Acer Timeline 4810TG on Jaunty - ATI Driver

[telefunken]

I really don't know what I messed up in the code, but I copy/pasted yours, rebuilt the module as timelinex_acpi, and now it works!

I gotta recharge my battery and see how many hours I got now, without the module it was about 3+ hours in Ubuntu, and 8+ hours in Win7...

Thanks!

Nice to hear that it is working now!

For the battery time, I really like this KDE plasmoid: http://kde-look.org/content/show.php/?content=123767

With fully charged battery, Ubuntu claims to have 7-9 hours worth of battery life, that's a great improvement. If I could get it to control screen brightness it might almost be on par with win7...

Going OT a bit, but if you have any tips/tricks/tweaks to get more battery out of the 3820TG, please share

Here is a something about the brightness, it works for me: http://ubuntuforums.org/showthread.p...57#post9291657

In case you also have problems with quirky graphics on the boot splash and non-working Ctrl+Alt+F1 consoles, try this fix.

The powertop tool shows some nice power saving tips.

There are some more commands at http://linux-macbook-air-killers.blo...ine-3810t.html , but except for the wireless power saving I have not tried them yet.

One of the hybrid-graphics-linux Launchpad team members has created a Linux kernel module to call ACPI methods through /proc/acpi/call. The code is here:
http://github.com/mkottman/acpi_call
You can try it by installing the module and calling it like this:
git clone http://github.com/mkottman/acpi_call.git
cd acpi_call
make
sudo insmod acpi_call.ko
./test_off.sh

Anyone tried it on ubuntu 10.04, i'll have my Acer timeline 4810TG next week, and it look's like alot of tweeking to get the battery time

I'd also like to hear the current status of this model. Does everything work out of the box?

Negative, I just got my 4810TG (with ATI) and some things do not work out of the box (installed lucid):
- Suspend to Disk (Suspend to RAM worked for me)
- Reenable Touchpad after disable
- Graphic card switching (I disabled the ATI card with the kernel module mentioned above, it's still visible in lspci, but energy consumption in powertop looks better.)

See http://help.ubuntu.com/community/AspireTimeline/Fixes for some fixes.

Hm, I have the same configuration, but everything has worked out of the box. Suspend and touchpad is fine, and I use ATI (that's why I bought with ATI). I can use the it up to 6 hours from battery.
