Ok, I finally had time to fix more issues on my Timeline 4810T SU3500. For people having issues with Suspend, Hibernate, Brightness, and ACPI. The solution has already been posted here before so I'll just echo this back:
First download the 2.6.30 kernel packages from the kernel PPA:
Code:
#$ wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630-generic_2.6.30-020630_i386.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630_2.6.30-020630_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-image-2.6.30-020630-generic_2.6.30-020630_i386.deb
Code:
#$ sudo dpkg -i linux-headers-2.6.30-020630-generic_2.6.30-020630_i386.deb linux-headers-2.6.30-020630_2.6.30-020630_all.deb linux-image-2.6.30-020630-generic_2.6.30-020630_i386.deb
Reboot and you might notice that you lost your sound. To fix it, we have to build the ALSA module for our newly installed kernel:
Code:
#$ sudo apt-get install build-essential linux-headers-$(uname -r)
Download and Extract ftp://ftp.alsa-project.org/pub/drive...1.0.20.tar.bz2
Code:
#$ cd alsa-driver-1.0.20/
#$ ./configure --with-cards=all
#$ make
#$ sudo make install
Reboot and you'll find that the sound is either muted or in a very low volume (same case with mic). To fix this tinker your settings using "alsamixer":
After that you will have a fully working Ubuntu on your Acer Timeline. ACPI works properly and you'll immediately notice a performance increase on video (try setting the Visual Effects to Extra). AHCI mode also works! Keep in mind that you might have to recompile and install ALSA again when you upgrade to a new kernel (Unless Ubuntu releases their own 2.6.30 generic kernel in the repositories). Also there's a quick way to check if your webcam is working:
Code:
#$ gst-launch-0.10 v4l2src ! xvimagesink
Cheers!
EDIT: For those who experienced some network disconnection issues with kernel 2.6.28 (when copying large files within a local network), 2.6.30 seems to resolve the problem.
