I have freshly installed an Ubuntu 10.04.1 by internet.
All is running well, but my nice values are all set to 0. Is there a script that handles these at boot time? How can I reset them to "appropriate" or "normal" levels (e.g. not all at 0)? I know in other installs, my nice levels vary depending on the process and the user.
Attached is a screen shot of my gnome-system-monitor, and aside from init, which I had set to -15, all others are at 0.

I am an experienced redHat/Fedora sysadmin but I'm completely new to ubuntu/debian world and the-way-the-things-works. I am trying to understand a few things. One of them is security related. Is AppArmor an extra security layer that protects individual services based in what is the normal and expected behavior, right? Why it is disabled in all run levels expect level 6 (reboot?)? Should I enable it on all run-levels? Should I select which service to protect or the defaults are fine ?
Is netfilter, the basic packet filter on Ubuntu 9.10? I founded iptables and I installed firestarter, but looks like firestarter is protecting nothing from outside, based on this iptables -L output: Code: Chain INPUT (policy DROP) target port opt source destination ACCEPT all anywhere anywhere
This is right? The default policy is DROP but there is a rule that allows anything from anywhere? This make any sense ? And finally, what is ufw and why it is disabled in all runlevels? Is ufw a replacement for iptables, or firestarter or it is a completely new animal? Should I use ufw instead firestarter? I am impressed about how different is Ubuntu/debian from other RH based distros. I just realize how much I have to learn about this new stuff.
For some reason, it cannot change my zoom levels like before in numerical order with the zoomy extension.I have tried refreshing the page and restarting the computer, this is with Jaunty.
I have a epson sx100 and i can't check my ink levels with esputil. This is what i get when i type the command.
pianoterra@pianoterra-desktop:~$ sudo escputil -r /dev/usblp0 -s Escputil version 5.2.0-rc1, Copyright (C) 2000-2006 Robert Krawitz Escputil comes with ABSOLUTELY NO WARRANTY; for details type 'escputil -l'
[Code].....
I also have another problem which is i can't change the permissions of /dev/usblp0 because i stupidly changed them in to read write execute to all using chmod 777 without thinking that the device file isn't executable. Why can't i change the permissions back as they were?
I was wondering if there is any kind of tool that i could use to check the ink levels in the printer. It is blinking that one of the carts is out but there is 4 in this printer. Its a pain in the **** having to hook it up and install it to a windows computer just so i can see what cart i need to replace. I went to System>Administration>Printing> Right clicked on the printer then went to Properties>Ink/toner levels> In the box it says "Marker levels are not reported for this printer" Hmm so basically i shouldn't use this printer?
I am using UNR 9.04 with Alsa 1.0.22.1 For some reason everytime I reboot my volume levels reset to headphone & speaker muted and headphone/speaker/PCM levels all set to 0%.
Does anyone know if there something I can that will allow my levels to be the same after I reboot? or if there is a script out there that will set my levels on startup?
If there isn't a script what would I do to create my own? also what would I do to have it auto run at startup?
The problem is some of the songs are louder than others, in other words set the volume and next thing a song comes along that scrambles your brains it's so loud, Or you get one you can't hardly hear.
I've used a couple of GUI's in the past, but all of them seem to do one song at a time. Not really an option with over 10,000 songs.
What would be nice is if I could pick one song as a base line and using terminal run a batch of say 500 songs through it.

Use Rhythm box to handle music currently.
Been using since Dapper Drake, I'm not afraid of the command line, but I am far from an expert user, in other words I know just enough to be a danger to myself and others
I've never written a script file to automate anything but this may well be a time to learn one.
I've been using Ubuntu 10.10 for almost a year now and I'm really happy with it. I completely uninstall windows from my computer I'm able to do everything a used to do on Windows now on Linux, and even more... except for one thing... I cannot see the ink levels of my printer. It's a multifunction Epson Stylus TX110. I installed escputil and used the command "sudo escputil -i -u -r /dev/usblp0", the printer then starts making noise and no matter how long I wait, it never presents any info or displays the message: "device is busy" with no info about the ink levels.
I followed the tutorial on URL... on Ubuntu but I don't get all my mail in one nice big file instead, I get possibly every message, each one given a horrible filename URL..What could have gone wrong while following the tutorial?
i have this weird problem with my pavucontrol. for some reason my input levels go up and down by themselves when i'm talking on skype...mostly up...and it's annoying because i'll be talking normally, but to the people i talk to on skype it sounds like i'm yelling, and i have to have pavucontrol open always to constantly keep the levels under control..i've made a short desktop recording showing what i mean.i didn't include sound, but as you can see, i'm not turning the levels up manually..i just talk and they go up by themselves
I just recently installed ubuntu so I'm quite lost on some stuff. This little annoyance comes from the volume levels in Ubuntu 10.04. I have partitioned my computer to have dual boot into windows and ubuntu, so I know the problems are not related to the hardware itself as everything works just fine in windows. I am using a Dell Inspiron 9400, for reference.
The multimedia keys on the computer respond correctly but on the lower three volume settings sound completely drops out as if I had muted the computer. I went into the Alsa mixer to see if I could configure these sound levels and sure enough the master volume was down to zero, PCM and LFE are also low . I changed the settings of the lower levels but when I press on the volume up or down media keys to switch level the settings get reset. I tried just changing one level, exiting and saving through alsactl but it didn't stick. Even after reboot the settings are back to the zero volume on the first levels.
I'm new to Fedora and must say I love it. Previous Debian and Arch user but feel at home now. I'm after a difinitive answer for this issue as I can't seem to find what I need anywhere. I'm running Fedora 11 kde 4.2.4 with an Epson Photo Stylus RX425 printer / scanner combo connected via usb. Is there any way to moniter the ink levels in this printer? I'm tearing my hair out.
I am running F12 and I use Amarok to manage/play my music library.
I keep having a problem where the mixer 'Surround' in my alsa volume gets maxed whenever I switch tracks in Amarok. I want to stop this from happening because it causes my speakers to buzz just loudly enough to drive me crazy.
I don't really now where this goes but figured i start in the general forum, mods please move as needed.I got my f12 install up and running great. I recently burned an audio cd. when i used it in my car i noticed i had to turn the volume up a lot more then on my other burned cds. previously i used my mac to burn cds. the mp3 files are the same, they are located on a external hd that both computers access. the difference is significant. any ideas on why this is?
I noticed that thare are different default priviliges for the user depending if I boot in run level 3 or 5. Normally I use init 5 and login in graphical mode straight to Gnome desktop. Then all my USB devices (memory and external USB sound card) are accessible and work. If I log in throught termina (init 3) then USB has to be mounted and the sound card is not recognized.
Is there any general rule for such behaviour? If I plan to use level 3 shall reconfigure the system go get immidiate acces to usb sound card?
I'm currently running on a really old computer with one proc and little memory. It's just enough to get skype running but it only works well enough if I change the nice level to -5 or lower. Now the person that uses skype in the house is really the wife, I don't want to teach her how to open htop in command line, fine the pid and then use the correct command to change the nice.What I am looking for is a script (sorry I don't know thing one about programming/scripting) that will change the nice priority periodically for all pid that are skype. This way call processes will get reniced as well. I know better then to run it as root/sudo, but I am at a loss (even searches came up with not much) on how to do this.
Trying to grab the Empathy window class doesn't produce any results and adding "empathy" as a windows class to control only affects the "about empathy" window and not the conversations or the contact list.
It'd be nice if Empathy behaved like the rest of my programs and allowed me to restrict it to a specific workspace. Not sure what class I should be using.
my idea is to have gvim working like gedit in ubuntu 11.04: when you open a file thru unity's dash, and if there's already an open editor, it opens the file in a new tab.To make nautilus open more than one selected files in gvim's tabs, i used to change the exec line in /usr/share/applications/gvim.desktop to "Exec=gvim -p --remote-tab-silent %F". This trick is working ok in nautilus and also in unity, just like the way I was planning.
However, when i try to open gvim itself without specifying any files (from unity's dash or a launcher set) it fails. Can anyone please help me with this ?
I am currently troubled with a very annoying problem - the volume level of the PC is jumping higher and lower at random intervals. It makes listening to music very difficult, as at times the music can go from just right to overly loud, just to fall right down so that it is hard to hear. I've only noticed this problem in the past few weeks, and I can definitely say it wasn't an issue in 9.10. This is a fresh install btw, not an upgrade.
Some details: Using motherboard sound, Realtek HD Audio, iirc. Below is the output of lshw, with the irrelevant parts cut out.code...
I am asked to look for a very nice sms gateway with a good GUI be it commercial or free. where can I find a nice smsgateway with GUI? I looked at kannel but it didn't mention any thing like GUI so am not sure I will go for it.
hHow would I add my SSH server to run levels 3,4,5? I have been trying to search google for this answer to my problem for hours and cannot have any luck.
I have CentoS 5.3 and switching init levels does not work.when I login console mode,doesnot work ctrl+F7 key...and on the contrary.when Im in graphical mode, does not work ctrl+F1...ctrl+F6 keys.
I've been searching for the answer to my question for quite some time on google, no luck. Due to my searchings I've become very familiar with nice and renice.
I have a script I use for launching a game installed with wine. I cannot/wont run this game as root but I need to be able to use nice --7. As of now I can't I -- ofc -- get "permission denied"..
So how do I make the full range of niceness ( [-19;20] IIRC ) available for all users on my system -- or even just for 1 user?
