This affects 8.10 Intrepid desktop live-CD boot - currently not able to install to the hard disk.

Sony Vaio PCG-SRX51P/B notebook with Intel i815M video and 384MB RAM.

When X starts the screen becomes totally black with no cursor.

It is possible to switch to a console terminal although the usable area is a small section in the centre of the 1024x768 display.

If gdm is stopped /var/log/kern.log shows:

Disabling DRI in /etc/X11/xorg.conf helps only slightly in that X tries to reconfigure the display and gets stuck in a loop of dialog choices (very small - 6px - text too) which results in it using the 'generic' profile again which tries to use DRI and therefore the screen is blank once more.
