Re: shake 3 how to install
Are you talking about the resolution of the console/terminal? (the black screen with text)
Or the window manager? (Windows-like interphase..)
If you are using a wm, then is it KDE or GNOME, etc..? Try to find this out.
Each one will have a hardware settings option (located in slightly different ways)
KDE allows for easy access to the bootloader, (ie: LILO [Linux Loader] or GRUB)
The boot loader will then be "told" by your settings to load a FrameBuffer which I believe is whats necessary to load the "console" or "terminal" with a better, nicer resolution.
If it is the console, I've only seen framebuffer support up to 1280x1024 (which is what I use)
If you wish to have a resolution in your windows manager, then you should be able to find a displays option under your "system settings" or "system configuration". From there you can setup your video modes/resolutions.
BTW I am not a very experienced or knowledgable Linux user, but I hope this helps at least a little.
