Tired of three-stage shutdown in Tellytubbies Eee, I opened a terminal and tried: shutdown -h now Ripost was: Bash: shutdown: command not found (Original command taken from The One Page Linux Manual) To save me lots of GPRS-wasted time, does anyone know what the magic words are, pretty please? -- Tony Anson www.girolle.co.uk/

Thunderbird colours in Ubuntu 10.04
by Mark Rogers 24 May '10

24 May '10

I've just upgraded to U10.04 using the default (I think) Radiance theme. I'm slowly getting used to the new min/max/close icon positions. However, in ThunderBird, the folder listing used to show folders in three different styles: bold black for folders with unread email in them, bold blue for folders with *new* unread email in them, and black (not bold) otherwise. Now, in U10.04, the folders with new unread email are still bold but now in a light grey colour, making them far less prominent than the other two folder states despite being the most important. (a) Is this just me? It could be something I've tweaked in the past and need to un-tweak (b) Any idea how to change this? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Virtual Box Query
by Mark Jonathan Myatt 23 May '10

23 May '10

Hello all - I have been running Fedora Core 12 for the last few months having previously been using Core 11. I am now wishing to have the use of a virtual box to run an existing MS Family Tree package on Windows 2000 professional. I have been unable to find a comparable Linux product. Whilst I have been using Linux for a number of years now I remain uncomfortable using Bash although I have some successes. So for the purposes of this enquiry please treat me as a 'terminal' user. I have been unable to complete the loading of the virtual product provided by Oracle: "Oracle VM Virtual Box 3.2.0.r61806". Although the software has been loaded correctly as well as Windows 2000 when trying to start it the following error message appears: "Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary." I confirm DKMS and GCC have already been installed. When I do as instructed above the following error message appears: "[Mark@Mark ~]$ su Password: [root@Mark Mark]# /etc/init.d/vboxdrv setup Stopping VirtualBox kernel module [ OK ] Recompiling VirtualBox kernel module [FAILED] (Look at /var/log/vbox-install.log to find out what went wrong) [root@Mark Mark]# " When I look at /var/log/vbox-install.log I get the following response: "[root@Mark Mark]# /var/log/vbox-install.log bash: /var/log/vbox-install.log: Permission denied [root@Mark Mark]# " The when I look at Var/log etc to see what can be done the following message appears: "Attempting to install using DKMS removing old DKMS module vboxdrv version 3.2.0 ------------------------------ Deleting module version: 3.2.0 completely from the DKMS tree. ------------------------------ Done. Creating symlink /var/lib/dkms/vboxdrv/3.2.0/source -> /usr/src/vboxdrv-3.2.0 DKMS: add Completed. Error!

You can use the --kernelsourcedir option to tell DKMS where it's located. Failed to install using DKMS, attempting to install without Makefile:159: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop." It is at this point I am now lost ! I don't fully understand the question. Any help on this will be gratefully received. One other query while I am writing; as follows: I have been trying to regularise the setup of my two HP printers. When using bash using the command hp-setup I get the following error messages:- "HP Linux Imaging and Printing System (ver. 3.10.2) Printer/Fax Setup Utility ver. 9.0 Copyright (c) 2001-9 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to distribute it under certain conditions. See COPYING file for more details. QGtkStyle was unable to detect the current GTK+ theme.

Help towards sorting this out will be much appreciated Mark Myatt (Saxmundham)

Random Lock-ups of my Ubuntu Box?
by James Bensley 23 May '10

23 May '10

Hey List, I have an Ubuntu 9.10 box on which I recently created a software RAID6; you can see what it looks like in rather good detail if I may say so my self ;) here: http://i48.tinypic.com/30jrbdl.jpg After this set up was all done I shut the machine down for the night. Now when I boot the machine up to start using the array it wants to run the file system check utility, fsck I believe (like it normally does, every N days or N mounts, "which ever comes first"). This is fine, I assume it wants to do this because its a new volume and I like to know everything is working fine so I would always let this run on any of my machines but on this machine, it gets to the desk top, I can see the process is running via top or the process monitor, but within 1 minute of being on the desk top the machine will locks up and is unrecoverable so I am forced to turn it off? This happens every time, so ever since a week ago when I first made this RAID array, I haven't actually used the damn thing yet! I can't understand why this would be; I thought it may have been the power supply as it is only 250 watts but I have the machine connected to a watt meter and I added the drives one at a time watching the watts increase, we are only at 140 Watts? I had thought that maybe it was to many devices on one single power cable coming out of the power supply as I have had to use splitters on the power cables so I swapped the power supply out temporarily for one in another machine that is rated for 500 watts and had more power cables coming out of it but no...I also stood another machine next to it, turn them on at the same time and used the 2nd machines power connectors to power some of the drives so the power was shared between the two PSUs, but no it still locked up Next I thought it was the south bridge being over run but surely it wouldn't of been able to sit there for 20 hours building the RAID and formatting it? Is it possible that the building of the RAID wasn't very intense and now its all set up, when it tries to boot to the desktop and run fsck this is now making the drives work hard and so that only now the systems weakness is showing? (I did try increasing the south bridge voltage but the options in the CMOS are very limited and so I think there was a difference, it stayed on the desktop for 2 minutes before locking up instead of 1, but I can't remember, this would need validating). I would love to hear anyone's thoughts on how I can get this working again? P.s. sorry for the length! -- Regards, James. http://www.jamesbensley.co.cc/ - There are only 10 kinds of people in the world, those who understand trinary, those who don't understand trinary and those who don't understand trinary.

time for an upgrade
by nev young 22 May '10

22 May '10

Hi, So I've been running kubuntu 8.04 (i386) for a couple of years now on my main PC and I'm seriously thinking of loading up ubuntu 10.04. Mainly because both laptops run ubuntu (one 10.04 and one 9.10) and the differences between gnome and kde keep catching us (me & the missus) out. I'm thinking of using the 64 bit version of 10.04 to get more out of the machine[1] but can not decide whether to load ubuntu server and load the destop bits or load ubuntu desktop and load the web and file server bits. Any advice or suggestions over and above my current plan of split the root partition[2] into 3 and have a triple boot to try each in turn. -- Nev [1] AMD AthlonX2 64bit dual core @ 2.2GHz [2] 135GB free, 9% used.

Looking in my wallet, there's a big hole there with about fifteen quid unspoken for, cowering in the corner. This has to last me until Monday. OK, if in Norwich I could raid the hole in the wall, but it is getting a little late in the day for tidying everything away into the workshop, cleaning-up and finding a presentable change of clobber.

Mystery!
by Ted.Harding＠manchester.ac.uk 20 May '10

20 May '10

Sorry to be completely off-topic, but there's quite a few of you who are savvy in rare areas; plus, you're local! Scenario: At times during the last few days I've seen a low-slung white car/van driving around. It has "Anglian WILLHIRE" on the sides. On the roof is mounted a blackish flat plate, about 15in x 9in in size and angled so that it is elevated about 45deg above the horizontal and facing forward. Perpendicular to this plate (therefore pointing upwards at about 45deg to the vertical) is an array of rods, which seem to be about 3in long and about 1/2in (or a bit smaller) in diameter. I couldn't count exactly, but I'd say it looks like a 4x6 array. (All quantities in this description are approximate!) I first saw this vehicle driving over the farmer's field opposite my house last week, some yards in from the edge and driving parallel to the edge. It was actually driving on the earth of the field, not on any track. I've subsequently seen it 3 times, driving along the road (a) between my house and the fields, (b) coming back over the bridge to the NorthEast over the Little Ouse river. See at postcode CB7 4TG on google maps for topographical reference (The "A" pointer you will get is close to the point from which I first observed it). Clearly this is monitoring something, but I cannot imagine what. What would the little rods on the plate be for? Any ideas? With thanks, and apologies once again for going OT!

MP3 Plays Only In Command Line
by Simon Royal 18 May '10

18 May '10

Hi I am still battling with sound on my ThinkPad 600 running Xubuntu. I have managed to get some sound and even play MP3 via command line - mpg123 and mplayer. But I cannot get any program to play it. It either doesnt play at all or plays so crackly you cant even hear the music. Is this a hardware limitation or am I doing something wrong? Please help, I am a fairly new Linux user. When using mplayer via command line I noticed that it said 'pulse' is this the audio output engine/settings it is using as under Mixer there is also a mention of Pulse under one of the Output options - along sine OSS and Alsa. Your help would be greatly appreciated.
