Ubuntu Installation :: Post-GRUB 2 Delay - Troubleshoot This And Determine What Is Causing The Delay
May 11, 2011
After GRUB 2 comes up (I'm running Ubuntu 10.10) and I choose the OS to boot, there is about a 5 second delay where nothing appears to happen after I make the selection -- no disk activity. It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?

I have GRUB "1.98-1ubuntu6", and while I have been using GRUB, I have always wondered how to change the delay time prior to GRUB booting into the default operating system. I would even like to switch it off, if possible. Thanks for any help you may have, as I can't seem to find mention of it anywhere, and I think a 10-second wait is silly, having been accustomed to adjusting LILO to any delay time I liked.

I want to install my system on my U-Disk.So I need to delay the time when system starting before the system recognized the U-Disk. How to change it in the grub? If I change it ,how can I save it in order not to change it every time I start the computer? Is it in the /boot/grub/menu.lst?

This morning I had the courage to run an apt-get autoremove which took some 275 packages off my hard drive, and now I am experiencing a delay of about 40 seconds at boot, after grub, before the plymouth splash appears. The cursor blinks on a black screen while the hard drive churns away. Finally two error messages appear too quickly to be read, and then the bootsplash kicks in. I can find the instant in the dmesg where the delay happens, but can't locate the cause. Here's what my dmesg looks like:
[Code]....
The laptop is an Acer Timeline X 3820TG, with the dual GPU "switchable graphics." These dual graphics cards have given me enough trouble in the past that I wouldn't be surprised if they were the problem. But the hard drive action sounds like a 'fsck,' and seems to be contemporaneous with the dmesg notice that the root partition is mounted.
Incidentally, my boot wasn't all that fast before; I would not be surprised if this delay was preexisting, but used to happen after the plymouth boot screen was already on screen. Still, if I can get rid of this one ugly delay, I can have a fast (c. 10 secs) boot time.

Right after I type in my username and password and hear the usual login sound I have to wait about 15 to 20 seconds to get the X desktop. The system load average monitor is at its max and starts to become lower.If I log out and in again I dont get that delay. It only happens with logging in after a reboot/power on.I tried to open a console (Ctrl+Alt+F1) before I log in, move back to X and login then jump to console and use htop to see what's eating up my resources during that time with no luck. Everything seems to be normal.

I have a Macbook 5,2, on which I'm triple booting OS X - Linux - Windows, using bootcamp and rEFIt.I had a variation of Ubuntu 10.04 called Uber Student as the linux installation.I installed Ubuntu 11.04 AMD64 instead, by choosing the EFI boot option.Now this gave me some problems. When I shot down, the Macbook gives me a troubling long beep sound.When I start up, I'm still able to boot up into rEFIt and Grub2, but there is a big delay with the screen being black for about 30 seconds and the little white light in the left corner of the Macbook is blinking feverishly. I read something about a guy which had a similar problem and the process seemed to mess up the firmware on his Macbook, so he had to have his MB changed.
What's up with the scary beep sound and the long boot up delay?Secondly, when I want to do an update of the Ubuntu system, the update manager asks me to do a partial upgrade, which includes removing the grub-EFI, resulting in a system that won't boot...

H/W : Intel 1.6GHz, BioStar U8548
S/W : Ubuntu 8.04 + RTAI + EMC2 (CNC controller)
In configuring CNC controller system, latency-test must be run to find maximum jitter of the system. It counts about 17,000 ns for few minutes, then it suddenly rise to 260,000 ns. It is impossible to control CNC with such large jitter.
In tracing this problem, I found that Award BIOS setting "Delay Prior to Thermal" is firmly engaged in making a problem. When I set this setting to 4 minutes, it makes large jitter periodically with exact 4min 15sec period. When I changed this setting to 8 minutes, its jitter is 8min 15sec period.
But, there is no option to disable this BIOS setting.
I heard that ACPI enabled OS can take over the ACPI function of the BIOS (which may include this "thermal" setting), but RTAI tuned kernel don't include ACPI modules.
Is there any solution to this problem ? If I recompile kernel with RTAI with ACPI processor module enabled, would it be a another problem maker ?

I am trying to set up sshdfilter on my new linux box and can't get the expected functionality. I couldn't get IP's to be blocked no matter how many bad passwords I put in. I have sshdfilter set up to read from a fifo (/var/log/sshd.fifo, which has been chmod'd to 600), but when I run sudo tail -f /var/log/sshd.fifo, I don't see any output as I attempt to SSH into the machine, though /var/log/auth.log is correctly logging the login attempts. However, when I run sudo reboot -h now, the entries from /var/log/auth.log appear in the FIFO. I'm wondering if I don't have a misconfiguration somewhere that isn't allowing my auth.log to pipe to my FIFO (I am running a virtual bridge). I can provide more system specific information if anybody is curious (no, I won't give you my IP so you can brute force my sshdfilter-less computer.

I use the Gnome Mail Notification Applet and have recently moved from a wired desktop machine to a wireless laptop.
The problem I have is that the Mail Notification shows an error because it tries to check mail immediately, the network hasn't finished connecting at this time though.
Is there a way to add a delay to this? I can't see one.
Or if anyone can suggest an alternative that is just as good (or better) and allows for a delay?

Using 64bit 10.10, when I click any of the controls that manipulate sound, such as pause, play, or changing volume, there is a 2 second delay before it takes effects, some examples:
- If I hit Play, then the video will begin to play but I hear no audio for 2 seconds, then the sound will begin in sync.
- If I adjust the volume it takes 2 seconds for it to actually change.
- If I hit pause it will immediately pause the video portion, but the sound continues for an additional 2 seconds before stopping.
I have seen numerous people on Google with my problem by googling "flash delay ubuntu". I do not believe this is related to pulseaudio, etc. that I know of, but seems to only occur using Flash as far as I am aware.

I've been experiencing a weird delay between me pressing the printscreen key and the screenshot dialog appearing. The delay is about one second, and is happening even though gnome-screenshot's delay key is set to zero in gconf-editor. This delay is making it difficult to capture things which disappear quickly, and I'd like to know if there's any way to make the screenshot dialog appear instantly.

I am using Ubuntu marvic amd64 10.10. I installed ns-allinone 2.34. then I inserted vbr traffic according to one of forum from this linux " Insertion steps of VBR into NS2.34" I made the following changes
Makefile, line 36 : CC = gcc-4.3
Makefile, line 37 : CPP = g++-4.3
vbr_traffic.cc in ns2.34/tools then Makefile : tools/vbr_traffic.o of 183
then I use the command cd ns-allinone-2.34/ns-2.34/ && mv ns ns234 && make after that I delete the ns. with the new command I run the script with every time puase time 0 and simulation time 200, 10 250, 20 300, 40 400..... with DSR after completion of simulation, when i was try to plot graph between throughputs of receiving bits vs Maximul end to end delay, every time I got the delay more than 90, 100, etc so how can I reduce that problem. I thought problem was in insertion of vbr.

highlight text, go to where I want to paste it, click middle mouse button. The text then appears after a delay of at least a second, sometimes several. In SW13.1 and previous, the pasting was almost instantaneous. How do I get rid of this delay?

I'm having a problem with GDM very similar to the one described in the thread below, though they did not find a solution.
[URL]
Basically when I boot the machine I first see the terminal login, then after a moment I get what looks like some graphical corruption followed by GDM appearing.
I've already attempted reinstalling GNOME and X, then manually reinstalling GDM, but none have solved the problem. I'm currently in the process of enabling boot logging as described in the thread, so I'll post that soon.

Problem started after installing a new firewall in my network. originally after installing the firewall there would be a 10 second delay after entering a command before it was processed, the command would be executed however there would be an error, i forget what it said, something about not being able to resolve my domain name (and it would give my domain name). i realized this was a problem with my NAT, so i configured DNS forwarding on my firewall so that any attempt to access my server using my domain name from inside the network would point back at my server. after setting up the DNS forwarding i no longer receive the error about my domain name being unreachable, however there is approximately a 30s delay between entering a command and its execution.
the problem is hardly critical i do not see any more serious problems, it is just a pain to do any work when every time i try to do something i have to wait for it to execute.

get the delay from booting into gnome to actually getting up your desktop? Mine seems to boot, come to a purple background with a pointer, then after a while of waiting the panels and my actual background loads. Just wandering if anyone else gets the same. Edit > Happens regardless of what drivers i use for graphics so it's not an issue of open/closed drivers.

I use to auto start Firefox and Thunderbird. I would like to add others but using a delay. For instance, Firefox starts with 10 seconds of delay, Thunderbird with 30 second an so on. I tried to make a script using "sleep" command, but I am not expert and nothing worked. So, do you know if already exist an application that does this if not, are you able to show me how to create the script?

When I log into my ubuntu 10.04 after booting my computer, I receive a 30-40 second lag before I can actually log in. During this lag, I can move the cursor and the login background is shown, but the computer seems to be doing nothing. It is as if there is a sleep command before I even log in. I am using a Sager 2096 computer but I got this computer for free and it did not come with the specs. I had installed a 64-bit version of Ubuntu because this computer has a 64-bit architecture. However, whenever I install software, it always has to install the x86 version because the x64 is "not supported." Perhaps I have a mix of 32 and 64 bit programs and that is what is screwing it up?

I am running 10.04.1 and despite everything I have tried I cannot suss out why my machine is so slow. It runs fine in the other OS installed but in Ubuntu there is a lag to every action, eg if I drag a window it follows about 3 seconds later. Basically everything is delayed for some reason. It is becoming very annoying and I am contemplating a reinstall, could someone please prevent this. The system is running on an old Athlon 2800 and I have attached a screenshot of running processes.

In Ubuntu 8.04, when I wanted to reduce the boot menu delay I had to do the following:
enter in terminal: gksu gedit /boot/grub/menu.lst
I then looked for the line that begins with timeout and changed the value (shortened the delay)
Now with ubuntu 10.10, when I tried this I do get into the Gedit text editor as with 8.04 but it is completely blank, no entries at all? So nothing to change! So how do I change the boot menu delay in ubuntu 10.10?

I have it set up to start my music player (RBox) and torrent program (Transmission) when I log in. The problem is all my data is set on my 1TB external hard drive, because my internal hard drive only has 80GBs of space. When I start up the programs open but the external hasn't had time to link the file directories which messes screws up my torrents into having to verify every time and my music has to "recalibrate" as it were.
This isn't an issue when I manually open the programs after a minute or so but what my question really comes down to is... Is there a way to delay an automatic startup? Say, run application 3 minutes into boot up?

I'm running Natty with Unity 3D. I had a long black screen with no Plymouth Ubuntu logo boot. After the black screen, Natty loaded straight into desktop.
Then I installed this [url] Which now gives my Grub2, about 10 seconds of black screen, Plymouth Ubuntu Text boot and then desktop.
Any way to remove that long delay?

I'm getting this weird noise and (sometimes) delayed audio on HDMI out on VLC. I've tried banshee, miro, ..... on FF and all of them work just right. I would settle changing VLC's sound output to ALSA, but it's also buggy as I get no audio after pausing. Restarting or reloading Pulseaudio and ALSA didn't work either.
Does anybody have a recommendation? Obviously, I'd like to stick with VLC.

Last Saturday, I ran an update on my laptop using F12 and received a new kernel. As of this morning, the new kernel hasn't shown up on my desktop, using f 11. (Yes, I check every day.) Currently, my uptime is 34 days, so you can see how long it's been since the last kernel update for F11. Does anybody know why there'd be an update for one version and not for another? In case anybody's wondering:
