Ubuntu 10.04 LTS Lucid Lynx Review

On April 24 Ubuntu released its 10.04 release, I was currently using 9.10 (32 bit) and because 10.04 is an LTS and even because I wanted to switch from 32 bit to 64 and from ext3 to ext4 I've decided to do a fresh install on my HP DV3650.
The HP DV3650 has this spec:

• Intel Core 2 Duo P8600@2.4Ghz
• 4GB DDR2 Ram
• 320 Gb HD
• Nvidia 9300M with 256Mb dedicated Ram
• 13.3" LED Display
• Main Ports: 3 USB, 1 HDMI, Ethernet

I also use an external Philips 19" Monitor via HDMI to DVI connector.

Installation process
The graphic install it's almost identical to the on in Karmic Koala expect from the fact tath by default it doesn't show any option after the boot. If you want to change language or keyboard you need to push any key.
I think that in the mind of the developers this choice should give to the install procedure a much cleaner feeling but as I need an italian keyboard and prefer an English OS it doesn't feel good for me (and probably for anyone who prefers an English OS but lives outside the USA).
By the way if you don't change the keyboard before installing Lucid you can select it during the graphical install.

First Boot
Even the boot time feels about the same as Karmic (maybe Lucid Lynx is slightly faster).
I didn't elapse it because I think the correct unit for measuring the total boot time its the human feeling and not seconds. Why should I care if the total boot time its 15 or 16 seconds?
I don't know if it feels faster because of minor improvements, the switch to 64 bit or to ext4 or only for the exicetment of trying the new Ubuntu.
The only things that counts is that it is fast.
The boot up speed it's comparable to the one of my personal MacBook Pro (se previous posts) and much faster of a tipical Windows XP or Vista (at present I didn't try Windows 7 for real work).

User Experience
The user experience it's wonderful. The system feels really responsive wich is much more important that the boot time.
The new dark theme without all that brown it's a lot better even if the icons still are to orange for my taste. As a mac user I did appreciate that they put the window buttons on the left style instead of the right like Windows. Obvously if you don't like this choice you can always change theme.
One thing to note it that when I tried Karmic Koala on day 0 I've had a lot of crashes (where a lot means for me a crash every 2/3 days) for the first moth. I think that the main problem where the nvidia drivers as the crashed significantly decreased when I switched to the nvidia official launchpad repository.
Lucid instead it's been rock solid from the first day even if  (as usual) a lot of updates appeared on the official repositories especially in the first week (after only five days a new kernel was also available).

I'm having a  little experience issue with Nautilus. In the previous version I could configure it to show the location in the address bar instead the bread crumbs path. I didn't find how to do it in this release...
I can edit it with +L but I can't keep the address visible; Nautilus will switch to the bread crumbs by default.

Hardware and Drivers
First I have to say that Ubuntu recognized and configured correctly almost all my hardware. The only thing that still isn't working correctly is the volume slide on the laptop. It did't work well on Karmic and it still doesn't work well on Lucid. Not a big problem for me as I prefer to use shotcut keys anyway.
Before Lucid was released I've heard a lot of the new nvidia nouveau drivers which are the default on Lucid.
They work; they recognized and configured both the 13.3" monitor of the laptop and the 19" external monitor. You can correctly use the laptop monitor and the external one together or just one at a time.
On the other side the nouveau drivers don't support 3D acceleration and they don't let you run all the effects of Compiz too.
The most notable thing is that they are a lot slower than the nvidia closed source conunterpart. If you are a purist (or a fanatic) you can stay with the nouveau but I warmly suggest you to use the closed ones. The system will be faster and more responsive which is more important than an open vs source flame for me.
I strongly believe in open source but I feel that the difference of the two drivers is too evident not to be pragmatic choosing the more convenient way to work.

Obviously even using the closed source drivers I can use both my monitor without problems.
Developing software I prefer to use only the 19" external monitor and switch the desktops instead of turning my head left and right trying to find wath I'm looking for but maybe the double monitor solution could be userful to you.

Software
Speaking of software I've installed some extra repositories (mainly medibuntu) so I could have all the closed source codecs and google-earth (which I love).
I've installed both google-chrome and chromium (the non branded version of chrome) and they work beautifully. By the way: they are a lot faster than firefox!
I've also downloaded virtualbox from www.virtualbox.org. I didn't install the ose version (available from repository) because with that version I could not connect USB devices to the virtual machine. I've downloaded the 3.1.6 64 bit release for Karmic as the Lucid version wasn't available till a few days ago. Now you can find the 3.1.8 specifically packaged for Lucid or you can add the virtualbox repository to your synaptic manager.
Skype has been removed from the medibuntu repo so I've downloaded it directly from skype website. It works perfectly and I can use the integrated 1.3mpx webcam installed on my laptop without problems even if the version was designed for ubuntu 8.10.
Flash
I've also installed flash plugin. First I've tried the plugin available from the repository but on youtube sometimes I could not click on the player buttons (if you do a search on google you can find other people having the same problem).
looking in the filesystem I found out that the repository installed the flash 10.1 32 bit version and firefox was using this plugin through the 32 to 64 bit wrapper.
The solution for me was to download the 64 bit native plugin directly from adobe. Uninstall the plugin from the repository and update the symbolic links.
Here are detailed all the (simple) operations needed and you can even find a script which does all the work for you.

The end
In this short review I've used Karmic (9.10) as a meter to evaluate how good Lucid Lynx is. I should say that I'm an Ubuntu user from the beginning and its almost 3 years now that I'm using it intensively. I've tried Ubuntu on a lot of notebooks and even on some "servers" (actually desktops used as servers) and virtual machines. After all
I've to say that after a series of release in descendant quality this it the best release Ubuntu ever had!
Rock solid, fast, an almost perfect hardware detection and a lot of software all up to date immediately available. I don't know what else I should ask for.

Ubuntu 8.04 Hardy Heron on Asus Z53Jr

On April the 24th the final version of Ubuntu 8.04 "Hardy Heron" was released.
In this post I'll evaluate how well it fits on my Asus Z53Jr Laptop.

My notebook (which is now a years old but still amazingly fast) specs are:

• Intel Core2duo T7200 2GHz 4Mb cache
• 2Gb RAM DDR2
• 160Gb HD
• 15" 1280x800 TFT screen
  
• ATI X2300 Video Card with 128Mb RAM up to 898Mb shared memory
• SD Card Reader
• 1.3 MPx Camera
• Network: Ethernet + Intel i3945 802.11 a/b/g Wireless
• Ports: 4 USB 2.0, 1 FireWire, VGA out DVI out
  

One year ago I've installed Ubuntu 7.04 wich I've later upgraded to 7.10.
This time I wanted to see all the improvements of a "fresh" distro so I backup-ed all my data and I went for a fresh install.

I've downloaded the standard cd, burnt it and rebooted the system. The I selected my keyboard ad proceeded with the live distro so I could access the graphic installer from it.
The live cd worked fine recognizing the correct screen resolution (1280x800) and the intel wireless also.

I clicked on the install and a wonderful installation process reduced to 7 easy steps let me tell Ubuntu all It needs for the installation BEFORE it started leaving me free to play with my baby or watch tv while the installation procedure took care of everything!

At the end of the process the only thing I've had to do was to reboot my system which was perfectly usable (see previous post for the problems on 7.04 if interesed).

The wireless card was recognized without any problems, and the only thing I've had to do was to insert my WPA key to enable the network.
I don't have an ethernet plug near my notebook so wifi is the only chance to have an internet access for me.

The repositories (just a suggestion)

Having my internet access out of the book before trying everything else I've enabled all the official repositories and added the medibuntu repositories. If you want to add this repository too please refer to the howto on medibuntu's website.
In medibuntu you can find acrobat reader, google-earth, skype all packaged and ready to be downloaded.

ATI Card (Restricted Modules)
The default driver used by Ubuntu is the free ati one. If you want the ati proprietary driver (fglrx), and I suggest this if you want applications like google-earth to work open a prompt and type in

sudo apt-get install xorg-driver-fglrx

after this select the restricted driver from System -> Administation -> Hardware Drivers and reboot.

Composite and OpenGL Support

The fglrx driver developed by amd-ati is now at a decent level of development which means that you can use composite without problems.
You can even use openGL without any major problems.
The point is: you can use them individually but not together!
If you try to do so (try to open google-earth with composite enable) the 3D rendering will flicker resulting in an unasable application.
This is not Ubuntu's fault but a problem related with the fglrx driver itself.
The truth is that I don't really care much of all the fancy composite stuff so this is not a big problem to me.

Suspend & Hibernate
In ubuntu 8.04 they work PERFECTLY out of the box! This is fantastic considering that we are talking about a notebook. Really a great improvement compared to the previous versions of Ubuntu.

Function Keys and Extra Keys
The notebook has 5 keys near the power button. None of them is working. They work in Vista, which came preinstalled on the notebook, using a special application made by Asus running in background.
If you know hot to make them work fell free to contact me.
There is another series of special keys (Fn keys):

• Fn+F1 (suspend) works
  
• Fn+F2 (enable disable wireless) not working
• Fn+F3 (opens the mail client, or anything you prefer) works
• Fn+F4 (opens the browser) not working
• Fn+F5-F6 (display brightness up/down) working
• Fn+F7 (toggles the display lamp on/off) woks
• Fn+F8 (external display) not tried yet
• Fn+F9 (enables/disables touchpad) not working
• Fn+F10-F11-F12 (audio on/off, down, up) working

1.3 Mpixel Camera & Microphone
The 1.3 Mpixel camera & the integrated microphone are working perfectly out of the box. I've tested them using skype 2.x. & the sound recorder tool.
The only thing I've had to do was to enable Capture in the sound volume panel and try out some setting of Front Mic & Front Mic Boost to adjust the recording level.

Firefox 3 (beta 5)???
The only thing in which I have some doubts at the moment is the presence (by default) of firefox 3 beta 5 and not the old (but stable) firefox 2.
From this beta you can see that the new firefox will be an absolutely good browser but at present there are some little things that do not convince me:

1. the "page loading" rolling icon on the tab never stops even when the page is fully loaded
   
2. google browser sync plug-in at present isn't compatible with the new firefox... is you are used to google browser sync as I am this is really annoying.

I'll try it out for for another week but I'll probably switch back to firefox 2 (which is donwloadable from the official repositories of course).

Final Thoughts
In my opinion Ubuntu 8.04 it's a great improvement compared to 7.04 (and 7.10 of course).
This distro resolves a lot of problems present in previous releases.

1. No need for the alternate cd anymore. You can do the live install procedure without problems.
2. Improvement in hardware management: wireless card, web camera, function keys
   
3. Better fglrx driver "out of the box" (after enabling the restricted modules of course)
4. Great suspend and hibernate (a must for a notebook)

I think that if you have a notebook you should give it a try... expecially with hardware similar to mine.

As usual feel free to contact me if you have any doubts. I'm not a linux geek of fanatic but a java programmer but if I can give you some help you're welcome.

ATI Catalist 7.12 on Ubuntu 7.10

Recently I've tried this drivers and compiz started working on my Mobility Radeon X2300.
Here's how I've got the drivers to work.
1 remove old drivers
first you need to remove the drivers downloaded from the ubuntu repository.

$ sudo apt-get remove xorg-driver-fglrx

2 Install the new driver
follow the procedure as described on point 2 at http://wiki.cchtml.com/index.php/Ubuntu_Gutsy_Installation_Guide

3 bugs
With this lease you can enable compiz but video playback, google-earth and all the applications which require an overlay start flickering and are unusable.
The system works perfectly with compiz disables :(

4 power management
With this release ati (amd) claims that the problems related to suspend and hibernate are solved.
I haven't tried it yet as I've managed to disable this features time ago (when the system tried to suspend hanged-up) and I don't want to retry right know to figure out if now is working (maybe on a fresh install of 8.04). If you think you can have an easy configuration guide (packages needed, and manual editing to /etc/... files feel free to contact me. If it works on my Asus notebook I'll add it on my blog.

Ubuntu 7.10 gusty gibbon on Asus Z53Jr F3Jr

I've upgraded my notebook from Feisty to Gusty. So this isn't a "fresh install experience". I've published the Asus Z53Jr specs before but here they are (again)

Notebook Specs

• Model: Asus Z53Jr / F3Jr
  
• core2duo T7200 2GHz 4Mb cache
• 2Gb RAM DDR2
• 160Gb HD
• ATI X2300 Video Card with 128Mb RAM up to 898Mb shared mem
• SD Card Reader
• 1.3 MPx Camera
• Ethernet + Intel i3945 802.11 a/b/g Wireless
• Ports 4 USB 2.0, 1 FireWire, VGA out DVI out

Upgrade Procedure
When I logged in Feisty and opened the update manager feisty suggested the distribution upgrade, and so I did.
The all process was smooth and clean and took less than 2 hours (most of which were spent downloading the software from the internet).
The upgrade procedure told me that support for some software ended... not a real problem for me (I've never used gcj, I usually download the official jdk directly from sun).
Here are some screenshots:


Fisrt Look
The first impression is that Ubuntu improved it's general usability.
I usually work connected to my network via WPA wireless. Using the restcricted modules as in feisty I managed to use the intel wireless card and ati x2300 gpu without any problems (except for the suspend issue, see below).
The drivers where already installed before in feisty, gusty simply upgraded them to a newer version.
Two major usability improvements on the network configuration are that without any manual configuration now you can automatically activate the wireless connection without unlocking the keyring when you login. This could have been done in feisty with some configuration now there is a checkbox directly on the unlock keyring dialog.
Another improvement is the support of wpa connectivity when you manual configure your network: now if you want to manage your network manually you can do it really easily!

Almost everything it's working without problems
As in Feisty this things are working without any issues

• display driver at correct resolution (1280x800)
• touchpad
• usb ports
• integrated sd card reader
• Fn buttons
• Fn+F1 (suspend) is recognized but I thing that the ati driver has major issues while suspending the notebook
• Fn+F2 (enable/disable wireless)
• Fn+F4 opens the browser
• Fn+F5,F6,F7 panel light controls
• Fn+F10,F11,F2 sound controls
• Fn+Arrows the sound controls (tested in Banshee)

Not Tested
I've not tested the external display and the Fn+F8 button as I don't have an external display available right now.

The Bad Part: Things that don't work
Suspend and Hibernate
Suspend and Hibernate still doesn't work :(!!
I suspect an issue with the ati fglrx driver. I've tested the 8.42.3 driver downloaded directly from ati without any success too.
The only thing I've managed to do on my system was to stop the system from suspending and hibernating installing this packages on the system:

• apmd
• hibernate
• uswsusp

Composite
Composite is disable and doesn't work with the fglrx driver. With the new 8.42.3 driver it is theoretically supported via AIXGL but the only thing I've got was a white screen (an internet search told me that I'm not the only one).

1.3mpx camera
The integrated 1.3mpx webcam isn't recognized as in feisty. In the next days just for curiosity I'll try to recompile the syntek driver http://syntekdriver.sourceforge.net/ (se previous posts).

If you find any workaround for this problems (suspend and hibernate in particular) or if they are working for you on the same notebook (or very similar one) via a fresh install please feel free to contact me.

Ubuntu Gusty Gibbon

Last night I've installed Ubuntu 7.10 aka Gusty Gibbonon my Asus notebook (please see previous posts for the details on the notebook). Actually it wasn't a fresh install but an upgrade from Feisty (7.04).
The upgrade process proceeded without any problem (maybe the servers where a bit slow but this is normal on day 0) and Gusty seems to work without any problems. This week end I'll try it a bit more in depth if Michele (again see previous posts) will leave me enough time to experiment the new distro.

Cheers to the ubuntu team,
Terenzio

Due to the ATI Card issue with Xorg you should intall feisty in textual mode via atlernate CD or DVD.
The system will install without problems. When prompted for the video resolution remember to select 1280x800!
On the first reboot you won't be able to login graphic mode. Login in text mode with your notebook connected to internet via ethernet card and type (look here for a more detailed explanation):

sudo apt-get update
sudo apt-get install linux-restricted-modules-$(uname -r)
sudo apt-get install xorg-driver-fglrx
sudo depmod -a

and yes, before you ask it: I'm using the restricted modules.
next configure the video card:

sudo aticonfig --initial
sudo aticonfig --overlay-type=Xv

and reboot

sudo shutdown -r now

at the reboot the system will login via gdm. Now lets take a look to what is working and what not.

Working

• video card at correct resolution
• sound (even Fn + F10, F11, F12 keys )
  
• sd adapter
• usb & firewire ports
• display lamp (even Fn + F5, F6, F7 on/off)
• other shortcuts Fn + F1, F2 are recognized)
• the shotcut keys on the top left of the notebook works
• the microphone (* see note)
• hibernation
  

*I've tested the microphone mainly using skype 1.3.0.53 and sometimes worked sometimes not. When it did not work I simply restarted skype and this resolved any issue.

NOT Working

• the on off pad switch Fn + F9
• the sleep mode Fn + F1 (the system doesn't wake up correctly, if you can help feel free to contact me)
• the 1.3MPx camera
  

Another thing that doesn't work out of the box is the cpu frequency scaling but this issue it's easy to fix:
Edit the /etc/modules file (sudo gedit /etc/modules) and add this line:

acpi-cpufreq

Next: I like to manage the cpu speed via the cpu frequency monitor applet and if you want to do the same you should set the sticky bit to the /usr/bin/cpufreq-selector executable.

sudo chmod +s /usr/bin/cpufreq-selector

You will need two applets (one per core) as the F3Jr is a Core2Duo processor.
That's all for now. If you have any questions please feel free to contact me.
bye
