Ubuntu :: Programs Randomly And Frequently Stop Responding?

Mar 19, 2011

programs (especially Firefox, though I haven't used other programs much) stop responding rather frequently without warning and after some time they just start responding again. Apt-get also takes ages to unpack stuff when I'm upgrading/installing something, that might be related. According to top there is barely any cpu usage at all during these freezes. I had this issue on a stock Lucid install. When Maverick came out, I tried that one, and the issue still existed. On a fully upgraded Maverick system, it's still there as well. Windows works without a hitch, as does Ubuntu running under a VM on windows.

System specs:

CPU: Phenom 2 x4 945 @ 3 GHz
GPU: Radeon HD 5770 with fglrx
4 GB of ddr3 ram
Motherboard: Asus M4A89GTD PRO
Hard drives: 2 WD 1.5 TB drives running on a fakeraid 1 array

Ubuntu :: 10.10 Freezes Randomly - Keyboard And Mouse Stop Responding

Feb 4, 2011

I have installed Ubuntu 10.10 on other machines before and have not experienced this problem. Occasionally, the system will lock up. They keyboard and mouse stop responding (my keyboard status lights no longer respond, but my optical mouse light is still on). I can ssh to the machine, and it seems to work as normal. I kill processes that are open on my desktop through ssh, (i.e., Firefox), and I notice when I switch back, I still have the same frozen image on my screen. I have looked at the following files to determine any issues with the GPU:

Note: I use debian testing.GUI very frequently completely breaks for me, it looks like this:URL....It usually happens after a short freeze or after going back to GUI from TTY (which doesn't display because of a known Nvidia proprietary driver issue).And sometimes my laptop goes into sleep state by itself while it's being used. This is lenovo ideapad z510 laptop, with intel+nvidia GPU (nvidia Optimus). To use nvidia GPU I use bumblebee.

Ubuntu :: Put Frequently Used Programs In Ram For Faster Startup Time?

Jun 12, 2010

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

Ubuntu :: KDE Dolphin Stop Responding On NFSv4 Share

Apr 4, 2011

I just started to use NFSv4, but Dolphin seems to have problems with it. For example if I copy something from local partition to the nfs partition dolphin stops to response. I cannot launch another dolphin or browse the current dolphin. After copying is completed the dolphin starts to work again. I also have cifs partitions via samba, but with those I don't have this problem. Something wrong with my NFS configuration maybe?

Code:
/export 192.168.0.0/24(rw,fsid=0,no_subtree_check,async,no_root_squash)
/export/alpha 192.168.0.0/24(rw,no_subtree_check,async,nohide,no_root_squash)
/export/beta 192.168.0.0/24(rw,no_subtree_check,async,nohide,no_root_squash)
/export/gamma 192.168.0.0/24(rw,no_subtree_check,async,nohide,no_root_squash)
/export/delta 192.168.0.0/24(rw,no_subtree_check,async,nohide,no_root_squash)

Slackware :: Windows Stop Responding To Keyboard (13.1)?

Jun 1, 2010

I upgraded to 13.1 from 13.0 a few days ago. I have a Toshiba Satellite L3655D that I leave on constantly. Twice now, I have woken up to windows (urxvt and firefox) that don't accept keyboard input. I can paste into them and they respond, clicking is fine, but the keyboard either barely sends or is completely ignored - if I tap a bunch of keys, one or two might go through, eventually. New windows work fine, so I have to replace everything I have open.

edit:I switched to XFCE for 2 days and the issue didn't appear, but my other laptop with the same fluxbox settings also did not have any problems. I switched the original laptop back to fluxbox (and happened to upgrade the ATI drivers around the same time) and haven't had it happen since. If this happens to you, try restarting X.

Ubuntu Servers :: Stop Responding: Goes Into An Automated Scanning Mode

Jul 14, 2010

I just installed ubuntu as a learning tool. It was going fine until the next day after the install. This happened on two reinstall of ubuntu server 10.4. All was installed was lamp, squid, privoxy, tor, shorewall, and phpmyadmin. I have added 3 websites to the server.

Today, I noticed my internet stopped responding on my other pc which is linked to my server for internet access( privoxy). When I turned on the server, I noticed the screen was purging out random lines. I don't know what they mean, but it was a never ending series of lines filling the whole screen. To stop it, I ctrl+c. Some of these lines read usb, keyboard, mouse, etc. I am guessing the system went hay-wired.

When I reboot the machine, it did it again. This time I don't have the cmd prompt. I didn't know another other way to properly shutdown so I just cold reboot the machine. The next time it booted up, all seems normal like it always have been. My sites, internet is working.

I probably didn't provide enough info to diagnose this behavior. As mentioned before, it happened the first time I installed the server and it is happening again with the same applications installed.

Edited: It happened again. Some of the lines I could make out are these.

Code:
Bug: unable to handle kernal NULL pointer deference
Kernal panic-not syncing: Attempted to kill the idle task!
Error panic occured: Switching back to text console.
The server froze at this point.

General :: USB Devices Stop Responding When A New Device Is Inserted?

Oct 4, 2010

I'm running archlinux & just recently started having a problem where ALL USB devices will stop responding for a second when a new USB device is plugged in. dmesg doesn't provide any hints.For example, I've got my music on an external HD & it will stop playing for like ~30 seconds if plug in my camera or gamepad...This issue only seemed to start after my home partition was erased & re-created, though I don't see how these two issues could be related.I've been running a custom kernel (2.6.35-rc6) for the past few months, and that hadn't changed to spur this issue. Thinking it may have been something weird with the kernel, I even switched over 2.6.36-rc6-mainline, yet this did not remediate the issue.

Ubuntu :: KDE Apps Stop Responding To Mouse/keyboard But Plasma Still Works?

Jul 30, 2011

Hey folks. I'm not sure how to describe this properly but periodically Kubuntu 11.04 will stop responding to my mouse and keyboard EXCEPT that Plasma, or what I assume is Plasma, still responds to mouse events. I can launch and exit the desktop cube and desktop grid but can't access my panels or any application controls. The only fix I've found is to do a hard power cycle.

Does this behavior ring any bells for anyone? This is the last hurdle I've got between me and using Kubuntu 11.04 full time on my Samsung RV515.

Ubuntu :: The Mouse And The Keyboard Will Stop Responding And The Screen Sometimes Get Divided Into 4 Smaller Quadrants?

Jul 15, 2011

My ubuntu session will freeze and stop working. For example, the mouse and the keyboard will stop responding and the screen sometimes get divided into 4 smaller quadrants of the current screen.The only thing I can do after it freezes is reboot the machine.Would anyone know what is causing this?Also, I keep having to move my optical mouse from the usb slot into a ps/2 slot.And the same thing with my keyboard. I have 2 keyboards, so I can plug in the old ps/2 keyboard instead of the new usb keyboard. (the devices keep flipping)My machine is an AMD 3400 with an Epox mobo. Nothing like this has ever happened before, and I have been using ubuntu for more than 4 years without any problems.

Fedora Hardware :: Keyboard / Mouse Stop Responding; Replugging Isn't Registered?

Jan 23, 2011

Today my keyboard and or mouse repeatedly stop responding some minutes after boot. Currently the mouse stops responding after a few seconds of movement immediately after boot. Yesterday I used the machine most of the day, yet this issue didn't arise. Today I used it for a few hours before the issue developed. I did a full system update from the fresh install yesterday night. It's therefore possible that this issue has arisen as a result of the update, and that today the onset was delayed for some reason.

Earlier today I had the same problem with the keyboard. I replaced the batteries thinking that this was the cause. Now it looks like both keyboard and mouse are affected by the same problem. When the mouse stops functioning and the keyboard remains active, I unplug the mouse and replug it in, but it still does not respond, and only the unplug, and not the replug, are detected and logged in dmesg. I noticed ever since I installed Fedora yesterday that plugging in new usb devices after boot did not result in them being recognised, and that if I unplugged a mouse or keyboard and plugged them in again they would not work (requiring a hard reset). Currently the machine isn't usable as I cannot use the mouse for more than a few seconds. I haven't tried a PS2 connection, and currently I have keyboard access.

Hardware:

Fujitsu LZ945230BH1 USB Mouse
Microsoft Arc Bluetooth Wireless USB Keyboard
Running Fedora 14.

I haven't tried PS2. My keyboard and mouse appear to be working again (25 mins and still responsive).I unplugged all USB devices except for the keyboard, mouse, and wifi dongle. This appears to have solved the problem. Other devices that were plugged in were a USB to SATA external HDD caddy (powered off), and a serial USB connection to a Sheeva Plug computer (mini server). how I can use all my USB ports in future without this issue arising?

Ubuntu Networking :: Machine Will Suddenly Stop Responding To Connections While Still Remaining Partially Connectible?

Jan 2, 2011

I have a strange problem where my machine will suddenly stop responding to connections while still remaining partially connectible. Here's an example sequence of events I have taken (numerous times). If anyone can spot something else I should check or has seen these symptoms before please let me know.1) System is using an Edimax 7318-usg, Ubuntu 10.042) Wifi connection is working, with power management turned off (iwconfig)3) Signal strength does not cause the connection to drop (confirmed with router logs)4) When in a ssh session on the problem machine suddenly the ssh session is dropped "host is down"5) When I attempt to re-initiate ssh it fails, no route to host...6) Pinging it fails, accessing a webpage hosted on it fails, all access fails7) The machine I'm pinging/sshing from still has a good network connection8 ) I check my routers DHCP leases, problem machine still has a valid lease.

9) Router still shows problem machine in routing & arp table & shows active traffic going to and from (I checked the routers states and bandwidth monitor for this)10) I try sshing and pinging the problem machine from the laptop on the local network, it still fails, no route to host, wtf?11) I go to the problem machine physically, wifi connection is up with decent signal12) ifconfig indicates it still holds an IP address13) I open a browser on the problem machine, any webpage loads fine14) I ping the laptop from the problem machine, ok15) I ssh from the problem machine to my laptop, it works16) At this point I ssh from the laptop to the problem machine, sometimes it works sometimes it fails(it seems that pinging/sshing the laptop FROM the problem machine sometimes makes it connectable again).

17) Usually if I wait a while the problem machine will randomly become connectable again at random intervals18 ) The only reliable way to make the problem machine connectable again is manually reconnecting it to the wireless network19) I tailed auth.log ufw.log, etc. nothing suspicious disallowing my ssh connection20) dmesg shows nothing unusual, as far as I can tell, just some activity negotiating WPA keys and suchBy looking at the timestamp for the WPA negotiation and cross referencing the router bandwidth monitor I can tell the WPAnegotiation doesn't make it drop the conectionSo that's it, lol.

Ubuntu :: Quicksynergy And Synergy Randomly Stop Working?

Jun 3, 2010

I'm using Quicksynergy on my desktop (Ubuntu 10.04) computer as the server and Synergy on my Laptop (Windows XP) which is right beside my desktop.Everything works well for a while, but randomly seems to stop working. When I look into the problem, it seems that its with Quicksynergy on my desktop.I find that I have to quit Quicksynergy and open the system resources application to kill the Synergy daemon (or whatever it is) that Quicksynergy uses.Restarting Quicksynergy after killing the daemon fixes the problem as my laptop always reconnects perfectly fine.Does anyone else have this problem in Ubuntu? I'd like to get this fixed so I don't have to keep killing the synergy process and restarting Synergy.

Ubuntu Networking :: WIRED Lan Dropping Randomly In 10.10 / Stop It To Do So?

Dec 27, 2010

Lspci:
05:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12)

My wired LAN keeps dropping randomly, average of every 30-60 minutes. Fresh install of 10.10 from iso, Been installed for about 4 days now, just performed system update today, no change.

My router actually completely resets itself. You can watch the lights power off and recycle doing their POST. Absolutely no problems in windows 7 dual boot configuration.

I am no downloading anything, not streaming, not doing anything actually. My computer is completely idle (save for BOINC) and all of a sudden my phone loses the wireless connection which lets me know that my router just reset.

Ubuntu is actually doing this, my wireless stays up indefinitely in windows. Once the router resets, it does automatically reconnect without a PC reboot, but why is it resetting my router?

Ubuntu :: Programs Close Randomly - Result Been Crashing Most

Feb 17, 2010

I've never seen this before, but for the past few days whatever I'm working on has had a tendency to close out with no warning. Just in the last two days evince, empathy, and eclipse have closed randomly. Since I use eclipse constantly and as a result it's been crashing the most I went ahead and started it from the command line. Here's the output I get when eclipse closes:

[code]...

it appears to have something to do with the "decorator," but disabling compiz all together doesn't fix it. I'm running Ubuntu 9.10 64-bit. The issue seems to have started shortly after installing a triple-core processor - but I'm not sure that's related.

Ubuntu Multimedia :: Volume Levels Jumping Randomly / Stop It?

Jul 7, 2010

I am currently troubled with a very annoying problem - the volume level of the PC is jumping higher and lower at random intervals. It makes listening to music very difficult, as at times the music can go from just right to overly loud, just to fall right down so that it is hard to hear. I've only noticed this problem in the past few weeks, and I can definitely say it wasn't an issue in 9.10. This is a fresh install btw, not an upgrade.

Some details:
Using motherboard sound, Realtek HD Audio, iirc. Below is the output of lshw, with the irrelevant parts cut out.code...

Ubuntu Installation :: Controller Receiver Stop Working Randomly

Nov 11, 2010

I installed Ubuntu as well but was still using the windows loader. I eventually installed Ubuntu Studio when I got another HDD (which is where I installed it). Don't ask me how I did it. As of now no loader automatically pops up. It acts as if there is nothing to boot from. However I can hit f12 and chose which HDD to boot to. On one it comes up with the Windows loader w/ Vista and Ubuntu. I can chose Vista and it works just fine. However if I chose Ubuntu it starts going a lil nuts and restarts. If I chose the other HDD it boots up Grub w/ options of Ubuntu and Ubuntu Studio. Studio works (which I'm currently on) and pretty much the same thing happens as before when I chose Ubuntu. So if the 2 OS's that I need work (Only really use windows for games) then what is the problem? I know its a little bit annoying trying to remember to hit f12 and having to chose your OS again after that (and of course the extremely annoying vista startup times). Some other things in both Studio and Vista don't want to work like they should. This is about the only thing left that I could think of that may have something to do with it. My wireless card+an old wireless card I found won't work w/ either.

Yet they both work on other computers running Vista and/or Ubuntu (not studio). I seem to always keep having display problems on both as well (dual monitors and graphics both). Even on studio I have to restart it sometimes to even get it to let me go fix it. My wireless controller receiver (for games) will stop working randomly and need to be unplugged and plugged back in. I also have problems with Studio recognizing SD cards and DVD/CD's. I am not sure much of anything can be done aside from wipe and fresh install on both. Bad thing is I don't have my other computer with me and can't afford to buy a 1TB HDD right now.

Software :: Xubuntu Programs Randomly Closing

Nov 27, 2010

I'm running Xubuntu 10.10 via USB on a Dell Latitude D505.Wireless card is a Netgear WPN111 and I'm using ndiswrapper to make it work.

My problem is this:when I open any web browser and try to navigate to a page, the whole system freezes for a few min before crashing to desktop.Using Task Manager during this time reveals that processor usage jumps to 100% and stays there until the program closes.I've tried Xubuntu on another, faster machine and it was fine.
From this I conclude that it's related to the hardware, and I think it may be some hardware protection feature operating.

Software :: USB Keyboard And Mouse Randomly Stop Working In Fedora 12?

Jun 17, 2010

I'm running Fedora 12 on a Shuttle SN78SH7. Updates are all current from the Fedora repositories. I'm using the Nouveau driver for the Shuttle's on-board Nvidia graphics adapter. At random intervals (1 to 5 times per day), my USB keyboard and the buttons on my USB mouse stop working and the desktop freezes (i.e. GKrellm graphical data stops updating, partially painted windows don't complete). However, I can still move the mouse pointer around the desktop. This only seems to happen when I am actually using the computer from the console. It has never happened while the system was turned on, but not being used.

When the mouse and keyboard stop working, I can log in from another computer via ssh. Once the computer gets in this state, the only way to fix things is either to reboot remotely using ssh or to cycle power. I've run low level hardware diagnostics - everything checks out OK. This computer only has USB and firewire inputs. No PS2 jacks.

Ubuntu Installation :: Karmic Koala - Slow Jerky And Has Odd Freezes Like Windows - Applications Randomly Stop Working

Nov 7, 2010

I had been happily on Jaunty Jackalope until they stopped supporting it so I took the forced upgrade and it's HORRIBLE!

I feel like I'm back in Windows land. Within an hour of my first load I had my very first Ubuntu total-lockup. Just like Windows. In the 18 months I'd been using Jackalope I had not had a single crash. Not one.

It's slow, jerky, and has odd freezes. Just like Windows. Applications randomly stop working and die. Just like Windows.

Is there any way to fall back to Jackalope or is there any hope of them fixing Koala? 'Cause this is wretched.

I see there's another version out there...10.04.01.LTS. I'll try that. It can't be much worse.

Server :: Deadlock In NFS4 / Shared Servers Suddenly Stop Responding And Cant List It From Debian 5 Server?

Jan 4, 2010

I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:

ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying
Dec 31 08:16:33 ma25555 kernel: [1200289.815378] INFO: task java:9702 blocked for more than 120 seconds.
Dec 31 08:16:33 ma25555 kernel: [1200289.835249] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
code....

I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)

There are 3 other servers that are running Debian 4 and are working fine.

Ubuntu :: Opening File Manager Endlessly Creating In Programs Bar. Can't Stop It?

Mar 8, 2010

When I turn on my computer I am greeted by an unending stream of "Starting File Managers" appearing in the programs list. This cannot be stopped, though none of the file managers actually open. They just sit there filling up my programs bar and wasting my cpu slowing down computer. It also means I cant upon my own folders, or see what programs I have open.If I run terminal, type xkill and click on one of the buttons in the programs list, that kills them all, and I can see my programs again for a bit, until it fills up again. The panel disappears and appears again, with all the spawning messages gone and any other programs I have open remain there. Its just the randomly spawned "Starting File Managers" that don't come back.

My CPU fluctuates. Its around 60% to 90% load, when it should be idle, but is instead opening all these windows.When I view the processes the most CPU intensive (when I sort) is Gnome System Monitor at 6% and then Gnome panel at 5%,gconfd-2 is as around 2%, compiz.real, dbus-deamon hover around 1%. And everything else is generally at 0%.So somewhere, a hidden process is using about 70% of my CPU load. Which isn't shown in system-monitor. Maybe because its an admin process and I can only see simple user processes. I dunno.There is something else though. I have a process with no name appearing, its blank. And it keeps disappearing and re-appearing. So you can hardly select it hard enough to kill it. I managed to kill it once and it said error, process (large number, 10,000 or 100,000) does not exist. So can't be killed.When I do an xkill the console writes:

Code:
anthony@Anthony-Acer:~$ xkill
Select the window whose client you wish to kill with button 1....

[code]....
