It happens quite often now, about 15 seconds a flash, really a headache.

If it's a white flash, it's because of the vbell (visual bell) feature. Put this in .screenrc to disable it:
vbell off

This doesn't fix the problem. I don't know if it's a white flash, it's very quick.

Sorry, need clarification. Are you talking about the display or the 'screen' utility?

It"s the display, and it doesn't happen in tty. Maybe it's a windows manager issue.

I switched from awesome to dwm for my window manager, but the problem persists, so it's not the cause.

Is it a intel graphics card and does it happen since 2.6.32? Then it might be this:

It's a laptop with a intel graphics, so it's a bug in kernel. How can I downgrade the kernel or apply a patch like the one mentioned in http://bugzilla.kernel.org/show_bug.cgi?id=14781 ?

or whatever version was working for you last...

Try putting "options i965 powersave=0" in /etc/modprobe.d/modprobe.conf.

The problem seems gone after system upgrade "pacman -Syu"

The problem comes back, after resume from suspend.

I tried to revert to 2.6.32.2-2, but there is an error message
error: failed to prepare transaction (could not satisfy dependencies)
:: ndiswrapper: requires kernel26>=2.6.32.3
:: tiacx: requires kernel26>=2.6.32.3
I don't know if it's safe to remove those two packages.
The patches in http://bugzilla.kernel.org/show_bug.cgi?id=14781 seem to apply to the file intel_bios.c, but my system doesn't have that file.

For the records, I also have this problem on my eeepc 901.
Flash only happens after a suspend/resume.
[root@UpEarly coda]# lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
Once in a while after a resume, my screen will go completely white and stay white. Forcing me to do a force restart. Thought it was just me. Would be nice if this got fixed.

With KMS disabled it seems better.
You don't have to force restart, going back to suspend to ram and waking it up makes the display appear again but not make the problem go away.

The problem persists even after reverted to kernel 2.6.32.2 and set the option powersave=0. This makes the system unuseable. I am thinking going back to ubuntu now.

Did you try disabling KMS?
I haven't lost my mind; I have a tape back-up somewhere.

I changed from intel driver to the vesa driver, and the problem is gone, at the price of no ttys and full screen flash video problem. Will disabling KMS cause ttys unusable?

Add the i915.modeset=0 to /boot/grub/menu.lst
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/0f756665-5129-484a-b746-35e3b7858888 ro i915.modeset=0
Then you can use the intel driver like before but the console will have low resolution.

This fixes nothing for me. It simply makes it so my X server wont start at all..
Crap, why did he have to label this thread "[SOLVED]"... Because it's not for me.
My video card is an Intel 945GME Revision 03.
