Current Issues
Video
To have correct resolution and 3D acceleration enabled, you must use proprietary drivers by choosing: System > Administration > Hardware Drivers and enabling "NVIDIA Accelerated Graphics Driver" option.
Audio
The internal microphone provided with Crystal Eye webcam is not working neither under Ubuntu 8.04 (Hardy) nor under currently developed Intrepid.
With old kernel 2.6.24-19 the microphone jack was working, but with kernel 2.6.24-21 it's not working either.
See bug #269294
Wireless
Inegrated ethernet wireless controller (Atheros Communications Inc. AR242x 802.11abg) is not supported by madwifi-hal drivers provided in Ubuntu 8.04.1, you can manually install a newer version as explained on madwifi.org to fix this.
Note that in or
You can download latest snapshot of madwifi drivers (0.10.5.6) from here. This will give you latest revision available. Tests have been performed with revision 3861, that you can eventually download from here, but newer revisions should work as well.
Unpack the tar file with sources into a folder called madwifi, open a terminal, cd into the folder you just created and execute following commands (those preceded by # are comments and must not be ignored):
sudo su # enter your SU password # Now let's make sure you have everythign you need to compile the drivers. apt-get install build-essential perl apt-get install linux-headers-$(uname -r) # disable interfaces ip addr # this will list your network interfaces, look for those called ath or wifi ip link set ath0 down ip link set wifi0 down #Repeat these 2 ip lines for every MadWifi device you have (ath1, etc) cd scripts ./madwifi-unload ./find-madwifi-modules.sh $(uname -r) cd .. make make install depmod -ae modprobe ath_pci
Wait a while and the wireless should start to work. If not, reboot your laptop.
The fix appears to be incorporated into Intrepid, but this has not been tested. See bug #224498
Wireless activity LED
Wireless LED does not work properly. This can be tweaked as explained here.
Open a terminal and execute these commands:
sudo su sudo chmod a+x /etc/rc.local gedit /etc/rc.local
Add these lines just above the string exit 0 (below doesn't work).
sysctl -w dev.wifi0.ledpin=3 sysctl -w dev.wifi0.softled=1
Save and reboot.
The 2.6.27 kernel does not appear to have these options anymore (earlier kernels do).
