I experienced a lot of random X server crashes using the proprietary driver for the NVIDIA graphic card on my Thinkpad T61 running Ubuntu 9.04 x86 with Compiz activated.
I managed to fix the problem by installing the lastest NVIDIA driver. I wrote a little script to automate the process and save time. I recommend you to run this in command line mode. Here it is:

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:
|
1 |
sudo joe /etc/usplash.conf |
I should contain these lines:
|
1 2 |
xres=1680 yres=1050 |
The next step was to update the “initial RAM disk”, that is used when the system boots up:
|
1 |
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:
|
1 |
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=7281a5b5-6dd5-4011-beff-27339b4b9693 ro splash vga=872 |
Nice and clean!

I use the following script to automatically update my Ubuntu box.
I don’t recommend using this on your production servers!
