Custom usplash resolution in Ubuntu

Recently I made a clean install of Ubuntu 9.04 on my Thinkpad T61.
I configured the figerprint, the accelerometer is reporting correct values.
I did not like the default resolution at boot. So I created a custom usplash.conf file:

sudo joe /etc/usplash.conf

I should contain these lines:

xres=1680
yres=1050

The next step was to update the “initial RAM disk”, that is used when the system boots up:

sudo update-initramfs -u

Next, I modified my /boot/grub/menu.lst file.
I added as a parameter for the current kernel the value vga=872:

kernel		/boot/vmlinuz-2.6.28-11-generic root=UUID=7281a5b5-6dd5-4011-beff-27339b4b9693 ro splash vga=872

Nice and clean!

No virtualbox kernel driver after kernel upgrade

After kernel upgrade, your VirtualBox modules will not be updated.
As a result, your virtual machines will not work.
Here is a quick fix. Run this in your terminal:

sudo /etc/init.d/vboxdrv setup

My experience with Ubuntu 8.04 Hardy Heron Beta

After a few tests with the new beta from Ubuntu, I decided to write some of my thoughts about this release.
Please note that this is a BETA release, has many unresolved bugs and needs to be polished before the final release.
Overall, everything seems better. A new host-based firewall application, the new Vinagre VNC client, Firefox 3 Beta 4 replaces Firefox 2 as the default browser, PulseAudio is now enabled by default, PolicyKit is now integrated in the administrative user interfaces, linux kernel 2.6.24, Xorg 7.3, GNOME 2.22, a few new compiz plugins.
In my opinion, there is a downside in this release regarding the PulseAudio sound server. Some non-GNOME applications still need to be changed to output to pulse/esd by default and the volume control tools are not yet integrated. Users with Audigy1 sound cards will be suprised to find out that the 5.1 output is not so good as it was in ALSA. It will be very difficult for a beginner to configure by hand the audio for best results in sound quality.
Anyway, many of this bugs will be resolved until the final release. Can’t wait!
