description |
Filed at Chris P's request, this bug is still present on both the Ubuntu 14.04 kernel (3.13) as well as the latest mainline kernel (3.17). In addition the mainline kernel causes additional issues with regards to brightness control.
I have used the boot param noapic to run Ubuntu on this laptop since 12.04, however acpi=off, acpi=noirq or acpi_backlight=vendor dell_laptop.backlight=0 all also fix the issue. Using the last option however causes poor brightness control as the dell backlight driver is not properly optimized.
