I've tested two similar laptop hardware.
All works after fresh feisty install (sound, ati fglrx 3D after activate it in admin system menu).
Here are some fix for suspend / hybernate and others tools/ tweaks to have a better laptop support (as ati under-clock mode once on battery).
Dell inspiron 6400
1.8GHz dual core processor
1280x800 widescreen
ATI X1400 mobility 128MB
1024MB Ram
ipw3945 wireless
Dell inspiron 9400
1.66GHz dual core2 processor
1440x900 true life widescreen
ATI X1400 mobility 128MB
1024MB Ram
ipw3945 wireless
- Launch feisty with live cd
- Swith to tty1 at X11 error. (ctr-alt-F1)
- sudo apt-get install xorg-driver-fglrx
- sudo aticonfig --initial
- sudo aticonfig --overlay-type=Xv
- sudo /etc/init.d/gdm start
- install feisty
- you need to reinstall xorg fglrx after first reboot
- sudo vim /etc/default/acpi-support
MODULES_WHITELIST="fglrx ipw3945"
POST_VIDEO=false
SAVE_VIDEO_PCI_STATE=true
- sudo vim /etc/network/interfaces
- remove all lines after lo. cat /etc/network/interfaces :
auto lo
iface lo inet loopback
Change ati clock frequency each time laptop switch from ac to battery.
TODO : actually need to make a xhost+ from client session , not secure.
- sudo vim /etc/acpi/ac.d/20-ati.sh
#!/bin/sh
aticonfig --set-powerstate=3
- sudo chmod 755 /etc/acpi/ac.d/20-ati.sh
- sudo vim /etc/acpi/battery.d/20-ati.sh
#!/bin/sh
aticonfig --set-powerstate=1
- sudo chmod 755 /etc/acpi/battery.d/20-ati.sh
You can list all powerstates options with aticonfig --list-powerstates command.
- sudo apt-get install i8kutils gkrellm gkrellm-i8k
- sudo vim /etc/modules and add i8k force=1
- get feisty computertemp package here : http://computertemp.berlios.de/
- dpkg -i computertemp_0.9.6.1-0ubuntu1_all.deb
You can change cpu frequency with left mouse click on gnome cpu applet
This fix also this :
after resuming from suspend or hibernate cpu applet don't show good cpu frequency clock and stay at full speed.
- sudo dpkg-reconfigure gnome-applets
- vim /etc/modprobe.d/blacklist
- add : blacklist pcspkr
- open sound mixer
- check capture display option in Edit / Preferences menu
- Micro phone audio recording is disable by default ("Toggle audio recording") : you need to enable it. Capture volume level can be set to 0 to have no sound disturb.
- now there is no more crash inside ardour or rosegarden and others jackd applications.
