[Bug 221119] Re: [gutsy, hardy, intrepid] Blank screen and (EE) intel(0): overrun on pipe B! on i945GM using intel driver

[Brian harkness]

I found this another post regarding the jaunty xorg repo and I thought I
bookmarked it but I can't find it, or maybe it was here and I just could
not find it again.  At any rate, it seems to be a 'partial' solution for
me so far.

1. Downgrading the driver would not work.  I found several posts to confirm this.
2. I don't think it has anything to do with desktop effects or compiz.  I had the issue with effects on or off.

Here is what I did:
I am using Intrepid on an Asus EEE-BOX  with an Intel 945GME (posted earlier)  I added these two repos: 

deb http://ppa.launchpad.net/xorg-edgers/ubuntu jaunty main
deb-src http://ppa.launchpad.net/xorg-edgers/ubuntu jaunty main

I hit upgrade via synaptic to see what might be affected: 8 packages.
The the intel driver and some mesa related items were upgraded.  Seemed
worth a try, because as it stands now, (K)Ubuntu is pretty much unusable
if I can't trust it not to tank on stuff I am working on.

I then disabled the repo, as I know it is never a good idea to mix and
match different versions of a distro.

Being this is actually a desktop PC connected to a VGA - I disabled the
TMDS-1 output in my xorg.conf file:

Section "Device"
	Identifier	"Configured Video Device"
	Driver 		"intel"
	Option 		"ForceEnablePipeA" "true"
        Option 		"monitor-TMDS-1" "ExternalMonitor"

EndSection

Section "Monitor"
        Identifier      "ExternalMonitor"
        Option 		"Ignore" "True"
EndSection

And lastly, since I use Kubuntu, in SystemSettings --> Advanced -->
Service Manager

I stopped "xrandr detecting monitor changes," and then unchecked the
box.  In other posts, this has been reported to reduce/stop  flickering.

The screen still occasionally flickers, but the desktop and applications
are MUCH sharper.  Resizing icons on the desktop and such "re-drawings"
used to stick and be sluggish and now I don't notice that either.

So far, my performance is notably better.  I am not sure if it is more
stable yet BUT I am hoping to be able to report back that I no longer
get a blank screen where I have to reboot and lose what I was working
on!
