For those of you with Intel Video cards... i8xx/i9xx. Debian Sid (unstable that is for those that don't know) just updated to:
xserver-xorg-video-intel 2.8.0-1 X.Org X server -- Intel i8xx, i9xx display driver
and along with
libdrm-intel1 2.4.12-1 Userspace interface to intel-specific kernel DRM services -- runtime
Those two things in combination with:
linux-image-2.6.30-1-686-bigmem 2.6.30-3 Linux 2.6 image on PPro/Celeron/PII/PIII/P4
The "required" GEM stuff isn't capable of running with the Kernel in PAE memory mode. Means your Intel Xorg Driver goes SOFTWARE RENDERING ONLY, meaning your system just started feeling like a 386SX16 with 16MB of memory and 256K Video Card.
Beware the thing that fixed it for me was listed in bug #538283
http://bugs.debian.o...rt.cgi?bug=538283
Also, after adding the experimental/sid line from:
http://wiki.debian.org/DebianKernel
And installing the latest kernel the source for "Latest from /dists/trunk (targeted for experimental/sid)" being:
linux-image-2.6.31-rc4-686-bigmem 2.6.31~rc4-1~experimental.1~snapshot.14009
That now means I have the GEM setup (Graphic Engine mumble) which beginning in 2.6.31.rc4 works in PAE mode.
P.S.
I also had to update the BIOS for my Laptop and the Video Card... umm DANG, Windows ONLY. Actually Windows 2000 in the Recovery Partition only could run the Flash update. SOOOO, 68 Lenovo Updates later, 97 Windows updates later, mixed in with 15 reboots for WindowsXP, totalling 1.2GB of downloads, I was finally able to boot into the recovery partition and flash my BIOS with the latest revisions for the motherboard and Video card.
I guess that is what you get for not booting/updating WindowsXP/Recovery partition since September 2007.
