Kernel Upgrade (to 184.108.40.206) broke the ATi Catalyst drivers . . . no graphics
Had to completely re-install the original pre-final on an external USB hard-drive on my desktop machine which has a pair of ATi Radeon HD3870 graphics cards . . . after following the Blog instructions about how to upgrade the kernel from 2.6.29.x to 2.6.30.x (which were straghtforward and easy to follow).
This family of higher end ATi Radeon HD cards *require* the ATi drivers for Xorg to work. Without them, one gets the "Black Screen of Death" shortly after using the "startx" command. Installing BT4 requires booting from the pre-final DVD into "safe graphics" mode to get to the installer script (on the desktop). No download (apt-get install . . . ) of either the ati-driver package or backtrack-ati package would fix it . . . including running the make.sh to recompile the drivers.
As posted in greater detail in another thread about ATi-Stream . . . the backtrack-ati package has the proper ATi-drivers for ATi-Stream (not the separate ati-driver package which breaks ATi-Stream). The pyrit upgrade also breaks ATi-Stream.
Until the ATi drivers are fixed for the new kernel and ATi-Stream . . . it's going to have to remain running the 220.127.116.11 kernel. Not that BIG a deal to me . . . but thought I would post this to warn others that have ATi Radeon HD graphics. If someone comes up with a "fix" I can perform for the fglrx (ATi) drivers . . . I'd be very happy . . . as I've exhausted everything I know to do to try to get the required ATi drivers working in the new kernel.
I know the kernel upgrade is ultimately a Good Thing that will fix a number of other issues . . . a few other things will have to catch up with it to work right.
