Hi and thanks in advance for any help.
I have three different computers all with different intel graphics cards and three different issues (well two issues I guess, since one works properly).
Computer A (Shuttle X50 v1): 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)
Computer B (Shuttle X50 v2): 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller (rev 02)
00:02.1 Display controller: Intel Corporation N10 Family Integrated Graphics Controller (rev 02)
Computer C (PioneerPOS StealthTouch-M7): 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Computer A: Black screen at triggering UDEV events. i915.modeset=0 does get it to boot up, but can't display proper resolutions and uses VESA driver not Intel.
Computer B: Works fine, no perceptible issues.
Computer C: Black screen at triggering UDEV events. i915.modeset=0 does get it to boot up, but the Xserver will only use the VESA driver and does display in native resolutions with no video acceleration. The processor is fast enough on this one I could live with the VESA driver except it needs dual monitor support.
I have searched and searched and searched and found many "solutions" from this forum and many others but none seem to make any difference for me.
Any suggestions would be most helpful.
Thanks, Hugh

Hello Hugh Johnson,
please try solution for this thread:
click
you may also try 'acpi_osi=Linux' and 'acpi_backlight=vendor' cheats
if that wont work then please boot Porteus with 'changes=' cheat in normal GUI mode. once you get blackscreen wait few seconds and then press ctrl+alt+del or force shutdown by pressing power button.
now boot any other OS which is working on this PC and upload /var/log/messages from saved changes to pastebin.com for review

Re: i915 blackscreen
Thanks for the help!
I'm focusing on computer C at the moment (since I had to ship out the other two, I'll get them back next week).
I've got a bit more info, I plugged in a second monitor to the VGA port and when the built in screen goes blank on udev it switches to the second monitor for the console and doesn't go blank, but X never starts.
I've tried all the solutions in that thread in many different combinations to no avail. I've uploaded my /var/log/messages to: http://pastebin.com/htdVMjf1
Also here is the /var/log/Xorg.0.log: http://pastebin.com/HUarSm9M
I think the problem might have to do with the vesa console graphics driver being loaded before the intel driver but you never know.

Re: i915 blackscreen
from Xorg.0.log i see that max resolution discovered on your PC is 1024x768 only (while it's 1600x900 on external monitor):
which is a bit strange.... looks like a kernel mode setting issue to me.
please post full specs of this PC: boot into text mode and run 'psinfo' script.
report should be generated on Desktop folder.
also - did you try any other modern distro on this PC?
if no then please try for example latest 'Parted Magic' and show us it's Xorg.0.log

Re: i915 blackscreen
There are two monitors one each supports different resolutions.
Here is the psinfo.txt: http://pastebin.com/8pFSZ7iU
Downloading parted magic now.
Posted after 1 day 11 hours 50 minutes 39 seconds:
Nothing seems to work, I've tried many different distros. I guess it could be hardware failure (this is an evaluation model which could have any number of issues). A client bought 10 of these, and I have access to another, I'm going to try it out today and see if it fairs any better.
