Today's boot time is, again, 1m 9s. Just to add some perspective, Ubuntu boots up in 36s when you use Unity as the desktop shell. Even Unity 2D can't beat that. With Unity 2D as the default desktop shell, I'm getting a 43s boot up.

1m 9s start up. Things are fairly stable nowadays. Hopefully, Ubuntu System Compositor will at least speed things up a little in Ubuntu 12.10.

Ubuntu 12.10 "Quantal Quetzal" should have it's blueprints more or less stable by now. Here's a few things to keep a look out for. Ubuntu System Compositor A new framework(?) that lets the Ubuntu developers control the display from bootloader all the way to desktop. This is a good thing when it finally comes to fruition. In the mean time, I'm expecting my earlier prediction to hold, at least

Boot time is holding steady @ 1m 8s.

I think I'm starting to like Gnome Shell more than Unity. The trade off is I get a boot time of 1m 9s. Pretty big difference here.

Boot time is 34s with Unity desktop. Let's see if it lasts...

Today's boot is 1m 15s. A minor blip in Ubuntu's startup time.

Kernel 3.4 came out with some rather interesting updates: - btrfs performance improvements & better error handling. We're stepping closer to btrfs as the default filesystem. - more GPU drivers. Of course, I'm particularly interested in the Radeon 7xxx & Trinity APU support. - new x32 ABI for 64-bit mode with 32-bit pointers. A nice feature for apps that benefit from 64-bit mode but don't use

Today's boot is 1m 7s. Maybe I should give Unity 2D a go?

Today's boot time is 1m 6s. It's certainly looking as if Gnome Shell has a negative impact on boot times.

Strangely, boot time's gone down since I got me a Radeon HD7750. Coincidence? Boot time is 29s. I hope this keeps up. I'm taking a guess it's because I'm running on gnome-panel since the HD7750 isn't sufficiently supported yet to run Gnome Shell.

Sapphire Radeon HD7750 PCIe card The Radeon HD7750 is currently unsupported on Ubuntu (tried on Ubuntu 12.04) at this time. If you're thinking of getting some hardware accelerated action, forget it. If you happen to be running Windows 8 Consumer Preview, forget it. It's that simple. Plug in a HD7750 and you'll just get dropped to the fallback desktop session with no desktop effects. That's all

A suprising 50s boot time today. Nice!

Gnome Shell loaded but wasn't responding. Weird. Alt+SysRq+REISUB followed by a Ctrl+Alt+Del was needed to reboot the system. After that, things went back to normal. Anyway, boot time today is 1m 11s. Same as yesterday.

Today's boot is 1m 11s. A tad bit better than yesterday.

AMD's processors aren't known for their performance (quite the opposite), but their APUs certainly have a certain allure. A good enough GPU coupled with a good CPU all in one package. I'll certainly want a Trinity-based notebook. Just check out the various reviews on all the major sites. Be it Anandtech, Tom's Hardware, or Techspot the result's the same. It's pretty obvious Trinity won't beat

Boot time: 1m 9s. Maybe getting an SSD would help. But those are outside the budget right now. Too bad.

1m 9s boot time. Yup, looks like it's oscillating.

Today's boot time is 1m 10s. Unless you intend to keep an archive of boot charts, it's a good idea to clear up /var/log/bootchart once in a while. ~$ sudo rm -R /var/log/bootchart/* Simple as that.

So we're back to 1m 9s boot up time.

If you check out the list of blueprints for Quantal Quetzal, you'll notice there's a blueprint for text free boot. This is just another step in the long road Ubuntu has been on for a long time now. You don't have to look far to find a similar blueprint for an earlier Ubuntu version. It's high time we finally reached the goal of a text free boot. It's been a long road. We've used various splash

1m 10s to start up. Looking closely, it seems that bootchart is still counting time even after you've reached the desktop. So you get to see processes like Firefox or Transmission in the bootchart if you tend to run stuff just as soon as the desktop is "ready".

Boot time is back to 1m 9s. Should I be glad? Although boot times don't look as awesome as they could be, the Ubuntu 12.04 desktop running with Gnome Shell 3.4 is snappy. Boot times doesn't mean poor desktop performance. It just means it takes longer than it needs to to get you to a ready state.
