I've been by the site just this morning and am excited by the idea. Such a niche distro might be difficult to maintain with such a small group of users. Be sure to stop by and take a look at the site, sign up and show some support. I will certainly be putting forth some effort from all the lessons learned in this blog.

That being said, I intend to pull down the vanilla 2.6.37 stable source (www.kernel.org) and build a kernel from that. If it works, I'll build a tutorial that will offer up how to build the kernel, at least the options required in the kernel, and then how to setup the hardware acceleration. Unless of course Canonical pushes an updated kernel before I can knock this out. Maybe I'll figure out how to run my own ppa and make it really easy for those uninterested in taking the time to build the kernel.

While the switchable graphics tutorial from a couple of days ago will get you up and running nicely on the integrated graphics, it will not get you anywhere with the hardware acceleration on your discrete card. At least not on the Envy 14 or any other machine that uses the 'Evergreen' series of ATI cards while running Ubuntu 10.10. The issue is that the newer open source driver that has the code to use the discrete graphics cards hardware acceleration isn't supported under the 2.6.35 kernel. Its possible to get the graphics card up and running with hardware acceleration under 2.6.37, but sadly doing so at this point will break the touchpad patch from earlier. I'm currently in work on a fix for this and will be quick to submit the change to the patch and also to put up a tutorial as soon as I can.
It should be noted that updating the kernel to one of the mainline kernels will make it very difficult for you to get support on the Ubuntu forums as you are moving away the standard system. Also while it may fix the graphics, its not uncommon to deal with feature regression even though you are updating the kernel. Its not hard or even impossible to boot off an earlier kernel that is still install on your system. In fact, this is why you are by default given the boot choices in Grub upon boot. Just in case a new version of the kernel breaks your system you are still able to back track.
Tutorial to come soon!
Also feel free to drop off a comment or an email if you have a particular feature or issue you'd like help setting up.

- Brightness = Max 100% (10)
- On Demand CPU performance on = ( echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor)
- Sound card power management enabled = (echo 1 > /sys/module/snd_hda_intel/parameters/power_save)
- File System power saving = ON ( sudo echo 1500 > /proc/sys/vm/dirty_writeback_centisecs)

This is in a separate post to make finding answers easier later.
Problem: Switching between virtual terminals with the typical Ctrl+alt+F1 (or other function key) doesn't work.
Solution: Use Ctrl+Fn+Alt+F1 (or other function key)
Problem: Screen brightness set to 0% at boot
Temporary Fix: use the brightness control on the keyboard. No need to use the Fn key to get the brightness to work, just hit F3 a couple of times while booting. This works with the Live CD as well.
Solution: Enter this into a terminal without the quotations of course -
1) "cd /etc/init.d"
A quick explanation of what this little code does and a warning for the new users! Ensure that you follow the first step! This command will enable you to fix the system if this breaks anything. Simply do a "sudo cp /etc/rc.local.org /etc/rc.local".
The explanation of this code:
sudo = Run code as root
echo -e = output text that follows and execute escape characters
"#!/bin/s...rc.local" = File text that will tell the computer to set the backlight to 30% brightness at start. Change the 3 to a value up to 10 if you'd like it brighter or darker.
Thats all for today. Tomorrow I'll be working on the erratic clickpad.
First my specific model with specs:
HP Envy 14-1111nr
Specifications from Microsoft's Store:
"Display:14.5 in diagonal High Definition HP BrightView Infinity LED (1366 x 768)
Processor: Intel Core i5-460M 2.53 GHz
Memory: 4 GB DDR3
Hard Drive: 640 GB SATA 7200 RPM
Operating System: Windows 7 Home Premium
Optical Drive: Slot-loading SuperMulti 8x DVD±R/RW with double layer support
Media Drive: 2-in-1 integrated digital media reader for Secure Digital cards and MultiMedia cards
Audio: Beats Audio
Video: ATI Mobility Radeon HD 5650 with 1 GB graphics memory
Ports: 3 USB 2.0; HDMI; Headphone output (combo mic in); Microphone input (combo headphone out); eSATA; LAN (RJ-45)
Battery: 8-cell lithium-ion, 59 WHr (6.5 hours)*
Camera: HP TrueVision HD webcam
Dimensions: 14.01 x 9.33 x 1.16 in (355.85 x 236.98 x 29.46 mm)
Weight: 5.2 lbs (2.3 kg)

Model number: 2767774"
The video card is actually a combo. It has the ATI video card for 3D Support and an Intel i915 integrated graphics chip for 2D (Intel Arrandale). This setup is supposed to save battery life by using the less power hungry integrated graphics while the extra power of the 3D card isn't needed. Sadly the Linux kernel doesn't yet smoothly support switching between the two.
So a quick rundown of the issues that I've noticed so far:
1) Synaptics Touchpad (Clickpad) doesn't handle multi-touch
2) Screen brightness set to 0% at boot
3) Ctrl+alt+F1 doesn't switch to a new virtual terminal.
4) Switchable Graphics are not switchable
5) Battery Life is nowhere near the 4ish hours others are getting in Win7
Thats all for now.
