dell 630m resolution

[Xurxo Fernandez Gismero]

I upgrade to dapper today and my resolution has gone back to 1024x768.
Native resolution is 1280x800.
I installed 915resolution (before i had 855resolution and it worked
flawless). 915resolution was supposed to work with my computer but it
doesnt. Also trying to edit the 915resolution file and give a new mode
like 39 with 1280 and 1024 havent work.
Any suggestion. I know more ppl on the list have this computer.
