A friend of mine has a PC with Windows XP / Ubuntu in dual boot. After the Lucid upgrade, Windox fails to boot (strange lines on the screen after Grub…).

TestDisk saved us:

sudo aptitude install testdisk
sudo testdisk
  1. Choose [ Create ] Create a new log file
  2. Choose windows physical disk, then [Proceed ]
  3. Choose [ Continue ] Continue even if there are hidden data
  4. Choose [Intel ] Intel/PC partition
  5. [ Advanced ] Filesystem Utils
  6. On Windows XP partition, boot sector is generally bad or non identical to backup sector (Sectors are not identical.).
  7. Choose [ Backup BS ] to copy the backup sector to the master sector.
  8. After that, quit, reboot and test.

With the last Ubuntu Lucid 10.04 come a new graphical module: KMS or Kernel-based Mode-Setting.

If you have performance problems in some games like Quake 3 or TCE / Enemy Territory, try to disable KMS.
The problem can also be with the mouse pointer (slowness, lag, delay or inacuracy).

Grub 2

Add nomodeset in /etc/default/grub then issue the command update-grub.

vi /etc/default/grub

Grub 1

Add nomodeset at the end of the # kopt line, then issue command update-grub.

vi /boot/grub/menu.lst
# kopt=root=/dev/sda1 ro nomodeset

Someone also told me that disabling KMS solved his Firefox javascript speed problem in Yahoo Mail.

Audio CD copy is actually not possible with Brasero on Ubuntu Lucid. All details in the bug report.

As a workaround, you must install cdrdao version 1.2.3, which is not yet available as a package.

To install it, you can use CheckInstall which is a bit cleaner than the old make install:

tar -xjvf cdrdao-1.2.3.tar.bz2
cd cdrdao-1.2.3/
sudo checkinstall make install

Note: the make command can fail because of missing dev packages you’ll have to install.

CheckInstall builds and installs a nice Debian package.

You can also use cdrdao directly. ps axf shows us the command Brasero is using:

cdrdao read-cd --device /dev/sr0 --read-raw --datafile /home/dooblem/brasero.toc.bin -v 2 /home/dooblem/brasero.toc

Here we go!
