Ubuntu :: Hanging Desktop Sometimes - Requires A SYSREQ Reboot To Restart It
May 11, 2011
Any time i try to start my computer from a cold state (off for 1+ hours), the first time i start it, it hangs and requires a SYSREQ reboot to restart it. When it hangs, all the window decorations disappear and the background vanishes. The main menu opens, but click on things does nothing. clicking shutdown only brings up the normal shutdown window with the text replaced with squares.
Thought it was my hdd (i/o errors and for some reason the HDD remounts r/o at this point), but e2fsck shows no issue.
Thought it may be an IRQ conflict, so i enabled MSI on all my PCI Devices.
Thought it was the 'green' aspect of my WD Drive, so i set the spindown time to 5 hours using hdparm config file. startup messages printed to screen confirm it is working.
Also, due to the numerous hard resets, the system is detecting a 'previous i/o error to the superblock'. Should recovering the SB from a backup be beneficial?

There's a strange problem, after installing ubuntu 10.04.1 using wubi.
The installation goes fine in Windows, unpacks to an empty 15gb ntfs partition. After restarting to complete the installation, it would'n find the grldr but fixed that by copying over the wubi* files installed in C:.
Now the problem, the boot screen shows for a few seconds, switches to the default ubuntu wallpaper, the mouse cursor is there and working, and that's it. The installation doesn't continue, the keyboard won't work; Also I've tried all the additional options the installation offers when it asks to press Esc.
The system:
Wubi installed size: 15gb
32bit Ubuntu 10.04.1
4gb installed ram
nVidia 9800gx2
Using ubuntu for a month on my netbook determined me to add it to my desktop so I hope this gets fixed

I have been having a small problem since I upgraded from Jaunty to Karmic, whenever I shutdown or restart, root password is required due to multiple users being logged-in.
I have run ck-list-sessions, however I can not trace where (or what) session 5 is.
Code:
Since I have MythTV installed and there was a similar bug, I tried the following solution without any success: [url].

I am having occasional internet connection problems on startup. 1 out of 5 times that I start my computer, I will have absolutely no internet connectivity, can't ping my router, obtain ip. nothing. Tried re-establishing connection with no luck. Status light on my router displays a slow flash. I restart, problem solved. Not so much a major problem, but irritating at times

I just installed openSUSE 11.2 KDE via LiveCD on my desktop computer and have been loving it. The problem is that it will randomly freeze and requires a restart. I've tried booting up in safe-mode, but it still does it. Also, when it does, the screen flickers and flashes in and out before it freezes. And before anyone asks, yes, I have my NVIDIA drivers.

I recently built a computer for a friend that is only going to be used to run a network share.
The problem I am running into is that whenever the computer restarts the share, while visible, cannot be accessed by the two Windows 7 laptops in the house.
If I run 'sudo umount /media/storage' followed by 'sudo mount /dev/sda1 /media/storage' the once visible but inaccessible share is now accessible.
I do not understand why this would be. I have added the line 'usershare owner only = false' to my smb.conf file.

Im running opensuse 11.2 on Linux 2.6.31.5-0.1 64Bit, KDE 4.3.1 with 4GB RAM, Intel duo core processor with Intel graphics card. I initially had opensuse 11.1, which i removed and installed 11.2. Initially everything.Then came the problem, the system starts up fine but then after a few hours freezes, monitor powers off and it wont accept commands from the keyboard or mouse. Meanwhile the lights (caps lock, numeric and scroll) on the keyboard blink. The power light is still on and i can hear the hard disk turning.
I have to forcefully turn the power off and restart but can freeze again after random periods.I do lengthy and demanding computations and its common for the PC to run for weeks without turning it off.

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:
****Before Connect****
jake@jake-laptop:~$ sudo iwconfig eth1

I have a home server running Debian Wheezy ( 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u6 x86_64 GNU/Linux). I have a Realtek RTL8111/8168B NIC and an Intel 82574L. I saw while searching Google that both cards have this issue. I'm currently using the Realtek card for LAN connectivity. If I try to tranfer large files via SAMBA or have any kind of load on the NIC, my system freezes and requires a reboot in order to restore connectivity. The error message from kern.log is:
Nov 26 02:41:53 golgotha kernel: [ 5178.413329] AMD-Vi: Event logged [IO_PAGE_FAULT device=0a:00.0 domain=0x0021 address=0x0000000000003000 flags=0x0050]

Everything runs fine until I try to do a large file tranfer or have multiple users connected.
lspci returns:

Also, I've rolled the driver back to rtl_nic/rtl8168f-1.fw and currently have that installed, but the error still occurs.

I installed ubuntu 10.10 and everything works perfectly, but whenever I go to shutdown/restart, after showing the ubuntu logo (just like when you log in), the logo goes away, and it just hangs/freezes there.
I've tried waiting even for 10 minutes, but nothing. It there anything I can manually edit for it to just shutdown? If it helps here is my PC...

...and to be specific the WLAN module is a Ralink RT3090.

As the title suggests, I have to restart alsa everytime I restart the computer. Obviously that's pretty annoying.
So once restart I normally do:
Code:
sudo alsa force-restart
It will then give me a few warnings (see screenshot 2) and then unload and reload all the drivers and everything works fine.

I have a weird problem. When I restart/reboot, the computer restarts (I see the BIOS, Grub, etc., sequences) and goes right back into my desktop session - no login required. This is not the behavior I want.How can I make it reboot to the login screen?I'm running Ubuntu 10.10 Maverick

By trying to install opensuse 11.4 / 1 the installation hungsup at a late level. After rebooting the system, the configuration goes on. When finishing the installation on that way, there are no menus so you can to simply nothing. The problem of system hanging exists also with version 11.3 final release but after rebooting the configuration goes on and when finished, you have the menus.

running Ubuntu 10.10, generally with no probs. After the upgrade to 10.10, and several updates, I still have a problem. Namely when ever I re-boot, which now more often than I'd like, due to a machine failure. It starts, but accross the network can't "see" tux, pop to root term, and
Quote:
root@tux:~# stop smbd
smbd stop/waiting
root@tux:~# start smbd
smbd start/running, process 3682
and that fixes it. Whats wrong with the startup script?

Come across with a situation where all methods of shutdown result in a restart/reboot? I've tried commands:
- shutdown
- halt
- poweroff
.. with various parameters, nothing works. The laptop seems to power off, but after a sec it restarts/reboots. I've Googled high and low, but there's very little on this topic. Maybe it is specific to the current kernel in Wheezy? I'm not suspecting a harware failure, since this was not happening with Windows installed.
This happens on me with Wheezy on a HP Elitebook 8530w.

I had been manually starting my wireless network with "sudo iwconfig wlan0 essid "my wireless router id". The network would start and work flawlessly for weeks at a time. I can't ask my wife to find the essid in the terminal and then start wireless manually when I'm not here. She hates and fears the terminal. So I downloaded gnome network manager for a point and click interface on gnome panel.The network would start fine but shut down after anywhere from one to six hours. It would then refuse to restart manually or otherwise. I completely uninstalled network manager and tried wicd instead. The same basic problem is happening. The network will restart if I reboot the computer. My system:
Desktop computer acting as proxy server for the internet. Internet connection is by a dial up modem. This computer uses a wireless pci card connected to a dedicated hub. This is for file sharing via nfs. The OS is ubuntu 9.10. My wife's computer sharing the internet using a proxy to my computer. File sharing via nfs and a wireless card. Also running ubuntu 9.10. This same basic system worked flawlessly under Ubuntu Hardy.My desktop was updated recently with new hardware which created the need to move to Ubuntu Karmic. Some hardware was too new for hardy to deal with.

I am having slight issue with setting up file sharing. I have a windows 7 pc and hp proliant microserver running. I have a raid array which I am using as a share for storing music, pictures etc. When I reboot the debian server I can't connect to the server from the windows 7 PC (I have mapped a network drive) until I go on to the server and restart samba with /etc/init.d/samba restart - then everything works fine. I can ping the server with both ip and hostname but the network drive does not connect - this is straight after a reboot. Is the /etc/init.d/samba restart doing something differently to when the server boots? I have read several posts relating to printer sharing issues which point to samba not starting before cups so I am wondering if samba is starting before some of the relevant networking services.

I'm using RHEL 5 with the Enhanced Security. Using the suggest NISPOM Red Hat documented settings (located on the system; copy - paste) I have managed to audit failed file open accesses however, this setting only retained if I enter it at the command line (/sbin/auditctl -a ). If I reboot the system or restart the service all my -a (not -w) located in the /etc/audit/audit.rules are not retained.

When I set up Twin View in the nVidia config tool (as either a regular user or as root), it only lasts until I log out and log back in (i.e. restart x) or until I restart the machine. In either case once I get to the log in splash screen again, it is only operating on one monitor, and when I log in I have to reconfigure in order to get Twin View back. How can I get the configuration to stay?
More info below:
I just installed opensuse 11.2 on an AMD 64 bit 3800. It has an nVidia GeForce 7600 GS card. I installed the nVidia driver no problem and can access the nVidia config app as a regular user or as root. Both access via KDE run level 5. That is, in a GUI desktop environment. I set up Twin View fine (it is kind of clunky process, but it does recognize my monitor resolutions fine) and click apply and I get the twin view I want. I clicked on save x config but all it does is bring up a file save dialog with a 'browse' button. Isn't this supposed to automatically know where the X config file is and update it? If it isn't, what file am I supposed to look for to save over? I looked in /etc/X11 and only found the following files:
./rstart/config
./xdm/xdm-config
./xdm/SuSEconfig.xdm
./fs/config
./proxymngr/pmconfig

I have a 10x2tb disk array that i'm trying to build into a single software raid 5 i have tried this 2 times now the first it made it to 58.7% and the machine locked up and the array would not restart after a reboot. On my 2nd try all was looking good until about 50% i noticed that the speed dropped in 1/2 and that ksoftirqd/2 is taking up a lot of cpu (about 90%) the md0_resync and md0_raid5 are also taking 60-90% when the build started they took 7%. when i do a dmesg i see a lot of the message compute_blocknr: map not correct.
For a little info on the physical setup this is running on an Atom 510 with 2GB of mem the drives are connected to an addonics 4-Port RAID 5 / JBOD SATA II PCI Controller using the sil3124 chipset. I'm using 2 addonics 5X1 SATA Port Multiplier connected to the controller to get the 10 drives attached. All drive show up and don't seem to have any issues. I'm running a fully updated as of 3/20/10 version of centos 5.4
I will let this continue to run over night but i expect it to be locked up by morning if it follows what the last attempt did.

I had Compiz Fusion working and wobbly windows and the likes, but after installing some updates and VirtualBox, Cairo Dock and AWN to see which one I liked, Amarok and Qlix for Zune, I restarted. Now when I open Cairo Dock there is a black border around it like transparency is disabled, no desktop effects, and I am unable to activate them because I get a no drivers found message. I don't see why this is happening considering it was working from the get-go
I have an ATI Radeon x1300, which is on the legacy list so I don't think there are drivers for it anymore that work with newer versions of Ubuntu, but I don't understand why it worked before.
My system specs:
Dell Dimension C521
2.5 GB RAM
AMD Athlon 64 3200+
ATI Radeon x1300
Ubuntu Lucid Lynx 32 Bit (Is it worth upgrading to 64 bit?)

I have a PC running 10.10 Gnome 2.32.0 Kernal 2.6.35-24-generic-pae, i686
I am using /dev/sda3 on my primary hard drive (200Gb) to run my Kernal I have all my documents stored on a second, 500Gb hard drive: sdb2
I have noticed in the past 2 days that I delete or move files and folders, but when I reboot they re-appear. I have ALSO noticed today that the Templates folder within my Documents folder, I have a copy of my /etc/ directory... It is a copy and I am wondering:
a. How it got there
b. Could it be the cause of the problems
c. How I remove it.

Working with an old desktop that had been running 8.04 Update failed so I installed from a LiveCD. Dual boot with XP. System runs great off of the CD. After installation of 10.04 and a restart, the system worked well. Tried lots of stuff off the Gnome menus. Restarted and booted XP. That worked too.
On my next restart I selected Ubuntu from the grub menu and the system gave me the sign in requester. I signed in but the desktop never appeared. All I got was the background and a mouse pointer.
Right clicking the mouse brings up a 7 item menu that includes items for creating a folder, creating a file, ....., choose a new background. The menu works. If I click create a file an icon for a new file appears on the screen. Clicking on the icon brings up a window running gedit. Choosing the new background item brings up a window with candidate new backgrounds. I have no idea how to get the gnome desktop back. The sign in screen has a bar at the bottom that shows Gnome is the default session setting. Booting into XP continues to work.
I've tried changing the GRUB_CMDLINE_LINUX_DEFAULT= line in the /etc/default/grub to add nomodeset. That didn't help.

I just recently installed Kubuntu desktop onto Ubuntu and I don't have any shutdown or restart options shown in KDE, but they show up in Gnome. I initially installed Kubuntu using GDM instead of KDM and switched to KDM when I saw that my Gnome taskbars overlayed my KDE taskbars. To switch from GDM to KDM I used the following command:
sudo dpkg-reconfigure gdm
After enabling KDM the terminal suggested a command to configure KDM, however I can't remember the command. I ran it and I got a message that KDM was already configured.

I have a fresh install of Ubuntu 10.10 on a home server. I can connect to it using vinagre from another computer just fine. However, if I restart the server I can no longer vnc to it because I need to log in (start a gnome session). Is there a way to do this using just vinagre? Do I need to install another vnc server on my home server? The problem is that I don't want to carry a monitor from another room just so I can log in and start a gdm session if the home server gets restarted.

I have a Lucid installation which I've imaged and pushed to several computers on the network at my office. The system authenticates network users with Active Directory using Kerberos, and mounts NFS shares from a Lucid server downstairs using pam_mount. It all works quite smoothly most of the time, but I get desktop icons in Gnome only on the first login. If I log out, then log in as a different user (local or network, it doesn't matter), the desktop icons are all gone. Everything else looks normal, and I can open a Nautilus window and view any location on the hard drive just as expected. If I use the run dialog or a terminal window to executekillall nautilus the icons are restored. This works whether any instance of a file browser window is open or not.
I have noticed similar, but far less consistent, behavior with gnome-panel. Every once in a while the panels will fail to appear when I log in, but I can restore them withkillall gnome-panel When I run either command, everything works fine until the next login. If I reboot the machine, I get everything back again for one login. Then the desktop icons will disappear, and I have to kill Nautilus and let it restart in order to get them back. I expect I'm missing something important here, but I don't know where to look next.
