Error: “end_request: I/O error, dev sr0, sector xxxxx” – Linux

Error:

end_request: I/O error, dev sr0, sector 537392

If you’re getting a similar error filling your screen once you’ve installed Ubuntu, don’t panic. It’s pretty common which is basically because Ubuntu (or any other Linux distro) can’t control your CD/DVD drive properly, it’s probably trying to open/close it but doesn’t know if it has or not. The problem is that you don’t get to see what Ubuntu wrote before because it’s filled your screen up with this error.

If you’ve just installed Ubuntu this probably happened when it wanted you to take the disc out and close the cd tray (if there is one) then hit Enter to finish the installation, so just do that and ignore this error.

HowTo: Switch the Window Menu Buttons Back to the Right – Ubuntu 10.04 / 10.10 / 11.04

I’m not an OSX person and personally prefer my minimise, maximise and close buttons to be in that order on the right, which they are not as default on the new Ubuntu 10.04 (Lucid Lynx) so here’s how you can swap them back to their rightful place (pun intended).

This can be done either of two ways:
Use the following one line command to edit gconf (for more info type man gconftool):

gconftool -s /apps/met>gconftool -s /apps/met>gconftool -s /apps/metacity/general/button_layout -t string menu:minimize,maximize,close

OR
Using gconf-editor (the GUI version):

  1. In terminal type: gconf-editor
  2. Navigate to /apps/metacity/general
  3. Change button_layout to: menu:minimize,maximize,close
  4. Hit enter and you are done.
