dell latitude xt graphic drivers for ubuntu 10.10 ? touchscreen?
 
Hi,

we have a laptop (dell latitude xt) on our company, and we would like to install ubuntu on it. windows 7 works fine out of the box, so the hardware is fine.

since this laptop has a touchscreen we just installed ubuntu 10.10 netbook edition 32x.

But, we do not manage to enable the touchscreen, neither the vga graphic drivers.

this is the output from lspci, if somebody cares.

I've tryied to install ati drivers 9.3 , which I downloaded and installed, unpacked and installed, builded and installed, but nothing worked. Looks like the latests version is just accepted to work on jaunty 9.04, so they are kind of old.

Aticonfig always says the same:
aticonfig: No supported adapters detected

what else I can do?

thanks.

I poked around the ubuntu forums, and it sounds like you need to edit the kernel arguments. This post had some pretty clear instructions:

Well, I didn't see the solution in the post you mention (maybe I didn't look carefully though).
So here's the solution/workaround I found in the relevant bug report here : https://bugs.launchpad.net/ubuntu/+s...ux/+bug/558378

1/ Soon after booting the computer, enter the grub menu by pressing the 'shift' key
2/ Choose the Kernel you want too boot (should be 2.6.32), and press 'e' to edit the parameters
3/ Add radeon.modeset=0 at the end of the GRUB_CMDLINE_LINUX_DEFAULT="..."
It should look like this :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.modeset=0"
4/ Press 'Ctrl+X' to finish the boot.

The proprietary drivers from AMD/ATI will not work with that GPU on any modern distribution. The open source drivers, however, should give you 2D and 3D acceleration. Before you do anything else, make sure you remove the drivers you installed.
