At least everyday my Ubuntu 14.10 jams and I have to turn off the computer. It sometimes makes another problems.
Gedit can't stay longer than 5 minutes. After 5 minutes it closes itself. I heard that there aren't problems with Linux and it is Windows that is famous for its bluescreen.I don't think I installed unwanted softwares because I've got only the basic ones and problems didn't start the other day but in the day of installation. Can you help me? : )

Lots of Information is always helpful when trying to detect irregular freezes / crashes etc ... so any system Information  could be helpful

 

I dont know Ubuntu  so I hope if i am posting things that aren't Ubuntu relevent someone will correct it ....but I am sure you have the System information somewhere  which will show Hardware Specs, CPU, GPU, RAM ..... are you using Gnome ,Unity, Cinnamon  or what ever Desktop

 

Did Problems start recently after updates, or Theme changes ,  does anything else crash frequently like  browsers, libre office etc..

 

Try opening the Terminal and  Running Gedit from there....if and when it crashes it should  give you an error type message in the terminal .....copy and Post the result here

 

Thiis can give a lot of information as to why its crashing....

 

For the System freeze  there are system logs which could be interesting......again may be slightly different in Ubuntu

 

in the terminal  try

/var/log/syslog*

or


journalctl --since=today

you can change the last word to "yesterday" or whenever your last Freeze / crash was  and maybe post that....

 

If it was just Gedit crashing you could completely uninstall / re install  that may solve it...but as you have system freezes it may be a different issue  example :- some themes dont work well with some desktops....or a Kernel update can sometimes upset things..

 

The more Info you can post the quicker and easier it  will be for anyone to help

 

 

 

..

I don't know if Ubuntu has this  but I can give all system info from the terminal  with

inxi -F

But it may not be installed in Ubuntu..

I'm not sure that any of these commands will work in Ubuntu. I just tried them in LXLE which is based on Lubuntu 12.04 and none of them worked.

Cybbermouse, in addition to posting as much information as possible, and particularly any error messages when gedit crashes after opening it from the terminal, it would be helpful if you could copy and paste the outputs of the following commands into a post here:

free -m
ls /var/crash
grep -i 'gedit' /var/log/syslog
(There may or may not be any output for the last two commands)

You are right Al, Only inxi -F works.

 I know mine changed from the var/log/ syslog   to the Journal  one I wasn't sure if others still used it....  

journalctl --since=today

came in sometime around the Systemd  inclusion

What OS are you using? I just tried running this command on Kubuntu 14.04 and am still getting "journalctl: command not found"

Hi Cybbermouse

 

Can you please tell us about your PC?

How much ram

Processor type

Type of Video card if any.

How is Ubuntu installed.

 

 

Be Verbose
When you ask for support you should also include as much information about the problem as possible. Including all of the important details in your first post will greatly speed up the entire support process and allow our volunteers to better assist you. While you may think a particular error message isn't very helpful, it may be the key to resolving your issue. Some details we are looking for would include, but not be limited to:

  •     Your distribution's name (Mint, Ubuntu, Debian, etc), version (17, 14.04, 7, etc), and architecture (32-bit, 64-bit).
  •     Provide relevant information about your physical hardware or installed software.
  •     Share relevant log files, screenshots, detailed error messages, or anything else that could be used to troubleshoot your issue.

Some problems are more complicated than others and require additional work to isolate the issue. So, try not to overwhelm the user with possible conflicting information during the troubleshooting process.

About my PC:

Asus

Ubuntu 14.10  64 bit

Procesor : Inter Core i5-4200U CPU 1.60GHz x 4

731,1GB Disc

Memory : 3,7 GiB

Graphics : Intel Haswell Mobile

Drivers : NVIDIA Geforce

Firwall : Gufw

Ubuntu was installed using CD.

I installed Ubuntu (as my first Linux by the way) two weeks ago. I have problems with it every day. What problems?  For example :

• my OS often jams, crashes

• Gedit works only for few minutes

• I often lose my cursor. Exactly I can see the cursor on my screen but I can't click anything (even terminal)

• my cursor sometimes works very slowly

No, I don't have problems with mouse. I use a new-bought laptop and its built-in mouse

Commands :

Shadow warrior : Gedit run by Terminal seems not to make problems but I'm not sure. Your commands don't work with my OS, except journalctl, but 'no files found'.

It looks like the problem could be lack of memory, as your system was using over three quarters of the available memory when you ran free -m, and either you don't have a swap partition or it isn't being mounted at start-up. Also, the log files in /var/crash are memory intensive applications.

(swap is the equivalent of Windows paging file/virtual memory)

If you could now please post the outputs of the following commands, we should be able to tell whether your swap partition isn't being mounted, or if there isn't one.

sudo blkid
cat /etc/fstab
EDIT: It's been brought to my attention that your system seems to be using a lot of RAM, although as I use 32-bit Linux I'm not sure how much RAM 64-bit would typically use. However if you could also please post the output of the following command, we will be able to see what processes are using most RAM.

ps aux --sort -rss | head

My PC uses about 600MiB, That's without anything open.

Thanks for the info. I wonder what processes are using such an inordinate amount of RAM on Cybbermouse's computer.

@Al1000

     Sorry for late reply ....I was using My Manjaro box  (Arch Based)..which is the main laptop at the moment... and at Home I run a Gentoo machine.  A lot of things are very different it seems to Ubuntu based distros.. though I thought "journalctl --since=today" worked.... Though as Debian is only now adopting Systemd maybe Ubuntu hasn't..

 

Re- The High Ram  ...Is it possible to post a screenshot of "HTop" if you have that on your system.  try typing htop  in the terminal that would show whats using what..

 

.  I would guess that running Firefox or Chrome browsers must be a struggle.. as they are Ram Hogs

 

I found this on the Ubuntu Forums regarding Gedit Crashing   http://ubuntuforums.org/showthread.php?t=2263450  which may be the same problem..

Cybbermouse reported that she got "no files found" rather than "command not found," so I'm guessing that journalctl might have been adopted by Ubuntu in their 14.10 distribution after all.

I found this on the Ubuntu Forums regarding Gedit Crashing http://ubuntuforums.org/showthread.php?t=2263450 which may be the same problem..

Nice find. That might explain why Gedit is crashing, as it's not particularly RAM intensive.
