Finished the install just 30 minutes back from the time I started writing this. By the way, the following ain’t gonna be a review, just some stuff I did after installing and the problems I had. If you want a review <a href="http://lmgtfy.com/?q=ubuntu+12.10+review" target="_blank">let me google that for you</a>.</p> <p>Ubuntu no longer fits in a CD. It’s got bigger (that’s what she said). <a href="http://www.ubuntu.com/download/desktop" target="_blank">The ISO</a> is 800 MB now, so if you’re not installing online, you need to create a DVD or a USB.</p> <p style="text-align:center"><img alt="" class="aligncenter" decoding="async" fetchpriority="high" height="268" src="https://blog.thameera.com/wp-content/uploads/2012/10/ubuntu_12_10_quantal_quetzal_dvd.jpg" title="ubuntu_12_10_quantal_quetzal_dvd" width="269"/></p> <p>I had previously fucked up the whole 12.04 install by messing up with xorg.conf, compiz and even wine, so formatted /home as well. A fresh install, literally. It went without a hitch.</p> <p>Was expecting everything to work smoothly after the install, but some did not. Nvidia drivers do not come by default (which is normal) but they did not appear under Additional Drivers as well. I tried <em>sudo apt-get install nvidia-current</em> and restarted, but the screens were messed up. Unity launcher was hidden and the screen resolution was fixed. A bit of googling showed that this was <a href="https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-updates/+bug/1068341" target="_blank">a known bug</a> in the kernel. The following workaround solved the problem:</p> <blockquote><p>sudo apt-get install linux-headers-3.5.0-17-generic<br/> sudo apt-get remove nvidia*<br/> sudo apt-get install nvidia-current</p></blockquote> <p>The dual monitor setup got detected and the display was set to TwinView automatically, so had no need to do them manually as I’ve <a href="http://noisythameera.wordpress.com/tag/dual-monitor/" target="_blank">mentioned previously</a> in the other blog. Anyway when you move the mouse from one monitor to another, there’s this deceleration which is a headache. This could be disabled by going to Displays and turning off Sticky Edges.</p> <figure aria-describedby="caption-attachment-926" class="wp-caption aligncenter" id="attachment_926" style="width: 655px"><a href="https://blog.thameera.com/wp-content/uploads/2012/10/desktop.png"><img alt="" class="wp-image-926" decoding="async" height="198" src="https://blog.thameera.com/wp-content/uploads/2012/10/desktop.png" title="desktop" width="655"/></a><figcaption class="wp-caption-text" id="caption-attachment-926">I keep the Unity launcher on both desktops coz it’s more convenient that way</figcaption></figure> <p>Installed ubuntu-restricted-extras next. Nothing special there.</p> <p>Then I downloaded the <a href="https://www.google.com/intl/en/chrome/browser/" target="_blank">Google Chrome deb</a> and tried to install, but this gave ‘The package is of bad quality’ error. As it turns out, this is also a known bug and continuing with ‘Ignore and install’ is the way to go.</p> <p><a href="https://blog.thameera.com/wp-content/uploads/2012/10/chrome-bad-quality.png"><img alt="" class="aligncenter size-medium wp-image-924" decoding="async" height="105" src="https://blog.thameera.com/wp-content/uploads/2012/10/chrome-bad-quality.png" title="chrome bad quality ubuntu 12.10" width="300"/></a></p> <p>The next step was to completely remove Ubuntu One. Coz that’s how we roll. The command is:</p> <blockquote><p>sudo apt-get purge ubuntuone*</p></blockquote> <p>In Quental, there’s this new Online Accounts section, in which you can log into most services like Twitter, Google and Facebook. After logging in I noticed that the Messaging icon was missing from the top panel. This could be turned on by going to Broadcast Preferences and checking <em>Start service at login</em>.</p> <p>Some of the things I’m gonna do next are <a href="http://www.omgubuntu.co.uk/2012/09/how-to-make-the-messaging-menu-icon-blink-in-ubuntu" target="_blank">installing the blinking messaging menu icon</a> and installing some cool stuff like Everpad, fogger, pinta, clementine, rubygems, ttytter and apvlv. And ccsm of course (just noticed it’s missing). Then enable wobbly windows. And then edit /etc/fstab to my liking perhaps. I may post some tips on new features, workarounds, etc in <a href="http://noisythameera.wordpress.com/" target="_blank">Accidents Happen</a>.</p> <p>Since it’s been less than hour, it’s too soon to tell how good Quental is compared with Precise (12.04).

However it’s a no-no for running in a VBox. Switched to gnome classic sans effects which improved the performance drastically.</p> <p>I had used LXDE for a few months <a href="http://thameera.wordpress.com/2011/06/01/moving-to-lubuntu/" target="_blank">about an year back</a> in my netbook. So I thought, why not give it a go again? Without removing the existing gnome packages, I typed,</p> <blockquote><p>sudo apt-get install lxde-core</p></blockquote> <p>into the terminal. It gave me the LXDE desktop, but that’s as far as it went. Just the desktop. No Leafpad, no PCMan, no LXTerminal, nothing. Hey, that isn’t LXDE! What’s LXDE without Leafpad or PCMan? So I went ahead and typed,</p> <blockquote><p>sudo apt-get install lxde</p></blockquote> <p>and, voila, here I have what I wanted. (Lesson: don’t install <em>lxde-core</em>, just use <em>lxde</em> and it gives you everything)</p> <figure aria-describedby="caption-attachment-872" class="wp-caption aligncenter" id="attachment_872" style="width: 300px"><a href="https://blog.thameera.com/wp-content/uploads/2012/07/lxde.png"><img alt="LXDE desktop on Ubuntu" class="size-medium wp-image-872" decoding="async" height="168" loading="lazy" src="https://blog.thameera.com/wp-content/uploads/2012/07/lxde.png" title="lxde ubuntu" width="300"/></a><figcaption class="wp-caption-text" id="caption-attachment-872">From left to right, Leafpad, PCMan file browser and LXTerminal (click to enlarge)</figcaption></figure> <p>Okay, the interface isn’t as polished as that of gnome, that’s a given. It’s only supposed to be lighter and faster. But unfortunately it felt like the system isn’t much comfortable having LXDE around. It felt like the kernel’s carrying a bulk. Not as smooth as the classic gnome experience. I know this isn’t the way it’s supposed to happen, so I’d try this for two or three days and switch back to gnome. Good thing I didn’t remove the gnome packages before installing.</p> <p>Oh wait, perhaps it’s a good time to try out XFCE!</p> https://blog.thameera.com/lxde-on-ubuntu/feed/ 6 871 https://blog.thameera.com/unity-2d/ https://blog.thameera.com/unity-2d/#comments thameera Thu, 16 Jun 2011 14:30:54 +0000 Uncategorized linux ubuntu unity http://thameera.wordpress.com/?p=407 It was a bumpy ride.

LXDE is light-weight indeed, but I had trouble running several applications with it. For example I couldn’t get gPodder to work no matter how hard I tried, and ibus was buggy.</p> <p>I was going to test run Gnome 3 but <a href="http://twitter.com/kau_mad">@kau_mad</a> said otherwise, so gave up. Which left me with two options: Unity and Gnome 2.</p> <p>Unity was originally intended for netbooks. (This was the default environment in Ubuntu Netbook Remix, remember?) Stuff like global menu bars were made with small screens in mind. Unity works, but I found it a bit too sluggish. The solution? Unity-2D.</p> <p>Unity-2D is a clone of Unity intended for low power computers like netbooks. While Unity has been written with GTK, Unity-2D uses the QT toolkit. It doesn’t require GPU acceleration , something which netbooks and other low-end machines can’t provide.</p> <p>To install Unity-2D in Ubuntu 11.04, all you have to do is to install the package “<em>unity-2d-default-settings</em>” from the Software Center. Log out and choose Unity-2D as the desktop environment. The interface is quite similar to Unity, but it may not be as slick as Unity is. For example you won’t get those lovely fading effects. However it’s able to provide you with the maximum possible Unity experience. <!--EndFragment--></p> <p> </p> https://blog.thameera.com/unity-2d/feed/ 15 407 https://blog.thameera.com/the-kewl-desktop-environment-kde/ https://blog.thameera.com/the-kewl-desktop-environment-kde/#respond thameera Sat, 11 Jun 2011 15:25:51 +0000 Uncategorized gnome kde linux lxde ubuntu http://thameera.wordpress.com/?p=402 So I wanted to get some first hand experience on KDE.
