Guys,
Can anyone else confirm seeing display "Flicker" on startup with the new kernel and nvidia driver? What I mean by "Flicker" is that dark bands 1/8-1/4 screen wide (vertically) will appear as horizontal bars for a fraction of a second for the first few minutes after boot. (It is not hardware warming up/etc.. -- it happens on reboot as well and this box runs 24/7)
The bars appear causing what looks like an old vertical timing sync problem on a CRT monitor, even though this is LCD. I am running dual-head and have seen other posts suggesting the problem is primarily a dual-head problem.
After install of the new kernel and nvidia driver (2.6.37.5-1 & nvidia 270.30-3) the flicker was really bad, to the point I didn't think it was ever going to quit. The display has settled down, but I still get the flicker every time I switch desktops. (switching from desktop 1 -> desktop 2, with kpager)
I don't know what software package may be at the bottom of this? (Xorg? Nvidia?) I would like to know if anyone else has experienced this and if you have any thoughts on which package it may be. Thanks.
With 2.6.38.1 and nvidia 270.30 I get a very strange artifact at the start-up of KDE, just about a second when it makes the desktop, then everything seems normal. With OpenBox it's all good here.

kernel 2.6.37.5-1 nvidia 270.30-3 kde 4.6.1
When I run single laptop screen or laptop screen + HDMI I have no problems. GeForce GTS250M.
KWin does crash if I use cover flow to swap windows, but I doubt that is related.
It may be a card-specific or similar issue?

Possibly? This is a standard old 8600GT with 512M of GDDR3. It has been rock solid with all driver up to the last two months or so. I'm suspecting the new xorg changes that have also caused problem not only with nvidia, but ATI as well.
Thanks for the input. I'll keep poking around.

I am running similar hardware with similar drivers in a dual head (twinview) setup with no issues as described now or ever in the past. I use two 1680x1050 displays connected via DVI cables. Package versions are below but are the standard testing packages. I don't run KDE, just XMonad and xcompmgr.
$ lspci | grep GeForce 02:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8600 GT] (rev a1)
$ pacman -Qi nvidia | grep Version Version : 270.30-4
$ pacman -Qi kernel26 | grep Version Version : 2.6.38.1-1
Regards,
Mike

Thank you Mike,
I'm running 1920x1200 primary and 1680x1050 secondary. I wonder if the difference in size is causing problems now where in the past it did not? Otherwise, our hardware is very close:
lspci | grep GeForce 01:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8600 GT] (rev a1)
And I'm just running the current software:
pacman -Qi nvidia | grep Version Version : 270.30-3 pacman -Qi kernel26 | grep Version Version : 2.6.37.5-1

Is it probably related to this bug? https://bugs.archlinux.org/task/22967
