Dat Chu's questions

I found out that since my brand new Alienware M17xR3 laptop is running Intel Sandy Bridge, I have two options to get it to work:

1. Run 11.04 which has experimental Sandy Bridge support in the kernel
2. Disable nVidia Optimus if I want to use nvidia driver

Option 2 is not possible because there is no option in the BIOS even though I have already updated to the latest version from Dell's support site.

Thus, it comes to my question: my attempt to install 11.04 works until I have to reboot. After which all I see is a brief image of the Ubuntu logo with 5 dots. Then, the screen keeps flickering like crazy with different colors. How do I boot up my Ubuntu with a barebone, no frill so I can keep running apt-get upgrade every couple of days?

I have an Alienware M17x R3 laptop with 460M nvidia card. I just got it brand new from Alienware today. Running nvidia driver doesn't work in 10.10 (GDM doesn't load at all), so I switch back to nouveau driver and upgrade to 11.04.

Once the upgrade finishes, when the computer boots up (after GRUB), the screen will continuously flickers like color-changing neon light.

Is my computer not Ubuntu-compatible?

Desktop forgets theme?

I reinstalled my Ubuntu box with 10.10 (after my dabbing of 11.04 turns out to be a futile experience). The box is clean. I install the typical packages (Google Chrome, Dropbox, build-essentials, ...).

However, now whenever I login into GNOME. The GNOME panels and decorations look weird. They don't like they have the ambience theme on. Even if I choose the Ambience theme of Ubuntu, the theme is not applied.

Currently my desktop looks very ugly. All I want is my default Ubuntu looks back.

I am trying to copy a .tar.gz file from a remote host. If I mount that host using Krusader and copy it takes a lot of time. However, if I use rsync, it is about 5-6 times faster. How come? Is there a way that I can take advantage of this speed while still be using Krusader (or a similar tool)?

I know that using Alt+F7, I can use the keyboard to move the window around. I can also use the "Grid" plugin of Compiz to position quickly the window around my current monitor. The grid plugin doesn't seem work across monitor however.

What I need is a quicker way to move the current window to the other screen. In my current dual-monitor setup, I find myself needing to move the focus window to the other monitor as I focus on working on something else (and move it back afterward).

If I use XMonad (or other tiling managers), this would be rather easy. However, many applications that I use (Gnome Do, MATLAB, image viewers, custom apps that I write, ...) do not work well with a tiling manager.

So my question is: is there a shortcut key combination that moves the currently focused window to the other monitor (and back)?
