How to Enable the Systray Whitelist in Ubuntu 13.04

If you are anything like me, you used to enjoy whitelisting applications like checkgmail and rssowl.  Then, the change was made with Raring that we could no longer whitelist applications.  This can be difficult when your favorite programs do not use Ubuntu indicator applets.  If you want your ability to whitelist back, there is a PPA that comes with Unity patched to re-enable the systray whitelist.

The commands you need to type are:

sudo add-apt-repository ppa:timekiller/unity-systrayfix

sudo apt-get update

sudo apt-get upgrade

Once you do this, you then need to type Alt + F2 and type in “unity” (without the quotes), or log out and back in.Then open dconf-editor and navigate to com > canonical > unity > panel.  The systray whitelist should be there, so you can enable apps.

Remember to restart unity after you have added applications.

grep -R doesn’t automatically search amazon

The following bug report landed on Launchpad four days ago, courtesy of akeane:

Dear “root owning” overlords,

When using grep recursively I only get local results:

grep -R fish_t /home/noob/fish_game/*

/home/noob/fish_game/fish.h: struct fish_t {
/home/noob/fish_game/fish.c: struct fish_t eric_the_ fish;

or worse:

grep -R shark_t /home/noob/fish_game/*

/home/noob/fish_game/fish.h: struct shark_t {
/home/noob/fish_game/fish.c: struct shark_t_t mark_sw;

I declare this a bug for two reasons:

1. The output is boring.
2. The terminal has more than 2 lines!!! It’s an unefficient use of my screenspace.

I believe the reason for this is that the grep command only searches locally for things I am actually looking for, I kind of expect the results I get from my codebase and as such it removes any sense of mystery or something new and exciting to spice up my dull geek existence. That’s boring, grep -R should also search amazon, so I get more exciting results such as:

This is less dull and also maximises the use of my terminal and hence increases my productivity.

Please can you change the grep warez to have this feature, and just install it on my machine while I’m down the pub, after all you do “erm, have root”, so it should be easy for you to do 🙂

Thanks Ubuntu devs!!!

Please forgive me for not summarizing. The entire thread is worthy of note, as well. I only pray it doesn’t disappear.

I have to admit, though – once you get over the weirdness of searching for “cat food” (without the quotes” in the Unity dash, Amazon results can be useful.  😉

Natty Narwhal Beta 2 Is Now Available

Natty Narwhal Beta 2 is now (as of April 14) being made available through the home page.

Let me point out some of the changes made with Natty. The most obvious is the launcher on the left, containing several buttons for folders and applications and the Ubuntu Software Center, among other necessities. Here is a screenshot to show the general layout:

The top bar no longer allows widgets – it is used instead for the list of menus that used to be part of each separate application screen. I am suffering from withdrawal because I used to use the top bar for everything from monitoring my CPU to launching applications.

Another thing that is gone is the notification area. This means that, for example, checkgmail no longer works. I am presently trying cGmail, a program that uses the notification area. The problem with it is that it only shows notifications when the e-mails arrive. There is nothing on the screen afterwards to warn you that you’ve got a boatload.

If you click on the Ubuntu logo on the top left of your screen, you will find a group of shortcuts, including Check Email (for Evolution), Find Files, and several AOos choices. Unfortunately, when I tried to get a screenshot of that page, when I left-clicked on the screenshot button on the launcher, the shortcut page disappeared. 😦

The Applications search button pulls up an intelligent window. At first, I was worried that every time I wanted to run a particular app, I would have to go through 173 applications to find it. Thankfully, as you keep using the game or bleachbit or whatever else you want, it will start showing up among the most used.

Natty is running more slowly on my $300 computer (with some modifications) than past versions have done. I don’t know if this slowness will be fixed by release time or not.

I’m not sure I am ready to recommend Natty Narwhal. It looks like a great system for a young child whose parents can set up the most used areas, and add buttons to the launcher for the child’s favorite applications. It feels very much like a netbook interface.

If you do decide to upgrade to Natty, this is probably the time to do it. Natty is stable enough to use. It can at present be downloaded from the start page, as I noted earlier. If you are running Maverick, you may wish to go with the Alt + F2, type in update-manager -d, method of upgrading. I did a clean install because I had extra PPAs I was using, and wanted to clean up my machine.

Natty Narwhal Alpha 1 Has Been Released

On Thursday, December 2, 2010, Natty Narwhal Alpha 1 was released. This is a developer snapshot to give an early glance at the next version, as well as to test it.

To upgrade from Ubuntu 10.10 on a desktop system, press Alt + F2 and type in “update-manager -d” (without the quotes) into the command box. Update Manager will let you know: New distribution release ‘11.04’ is available. Then you just need to click on Upgrade and follow the instructions.

This release is labeled for developers only. It is far too early a release to be used on production machines. For Ubuntu Desktop and Server, the list of source ISOs is here. I recommend choosing a torrent. Transmission makes torrents easy to add to the download list. If you use a torrent, please consider letting people upload from it for a while after you have finished downloading.

Unity is now the default for the Ubuntu Desktop session. This is only partially implemented. The Unity Launcher is available. It can be used to launch applications that are pinned to the launcher and also to switch between applications. For now, clicking the Ubuntu logo in the upper left of the screen will open the applications directory. This is temporary until the Applications place is available.

Network Manger applet has been patched to use appindicator. Classic Gnome panel applets are not supported in Alpha 1, only indicators.

There are now two kinds of sessions in GDM: Ubuntu Desktop will run Unity by default, and the Ubuntu Classic Session will run gnome-panel. Ubuntu Classic supports all video hardware and video drives. Ubuntu Desktop requires 3D driver support.

Alpha 1 includes the Linux 2.6.37-rc3 kernel which is based on the latest mainline release candidate kernel. This is expected to roll forward to version 2.6.38 for final release.

Please note for installation: the live CD configurations are being reworked for Natty. At this time, the images are a bit too large to fit on a CD. You are advised to use a USB stick or DVD as a workaround.

I will not be upgrading right now, because I have Christmas card address labels to print. Normally, I run my computer for testing so others don’t have to. Right now, it is a production machine. 😉

Ubuntu 11.04 to Move to Unity

Jono Bacon of Ubuntu fame has posted in an article that Ubuntu 11.04 (Natty Narwhal) will be shipping with Unity instead of Gnome Shell. Unity was already shipped on the Ubuntu Netbook Edition in Ubuntu 10.10 Maverick Meerkat. Bacon claims that “users and OEMs have been enjoying the experience.” I don’t know about OEMs, but I’ve read articles by users that have said they will stay with Ubuntu 10.04 Lucid Lynx until 11.04 comes out, so that the bugs in Unity will hopefully be fixed.

Actually, I can say something about one OEM, System 76. Their starting netbook is still shipping with Lucid. ZaReason’s netbook, on the other hand, is shipping with Ubuntu Netbook Edition (with Unity) as an option.

Bacon stressed in his post that Ubuntu is still a GNOME distribution, shipping GNOME apps. As he posted, “The only difference is that Unity is a different shell for GNOME, but we continue to support the latest GNOME Shell development work in the Ubuntu archives.”

I plan to run Natty Narwhal Alpha 1 in Testdrive, and will see if Unity is already the default shell at that time.
