Fedora :: Firefox-Flash Causing System To Crash

Jan 14, 2010

So this just started a few days ago... maybe 7 at the most.

I am working along, and screen goes black, or just freezes... the lights on my laptop start blinking and becomes everything becomes unresponsive.

I have noticed it is usually when I am Using Firefox and Flash content. I have also noticed it happens when using Deluge, but it usually takes 5 minutes to kick in.

I am using firefox at the moment, but I am sure if I load up a ..... video, it will lock up on me again.

Fedora :: F15 Gnome Tweak Tool Causing System To Crash

Jun 23, 2011

I've just installed F15 over the weekend, and since then I've been having stability issues - primarily it seems to be related to gnome 3 (I've used fedora since its early days, and have never had such stability issues in the prior versions). Basically, when I use gnome-tweak-tool to make a modification, the system crashes; and I have to completely shut off the unit (unplug it) for it to even boot up properly. Today, I tried to change one of the options from its default, and now the very top (black bar) won't show.

I'm in the "File Manager" mode and can see the "Computer", "home" and "Trash" icons. I can move them about; and click on any of them to open. But once they're open nothing else works (clicking on any of the directories, etc, has no effect). I can ctl-alt-F2; but that's the extent. I deleted the .gconf and .gconfd directories (suggested in a different thread on a similar issue), but that didn't change anything. How do I bring back the default gnome 3 bar at the top?

I rebuilt my user account from scratch (that was the fastest approach for me). Nevertheless, gnome-tweak-tool does crash (for example, each time I turn on "File Manager"). This is clearly a bug. I'm using nvidia GTX 480; the problem might somehow be related to the card/driver. I definitely spoke too early I logged out of my account; logged back in, and the top bar is gone again and I'm left with having to deal with this again.

Ubuntu Networking :: 2 NICs Causing Very Slow DNS Lookups?

Jul 9, 2011

I'm running Ubuntu 11.04 and I'm really new to linux. My problem is that whenever I try to browse a site I notice the website loads very slowly because it takes a long time to do lookups. I installed Ubuntu with an onboard NIC and later switched to a PCI NIC (Dlink DGE-530T). Although I disabled the onboard NIC in the BIOS, it doesn't help. Could this conflict in configuration be a problem? My download rates are fine, its just lookups that take really long ( upto ~ 10 seconds). I know the PCI network card is fine because when I jump to Windows 7, lookups are normal again (~ 300ms). At first I thought about installing the sk98lin drivers for the PCI NIC but I saw a couple of places where people have mentioned that the skge driver that comes along with the kernel is better.

I have tried a system wide as well as Firefox disable of IPv6. Here is my /etc/udev/rules.d/70-persistent-net.rules
# PCI device 0x1186:0x4b01 (skge)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:01:14:eb:39", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x10de:0x0373 (forcedeth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:3e:19:ed", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
The interface I want to use according to the listing above is the one with the MAC - 00:24:01:14:eb:39.

I tried removing one of the entries in the file above and rebooting but it still didn't work. Here is a look at my /etc/network/interfaces
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static

Ubuntu Servers :: Iptables Causing Slow Ssh And Name Lookup Errors

Jan 24, 2010

Why would this iptables cause this mail delivery error? I think it's to do with dns lookups not being routed properly... if remove the last rule, mail works fine.

ssh is also very slow to connect when the last rule is enabled.

postfix mail error:

Jan 24 11:32:18 xxxx postfix/smtp[15065]: 9F2162C519: to=<xxxxx@hotmail.com>, relay=none, delay=1005, delays=965/0.01/40/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=hotmail.com type=MX: Host not found, try again) iptables

Ubuntu :: Modprobe, Framevuffer, Udevadm, And Blkid Causing Slow Bootup In Lucid?

Sep 1, 2010

my brother's computer is pretty slow, but was working fine with ubuntu karmic, but I decided to finally upgrade him to lucid the other day, and recently his bootups take, at worst, 10 minutes,when in karmic it took way less. It just sits on a blank screen (not even a blinking cursor)

His pc's specs are:
1.4 Ghz processor (single core)
on-board graphics (no graphics card)
two hdd's one 80GB and one 150GB (the 150GB is split into 3 partitions)
465.7MB of ram 4.1GB of swap

I've attached his bootchart and it seems that Modprobe, Framebuffer, udevadm, and blkid are taking the most time to load, but I dont really know, i'm new to linux. Also how do i disable bootchart now that iv'e used it. p.s Heres he same bootchart just in case the one attached gets shrunk by ubuntuforums [URL]..

Fedora Networking :: F14 Samba Server With Slow Write Speed

Aug 4, 2011

I had a F14 samba server working flawlessly now for a quite time. Unexpectedly about a month ago the write speed slowed down around 64kbit/s and that's really slow. I haven't changed any configs, only updated the server. I've troubleshooted this from many angles:
-It is not a network issue because sftp writes are good.
-It is not a RAID1 issue because write speed from another directory (locally) are good.
So basically samba is the only thing left.

Here's example from smb.conf:
comment = My share
path = /mnt/RAID_share
writeable = yes
browseable = yes
writelist = +smbuser

Here's a snip from logs today:
[2011/08/04 09:04:27.509273, 1] smbd/server.c:267(remove_child_pid)
Scheduled cleanup of brl and lock database after unclean shutdown
[2011/08/04 09:04:47.526336, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown
[2011/08/04 09:17:57.634660, 1] smbd/server.c:267(remove_child_pid)
Scheduled cleanup of brl and lock database after unclean shutdown
[2011/08/04 09:18:17.635196, 1] smbd/server.c:240(cleanup_timeout_fn)
Cleaning up brl and lock database after unclean shutdown .....

There's a restart that is not software related.

Debian :: Total System Freeze / What Is Causing It?

Jun 16, 2011

I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.

When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

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 Multimedia :: Video In VLC Causing System Lock Up?

Apr 18, 2011

I have an intermittent and very irritating problem. I have a desktop PC with Ubuntu Lucid installed that I use primarily for watching films using VLC. Every so often (seemingly at random) around half way through the film the whole thing locks up - the video freezes, the audio skips (like a stuck record) and the system is unresponsive - the only cure is a full restart with the power button. Im at a loss as to how to try and diagnose this issue. Is there a log somewhere that might have the info after I reboot?

Usefull info on the system:

- AMD processor - 64 capable but running 32 as I wanted to avoid issues.

- grpahics is via an NVIDIA Geforce FX5500 (PCI interface NOT AGP)

- Restricted NVIDIA drivers installed and working

- Also useful to note that this problem occured when using an AGP ATI Radeon 9200 (using the standard open source drivers of course). In fact the problem was worse with the ATI - the frequency of lock ups is less with the new set up.

Slackware :: Console App Causing System To Hang On Shutdown?

Jul 14, 2011

I have been looking for a lightweight bandwidth monitoring app and came across bmon. It does what I need. However it has an interesting way of exiting.

when it is running and you close it down it ask you 'Really quit (y/n)' and does not shut down. I am used to just right clicking on my desktop and selecting 'leave' when it comes to shutdown time.

A few times now the laptop hangs on shutdown if bmon is open. I guess it is due to the app asking if it should shutdown. Is there a way to disable the app asking or alternatively nuke it for sure with some script on shutdown.

I could search the relevant konsole running the app and go thru the steps to shut it down but sometimes I am in a hurry and it doesn't feel like the way to go anyhow?

Ubuntu Multimedia :: Skype Causing System Audio To Stop?

Apr 28, 2010

I am using ubuntu 9.10, but I also noticed this with 9.04 on a different laptop. Sometimes when I am using skype, for no reason and after no particular event the audio for everything in the system except for the skype video will just quit, and sometimes the sound doesn't even work for the video either. Buttons don't make their sounds any more and I can't play music or hear audio on flash videos. By can't play music, its weird because the music player (amarok) will just scroll through my entire playlist really fast like it can't play any of the songs.

To solve the problem, I have to shut down skype and firefox, but I'm not sure whether I can just shut one of them down without having to shut down the other. My audio settings in skype are all set to pulse and it is adjusting the mixer levels automatically. This problem has persisted across two laptops and two versions of ubuntu (9.04 32 bit and 9.10 64 bit), so I think it's about time I finally asked how to fix it.

Ubuntu :: Natty Browser Randomly Causing System Crash

Jul 3, 2011

Whenever I'm browsing the web on one of my natty machines, I'm subject to periodic reboots that leave nothing in the syslog. Here's the two constants I've discovered thus far.

It only happens when I'm using a browser (plugin?).
It doesn't matter whether I'm in Chromium or Firefox.
It doesn't matter whether I use Unity or Gnome 2.
This happens every 2-3 days from what I can tell.
This problem is not power related because I've tested it with and without an UPS present.

The computer does a full reboot without any shutdown procedure.

The configuration of this computer is as follows:
Intel i3 2100
ECS H67 Dual Nic
Haupaugge Dual ATSC Tuner
8GB 1333MHz (MemTested)

The browser plugins are as follows:
Flash 10.3r181
VLC Multimedia Plugin (compatible Totem 2.32.0)
Windows Media Player Plug-in 10 (compatible; Totem)
DivX Web Player version
QuickTime Plug-in 7.6.6

Debian Multimedia :: Multiple Monitors On Laptop Causing System Freeze?

Mar 18, 2010

I'm having some trouble hooking my external flatscreen monitor up to my Toshiba Tecra's docking station and having Mint (or Debian) be happy with it. The laptop uses a widescreen monitor but my external is a 4x3; I wonder if this is causing problems. Of course, it may just be the Intel 82801G graphics adapter.et things up properly in the Display Preferences config window (I'm using Gnome, btw) but when I hit apply, the system locks and I have to hard boot. I've never set up a linux box with multiple monitors before, let alone multiple monitors that require different resolutions.

Ubuntu :: USB Disk - Slow Transfer Speeds And Slow System?

Apr 17, 2011

Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!

When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!

This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.

Fedora Security :: Slow - No System Updates ?

Oct 4, 2010

My system went for three days w/o a software update... Is this normal(anyone experiencing this?)...?

It seems like to me.. Fedora 13 has a longer update interval than Fedora 12.. I remember back in Fedora 12 I get security updates like every other 12 hrs.. (I know as with security patches the less the "better"(in some way))..

But I am still concerned.. security updates has been slow for me.

Fedora :: Slow Working And Hanging The System Unreasonably?

Dec 9, 2009

I installed Fedora 12, 64 bit on my Dell Latitude D820 laptop with Core2 Duo processor(7200 speed) and 2 gigabyte Memory.

I have updated the yum. I have enabled the rpm repositories.

It is very weird that my system suddenly works very slowly and hangs. every time I login after a while the CPU usage goes up to the end with out any reason!

Before this I had installed Fedora 12, 32 bit and I had the exact same problem.

I have installed Fedora 6, 7, 8, 9, 10 and 11 on my laptop before and I had non of these problems with them.

The interesting point is that after hanging my system works constantly slow even when I restart my system! It is slow even in booting the BIOS and start up and choosing the kernel page!

The only remedy to get rid of the slow working for a while is to Shut down the system completely and turn it on again. Restarting do not make it work normally just shutting down makes it normal for a while.

Fedora X86/64bit :: Slow Internet On X64 FC12 System / Speed It Up?

Jan 11, 2010

Does any one have a way to speed up the internet on Fedora 12? I have a dual boot system with Vista x64 on the flip-side, and my wireless connection there is just fine. But when I get on this side, it goes back to the dial-up days (yes I said the DU word). yum updates seem to be just fine, and e-mail seems to be fine. just firefox is slow. And now that I put the x64 Flash in (thanks to leigh123linux), with that working too it seems even a little slower again.

Fedora :: File Transfers (cp, Mv And Rsync) Slow System Tremendously

Aug 24, 2011

When ever I transfer large files using cp, mv, rsync or dolphin the system will slow down to the point that it's unusable. It will sometime hang completely and not accept any input until the file is transferred. I have no clue what could be causing this problem but I know it shouldn't be happening.I am using Fedora 15 ( with KDE 4.6. have a Phenom II 955 processor, 6 GB of system ram and the OS and swap file is on an 80 GB SSD. Copying files in the SSD doesn't cause any problem, but moving files between my other two large HDDs causes the extreme slow down. Using htop I can see that my system load jumps to between 3 and 4, but my RAM and CPU usage stays low during the transfer. Here are two commands that take about 10 mins to run and make the system unusable while it's running. It usually transferring around 2-20GB worth of data during the transfers:

cp -a /media/data.1.5/backup/Minecraft/backups/* /media/data.0.5/backup/Minecraft/backups/
rsync -a /media/data.1.5/backup/ /media/data.0.5/backup/
/media/data.1.5/ is the mount point for a 1.5 TB internal SATA drive, and /media/data.0.5/ is the mount point for a 500 GB internal SATA drive.

Software :: Slow Transfer From SAMBA To Win7?

Aug 30, 2011

I've done this a million times, so sure it is something simple. I just set up a file server with three drives. One is small and faster that houses all the system files. Then the other two are slower but larger (WD Green: variable 5,400-7,200 RPM) drives in RAID0 then encrypted using Blowfish 256-bit. Hence the performance double then hit below in the buffered reads.

Debian-Server-023 ~ # hdparm -tT /dev/sda
Timing cached reads: 1650 MB in 2.00 seconds = 825.44 MB/sec
Timing buffered disk reads: 234 MB in 3.02 seconds = 77.41 MB/sec
Debian-Server-023 ~ # hdparm -tT /dev/md0

Debian Configuration :: Access And Connecting To SAMBA Are Too Slow

Mar 29, 2016

Let me introduce myself, my name is Carlos Alegría from Chile and I'm System administrator for a educational Institute. We use samba+ldap, for login accounts and file sharing but we not use samba with PDC.

Long time ago at the 2009 year, I was Installing the same system and this worked perfectly. But on our summer the hard disk of server has broken, so i was need installing all the system again. So the problem is with SAMBA, when i connect to the network resource, this is to slow, and when i try transfer files are slow.

My sistem is on Debian 8 Jessie and the Samba Version is 2:4.1.17+dfsg-2+deb

Code: Select all[global]
   workgroup = LABORATORIO
   netbios name = Shinigami
   server string = debian
