Debian :: Grub Settings Revert After System Update
May 18, 2010
I used the Debian Lenny (main, not testing) update manager yesterday to install some new updates. Took a few minutes and no problems but today I started up and for some reason my system wouldn`t load.The hard drive installer automatically sets hd1,0 as my Debian system when it`s 0,0. I had changed this but upon updating yesterday the system again has grub using the previous setting.
Is there any logical reason why a system update (not upgrade, just small update via update manager using only main files not testing or volatile nor backports) could or would change my grub settings back to the wrong ones? I haven`t installed anything else, the only change has been the standard system update so it can only be that which caused it, but why?

So my computer has ubuntu 9.10 installed 1st and I want to install win 7 in a separate partition. Basically, ubuntu 1st, win 7 later so far from what I learned from search results, grub 2 have problem with win 7 installed later and what was recommended was install win 7 before ubuntu. how ever I do not have the time to start over again because there are too many things to back up or install again. can I simply revert grub 2 to grub 1 again and resolve the problem?

Since I installed the system-wide equalizer I've been having some problems with my sound system. The problem is it has changed some system settings (visible in gconf) and after I uninstall it, I can't change any sound settings, except the volume in a given application, but the system-wide volume doesn't work, even the tray icon shows three dashes next to the little speaker and the sound settings won't start. I'd like to revert the settings to the original after removing the equalizer, as at this moment I can't change any settings even with the equalizer enabled. Is there any way to reset the sound settings
(I suppose it must be in gconf, but I don't know what the values should be. Currently the musicaudiosink settings are: audioresample ! audioamplify amplification=0 ! pulsesinkv)
Those are the settings that definitely changed after installing the equalizer, but they obviously won't change back after uninstalling it.

After much pain I finally got a fairly good install of 10.04 (apparently due to my large disk earlier versions like 9.1 are a no go on my machine a Gateway mx6028 laptop with a new 160 gb drive.) I bricked the machine several times applying the bulk auto updates after the initial install so this last time I applied the updates in smaller batches,, I believe the problem is associated with some of the open GL stuff,, any way to
A) go back one update??
B) anyway to permanently mark an update to never come in?

I just installed Ubuntu 10.10 and I installed and messed around with startupmanager. Now I get status text when I startup, shutdown, and resume from suspend.
I have "show text during boot" disabled. And I tried turning "show boot splash" on.
How can I get the default behaviour?

My GMA500 (poulsbo) driver is not working any more because of the latest update I made using Software Update.
The update was a new kernel:
[omass@omass ~]$ uname -a
Linux omass 2.6.30.10-105.fc11.i586 #1 SMP Thu Dec 24 16:26:26 UTC 2009 i686 i686 i386 GNU/Linux
Now, after this update, when I reboot I get the following error code...

I've had two hd's in my box forever. for more space and backup reasons. Well I have started running the Debian Squeeze distro since December. I've had many issues, some are still unresolved. but now I'm running into major headaches with the fstab. Specifically dealing with/wondering why UUID's are used instead of the old /dev/hd? I was a little annoyed when I tried Kubuntu to find /dev/sd? used instead of /dev/hd? but that was workable. But the UUID's are a nightmare. Here's my problem.
My main box is finally giving up the ghost. The mobo is dying. So in order to do some tests I took my hd bundle (my two hard drives with their cables) physically out of the box and temp installed them in a test box. I wanted to do some benchmark and other tests. I got all kinds of errors. I found that the system wasn't recognizing the UUID's listed in fstab. My concern is when the new mobo gets here next week I won't simply be able to plug the hd's in like I always have been and just let Linux reconfigure itself (Debian used to be good about this). I really don't want to have to clean reinstall if it's not needed.
So for this I have two questions. WHY developers decided to drop using /dev/hd? or even /dev/sd? ?
And is it possible to revert fstab's listings back to the old /dev/hd? settings. In debian fstab had lines commented out showing how each partition was listed in it's /dev/hd? status during install.
I'm getting really sick of all these archane changes in ALL aspects of linux that don't seem to have any good explaination or need.

I have a user who has recently switched to Debian 7 (from Windows). While reinstalling his PC I foolisly went straight to install the ATi proprietry drivers (as every computer I have come across this in this building is running with an ATi card). Once install I found out that the computer actually had on board Intel Haswell graphics. So I installed the correct driver and uninstalled the ATi one. Since then System Settings refuse to open they are forever "Starting". The user is running on Gnome Classic as Gnome 3 refuses to start (in what I am starting to suspect is a linked issue).
Running "gnome-control-center" from the command line details the following error:
(gnome-control-center:4583): Gdk-WARNING **: The program 'gnome-control-center' received an X Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadContext'.
(Details: serial 158 error_code 171 request_code 154 minor_code 6)
(Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

Just completed setting up dual monitors on my computer, it's a dual boot Debian with Squeeze on disk one and Sid on disk two. My problem is that everything is working properly on Squeeze, but any changes I make to system settings in Sid setting up my second monitor are not being accepted. I'm at a point where I have redone everything twice and with no effect, can some one point me to some effective documentation or something I can use to correct this condition.

I have a working RHEL in /dev/sda1 and a newly constructed Ubuntu Lucid in /dev/sda2. I'm going to edit the grub config and reboot the server into the new Ubuntu. However, I'm not 100% sure that the new distro can boot. And since my only way to access the server is via SSH, I need the network to be up too.
How can I configure Grub and Ubuntu so that if the server fails to boot, it will automatically reboot into the old RHEL? Currently using GRUB 0.93, but I can upgrade it if needed.
Update: In the end, no boot failure occured. But without the insurance from this, I wouldn't have attempted [URL]..

I'm running Kubuntu natty on grub-efi-amd64. I've just received notification of a bunch of new packages to install, I believe part of it is a kernel update. When I click on "apply" a window comes up which says "Additional changes are required to complete the task". "2 packages to remove" lists "grub-efi" and "grub-efi-amd64". It lists 5 packages to install 3 of which are linux kernel and 2 of which are the bios version of grub.
How can I update my system without having efi-grub removed?

I am running Wheezy 7.9 and recently created a file, in xorg.conf.d, to set the monitor configuration because the EDID is not always read from the monitor. Everything works great but when the EDID is not read the monitor name, as shown in System Settings>Displays, shows as Unknown. I have the vendor info and modelname in the config file but they do not show in the Display GUI. Is there some variable that I can set in order to get a good monitor name displayed?
Probably should include some more information. I am using the Gnome Classic desktop and gdm manager. Here is the monitor conf file that I put in /etc/X11/xorg,conf.d
Code: Select allSection "Monitor"
Identifier "Monitor0"
VendorName "VSC"
ModelName "VA912b"
DisplaySize 376 301
HorizSync 30.0 - 82.0
VertRefresh 50.0 - 85.0

I am not sure where to post that so I'll just try here.My main question is: How can I prevent the system from changing my cpufreq settings? I'd like to keep the CPU load as low as possible so these settings are probably the best.However when I run some applications that require a higher CPU load the system changes the governor to performance and the rang to 0.8 - 2.4 GHz.And that's my problem. I neither know what application exactly is responsible for changing my cpufreq settings nor do I know how to turn that off.Or is it supposed to be that way?

I am running Ubuntu 10.10 and I have been keeping it updated via update manager.Last night the update manager popped up and I selected to update all required updates without checking what the updates were.While shutting down I noticed that I needed to reboot to complete the update, so I rebooted.After reboot the wireless network card disappeared. So I moved the PC and plugged in the ethernet cable. Oddly sometimes it shows disconnected for no reason and I have to reboot.What's even worst is that Ubuntu now locks up completely within 15 minutes of a reboot.None of the alt+sysrq commands do anything!How do I find out what the updates were and is there any way to I revert my system back to pre updates without having to reinstall?

Is there a way I can save system settings and have yast revert to a config file in case I ever need to reinstall the system again? I hate having to configure the firewall, runlevels, samba shares, samba workgroup, apparmor, and all the other junk after every install. It's not like I install often, but should suse 11.5 or 12 roll out, I'd like it to be a snappy upgrade.

I have two partitions with Debian on them. One is straight Debian and I installed Grub to the MBR. Another is Linux Mint LMDE and I installed (or so I think) grub to the root partition. Mint is not listed when Debian boots up and there's no entry for it. What did I do wrong? I'm not familiar with Grub 2. Is there some 'update grub' command that I need to use? Why doesn't this get configured when the other OS is installed? Or is this just how it works? I suppose grub will work for the other OS. If I 'update' Grub with my Debian system, it will "detect" the new OS, maybe? I wanted the current Grub in my Debian install to handle everything since the Mint install isn't my main system and just experimental for me.

yesterday I updated my squeeze amd64 on my Phenom X4 and now it is not booting anymore. Have you experienced the same problem?
After that I noticed the shutdown was not working anymore, it just restarted instead of powering down. This morning it wouldn't boot squeeze anymore, when grub starts and prints "Welcome to grub" (or something like that) the list of operating systems is not shown.
I noticed the updated also included grub and I saw it correctly detected my operating systems.
I am planning to boot knoppix soon and try to reinstall grub from chroot, but currently I am at work.

I added by error a fresh physical volume of a volume group to a logical volume:
lvextend /dev/lvm/logo /dev/md4
Is there a way to remove the physical volume /dev/md4 from /dev/lvm/logo again without harming the existing file system? I did not resize the file system yet.
I am looking for something like
lvreduce /dev/lvm/logo /dev/md4
but lvreduce only works with the -l or -L options as far I can see. So how can I ensure that only extends located on /dev/md4 are removed from /dev/lvm/logo?
This is the current situation:
Finding all volume groups
Finding volume group "lvm"
--- Volume group ---
VG Name lvm

i've been using ubuntu with wubi, and I'd like to install it on my new hard drive (so windows is on one hdd and ubuntu is on another). afaik, grub will be installed on the hdd w/ ubuntu, and i have to set it to recognize the other (windows) hdd. assuming that i want to get rid of ubuntu and just use windows, what steps do I have to take to do so? (if grub is only on the ubuntu hdd, then would I just have to format it?)

I cannot update my system either with Update Manager nor with Synaptic. The system tries to download the updates, and then generates an error message that I have broken packages. So, I click on Fix Broken Packages, etc., and when running get the following error message:
E: /var/cache/apt/archives/libavcodec52_5%3a0.6.3-0.0_i386.deb: short read on buffer copy for backend dpkg-deb during `./usr/lib/i686/cmov/libavcodec.so.52.72.2'
This appears to me to be a system bug. I'm running the 32-bit version of Squeeze. Re-install, or ?
