This will show the number of open files per process ID: cd /proc for processid in [0-9]* do echo "Process ID = $processid: $(ls /proc/$processid/fd/ | wc -l) file descriptors" done (save and execute with sudo). Then you can track down what that process ID belongs to.

I have a laptop with 4GB of RAM and Ubuntu 16.04. After boot it consumes around 1GB of RAM and even then Inkscape (for example) won't run (System monitor shows more than 50% of free RAM). Inkscape freezes After I apply a swap file it runs as expected, even with no one single byte of swap being used). So I recommend a swap partition (or swap file). About the ...

My system claimed to have 8 GB (gigabyte) of RAM. Ubuntu says it has 7.7 GiB (gibibyte). 7.7 GiB (gibibyte) = 8.26781 GB (gigabyte) 8 Gb (gigabit) = 1 GB (gigabyte)

You have only 500 MB of RAM installed. I would not be surprised that most of it is in use, given those little resources. On the other hand, htop sums up both the really used memory (allocated by applications) and the cache (used by the system to cache disk access, but immediately available to applications if needed). Therefore the "non-free" memory amount ...

Tell Ubuntu to use more RAM to speed up the process Ubuntu does not control what the applications you're using do with available memory, the applications themselves do. So you'd need to find some way to tell the application you're using that it shold use more memory. However, most applications only use as much memory as they actually need - using more isn'...

Actually, there is nothing to choose here. There's just one option: Lubuntu. No other Ubuntu flavor would even get to the desktop! Mainly because video hardware limitations. If that is not fast enough for you, first install Lubuntu, then install another ultra-lite desktop environment in Lubuntu. Ultra-lite meaning Enlightenment, OpenBox, Icewm, Moksha, ...

LXDE LXDE is supposed to be lightweight and therefor a good choice for such small hardware setups. LXDE is what Lubuntu is using. From the project page LXDE is a GPL licensed open source desktop environment for Unix and other POSIX compliant platforms, such as Linux. The name LXDE stands for "Lightweight X11 Desktop Environment". LXDE is an ...

Your script is using a lot of CPU resources because it runs continuously, which is inefficient. To avoid this, add a call to sleep, which means that it will only do it's work once every 5 seconds, which is a lot more efficient. You can probably extend this to even more, like 60 seconds, depending on how frequent / accurate it needs to be. Here's what it ...

Alright I found the answer, it turns out that most of my RAM was full of cached memory. If you set up a cronjob to clear cached memory every hour or so kswapd0 never appears again.

Official Mozilla Support Answer Mozilla has a support document for this particular question. The document offers additional information - so it is worth a look. It also says that clicking the Clear Now button could take an unknown amount of time to clear all the caches (and it does clear all of them including the memory cache you want to clear) because ...

Try sudo top in a terminal. Then hit > or < until the Mem column is highlighted. The processes are then sorted by memory usage. Also, hit c to show the full command-line arguments of the processes. You won't see root's applications in gnome-system-monitor. Most-likely, the other 3Gigs are used by root either for lightdm or another process - background ...

I was just having the same problem and read in another post that Ubuntu somehow locks the SD once it's been improperly removed. Anyone who gets the "Destination is read-only" message check that the locking switch in the SD to MicroSD adapter is not in Lock mode, and if that's true, try again after logging out of Ubuntu and logging back in. Worked for me in ...

I realize this is an old post however, dmidecode doesn't report the actual RAM speed or its overclocked setting, it reports whatever is hardcoded in the ram chips themselves. If the ram is coded at 1600, dmidecode generally calls out 800mhz as others mentioned 800x2=1600. If you OC'd it to 2133 in your BIOS then you can rest assured it is OC'd to 2133 (your ...
