I installed grml-rescueboot
, placed Gparted iso file into /boot/grml
then ran grub-update
. Now there is a corresponding menu item in GRUB but choosing it does nothing i.e. the GRUB menu comes back instantly. What can be the problem?
Reza's questions
We have a computer whose CPU has 32 cores and it's going to be used for running programs by a few different users. Is there any way to restrict the number of cores each user can use at any time so that one user will not monopolize all the CPU power?
A laptop with broken screen that I access via SSH. The sudo apt-get autoremove
command gives me the following errors
cp: error writing ‘/tmp/mkinitramfs_zN6ZvT//lib/x86_64-linux-gnu/libpthread.so.0’: No space left on device
cp: failed to extend ‘/tmp/mkinitramfs_zN6ZvT//lib/x86_64-linux-gnu/libpthread.so.0’: No space left on device

I get similar errors from various other commands but gparted
tells me there is more than 20GB space left on the (single) partition on the laptop. Here is the output of df

I once ran thunderbird
with the sudo
command and now when I run it (with or without sudo
) it does not load my default profile. The files of my default profile are still in the .thunderbird
directory.
A process with name (command) "bash" is taking about 100% CPU power. When I use the kill
command to kill it I don't get any error messages but it nonetheless doesn't die. It doesn't belong to root. Here is the output of ps aux
for this process.

Here is the line for my root partition in fstab
:
UUID=ab358046-2feb-4837-8827-0a98cd22a899 / ext4 noatime,errors=remount-ro 0 1
and it's been like this for as far as I can remember. However when I click on files in Thunar and check their "last accessed" I see correct last access times. Why is this?
Xubuntu 14.04 on a Samsung laptop. Problem similar to the question posed here with the difference that I've not installed ubuntu-touch
. I had adb
installed which I then uninstalled and ran update-grub
but still not booting. Linux kernels up to 3.13.0.61 boot and work fine but newer versions give me this error OR just give me a blank screen.
initrd: Couldn't find data partition. Spawning adbd ...
So to summarize, I can't get any kernel newer than 3.13.0.61 to work.

When I open an application for which there is not enough memory, Ubuntu becomes unresponsive. The problem seems to arise from the way Ubuntu handles swap (as kswapd
hogs CPU usage in such a situation). Other operating systems I've used such as Windows or Mac OS warn you when there is not enough RAM available but in Ubuntu the system becomes unresponsive for quite a while. Sometimes I have to restart the computer.
I've had this problem with various versions of Ubuntu from Hardy Heron and with several different computers with different RAM sizes.
Folder B is obtained from (a copy of) folder A by an undelete application such as extundelete and therefore its structure is messed up. How can I determine if every file in B and its subfolders exists somewhere in A as well?
Here I'm assuming files have preserved names but the same question can be asked for when file comparison is done using file contents only.
I get this error after installing new updates. This is the output of VLC:

I get similar errors from Gmusicbrowser as well. I tried the solution suggested here without avail. Reinstalled VLC, Alsa and Pulse Audio but again no help.
An image viewer that
Can display (the embedded JPG inside) RAW files.
Supports rating images and can write the ratings into the files.
Does not need to "import" the images.
I don't know any. Shotwell requires images to be imported and Geeqie cannot write the ratings into the file (as far as I can tell). Gthumb cannot display the preview JPG in a RAW file.
I have a directory whose files have extension either .JPG or .NEF and I want to delete the files of the form X.NEF for which X.JPG does not exist in the directory. (X here can be any string.) I don't know how to do this other than by hand.
A more general situation is when you want to find all the files in a directory A which exist in directory B as well. (The first problem can be turned into the second one using mmv
.)

I swear it used to work in Saucy. Can it be a problem with the driver?
I need a way of assigning tags and numbers (like rating, importance, etc) to my files and also be able do queries and file operations based on these metadata. Just like a photo management software (e.g. F-spot) but for documents (PDF, DJVU, EPUB, etc).
This can be a file manager with extra abilities or a file indexing system. The only thing I've found so far is recoll however it doesn't allow me to assign tags to files.
By the way, I've been using XFCE for quite a while so if Gnome has such a software built-in, I may not know about it.
Xubuntu Saucy with 4GB RAM. When the computer is restarted and immediately after login, about 500 MB of RAM is taken according to free -m
. Then I run some programs and memory usage goes above 3 GM.
Now here is the problem: If I close all the open applications, still about 2.5 GB of memory is used but no thread accounts for all this memory. Here is the result of ps aux

and here the output of free -m
total used free shared buffers cached

As you can see (even though not all threads are shown in the picture) the memory taken by the threads won't add up to anything close to 2512/3949=64%.
So, what is taking up all this memory? Can it be the kernel treads (whose amount of memory is not displayed) or a leak in Ubuntu itself?
Something which may be relevant is that the ammount of used memory shown by XFCE task manager is significantly lower than what free -m
shows.
Is it possible to persuade Xubuntu to store file thumbnails for an external hard drive into the drive itself instead of the home folder?
Benefits include avoiding the ~/.thumbnails folder to get too large and avoiding too much writing on an SSD internal drive.
The external hdd in question is where I store several years worth of photography. I think even if I disable thumbnails in Thunar, applications like gthumb still cause them to be generated.
There are similar questions on this site but none of them answers mine. I have Xubuntu 13.10 with Shotwell installed from Ubuntu repository. I also installed "gnome online accounts" and "signon" but still can't publish to any website from shotwell.
When I click on the "publish" icon, a dialog appears with a few choices like Piwigo, Tumblr, etc but none of them works. Is there anything else I have to install? Thanks.
Update: I tried to install shotwell from PPA but I got this error:
dpkg: error processing /var/cache/apt/archives/shotwell_0.15.1-1~saucy1_amd64.deb (--unpack):
trying to overwrite '/usr/share/shotwell/ui/collection.ui', which is also in package shotwell-common 0.15.0-0ubuntu1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

OK, I have a laptop with an HDD drive and I also have a SSD drive. I would like to replace the former with the latter without having to reinstall everything. What I found after a bit of research was to use a live disk + an external hard drive + gparted to copy the whole Linux partition (in two steps) and then edit fstab.
Now I guess when Linux is installed, it assesses computer's hardware and therefore adjusts some software parameters. So I'm afraid doing the above may 'fool' the OS and result in sub-optimal performance w.r.t. the SSD. I don't know if this is right.
