Another Ubuntu Question (Kernel)

[Jafo]

I was looking at some guides to install Beryl/Xgl/Compiz, and the first thing the guides say is to make sure the kernel matches the processor as the first step. BerylXglOnDapper - Ubuntu Document Storage Facility

How do I go about knowing the kernel I have? I have an AMD 64 4000+ but how do I find out the kernel that matches? That seems to be the step left out or maybe I'm just an idiot (take your pick). I am new to linux (Ubuntu).

I'm by no means a Linux guru either (we have yurimxpxman for that), but I think it is referring to 32-bit and 64-bit versions depending on the features of your processor. In your case, you have an Athlon 64 that is a 64-bit processor so you should be able to use the 64-bit version.

Well, to answer your question, the command is uname -a. However, this really isn't necessary. Blake was right on the money when he said they're referring to the CPU architecture, and not the kernel version.

But regardless of your kernel's CPU architecture, Beryl will perform best after you perform the following:

• Install the nVidia drivers from the System Tools section of the Add/Remove wizard (Applications > Add/Remove).
• Follow this guide:
  
  

  Creating the script
  
  Open a terminal. Execute:
  

  gedit ./beryl-install-script
  

  Now, copy and paste the following script into the window:
  
  

  #!/bin/bash
  if [ $UID -gt 0 ]; then
   echo "You must run this script as root.";
  else
   cp /etc/apt/sources.list /etc/apt/sources.list.backup.beryl-script
   cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup.beryl-script
   echo "deb Repository containing nVidia binary drivers for Ubuntu Edgy edgy stable" >> /etc/apt/sources.list
   wget http://nvidia.limitless.lupine.me.uk...pine.me.uk.gpg -O- | apt-key add -
   aptitude -y update && aptitude -y install linux-restricted-modules-$(uname -r) nvidia-glx
   nvidia-xconfig --add-argb-glx-visuals
   echo "deb Ubuntu Beryl Repository edgy main" >> /etc/apt/sources.list
   wget http://ubuntu.beryl-project.org/root@lupine.me.uk.gpg -O- | apt-key add -
   aptitude -y update && aptitude -y dist-upgrade
   aptitude -y install beryl emerald emerald-themes
   echo "[Desktop Entry]
   Encoding=UTF-8
   Name=Beryl Manager
   GenericName=3D Window Manager
   Comment=Beryl Manager daemon
   Icon=/usr/share/icons/hicolor/scalable/apps/beryl-manager.svg
   Exec=beryl-manager
   Terminal=false

   StartupNotify=true

   cp /etc/xdg/autostart/beryl-manager.desktop /usr/share/applications/beryl-manager.desktop
   cp /etc/xdg/autostart/beryl-manager.desktop ~/Desktop/beryl-manager.desktop
   echo -e "\n\nBeryl is now installed.\n\nTo run Beryl on Ubuntu startup, please add beryl-manager to your\nstartup programs (System > Preferences > Sessions, and click on\nthe \"startup programs\" tab). Afterwards, please reboot.\n\nBackups of /etc/apt/sources.list and /etc/X11/xorg.conf were made:\n    /etc/apt/sources.list.backup.beryl-script\n    /etc/X11/xorg.conf.backup"
  fi;
  

  Subsequently, save the file and close gedit.
  
  Running the script
  
  Run the following commands:
  

  sudo chmod +x ./beryl-install-script
  sudo ./beryl-install-script
