[17:02] <Christopher-Were> Hi, I've recently updated Lubuntu 14.10 inside of a virtual machine and now when I boot up I get a kernal panic
[17:02] <holstein> kernel?
[17:02] <holstein> you get a message? or, you have something that is making you think you have a kernel panic?
[17:03] <Christopher-Were> I'll pull up a screen shot 1 sec
[17:03] <holstein> you updated lubuntu 14.04? with something like "sudo apt-get update && sudo apt-get dist-upgrade"? can you locate an older kernel and try booting it, please..
[17:03] <holstein> if youcan get in with the older kernel, run the command i gave, and share errors..
[17:04] <Christopher-Were> there's no older kernal on the grub menu
[17:04] <holstein> you only have one kernel? in the list? you have no "older entries"?
[17:04] <Christopher-Were> nope
[17:05] <holstein> you should have a recovery mode for the one kernel you have.. can you get into it?
[17:06] <Christopher-Were> at the moment it's not booting into anything. It's just a blank blck screen before it even gets to the grub menu
[17:07] <Christopher-Were> okay I'm at the grub menu and it only lists 3.18 and no other kernal
[17:08] <holstein> sure, so, where i suggest to boot the recovery kernel mode, for that kernel, try that
[17:08] <Christopher-Were> it gives me options of systemd, upstream and recovery mode, but all of those cause the same kernal panic
[17:08] <holstein> you should see "older kernels"..
[17:08] <holstein> why are you saying "kernel panic"? does something say that?
[17:08] <Christopher-Were> yes it says kernal panic
[17:09] <Christopher-Were> I'll send over  a screenshot of the error
[17:09] <holstein> Christopher-Were: can you get into the recovery mode? yes or no?
[17:09] <Christopher-Were> no
[17:10] <holstein> i think you are in the chroot in and fix something state..
[17:10] <holstein> i would start with a live iso, and see if the file system can be repaired
[17:12] <Christopher-Were> Is upgrading in ubuntu even stable? this isn't the first like upgrading has caused me problems
[17:12] <holstein> Christopher-Were: i dont know what you are referencing, friend
[17:13] <holstein> if you mean, upgrading the version from 14.04 to 14.10, sure, that *can* be stable
[17:13] <holstein> but, there can also be issues..
[17:13] <holstein> is that what you did? or did you just do a system update?
[17:13] <Christopher-Were> I mean just upgrading within the same release, which is what seems to have caused this problem
[17:14] <holstein> Christopher-Were: i dont konw what you have upgraded, or how
[17:14] <holstein> Christopher-Were: also, if you have 3rd party sources, or not..
[17:14] <Christopher-Were> i don't have any
[17:14] <Christopher-Were> thanks very much for your help, but i've got somewhere to be right now. Maybe Lubuntu isn't stable enough for y uses anyways. Thanks bye.
[17:14] <holstein> one should always have backkups, regardless.. in virtulized os's, i'll take a snapshot
[17:35] <rawhead> Hi all
[17:36] <rawhead> Could anyone help. I got Logitech usb mouse, MX500. It moves slow on lubuntu
[21:15] <Christopher-Were> Hi, does anyone know where I can change my default sound device in Lubuntu 14.10?
[21:19] <Christopher-Were> hello?
[21:23] <Christopher-Were> Hi, does anyone know where I can change my default sound device in Lubuntu 14.10?
[21:24] <Unit193> alsamixer and hit F6 to select sound device.
[21:25] <Christopher-Were> that doesn't change my default sound device.
[21:25] <Christopher-Were> What I'm looking for is the ability for the taskbar slider to corrispond with by usb sound device
[21:26] <Unit193> Might be easier for you to use pulseaudio.
[21:26] <Unit193> !pulseaudio
[21:26] <Christopher-Were> I've installed pulseaudio
[21:26] <Christopher-Were> but I'm having a little difficulty in how to selected my default output device
[21:35] <Christopher-Were> The issue is that I'd like the volume control on the taskbar to work with my usb card
[21:35] <Kamilion> Christopher-Were: that's supposed to be what pulseaudio is for; finding ALSA based audio devices and managing them. In your case, it should be trying to select your USB device in preference to any onboard audio chips.
[21:36] <Kamilion> uhh, it's been a while, but I know there's a number of gui and cli tools for poking at pulseaudio's state.
[21:37] <Kamilion> if I remember correctly, the package is pavucontrol to get the graphical pulseaudio tool
[21:37] <Christopher-Were> I've got pavucontrol up but it can change what the taskbar mixer corrisponds too
[21:37] <Christopher-Were> I've also got the xfce4-mixer but that's no help either
[21:37] <Kamilion> most of those will be controlling alsa's mixer
[21:37] <Kamilion> IIRC
[21:37] <wxl> Christopher-Were: alsamixer
[21:37] <Unit193> Kamilion: That it is, but I believe the lxpanel plugin works with alsa.
[21:38] <Kamilion> that'll set the hardware volume controls, yes
[21:38] <Kamilion> but it won't let him choose the output device, from memory.
[21:38] <wxl> sure it will
[21:38] <Kamilion> normally pulse takes care of it automatically -- when I plug my plantronics headset in, it correctly moves the audio over to it without me doing anything.
[21:38] <Christopher-Were> okay, because my usb headphones have a volume control on them which works with the volume slider in the taskbar, do I need to use a different applet?
[21:39] <Kamilion> Oh, wait... Uh, how much did you pay for that USB audio device?
[21:39] <Christopher-Were> why do u ask?
[21:39]  * Kamilion has a little  one here from china that says it's 7.1 channel cmedia chipset, but the volume control is either ALL THE WAY UP or whispers and nothing in between
[21:39] <Kamilion> /me has a little $4 one here from china that says it's 7.1 channel cmedia chipset, but the volume control is either ALL THE WAY UP or whispers and nothing in between
[21:39] <Kamilion> even on windows.
[21:40] <Christopher-Were> Oh my headset was about £30. The volume controls work fine in KDE
[21:40] <Kamilion> I ended up using the volume dial on my speakers for that :/
[21:40] <Kamilion> okay, so the mixer does work.
[21:40] <Kamilion> so we've ruled out hardware fault if KDE demonstrates proper behavior
[21:41] <Christopher-Were> the usb mixers works, the volume slider in the taskbar picks it up, but when I change the volume via the controls it changes the volume of the onboard soundcard which I don't want
[21:41] <Kamilion> ohh.
[21:41] <Kamilion> So you're trying to get the tray control to target a different device
[21:41] <Kamilion> gotcha
[21:41] <Christopher-Were> presumably because the tasbar slide changes the volume of the default sound device
[21:41] <Christopher-Were> exactly Kamilion
[21:41] <Kamilion> http://puu.sh/hl2HH/b4e0c59d13.png  <--- you can see mine here, on this system.
[21:42] <Kamilion> but that's being fed to the VMs through vmware workstation
[21:42] <Christopher-Were> i see
[21:42] <Kamilion> gimme a couple minutes to poke vmware and set the device up for USB passthrough to a VM
[21:43] <Kamilion> and I'll see if I can replicate your issue.
[21:43] <Christopher-Were> maybe there's another taskbar volume applet I can use? if the lxde one only uses alsa
[21:43] <Kamilion> I think there's a couple others
[21:43] <Christopher-Were> I know KMix works, but obviously that would be kinda clunky with LXDE
[21:43] <Kamilion> check the software store for 'mixer' or search through the package lists with synaptic
[21:43] <Kamilion> oh, don't worry about that
[21:43] <Kamilion> I have kvirc installed on my lubuntu box
[21:44] <Kamilion> it brought in half of KDE, but I don't care
[21:44] <ianorlin> depends how much resources you have though
[21:44] <Kamilion> i just want my pretty, themed IRC client.
[21:44] <Kamilion> yeah. The libs on disk are pretty small, only a few hundred megs...
[21:44] <Christopher-Were> I have 16gigs of ram so resources aren't an issue, but I'd like it to be as snappy as possibly
[21:45] <Kamilion> as long as you're running lubuntu, there ain't much else running in the background to slow things down.
[21:45] <Kamilion> :D
[21:45] <Kamilion> The only bone I can throw you is, try some other mixers from the repository and see what works
[21:45] <Kamilion> a good trick for that is grabbing a livecd, stuffing it on a USB stick
[21:46] <Christopher-Were> the xfce4 one seems like it might do the job
[21:46] <Kamilion> and installing packages on that to find one that works best before committing to installing it on your main disk
[21:47] <Christopher-Were> im sorry, what do you mean by that?
[21:51] <Kamilion> whoops, sorry.
[21:51] <Kamilion> hadda step away from the KB for a moment, guess it was a moment too long.
[22:00] <Christopher-Were> hmm no success as of yet
[22:09] <Christopher-Were> Okay, I'm not finding any suitable ways to deal with this.
[22:11] <Christopher-Were> I don't understand why this is so difficult on Lubuntu or why other people for some reason haven't had to deal with this
[22:13] <Christopher-Were> Is there a way I can have an icon in the taskbar open pauvcontrol? Since it doesn't appear the LXDE's menus there doesn't seem to be an option to add it to the taskbar as an application launcher
[22:15] <Christopher-Were> Is anyone still here?
[22:17] <ianorlin> yes with volume prefrences on the applet
[22:17] <ianorlin> or volume control settings once pavucontrol is installed
[22:18] <Christopher-Were> i think i need to explain the problem again, you're not the person who was just helping me
[22:19] <ianorlin> I was reading the scrollback
[22:20] <Christopher-Were> I have a usb interface which is not my on-board soundcard. I'd like the volume mixer in the taskbar to corrispond with my usb device not the onboard card. Now apparently this is impossible because LXDE works with alsa not pulse audio, which means I need a new audio mixer. I've tried the xfce4 one but it doesn't seem to want to work.
[22:21] <Christopher-Were> Is there a simple audio mixer which fits into the system tray where I can select my device. Or can I just click a launcher to launch pavucontrol since I know that works. It's a clunky solution, but at this point I'll take it.
[22:22] <Christopher-Were> basically a gtk version of kmix
[22:27] <Christopher-Were> Dang it, now I've lost all sound
[22:27] <Christopher-Were> I dn't understand why this is so difficult
[22:30] <Christopher-Were> So if I wanted to launch pavucontrol from the taskbar. How would I go about it?
[22:31] <ianorlin> right click on the quick launch area and click application launch bar settings
[22:32] <Christopher-Were> okay, I'm there now
[22:32] <Christopher-Were> It seems to be allowing me to add menu items, not custom commands
[22:33] <ianorlin> ah you would need a to create a .desktop file for that
[22:33] <Christopher-Were> seriously?
[22:37] <Christopher-Were> I think my PC setup might be a bit too much for Lubuntu. Do you know if it's possible to do a "sudo apt-get install ubuntu-mate-desktop" and remove lubuntu by "sudo apt-get purge lubuntu-desktop"?
[22:37] <Christopher-Were> or am I just playing with fire with that?
[22:37] <ianorlin> lubuntu-desktop is just a metapacakge
[22:37] <ianorlin> Christopher-Were: I don't actually have a usb audio device though
[22:37] <Christopher-Were> yes but apt-get autoremove should work everything else out right?
