Hello, I am facing the exact same problem.

Debian jessie/testing i386 updated as of 6 January 2013.

$ uname -a
Linux jessie 3.12-1-686-pae #1 SMP Debian 3.12.6-2 (2013-12-29) i686 GNU/Linux

X.Org X Server 1.14.5
Release Date: 2013-12-12

$ dpkg -s xserver-xorg-video-intel
Package: xserver-xorg-video-intel
Status: install ok installed
Architecture: i386
Source: xserver-xorg-video-intel (2:2.21.15-1)
Version: 2:2.21.15-1+b2

$ lspci -nn
00:00.0 Host bridge [0600]: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM
Controller/Host-Hub Interface [8086:2560] (rev 01)
00:02.0 VGA compatible controller [0300]: Intel Corporation
82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev

This snippet is to be used with which AccelMethod? SNA or UXA?
Section "Screen"
  Identifier "screen0"
  DefaultDepth 24
EndSection

With SNA, color gradients don't get rendered smoothly, they appear in ugly
discrete steps.

With UXA, lightdm doesn't start. I get blank screen.

So my weird workaround is: Start lightdm in UXA mode; replace SNA with UXA in
xorg.conf; log in and start session in UXA mode.

Why does UXA fail to work the first time? It only works second time onwards.

I need to get this bug solved. How can I help you debug this?
