Last year I got a Dell Inspiron 6000 with a 15,4″ WXGA TFT-Display (1280×800) and the Intel shared memory graphic-chip.
Installing Ubuntu 5.10 (the Breezy Badger release) on it worked like a charm.Just insert the CD and follow the instructions, afterwards you have a working Linux, even featuring Suspend-to-RAM. I haven’t tested the modem (as I don’t need it), but it’s said to be working.
The only thing definetely not working is the SD-card slot, it’s neither supported by the Kernel nor does a driver exists. I managed to get the SD-card slot working, read here.
As I’m using a WPA-protected wireless-network at home, I had to install the lateste driver for the centrino wlan-chip (ipw2200). Of course, you dont’t have to do that, if you don’t need WPA, WEP-encryption works out-of-the-box. Therefore I followed the instructions found on the Ubuntu Forums, but I didn’t write a shell script, because changing my /etc/default/wpasupplicant like that worked for me:
ENABLED=1 OPTIONS="-D ipw -i eth1 -c /etc/wpa_supplicant.conf -Bw"
Note, that eth1 is my wireless network-interface, that might differ on your installation.
Actually, that’s all I had to do to make my Inspiron work with Ubuntu.
