Enter SSH passphrase once

Before upgrade

When I was running git clone git@... (using ssh) once per computer restart a window dialog appeared containing a textbox for inserting my SSH passphrase and confirmed with OK. Then the passphrase was no longer required until the next start of my system.

After upgrading to 13.10

After upgrading to Ubuntu 13.10 that window doesn't appear anymore but a message in terminal appears:

Enter passphrase for key '/home/username/.ssh/id_rsa': 

...every time when cloning a git repository this appears.

How can I fix this? I want to enter my passphrase only once.

what happened to json_encode in 13.10 php?

Just updated to saucy 13.10 and json_encode is missing from the bundled php. json doesn't appear in the phpinfo() output and i'm getting this error in my app:

PHP Fatal error:  Call to undefined function json_encode()

Anyone else experiencing this or know the fix?

Time is not displaying in the Top Bar

I'm running Ubuntu 13.10 with dual boot along side Windows 8.

The top panel or bar doesn't display the time.

When I open the Clock menu, all the settings over there are grayed out
(Settings -> Time and date -> Clock)

I tried other methods (like dconf) but that didn't work.

Ubuntu Server 13.10 now goes to sleep when closing laptop lid

I recently upgraded to the latest version (13.10). I have it running on an old laptop. Since the upgrade, whenever I close the laptop lid, it goes to sleep mode.

Any idea on how to fix?

I've tried the solution here:

Keep Ubuntu Server running on a laptop with the lid closed?

After installing acpi-support I don't have the file: /etc/acpi/event/lidbtn to edit.

Your help is appreciated!

Invalid argument - Brother scanner not working after upgrade (brscan2 driver)

I recently upgraded Ubuntu 13.10 (Saucy).

Scanning via my MFC-420CN had been working in Ubuntu and Linux Mint installs up though Olivia and Oneric. However once I upgraded from these, scanning broke. I installed a fresh copy of saucy to verify that it wasn't just something to do with the upgrade.

Brother's website has a notice that all brscan1 models no longer support usb scanning as of Ubuntu 11.10, but it doesn't seem to apply for brscan2 and brscan3 models. Moreover I found several other posts that seem to indicate at least brscan4 models are currently working. However I have been unable to verify scanners using brscan2 (or other divers other than brscan4) and ubuntu 13.10 (actually 12.10 and greater) are currently functioning.

For cross-referencing / to help others with the problem the complete list of brscan2 scanners is as follows:

_{DCP-110C DCP-115C DCP-117C DCP-120C DCP-130C DCP-135C DCP-150C DCP-153C DCP-155C DCP-310CN DCP-315CN DCP-330C DCP-340CW DCP-350C DCP-353C DCP-357C DCP-540CN DCP-560CN DCP-7010 DCP-7020 DCP-7025 DCP-750CW DCP-770CW DCP-8060 DCP-8065DN MFC-210C MFC-215C MFC-230C MFC-235C MFC-240C MFC-260C MFC-3240C MFC-3340CN MFC-3360C MFC-410CN MFC-420CN MFC-425CN MFC-440CN MFC-465CN MFC-5440CN MFC-5460CN MFC-5840CN MFC-5860CN MFC-620CN MFC-640CW MFC-660CN MFC-665CW MFC-680CN MFC-685CW MFC-7220 MFC-7225N MFC-7420 MFC-7820N MFC-820CW MFC-845CW MFC-8460N MFC-8660DN MFC-8670DN MFC-885CW MFC-8860DN MFC-8870DW MFC-9420CN}

Similar previously asked questions / problems (but for brscan3 driver hardware):

• After upgrading to 12.04 the scanner from Brother Printer MFC-290C does not work
• xsane exits with "Invalid argument" while scanning with Brother DCP-J725DW, what does it mean?

So far I've tried:

• Installing sane-utils

• irections at brother's website regarding the brscan2 install, including using the dpkg -f flag

• editing /lib/udev/rules.d/40-libsane.rules to include

code:

# Brother scanners

ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

• copying files form lib to lib64:

code:

cd /usr/lib
ln -s ../lib64/libbrscandec2.so.1.0.0 .
ln -s ../lib64/libbrcolm2.so.1.0.1 .
ln -s ../lib64/libbrcolm2.so .
ln -s ../lib64/libbrscandec2.so.1 .
ln -s ../lib64/libbrscandec2.so .
ln -s ../lib64/libbrcolm2.so.1
cd sane
ln -s ../../lib64/sane/libsane-brother2.so.1.0.7 .
ln -s ../../lib64/sane/libsane-brother2.so.1 .
ln -s ../../lib64/sane/libsane-brother2.so .

• installing ia32-libs and repeating the sane-utils install
• removing the 64 bit brscan2 driver and replacing it with the 32 bit one, but results of scanimage with the 32 bit driver set-up for usb or network mode were less than promising:

code:

# scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

• of the 32 bit windows drivers with WINE eumlating Win2000 or XP -- it almost completes in 2000.

Debugging 64 bit drivers:

With brscan2 installed I can open up simple-scan and find the scanner; moreover scanimage output indicates that everything is okay:

# scanimage -L
device `brother2:bus5;dev2' is a Brother DCP-350C USB scanner

But scanning (even as a root user) still doesn't work.

> sudo scanimage >image.pnm
scanimage: open of device brother2:bus2;dev4 failed: Invalid argument

xsane produces a similar error:

 Failed to start scanner: Invalid argument

sane-find-scanner produces a pipe error shown here: http://pastebin.com/tTNMyD1m but that seems to related to the fact that brother is providing the driver, not sane.

I'm pretty stuck at this point, any help would be appreciated.

Chrome won't start from the launcher

I have Ubuntu 13.10 64-bit and chrome 64-bit.

I can start chrome from the command line with google-chrome-stable and lock it to the launcher, but when I try to launch chrome from the launcher nothing happens.

What do I have to do to make chrome working with the launcher?

phpStorm losing keyboard input

Every now and again phpStorm will lose input from my keyboard. I can still click around, but it will not register any keys. Other windows are fine. It takes a phpStorm restart to bring them back. It seems to happen most when I Control+Tab between open tabs

I am running: Ubuntu 13.10 phpStorm 7.1 JRE 1.7.0_51

Nautilus doesn't allow adding/removing bookmarks

I just did a fresh install of Ubuntu 13.10 (actually, I've done two fresh installs, hoping that trying again would get this working).

I don't seem to have the ability to add or remove bookmarks from Nautilus. The ones that are there by default (Home, Desktop, Documents, etc.) work fine. I can right click on them and rename them. However, I cannot remove any of them. The option is there "Remove" but disabled/grayed out.

The same is true if I try to add bookmarks. I go to "Files -> Bookmarks", and all the bookmarks show up, but the buttons at the bottom to add, remove, or re-order the bookmarks are simply disabled.

What am I doing wrong?

persist port routing from 80 to 8080

I use amazon EC2 instance which works via ubuntu. By default according security restrictions I can't bin my application to port 80, so I just bind it port 8080 and then set routing redirect from port 80 to 8080 via the following command:

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 8080

But I found that when I reboot the server this settings no longer active untill I invoke this command again.

So my question is how to enable port's redirect work even if system was rebooted?

htpasswd executable is missing

I'm running 13.10. Clean install. Ran: sudo apt-get install apache2

I would expect that I would have htpasswd in the /usr/sbin directory along with the apache2 executable. I don't.

I can provide any info necessary.

Where are gedit's preferences?

This is incredibly weird. I don't see "preferences" in any of my gedit menus. I'm running Version 3.8.3. All I want to do is show line numbers, but I can't do that without preferences.

Where the heck are they hiding?

note: I did remove indicator-appmenus because I dislike having the menus detached from the window.

2015 Update: somehow this is being flagged as a dupe of Enable line numbers in gedit which is a little confusing. The solution is the same but the questions are different.

How to fix missing libudev.so.0 for Chrome to start again?

Trying to start chrome yields in following error on the command line:

/opt/google/chrome/chrome: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory

The error first appeared in Ubuntu 13.04, I tried purging and reinstalling Chrome. It persisted after upgrading to Ubuntu 13.10.

Unable to use IntelliJ IDEA keyboard shortcuts on Ubuntu

I am very new to Ubuntu, and I'm having a problem that I don't know how to get it fixed. I even tried looking it up on the web for answers, but maybe I don't know the right terms to search for it.

I work with IntelliJ IDEA, an application for development. And I am very used to the keyboard shortcuts, but when I made the switching from Windows XP to Ubuntu 13.10, some shortcuts don't work anymore. For example, such as;

• Ctrl + Alt + <(Left arrow)
• Alt + F8

Is there any reason as to why? and are there any fix for this? Or maybe just something to guide me on my searching

Thank you all very much in advance.
