This page is for tracking issues related to Ubuntu 8.04 on Dell platforms.  If you don't see your issue here, you've got many options:

Generic (Affects more than one platform)

Description: No sound after software upgrade ( i.e kernel 2.6.24-25)
Systems Affected: Any systems with a software modem
Impact: No sound from speakers or headphones.
Fix: 
  1. Enable the dell-team PPA.  Visit this link for details:
    Dell Team PPA
  2. Use synaptic or a package manager to install the package called hsfmodem
  3. Check if the package called build-essential is installed and if not install it.
On reboot you should have sound again.

NOTE Pre-built modules are currently provided for kernels upto 2.6.24-24  so the build-essential
package was not necessary until kernel 2.6.24-25 was introduced.

Description: WiFi LED on system does not work.
Systems Affected: All intel wireless hardware
Impact: WiFi LED on system does not turn on when WiFi is in use, but wireless still works.
Fix: Install linux-backports-modules for your kernel. For example, if running kernel 2.6.24-16-generic: 

$ sudo apt-get install linux-backports-modules-2.6.24-16-generic


Description: SATA Drive isn't detected in IDE mode
Systems Affected: Inspiron Desktops
Impact: Unable to install or Boot Ubuntu 8.04 when hard drive is in IDE mode
Bug: https://bugs.launchpad.net/dell/+bug/153702
Fix: Two workarounds are available.

1) Switch your hard drive to RAID mode in the BIOS

2) Add the all_generic_ide parameter to your /boot/grub/menu.lst and to your installer command line

 

Description: System fails to suspend more than once. This is caused by a kernel bug in the USB subsystem that shipped with kernel 2.6.24. It is resolved in 2.6.26.
Systems Affected: Studio families
Impact: After the first suspend, the USB subsystem is hung.
Fix: Unload ehci-hcd before suspending. 

$ echo SUSPEND_MODULES="ehci-hcd" | sudo tee -a /etc/pm/config.d/unload_modules
