[lucid] xorg crashes on start, after last update

And I attach the lastest update log

Same here.
but if I use the current ati driver from git (http://cgit.freedesktop.org/xorg/driver/xf86-video-ati) it works again (: .. maybe we need an versionupgrade?
(Radeon X1400 Mobile & X1300)

The problem is related with the open source driver ati. I activated 'fglrx' through jockey-text and I can work normally.

I use:

$ lspci
...
01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics]
...

I had the same problem: after the upgrade when logging the monitor turns off and on several times but without show login screen. I solved downgrading xserver-xorg-video-ati and xserver-xorg-video-radeon with versions downloaded from:

https://launchpad.net/ubuntu/+archive/primary/+sourcepub/944871/+listing-archive-extra

I have a Sapphire Radeon 4850:

01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850]

Next are some logs.

P.S. in xorg log I read

(II) LoadModule: "ati"
(WW) Warning, couldn't open module ati
(II) UnloadModule: "ati"
(EE) Failed to load module "ati" (module does not exist, 0)

downgrading the two packages suggested by jiveaxe made my system boot normally again...
