Ubuntu Installation :: Refresh - Restore Current Installation Without FULL Reinstallation
Apr 7, 2011
I installed Ubuntu Lucid Lynx a while ago. but then upgraded it to 10.10
I don't have the CD with me right now and i need to fix some mistakes of mine (being a n00b to ubuntu) urgently i.e. i can't wait for morning. Is there anyway i can rollback to the time when my ubuntu installation was in mint condition?
One more thing. Let me tell you my mistake. Almost a month ago i installed Apache2 on my Laptop (for LAMP). and now i have to install Apache Tomcat for JSP development. but the problem is that the files made by Apache2 and the PHP5 installation i made are not removed with
Code:
Code:
So now the apache2 files are superseding the Apache Tomcat. hence i cannot distuinguish between apache2 or apache tomcat when i goto:
Code:
So if anyone has a way of ridding my laptop of this disease without complete overhaul, please post your replies here.
Until then, I will have to defect back to Windows.

Regarding dual boot and GRUB. Here is my situation: Year ago I bought computer i7-920 6G one HDD, I installed windows 7 on it. than I bought second HDD, placed it into master 2 position and installed ubuntu on it. after installation of ubuntu I got GRUB loader as first thing when I start computer (I don't remember the particular settings during installation) So far so good now is the question - is GRUB on the first or on the second HDD? can I swap both harddrives so the ubuntu one will be in master 1 position? I'm asking because my windows 7 is now wrecked (can't even get it to safe mode) and I need to clean the first HDD and reinstall windows.

I'm using ubuntu 10.04 and it seems that I forgot to set up a swap partition when I installed my system. So, I can't install hibernate, and I don't think I have any virtual memory any more.
I know that I can always set up a swap file to play the same role, but since swap file is not contiguously stored on hard disk, the performance is expected to be worse than a swap partition.
So, how can I add a swap partition and make my system boot with it every time from now on? I have unused space on my hard disk, and re-installation is NOT an option.

I "USED" to have a dual booting pc...with Windows 7 & ubuntu 10.04.(NOT Wubi) 2 Days back my windows 7 crashed...so i had to reinstall windows 7. But after reinstallation there was no option to boot into ubuntu 10.04. My system automatically boots into windows 7. I need to fix my ubuntu installation so that i get an option to select which OS to boot...at the startup.

I can not boot into F9 after the reinstallation of Window XP. So I booted from the F9 live cd and tried to repair the grub. Here is what I did in the terminal:
Code:
[fedora@localhost ~]$ grub
bash: grub: command not found
[fedora@localhost ~]$ whereis grub
grub: /sbin/grub /usr/share/grub /usr/share/man/man8/grub.8.gz
[fedora@localhost ~]$ su
[root@localhost fedora]# /sbin/grub
[Code]...

I updated my laptop to Ubuntu 10.04 and among the many problems I've had is this strange one with Thunderbird 3. It will not refresh it's window. That is, it loads, and some of the panes (such as the one on the bottom right that shows the selected message) remain blank.
The work around I found is to grab the title bar and move the window. That will force a refresh, but it is terribly annoying to write a message and not see the words until I stop and move the window a hair.
This behavior happens when the Appearance settings (System > Preferences > Appearance > Visual effect) are set to "Normal" or "Extra". Under "none" Thunderbird behaves normally, but everything else looks terrible!
I'm guessing this is a Compiz problem; has anyone else seen this happen? more importantly, how do I fix it? and all other programs work fine under all appearance settings.

I disconnect my internal Windows hard drive first. Then run the installer from the Desktop CD. Everything works great.This is approximately the steps I take: I reboot, everything is good. I reconnect my internal hard drive, boot to Windows, reboot back to Kubuntu, everything is still good. I run updates and follow the instructions of the Comprehensive Multimedia & Video Howto. I reboot again, still no problems. At this point, I figure everything is OK and I have no worries. I boot to Windows and do some work in that environment. The next time I boot to the external Kubuntu hard drive, I get the following errors:
Begin: Starting AppArmor profiles ...
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /dev on /root/dev failed: No such file or directory

have tried to replace WindowsXP with ubuntu netbook 10.10 on my Acer Aspire one (model ZG5), I opted for erasing the disk completely to just have ubuntu on the machineit runs perfectly from the USB drive, but will not boot up after a full installation, I just get a black screen with flashing underscore cursorthere are several threads about this problem but I cannot glean a solution, I have used 2 downloads as I thought the first iso might be corrupted, but still cannot get the system to start upwhat is the next step, is it worth persevering or trying an alternative distro?

I want to install Ubuntu 10.04 to another machine alongside that other machine's XP. I know I could just run the install disc; but I'd like to take what changes I've made to Ubuntu along with it - for instance, TrueCrypt, Simple Backup, AdobeReader 3 (I think that's an addition), K3b, MuseScore, and some other applications I've added along the way. Also, I went thru some Terminal commands to get Brasero to copy CD's recently and would like to avoid doing that again.

I just got Ubuntu 9.10 CD from the Canonical Ltd. I started to Install Ubuntu 9.10.
It asked me to Select a language then it started loading
After a minute or two the screen showed some errors and my monitor showed an error non-supported refresh rates 35.xx KHz / 75.x Hz
I dont remember the exact numbers but this is the error. This error is generated by monitor's hardware not ubuntu.

I just upgraded to 10.04 and I've noticed some flickering on my monitor... if I'm correct, the problem is the refresh rate. It is set to 60 Hz and it doesn't give me any options to change it. I would guess that the display drivers are installed correctly because I'm running a lot of CompizConfig effects without a problem Is there anything else that could be causing this problem?

I just installed 10.04, it boots fine and gets to the desktop. I can navigate with my keyboard fine. but when i move the mouse around. after a few minutes the screen goes black leaving just the cursor. I can move the cursor around the black screen. then the screen resets like i did an auto adjust on the monitor and the black screen with the cursor comes back up. once again I can move the mouse. Then It "refreshes" again. Stays in this loop until I restart it. But nothing changes. I have re-installed twice.

Just installed Ubuntu 10.10 "Maverick Meerkat".
Install went through smoothly in both my laptop and an old Dell Optiplex GX 270.
Screen looks fine on laptop but terrible on the Dell. It's stuck on Refresh rate of 60Hz and flickers pretty bad. 60Hz is the only rate offered! How can I change the refresh rate to ~65-72Hz like is possible on earlier Ubuntu versions to ease eye strain?

I just installed Win7 (I need it for work -.-") and, of couse, it installed its boot loader and I can't boot F13 any longer. The question is, how do I restore GRUB from a F13 live installation media without destroying Win7?
I remeber trying something like that a couple of years before when I had the same issue:
Unfortunatelly, that doesn't work and at the next boot I am stuck with Windows again how to restore grub from a F13 live CD?

I have started once month ago using git locally in my computer to keep different version of my files.
For that I am using
Code:
git add file to add a new file to my git system
and
Code:
git commint
to commit changes.
Let's say that I am implementing a file called git.R and I have commited so far 4 times.
understand what is the best way
a) To check the differences between the changes I did to the file git.R
b) Restore as current git.R the third commit out of four I did
c) Restore the second commited git.R as git2.R

I try to stay max 3 releases behind with Fedora, and now it is time to upgrade from a well behaving Fedora 8 to Fedora 11, not to slip too far behind. I have an Intel motherboard with a 82865G video chip. My display is a BenQ FP731. Fedora 8 the display works nicely giving 1280x1024 resolution at 72 Hz. On Fedora 11 the 865G chip ensists on setting the refresh rate to 75 Hz. I have copied the xorg.conf I use in Fedora 8 to /etc/x11/xorg.conf in the Fedora 11 installation. The chip sets itself to 60 Hz or 75 Hz, but not the desired 72 Hz which would give clear picture. What am I missing here?
Below a copy of my xorg.conf that gives the crystal clear and desired 1280x1024 @ 72Hz in Fedora 8 but gives a shivering and unusable 1280 x 1024 @ 75 Hz in Fedora 11:
---- clip clip ----
# Xorg configuration created by system-config-display
#Section "Module"
#Load "glx"
#Load "dri"
#EndSection
#Section "Serverflags"

how the current full desktop stack looks like for Ubuntu Natty? I assume it should roughly look like this:
Unity
Compiz
Gnome
X
Is this correct? Any other levels that I missed? Where would Wayland stand (in the future) here? I assume it will just replace X?

Upon booting, the existing grub menu shows the Debian OS, but I also have Ubuntu installed on the same hard disk. It does not show in the menu. Previously I had Debian, Ubuntu, and Mint. In Ubuntu config file (menu.lst) I wanted to delete Mint and an old Ubuntu. I did so. In doing this I must have removed the 'full' menu.lst,leaving only Debian. So now I cannot boot into the new Ubuntu. I presently have only two OS on the hard disk: Debian and Ubuntu. I cant see Ubuntu, How do I correct this problem?

I would like to try the rawhide updates. If messed up my PC's couple of times so now before I do anything I would like to roll back changes and resort to last working kernel ( and related s/w) in case that fails . HOW do I do it? ( c.f Windows Last good session ) ALTERNATIVELY folks - is there a way you can backup and restore to full accuracy all your previous kernels .- I mean just inset the CD .It will identify the partitions , then it will ask you "where you want to restore them" and then it just restores the prev. image.

Even if you select all the packages when installing, it is not a full version. Many
packages are unavailable.
I remember that Red Hat Linux 9 has two options: Minimize and Everything.
The everything option will install a full version, which is
much larger and more abundant.
How can we do this for Fedora 9/10?

I bought a 30 GB SSD and I need to install Ubuntu on it. I currently have a 1500 GB harddrive, on it my current 60gb ubuntu partition and the rest is Windows 7.Out of the 60 GB for ubuntu I have used 9 GB, so I want to transfer that 9GB to the SSD to preserve all my settings. Then I want to format the original 60GB to something else, probably NTFS since both linux and windows can read it.I tried sbackup but that creates a back up on my current drive, not what I intended. If there is a gui program that will work that would be great, if not I'll still give whatever suggested a shot.

I had recently upgraded my 9.0.4 ubuntu to the latest version, but something must have gone horribly wrong during the upgrade. On boot, it says it has problems and errors loading stuff and when it gets to the desktop, it gets no input from the keyboard or the mouse. Same goes for recovery mode. When trying to run from a live CD the keyboard and mouse work just fine. I have the CD and I wanted to simply reinstall but problem is I don't know how to reinstall over the current installation.

I am going to dist-upgrade my 10.10 installation to 11.04, but as precaution, I would like to replicate my existing installation onto another hard disk and perform the dist-upgrade there. When I am in booted into my current 10.10 installation, the hard disk (MBR, 4GB) is partitioned as such:
/dev/sda1 - /boot
/dev/sda2 - swap
/dev/sda3 - /I have an empty hard disk (MBR, 10GB) connected to the PC, and I partitioned to have a similar layout.
/dev/sdb1 - /boot
/dev/sdb2 - swap
/dev/sdb3 - /Since the 2 HDDs are of different sizes, I made /dev/sdb3 larger.
My question is: what is the easiest way to create a backup of my current working Ubuntu onto my secondary hard disk? I hope to perform the backup while booted into my existing 10.10 system; or I have no other choices but to boot from a LiveCD (e.g. Clonezilla) for backup?
