I"m a newish Ubuntu user, but have been running some flavour or other for the last 5-6-7 years. Anyway, I just recently installed Maverick and have to say it's polished compared to the last version I tried ( maybe 6? ).
I am however having a frustrating issue while surfing the web. After a 2-3 minutes using firefox, 5-10 minutes using chromium - the whole system seems to lock up solid. The mouse/ keyboard no longer respond. I've read through a few log files and nothing seems to stand out, though I may be looking at the wrong place. I plan on running some system monitors, and top when I get home to see if they show me anything. Just thought I'd come here to ask for any other things to have a look at.
it only seems to happen when im using wicd to change wireless access points several times in a short time span. i havent done anything out of the ordinary, installed packages off of sbopkg, and built my own kernel, but this happens in the stock kernel toothe following is what appears in syslog each time it happens
Code: Mar 7 13:12:14 null kernel: [ 1.714177] WARNING: at arch/x86/kernel/hpet.c:404 hpet_next_event+0x5f/0x81() Mar 7 13:12:14 null kernel: [ 1.714969] Hardware name: 3241
I have a fresh install of CentOS 5.5 on small thin client system with a 80G HDDs, 1 GB ram [URL], I have run into an issue where the system just locks up and freezes and I can no longer access it, cant ping it, cant use webmin and cant view its web pages. The system seemed to be running fine unitl I left it to do some updates via webmin as it informed me there were 118 updates. I really only use the system as a LAN captive network server, and it is currently in the testing phase for this setup. The install went on with no issues and it ran fine, but now every so often within 12 hours it just locks up and I have to reboot. kdump shows no logs so I am finding hard to work out what is going on. but have installed it on 5 of my servers 4x ibm x335 and this . I intend to use the mini server for a captive portal system displaying advertising and promotions to wireless clients.
Since upgrading to lucid, I have been experiencing regular system lockups. About once a day, my X desktop will disappear and I'll see a TTY with a few old console messages and at that point everything is completely frozen and I must hard reboot.
I have checked out various logs in /var/log and found nothing at all that indicates the system knew anything bad was happening. What is the correct approach to try to narrow this down?
My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.

I recently upgraded to 11.04 and when I browse to pages that use the flashplugin the whole system froze. So I installed the flashplugin that somehow got deinstalled and while installing the system froze again. I fixed the dpkg and then I could connect to websites using flash but nonetheless the system freezes after some seconds using any browser. I have a Netgear WLAN card that uses Windows drivers as there are none for linux. It worked alright in 10.04 for a whole long time. On my netbook with 11.04 everything works like a charm...
I have Ubuntu running on a Compaq desktop. Version 9.04 ran great but since upgrading to 9.10 it intermittently locks up. There is no rhyme or reason to the timing. Sometimes it is immediately after logging in but usually it is after the system has been running awhile. Sometimes it happens when I'm actively using it and sometimes when it is idle. It has never happened at the login screen, no matter how long I leave it.
Note that it is not a complete lockup. The mouse cursor moves, but no longer functions (i.e. you can't click anything). The keyboard does not work at all. For example Ctrl-Alt-Backspace and Ctrl-Alt-F5 do nothing. Disconnecting and reconnecting the mouse and keyboard does not help. Also, I can still access the system over the network using SMB and SSH, which leads me to believe that X or Gnome is where the problem lies.
Here are the troubleshooting steps I have done so far. As I said I can access the system using SSH, so I logged in and ran "top" to view CPU utilization. I found no process using more than 1% of the CPU. Also I examined the messages log and found "segfault" errors related to libc (?), USB and my keyboard, so as a test I traded my fancy wireless keyboard for a generic one. That has not helped. I'm not sure where to go from here. I've examined other logs but it is all Greek to me. There are entries that sound as if they could be errors but I'm not sure and the times of the errors don't match the times of the lockups anyway.
I am on 64-bit Natty and for the first time since my install a month ago, I have had a system hang requiring a power-off restart. It happened yesterday and a few moments ago.My question is that I want to troubleshoot this myself and wonder if the activities that my system were running just prior to crashing are recorded in a log file somewhere.I used to look int /var/log.messages or /var/log/boot, but this was in the Maverick days.
I've tried searching all over the place, and I'm drowning in outdated and contradictory information. I have a brand new Netgear WiFi PCI adapter. The exact model is "WN311B-100NAS N300" The related output of lspci is
Module Size Used by lib80211_crypt_tkip 17387 0 wl 2568244 0 lib80211 14991 2 lib80211_crypt_tkip,wl

So, I know it's using the BCM4321 chipset and wl driver. Ubuntu detected this card without any trouble, and I was able to use the "Additional Drivers" application to get it running before disconnecting my ethernet.
The card works well, and is very stable until I try to download a file larger than a few MB, or try to play a video stored on my home network. As soon as I try either of those, my computer locks up hard. No error messages. Just a hard lockup that I can't get out of with anything short of holding down the power button on my case until it cuts the power supply.
I had this problem at times with 11.2 as well; I use GNOME. I have intermittent lockups when invoking the screen saver either while idle or soon afterward while using Firefox; problem seems to not show up if I do not use a screen saver when idle.
I have been having come problem, my surfing speed has gone to zero. I can download at full speed but surfing is crawl speed or just timing out. I am pretty sure it's because firefox is clogged, I just want to know is there a way to clear the clog w/o losing my settings? I fixed this before by making a new user, but I don't want to loose all my saved form's and bookmarks.
1: when im surfing the web and watchin vids....the screen appears jumpy? i think its a graphic card problem but i dont know were to find it.......or how to sort this!2: using skype i find that my mic dont work but my cam dose...when i use the sound recorder in the applications the mic works!!!3: i had a wireless symbol at the top on the panel but now its gone!!! any ideas where i can find it to put it back up there!!4:i instailed itunes using WINE but now i cant remove it due to the fact that everytime i chose uninstail it reinstalls!!? i want to remove it coz it is jumpy too!!!i aint too sure if my notebook has got to be modified to be able to use ubuntu 10.10 to the best it has to offer
I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!
I used this command to restart the networking but in vain Code: sudo /etc/init.d/networking restart
On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.
wat is the advantage of introducing softlock feature in rhel? How user/admin will be benifitted if softlockup events are occoured? on the contrary, server dies if softlock happens.We hardly can take some preventive action against softlockups, but most of the times we are not able to do anything about softlockups?
I have installed the fglrx driver from "Hardware Drivers" and it runs fine, until I launch gnome3 or gnome-shell, it then just locks X (its not hard locked, I can CTRL + ALT + 2/3 etc out) but I cant do anything else.
If I use the mesa / xorg driver its fine.
The trouble is I play one game, and I need the fglrx driver for that game, the mesa one corrupts the 3d engine
It wouldnt be a pain, but i am one of the few who seems to find gnome-shell an improvement, and I get really frustrated when it wont work.
Any idea's on what I can try, other than hopfully having a working system when ATI launches the 10.10 driver on its website (although the leaked rc had the same issue) I only recently got a ATI card so I am pretty new when dealing with the ATI cat's.
My bluetooth doesn't seem to be working,and ubuntu recognises the inernet(i mean connected to the computer by cable)but mozzilla doesn't seem to be surfing the net),and it doesnt detect wireless signals at all.I'm new to ubuntu,it works in windows so theres no internet p[roblem,and my bluetooth is fine in windows,ubuntu doesnt seem to recognise my phone or desktop at all.And how do you move file freely like drag drop save as?Is there any other way other than those terminal commands?thanx ubuntu version 10.4.Some one told me i should configure some DHCP,i have absolutely no idea of what it is( for internet)
I have a handful of openSUSE 11.4 machines that I allow users to use the GUI for web surfing and writing documents and I am meanwhile running scientific computing jobs in the background. Every now and then, someone clicks "shutdown", "reboot", or "hibernate" and ruins my afternoon.
I've searched Google and these forums for ways to prevent a normal user from shutting down the system, but so far haven't had any luck in finding a solution. I have found instructions for just about every other Linux OS, except openSUSE though. These machines are running LXDE, but my preferred solution wouldn't depend on the particular desktop solution in use.
I don't know if these are related, but I have had occasional lockups, where no input has any effect and then it shuts down, and am usually unable to resume from suspend on closing the lid.
Here are the specifics. Thinkpad x120e, AMD e-350, ATI radion 6310 graphics, Intel 320 series SSD 80 GB, no bluetooth.
The ethernet and wireless cards, as given in lspci, are
My 32-bit Ubuntu 9.10 [Karmic Koala] LTSP server has two NICs, one with Dynamic IP set by a DSL modem and the other with static IP of 192.168.0.254. I also have 4 thin Clients that boot from this server without any problems and another computer with Ubuntu 9.04 running some PHP programs with dynamic IP given by the same DSL modem. When I send requests to these PHP programs from thin clients, they all give the LTSP server's dynamic IP as their IP so I cannot trace who has sent this request to response back.
I actually know this is logical. Because the requests are sent by a program that's actually running on the LTSP server rather than the thin client. But my question is How can I run a program on a thin client with it's own IP? I also should mention that the dhcp3-server service running on the LTSP server has no conflicts with the DSL dhcp on the network and I know that the 4 thin clients get the IPs ranging from 192.168.1.101 through 192.168.1.104 from the dhcp3-server service. Because I can ping them while they're on. but /sbin/ifconfig on them shows info about the LTSP server.
I am using squid proxy server for sharing Internet in my internal network. I would like to know that how can I check the browsing history by individual users web surfing history by their IP addresses?
My problem is that I need to move a moderately complex system from an old system to a new system. The old system is a core 2 duo running on an asus p5k-se (p35 chipset) M/B, Nvidia 8500 gt, 3 x sata II hard disks, 1 x sata dvd, 1 x ide hd, 4GB ram. It runs opensuse 11.1 kde 4 as a desktop system + samba server, apache server, database server + other non-opensuse software. In addition some of the opensuse software is not the default 11.1 versions as later versions were required. The nvidia driver is from the nvidia repo. There are several file systems, some under LVM.
The new system will be a core5 760, asus p7p55d-e M/b (p55 chipset), nvidia 240, 3 x sata II HD, 1 x sata dvd, 4GB ram and possibly 1 x ide HD. This M/B also includes USB 3 & sata III. I have no USB 3 devices but this may eventually change. I have no plans for sata III and believe that it may be better to attach any sata III SSD to the sata II bus.
What I would like to do is to move the hard disks from old system to the new system. What I would like to know is, if the system is left at 11.1, is the system likely to work with the new hardware. If the answer is no, if the system was upgraded to 11.3, would the transfer of the hard disks then work? In order to upgrade from 11.1 to 11.3 using the DVD i believe I should get rid of all non-default repos. I assume that I should also get rid of anything that was installed from them, e.g. the nvidia driver and any software versions installed manually outside RPM. Also is there any default 11.1 software that should be removed either before or after the upgrade to 11.3
My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?
I am an absolutely beginner with Linux (ubuntu). I got fed up with widows and decided it was time to go. I installed (clean install from a cd) ubuntu 10.04 on my desktop. It is an hp compaq d220 MT.It looks good and feels good, well at least for a while since it keeps crashing. The screen starts to flicker, goes black, and the only way to get it up and running again is to press the on/off button until the system powers off and restart.
In System Monitor, on the File Systems tab, the "Total", "Available" and "Used" columns don't seem to add up, and the "Used" percentage doesn't seem correct either.
My config: /dev/sda1 = 80 GB SSD drive, / partition. /dev/sdb1 = 50 GB FAT32 partition of an external 500 GB USB hard disk. /dev/sdb2 = remainder of the 500 GB USB hard disk encrypted using luks.
Screenshot: The /dev/sda1 figures don't really add up well, but they're close at least (how you get "50% Used" from any of those figures I don't know!).
However, for /dev/sdb2, they're miles off: "Free" = 146.2 GiB "Total" = 409.7 GiB "Available" = 125.4 GiB "Used" = 263.5 GiB
I'm niomi and I'm the first account with sudo. I add an account, bob. niomi can get in reliably on active mode. (maybe relevant?: passive doesn't work) bob is jailed to his home directory, niomi is in ftp-special which gives her access to /. bob can't log in and his shell is set to bin/false. What could have gone wrong?
I am using ubuntu 11.04 in my home desktop. Is it necessary that firewall should be active inorder to avoid hack? I heard that we will not be given static ip address, only paid one will get static ip address that can be used for web server implementation. If my system doesnt have static address then can others access my system?
I am trying to restore my system to Ubuntu 10.10, using a system backup made with REMASTERSYS. When I reboot, I get the message: GRUB error:15 I found many threads discussing this issue, most notably here: [URL]
