This is a re-re-re-re-run of a previously unsolved problem....
I have an ACER Aspire 5732Z laptop, Dual core Intel Pentium T4400 w/4GB memory. The Display OpenGL Renderer is listed as a "MESI DRI mobile Intel GM45 Express Chipset x86/MMX/SSE2" by the hardinfo utility and when I installed the following kernel I get a blank screen (no video at all - it looks like power was shut off) part way into the boot (before the new modules for the new kernel would compile):
I just tried kernel-220.127.116.11-pclos3.bfs with all of the latest repo updates as of 8/20/2011. (including all the video drivers).
When I booted the new kernel for the first time I let it sit until all the disk activity was done [the wireless network light was on as if it was active tho] and then did a 4 finger keyboard shutdown and rebooted the new kernel again with the "NO ACPI" option. It tries to boot but hangs for a minute trying to mount my remote NFS file systems [but the screen stays turned on!] --- but it appears to have no network access (either wired or wireless) and then aborts to the command line login.
I've been running kernel 18.104.22.168-pclos6.bfs still with all the other current updates and I've tried every kernel update after that which has ended up with a "shut off LCD" screen. The last 4 kernel upgrade attempts always crashes to the command line (when using the NO ACPI kernel boot option) or no video (screen is shut off) if I let it boot normally.
Do I have a mutant video card on my laptop that is no longer supported?
