wait time after grub selection

[kapil]

In grub menu, after selecting kubuntu.. screen goes blank. a cursor starts blinking on left upper corner for around 15 seconds and then the playmouth boot screen comes.. after that within seconds i come to the log in screen.

i was excited to know before launch of lynx.. that i would take about 10 seconds to boot up. but here it takes 15 seconds just to come to playmouth screen. i switched off the graphical playmouth display. still takes the same time to start booting up process.

What exactly is it doing while flashing the cursor.. is it waiting for some input. and what should i do to make it stop.

(system specs are in my signature)

You aren't seeing anything unusual. "that it would take about 10 seconds to boot up." is likely/probably an exaggeration. From the time I'm presented with the Grub menu and I make a selection as to which kernel I want to boot, the KDM login screen appears in (IIRC) under 30 seconds. From KDM login to desktop takes about another 15 seconds. In all, from Grub to active desktop (for me) takes less than a minute. That is faster than previous versions of Kubuntu.

Tools

bootchart:

Description: boot sequence auditing
bootchart allows you to audit the boot sequence of your computer and
generate a pretty chart of the processes run, including how long they
took and how much CPU and I/O they used.
.
The auditing is performed by a tool that runs in your initramfs, or
early in your boot sequence, and records system statistics as your
computer boots.
.
Tarballs of this data are left in /var/log/bootchart; from these either
PNG or SVG will be generated if pybootchartgui is installed.

pybootchartgui is a tool for visualization and analysis of the GNU/Linux

Re: wait time after grub selection

hmm..
@snowhog: exactly. under 10 seconds was exaggeration. i wonder if ubuntu loads faster than kubuntu. at least on some of the forums ppl say ubuntu loads in 10 second. on my laptop.. kubuntu and windows 7 takes same time to come to login screen. win7 takes few seconds more from log in to desktop. (but considering that i have disabled the windows updates since i used it first time..less boot time is not surprising..and yeah.. it is pirated win7 )

@Rog131: thanks..
i will try that when i get free time.
