View 4 RepliesHas anyone else who uses Miro noticed a very noticeable sluggishness to it lately? It's been a bit since I've used it, but opened it up today, and it's just performing at a crawl, not to mention sucking up a goodly amount of CPU cycles (process "miro.real"). I've tried the Repo version 3.5.x as well as the PPA version 4.0.3, both are just as slow and as choppy as it can be in 11.04. Any thoughts, or anyone just want to share my misery? It loves company...

View 1 Replies View RelatedWhen i installed ubuntu. I made a seperate partition so that i could copy an ISO image onto it of an up-to-date version of ubuntu. I wanted to then boot the ISO up so i could install the new version that way. I've already tried doing it through the update manager but it'll download, almost be done with installing and it freezes on me. so i figured this would be easier. However i do not know how to gain access to the other partition to copy the ISO image. Please help.

View 3 Replies View RelatedI just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

Uptime 5 minutes

As you can see, when system is "fresh" booted there are no noticeable "Extra timer interrupts". As time goes, this number seems to increase. I have tried to find out what causes this behaviour without any luck. I am not even sure if this is any practical problem, as performance seems to be more or less unaffected, but any explanation to this would be nice. Anyone else ever notice this?I am running Ubuntu 9.10 Server edition on a Dell Poweredge SC1420, 64-bit version. The server is used for web and file sharing mostly, with little load. (15 min avg. about 0,10).
After installing Fedora 6 (and probably any later version) I find that access to the add/remove section is denied unless I have an Internet connection which I don't have. I just do not see any reason why this is done this way! One can't even gain access with the DVD Is there a way to circumvent this nuisance from the terminal Does anyone know why this is put into the installation in the first place.?

I just upgraded to Fedora 12 on my computer. Now I can't connect to the net. Under network I show the two connections (neither working). The "connect" and "disconnect" AND the "delete" buttons are all grayed out (?). I also can't log in as root to try to gain more access. Probably just a new way of doing things. I was upgrading from F7 so it was a bit of a jump.
Does the network utility work differently from 7? Am I now rootless? It would seem that my wifi card sees the net as I can see the routers out there, but can't connect. I'm sure I'm using the correct WEP.
I can disable the internet in mswin(XP) to gain some FPS in games. How can I disable the internet and enable the internet as needed? I have suse 11.4 and kde. Through command line?

I have got openvpn running on my system with certificates and open to the IP addresses 17.xx.xx.x on the server.
What should I definitely block off from the system so that anyone using the VPN cannot gain access and how should I go about this in the firewall?
I'm guessing to block off intranet access to the webserver.
I have mysql and some mail programs running as well - how can I block those off?
I'm running 32 bit Ubuntu 10.04 with 2GB RAM. Is my processor (AMD Athlon 64 X2) running sub-optimally?Given that a larger addressing space will make no difference to me (right now) would there be a performance gain or any other advantage to switching to 64 bit Ubuntu.
View 5 Replies View RelatedI am semi new to linux and i was getting the hang of it until just recently. I'm trying to do some web design using php and mysql. In my reference material (the all in one desktop reference {for dummies}). At some point I needed to do something in /var/www but I ran into a permissions problem so I typed:
Code:
chgrp -v -r guy0203 /var/www
405 chgrp -v -R guy0203 /var/www
406 chown -v -R guy0203 /var/www
Afterwards in some subsequent step it suggested putting the files in /usr/src/mysql. Since I didn't have that folder I used mkdir and created it. Then I tried adding the files I needed to that folder and got denied on the grounds of not having permissions once again. So tried something like this:
Code:
451 chmod 777 /usr/
452 sudochmod 777 /usr/
453 sudo chmod 777 /usr/
It was a 755 originally but I couldn't copy those commands. It turns out as that I had two terminals open in different desktops. one of them was a root terminal. It was at this point that realized that I was in that root terminal and decided I was done 'learning' for the day. I decided to listen to some music (which is located in my windows partion) and ran into a problem. The prompt that pops up to normally asks me for my admin PW to mount the drive. Now just vibrates like an incorrect entry was received, says authentication error and says I am not authorized to mount that drive then I went back to terminal to fix it, and when I tried to elevate myself to SU:
I got this:
Code:
guy0203@guy0203-laptop:~$ sudo su
sudo: must be setuid root
guy0203@guy0203-laptop:~$
I don't know what to do now but I think I totally killed this OS. If so is there anyway to save things if I have to reinstall?

View 2 Replies View RelatedWe have a server were we no longer seem to be able to gain access, neither locally or remotely.When we try to connect via SSH we get a "Connection Refused". We have checked that it's not our standard firewall blocking the request, so it can either be the local firewall (which we disabled when installing) or that the process isn't running.However, when we try to login locally on the machine (as root) all we get is "Login failed". We've tried restarting the machine in single user mode to change the root password, and while we can do this succesfully, it still doesn't give us access when rebooting the machine afterwards.No other users (besides the standard users created when installing) are available on the server, so we can't say if this is a problem with the root account, or with logging on in general.

I know that you can adjust the audio --that's a given, but has ANYONE come across a way, via ffmpeg, or anything else, to calculate a BASE db/gain offset, so that an adjustment could be made programmatically? Is there any software for this, or a secret ffmpeg flag for this?
