Notes
Souncard
The soundcard did not work out of the box. Edit /etc/modprobe.d/alsa-base Add the line: "options snd-hda-intel model=acer"
Enable the gutsy-backport repository Goto System >> Administration >> Software Sources >> Updates >> Unsuported Updates (gutsy backports)
Install linux-backport-modules-generic apt-get install linux-backport-modules-generic
Sound should be working now.
Wireless
Allthough the Acer manual says that the laptop contains a Intel PRO/Wireless 3945BG card lspci reports it as an Atheros Communications, Inc. AR5006EG 802.11 b/g Wireless PCI Express Adapter (rev 01). With the ath driver modules ath_pci and ath_hal the card did not appear in the network tools like ifconfig and iwconfig. dmesg reported an HAL error 13 for the ath_hal driver, saying something about an unsupported version. To work around this the ndis wrapper can be used.
Install the ndiswrapper utils and the gtk interface. apt-get install ndiswrapper-utils ndisgtk
Blacklist the ath drivers by adding them to the /etc/modprobe.d/blacklist file blacklist ath_hal blacklist ath_pci
Download the net5211 windows driver from the internet and unpack the zip file
Run ndisgtk and install the driver
I needed to reboot to make the connection appear
After using wireless for some time I noticed that wireless sometimes worked and sometimes not. After some searching I found out that the wireless card can be switched off, there is actually a key on the keyboard for it. To make this work install acer_apci 0.11.0. I needed to pull this from the git repository.
S-video
The s-video output only seems to work when the cable is connected at boot. When the s-video port is switched off with xrandr it can not be switched on again. The screen flashes a few vague lines but stays black afterwards.
Frame buffer
The frame buffer does not work since the kernel team disabled all frame buffer modules. This is not specific to this laptop.
Laptop overheats
After resume the laptop sometimes becomes to hot while watching video. acpi does not seem to report the correct temperature. To diagnose I installed lm-sensors and executed sensors-detect, added coretemp to /etc/modules and use 'sensors -t' to see what the temperature is of the CPU's. There is also an applet called 'sensors applet' to show the reported temperatures in the gnome panels.
Not tested
- Firewire
- Modem
- Mic (I read somewhere that it does not work)
