Karabiner on Mac have this great feature, it can map a single key with two different featuers, I'm wondering if I can do this on ubuntu.

The feature is that it can map enter to control, and when you "click" enter, it will send enter, but when you hold enter, it will send control. Also you can set a timeout if you want, then enter will only be control during the timeout. After that you'll get enter.

Same thing can do on other keys, I can map right command as enter when it is only pressed once, but it is still command if I hold it.

Is there any software which can do this in ubuntu? or better if there is a generic linux solution.

I understand MATE is a desktop environment, but what is the difference between ubuntu with a MATE desktop environment and ubuntu-mate ?

EDIT: Difference Between Ubuntu and Ubuntu-Gnome is not a duplicate of my question because there is a dedicated distribution called ubuntu-mate

Is there an easy way to check a notebook's hardware compatibility with ubuntu before you buy it?

I really don't want to buy a notebook home and find several bugs caused by the hardware.

I know that DELL has some notebooks which are pre-installed ubuntu12.04LTS, i.e. the new xps. But what about other notebooks? isn't there a way to quickly check a notebook's compatibility with ubuntu?

A way I can see is using a LiveCD/ubuntu stick and boot in ubuntu first, then run some tests. But the problem is: how to make these tests in a short time automatically??? and how can I check the hardware compatibility? I know that I can use lshw or hardinfo to get informations, but only having the information is not enough, there are still some possibilities that your hardware has a bug. For instance, Lenovo T410i's wireless driver has a bug which causes extremely low speed internet connection, I googled a lot and recompiled the driver to fix that bug. So this is the kind of situation I'm trying to avoid.

Any help is appreciated.

When setting the channel to wlan0, I get an error:

SET failed on device wlan0 ; Device or resource busy.

I tried to shutdown wlan0 by:

sudo ifconfig wlan0 down

and wlan0 did not appear in the ifconfig result, but I still get the error when I use this command to switch channels:

sudo iwconfig wlan0 channal 1

The funniest thing is I just used this method to change channal from 4 to 6, and now I want to change the channal from 6 to 1, but I can't finish it. Did I miss something?

Is there a way which could let me know all the file status by just looking at the folder view, like what TortoiseHg, TortoiseSVN, TortoiseGit did on windows?

Now my git repo folder looks the same as other folders. If I want to view file status I have to type git status in the command line. I want some icons which could inform me the file/folder status at my first glance on the folder view.

I'm using Ubuntu 12.04

EDIT

I googled it, and what I'm asking for is called the overlay icon.
