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?
# # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # .....
Every time update-grub run all these are put back. Editing grub.cfg does not help.
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'm running ubuntu on a macbook5,4, and I get a 30-second long pause during the boot sequence. (I have quiet turned off.) This shows up in dmesg as:

Details: Linux jagadai 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux Grub. Dual boot with OS X 10.6.4 using rEFIt. It shouldn't be at all relevant, but I'm using E17 on top of kdm.
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.
I have a 5,2 macbook pro, and I use refit to boot my ubuntu partition. I do not have an OSX partition on the local drive at all. The only partitions that are on the drive are the EFI, ubuntu and swap. Refit lives on the EFI dos partition.I am experiencing a very long delay on power-on before the system will load refit (probably 20-30 seconds) Once it loads everything is normal.
I'm trying to track down a longggg delay during OpenSUSE 11.2 boot. It's 1 to 2 minutes long.
1. I upgraded the kernel to "vmlinux-2.6.31.12-0.1-desktop.gz" a while back, and I'm "kind of" thinking this is when it began. It seems in previous versions (I came from 10.3) that the grub menu always contained the previous version. That doesn't seem to be true in 11.2. Is there any way to tell OpenSUSE YaST/zypper to keep the previous version and leave the entry in grub?
2. What does this message mean: "BIOS EDD facility v0.16 2004-Jun-25, 2 devices found"?
I haven't pinpointed the error, and there is nothing really obvious in /var/log/messages. The drives are there, and the network is up. I'm sort of leaning towards the new kernel. What processes wait 60 seconds? If I watch the console closely for the message before the delay, it can vary.
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...
I am brand new to Ubuntu and I am trying to find out if its possible. When the laptop starts it gives me 30secs to choose windows or ubuntu? Is there anyway to change the order or the timer?
I need to do a NFS mount after my PC boot up. So I put an entry in root's cron to do it:
@reboot /bin/mount sun:/mynfs /mnt/sun/mynfs
The mount occasionally fails. But when I manually mount after booting, it always succeed. So I suspect maybe the cron sometimes got executed before the network was started?
Is there a way to delay the mount until after the boot sequence finishes? You know, other than put the command in a script and add a sleep in front of it?
Every time I boot up OpenSUSE 11.3 it hangs at the same "position" for approximately 3 minutes and then continues to boot. Unfortunately I see no corresponding error log e.g. in dmesg output. Hence, I don't know what is the reason for that. Here is my dmesg output. The delay occurs at 20 seconds after beginning of boot process (line 1085). I also analyzed the boot process with bootchart. My computer: Notebook Lenovo ThinkPad R400.
I installed 11.04 after Windows 7. when the GRUB boot menu starts up there is an option for Win 7 boot but it will not boot windows. When that option is selected the screen changes colour for 2 seconds and then reverts to the GRUB menu. Ubuntu boots fine.I downloaded the Boot Info Script and ran it, the results are

I have a netbook and one of the suggested optimizations was to reduce the use of swap.I've noticed on my desktop and conventional laptop that it is quite usual for the swap file to be used even when memory usage is low (25% of available memory).I'm looking for some advise on the best way to set up a conventional desktop or laptop as my understanding is that the use of a swap file will slow the system responsiveness down. Can I use a version of the above to improve performance and reduce swap usage?
I have F8 system that I have installed a fair amount of software on. When I started to install F10 I discovered that the file system is LVM (F8 default) which takes the entire disk (80G). I want to keep the F8 install but add F10 so I can migrate things to F10. So I need to:
1. Back up the system to USB HD so I can restore if things go wrong. Prefer to backup to a non-LVM partition (if that's reasonable). I don't really have any critical data but want to preserve the software installs and configurations that I have spent a lot of time sorting out. 2. Reduce the LVM partition to 20 G to make room for F10 and leave some unallocated space - say 30G for F10 and 30G unalocated. 3. Install F10 (on non-LVM partition) and keep both bootable. I have heard this may involve editing some grub files.
I have used SystemRescueCD a little and want to be able to use it on the F10 partition.
I have installed Fedora 15 on my laptop a couple of days ago, but now i want to install windows next to it.To do this i have to resize the lvm partition.But at the final step (vgreduce) i get this message:Physical volume "/dev/sda2" still in use.What now? Can someone help me reducing the size of my lvm partition?
I have an install of Fedora 12 and I would like to know how to reduce the size of the /var/log/messages file.You see that file is already 120MB large and about 4 days old.I would like to be able to either make a new file daily or adjust a maximum size
There is one directory in /oracle partition in test server which i use to delete that dir after copying in the same location with diff file/dir name. Like this i did so many times.evrytime i m deleting but the /oracle partition space is reducing by 1.5 or 2gb after deleting dirs of 80gb.Directory size is 80GB and partition size 400GB.plz let me knw with steps, is it requires to do De-fragmentation?
I run Fedora FC13-x64. Recently I added a few TB's of RAID5 storage tto my server and moved most data from the root filesystem to that. Now my root volume is way too big. My basic install resulted in a 1TB LVM volume group entirely dedicated to a single lv_root.
Now I want to make room and eventually clone this disk to a much smaller root disk. I see many threads about reducing the size of an LVM logical volume. My first steps were succesful. I used lvreduce and resize2fs to reduce the size of the logical volume and filesystem. I also user pvreduce to reduce the size of the physical volume group.
But still gparted and fdisk report the physicalk volume (/dev/sde2) as 900GB. The embedded LVM stuff is as small as 60GB. Anyway LVM manager and GParted doe not allow me to shrink /dev/sdf2 to snuggly fit the LVM stuff in it.
Ok chaps, what do I need similar to Irfan View on T'other OS (hiss) to edit the Size of Photo's, friends tend to get miffed if I email 5MB Pic's. Loads of viewers etc on Ubuntu, like Playing Hopscotch in a Minefield, can give you a really Crap Day!
I'm wondering if there is a way to shrink an ext3 LV mount as / .I tried to with resize2fs ... but seems that isn't possible if the partition is mounted.
I have a Dell Precision M6400 laptop with an Intel Core2 Duo 2.8 GHz processor.I have set Power Management to performance when on AC power and have also written a script that calls cpufreq-set to set the lower and upper limits to 2.80 GHz (cpufreq-info output below).However, sometimes when doing some heavy work the frequency suddenly gets reduced to 1.60 GHz on both cores and I cannot set them back to 2.80 GHz using the script (cpufreq-set says errors occurred). Performance is then totally gone and I have to reboot. The same script then works fine after a reboot.What is setting the lower limit back down to 1.60 GHz even though I set it to 2.80 GHz using my script? How can I stop/configure this or prevent it from happening?
Alternate Heading: Unable to use opensuse partitioner to fully format a Seagate 1Tb drive OK. Swapped over a motherboard to increase the number of slots available for hard drives so that I could expand my raid array (4 X 1Tb drives). Discovered I had no thermal paste so all delayed for 24 hours while I bought some, miscalculated on rebuild and had to reinstall OpenSuse but in the end system is now up and running. Unfortunately when I formatted my new 1Tb drive (Seagate) it formats to 931.50 Gb while the other 4 drives formatted to 931.51 Gb (they are WD). I'm now in the position that when I try to add this new drive I get :
mdadm: /dev/sdc1 not large enough to join array
Is there any way I can resize the existing devices down to 931.50 Gb so that I can add in the new drive without having to restore the array?
I have Centos 5. I enabled the EL repos so I could upgrade the php to the latest, and now there are upgrades that yum is not letting me get. I have a Virtualmin VPN plugin that needs Virtualmin to be updated to 5.10, but it seems when I updated PHP with the EL repos Yum is now reducing my available packages. Here are some outputs. with some things removed for length.
I've spent hours trying to scan + shrink a multipage PDF documentlosing readability. This is the first time I've ever needed to do this! (I had to scan each page as ".jpg" in order to email and open on another computer, so I could not scan to PDF directly, which I think is why each page was so large; lower DPIs made the text too blurry.)I found this great tip on UbuntuGeek...but anyone can do this if GhostScript is installed:
Have just installed 9.10, again, many failed attempts previously.Cannot get to boot up and show menu on dual boot with Vista initially,However when I delete the grubenv file the system boots ok and works fine.But does not show the grub menu to choose boot up choices.Got the information to delete the file on some posts elsewhere about booting problem, and tried a longshot and got into Ubuntu for the first time from trying to install now for 3 months!The problem is the file grubenv is created each time so on subsequent boot ups the sytem fails to boot again.The Grub version is 1.97 beta 4, most up to date for Karmic I think, I have seen a version 1.98 but dont think its for Karmic?
Is there a way to modify the grub.cfg file to stop this problem ( all posts say dont touch this file??Or install a script to delete the grubenv file on shutdown as a workaround for me, (I have no idea how to do this whatsoever, I'm not familiar with linux at all)I did read that this problem was fixed/patched in Grub version 2, but dosn't seem.so on my system afetr I updated it when I got into Ubuntu.I couldnt find the patch or fix, I got the information I am on about from this post:URL...It seems to say it was fixed or patched by Colin Watson reading through, but I don't really understand whats being said or how to get the patch on my system if indeed there is one?Sorry for being a bit thick about all this, its a bit beyond my brain now, hope somebody can help out as I have enjoyed my brief bit of fun in Ubuntu.
I am trying to streamline my boot screen/GRUB Menu. I know what I want it to look like (grub_wanted.jpg), and I think I know how to get it by uninstalling a couple of things, (synaptic.jpg). Now I have too many items on the screen, and it looks cluttered to me (grub.jpg).
I've installed Ubuntu on my new desktop alongside Windows 7 (each OS is on a separate drive), I seem to have run into a small problem. Let me start with what I did:
- Unplugged 1TB drive from the PSU, BIOS was not seeing my formatted (and thus empty) 500GB drive and I couldn't put it into the boot order at all with the 1TB turned on.
- Loaded up the boot CD and was able to install Ubuntu 10.1 on my 500GB drive.
- Did a bit of configuring, shut my PC off and plugged my 1TB (with Windows 7) drive back in. I tried to see if I could now see my Ubuntu drive in BIOS but nothing is there - just the Windows drive is in the list of available drives to boot from (along with DVD-ROM and USB).
This is where I've run into my problem. What I want is to have a nice GRUB boot menu at the start like any other dual-boot system but just have the two operating systems on separate drives altogether.I did it this way because I was having issues with the advanced partition menu on the boot CD so just went ahead and followed the KISS method by unplugging the Windows drive.
I was told by a friend that if I put my Ubuntu drive into the first position in my boot order and the Windows drive in the second, then I could boot into Ubuntu and run a GRUB update command (he told me to google it) and that would create the necessary GRUB that had the entries for Windows 7 and Ubuntu.Both operating systems are 64-bit, I imagine that might make a difference in whatever help you guys can offer me. I love the hell out of both OS's and want to be able to use them interchangeably.
