    I updated from 9.10 on my gma4500mhd powered laptop, yet I see no plymouth, in fact the whole boot process looks like a mess with debug/error(though harmless) messages. What's plymouth supposed to look like on ubuntu with KMS?

        That looks like side effect of the upgrade from 9.10 to 10.04.

          While it's good you have the full bootchart images for completeness, a simple graph plotting distro vs. time (s) would be appreciated as an excutive summary

            Keep in mind the focus for the 10 second goal on netbooks was changed to apply to a UNE session boot not a full gnome session as far as I am aware. Although gnome did benefit a lot from the speed boosts, it does have a few things slowing it down that aren't in UNE like compiz (UNE uses mutter).

            There are some charts here for a full gnome session on a dell mini 10v though that may be interesting

            uwgandalf: There are some problems you could be hitting if you have a custom fstab holding up plymouth from loading until really late since they decided not to put it in the initrd for everyone unless they have cryptsetup installed. Running these two commands from a terminal should make it much nicer looking though, I recommend everyone using KMS on lucid to do it

            echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
            sudo update-initramfs -u

            to revert it just sudo rm /etc/initramfs-tools/conf.d/splash and sudo update-initramfs -u.

                standardized procedure...

                >After installing Ubuntu i386 to each netbook (except for the x86_64 edition with the ASUS 1201N.
                You are meant to compare the devices in EQUAL conditions!
                It might not have had a huge effect on the boot time, but still, I consider this as bad manners and something that you should be more careful with in future tests. I understand that phoronix is place of numbers, benchmarks and comparison charts, but if you want to keep it like that, at least FOLLOW THE PROCEDURE!

                Also, is it that difficult make a little bar chart comparing boot time in addition to bootchart output? You know, it is not very netbook friendly if you just want to get the general idea and instead of having a quick look at the bar chart I have to click on the bootchart output and scroll around.

                  I didn't measure the time. But my Netbook boots "fast enough". It may be more than 10s but not much.

                  On my desktop it's also very fast. In fact POST takes much longer than to get to the login screen of both Windows 7 or Ubuntu 9.10.

                    That is probably because you have AHCI activated in BIOS which slow things down on some motherboards (e.g. my ASUS P5B). It takes me ~30s to get until grub and only ~17s to get to gdm.

                      This makes Plymouth work as it should! Thanks Sarvatt!
