I have successfully installed Ubuntu Linux 7.10 Gutsy Gibbon for x86 and AMD64 on my Toshiba Satellite A215-S4747 with working graphics on its ATI Mobile x1200 graphics card.
Ubuntu Linux 7.10 Gutsy Gibbon on Toshiba Satellite A215-S4747
Sound and LAN work right out of the box.
The graphics setup was very simple. Just install the 'xorg-driver-fglrx' package and then enable the restricted graphics driver in "Restricted Drivers Manager." After a reboot you should be good to go.
In order for "Visual effects" through compiz-fusion to work you have to install the package 'xserver-xgl'. And manually enable Composite Extensions in the xorg.conf file.
The wireless setup took a few more steps but was still fairly straight forward. The steps are outlined below.
Option "Composite" "1"
Instructions for Atheros wireless card:
Extract drivers and take note of where you extracted them.
After a reboot wireless should work. You should see available wireless networks in the network manager. Note: every few bootups, Ubuntu doesn't get the MAC Address for the wireless card correctly. So far it looks like the easiest way to correct this is to go into /etc/ndiswrapper/net5211 and look for the file with a symbolic link. Edit it and replace the line that says
echo "blacklist ath_pci" >> /etc/modprobe.d/blacklist
apt-get install ndiswrapper-utils-1.9 ndiswrapper-common
ndiswrapper -i net5211.inf
look for something like this:
net5211 : driver installed
device (168C:001C) present (alternate driver: ath_pci)
echo "ndiswrapper" >> /etc/modules
mac_address|XX:XX:XX:XX:XX:XXand replace the X's with your MAC address.
Adjust LCD brightness:
SD Card readerecho XX > /proc/acpi/video/VGA/LCD/brightness
Where XX is a number 0-70
Increments of 10
0 darkest, 70 brightest
Works right out of the box. Just put a card in and it works!
None of the following worked right out of the box as far as I can tell, nor have I taken the time to figure out how to get them to work. If anyone has any ideas, feel free to post comments.
