Sina's questions

I have a T440p and using it with two external monitors connected through VGA and Mini-Displayport (one vertical, the other horizontal, both 1920*1080) and not using the laptop display itself. I also don’t use a dock and my monitors are connected to laptop directly. I'm planning to buy an ultra dock.

After searching a bit just saw lots of issues with using both VGA and HDMI ports on dock to use two monitors simultaneously. Since nearly all of these threads were older than a year or so, I wanted to check if what I'm trying to do is possible or still there is a problem with that.

I use ubuntu 12.04 LTS, but if upgrading to 14.04 LTS will solve the problem I can do that.

I've been using jdk6 on ubuntu 12.04. I was trying to update my jdk to 7. I installed jdk7 and also removed jdk6. Now my javac version is 1.7.0_03. but my java version is still 1.6.0_24. So I got UnsupportedClassVersionError while trying ro run my java project. How can I update my java?!

I'm trying to send an email using mutt like this:

echo 1.txt | mutt [email protected] -s Hello -a file.tar.bz2

It's getting no error, but I didn't receive the email. What's the problem?

How I can set a keyboard shortcut to access the Applications or Places menu in gnome classic on ubuntu 12.04?

I'm using ubuntu 12.04, with gnome classic. I was using it with no problem. Then after I logged in once I saw 4 bars at the top of the screen and 4 at the bottom instead of 1. How can I fix it? I tried removing and reinstalling gnome-panel. But it didn't work.
