Waiting for udev events sometimes yields no graphics driver

So I am having what looks like a common problem among these udev event problems.  It started about a week ago: when I boot up, the sequence gets to "Waiting for udev events to be processed" and then the screen goes blank because (as I understand) another graphics driver is being started to replace the low-resolution one that I have right after grub passes the baton.  Unlike normal though, the screen doesn't come back with nice high resolution, it just lights up nice and black and I get nothing.  I have determined that in this situation I can still login (blindly) and tell the system to reboot and it totally works.  Adding "nomodeset" to menu.list in the grub directory fixes this, but I don't really consider this a great solution.

Now here's the strange thing:  This problem doesn't happen every time I boot up.  Originally I just killed my laptop with the power button and the next time I booted it everything was fine.  Now it is taking more tries to get the high resolution driver successfully set up, like 5 or more.

Is there some further diagnostic I can run to find out what the problem is?  Could it be failing hardware?

All the hardware in my Dell Inspiron E1505 is 5 years old except the hard-drive which I replaced earlier this year.

This comes from lspci (I think it's the right entry):

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

It looks like this is my video driver (from modinfo video):

filename:       /lib/modules/3.1.0-4-ARCH/kernel/drivers/acpi/video.ko.gz
license:        GPL
description:    ACPI Video Driver
author:         Bruno Ducrot
alias:          acpi*:LNXVIDEO:*

parm:           brightness_switch_enabled:bool
parm:           allow_duplicates:bool
parm:           use_bios_initial_backlight:bool

Am I in the wrong forum? Or maybe my computer is just toast.

Re: Waiting for udev events sometimes yields no graphics driver

I'm having a similar problem with my Dell Inspiron 1525 laptop, after doing a 'pacman -Syu' today, after an upgrading lapse of maybe 3-4 weeks.
It's frustratingly erratic for me too, but adding 'nomodeset' to the kernel line in GRUB's menu.lst seems to work so far.
I found other folks complaining at https://bbs.archlinux.org/viewtopic.php?id=128487 and https://bbs.archlinux.org/viewtopic.php?id=123718, for example.
lspci for me shows:

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 0c)

and 'modinfo video' yields:

filename:       /lib/modules/3.1.1-1-ARCH/kernel/drivers/acpi/video.ko.gz
license:        GPL
description:    ACPI Video Driver
author:         Bruno Ducrot
alias:          acpi*:LNXVIDEO:*
depends:        
vermagic:       3.1.1-1-ARCH SMP preempt mod_unload modversions 686 
parm:           brightness_switch_enabled:bool
parm:           allow_duplicates:bool
parm:           use_bios_initial_backlight:bool

I hate video problems!

Re: Waiting for udev events sometimes yields no graphics driver

Am now following advice from https://wiki.archlinux.org/index.php/Intel and have amended my kernel line in /boot/grub/menu.lst thus:

- removed: vga=791
- added: i915.modeset=1
- added: SVIDEO-1:d

and things seem good after a few reboots and shutdowns.
