No backlight at login, and broken Plymouth on Acer Aspire One D260 (acpi)

[Kazade]

When booting an Acer Aspire One D260 with UNE 10.04 LTS (2.6.32) there are two problems during boot. Firstly, Plymouth displays the VESA text-style boot splash and then secondly, as soon as the GDM appears the backlight switches off for around 20 seconds (it eventually comes on allowing login).

Both of these symptoms disappear when acpi=off is added a kernel option at GRUB.

Hi Kazade,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I've tested the latest mainline kernel (2.6.36) Plymouth is now displaying correctly, but I'm still left with no backlight at GDM for about 10-30 seconds.

I have similar problem (Acer aspire one Happy) in installing Ubuntu Netbook 10.10:

Also seeing this issue on a new install of Mavrick 10.10. what else needs to be done to confirm it?

[Kazade (kazade)]

Still happening with Maverick running the 2.6.38 mainline kernel

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
