in photos app, rotation worked perfectly

Don't get confused with forcedrotation and h-d rotation many do and they are completely different.
I try to refrain from using "Portrait Mode" for this reason.

The gconftool you posted above or the lock-applet should allow the desktop to rotate.

I think maybe what you are looking at there is the helper app for the browser, which just collects and manages bookmarks. If you have an actual web page open, the set of options from the drop-down menu should be different ("New window", "Reload", "Find on page", "Save page as", "Downloads", "Details", and "Options").

But yeah, if photos are rotating correctly, then the hardware should be fine.

Hmm. At this point, it would probably be better for me to wait for someone who actually uses CSSU to comment on what is going on here...

Run in Terminal: gconftool-2 --recursive-list /apps/osso/hildon-desktop
and paste output here.

thank you very much everyone

hi, bro arcean. can pls help?

I't doesn't sound to me like you have a problem. Most of the n900 doesn't support portrait anyway. The rotated browser doesn't have all the options of the landscape. The phone has it's own rotate option. CSSU stable only allows you to rotate the desktop to portrait. The icons have to be arranged for portrait though. It doesn't do it automatically.
Feel free to correct me. I'm not 100 percent on this.

you might have a broken slide sensor. check this thread. http://talk.maemo.org/showthread.php?t=64949

Yes, that might be it! If the keyboard is open, the photos app will still rotate pictures, but the web browser will stay in landscape mode. But does the CSSU actually care about the keyboard status?

yes it does just like on the stock original firmware. if you notice that you're keyboard stays lit even if you close the slide, or if you see that you're phone automatically unlocks your screen(which is very annoying especially when it's in your pocket), and ofcourse even in phone mode does not go into portrait mode, my best bet would be you lost the magnet on which the slide sensor see if the slide is closed or open, or the sensor itself is broken. if you're lucky you might just be dealing with dust pileup between the sensor and the magnet. me not so lucky i tried cleaning the sensor and the magnet but to no avail. you can try to check it if you can open your phone. and yeah, it also sucks the life out of your batteries since the keyboars stays lit and your display always open once in while..
