I have a problem with nautilus thumbnails since a few days. I checked they are indeed generated in .thumbnails, but all I got in nautilus is the "loading.." icon instead of the thumbnail, for all kind of files (pdf, image, video..) + a high cpu load.
I really don't see what to look at here, didn't found any trace of error in several logs/debug tool like gdb (and btw does nautilus have log abilities?)
I don't know which change could have triggered this (it used to work fine), maybe adding the i386 compatibilty with "dpkg --add-architecture i386" ? (I did this a few days ago in order to install acrobat reader)
Also I've been copying all of the home folder files from my previous ubuntu account to the new debian one, maybe I broke something in the process ?
hint0: thumbnails are displayed fine under thunar
Solved due to this post: [URL] ....
I just did:
Code: Select allln -s ~/.thumbnails ~/.cache/thumbnails
and my thumbnails are back

Is there a way to show or count how many CPU instructions a particular process is using or uses?
In my work we develop a web application and I'm responsible of maintaining the web server.
The app lets you handle data online so each client that uses the web application has a folder associated to it, where his data is stored. (/var/www/html/test) for example.
The idea is to get how many CPU instructions the httpd process for that particular folder is having. Is there a way to do this?

Running lenny with compiz/xfce4 and it seems to only affect a few things but I notice it mostly with google chrome. Whenever I open a new window it pops up behind chrome. This is very annoying. Chrome bug or config problem?

I use ssh via KDE 4.4.3 konsole to connect to a 2.6.28-18-generic Ubuntu SMP machine,on which I use vim 7.2 and screen 4.00.03jw4. Within a screen session, the background color persists on the screen session even after closing vim. I dont know if this is a konsole or bash or screen or vim colorscheme problem.

I recently installed Debian 8 with the Xfce Desktop Environment. I don't like the background in the login screen and want to change it. After some Googling I discovered that the path to the background is stored in the file /etc/lightdm/lightdm-gtk-greeter.conf.
Unfortunately, whenever I change the background field I'm left with a black background during login. (Yes, I triple checked that I spelt the path correctly). Does the login background have to meet some criteria I don't know about, like being a certain resolution?
EDIT: Here's the content of /etc/lightdm/lightdm-gtk-greeter.conf:
Code: Select all#
# background = Background file to use, either an image path or a color (e.g. #772953)
# theme-name = GTK+ theme to use
# icon-theme-name = Icon theme to use
# font-name = Font to use
# xft-antialias = Whether to antialias Xft fonts (true or false)

A few weeks ago I have installed Debian Jessie on KDE Desktop Version. I have a problem with the Display Manager Kdm, if i log out session the monitor turns off (DVI No Signal), the only option that I have it's forced shutdown or reboot via power button. I try another DM lightdm and this works fine. But i liked to know why log out session crash on Kdm.
Adding : TerminateServer=true at the end of /etc/kde4/kdm/kdmrc (Section :[X-:*-Core], solve the issue.

When I start a second X session using startx --:1, (as either my normal user or root), it goes straight into and LXDE session (Debian's default, I think). Once LXDE is started, there is no applications menu (only run and logout). How do I get it to show the full application menu that my regular user can see when I log in from GDM3 normally?

To use most of my Kali applications, I want to be able to log into an X session as root. I know it is generally a bad idea and I don't want to do it as a rule, but it is useful for penetration testing (e.g. nmap and its GUI don't have most of the useful options when run as a regular user).
So how do I get GDM3 to allow me to log in as root? Currently, if I type in the user name "root" and log in, it just takes me back to GDM3. Could it work to add root to my user group (I really don't want to add all kinds of security holes)?

I recently installed debian 8 stretch with xfce. Since the first time I boot, I have problem starting my X session: from lightdm I always attemped 2 or 3 times before it login (it returned me on lightdm prompt after a short splash screen).
Now it stopped working: the only way I can start xsession is running startx as root. When I try as user it starts the "splash" and return me to the tty with this error message:
Code: Select allServer terminated with error (1). Closing log file(EE)

and this the .xsession-errors:

I try to reconfigure Xorg but the Xorg -configure command result in another segmentation fault.
I think that the problem could be related with old configuration (when I install this version of debian I maintain the /home partition and my previous OS was debian 7 with xfce).

What is the Failsafe Session Type that you can select from the KDM login screen supposed to do ? With Squeeze RC1, if I attempt to log in to a failsafe session, I am returned to the KDM login screen. This does not seem very failsafe to me but then I am not a desktop expert. With Lenny (5.0.7), I get a single console window, which, I guess, at least gives one a chance of fixing whatever may be stopping the normal KDE session from starting.

I installed jessie from a beta/rc shortly before release on my MacBook Pro 13 Retina and have kept it up to-date with apt-get dist-upgrade. Rcently gdm3/gnome-session have stopped working together. When I log in the screen goes black for a couple of seconds then goes back to the login screen. This happens with "System Default", "GNOME Classic" and "GNOME", but not with "GNOME on Wayland". However, Wayland seems to have some other issues. I haven't tried an alternative dm yet, eg lightdm, but the GNOME desktop does work when started with startx.
I've just used journalctl to get logs of what gdm3 and gnome-session were doing at the time. After booting I waited until the clock reached the next minute (19:55) so I'd know at which point in the logs I'd hit enter on my password. I'll post the gdm log separately in two chunks because the forum server doesn't seem to like text attachments and they're too long for one post.
Log from gnome-session:
Code: Select all-- Logs begin at Thu 2015-05-07 19:54:06 CEST, end at Thu 2015-05-07 19:56:41 CEST. --

I have an app I've developed in Qt 5.3.1 that has display problems when using 3D accerelation in VirtualBox using Debian Cinnamon. It seems to happen with Cinnamon in any Linux distro I've tried. Once I boot into Debian Cinnamon, how can I stop my Cinnamon session (I think I must start with Ctrl+Alt+F1) , then get a straight X session to run my app without Cinnamon, with 3Dacceleration in VirtualBox?

I did an installation of amd64 testing with KDE 5 three days ago, and I noticed that my session is not restored upon login. I have this option checked at my kde system setting.
A quick search led me the next bug+patch: [URL] ....
(See also [URL] ....)
I did notice that files in ~/.config/session/ are created, but apparently not read upon login.
I tried to send a reply to the relevant bug 796062 but the email bounced back.

I know of terminating a command with & and then moving it into the background by pressing Ctrl-Z and then bg [pid], and I also know of nohup. But say you started a process that turned out to take much longer than one expected, is there a way of pulling, so to speak, this process from another terminal screen into the background so that even if I log off from the server the process would continue?
