A weeks a go, I just bought a new notebook for myself, Lenovo Thinkpad R400 RZ7 which comes with pre-installed Windows Vista (free upgrade to Windows 7 ’til 31 Jan 2010), powered by Intel Core 2 Duo P7370 (2.0GHz, FSB 1066, Cache 3MB), Chipset Intel 45GM, 2GB DDR3 RAM, Intel Graphics 4500MHD, 14.1-inch WXGA TFT […]

A weeks a go, I just bought a new notebook for myself, Lenovo Thinkpad R400 RZ7 which comes with pre-installed Windows Vista (free upgrade to Windows 7 ’til 31 Jan 2010), powered by Intel Core 2 Duo P7370 (2.0GHz, FSB 1066, Cache 3MB), Chipset Intel 45GM, 2GB DDR3 RAM, Intel Graphics 4500MHD, 14.1-inch WXGA TFT with 1280 x 800 resolution, 250GB hard drive, DVDRW, integrated camera 2.0MP, VGA out (no HDMI), WiFi, Bluetooh, card reader, LAN and modem.

By default, Ubuntu disable X window reset feature by keyboard shortcut in Jaunty (9.04) and Karmic (9.10). However we can still enable this feature, here is how:
1. Go to System > Preferences > Keyboard

2. Choose Layout Options

3. Choose  Key Sequence to Kill X Server, make sure it’s checked.

After success upgrading to Karmic on my PC, now it’s turn to upgrade my wife’s netbook which is HP Mininote 1016.

After success upgrading to Karmic on my PC, now it’s turn to upgrade my wife’s netbook which is HP Mininote 1016. Before upgrading, this netbook using Ubuntu 8.10 Intrepid Ibex as it’s OS, and everything work out of the box. However after upgrading to Karmic, I found problems related to Broadcom Wireless driver, it doesn’t working! Then I search on Google and found the solutions, here is how:

Offline Mode [in case you can’t connect using wired connection]:

• Open Synaptic Pacakage Manager
• Make sure 9.10 LiveCd is in CD drive
• Go to Settings > Repositories > Ubuntu Software
• Check the installable from cd and close
• Reload
• Search for “bcmwl-kernel-source”
• Mark for installation
• Apply
• Reboot computer

Online Mode [You can connect to internet whether using wired or other wireless device]:

• Open Synaptic Package Manager
• Search for  “bcmwl-kernel-source”
• Mark for installation
• Apply
• Reboot your computer

I’m using the second option [Online Mode] because I’m able to connect to the internet using my SMC USB Wireless Card.

Just upgrading to Ubuntu 9.10 Karmic Koala this morning, overall I’m quite happy with it’s performance, it’s faster than previous version (Jaunty, etc).

Just upgrading to Ubuntu 9.10 Karmic Koala this morning, overall I’m quite happy with it’s performance, it’s faster than previous version (Jaunty, etc). However I’m still facing some minor problem that is not solved correctly until this Karmic release, that is when I play video on Totem or VLC, after several minutes the video becomes freeze and this happen every several seconds / minutes.

So I decided to find the solution on the Ubuntu forums and found the solution:

STEPS: Compiz Configuration

1. Download CompizConfig Settings Manager from Ubuntu repository.
2. Navigate to.. System –> Prefences –> CompizConfig Settings Manager
3. Navigate to.. General –> General Options
4. Click “General Options” to open window
5. Click “Display Settings” tab
6. Uncheck “Detect Refresh Rate”
7. Move “Refresh Rate” slider to 60, or set 60 in the box
8. Check “Sync to VBlank”
9. Click back button to move back to main CompizConfig window
10. Navigate to.. Utility –> Video Playback
11. Uncheck “Video Playback” then exit the CompizConfig Settings Manager.

STEPS: Nvidia Configuration

1. Pull up nvidia-settings
.. Navigate to.. Applications –> System Tools –> nvidia-settings
.. or open a terminal, type “nvidia-settings” , press enter
2. Click “X Server XVideo Settings”
3. Check “Sync to VBlank” _IF_ not checked
4. Click “OpenGL Settings”
5. Uncheck “Sync to VBlank” _IF_ checked
6. click quit button
7. click quit button
8. Reopen nvidia-settings to verify that config changes were saved.
.. IF they were saved, you are done with step 8.
.. IF they were not saved, ~/.nvidia-settings-rc in your home directory
.. may be under root permissions. You will need to chown chgrp for the file.
.. Then you will need to start back at Step 1 and repeat all steps.

IMPORTANT: Reboot your machine when finished. The driver changes won’t function correctly until you reboot

This is the screenshot of my nvidia settings after fixed:

That’s it, now I can enjoy watching my movie collections without freezing…

Today, I’m invited by Google Adsense team to join Adsense Webinar. Last time I’m tried to attend webex webinar using Linux, I haven’t succeeded (several years ago using other distro). Thanks god, now I can join webex webinar using Ubuntu 8.04 Hardy Heron + Firefox. What I’m to do to fix this is:

Step 1: Type this command on your terminal:

sudo apt-get install libstdc++5 sun-java6-plugin

Step 2: Edit your ~/.profile and add these two lines:

export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.66
export PATH=$JAVA_HOME/bin:$PATH

Step 3: Restart X session by logging off/on or ctrl+alt+backspace
