Problems in Viewing Docx On Ubuntu?

After having a lot of trouble in viewing Docx, I installed odf-converter-integrator from http://katana.oooninja.com/w/odf-converter-integrator/download . This helped a lot although the output was not perfect.

Logging into Ubuntu from another Ubuntu Machine and View Remote Display

Lets call the machine on which we want the display to be shown as client machine, and the machine from which the display will be shown as the server machine. 

SSH supports X forwarding. To enable X forwarding on the server, first install ssh using 

sudo apt-get install ssh

Then, edit /etc/ssh/ssh_config to set 

ForwardX11 yes

On the client, you need to start a new X server by running: 

sudo xinit -- :2

Then on the client, run 

ssh -X server -l user 

After logging in onto server via ssh, do "echo $DISPLAY". This variable should have been set by ssh. Then run "gnome-session" on the server. You can now see it displayed onto your client. 

Do "Ctrl+Alt+F7" to go back to the X server working with your client, and "Ctrl+Alt+F8/F9" to toggle to the display received from the server.

After logging into the server, you might get errors like: 

/usr/bin/xauth: error in locking authority file /home/user/.Xauthority.

The following resolved the issue for me: 

xauth -b quit

Hudson on Ubuntu

Worked fine for me, except that Hudson has a dependency on Java. For installing Java I followed:

Installing KDevelop4 on Ubuntu 10.04

Follow http://www.kubuntu.org/news/kdevelop-4. It worked fine for me. After this, I installed the vim plugin, ooh la la.

Process Getting Killed Using Ubuntu 10.04 as VMWare Guest OS

I installed our memory-intensive software on Ubuntu running on VMWare. This process was getting killed quite quickly after start. After some internet search, I understood that this is due to the OOM-killer in the kernel. To disable to OOM-killer, I added to my /etc/sysctl.conf:

vm.oom-kill = 0 

I got this and a lot of other useful information related to oom-killer from this forum. But most of what is said there regarding oom-killer configurations does not apply to Ubuntu 10.04.

Recovering Windows Data After Crash

This must be familiar. My lab's Windows Vista crashed suddenly without reason and would not boot up again. Fortunately I had backed up my data (using Windows Backup) on a separate disk drive. I used an Ubuntu Live CD to boot and then I was able to recover data from zipped files from where windows had backed it into zipped files. Perhaps not surprisingly or surprisingly, I was unable to mount and access the disk drive that previously ran Windows.

Profiling Java Application with Netbeans on Ubuntu

Currently this requires installing the "Java Profiler" plugin from within the IDE > Tools > Plugins. Then follow the same steps as for profiling in Windows.

Ubuntu Update to 10.04

Every time I upgrade the Ubuntu version, I am faced with one or more issues. This time the audio and video worked fine and the desktop looks are much improved. The bootup is much faster. There is a new chat interface integrated with the desktop, which is cool, as is Ubuntu One.

However I faced the following issues. I upgraded on my desktop computer as well as my laptop -- so the list of issues is a merged list of the issues with both the laptop and the desktop.

1. gcc compile output messages miss the names of the variables after the upgrade. After a lot of failed google searches, I set LANG="" as described here. This set the problem right. 
2. There were problems with the windows borders missing. I read on the net this was due to compiz not starting. I added compiz into "Startup Applications" and rebooted for this to work. 
3. Installing KDevelop was a pain as the package has been removed from the repository. I followed this.

This has been the list in 3 days after the update. I will update this list as I find new problems.

Ubuntu: Upgrade from 9.04 to 9.10

Overall the upgrade was okay. Was not entirely smooth, as 1-2 applications automatically got uninstalled and I had to install them again. Seems Canonical, the company behind Ubuntu, supports not everything I installed. In particular, openerp-server which was difficult to install in the first place, caused some issues with the upgrade and I have to uninstall it. Will install it again later.

Update : I dont know if it is just me or the new Ubuntu has better music drivers. I am using Rhythmbox, and I think the quality of music is better after the upgrade.

Its like falling in love with Ubuntu all over again.

Epiphany: The Fastest Browser on Ubuntu

I accidently landed upon Epiphany recently and I am loving its speed.

Ubuntu: Missing Skype from Panel?

I accidently made some change in my panel, and after that there was no way left to access skype after O minimized it. To correct this, I proceeded as per http://ubuntuforums.org/showthread.php?t=194980 . Just add "Notification Area" in your panel.

The same would work for dropbox and other application that might have recently disappeared from the panel. 

Rotating Wallpaper/Desktop Background in Ubuntu

Drapes is a cool tool to automatically periodically rotate ubuntu wallpaper. Just install it and then configure by System > Preferences > Desktop Drapes

Connecting to Wired Connection on Linux, Else to Wireless

This did not seem to work on my linux system. It would always first try to connect to wireless and when that failed, it would just sit there. I had to manual do ifdown and ifup on the wired interface. I asked about this question on the ubuntu mailing list, and they recommended wicd.

Wicd connects to a wired connection if there is any, else allows you to connect to a wireless. It works just fine, but does not connect to the wireless automatically (not sure though, probably only sometimes). But I what I needed works just fine with wicd and I am totally satisfied.

Upgrading to Jackalope

The new version 9.04 of Ubuntu is out. I followed http://www.shivaranjan.com/2009/05/01/ubuntu-linux-how-to-upgrade-to-ubuntu-904-jaunty-jackalope-from-ubuntu-810-intrepid-ibex/ to upgrade. Now this was some time back, and now I vaguely remember initially I had some sound problems. Other than that, it has been running just fine without any problems whatsoever.
