Kernel boot parameter

There are some problems running this laptop with a modern linux kernel.

The trackpoint does erratic mouse movements out of the sudden
- Solution: add i8042.nomux=1 as kernel parameter
Heavy using of the usb or graphics bus (3D rendering) leaves this pci subsystems unusable (kernel-oops)
- Solution: add irqpoll as kernel parameter
Direct rendering is broken, if you use usplash.
- Uninstall usplash
The bios is buggy.
- Recompile a new File:DSDT.zip and put it into

/etc/initramfs-tools/DSDT.aml

This leads into the following /boot/grub/menu.lst addition

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
##      kopt_2_6_8=root=/dev/hdc1 ro
##      kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=YOUR_UID ro irqpoll i8042.nomux=1

GLX and DRI works, but it is a little buggy and not very performant. So don't use (!) compiz - it's no fun.

Troubleshooting

I had some real trouble getting X11 with direct rendering to work after a system upgrade occured. X11 hung and the whole system froze.

Then booted in safe mode and use the following option in your xorg.conf

Section "Device"
     Option         "noaccel"   "true"

for starting the xserver. Change it back, when X was up and restart X.

Heres what I did:

1. I removed usplash and run update-initramfs for ALL (!) kernel flavours on the machine.

apt-get remove usplash usplash-theme-ubuntu
update-initramfs -c -k all

2. I removed the xserver-xorg-video-intel driver package. It hinders the xserver to start and reinstall xorg-video-i810.

apt-get remove xserver-xorg-video-intel
apt-get install --reinstall xserver-xorg-video-i810

3. I rebooted the machine

Now the Xserver worked with direct rendering.
