I have my current computer set up with 2 HDDs in it. A 500GB with GRUB and Windows 7 on it and a 160GB HDD with Ubuntu on it.
I would like to someone replace Windows 7 with Ubuntu on the 500GB drive, but I'm not sure how I would be able to do this and still keep GRUB and such .
EDIT: I'd like to do this without re-installing anything.
I have the following HDDs in an LVM2 configuration on an F10 box running Mythtv :-
# pvscan
PV /dev/sda2 VG VolGroup00 lvm2 [297.88 GB / 0 free]
PV /dev/sdd1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
PV /dev/sdb1 VG VolGroup00 lvm2 [298.06 GB / 0 free]
PV /dev/sdc1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
Total: 4 [2.40 TB] / in use: 4 [2.40 TB] / in no VG: 0 [0 ]
The system never uses more than about 250GB of HDD at any one time, so I would like to remove /dev/sdd1 and /dev/sdc1 from the LV and then from the machine and leave /dev/sda and /dev/sdb alone.
Does anyone know that if I use the command "system-config-lvm" to reduce the total LVM size to say 580GB, whether all data is preserved (I don't have any way at this stage to backup up 250GB of data, unless I buy more HDDs and that is the whole point of this exercise anyway - remove the two terrabyte drives to be used as backup disks).
Once I am happy that the data is safe, I will use "pvmove" and "vgreduce" to remove both terrabyte drives.
i have fluxbox as my desktop manager but i want kde instead so i installed it and i don't know how to switch over to kde. will i have to remove fluxbox??

I am using Wine to play Sim City 2k, and the game doesn't show up in the taskbar. How can I use the Terminal to switch to it?

EDIT: Oh, great. I think a fire just broke out. I can hear the sirens, but I can't stop them! Crap!
EDIT2: You know, listening to these sirens really sucks. I had my city up to 130,000 people. I was just saving up enough money to buy an arcology when I tried to move SimCity to Desktop #2. Wine was not happy with this decision. My city is probably burned to the ground by now.
EDIT3: Ok, I just realised that I can stop the process from the System Monitor. Too little, too late I imagine. Oh well, I can probably rebuild it if I could just get to the window...
I installed Ubuntu 10.10 over Windows 7, getting rid of Win7. I have decided that I want to switch back to Windows 7, because of more compatibility. Windows 7 came pre-installed on my laptop. Is there any way I can recover it? I did a full install of Ubuntu 10.10.

i have Ubuntu 10.10 + Compiz, everything seems okay; but when i want to switch between open windows i have to click only on windows Caption Bar, Clicking on Form body dont bring that form to front
View 3 Replies View RelatedI somehow managed to screw up my 'switch between windows shortcut' when changing the settings for compiz. Now I cannot get it to work at all, despite trying to solutions on this and other forums. I removed compiz with the software center and my alt-tab shortcut still didn't work--although it IS enabled and set correctly in the System Settings > Keyboard Shortcuts menu. I reset the alt-tab combo so something else (alt-space, which works for its normal setting of bringing down the window's dropdown menu) but it still did not work to switch between windows.

I do have an old laptop optical drive I've been meaning to house in a USB enclosure. Is the cd/dvd route my only option?
View 2 Replies View RelatedI am switching to Ubuntu soon for security purposes. I have 3 hard drives, one with my OS, one with nothing, and one with all my junk. I was wondering if there is anyway that I can only reformat and install Ubuntu onto the drive with windows, reformat the empty drive, and then transfer files from my junk drive onto the empty drive, and then format the junk drive and move all of the files back onto the junk drive? Or is the junk drive accessible from Ubuntu and not worth trying to switch formats on?
View 6 Replies View RelatedI recently installed Ubuntu desktop, since I had been running my server as Ubuntu Server on a guest OS on Windows 7 and never really used the Windows part of the computer. Since then, I've been unable to use the mouse in a graphical environment for longer than a few minutes without it starting to act crazy. The mouse moves around normally, but won't respond to clicks (left, middle, or right) but the keyboard shortcuts still work. I'm not sure if things have changed since I last used Gnome though, but Alt+Tab is not working for me either when this happens. Sometimes, the active window is even behind another window, and isn't pulled to the foreground.
After a bit of frustrated clicking and jamming of buttons on the keyboard, sometimes the mouse kind of starts working because I'll notice a right click menu open. But, I am still unable to move windows or click on them to bring them to the foreground, and my mouse presses only work on the current window. And then, eventually, after about a minute or so, it'll stop respond again too.
I saw in one thread that someone had dead spaces where he couldn't click, so he installed and ran Gnome and that fixed it, but I tried using Ubuntu Classic and it is still giving me the same behavior. I'm actually posting this message now in links, because I can't use Firefox or Chrome well enough when it's hidden behind other windows.
I switched my htpc from windows xp to ubuntu 10.10 and since i switched my audio no longer works. these are my current stats. Please help im new to Linux so im not sure quite what to do. [URL]
View 5 Replies View RelatedWhen working in an XP VirtualBox I can't use Alt-Tab to switch to my Linux Apps as VirtualBox captures the keys for Windows. So I tended to make a lot of use on the Application list on the old System Tray/Taskbar. I could click on the application's entry in the taskbar and that application would come up. When I needed to return to the Windows App, I clicked again and the application would then minimise so I can see the Windows app. Also I have been using the SUPER button in conjunction with 'E' to raise the Home Directory (just to keep it consistent with Windows).

View 4 Replies View RelatedI have a very basic problem: My computer is attached to various light switches, central heating, powered windows etc. via RS232 and USB, using homemade custom logic boards. With this I can switch on and off lights, regulate room temperature, open windows etc. all by running some shell scripts on my system. I would now like to create a simple web frontend for this home automation.
What I want is a basic website with buttons, and when someone clicks a button on that website I want the webserver (apache ? ) to execute a script on the the server machine, triggering the rs232 hardware. The website is to be served by apache to make use of an existing structure. How (in what language) could I accomplish that? Javascript and Java are obviously out since they execute on the client, as far as I know PHP can't access the shell (which is probably a good thing), so what's left?
CGI? This will be deployed on an isolated private network secured the old-fashioned way (steel doors, guard dogs, landmines...), so I am not overly concerned about security, but of course it would be nice if the implementation offered at least some basic resistance to bored script kiddies...
change as I salvaged an old old computer and got it back into working order. Windows 7 kills the computer and the media being served is sluggish and slow.
The computer spec are as follows:

I have two HDs, one is a 80gb OS drive(Parallel ATA) and the other is a 1T storage drive (SATA). Well after each reboot they swap between /dev/sda and /dev/sdb, over and over again. One boot the OS is /dev/sda and the next its /dev/sdb, same goes for the second drive. This makes it difficult to setup fstab so it will mount the large storage drive on boot.

View 2 Replies View RelatedMy reality distortion field went through a polarity shift today, and nothing's been working like it should. After the 10,000th problem, I decided to just make room for a fresh lucid install and the accompanying stability. It worked well, then I had some sort of a boot error upon reboot. So then I just decided to reinstall. The problem is that neither of my 2 internal HDDs is registering. Currently sda is an 80GB drive with a slackware install, sdb is a 120GB with a 60GB mint partition and (upon previous install) 60GB lucid partition. I've got no important data on any of my partitions yet, but also no net connection. I have install dvds for lucid, mint kde 9, and slackware plus a gparted live. I'm seriously considering making this machine a slack standalone, but then I've got legacy nvidia drivers to deal with.

I'm new to the world of Ubuntu 10.10. My PC had windows Vista running on an 80GB HDD, and on Friday 03/12/10 I decided to install Ubuntu 10.10 on a second 160GB HDD. Wrongly I assumed I could simply have 2 HDD's in my PC and it would magically allow me to chose between Windows Vista and Ubuntu 10.10. Well that was 50 hours ago and I still can't get it to work. As you can see I have the results of my boot_info_script055.sh below.
PHP Code:
Boot Info Script 0.55 dated February 15th, 2010

Grub 2 isnstalled in the MBR of /dev/sda and looks on the same drive in partition # 1 for (,msdos1)/boot/grub.

i have a question regarding how data is placed on a media, for example the daily used hdd: when we talk about storage we often speak in heads sectors and cylinders. my question is if heads, sectors and cylinder is the true way data exists on a hdd platter?
lets take for example, disk_x
1000.2gb = 1000204886016 bytes
255 heads, 63 sectors/track 121601 cylinders.
fdisk -H 128 -S 32 /dev/disk_x each cylinder will be shrank to 2097152bytes, number of cylinders will grow to 476934. but everything will be much more aligned and readable or there is something i don't know and i will loose almost half of the total sector count on the hdd cause 63-32=31. i asked the partitioner just to use 32 sectors from each track and only 128 tracks of the cylinder.
or another example, if i have a cluster size of 4k. why not making each track use 56 sectors or 7 clusters. theoretically i have all files in my storage and each one of them occupies 14 clusters isn't it wiser to make it as described. what happens when i invoke fdisk -h -s params? what will be changed, the disc physically and the way it is accessed or only the partition table? you probably asking your self what the hell does this dude wants? i want to get maximum i/outputs and the widest bandwidth and the nicest readble partition tables and to understand better fdisk -H -S.
I whant to know,is HDD Regenerator for linux? I completely at linux and sometimes i need to create usb flash hdd regenerator for testing hdds.
