"Display Brightness“ in the Market. It won't fix your bug, but it makes it easier to adjust your display brightness. Instead of toggling thru 4 or 5 settings, just touch the side of your screen to set brightness -- bottom for dim, half-way up for mid, top for as bright as it can get.

Thank you desertknit, the Display Brightness app actually fixed my problem (at least so far). I had tried two other similar apps before (lux and Notification toggle). With Display Brightness though my phone stays bright even after being woken up.out of sleep! Woo!
update: i said "reboot" but that was actually a power cycle. i rebooted using power key plus volume-down key as mentioned elsewhere in this thread and that is working longer now than yesterday. note that the phone takes a screenshot before the boot sequence.
update: problem returns after a couple hours. no joy.
kdavidb, did you try the free Display Brightness app in the app store? That has fixed the problem for me.
I, too, have this issue and it severely p!ss$s me off... Stock ROM--w/ root.
I use a toggle switch to set my screen brightness. The percent brightness (30% most of the time) stays at whatever I last had it set at, no matter what. I actually have all my toggle switches at the top of my notification drop down so it is always accessible using widgetzoid but there are several apps in play store that do the same thing.

I had this exact same issue with my Razr MAXX with the same exact symptoms. I searched all over and not one person seemed to have the cure, so I suffered this problem for days. However, I was able to discover the fix on my own. No more dim when waking the screen up. I can't say for sure exactly which step fixed it but I will list what I did to solve the issue:
1. Power down your Razr.
2. Power up your Razr.
3. Hold down volume up + volume down buttons at dual core screen.
4. Keep holding all the way through animation screen.
5. This will put your phone into safe mode. You will know this because the words "safe mode" will be in the bottom left corner.
I don't know if the simple act of putting my phone into safe mode cured it but I noticed that my phone stayed bright when I put it to sleep and woke it at this point. However, by the fact that it functioned normally in safe mode, I figured the culprit might be one of the apps that start at boot in normal mode. Therefore, I went into settings -> apps -> and cleared the data caches of a couple apps that I felt were capable of altering the screen brightness. To be specific, "Light Flow" (an app I downloaded), and "Emergency Alerts".
I get a strong suspicion that of those two, Emergency Alerts may be the one that was screwing things up since I had it pop up a few times before my problem started. In any case, after I did this and rebooted my phone into normal mode, the problem was completely fixed. I hope this helps a few people out.
Wow, thank you so much luckyguess and thank you for sharing this very valuable information. This issue has plagued some for quite some time.
And btw, welcome to the forums! Don't be a stranger!
Awesome! I just did as you directed and so far so good. I, too, have Light Flow.
What made you suspect those 2 apps?
