Dropbox issue on Fedora 17

If you use Dropbox, you may get this annoying message in the bottom notification area.

Unable to mount filesystem. Please run: “echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches”

Issuing the proposed command, you will only fix the problem up to the next reboot. A better solution is therefore to set the maximum number of user watches in a system configuration file.

So open the file /etc/sysctl.conf (for example using vim)

$ sudo vim /etc/sysctl.conf

and add the following line

fs.inotify.max_user_watches = 100000

Reboot and you’re done.

PS 1. If for any reason you still don’t use Dropbox, please be aware that you should! Using my link for registration, you will gain a bonus of 500 MB in addition to the regular 2 GB account.

PS 2. Are you still waiting? Create a Dropbox account! 😉

SD card reader on Fedora 17

So you installed your Fedora 17 and your SD card reader is not working any more.

Interesting. Maybe you have as me a Realtek SD card reader, that on lspci looks like this:

generoso@jk-laptop> lspci | grep Unassigned
03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5209 (rev 01)

Good for you, since you have simply to go here, download the right driver source archive and extract it in a folder. Then you have to compile and install it as described in the README file.

1) make
2) make install
3) depmod
4) reboot your computer

Note that for steps 2 and 3 you need to be root.

Note also that, in order to be able to compile this code, you probably need to install the development package for building kernel modules.

generoso@jk-laptop> sudo yum install kernel-devel

And that’s it.
Now I can finally get from my SD card the photos of my last trip in Tuscany.

My random notes…

My name is Generoso. I’m a computer engineer and a guitarist. I’m Italian, but currently I live in Grenoble, France.

I’ve always liked those cool guys finding solutions to everyday computer problems and sharing them on the net. I’ve always liked this kind of open philosophy. And not only for computer stuff.

So, after finishing that delicious Sachertorte a friend prepared for me, I decided to start this blog. Basically, I just want to note some random stuff I find useful or interesting, hoping it actually is useful and interesting for someone.

About me.. I like technology, music, travels, psychology and chocolate.
