A critical security vulnerability in Adobe Flash player was discovered about twelve days ago and Adobe has released a new version which has the problem solved. However, there is no 64bit version of Flash with the security update available yet. Besides, Adobe temporarily removed the 64bit Flash download link so you cannot download it now. Since security is concerned, I had removed the 64bit one and installed the 32bit version with npviewer through the synaptic package manager as it is the new version with the security update. Although this 32 bit one is very unstable and crashes many times, I cannot take the risk of having security problem. Those who have installed the 32bit version then have been experiencing the problem that you cannot click any buttons on the Flash player, open the /usr/lib/nspluginwrapper/i386/linux/npviewer file and add the following line just before the last line.
So, please do not try the rest of this blog entry except for this one
I think there are numerous 64 bit Ubuntu users who are suffering from the crash of Flash Player just like myself. There is a better way to install Flash Player for 64 bit Linux than installing one from the Ubuntu repository and that is what I am about to write. This is obviously not the perfect solution yet I think the best way to use 64bit Flash Player for now. I hope Adobe will release a stable 64 bit Flash Player for Linux soon. Anyway, here we go!
In my case, the latest alpha version of 64 bit Flash player does not work well (e.g. Video on youtube constantly freezes) yet the previous alpha one works better. So first, try the latest one and if it doesn’t work well, download the following one.
*** This part is added on the 28th of September, 2009 *** I installed the latest alpha version which is libflashplayer-10.0.32.18.linux-x86_64.so.tar.gz today (the 28th of September, 2009). So far, it seems fine.
*** Updated on the 2nd of May, 2010 libflashplayer-10.0.45.2.linux-x86_64.so.tar.gz works fine.
*** Updated on the 4th of Feb, 2011
flashplayer10_2_p3_64bit_linux_111710.tar.gz works fine.
Before installing it, if there is a previously installed Flash player, it has to be removed first.
To check it, open ‘Synaptic Package Manager’.
System -> Administration -> Synaptic Package Manager
Search by 'flash' and make sure neither flashplugin-nonfree nor flashplugin-installer is installed. If any of these are installed, remove first.
-Search by ‘flash’ and make sure neither flashplugin-nonfree nor flashplugin-installer is installed. If any of these are installed, remove first.
Extract the libflashplayer file downloaded to the firefox ‘plugins’ directory.
e.g.) If the file is in the /home/username/Desktop directory,
$ cd /usr/lib/firefox/plugins
$ sudo tar -zxvf ~/Desktop/flashplayer10_2_p3_64bit_linux_111710.tar.gz
To use this Flash player in other browsers such as Opera, create the symbolic link to the /usr/lib/firefox/plugins/libflashplayer.so file in the ‘/usr/lib/mozilla/plugins’ directory.
$ cd /usr/lib/mozilla/plugins
$ sudo ln -s /usr/lib/firefox/plugins/libflashplayer.so
If the file with the same name already exists, user ‘f’ option to overwrite it.
Unfortunately I don’t really have time to explain the details nor am I sure if Ubuntu supports his/her graphics card so I’m putting here some information which can be a starting point to get what he/she wants.
To enable some basic visual effects, select the ‘Appearance’ menu.
-System -> Preferences -> Appearance
-Select the ‘Visual Effects’ tab -> Select the ‘Extra’ effect -> Click the ‘Close’ button.
If Ubuntu or Compiz doesn’t support your graphics card, you may get some error message here.
If you are using ATI or nVidia Graphics card, I strongly recommend you to install EnvyNG which automatically checks what Graphics card you use and finds the proper driver for it. It only works for ATI and nVidia ones. I am using Intel one so I cannot use it and therefore can’t explain how to use it. To install it, open the ‘Synaptic Package Manager’
System -> Administration -> Synaptic Package Manager
and search by envyng then you can see ‘envyng-core’, ‘envyng-gtk’ and ‘envyng-qt’. Install envyng-gtk (I assume you’re using Ubuntu but not Kubuntu) and it will install envyng-core and envyng-gtk.
OK, get back to the visual effect one. After selecting the ‘Extra’ visual effect, it should have some visual effects and now it’s time to customise it to have more effects. If you have not installed ‘CompizConfig Setting Manager’ yet, install it first.
-Run ‘Add/Remove Applications’ -> 1. Make sure it shows ‘All available applications’ -> 2. Search ‘compiz’ -> 3. Check ‘Advanced Desktop Effects Settings (ccsm) -> 4. Click the ‘Apply Changes’ button.
Run the ‘CompizConfig Setting Manager’
-System -> Preferences -> CompizConfig Setting Manager
Now you can have whatever you want with Compiz-Fusion!
e.g.) To have the Cube, enable the ‘Desktop Cube’ and ‘Rotate Cube’
This is Ubuntu Linux 9.04 just released about two days ago (24th, April) as I already mentioned in my previous post.
I used a LiveCD of Ubuntu Linux 9.04 to check if it works well on my PC. It fortunately works well so I upgraded mine from 8.10 to 9.04. The screencast above is made after the upgrade. It looks slow in the video yet that’s because of the software I used to record the desktop. It works really fast indeed without the software used to screencast.
These are screenshots taken before the upgrade.
Start Upgrading to 9.04
Upgrade In Progress
The size of the memory installed on my PC is 4 GiB but it does not have to be 4GiB or bigger. I need 4 GiB for the software I use to develop web applications. Those development tools and servers require lots of memory. However, based on my experience, without using that kind of heavy applications, 2 GiB is enough or even 1 GiB is still fine although for 1 GiB memory I rather recommend Xubuntu which is a type of Ubuntu with Xfce as its desktop environment. Xfce is lightweight and fast.
Compiz also seems to be a bit unstable yet hasn’t crashed. I’m sure the Ubuntu development team will make it stable soon. It normally becomes fairly stable one month after it is released. In the meantime, the users can report all the bugs they found through the issue tracking system for Ubuntu that is Launchpad.
So what I feel about the new release is that it seems to be more stable than the previous release (8.10). I’m quite satisfied so far. The following information is a quick review of the new one.
* The problems in the previous version (8.10) yet fixed in the new version.
-X-Window (probably only GNOME?) freezes if Ctrl+Alt+F1~F6 keys are pressed to enter console mode => Fixed in 9.04
-Firefox freezes with Google toolbar when opening more than one Firefox window. => Fixed in 9.04 (I’m not sure if it was fixed before but I had it when I used 8.04).
-The window decorator of some KDE applications using QT library (e.g. Umbrello, Kompare) disappears and it is impossible to resize the windows of these applications. As far as I remember, it only happens in 64bit version meaning 32bit version doesn’t have it. => Fixed in 9.04
Oh I forgot to say that Ubuntu 9.04 has Open Office 3.0 pre-installed by the way.
OK, these are what I found so far.
I’m using Compiz, GNOME Do, Cairo Dock and many other useful applications. One good news is that Cairo Dock which is my favourite Dock application can now be found from the Ubuntu repository which means all I need to do in order to install it is to use ‘Add/Remove Application’ menu. 😀 I had to add the Cairo Dock repository manually before if I want to install it or even worse scenario is downloading the deb package file and install it manually.
A new file system namely ext4 which is faster than ext3 is available in Ubuntu 9.04. However, for now it might not be a good idea to use it as there may be some problem like this. https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/317781?comments=all
It seems to be fixed though. Anyway, the comments in this bug report post are very interesting. 😀 This might be evidence of how Linux is being evolved by the developers as well as the users of it I believe.
