Install Brother MFC-240C (shared on Windows) in Gutsy

I bought Brother MFC-240C yesterday for using in my home. My home network is windows network that use the same workgroup name to see each other. The printer is connected to mom's pc. Then I will add this printer to my ubuntu but the ubuntu database have no drive for this model.
After I googling a few minutes, I found this page and this page. These are the answer!
Follow these steps:
1. download LPR driver from this page. (*choose the driver for Debian, The MFC 240C model)
2. open the terminal and run this commands

sudo mkdir /var/spool/lpdsudo mkdir /var/spool/lpd/mfc240c

3. double clicks the LPR driver (mfc240clpr-1.0.0-9.i386.deb) to install.
4. download cupswrapper from this page. (*choose the driver for Debian, The MFC 240C model)
5. if everything works, the printer will show in System->Administration->Printing

if you plugs the printer on this computer(via USB). It's can work now.
if this printer is shared from other computer and want to add it via network like me.(Go to step 6.)
6. open System->Administration->Printing and click MFC204C like above image. On the right,
Click the Change button on the "Device URI" line. and Find out where your printers!.
7. Try printing the test page and see what you've done.

Slow scrolling in Beryl and Deskbar can't type problem in ubuntu

My laptop specs are Acer 5021 , ati X600 64MB VRAM , DDR Ram 768

Last week I installed aixlg+beryl in my ubuntu. Beryl is so cool. Many Effects work fine but
when scrolling the window especially Firefox. It's so slow. I don't know why.

I try disabling most effects (resize , wobbling and ...) but It's didn't fix the problem.

I google around , many people have the same problem but there aren't the solution.

Found some bugs of this in http://bugs.beryl-project.org/ticket/1

so I try installing last beryl on svn and using XGL instead of aixlg (that ubuntu recommend)

It's work!! Slow scrolling problem is fixed.

if you have the same problem and want a try. I can't guarantee this method can fix the problem.
