I used testdisk to undelete some files and in the process accidentally moved my partitions around (swap file was sda5 now it's sda3). Now I am getting the "no swap%" error from Conky. This is in Conky, I've already checked the UUID's with my partitions and fstab file.

View 4 Replies View RelatedI have recently installed Lucid Lynx and am enjoying it immensely.I was just wondering if anyone can help me with setting up Conky to work with the Compiz wallpaper plugin.I've disabled Nautilus from drawing my desktop to enable multiple wallpapers in Compiz, but now I can't get Conky to show up on the desktop. Can anyone who's done this in Lynx post their .conkyrc files please?I've tried googling around for a solution, but most of the threads I came across were from 2007-2009, and some of the configuration options for Compiz have been updated since then. It'd be cool if I can still use conky in my multi-paper environment.

I know I have to set up the rule under Widget Layer > Behaviour > Widget Windows but i have not been able to identify the correct rule.
I have conky running a simple script on my Ubuntu 11.04 install. Running conky from using ALT-F2 is fine, but I have have conky added to the startup list, and when it runs from this, the conky window is different (ie not integrated with desktop layer). It has some shadowing around the edge and it seems to be on a layer other than the desktop. In addition to this, it stops running after a short while. I then run conky from ALT-F2 again and it's appears as I want, and stays there all day. I have included what I think is the relevant code below from my conkyrc. Has anyone had similar issues with a suitable way to resolve the problem?
Code:
own_window yes
own_window_transparent yes
own_window_type override
#own_window_type desktop
#own_window_type normal
#
own_window_type conky
own_window_class Conky
I had a drive with a partition layout like so:
~50gig Windows 7 - NTFS
~100gig Ubuntu - EXT3
~100gig Snow Leopard - HFS+
~100gig Extended Partition
-- ~100gig Swap Disk - exFat
I wanted to delete the Snow Leopard partition and format the Swap Disk partition to something else. exFat was causing major file size bloat on small files. QT sdk bloated to like 11 gigs or something ridiculous like that. Anyways, I loaded up an Ubuntu 10.04 LTS live cd and gparted then deleted the Snow Leopard partition. Gparted said "Mission Accomplished" and tried to rescan the drive, but never found it. At this point I restarted the computer, a dell laptop, which didn't boot with an unable to find a bootable device error. The ubuntu live cd doesn't see the drive anymore. gparted scans for drives indefinitely and fdisk -l has no output.
i would like to set up a conky setting at my work so when employees call me for questions they can just give me the info that is visually on the screen from conky that i want instead of having them look for it, i have done some conky in ubuntu , it is very easy , just install it then enter codes in the text editor, and BAM done, now on opensuse looking at this thread Conky - Hardware Monitor it looks ALOT harder, is there a easier way around this big mess of codes and what not.
View 9 Replies View RelatedI was reading another thread about someone with a bad partition table and I decided to join this forum. I'm not going to take any drastic actions with the partition (/dev/sda3) in question. I am going to wait for instructions on what to do first. I am not very good with Linux and need some hand holding. System: DELL 4550 Dual-Booted with XP and Ubuntu. Works OK, just no swap. Well, here's what I did: I deleted a partition for Windows XP Pro because it was a trial, and it ran out. I then decided to slide the swap partition for the Ubuntu Linux that I dual-boot into over. (If this was successful, I was going to try expanding the root partition to take up the unused space.) I used Gparted on a CD to do this, as I figured it was safe to do.
I now cannot mount the swap space at bootup (and have to go into a backup version of the OS), although I can use Gparted in Linux to execute the "swapon" command, and it appears that it worked because I now see "swapoff" as an option on the context menu. (I actually don't even need a swap partition, except to hibernate.) If I highlight the swap partition and click on "Drive" on Gparted's menu bar and select "Create Partition Table", it will erase all data on /dev/sda, so how do I fix the bad partition table non-destructively?
I am having issues with Grub 2 after installing Debian 7.8.0.The computer is a HP Pavilion 500-307nb. I made the original harddrive /dev/sdb and inserted a Samsung Evo 840 as /dev/sda. From the original hard drive (/dev/sdb), I wiped the windows partition, but left all other partitions unchanged (in case I would ever want to recover the desktop to its original state). I replaced the wiped windows partition with a swap partition and an LVM partition.These are my hard drive partitions:
/dev/sda (Samsung Evo 840)
Number Start End Size File system Name Flags
1 1049kB 3146kB 2097kB primary bios_grub
2 3146kB 944MB 941MB ext4 boot
3 944MB 94.4GB 93.4GB host lvm
4 94.4GB 1000GB 906GB guests lvm
[code]....
The partition /dev/sda3 has 2 logical volumes with filesystem ext4 that I mount to / and /home.The partition /dev/sda2 is mounted to /boot..When I install like this, Debian installs fine, however Grub2 is not installed correctly.Debian installs grub-pc which seems not able to boot the gpt partition. So I boot the Debian CD in rescue mode and execute:
mount /dev/sda2 /boot
aptitude purge grub-pc
aptitude -y install grub-efi
After rebooting, I come in the grub rescue shell, which says: error: no such device: 986f2176--4a4b-4222-83b9-8636a034b3c7.
When I then enter in the grub rescue shell:
set boot=(hd0,gpt2)
set prefix=(hd0,gpt2)/grub
insmod normal
normal
Grub and Debian start up correctly.why can Grub not start up automatically correctly? Where does the UUID 986f2176--4a4b-4222-83b9-8636a034b3c7 come from? I have reinstalled Grub several times, I have reinstall Debian several times, I have even wiped all partitions from /dev/sda and recreated a new gpt table with parted and manually set the partitions in parted. Still on each reinstallation, Grub fails because it cannot find exactly the same UUID. Since this UUID is always the same, it must be stored somewhere, but it cannot be the partitions, I have wiped them and the partition table several times.
I did though a firmware update of the Samsung Evo 840 before reinstallation, could this be a cause?Also the problem is not in grub.cfg. Grub starts correctly if I enter the commands above in the grub rescue screen and the UUID value does not appear there.
I wonder whether to place swap partition on LVM or on standard fdisk partition which will not be in LVM.What is better and more often used on production ?
View 4 Replies View RelatedI've recently just installed ubuntu 11.04 but seem to have made a big mistake. During the install process I was asked to specify a location to be used for swap. Not really understanding what this meant I chose another partition on my drive with some free space but also a lot of my data. Needless to say I now cant see that partition. Is there anyway for me to access it? or to at least recover the information I need from there? its about a 200gig partition, and it used to be ntfs.
View 2 Replies View RelatedI'm in the process of setting up my very first ubuntu server.
Using 10.04 and has 2gb ram
I am using Ubuntu's software raid (mdadm)
It will be a file server, with 4 hard drives (3 in RAID5 and 1 as a spare)
All 4 drives have 2 partitions:
Partition 1 - 100mb
Partition 2 - The remaining drive space
I setup the first 3 drives' partition 1's to be RAID1 with the 4th drive's partition 1 as a spare. This is where I'm mounting "/boot" (it's my understanding that /boot cannot be on a RAID5). I setup the first 3 drives' partition 2's to be RAID5 with the 4th drive's partition 2 as a spare. This its where I'm mounting. I believe so far I'm setup correctly to be able to deal with a drive failure and the system should operate just fine. What I don't know what to do is with the /swap. I want to retain the ability to be able to operate with a drive going down. But I have also read warnings about putting /swap on a raid. How would you setup /swap?
How can I add more space to my drive since I only have 1gb of ram and plenty of hard drive space? Right now it does not seem to be utilizing the swap space very efficiently.

View 2 Replies View RelatedSetting up a randomly passworded swap partition in Debian installer with the default settings (aes-xts-plain64 w/ AES-256 key strength) gives the following line in /etc/crypttab:
Code: Select all####_crypt /dev/#### /dev/urandom cipher=aes-xts-plain64,size=256,swap
However according to cryptsetup manpage when using XTS mode the key size must be doubled so in effect the 'size=256' parameter above is actually resulting in AES-128 strength, no? To get 256 bit key length the size option should be set to 512. Quote from cryptsetup manpage:
For XTS mode (a possible future default), use "aes-xts-plain" or better "aes-xts-plain64" as cipher specification and optionally set a key size of 512 bits with the -s option. Key size for XTS mode is twice that for other modes for the same security level.
My motherboard supports up to 8GB DDR2. I currently have 4GB installed. If I maxed out my RAM, and installed 10.10 without a swap partition, I've heard this would increase speeds significantly. Would it? This particular rig runs multiple servers including an Asterisk PBX with FreePBX, XBMC, and Boxee. XBMC and Boxee do not run at the same time, only one at a time. Would it be safe to run with 8GB ram, and no swap partition? Running FreePBX/asterisk, XBMC, playing videos or ....., and every other background processes, free shows on average 50% free. Opinions?

It was working, but then I tried to swap caps lock and control.
I used:
System->Preferences->Keyboard
Layouts->USA->Options
Then, under Control Key Position, I selected swap caps lock and control.
Now, my keyboard won't work in the Keyboard Preferences test area or in any other window or when the screen-lock comes on.
I tried logging out. I tried rebooting. I tried deleting my .gnome2 directory. Nothing seems to work. I can use the keyboard on other accounts, so the keyboard is not the problem.

View 3 Replies View RelatedI recently installed Ubuntu Server, the 8.04LTS release, on my dad's computer which, for the time being, has to dual-act as both a server and a desktop. Will be running solely as a server pretty soon, though. Anyway - since I was down on the budget and the project I put up the server for is still in a development phase and not worth to invest serious money in (at this stage), it has to run on a computer with the following hardware configuration (I left out the non-important parts):
Code:
Intel Celeron 2.2 Ghz
~500 MB of DDR 333MHz RAM
It has 80 or so GBs of disk space, so I went for the low-mem, high-disk scenario and created a swap partition of 1,5 GB. However, I can notice that is rarely even used! I have set the vm.swappiness parameter to 95 but my swap partition is still not being used, even when the memory usage goes up to 90%. I saw it being used once, but only when the needed memory size exceeded 500.
Does anybody know how to force Ubuntu Server to use the swap partition?
I read an article earlier that suggested the swap partition is encrypted by default if you select an encrypted /home folder during installation, is that true (for Lucid)? I am suspecting it isn't because my hibernation works, which I believe shouldn't be the case?

View 9 Replies View RelatedI have a live/persistent installs of Lubuntu 10.04 on a USB-HDD. It's on a 320 GB portable drive. I've partitioned it so that 80 GB is for the Lubuntu live install and the remaining 240 GB is another partition dedicated to storing stuff. So this USB-HDD is doing double duty. The thing is, I was paying so much attention to making the persistent install work without making a mess of the boot loader (I did that in the past; twice!) that I had overlooked the fact my live install does not have a swap sartition on it. I just assumed (incorrectly) that the swap partition on would just be part and parcel of the installation. Can anyone tell me of a way to add a swap partition to each of my live installs? Without losing any data or anything like that. It's probably not doing any harm not having a swap partition, but I'm assuming that my live install would be that much more efficient with it.
View 7 Replies View RelatedAfter unsuccessfully trying to install Oracle Express I find that for some reason the swap partition on my server disk does not get used.
My setup: 10.10 server x64 on an intel server with two 500gb HDs in a mirror array
This is puzzling, because I definitely created a swap partition for this system and indeed if I look at /etc/fstab I actually have two swap partitions, one on /dev/mapper/[some long raid name]_ar05 and one on /dev/mapper/cryptswap1, but AFAIK this is normal with 10.10.
"swapon -a" fails with this message:
Code:
swapon: /dev/mapper/[raid name]_ar05: read swap header failed: Invalid argument
swapon: /dev/mapper/cryptswap1: stat failed: No such file or directory
there's always the option of using a file on the server's filesystem, but I want to see if this can be fixed. I only have remote access to server via SSH, which makes startup troubleshooting pretty impossible.
I have a local server at home also using 10.10 server 64-bit with an encrypted swap file running on a RAID array, but it does not have this problem.
I didn't like the fact that Ubuntu allocated like 5gigs of swap with its automatic partitioning / install. So I decided to shrink it with gparted now it doesn't show up when I boot I have to select swap on in gparted to use it.
