Debian Configuration :: System Hang On X Logout

Jun 23, 2015

If I shutdown from X the system hangs and I have to yank out the power cord. Same on logout.

ctrl+alt+f1 hangs for a few minutes and then starts a terminal; which does not respond to the keyboard.

There are no tty.conf files in /etc/init .

But inittab looks normal to me and includes tty (1-6)

Executing init 6 from a terminal in X will reboot the system

I was thinking this might be a dbus issue, but I am not sure. I also understand some recent issues exist with SysRq sequences. May be a video card issue,,,

Other than normal package upgrades the only changes were a recent change from a VGA to HDMI cable. I can't see why that would matter

Linux Lugh 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u2 x86_64 GNU/Linux

Debian Configuration :: XFCE Logout Doesn't Completely Logout Of System / Solution For This?

Oct 17, 2010

As a normal user I have activated the functions of the Quit applet, i.e. Logout, Shutdown and Restart are active buttons. I am able to restart or shutdown, no problems. But when I use the Logout button I don't get logged out, just returned to the login shell & I am still logged in as my user. I don't have a display manager installed and I do NOT want to use a display manager such as XDM or GDM. How do I get the Logout button to actually logout the user? It appears I am only getting logged out of the x-session, but I want complete logout.

Debian Configuration :: Fglrx System Hang On Screen Suspend

Aug 18, 2015

My system is hanging on screen suspension... And its not the usual hang on "sleep" or others similars, it will happen by only having the screen on stand-by ( eg xset +dpms)...

If I leave for a while the screen will shutdown as expected but computer will completely hang after an indefinite time, it will not respond to outside connections and the will be spinning faster than usual...

Only workaround is to have the screen power save option disabled, in my case, on the KDE settings...

I have tried the most common solution to have "nomodeset" as a kernel option to disable mode setting, but this doesn't seem to work...

Also tried to forcebly reproduce the issue with Code: Select allxset force dpms standby/suspend/off but nothing happens like that...

This issue also only appears with the fglrx driver, open-source works well.

Debian Configuration :: Remote Connection Timeout Error After 10 15 Second Hang

Jan 18, 2011

I have a windows 7 box and a debian 5.0 box connected to a linksys wrt300n router. I can access the linux box from windows 7 through ssh. I used to be able to access the linux box from outside the LAN, but when I was messing with the ssh port configuration (at least I think this was what happened), i lost my ability to connect. I tried writing a new sshd_config file so that it is much simpler:

Protocol 2
PasswordAuthentication no
UsePAM yes

I tried directly connecting the linux box to the internet to rule out a router firewall issue that i was missing. iptables -L yields nothing, as I have since rebooted the machine since messing with iptables rules. But still, when I try to ssh in from outside the LAN, I get a connection timeout error after a 10-15 second hang.

Debian :: System Hang When Shutting Down Printer?

Jul 8, 2011

I have a strange problem on my system. When I turn off printer, system hang. Gdm/X exit and I can see a terminal screen with a lot of info (but I can not capture it, except taking a photo). I must press reset button. It's not all times, but at least 50% I shutdown printer. I was looking logs and I can not see any relevant. Maybe this (copy some sections of /var/log/messages, remove other not revelant):

Jul 7 19:43:34 dcr64 kernel: [341172.052076] usb 1-8: new high speed USB device number 7 using ehci_hcd
Jul 7 19:43:34 dcr64 kernel: [341172.185255] usb 1-8: New USB device found, idVendor=03f0, idProduct=4412
Jul 7 19:43:34 dcr64 kernel: [341172.185260] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=3


Sometimes I turn on printer to get a photocopy and turn off later, and system hand, so, it's not necesary to print or scan to get this error.

Debian Installation :: System Appear To Hang At Different Points During Install

Aug 28, 2010

i reached step six where it states "6. When the root and swap partitions are formatted the base installation will begin. Note that your system may appear to hang at different points during the install but it hasn't. Just be patient." I have been staring at a blank blue screen with this blinking cursor at the bottom for 30 minutes and i was just wondering how much more "patient" will it take. for some system details. the system is clean / fist time run and anything installed on it.

Debian Hardware :: Microsoft Designer Bluetooth Mouse System Hang When Pairing

Aug 1, 2015

Just picked up a Microsoft Designer Bluetooth Mouse.Whenever I try to pair it, my system hangs and I have to hard power it down. The mouse is Bluetooth 4.0, but my Bluetooth connectivity is provided by my Intel Wireless 3160 card which does support Bluetooth 4.0.I'm using Blueman as a front end, and one other thing of note is that it shows as "Unknown" after a scan.If I need to return it, I need to return it, but it seems like a good mouse and I'd like to keep it if I can make it work.

I've took this out of syslog:

Debian Configuration :: No Longer Allowed To Access The System Configuration

Jul 31, 2011

I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

Ubuntu :: Remove Panel Configuration In Home Directory - Logout And Login

May 22, 2010

I've just made a fresh install of Ubuntu 10.04. When I right-click a panel and choose "New Panel", the panel is made, but is not visible. The panel is placed on the left side of the screen, and icons on the desktop is moved to the right. Also windows does not use the full width of the screen when maximized. I've tried to remove the panel configuration in my home directory, logout and login, installing ATI drivers and running a gnome-panel command (from another post on ubuntu forums), but nothing works.

Ubuntu :: 10.04 LTS System Freeze On Logout.

May 28, 2010

My partner and I share the computer, so we are normally both logged in.

When we come to turn the computer off, one of us will log out then the other shuts down (to have a clean shutdown), but when either one of us uses 'Logout' the system just freezes, no response, nothing, have to turn the machine off via power button.

We can 'switch user' fine, and everything else appears ok but log out fails, I did try reporting a bug on this, but seems to have got taken over with people with dual screens / SLI cards, taking it over and its not the same thing.

I get the 'impression' its a graphics driver issue, I'm using the 'recommended' Nvidia driver (am at work and can't remember which version sorry).

Ubuntu :: Firefox Causing The System Logout

Nov 11, 2010

I'm running firefox 3.6.12 with the following add ons installed: Windows Media Player 10, Div X web player and Flash 10.1 r102. Ubuntu is 32 bit as is the Flash plugin. Quicktime, VLC and iTunes application detector are installed but disabled. I get recurrent episodes whilst using firefox where the entire screen goes grey/black and after a minute or so the login screen appears and I have to enter my password get back to the desktop. I suspect that this is flash related as it normally occurs after watching a few minutes of video. Disabling flash reduces the frequency of the problem but does not eliminate it.

Ubuntu :: Remove Logout From System Menu?

Feb 9, 2011

On 10.04, Lucid, I have a need to adjust the system menu for one of our accounts to remove the Log Out [Name] item. It's a rather embarrassing problem involving the nVidia driver, a laptop, a dock and dual monitors, where ending a gnome session sems to crash the video driver (or even the whole computer, I'm not sure) where I can adjust the contents of the system menu either for the whole system or for particular users?

Ubuntu Multimedia :: No Logout System Sound Since Years?

Apr 20, 2010

Since I can remember, Logout sound never plays in Ubuntu, or maybe the problem is Compiz + Gnome. A very similar problem occurs in KDE (Kubuntu), but here the problem is No Login sound.

Gnome + Compiz: Good Login sound, No Logout sound.
KDE: No Login Sound, good Logout sound.

So, what is the problem with Login/Logout sounds in Linux now? I have used the last 4 Ubuntu releases, and Logout sound never plays in Ubuntu(gnome).How could a fix that?

Fedora :: System Hang On External HD - 10

Aug 4, 2009

I am running fedora 10 on my laptop. I use a usb Western digital "MyBook" 500Gb (ext3). I am using this hard drive since more than 1 year now. Lately I run into a single problem when I read a precise file. The laptop becomes totally unresponsive and I have to manually shutdown the computer. After start-up I can find that the /var/log/message file of my previous session has grown very quickly with "[sdb] Sense Key : No Sense [current]" and "[sdb] Add. Sense: No additional sense information" messages.

I found various similar question on the web, most of the answer were hardware dependent and kernel related. I tried various kernel hoping that my specific problem would be fixed in the next one but with no success (all the kernel since fedora 10 release and two testing one: and, I don't have access to a Fedora 11 machine.

I replaced the usb cable and check that the power supply was working correctly.

I am joining part of /var/log/message and the results of lsusb (related to the external hard drive).

Debian Configuration :: The 'freezing' System Of Debian

Nov 15, 2010

How does the 'testing' version of Debian stabilize? I mean, the updates from upstream are very frequent, so if the Debian maintainers upgrade a package till the very end (for e.g if they just upgrade to 2.6.36), when will they get time to test it (so as to freeze it)?

Ubuntu :: Applications Hang And System Freezes?

Jan 28, 2011

I am running Ubuntu 10.10 on a Lenovo Thinkpad T61p with 2GB RAM. When I was on Ubuntu 10.04, one day suddenly Azureus hung at the 'loading plugin' screen as it begins. I had to hard reboot my system and it(Azureus) never worked after that so I removed it. Then after a couple of months same thing happened with Adobe Acrobat reader. As soon as I opened any pdf and started to scroll, it hung. System didn't respond and had to hard reboot. I moved to foxit reader Then I upgraded to 10.10 and now mplayer hangs occasionally if I try to switch it to full screen. System stops responding totallyn Where to begin debugging from ? I can't figure out any pattern or any way to reproduce it. I haven't tried Acrobat reader and Azureus on 10.10

Debian Configuration :: How To Remove VM From System

Jan 10, 2016

I would like to remove a specific domU (test01--pv--guest) from my machine. I am not sure how far/to what extent to remove files. Here are the files and properties it seems I should remove:

lrwxrwxrwx 1 root root 10 Jan 9 11:05 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--disk -> ../../dm-3
lrwxrwxrwx 1 root root 10 Jan 9 01:03 /dev/disk/by-id/dm-name-xenvg-test01--pv--guest--swap -> ../../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/mapper/xenvg-test01--pv--guest--disk -> ../dm-3
lrwxrwxrwx 1 root root 7 Jan 9 01:03 /dev/mapper/xenvg-test01--pv--guest--swap -> ../dm-2
lrwxrwxrwx 1 root root 7 Jan 9 11:05 /dev/xenvg/test01-pv-guest-disk -> ../dm-3

The above link to dm-2 and dm-3.

brw-rw---- 1 root disk 254, 0 Jan 9 01:03 /dev/dm-0
brw-rw---- 1 root disk 254, 1 Jan 9 01:03 /dev/dm-1
brw-rw---- 1 root disk 254, 2 Jan 9 01:03 /dev/dm-2
brw-rw---- 1 root disk 254, 3 Jan 9 11:05 /dev/dm-3
brw-rw---- 1 root disk 254, 4 Jan 9 01:03 /dev/dm-4
brw-rw---- 1 root disk 254, 5 Jan 9 01:03 /dev/dm-5
brw-rw---- 1 root disk 254, 6 Jan 9 01:03 /dev/dm-6
brw-rw---- 1 root disk 254, 7 Jan 9 01:03 /dev/dm-7

Will they be deleted automatically or should/can I remove them? How do I check the need for the other dm-? files? As indicated below, it seems like some may be duplicates.

I also found this set in /etc/lvm/archive/:

-rw------- 1 root root 2909 Oct 17 00:41
-rw------- 1 root root 2929 Oct 24 22:08
-rw------- 1 root root 2924 Oct 25 19:33
-rw------- 1 root root 2901 Oct 26 19:53
-rw------- 1 root root 2902 Oct 26 19:53

[Code] ....

Some of these seem like duplicates. This may be due to multiple attempts to build the volumes. Is there a way to determine if all of the are useful?

Anyone know the reason why a sleep( ) on a Redhat Linux OS would cause the system to indefinitely hang? It's doing this every 10 or so calls in my program and I have to press the reboot button on my computer. My program is reading from a UDP port that has messages sent to it 20 times per second. When I sleep I assume the internal UDP buffer is getting more and more filled.

Red Hat :: 5.3 Hang At INIT - Unable To Boot System Anymore

May 23, 2010

After a kernel update action, it seems that I'm unable to boot a system anymore. First off, after installing the kernel, and trying to shutdown to boot to the new kernel, the system replied with INIT: no more processes left in this runlevel. Kernel update was performed from to the following versions 2.6.18-128.el5.img -> 2.6.18-164.11.1.el5.img . The system is a VMWare virtual machine. When trying to reboot, the system passes GRUB, starts initializing and after loading the dm it stops for a few seconds at the message Waiting for new devices, show the following message:

Setting up new root fs no fstab.sys, mounting internal defaults. After this and a few other messages, it displays : INIT: version 2.85 booting INIT - No more processes left in this runlevel INIT: Id "x" respawning too fast : disabled for 5 minutes And then it just hangs. This is the output of my inittab:


The system boots into failsafe, but still shows the errors mentioned.
