Ubuntu :: Get Rid Of GRUB Without Adversely Affecting Install?
Mar 6, 2010
Goal - have Ubuntu on one HDD and Win 7 on another. Sub-Goal - get rid of GRUB without adversely affecting Ubuntu install .I have three HDD's on my system; one contains Win 7 Pro (no complaints, love it), one is for storage (NTFS) and the third has Ubuntu on it (aside from the wireless issues and DVD playback issues, I love it as well).
All three drives are internal, but the Ubuntu drive is a special case. It's installed in a cradle that resides in an external bay. The Ubuntu drive can be turned on and off at will. I don't need GRUB (which will only confuse my fair lady).
So, if I run Win 7 recovery and "repair" the mbr, what will that do to the Ubuntu drive (which will be set as the first boot device in BIOS)? Will it boot per normal when the cradle is powered up, or will it be looking for GRUB?

Computer boots up fine, but drops to commandline as it tries to go to the desktop. Just logging in and issuing "startx" brings up the desktop and all is well.
The Xorg logfile gives no fatals or clues (at least to me), but the "warn" file in /var/log gives the following at the end:
Mar 13 13:25:43 xxxxxxxx kdm[2328]: X server startup timeout, terminating
Mar 13 13:25:43 xxxxxxxx kdm[2328]: X server for display :0 can't be started, session disabled
Yesterday was fine, and never had it before; no harware changes (still same ATI 4770 and ATI 11.2 driver), nor BIOS changes/updates, for ages. First boot today this started. Does it continuously.
how I might slightly increase X's timeout parameter a bit, if this is the problem?

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

I appear to be experiencing an annoying issue with my soundcard. As you can see from the images below, the soundcard is detected, but not when it comes to the "output". This is only affecting one user (my admin account is fine, as was a new user set up to test it).
I've looked at this page and have attempted reinstalling alsa, but to no success.
The results from aplay -l are:
Quote:
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
[Code]....
"stevek" being the user that I'm having difficulty with. I suspect that I might need to recreate part of my user profile, but I'm not sure where start.

I've got a weird wireless problem and I don't know why it is as it is... I've got 3 OSs installed: vista, Ubuntu 9.04 and 9.10 on an FS Amilo 2727 laptop, everything is fine in 9.04 but the wireless doesn't switch on in 9.10 until I do a "sudo modprobe acerhk" and then that runs, so things work with some fiddling and that's ok, what's weird is that if I don't activate the wireless in 9.10 and then reboot back into 9.04 the wireless in that then doesn't work and the "Enable Wireless" option is greyed out I have to go to vista and activate the wireless so I can get the wireless working in 9.04. you'd think each partition wouldn't affect the other ones but it obviously does.

I have a few partitions on my hard-drive, one for Ubuntu, one for Windows 7 and another for general data storage. When I installed Ubuntu, I was presented with a GUI which allowed me to easily reassign storage space from the latter two to create the former. Is there any way to get to something similar, from which I can adjust the proportions of the partition sizes, without affecting their content?

I was installing some packages using the generate download script in synaptic and 'sudo dpkg -i -R ...' because I don't have my own internet connection at home but somewhere else. I think I got carried away a little and installed some packages that have some dependency issues. Now I have three broken packages that need to be removed, but I don't want them to affect (remove) other packages which would be marked whenever I try to mark them for removal, for fear that their removal might affect other functions. I think my machine was just fine before I started to fumble with individual dependencies; that's why I don't what the other dependencies removed. My question is how do I remove those dependencies only using the terminal without removing the others?

I've been running 64-bit openSUSE 11.2 since shortly after it's release, on a quad core AMD Phenom based machine, using KDE as the Desktop. I have a USB-attached "multi-function" printer/scanner/etc., which worked fine with XSane under 11.1. On the same machine, with 11.2, I can still get a scan preview. But when I try a full scan, shortly after it starts, the progress bar stops, then XSane complains about an I/O error.
When I update openSUSE versions, if I can, I keep the old version completely intact, on the same machine. This includes the /home partition, I don't overwrite it. Sure it's a good deal more work to copy over the numerous files needed, but if there are any problems with the new software, it's extremely helpful to have a completely intact old environment for reference. I was able to do this, while updating 11.1 ==> 11.2. Booting the old 11.1 system on the same machine, I haven't encountered any scanning problems.
I haven't given a lot of details, because it's the same hardware, that should "in theory", mostly eliminate the hardware as a possible source of the problem. I'm hoping the problem can be resolved by focusing on any changes in SANE support, or XSANE itself, for USB attached scanners. It could be unrelated, but messages such as these are in /var/log/messages on the 11.2 sys:
Feb 3 17:45:03 toe-heaven kernel: [ 5881.313532] usb 3-1: usbfs: interface 0 claimed by usblp while 'xsane' sets config #1
Feb 3 17:45:03 toe-heaven kernel: [ 5881.313560] usb 3-1: usbfs: process 8214 (xsane) did not claim interface 1 before use
If XSane is doing things in the wrong order, I'm wondering if it would be a problem especially for a combined printer/scanner, or would the problem still occur if the printer and scanner were two physically separate devices? I checked and there are similar messages in /var/log/messages with 11.1. But if it is an error in the sequence in which XSane does things, could it somehow cause problems under 11.2, yet not 11.1? I tried to find anything which might be related to USB device handling, which perhaps could interact. I came across messages such as these in 11.2, but not 11.1:
Feb 4 15:15:10 toe-heaven udev-configure-printer: add /devices/pci0000:00/0000:00:02.0/usb3/3-1/3-1:1.0/usb/lp1
Feb 4 15:15:10 toe-heaven udev-configure-printer: parent devpath is /devices/pci0000:00/0000:00:02.0/usb3/3-1
Is USB printer handling somehow different under 11.2? With a combined printer/scanner, could there be an interaction? I did some experimenting. I kind'a thought a scan preview was just a scan at low res. So I tried to do full scans, starting with the lowest res., and increasing. I was able to do successful full scans at 100 or 150. But from 200 on up, the higher the res., the shorter the time to get an I/O error. I'd normally use 600 or above, to get what I feel is a good looking scan. At 600 the error report is practically immediate. It's almost as if the error only occurs above a certain threshold, of amount of data per unit time. I should mention, although it's a color scanner, I'm scanning a black and white doc., so using that mode of XSane.

I am having one problem though; In changing the Applications font in Appearance preferences, it changes the font used in Nautilus, which i do not want, as the font I am using does not have capitals. I only want the font on my panel Menus and/or Desktop, but not in Nautilus.
So what I want to know is this: can I set the font individually for Nautilus (or any app, for that matter)? If not, can I set the Applications font to the one I want for Nautilus, and then set an individual font for my panel Menu headings/Menus?

I have a user on my CentOS server who is not part of any group, just by themselves.
How can I give that user 777 permissions without affecting any other user on the server? I have chroot off, so I can see everything, but the user cannot write.
Do I use chown?

I have 3 c files(one of them forks out 5 instances) all writing to one log file. Now to avoid the confusion of opening and closing in each application or instance and running into a situation of not having closed a file I decided to open and close the log file inside the log function for each write.
So what I do currently is fopen, flock, fwrite, unlock, fclose for each write. All the log messages from all the files get written fine and there are no errors but I see a performance hit. The applications talk to each other using SHM(shared memory). So when I try to set a timer and check number of messages lets say I get X messages. Each time I remove or add a log call the number of messages changes. When it is a 1 sec or 5 sec timer it doesnt make a very big diff..few hundreds but when I check it over a longer period..every log call added decreases 1000 messages in count. So I want to know what is an efficient way of implementing the custom log across the application.

I am using pam module to set password policy in my SuSE linux machine. This is my /etc/pam.d/common-password file:
Now if root user tries to change the password of a normal user, giving the same password, it is throwing an error saying "Password has been already used. Choose another".
Example:
> passwd user1
> password1 (set successfully)
> passwd user1
> password1 (Password has been already used. Choose another)
This should not happen with the root user.

I have a new Dell Inspiron 1545 with a dual-boot setup: Kubuntu and Windows 7. A long, tedious story made short, I have Kubuntu working but cannot for the life of me get the wireless adapter to work in Windows 7. Since the Microsoft universal fix consists of reinstalling the OS, that's what I plan to do.
That said, I'm concerned that Windows will not just reinstall itself, but wipe out the boot record used by grub. I've invested enough time setting up Kubuntu that I really don't want to start from scratch (again) with both OSs.
How to reinstall Windows without wiping the boot record? If not (i.e. Windows will kill whatever grub has in place), is there a way to use the Kubuntu disc, or another linux disc, to reinstall grub afterward, thereby leaving the linux partitions intact?

Since last last week i've installed Windows 7 and OpenSuSe 11.2 linux several time in my laptop. Each time i do something and Linux boot menu disappears and i again install both operating system. I have installed linux for the first time 6 days before in my life.
I am trying to live without windows. I know i can't for more few months as there is problem in every step for me.
Now i have both os running perfectly and boot menu appearing perfectly.
There are 3 partitions in FAT32 created while installing linux for Windows files. Now i want to change it in to NTFS. All drive are empty.
##1 Is it ok if i reformat it in windows 7 and change to NTFS?
##2 Does it creates problem in GRUB boot menu?
##3 Is there any way to do this from Linux without any problem?
##4 Is there any way to change FAT32 into NTFS without affecting GRUB?
I'm tired by installing again and again. I don't want any more trouble for next 1 month.

I am building a minimal 6.2.2 linux kernel with slackware on an AMD athlon +1700 single core box.
In the lilo.conf file, there was originally only one entry, which was created by the slackware cd install.
Now, my questions are:
1.Does a person edit the lilo.conf files before or after they rerun lilo?
2. If that person edits the lilo.conf files before they rerun lilo, does the sequence of the entries in the lilo.conf files affect the manner in which lilo treats the new and old kernels? (e.g. If I put the new minimal kernel build as the first entry, will I get an error message saying that the kernel sizes do not match or that the iso image is too large, or some other strange error message?)
3. Are there any other lilo related problems, options, or tweaks that you think are pretty cool and that I might like to hear about?
4. Would I be better off using GRUB?(I don't like GRUB, but I'm throwing this one in here just for completeness.)

Recently I have noticed that at times my keyboard will act as though shift is pressed. That is, letters are capitalized and when i press a key, its shift equivalent is shown. I actually first noticed this behaviour on fedora 12 beta (i believe fedora has been using udev/DeviceKit since F11). At the time of F12 beta I was not aware of fedora using udev. Where can I find a comprehensive guide to setup udev? Or if it all fails, how to re-enable settings in xorg?
Here is what cat /var/log/Xorg.0.log | grep -A 5 -B 5 evdev shows

I need to strip the executable flag from all files within a certain directory and sub directories. Right now I'm doing it with a 2 step process
find /dir/ -type f -exec chmod ugo-x {} ;
find /dir/ -type d -exec chmod ugo+rx {} ;
Is it possible to modify the first line so that I can strip exec flag from all non-directory files? Since this needs to be done on a fairly regular basis across a lot of directories and files, I'd prefer not to use a bash script which would slow it down.
