How To: New Mail Notification

mbooth commented on one of my last post (How To: GNOME GMail Notifier) informing that he/she uses mail-notification. I was curious to check it out for mail via IMAP and I found it way more useful as compared to Gnome Gmail Notifier. I especially like the option to configure it to check the mails every ten seconds. Thats way cool for anxious people like me πŸ™‚ Keeping in mind the huge advantages of mail-notification, I thought of writing an howto for configuring it πŸ™‚

Install Mail Notification

Installing something can’t be simpler. Just use the following command as root

[root@fedora ~]$ yum install mail-notification

Configuring mail-notification is very simple. Its as easy as it can get but there are tricks for special cases like Gmail forΒ  Google Apps hosted websites.

Launch Mail Notification

Mail notification loses a point here. It doesn’t show up in any of the menus. You have to launch it from command line. You can launch mail-notification from System -> Preferences -> Mail Notification (Thanks mbooth for correcting). Or use the following command as normal user to launch mail notification

[saini@fedora ~]$ mail-notification -p

Configure Status Icon Behaviour

On mail notification properties windows, select Status Icon tab and choose the appropriate behaviour.

Mail Notification Status Icon Action

New Message Popup Settings

Now go to Message Popups tab, and select appropriate options. If you don’t enable popups, using mail notification doesn’t really make sense (though none can prevent you from doing so πŸ™‚ ). Keeping popus stacked is good because it shows you all messages in case you get more than one new mails in an interval. Also, you can configure the expiration time for the popups.

Mail Notification Message Popups Settings

Add New Mailbox

Now select General tab and click of Add button. Mail-notification supports checking new mails from Evolution, Gmail, Yahoo! Mail, Windows Live Mail, any IMAP and POP3 Server and moreover your system mailbox πŸ™‚ Select Gmail for mailbox type. Enter username and password for Gmail account.

Mail Notification Supported Mailboxes

Mail Notification Add Gmail Account

Now move over to Details tab and set delay between checking mails. I keep it 10 seconds πŸ™‚

Mail Notification Gmail Account Settings

Add a Google Apps Hosted Email Account

This is totally optional πŸ™‚ Now we’ll add a Google Apps hosted account. This is a bit tricky. For mailbox type, you’ll have to select Gmail. For username, you’ll have to provide your email address.

Mail Notification Add Google Apps Hosted Account

Also, the mailbox name has to be modified in this case to make things work. Move over to Details tab and change mailbox name to your email address.

Mail Notification Google Apps Hosted Account Settings

Add a new IMAP mailbox (Gmail)

This is totally optional πŸ™‚ Keep mailbox type as IMAP. IMAP Server has to be imap.gmail.com . Username and password are same as Gmail Account.

Note: For this mailbox to work, you’ll have to enable IMAP in settings tab in Gmail.

Mail Notification Gmail IMAP Account

Now move over to Connection tab. Connection for Gmail IMAP has to be SSL enabled. So, select “SSL/TLS on separate port” and make sure the port number is 993.

Mail Notification Gmail IMAP Account Connection Settings

Well thats all you need to do for configuring things for getting new mail notifications lightning fast πŸ™‚ Now sit back and relax until someone sends you a mail πŸ™‚

The only major disadvantage that I found with mail-notification is that it doesn’t stay in notification area all the time. It appears only when there is a new mail.

 

How To: Configure Dual Display with ATI Radeon (fglrx)

As promised in my last post (News: ATI Catalyst Display Drivers 9.9 Released), I am back with a post on configuring dual display with ATI Radeon HD Graphics Card and proprietary catalyst (fglrx) drivers from ATI.

Hardware Used

Graphics Card: ATI Radeon HD 3200 (256MB, onboard)
Monitor 0: ViewSonic VG1930WM 1440×900 (19″ LCD, Connected via DVI port)
Monitor 1: Samsung SyncMaster 793S 1280×1024 (17″ CRT, Connected via VGA port)

Types of Dual Display

  • Mirror: Both screens have same content, identical refresh rate and resolution.
  • Clone: Both screens have same content but refresh rates and resolutions can be different.
  • Horizontal: Both screens can have different content, refresh rates and resolution. Screen 1 is left or right of Screen2.
  • Vertical: Same as horizontal. The only difference is that Screen1 is above or below Screen2.

In this post, we are interested in Horizontal setup with xinerama on. This way we can have two desktops allowing full screen modes on both of them and allowing us to drag and drop windows from one screen to the other.

Install ATI Drivers

If you don’t have ATI drivers installed already, follow this How To: Install ATI Catalyst (fglrx) Drivers on Fedora 11 (works for any version of ATI Catalyst drivers).

Generate xorg.conf file

If you don’t see the xorg.conf file at /etc/X11/xorg.conf, then you need to generate it to proceed to next step. Use the following command as root to generate one

[root@fedora ~]$ Xorg -configure

This command will generate the default xorg.conf file at /root/xorg.conf.new. Copy it to /etc/X11/xorg.conf.

[root@fedora ~]$ cp /root/xorg.conf.new /etc/X11/xorg.conf

Backup xorg.conf file

Backup your original xorg.conf file so that you can restore it in case the configuration doesn’t work the way you expected.

[root@fedora ~]$ cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Generate Configuration for Dual Display

Now we are ready to generate the configuration for dual display. Use the following command with appropriate arguments (in accordance with your hardware configuration)

# --screen-layout will place second screen on left of your first screen. Other possible values are right,above,below.
# --xinerama=on option enables you to have two different desktops and one of them being passive.
# You can drag and drop windows from one desktop to the other. Task bars appear only on one of the desktops.
[root@fedora ~]$ aticonfig --initial=dual-head --screen-layout=left --xinerama=on
# --resolution=_screen_number_,widthxheight
[root@fedora ~]$ aticonfig --resolution=0,1440x900 --resolution=1,1280x1024
# Set horizontal sync and vertical refresh rates for both monitors.
[root@fedora ~]$ aticonfig --hsync=0,30-60 --hsync=1,30-60 --vrefresh=0,30-60 --vrefresh=1,30-60

You can download my xorg.conf file via this link.

Reboot or Logout and Login Again

If you just setup your ATI drivers and configured the dual display, you need to reboot so that fglrx module can be loaded properly. If you rebooted after setting up the drivers, just logout and login again to checkout your dual display πŸ™‚ If everything works fine, say thanks to me and if not blame ATI πŸ˜›

Adjust DPI for Normal Font Size

I faced a problem with my font sizes being too big while using xinerama. It was easy to fix by adjusting DPI. Go to System -> Preferences -> Appearance. Go to Fonts tab. Click Details located near the bottom right corner. On that window, try descreasing the “Dots Per Inch” value. Mine worked fine with 85 DPI.

Below is an image of my dual display setup. Click to enlarge.

How To: Recover Deleted Files in Linux Using Photorec

Frequently I get messages like “I have accidentally deleted my project. Is there any way to recover it in Linux?” or “I worked really hard on that program and managed to deleted it right before submission πŸ™ How do I recover?”. Well I didn’t really have any idea on “How to actually recover deleted files in Linux”.

A few days back I was designing the new logo for Videocache in Inkscape. After finishing the design, I saved the svg file carefully. And deleted other images which I embedded in the logo. A few moments later I realized that I just screwed up myself by deleting all those files as the svg file is now good for nothing.

I searched a lot on recovering files in Linux but in vain. Then a friend (bitgeek) told me about Photorec. I managed to recover all the files using photorec. I thought it would be a good idea to let others know and spread a good word about Photorec. Below is a step by step howto on using Photorec to recover your files.

What is Photorec?

From Photorec website,

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its ‘Photo Recovery’ name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media’s filesystem has been severely damaged or re-formatted.

For This HowTo

Lets say I had a file download_arrow.png in /home/saini/Desktop which I have removed accidentally. Login as root and create a directory recover which will be used to store all the recovered files.

Install testdisk/PhotoRec

Photorec comes as a part of testdisk package in Fedora (I hope its same for other distributions as well). Use yum to install testdisk.

[root@fedora-tips ~]$ yum install testdisk

Launch Photorec

Once you are done with installation. Open a terminal and launch photorec (as root).

[root@fedora-tips recover]$ photorec

Select Hard Disk

If you have more than one hard disk in your system, select the one from which you have deleted the file(s).

PhotoRec Hard Disk Selection

Select Partition Type

If your hard disk has Linux partitions, then select [Intel].

PhotoRec Partition Selection

Select Filetype Option

Move to [File Opt] and press enter. Here you can disable all file types by pressing ‘s’ . Use space to toggle the check button. Now since we removed a png file, we are going to check only png file type.

PhotoRec Filetype Selection

Select Options

Photorec also has a list of different options. Under normal circumstances you don’t need to modify them

PhotoRec Option Selection

Select Partition

Move the selector to the partition from which you have removed the file. Then press enter on search.

PhotoRec Partition Selection

Select Filesystem Type

If you are using Linux, its going to be ext2/ext3/ext4. So the default selection is file.

PhotoRec Partition Selection

Select Space for Analysis

Select free if you didn’t write to that partition after removing the particular file otherwise select whole.

PhotoRec Space Selection

Select a Directory to Recover Files

Now select the path where the recovered files will be stored. Then press ‘Y’.

PhotoRec Recovery Directory Selection

Recovery Progress

Photorec will show how many files it has recovered.

PhotoRec Recovery Progress

All recovered file will be stored in the directory selected above. Open them in a file browser and you’ll get the removed file there. I hope this howto will help you recovering files you accidentally delete πŸ™‚

 

MSN Crawlers Pawned

After seeing the way MSN crawled my last post, I just realized why Microsoft could never do good in Search Engine Market πŸ™‚

I wonder why MSN would crawler same page from two different machines. I wonder if a single page can be divided further for crawling. Checkout the screenshots below πŸ™‚
