Release notes for 12.10 - some known problems with video drivers

Some of the legacy video drivers are currently non-functional and aren't 
likely to be resolved any time soon. If at all.

Trident Cyberblade - xserver-xorg-video-trident

This driver has a whole array of problems.

As the VESA driver doesn't work with this chip set the only solution is 
to remain with 12.04.

Intel i810 - xserver-xorg-video-intel

This driver currently segfaults on this chipset.

SiS M650/650 - xserver-xorg-video-sis

This driver currently loops around the login screen for the M650 or 
produces a blank screen 650.


Before upgrade from 12.04 blacklist or delete the video driver and use 
Xorg.conf or RandR to set the correct resolution etc. if necessary.

A new install can only be accomplished from the alternate ISO.  On 
reboot go to Recovery Mode and delete/blacklist video driver.  On reboot 
create suitable xorg.conf or use RandR to get correct resolution if 

There may be problems with other legacy video chips for which the 
blacklist/delete workaround may well work.
