Elzo Valugi's questions

I am getting some abnormal behaviour lately from my Ubuntu 14.04.4 LTS Desktop machine. With no apparent reason or failure, all program close and I get logged out. I have also noticed lately a lot of WebGL chrashes in my Chromium and Chrome. I have no idea if is some hardware or software failure, although the fact that is not a full restart, but only a logout makes me think is a software issue.

I was looking at /var/log/syslog and I have this logs since last restart which does not point me to a specific error:

I have done a distribution upgrade from 12.04 to 14.04. Although it finished and things are running I have some issues:

• system does not recover from suspend mode, I have to restart
• the multiscreen feature is missing, I only have 1 screen
• at startup I have some apport and gtk-root system errors, for which I can only find supressing, not fixing techniques.

When I do this I get this error

$ sudo dpkg --configure -a
no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory

Any suggestions?

I have this hardware problem, my UPS battery beeps a lot when using Ubuntu (not so much on windows), so I am thinking that it may be a interrupt problem or a power surge of some sort. The strange thing is that is happening even when I do a mouse scroll, or play a video on full screen or other strange seemingly unrelated events.

Any suggestions? I can post some configs if you think they can be useful.

I have read a recommendation which was stating that after installing one should remove some packages from the default Ubuntu installation, in order to have a more secure server. What are your recommendations for removal?

This is kinda strange.

The router is set fine and I can see it from a Mac and from 2 mobile phones. Is WEP protected and not hidden or other tricks, as it comes from the box. My Ubuntu is 10.04 on HP Pavillion DV1000.

When I try to connect from Ubuntu, it does see other networks (10 or more) but not my own. I've tried restarts, ifconfig up/down, rfkill block/unblock wifi, installing b43-fwcutter and nothing works.

I would appreciate any suggestions. Thanks

I had tried to install Ubuntu 10.10 near a Windows7 in a 64 system. The installation was suppose to be 512Gb left for Win and 512Gb for Ubuntu. The installation hanged and on restart windows sees only his 512 partition. When I try again to install Ubuntu I only see the windows partition.

How can I recover the lost partition and install Ubuntu there?

I am trying to unzip a 7zip file from the command line like this, but I get an error with using e or x parameters. The file has only 1 .dat file inside. I get the following error.

valugi@valugi-desktop:/$ 7z x /var/www/site/data/7zip/eu/
Processing archive: /var/www/site/data/7zip/eu/file.7z
can not open output file file.dat
Skipping    file.dat

Sub items Errors: 1

I can open the file if I am opening it with the File Roller desktop application, but I want to use the command line, as I want to integrate this into a PHP script.

How can I find out what is generating this error and how can I fix it?

Thanks

I am getting a file with a faroese name and trying to save it in a PHP script:

2010_08_Útflutningur.xls

In Ubuntu 10.04 LTS is saving it as:

2010_08_�tflutningur.xls (invalid encoding)

I've installed and run utf8-migration-tool, but with no effect.

Is this an Ubuntu error that I can fix or I just have to give up and modify the name in php?

Is there a document which states what is the acceptable charset for a filename in Ubuntu, or what are the encoding specs?

Thanks
