[Nix-dev] Problem with ATI graphics card

[Marco Maggesi]

Hi,

I'm trying to reinstall nixos on an my desktop computer (after an HD
replacement due to a bad corruption).
The installation process goes smoothly, but after reboot (during Stage 2)
the screen become unreadable (a set of randomly distributed coloured
pixels).

This happens under various different configurations:
- with my old configuration.nix
- with a brand new configuration.nix created by the installation scripts
- with xserver enabled and disabled

When booted from the installation/rescue CD the graphics card works
normally, either in text mode and with x11.

Here is the line of output of lspci that describe the graphics card:

01:00.0 VGA compatible controller: ATI Technologies Inc RV610 video device
[Radeon HD 2400 PRO]

What could I do?
Thanks,
Marco
