Enable USB in Virtualbox 3




The inability to use USB devices within the client VirtualBox OSE is a real nuisance, having regard to the excellent features provided by this application, thanks to the guest additions, especially for those who virtualize Windows XP and the devices that are struggling to be recognized by our beloved Linuxbox.

the Debian world there are hundreds of posts that provide the solution to this problem, while for Fedora a little 'less, especially in Italian :-).

The solution I found in this

post.

Then, as I tried to apply the proposed solution and everything runs smoothly, I thought it might be useful to summarize here. console root: # gedit / etc / rc.d / rc.sysinit
edit (with #) the line 26

26 # mount-n-t usbfs / proc / bus / usb / proc / bus / usb
and add after the line
mount-t usbfs-o remount, devgid = $ (awk-F: '/ ^ vboxusers: / {print $ 3}' / etc / group), devmode = 664 / proc / bus / usb / proc / bus / usb
to obtain
24 modprobe usbcore> / dev / null 2> & 1 & & mount-n-t usbfs / proc / bus / usb / proc / bus / usb
25 else
26 # mount-n-t usbfs / proc / bus / usb / proc / bus / usb mount-t
27 usbfs-o remount, devgid = $ (awk-F: '/ ^ vboxusers: / {print $ 3}' / etc / group), devmode = 664 / proc / bus / usb / proc / bus / usb 28 fi save and exit gedit always give root console # gedit / etc/udev/rules.d/10-vboxdrv.rules and change, in line 1, the value of MODE from 600 to 660 and save

Efficient use of the restart

How To Tile Around A Shaped Tub

Fedora 11 x86_64 - Install webcam Microdia SN9C201 + OV9650





The following instructions found on the net, but I could not find them in Italian, so I thought to post it.

Type: $ lsusb
if you get a result like this:

Bus 001 Device 002: ID 0c45: 624f Microdia PC Camera (SN9C201 + OV9650)

then you have a good chance that your camera is working with this procedure :-)

First, if you are not already in the system, install git, kernel-headers, kernel-devel and ctags:

$ sudo yum install git kernel-headers kernel-devel ctags

I assume that the Fedora repository, and update the various RPMFusion are active

Now we can type, in sequence: $ git clone

http://repo.or.cz/r/microdia.git
Microdia
$ make $ cd

Now, as root: # modprobe videodev


# modprobe
v4l1-compat modprobe v4l2-compat-ioctl32
insmod sn9c20x.ko

therefore, to verify that the module is correctly loaded: # dmesg



sn9c20x: SN9C20X USB 2.0 webcam driver loaded
sn9c20x: USB SN9C20X 2.0 Webcam - 0C45: 624F plugged-in.
sn9c20x: Detected Sensor OV9650.
sn9c20x: SN9C20X USB 2.0 Webcam is now controlling video device / dev/video0
usbcore: registered new interface driver usb_sn9c20x_driver sn9c20x: [E] Empty buffer queue. To store the installation
# strip-g sn9c20x.ko
sn9c20x.ko # cp / lib / modules / `uname-r` / kernel / drivers / media / video / usbvideo / # depmod-a


procedure ends.

To operate the webcam with mplayer (I recommend pettinatevi before:-D):

For a 32-bit installation:
$ LD_PRELOAD = / usr/lib/libv4l/v4l2convert.so mplayer tv: / /-tv driver = v4l2: width = 640: height = 480: fps = 25: device = / dev/video0-vo x11

To install a 64-bit
$ LD_PRELOAD = / mplayer tv usr/lib64/libv4l/v4l2convert.so : / /-tv driver = v4l2: width = 640: height = 480: fps = 25: device = / dev/video0-vo x11

at this point it should work default with amsn.


PS If you upgrade the kernel the webcam may not work (the new kernel does not see the form).
around this problem, assuming that the files have been downloaded from the repo (Giáš­. ..), repeat the steps: $ cd

Microdia


$ make # modprobe videodev # modprobe compat-
ioctl32
# insmod sn9c20x.ko

# strip-g sn9c20x.ko
sn9c20x.ko # cp / lib / modules / `uname-r` / kernel / drivers / media / video / usbvideo / # depmod-a



Enjoy ;-)
