Recently I started to have some problems viewing flash videos, specially youtube videos. Sometimes they worked, sometimes they didn’t. Sometimes just the buttons in the video/flash movie didn’t work. Looks like the problem is related to some update in karmic.
The solution for this problem is to install flash-player alpha 10 (amd64) from Adobe.
There is a nice post at ubuntuforums with the steps you need to do in order to solve this issue.

Yet, another fix for Ubuntu Jaunty. I have a Sony Vaio FW with a ATI Mobility Radeon HD 3400 Series and compiz works with the fglrx driver.. but it doesn’t work very well. It lags when minimizing/maximizing windows and it also lags on a window resize. The Solution?
Ubuntu-X Swat team PPA! They have a PPA called XServer with no backfill functionality. This is all you need! Added the repositories to /etc/apt/sources.list update, upgrade and your’re done!

I’m posting using the recent version of firefox, 3.5! It’s a RC but it works well, very well! I was really impressed with the overall performance. So, for those who want to use firefox 3.5 on ubuntu (jaunty) you just have to do the following steps:

1. Add the following repositories to /etc/apt/sources.list
   deb http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/ubuntu-mozilla-daily/ppa/ubuntu jaunty main
2. sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 247510BE
3. sudo apt-get update && sudo apt-get install firefox-3.5
4. Firefox 3.5 is installed but we still have 3.0 (I maintained it in the system) and so we have to change the default symlink by opening a terminal and doing:
   cd /usr/bin
rm firefox
sudo ln -s firefox-3.5 firefox

There is a minor bug for those of you who use ATI proprietary driver, fglrx, a render problem with pngs. They render with the wrong colors. You have to change a setting on firefox. On the config page, about:config, change the setting gfx.color_management.mode from 2 to 0.

I have a Sony Vaio FW11M. It’s a really great laptop! The only thing that doesn’t work well by default on Ubuntu is the brightness control.
There are some little tricks and the kernel needs to be patched. Egaistek is a life saver! He made available a patch and the instructions to solve this problem on the both versions of Ubuntu 8.10 (32 and 64 bits) at his site. Keep up the good work egaistek!

Yesterday the new Ubuntu was released. Its know as Ubuntu Jaunty Jackalope.

I had the opportunity to test it yesterday. It looks greate and has some goode new features that I really apreciate but what impressed me allot was the boot time. It just flys to GDM.

Sadly it has some glitches with my Sony Vaio FW. Compiz goes slow with my ATI Mobility Radeon HD 3470 and by default the brightness control does not work (needs a kernel patch).

I also had the sensation that the hole system was a little slow, slower than on 8.10.

So for me it’s back to 8.10.
