Ubuntu :: 11.04 Randomly Logging Off - May Be Related To VLC?
Jul 9, 2011
Having some trouble with a new install of Ubuntu 11.04. I use it for work, so I do tend to run quite a few programs at a time. Namely Pidgin, Firefox, Thunderbird, Chrome, Osmo, LibreOffice Calc, Calculator and Text Editor. Sometimes I'll listen to music using VLC. Sometimes (and I can't figure out when), I will be suddenly logged out without warning. Just BAM, black screen then back to the login screen. I've lost work from this happening.
My only clue is that it hasn't happened when I was not running VLC, but then again it doesn't happen consistently while running VLC. Also, it happened today when I wasn't running VLC but was using Calibre (along with my usual programs). Maybe I'm doing too much at one time? Maybe it's the RAM? How do I view an error log about what happened?
this is extremely annoying, the entire screen goes black, then i see the login screen.its happened on different sites so i have no way to pinpoint whats causing thisand ubuntu doesnt display anything that makes it seem like its a crash.is there any logs that would show me whats going on?
when i'm in ubuntu 9.10, i can go to any website except for netflix.com. every time i go to netflix.com, it logs me off and i'm back at the ubuntu sign in screen. I am using Namoroka 3.6.4. can it be a browser issue?
I am trying to add subdomains on ubuntu 9.10 desktop edition and and I am not sure whether I need to add some info.(such as 127.0.0.1 sub1.example.com and so on) to the /etc/hosts file like the windows' windows/system32/drivers/etc/hosts file. I used to use the wamp-server(on Windows 7), I needed to edit 3 files, httpd.conf, httpd-vhosts.conf and hosts. And almost every edit is made in the httpd-vhosts.conf file on wamp-serveriles should be edited? or what else should be done that I didn't mention?
I installed Mono 2.4 and I am struggling myself to remove all folders related to mono.. I didn't install from Synaptic so it's not just 'apt-get autoremove mono', I used the tarball.. how to remove all files from the installation?
I've had my share of troubles with Ubuntu before and always been able to find help just by reading the forums, but this time it doesn't seem to be happening. Basically, I think I did something stupid by trying to change the permissions on my home folder to 777. (I'm the only person who uses my computer and got sick of always having to get root permissions.) Halfway through the process, the computer slowed to a crawl and text in dialog boxes started getting replaced with empty squares.
Naturally I rebooted - or tried to. Regular boot didn't work, so I tried recovery mode, which was kind enough to tell me I had a kernel panic because sbin/init wasn't found. Here's where things got weird: I then tried to boot from my Ubuntu USB stick, and couldn't. I got to the USB menu, hit the "run" option, and after a few seconds of the Ubuntu boot screen, my monitor went blank. Actually, to be technical, it didn't just show a black screen - the screen shut off. That's as far as I've been able to get.
By the way, just before I tried what I'm now calling the chmod-of-death, I also had an update freeze in the middle. I am able to boot into Windows, and have checked my USB stick - all seems fine. Any thoughts on this? Worst case, I can reformat the partition and reinstall, but I'd rather not lose all that data.
UPDATE: Okay, so I *did* manage, after about ten more tries, to boot from the USB stick. I went in from there and changed all the permissions back to 755. Tried to boot in recovery again, and still getting the same sbin/init error - so I'm wondering now if it had more to do with the failed update than the permission change....
I am migrating my server from Kloxo (lxadmin) to Ubuntu (webmin/virtualmin), and I already had my Nameservers on my register (Godaddy) to go to [URL] and [URL] along with my IP. (I set the ttl to 60 cuz I thought that might be a problem) Now, I do a dig [URL], it gives me this output.
I've seen packets coming to my computer through a DD-WRTv24s2 gateway above port 32K several times. I have iptables (using fwbuilder locally) both places. My desktop stops the packets. But I'm guessing the problem is as I described in the title for this post. Yes?If you ESTABLISH a connection to some webpage, and you just accept ESTABLISHED or RELATED datagrams in rule 1 of your iptables, what will keep incoming TCP from that (presumably nefarious) site from going straight to your desktop like the building firewall isn't there?? If the site wants to connect to you above 32k, or portscan you, its RELATED correct? They know your IP. You've ESTABLISHED a connection.If my guess is correct, it would seem wiser to NEVER use these together. Better to ACCEPT all ESTABLISHED. And if something is RELATED, then ACCEPT it only if its the data connection on FTP or individually by service or protocol.
Trying to debug a network issue - we have problems with scp transfers to a remote host intermittently stalling. I believe it may have something to do with incorrect handling of sack / dsack TCP options. Looking at netstat -s, during a (successful) scp transfer the TCPSACKDiscard and TCPDSACKIgnoredNoUndo counters increase rapidly. This is on the client initiating the transfer to the remote server. This doesn't seem normal, but I'm having difficulty finding an explanation of what exactly these counters signify. The tcp_sack / tcp_dsack / tcp_fack options are enabled in the kernel on both hosts.
How do I debug this further? Are the counters a symptom of a known problem? It's kind of hard to google this, all I get is unrelated netstat output which happens to include 1 or 2 discarded SACKs, not tens of thousands like I am seeing. I can make tcpdumps on the client (unfortunately not the server), but what should I look for?
I want some users should be barred from login into some of NIS clients. Please help me to accomplish this. I googled it but still not very clear to me. Can you please tell me how it works. The OS is RHEL 5.
I am using KMS with a radeon 3650, KMS with kernel 2.6.33.2, xf86-video-ati 6.13.0 and mesa 7.7I am using fluxbox, and only have one transparent terminal running. I have not been playing any games(so no 3d acceleration?).My computer is getting far too hot from this. Not overheating to the point it shuts down, but the fan is going full bore, and mplayer stutters when playing a movie.This never happened when I was not using KMS, so it seems likely that that is the cause. It is definitely related to graphics, because when I exit X the temperature cools rapidly.Is this just because KMS is new and still being worked out, or is it something that can possibly be fixed?
I am doing a project related to system restore concept in linux. There i am planning to perform application wise rollback in case of failure!! Is there any way to figure out what are all the files used by an application in the system??
i have recently been having random problems with mostly firefox. the 2 most annoying problems (that work in other browsers) were: no sound on various sites, like videos and amazon mp3 previews. the mailto command would not work.
the fix is 2 part: i installed the standard release of thunderbird 3.1.1 and the firefox mailto problem is fixed. i installed the standard release of firefox 3.6.7 and sound now works fine.
additionally i have removed thunderbird, firefox and related ubuntu brandng from the package manager for the following reasons:above fixes, time and frustration involved in debug.eliminates the chronic application directory rename during updates, /usr/lib/... and softlink change in /usr/bin.allows me to keep up with t'bird and firefox security patches as they are released, i.e. immmediately.
Just when I thought I was getting my Ubuntu 10.04 system stabilized and really usable, the webcam magically stopped working. When I first installed 10.04, the webcam worked perfectly right out of the box. Tonight, I tried to start the video in a Skype conversation, and nothing. Video preferences in Skype showed no options for a camera. Rebooting the machine didn't help.
The one relevant thing I can think of that happened between the last time it worked and tonight is installing a number of updates. I'm not sure how to look up which packages were installed when -- I'm happy to run commands if someone can provide them.
Unfortunately, I don't remember how it was configured before. Since it was working, I didn't look at /dev to see where the camera shows up. At the moment, there is no /dev/video*. Clearly the system doesn't recognize that the camera is there, but it did before.. I don't recall device specifics. I looked online for a spec sheet that would say who is the webcam manufacturer, but I can only find the resolution. Tomorrow I have to boot into Windows to do some other work and I can get hardware info then.The machine is an MSI A6200 220US; the specs seem not to be available on MSI's website anymore.
Brand new network, just installed, all ubuntu 9.10 boxes connected to a Dell 2206 dumb gigabit switch, and from there to Dlink router to cable modem. Pretty simple. ISP confirms great link out and inbound,
However, http requests can sit for 20-30 seconds (sometimes longer), before content returns, same for pings.
Some thought it might be MTU-related. What is best MTU setting 1500/1492/ ?
I need some piece of software that follows the requirements below. So here's the scenario:
1. I need some piece of software that will allow me to edit related articles in a wiki-like fashion. I will be the only one editing this "wiki" though.
2. I need to be able to do searches/queries on the wiki content in a very flexible but also very concise way: - The usual search for an expression in all articles or only some category(ies) but also: - Wiki links to other wiki pages based on configurable criteria, e.g. articles belonging to some category(ies): I mean something like right-clicking would open a sort of database form to perform a query that would use the said link as expression but would only be run after you'd chosen your other criteria. - If anyway possible, do the above for any selected text on the page you were watching...
3. Ideally this would be one single application of course. But I'm perfectly alright with coupling two or even more together as long as they do integrate with each other flawlessly.
I was expecting that notify-OSD bubbles behavior to bring the app displaying the notification, when you click on them. But in my case, when the mouse pointer enters the bubble, it fades out a little, and when I click on it, nothing happens.
Is that normal? Why doesn't a click bring the related app to front?
Is there any way to quickly remove multiple related packages from the command line instead of having to enter the name of every single one? I am trying to remove OpenOffice from my server running 10.04. It would work nicely if I could get a list of packages without line breaks, such as the list displayed by aptitude when upgrading. That way I could just paste the package list into the terminal. However, "aptitude search 'openoffice'" dumps a long list on many lines that cannot be used that way.
I had a hard time deleting Wubi from Windows 7.To make sure it all got off, I want to manually check and delete anything Ubuntu and/or Wubi related from my registry, since I did a full install
how, and if, I enable 3Dnow, and other CPU related features?
I'm not having any problems or anything to that effect. I am only curious. Is this something that's automatically done? Is this something I must do during compile and install of applications?
haunted@haunted-desktop:~$ sudo grep flags /proc/cpuinfo flags: fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow
If this is something I must enable manually per application, then for example, if I wanted it enabled for FlightGear, how would I go about doing that?
I just blindly install 'java' in GNU/Linux Debian SID -- so I could use it as a plugin for iceweasel -- Unfortunately, things didn't work as expected. I was used to Debian's APT to take care of things for me as it had done for more years than I could remember. (Being a desktop user/programmer and a beginner system network admin). I want a clean install of java plugin for iceweasel. So I want to remove completely all java related packages --
How do I know which is which and if they are safe to remove without affecting any other part of the system? Now, to install -- what do I need to install in order for iceweasel to have the Java plugin and let java work as it should? I prefer from the Debian package. But if it doesn't work, I'll accept JRE from the java site and install them myself.
In the processing of reinstalling VirtualBox, I found this：2.6.35.6-48.fc14.i686.PAE/source -> /usr/src/kernels/2.6.35.6-48.fc14.i686.PAE/ ，but this folder don't exist.。 I try to relink the ln as source -> /usr/src/kernels/2.6.35.9-64.fc14.i686.PAE , but VirtualBox still get problem with the kernel. Since VirB works fine with other 2 kernels, the solution for this is not quite needed, but I just wonder why this happens. See below. I don't know why these two folder contain different version of kernels. Anybody get an idea?

11.3 installation appears to be completely unusable for mission critical workit's running/freezing on a Toshiba a300 laptop, intel 965gm gfx, using the drivers that where installed by 11.3whenever the unstoppable screen/monitor saver kicks in, it freezes the machine irrecoverably.same as: 11.3 kde constant lock upsthe unstoppable screen/monitor saver has been a pain in the neck in 11.2 too, is it possible to COMPLETELY REMOVE any code that will make the gfx go on standby? what a pain when you are watching a movie! disabling everything obvious never worked! wtf?
I know 10.3 is old, but my main reason for using Linux is that I can build a machine and then just use it for 3-5 years without dealing with stupid degradation issues like Winblows.
The problem is that I can't access any 10.3 online respositories anymore, so package management is a big mess. Basically I'm down to manual rpm-ing. If I try to install anything with Yast, it attempts to access 10 different repositories for dependencies, all of which fail because I guess they just don't have 10.3 directories anymore.
I really hate updating my Linux all the time to the newest version, because frankly that usually breaks things.
Not sure what do to. This conundrum often makes me consider if any distributions are better in this regard. But then I don't have a lot of time to play with Linux. What started out as a hobby in 1994 is now a tool, like any OS, that I just want to work. I don't use Linux to use Linux, I use it to run programs.
I installed FC14. But when i create a VPN connection using NetworkManager, 10 seconds after VPN connection was established, vpn connection has been disconnected.In FC13, I didn't have this problem. In FC14, i use same settings used in FC13.
After building a new system I have been getting kernel panics randomly. I have been able to look at /var/log/messages and determine that either my RAID card, XFS, or something along those lines is causing the problem. It has now gotten bad enough that any heavy use of the RAID will cause it to panic and die.
There is one large file on this that I need which is not on my backups but when I try to get it off, the transfer will cause a kernel panic within minutes. What is causing the panic? Is there any way to resolve it? The RAID card is an LSI SAS3081E-R and I am using the built in drivers/modules within Ubuntu 10.04 x64 (pretty sure the kernel itself has the driver included). There is source available for the driver from LSI's site but I'm not sure if that will solve the problem and in addition to that, I can't figure out how to compile and install it. It has a Makefile already but make just complains "no targets".
