@Nishant, Your VIA K8M800 onboard graphics isn't supported by Beryl. You need a
good NVidia Graphics card (ATI Radeon gives more problems!!). Anyway you can
install the GNOME Vista theme in your 64-bit Ubuntu.
NOTE : Beryl is a fork of XGL
Here the procedure for installing the GNOME Vista Theme in Ubuntu:
First download the GNOME Vista theme from here ( File size 2.2 MB)
Right-click on the gnomevista.tar.bz2, choose "Open with Archive Manager",
Now click on the 'Extract' button. A dialog by name 'Extract' pops up. Click on 'Extract'
Now close the 'Archive Manager'. A directory by name Gnome-Vista is created
in the same directory. Now open the Terminal Window & type :
$ cd Gnome-Vista
Or where ever you have extracted the file , cd <directory path>
$ sudo mv glass-icons /usr/share/icons
$ sudo mv LiNsta2 /usr/share/themes
$ sudo mv Almon-dark-blue.wsz /usr/share/xmms/skins
Now from the menu , go to 'System' -> 'Preferences'-> 'Themes' or type:
$ gnome-theme-manager
This opens the Theme Preferences dialog.
Now choose any Theme from the list, click on 'Theme Details' button. In the Theme Details
dialog, click on the tab 'Controls'. Scroll down a bit & select 'LiNsta2', now click
on the tab 'Window Border', select 'LiNsta2'. Now click on the tab 'Icons'. Select
'Glass-Icons'. Click on 'Close' button. Now Your GNOME Vista theme is configured
& you can see the theme for yourself!!
Now we need to configure the skin of XMMS player. Install XMMS player in case you haven't installed it.
$ sudo apt-get install xmms xmms-skins
Wait until the installation is complete.
$ xmms
Right-click on the XMMS player, 'Options'->'Skin Selector' ->'Almond Dark Blue'.
Also change the 'Ubuntu' wallpaper to 'rotterdam_vista.jpg'. From the Ubuntu Desktop,
right-click ,select 'Change Desktop Background' . In the Desktop Background Preferences dialog
click on 'Add Wallpaper' & select 'rotterdam_vista.jpg' Click on 'Finish'.
