Ubuntu :: Boot ... Freezes And Stops Responding To Keyboard Input - Dodgy Package To Blame?

Jul 26, 2011

My trusty 11.04 x64 Ubuntu desktop machine stopped booting up properly about 2 weeks ago - it goes through Grub and into Plymouth, but then freezes and stops responding to keyboard input either on a dark purple screen, or less often the same but with the Ubuntu logo and the 5 boot progress circles but with none of them lit up. I can hit escape early on after grub and see initialisation reports showing everything successful (other than a fail on "Automatic crash report generation") - up to a line saying "Stopping System V runlevel compatibility [OK]", at which point it freezes.

Going into recovery mode allows me to fsck the disk (which is fine, and smartctl reports all attributes as fine), fix packages (which I have done a number of times, to no avail) and boot into safe graphical mode, which works fine, albeit only on one monitor and with very poor graphics performance, obviously. As the machine was borked and everything was backed up on my fileserver anyway, I decided to nuke it and give Fedora a go (I've been using Ubuntu since Feisty and it was a good time to try something else). Fedora was fine (and worked with the default nouveau driver), but I didn't like it, so after less than 24 hours away from the fold I decided to come back to Ubuntu.

At least a reinstall should fix the problem with booting, right? Wrong! The live CD worked fine, installed perfectly, and the machine behaved itself upon first reboot - at which point I ran apt-get dist-upgrade, restarted, and blam - right back where I started. Updated vanilla Ubuntu 11.04 will not boot. Has Ubuntu released a dodgy package that has broken my x server? I don't want to have to go back to 10.10 -

Ubuntu :: 10.04 Freezes - Computer Stops Responding

Jul 5, 2010

I am using a 64 bit version of Ubuntu 10.04 on my Dell Studio. Sometimes my computer stops responding. I wouldn't say completely frozen, kinda semi-freeze. I am able to see the mouse pointer move and also when I move the mouse pointer over the Maximize, Minimize or Close buttons, the buttons get highlighted but I am unable to click on them. Alt+Tab key combination to move to another window doesn't work either. I experienced the same problem when using Ubuntu 9.10 64 bit for which reason I dumped Ubuntu then.

Ubuntu :: Microsoft Wireless Keyboard Stops Responding?

Dec 2, 2010

I have a Microsoft Wireless Keyboard 3000 v2 and Microsoft Explorer Mouse Model 1362. The biggest issue I have right now is with the keyboard. The keyboard will start cutting out and not responding to keys. As soon as the cpu load drops then all is well. I have a PS2 keyboard that I keep plugged in just in case the load stays high and I need to type something. The mouse and the keyboard have seperate usb dongles, and when the keyboard is having issues the mouse is still working great. This tells me that either the USB radio for the keyboard gets turned off, or that something on my machine is weird. I have seen the EXACT same behaviour on 32bit and 64bit linux distros.

CPU: AMD X3 720 oc'ed to 3.22GHZ
MOBO: Biostar
Video: HIS ATI 4890 (using FGLRX)
HD: Samsung 1TB 7200RPM drive
OS: Ubuntu 10.10 (tested also with Fedora 14, OpenSUSE 11.3)

Note: it happens with very little load and high load. Of course high load it happens all the time.

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:

Ubuntu :: 10.04 64bit Stops Responding?

May 2, 2010

I've been using 10.04 since just before the release candidate, currently I've installed a clean full install of 10.04 and I've been experiencing random nonresponse times with my system. I could just be sitting here reading some email or visiting a web page and suddenly the system will just stop responding.

When this happens nothing responds. No mouse, no keyboard, nothing. It's a total lockup. This problem wasn't happening with any of the Ubuntu releases before 10.04 but something with 10.04 doesn't seem to like my system. My system is an AMD X4 Phenom processor with 7GB of ram, ATI video, etc. It's a fairly nice system and this nonresponse issue is really starting to annoy me.

Is anyone else having a similar issue? I'm going to download the 32bit version and install it to see if the problem happens there too. Not sure on how to track down what could be happening as it really look like its random at this point. Pretty strange and very frustrating. I suppose if I can't figure it out, I can just reinstall 9.10 for now.

Ubuntu :: 10.04 Stops Responding For A Few Seconds?

Sep 15, 2010

I know this is the kind of vague post that people hate. But I'm having a problem. Every now and then (several times a day), my computer stops responding for several seconds.

I notice it most in Firefox. If I'm typing information in a form (like this one) on a web page, everything just stops. If I keep typing, the text eventually appears, apparently having been stored in a keyboard buffer.

But it's not just in Firefox. I have had the same problem in OpenOffice applications. Things just stop. The computer apears to "think" for several seconds, and then things continue.

After several seconds, everything is okay. So some people may say that this is normal. And while I'm no guru, I have been around computers for a long time, so I remember back in the day when this happened all the time. But I haven't seen it (at least to this extent) in previous versions of Ubuntu (or in Windows).

It's a serious problem.

what I should look at? I have a feeling that there is some setting somewhere (cache, etc.) that is set wrong.

Fedora :: Boot Randomly Hangs And Waits For Keyboard Input

Sep 18, 2010

I have a very strange problem with Fedora 13 on my home PC. When booting it just hangs at random points in the boot process. When it happend the first time, I thought the PC probably is completed frozen, but then I discovered that hitting the return button got the boot process going on again, but just step by step. That means on every boot I have to keep hitting the return button until gnome starts up, that's very annoying. So for any reason the boot process seems to switch to interactive mode somehow...

I already removed the kernel boot options rhgb and quiet to see, where exactly this happens in the boot process. But as I said, it seems to be completely random. Sometimes it's when "Starting udev", sometimes, when setting up eth card, when starting atd, and so on. It's different every time.

By the way, a similar thing happens when shutting down. It can take up to half an hour until the PC really shuts down. But it's usually going faster if I just keep hitting return after issueing the shutdown command (which actually looks a bit dull). But the PC finally shuts down at some point. That's not the case when booting up. I thought, maybe there's some kind of timeout problem. But even waiting for two hours, the PC does not startup without keeping hammering the return button

Ubuntu :: 10.04 Freezes During Boot With USB Connected KVM Keyboard And Mouse

Aug 18, 2010

I have been battling this issues for about a year now. Kind of got tired of dealing with it, but inevitably I go away for vacation or something and I lose power at the fort then the system will not come back up on its own.

Every time (100%) I power my system on with the single USB cable connected to it, my system hangs. It did it on 8.x, 9.x and all versions of 10.x. I have asked the questions before, but never get anywhere with it. Finally I have found this Forum and figured out how to ask questions Weird, I know

The system goes through the BIOS check and gets to the GRUB loader. If I do nothing, it hangs with a black screen just after it says that it is loading the kernel.

If I change the kernel commands to include the noacpi=apic or most other common fixes for what I have been told, USB, I get to the same place seemingly.

In reading through the forums and a little testing, I find that if I remove the splash and the quiet commands (obviously snicker), I am able to see where it is really stopping, but does not make sense to me.

The last informational text that appears to be processed is one of

Registered Protocol Family 1

There is nothing in the SYSLOG, MESSAGES or DMESG at all for this boot. I would assume that the system is not to a point where we can log this data

This is an AMD Phenom II x4 running 10.04 64bit Ubuntu. The USB connected device is an Avocent KVM 4 port with Audio and USB.

Ubuntu :: Mouse Stops Responding For A Moment

There seems to be an issue with my mouse. This issue is present whether working in Ubuntu 9.10, or Windows 7. The mouse stops responding for a moment or two every little bit. At first I thought the problem came from power management, but that doesn't seem to be it. I tried disabling hpet, and a host of other things. Nothing works at all, and yes, I tried using another mouse. my system is nice and new

Ubuntu Servers :: Server Stops Responding After A While?

Apr 6, 2010

I recently decided to install Ubuntu and I went through all of the steps to set up a subversion server using svnserve. It all works except for one thing: it stops responding to remote computers after a while.I have the server on a 4 port wireless router/switch in my dorm room. I set up port forwarding so that the server receives all traic over the correct ports. The subversion server AND the default http server on Ubuntu work fine always as long as I access them from a computer connected to the switch in my room.The problem is that if I try to access it from anywhere else, it won't respond at all unless it has been accessed by a computer on the switch recently (something like 30-60 minutes). So to fix it I have to go back to my room and access it from a computer on the switch. Then it will work from anywhere for another 30-60 minutes.

Ubuntu :: Evolution Stops Working/responding?

Dec 6, 2010

I'm having some trouble with Evolution. I have set up two IMAP accounts and ne POP account. Whenever I leave Evolution running for a while, work with something else and then get back to check my email it won't show new emails for the IMAP accounts. In the "progress bar" at the bottom it shows:Ping server XXX (0% complete) Checking new emails (0% complete) nd this seems to go on and on, I've waited for abt.0 minutes for it to finish pinging and checking for new emails but it doesn't stop. The P account works fine. If I however close Evolution and then start it again it immediately check and show new email in the IMAP accounts. Is there any solution to this

CentOS 5 Server :: 5.3 Network Stops Responding?

Apr 24, 2009

after a update to 5.3 from 5.2 via the built in updater the system stops responding to visitors from the outside, http that is, but heres the odd part, if i say run firefox on the server the connection works also for some reason if i'm on the network with my own computer the connection seems to stay open but as soon as i stop using these the server seems to drop the conenctions, but as i said as soon as i go via my comp to the server via say ie it works right away.

this i tried yesterday:did a cold boot to see if some update had problems and actually needed a reboot even if the updater didn't say, after it started the connection seemed to be open for a good while, and not untill this morning from a outside source the connection is droped again, not been on my comp nor logged on on the server today yet.the install only has on it what i got from the dvd, and as far as i know it has all the updates on it since 5.3 came out.my network is built up like this:

CentOS 5 :: Nautilus Stops Responding With 100% CPU Use In Some Directories?

Jan 9, 2010

I was wondering if anyone else has noticed the following behavior lately. Sometimes, when I enter a directory, during the generation of thumbnails nautilus freezes up with 100% cpu use. It has to be killed. It will then happen whenever I try to enter that specific directory with nautilus (although access with Konqueror or command-line is fine). Turning off the previews allows nautilus to enter that directory (usually... once even that didn't work). If I create a new directory and move all the files from the troublesome directory into the new directory, I can enter the new directory with nautilus and it works fine, even with thumbnails turned on. I can even rename that directory to the same name as the problematic one had and it will work. Long ago this behavior used to happen very rarely, then it seemed to be fixed, and now it is happening again but fairly frequently.

I was just wondering if anyone else has experienced this and, if so, do they know what is causing it? A simple solution is to turn off thumbnails but I'd prefer another solution.

Server :: Apache Stops Responding To HTTP Requests Every Few Days?

Dec 28, 2010

I've had a VPS running Ubuntu 9.10 x64 server, hosting 3 websites of mine for a few months now. This problem has been happening for a while. Every once in a while, probably every 2 or 3 days, I'll wake up in the morning, and apache won't be responding, no web pages will load. /etc/init.d/apache2 status, reports that apache is functioning properly. Every time I simply have to restart the daemon and things run fine for another few days.

I thought maybe it was a memory issue, so I lowered the MaxClients in the prefork module from 50 to 30 a few days ago, but the same thing is still happening. My VPS has 512MB of ram, burstable to 1GB, and according to Virtuozzo, there was only one night of high traffic where I even came close to that soft limit. I've checked my syslog, and there's absolutely nothing in there about apache. I've checked apache's error.log as well, and there's nothing in there that would indicate a problem either.

Software :: Virtualbox On Sid - VM - The Screen Goes Black Then Computer Completely Stops Responding - Needs Hard Reboot

So I'm in need of VM'ing a couple OS's to keep from repartitioning and dual booting my desktop. The first I'm trying to boot is a 64bit version of windows (have XP and 7 disc, trying XP for now) as I need to convert some of my work's ancient programs that still use DOS functions.

I choose Virtualbox over VMware just for the sake of VB being in the repos. Install and initial config went fine, but when I try to start (run) the VM the screen goes black, then the computer completely stops responding and needs a hard reboot.

first I thought it had something to do with shortcuts in compiz but no. I changed the keyboard shortcut for "run a terminal" to something wild like CTRL+SHIFT+ALT+N and it still doesn't work. That command is not doing anything... Can i add my custom commands to keyboard shortcuts and how?
