Kernel 3.17 no longer allows bonding ppp devices
by Toby Corkindale 18 Nov '15

18 Nov '15

Hi, I hit a problem when attempting to upgrade to kernel 3.17.2 on a particular server. Some time between 3.13 and 3.17, the bonding driver has stopped accepting ppp devices, instead throwing an error that the MAC address cannot be changed. (And does not allow this to be forced) I suspect it's unlikely.. but has anyone here encountered this issue and found a solution? Alternatively.. do you know where the right place to file bug report about this would be? It's been a while since I've filed anything against the linux kernel itself. Cheers, Toby

X login problem
by Craig Sanders 30 May '15

30 May '15

can anyone think of any reason why on one of my systems I can't login with lightdm? as soon as I do (with any account, including a brand new one without any weird/old/obsolete dotfiles), it seems to login OK but then logs out again immediately. my normal desktop environment is xfce, but the same thing happens if i tell lightdm to use lxde or gnome or anything else. logging in on a text VT and running startx works perfectly, and is how i've had to login for the last few months. I have four other very similar systems where lightdm works without a problem, including a mythtv box set to auto-login as the mythtv user. two of them are sysvinit, two of them are systemd. i can't see anything in the logs to indicate any problem, even the auth.log just shows that the session was started and then the session terminated immediately afterwards. any hints on what to look for in the logs or where/how to increase debug log levels would also be appreciated. craig -- craig sanders <cas(a)taz.net.au>

The particular app I am thinking about can be confgured to display the latitude and longitude from the geotags, unfortunately I have forgoten its name. Anyone know of it please. What I am requireing is an image viewer that will display the geotag data in some format. Lindsay

S5 Slide show works OK under Mozilla but not on Explorer
by zlinw＠mcmedia.com.au 01 May '15

01 May '15

Hi all, I am putting together a slide show of a large engineering project. S5 is the framework being used "http://meyerweb.com/eric/tools/s5/". The slide works great under Firefox, but its quite unexecptable under Microsofts Explorer. As the majority of the target audence would almost certainly be running windows, I appear to have a problem. THe way the slide show works is one changes frames with the page up/down keys. The frame is divided into three sections. The top section containing the comments to go with the image, the middle portion is the image, the lower section containing the overall title. Explorer takes no notice of this formating, not even using the selected fonts just displays a series of images with text in between them using whatever default font Exlploer has. Unfortunately although now running Linux for around 20 years I no nothing about web programming, or in this case xhtml and css what ever they are? :-(. Anything I can do? Help would very much be apreciated. Lindsay

Thanks for the reply, I am familiar with qeeqie, its a good app for images but it does not display the GPS IFD from the exif data. Note 1. I have found an answer though, slightly unfortunately it does not appear to be in Debian, its the Java app "geotag". Availible from......... http://sourceforge.net/projects/geotag/ It uses googleearth via the Chromium browser to display the geo tag position, works great. For install info see........ http://geotag.sourceforge.net/QuickStart/ One of course needs both chromium and googleearth installed. Lindsay Note 1: I use a Nikon D700 with the GPS1 attachment that automaticly tags the image with its current GPS data when you take a shot. A REAL great asset I may say.

Pro tip: Exclude /var/lib/docker from mlocate db
by Toby Corkindale 29 Apr '15

29 Apr '15

If you use docker much at all, I highly recommend excluding it from mlocate, if you use it. At least, with the btrfs version of docker (the only one worth using), you end up with what looks, to the filesystem, like an immense tree hanging off /var/lib/docker. And naive mlocate iterates through the entire lot, indexing it.

Running apps not appearing on "MATE Panel 1.8.0"
by Carl Turney 28 Apr '15

28 Apr '15

Hi, Am running Linus Mint Qiana with the Mate interface. It's set to some classic mode, if I recall correctly (to look as similar as possible to an old Gnome style). Normally, the "bottom panel"(?), along the bottom of the screen, displays these things... -- Towards the left: "Menu" (which leads to Shutdown, Search, and all the installed apps), and all created short-cut icons. -- Towards the right: Date, time, network connection icon, System Update icon, sound control icon. -- In the middle: Tab for each application that is currently open and running (Firefox, Thunderbird, LibreOffice, etc.) But, in just the last day, all of the currently running apps (i.e. normally tabbed in the centre portion of the panel) do not appear in the centre of the panel. I'm only accidentally and haphazardly getting various programs to reappear on the screen, after I have minimised them, but I'm not sure how. Cause: Maybe I controlled my mouse incorrectly and can't recall how, and have configured the panel incorrectly? I've read through the Help offered when right-clicking on the Panel, and can see an incredible range of features, but nothing on making the tabs dis/appear for all running programs. Can anyone please help? ASAP? I'm concerned about shutting down the system with running apps and have trouble getting the running apps I want to access to "reappear" on the desktop. I have rebooted the system, but that hasn't fixed it. i.e. Minimised apps don't appear in the Panel. I think it only has one "desktop". i.e. There doesn't appear to be a shortcut way to switch between 2-3-4 different desktops/workspaces. So I don't think that's the problem. Thanks VERY much for any pointers. Carl Bayswater

Raid and Linux
by Daniel Jitnah 28 Apr '15

28 Apr '15

Hi all, I have a system running on a Linux *software raid* 10 setup on Ubuntu 14.04. This system is running very well. However for some reasons this system needs to be moved from one (hardware) host to another host (a HP ML110 G7 Proliant Server). I had in mind to just take the drives from one machine to another. (The actual workload is in a VM hosted on a very basic KVM installation. so as long as I get a base host running, I am happy!) The HP Proliant though has hardware raid, (and I don't think I can disable it. The original host does not have raid.) Q: Can I install software raid on top of a hardware raid system? if Yes, how would I set the hardware raid? in effect I need the software raid to still see 4 hard drives? Thanks Daniel.

In-place online encryption
by Noah O'Donoghue 27 Apr '15

27 Apr '15

Hey all, I have a few cases where I'd like to encrypt without taking the system down for extended periods, ie, servers. In the windows/apple world truecrypt / bitlocker / filevault will all let you encrypt the root partition as a background process, throttled to a low IO load. Usually this requires a reboot to get started, then runs in the background. Does anyone know how to achieve this in the Linux world? (preferably with luks) -Noah
