I have a mental block whenever I'm confronted with anything to do with grub2. Changing things in menu.lst was SO much simpler....
I want to include the command 'acpi=off' - but where do I put it? Can I change the detail of an existing grub entry in this way, or do I have to create a complete custom menu entry in grub.d and include it in that?
I have installed grub2 on a flash drive to boot some os's that I want to carry around. But in grub.cfg when i put this:
Code: menuentry "BackTrack Persistent" {
set gfxpayload=1024x768
linux/backtrack/boot/vmlinuz BOOT=casper boot=casper persistent rw quiet
initrd/backtrack/boot/initrd.gz
} it does exactaly the same thing as this

I'm thinking of filing a bug report but I want to make sure i'm not doing something wrong first.
How to remove OS's from the GRUB boot menu, and also, how can I change the default booter from Ubuntu to a different OS and edit timeout?
View 2 Replies View RelatedMy grub2 boot entries never change. I have run sudo update-grub and it finds all the proper kernels and such and says that it has updated. I check with the menu.lst and grub.cfg and they both look to be correct
View 13 Replies View RelatedI've just got a question about this. What if you wanted to change only the display sequence in Grub 2 (Ubuntu 9.10) and not which o/s boots first or is the deault o/s? In previous versions of grub you could just copy & paste the lines in /boot/grub/menu.lst, but this version of grub doesn't allow you to edit /boot/grub/grub.cfg...

View 1 Replies View Relatedi've started off using linux with ubuntu 10.10, and then i moved to linux mint 10 kde, and after finding out that it didn't support my hardware, in specifically my graphics card, i switched back to ubuntu 10.10, and from there i upgraded to 11.04. i hated the gui so i switched it from ubuntu to ubuntu (classic) environment. i also installed kubuntu-desktop too, and it looks a lot like mint 10 kde, i guess it uses kde 4.6, but... it's more stable for me. anyway, what i mean is that, originally ubuntu had a black background, linux mint 10 kde had a pretty cool custom mint background, ubuntu 11.04 has a purple background. i looked on videos, i found people using customized backgrounds, but they either don't explain how they got it *like for instance, someone said opensuse 11 or 13 has an icy penguin animated background, and someone else had one that you could scroll through.* or it's too complicated or outdated. is there a simple way to change your grub2 boot loader background image?

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

View 6 Replies View RelatedMy question is about TCP parameters in Linux. By now, I want to change the default values of:
Initial Timeout
ACK Delay
Idle Connection Timeout
I have a Linux Box with kernel 2.6.x and 2 ethernet interfaces. I know TCP is a stack that doesn't have anything to do with ethernet devices. Said that, the question: is there a way to set custom values for each interface? For example, a server listening to connections in eth0 would use one value for Idle Connection Timeout and another server listening to connections in eth1 could use a different value for that parameter.

Ubuntu 10.04 Gnome IBM Thinkpad 600e.I am trying to get sound going in my 600e which has the wrong chips in the sound card. I found some notes from 2008 that said in one of the steps to add the following to my kernel boot parameters: noapci nolapci notsc acpi=off pnpbios=off pci=noacpi
It said to hit the Esc key when I see the Grub Count on boot up to get into the kernel boot parameter's editor. However, I am not seeing any Grub Count and pressing the Esc key every second during boot up doesn't seem to get me there either. I have been searching for how to edit the boot parameters but no luck so far.
My keyboard doesn't work after the bootloader.
I've read that I need to add "i8042.nopnp=1 i8042.dumbkbd=1" to the boot options.
I have a 10.10 factory disk.
Old Toshiba laptop model A30 -- tried various installs 8.04/9.04/9.10. They all hung trying to boot the install disks after the initial few screens. Finally, I got 9.10 to install, dual booting XP and 9.10 by choosing F6 from the initial menu, and putting an X beside:
ACPI=off
noapic
nolapc
edd=on
nodmaid
and then hitting escape.But, after the install, I couldn't boot 9.10 from grub as it hangs after about 30 seconds of trying. The live CD would not work without the above parameters being set as described above, but does work with them set! I need those same parameters passed to grub at 9.10 boot time, but I can't figure out how to do that. I've had many successful installs of Ubuntu across a number of desktops and laptops, but I never had to deal with the guts of grub before. It all just worked.
I installed Debian 6 last night on an older Compaq. For the system to properly reboot and shutdown when requested, both acpi=force and reboot=warm must be in the boot parameters, this was required with other Linux distros installed on this hardware. Otherwise, the system erroneously shuts down when reboot is chosen.
I would like to know how to permanently add these so they pass each time the system is turned on.
I already added these to /etc/default/grub (and ran update-grub afterwards) and at the next startup, noticed they were NOT in the parameters when "e" was pressed at the boot menu.
I'm making some tests with Debian Setup.
As reported by the docs [URL] .... there are some boot parameters available for the Debian Installer.
I would like to try a setup setting the base-installer/install-recommends to false.
This can be done via preseeding, but I'd like to try it out setting the boot parameter.
I've tried several combinations but no one has been effective.
What is the syntax for setting the base-installer/install-recommends parameter to false at boot time?
I've installed opensuse 11.4 by doing a network install, (boot off kernel + initrd, everything else is fetched off network) and i skipped the bootloader part because i've already got two other linux systems set up with grub2 on my computer. I picked the minimal server install (text mode) and didn't make any other software selectiono changes.
My partition layout is as follows
ssd drive contains / partitions for distributions (GPT layout) hdd drive contains encrypted lvm PV (PV on a luks partition). inside that PV is a VG with volumes for /home and /var (and other), where each distribution has its own /var.
The problem is that i cannot get initrd to open the luks properly. i tried chrooting, rebuilding the image with mkinitrd -f "lvm2 luks" ( i saw that somewhere on opensuse wiki, i think ) and adding boot parameters like this : lvm_box=/dev/disk/by-uuid/<luks partiiton UUID> lvm="box" (where box is the name of the lvm array).

I have a generic monitor which has problems with many Linux distros. We can boos Sugar on a Stick v2 by pressing <tab> at the Sugar splash screen and adding the boot parameter "nomodeset". I'm handy enough to do this, but my wife, well, not so much. So is there a way to make that boot parameter permanent?
View 1 Replies View RelatedI own an HP Envy 14 [url]. Letting Ubuntu (or any Linux) attempt to boot into a Live CD without changing any parameters results in a black screen, but with everything else working (for Ubuntu, that means the login sound is played). I've discovered that putting nomodeset in the kernel line will allow me to get so far as a command line, but I can't startx from here (I get "Screen(s) found, but none have a usable configuration."). I think my issues have something to do with the dual/switchable graphics in my laptop.
View 7 Replies View RelatedAccording to the man page, the "recent" match of iptables accepts certain parameters (e.g. "ip_list_tot"). I'd like to change the values of some of them.
All the solutions found on the web were about changing parameters for module, but my kernel was compiled without modules support (such that it can be used for installation booting as well).
How can I change the match parameters for my non-modular kernel ?
How do i find out the exact kernel parameters (from the grub config file) when the boot loader is corrupt. Seems like a catch 22 that I need the exact boot parameters when I cant get to a prompt to read the grub.conf file to being with.

I was wondering if it was possible to make it such that the default is the last booted system?

I may not be around during the 10 seconds before it boots into Ubuntu.
View 1 Replies View RelatedI recently got a netbook and setup as dual boot between win7 starter and 9.10 (64bit). Win 7 starter is not impressive so i want to nuke it and give the space all to my /USR partion. I am comfortable working with Gparted and assume that i can launch using my gparted live usb and delete the windows partion and then resize the /usr partion.
what changes do i need to make w/ Grub2? I would prefer not to see the Grub menu at all and have it load right the main kernel if possible. Also, if this is possible is there a way to get to the Grub menu during boot should i need to select a different kernel?
After installing karmic with Grub2 I am unable to boot into Archlinux partition. Grub2 has removed the last line of the Archlinux boot stanza! It used to read:-

But no luck. Only way into Archlinux is to get into the edit shell and manually add the missing line and remove other stuff not needed. I have spent hours trying to resolve this issue and I am fairly p----d off
