I've been trying to install Ubuntu on my boyfriend's new laptop. We've tried both 9.04 and 9.10, with the same results. When booting the normal install CD, it gets to the ubuntu logo with the progress bar, then has a graphics error and hangs. The alt install CD didn't work either, it said something about the CD drive being uncommon. I've tried booting into live mode in Debian and Ubuntu, from USB, and both give an endless string of ACPI errors. When I boot with ACPI=off, Debian loads just fine, but won't detect the hard drive, nor the wireless card. Ubuntu will either drop to an initramfs prompt, or go to a blank screen with a flashing underscore. DSL, however, seemed to boot without any problem, with ACPI still on :? I've looked around, and it seems a lot of people are having the same issues with Satellite models. My first instinct was to update the BIOS, but there isn't an update for this model (L505D-ES5025), and the Toshiba support website doesn't even list it.

Additionally, when I put his hard drive into my laptop, to resize the partitions, GParted didn't recognize any partitions. I think it's just something odd about the partition table, but it could be something else entirely.

I've tried everything I can think of, any suggestions?

I guess you tried live mode from the Ubuntu cd as well?

Yes. Any media gives the same errors.

BIOS...

Have you tried to set the ACPI to S1 and disable the ACPI Soft-Off in the BIOS?

Those options aren't in this BIOS.

Exactly, I have the same problem, the only to install Linux is the ACPI=off option in setup, and by then, Linux loads without it.

I have a Toshiba L505D-S986 and have the same situation, I couldn't adjust the monitor brightness, and it all depends on the ACPI.

Maybe i'll wait for a Kernel update or Toshiba release a BIOS update, because I'm not going anywhere, because I already tried everything, for the meantime, I'll get boring with Windows 7 .

Other Symptoms:

With ACPI=off
- No brightness adjustment on the monitor.
- Loads fine.
- Fan runs slower.
- Wireless card works.
- Hard drive detected

With ACPI=on
- Boot screen with a lot of errors.
- Doesn't load to GDM.

With both options, the computer doesn't restart or shutdown at all, have to force shutdown with power button, witch is no good.

With other ACPI option fails and load with ACPI=off

There is no way to adjust anything in the BIOS beside basic stuffs like Hard drive or boot order, no ACPI or power management at all.

I have this problem as well with brand new Toshiba satellite l505d-es5025 with AMD M520 turion x2

Not good manners to highjack...

You would have better results were you to start a new thread stating your problem in detail.
