[Bug 448911] [NEW] Console screens unusable, filled with random colors

 

Public bug reported:

Binary package hint: xorg

When I switch to a text console with ctrl-alt-Fn, I get a background
screen filled with multicolored random pixels. I am able to log in
(despite not being able to see what I'm typing), and can switch back to
X with alt-F7, and see the login with 'who'. I believe this system is
using a Openchrome driver. This has been happening at least since the
Karmic beta release. This system has a Jetway 625EMPxxx or 625EMWxxx
motherboard with a VIA chipset. The graphic controller is

CLE266] integrated CastleRock graphics (rev 03)

This is also happening on my other Karmic test system, an Averatec 3280
laptop. The behavior switching into and out of a text console is
identical to what I see on this system. The laptop's graphic controller
is
