Kernel boot parameter

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

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

## ## Start Default Options ##
## default kernel options
# [...]
# kopt=root=UUID=YOUR_UID ro irqpoll i8042.nomux=1

Trackpoint

The trackpoint does erratic mouse movements out of the sudden

  • Solution: add i8042.nomux=1 as kernel parameter

Kernel-oops IRQ 11

Heavy using of the usb or graphics bus (3D rendering) leaves this pci subsystems unusable (kernel-oops). The dmesg message is 

dmesg | grep nobody
# irq 11: nobody cared (try booting with the "irqpoll" option)
  • Solution: add irqpoll as kernel parameter

Usplash

Direct rendering is broken, if you use usplash.

  • Uninstall usplash

Bios

The bios is buggy. I use the latest Version 3.110 1FETF1WW of 2004-11-16.

  • Use this DSDT.zip (contains the fixed DSDT.aml for the above BIOS), unzip it and put it into the /etc/initramfs-tools directory. Afterwards you have to recreate your initramfs (later in this section you have to do this again because of removing usplash, so to safe time you can skip this for now).
sudo unzip /wherever/DSDT.zip -d /etc/initramfs-tools
sudo update-initramfs -c -k all

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

Additionally you HAVE TO boot into save graphics mode and fix the xserver like described as followed.

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.

modules

root@ibmr31:~# lsmod | grep agp
intel_agp              25620  1 
agpgart                35016  3 drm,intel_agp

X11

Trackpoint

The trackpoint can be configured specially for scrolling in conjunction with the middle mouse button. See the xorg.conf in one of the following sections.

Please read the following article for more informations about using the trackpoint: Thinkwiki - Configure the TrackPoint
