I have an old laptop that I installed EasyPeasy Lucid on. I have never used Grub2 as my other Ubuntu installs still use Grub Legacy. I have studied all the tutorials which instruct that the grub.cfg file should not be edited directly.This old laptop has one of the dreaded Intel graphics chips for which the kernel automatically loads the i915 module. Of course (like a multitude of others with Intel graphics and Lucid) I booted into a black screen but knew the workaround was to enable mode setting through grubI used the
Code:
i915.modeset=1
and added it to /etc/default/grub line GRUB_CMDLINE_LINUX, just after "quite splash", just

I have installed Sabayon 5.4 on my laptop besides Ubuntu 10.10. During installation of Sabayon I did not opt for a bootloader as I did not want to disturb the already existing Grub2 on MBR from my Ubuntu installation.After successful installation of Sabayon, I booted into Ubuntu and updated the Grub which detected Sabayon correctly. Then I rebooted and tried to boot into Sabayon but I could not do so. The booting process stopped with the following error -
Code:
Activating mdev
Detected real-root as md device. Setting up device node
Scanning for Volume Groups
[code]....
So evidently, Grub has wrongly taken the values of root as /dev/md0 and swap as /dev/sda2.I again went back to Grub2 screen edited the Sabayon entry by replacing /dev/md0- with /dev/sda4 and swap:/dev/sda2 with swap:/dev/sda8 and pressed Ctrl+x. Now I was able to boot into Sabayon. how do I make these changes permanent. Which files should I edit so that Grub correctly read root as /dev/sda4 and swap as /dev/sda8?
9.10 uses GRUB2, so the instructions below are obsolete. Is there anyone here who could provide instructions for adding Geexbox into the GRUB2 menu? If you already have a Linux OS installed on your system, you might just want to add a GeeXboX entry to your existing bootloader. This allow you to install GeeXboX very easily. From GeeXboX CD, simply copy the GEEXBOX folder into your Linux / partition (we suppose it to be /dev/sda1 here).
Modify the /boot/grub/menu.lst file to add:
title GeeXboX
root (hd0,1)
kernel /GEEXBOX/boot/vmlinuz root=/dev/ram0 rw rdinit=linuxrc boot=UUID=$my_uuid lang=en keymap=qwerty splash ...
initrd /GEEXBOX/boot/initrd.gz
quiet
Just take are about two things:
- the field root (hd0,1) is to be adapted according to the rest of your GRUB's configuration.
- the $my_uuid value is the unique ID of your partition. Check within your GRUB config file, which value is set for other OS on the same partition or use ls -l /dev/disk/by-uuid/ to see which uuid matches your partition.
I've reduced my Grub2 menu(using Ubuntu 10.04) list to only 1 item.I want to automatically boot into the one item without providing a password (it does this now). I also want to disable someone from being able to bring up the Grub2 menu and hit 'e' to edit the menu item. Any ideas how to do that? I've been sifting through the forums, but I haven't had any luck finding a post about this

I am using wubi and the win 7 bootloader, I still have the splash screen of grub 2 after I select Ubuntu off the win7 boot loader. I really don't think I need this. Could I get rid of the grub 2 loader, it really doesn't serve any purpose except take up boot up time? go easy, it took me a while to figure out how to shorten the DEFAULT boot load time in grub 2

I have a Debian Lenny box with two hard drives in it (no dual boot; /home and /var are on the second drive). This machine was working fine until earlier this week when I ran an upgrade and restarted it. I think during this upgrade Grub got upgraded to Grub2, and now when I try to reboot I just get this:
Code:
GRUB Read Error
Hitting Enter yields Operating System Not found. This is it, I can't get into the grub screen to enter the boot command or anything. I booted the machine into the rescue environment on the Install CD, and was able to mount all the file systems and chroot in. I tried reinstalling grub2, but this did not help. I ran fsck on my /boot file system, but it appears fine. The boot partition is also marked with a bootable flag in fdisk. I did try to downgrade back to grub1.5 which, while it didn't given an error did hang shortly after it loaded.

I have Intel X25-V SSD connected to linux machine and its status is shown as "[sdb] Write cache: enabled, read cache: enabled" in dmesg. I knew we can disable write cache using hdparm. Is there any way to disable read cache and is this read cache present on SSD ?
View 1 Replies View RelatedI created a quicktime .mov movie file in iMovie on a Mac (that is not available anymore) and I want to 1) play & 2) edit the movie. I'd be happy to use a different format if I can figure out how to change it. Has anyone else done this?
Edit: If you skip down to post #16 you'll see I discovered it actually isn't a matter of editing a .mov file, but it turns out I don't have a properly exported quicktime .mov file. Instead I have (I'm not sure but I think its iMovie ver. 4.) 1) an .iMovieProj text file that lists the cuts by frame in and frame out, 2) an .mov file that isn't the complete file I thought it was and 3) a folder of all the clips that are in Apple's Quicktime DV format. In this thread people taught me about transcoding from the Apple's Quicktime DV format to liberated formats easier to work with. Given this knowledge and since I have a list of the cuts I'm asking if people could recommend a Linux video editor that would be easy to enter the tedious frame in, frame out info so I could reassemble the video.
This started a while back... but I'm not sure when. Whenever I'm editing one of my PHP files it takes 1+ seconds for it to write the letter I type. I tried it on HTML and it's perfectly fine. I tried going to .gconf/apps and deleting the gedit-2 file, but it didn't help. And I tried disabling the File Browser Pane plugin and it did nothing. And one more thing, it might just be some PHP files, because about half of mine are really slow like that, but the other half is perfectly fine.

I use Mac OS X, and I wonder it's common in UNIX. In this case, is there any way to keep B as a (soft link) to A? Or, make B as the hard link would be the only way to solve this issue? What's the advantage of using soft link than hard link? The editor that I use is 'TextMate' on Mac.

Im running debian lenny if it helps.
I decided to try Ubuntu 10.10 after I had enough audio driver errors on my Acer netbook ( it came with windows wtf why errors) to drive me crazy. Anyway since I installed Ubuntu its ran better then when it was new my question arises here tho. I need to do some basic video editing (combine a few avi files, add transitions, add effects, etc) I don't need some end all to do all editor. just something basic like the windows. Video editor thingy was. So far I've tried pitivi which crashes, open soft which also seems to dislike me, and kdenlive which shows some promise but seems to be slow and needs libmp3lame.
I tried to install it and while my software manager thing says its installed kden says its not. I wanted to try lives editor but my terminal abilities are almost non-existent. Is there an editor I haven't tried that could be what I'm looking for? Is there a way to fix kden? I just want to edit the video and put it on Facebook. I'm willing to learn and I'm not a computer idiot just a Linux one. I really don't want go back to windows cause ill have to reinstall it and even when I do that with the disc Acer sent me windows makes a screeching noise even when then sound is off and locks up.
what if the root user by mistakenly stops/starts any service and tried to remove those traces from the log files and save those log files. Then how can we ensure that our log file is trusted. Is there any way where even the root(superuser) also cant edit/modify the contents of the /var/log/* files.
