Unbootable 2.6.28 kernel
by Dan Hatton 20 Jan '09

20 Jan '09

Dear All, When I try to boot into kernel 2.6.28, I get a kernel panic with message `VFS: Cannot open root device "hda1" or unknown block (0,0)', followed by a list of available partitions which suggests that, between kernels 2.6.27.10 and 2.6.28, the drive on which I keep my root filesystem has changed its name from /dev/hda to /dev/sda. Is this expectable behavior? Should I edit my "root" boot option and fstab accordingly? Or does it indicate something wrong? -- Thanks, Dan

Apart from the SAK Magic SysRq sequence does anyone know of a way to kill all the processes that have a particular virtual console open? TiA, Steve.

Magic SysRq and odd scan codes
by Steve Fosdick 20 Jan '09

20 Jan '09

Related to my other message I found that, with my current keyboard, Magic SysRq is not working. It is definitely compiled into the kernel. Documentation/sysrq.txt in the kernel tree suggested that the SysRq sending a strange scan code may be the reason. Running showkey -s gives me the following codes for SysRq: 0xe0 0x2a 0xe0 0x37 - on key down 0xe0 0xaa 0xe0 0xb7 - on key up. This does not match the description in setkeycodes which says that keys generate one or two byte sequences whereas this is clearly a four byte sequence. Has anyone seen anything similar or have any ideas if the necessary mapping can be established? Regards, Steve.

HTML table editor - any recommendations?
by Chris G 17 Jan '09

17 Jan '09

I'm looking for a simple way to create HTML tables. In particular I want to be able to create tables with various (and fairly random) row spans and column spans. I don't really mind how it works, it can be a Web based application, a word-processor look-alike, or something that converts a text 'source' file into tables. I just want it to be simple to use. Currently I'm using reStructuredText which does most of what I want but its "Grid Table" syntax for tables is laborious to use and its "Simple Tables" don't give me all the row and column spans I need. I might take a look at Open Office, I assume that can generate HTML, what's its tables like? -- Chris Green

Wireless keyboard with trackball for Linux - any experience?
by Chris G 17 Jan '09

17 Jan '09

Does anyone here have any experience of using a wireless keyboard with trackball built in with Linux? E.g. something like:- http://www.kenable.co.uk/product_info.php?referer=froogle&products_id=1789 I guess it will probably "just work" but I'd like to be sure there aren't any odd issues before I buy one. It's for a multimedia (well more of a photo display) box to go with the big new TV. -- Chris Green

Wierd DHCP problem - help!
by Chris G 16 Jan '09

16 Jan '09

I have just built (well, re-installed the OS on) a new system and have connected it to my LAN. It's running xubuntu 8.10 and uses the TV as its display device (probably irrelevant). It all installed fairly smoothly and appeared to work OK except that the networking was a bit 'jerky'. I then found that I couldn't ssh from the new machine to my desktop machine whereas other machines on the LAN could connect OK. It turned out that this was because the machine had the *same* IP address as my desktop machine. This of course explains the 'jerky' networking too! However I really can't understand *why* it has decided its IP address is 192.168.1.4. OK, some details, the router IP is 192.168.1.1 and it's the router that provides DHCP to the network. Most machines have static addresses, in particular my desktop machine (as noted above) is 192.168.1.4. The router is set up to start handing out DHCP addresses starting at 192.168.1.64 and this does work as there is a device (a VOIP server) which gets the address 192.168.1.64. The 'new' xubuntu system has default network setup, I have given it the name 'lounge' (which is different from all others) and it acquires its IP address and networking setup automatically on startup. So *how* is it getting 192.168.1.4 as its IP address? OK, I can fix the problem fairly easily by giving it a fixed IP but I'd love to know what's gone wrong. -- Chris Green

Prescott - how many CPUs???
by Ian Thompson-Bell 16 Jan '09

16 Jan '09

My Nephew, who is a bit of a computer whiz, recently gave me an 'old' 2.6GHz Prescott CPU to replace the Celeron in my desktop PC. This I have done and it is certainly faster. However, I use gkrellm to monitor resource usage and whereas with the Celeron just a single window occurred for the CPU usage, now with the Prescott gkrellm shows two windows labelled CPU0 and CPU1 respectively. Googling Prescott I can find no mention of more than one core but it does have hyperthreading. So my question is, how many (effective) CPUs do I have and is gkrellm accurately reflecting them?? Cheers ian

Printing problem - not printing
by Chris G 09 Jan '09

09 Jan '09

I'm trying to print some images from Digikam and having no luck at all. I have two printers both of which have been working quite happily over the past few months, one is an HP7310, the other is an HP1320. The HP7310 is connected by ethernet, the HP1320 is connected via my router (USB printer -> router). When I print from Digikam everything appears to work perfectly but nothing actually comes out of the printers. Digikam finishes, the print jobs appear in CUPS and that's where they stay for ever as far as I can see. They stay in state 'processing' for a while and then end up 'pending'. Any ideas how to get something actually printed? -- Chris Green

Motherboard with unrealistic amount of RAM supported
by Srdjan Todorovic 09 Jan '09

09 Jan '09

Hi, My motherboard, Gigabyte GA-M57SLI-S4, supports 16GB DDR2 RAM. It has only 4 RAM slots. Crucial website says: "Each memory slot can hold DDR2 PC2-6400,DDR2 PC2-5300,DDR2 PC2-8500 with a maximum of 2GB per slot." So that's 8GB maximum... Why does the motherboard then support 16GB maximum? Or is it that currently (with the current BIOS), the firmware (BIOS) or northbridge(which is the CPU) can only support 8GB for the moment, but once 4GB RAM modules are more common, they can be used one a firmware upgrade is completed? Or maybe one has to use coreboot/LinuxBIOS to be able to use that much RAM (if it has to do some 'special' SPD stuff)? Anyone have any insight in to this? Srdjan

having a fie out...
by mbm 29 Dec '08

29 Dec '08

All My wife has chuntered at me to clear out some of what she likes to call "junk" from my study - so I have gathered together sundry bits and pieces which may (or may not) be of use to someone else. The list is below. I can't be bothered with umpteen ebay bids and I'd really like it all to go as one job lot. I'm offering the lot here first because I guess some of you may actually have a use it. Sixty quid for the lot seems reasonable to me. If someone takes it all and then decides to offload some bits elsewhere, that's fine by me. But I really don't want to get into bids for individual bits. The idea is to get shot of it all. Cheers - and a happy new year to all Mick ------------------- <list> 1. Compaq Armada 4160T laptop (80Mb RAM, 6 Gig hard disk) - this dates from around 96 or 97 but still works. I have used it as an IPCOP firewall (and it comes with two PCMCIA ethernet cards if anyone wants to do this again). It currently has a clean new install of Debian Lenny. Oh, and a "laptop bag" to go with it. 2. Two of 2Gig 2.5" laptop hard drives. 3. 5.1 PCI sound card 4. AGP Video card - I think it is a 128Mb Radeon Sapphire. 5. BT Voyager 200 ADSL router 6. Maxtor 60 Gig 3.5" ATA hard disk 7. Dell latitude external floppy drive 8. Freecom Classic 80 Gig external USB disk 9. Two port Newlink PS2 KVM switch 10. Two port Sitecom USB KVM switch 11. Four port Aten PS2 KVM switch 12. Zoom X5V VOIP ADSL router (this is actually quite a good router - particularly if you want to use VOIP) 13. Two (yes, 2) BT Home Hubs - both reflashed to run Thomson 7G images - because BT pissed me off and I didn't like what they had done to the routers. I have the original images though if you want to flash them back to the crippled version. 14. Belkin PCI wireless card - 802.11g 15. One Microsoft USB fingerprint reader (it was freebie from MS - honest!) ------------- </list> --------------------------------------------------------------------- The text file for RFC 854 contains exactly 854 lines. Do you think there is any cosmic significance in this?

A good brand of USB stick?
by Ted.Harding＠manchester.ac.uk 29 Dec '08

Hi Folks, Sorry for possibly irritating cross-posting! Fairly recently, on one of the Linux lists I read, someone (or more than one) made suggestions about good brands of USB sticks, with particular reference to lifetime under repeated cycles of writing, and general reliability. Unfortunately, I can't now find that discussion in my archives, and I've forgotten where I read it! Hence my shouting from the rooftops. Any suggestions and comments welcome. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 27-Dec-08 Time: 23:59:24 ------------------------------ XFMail ------------------------------

ubuntu and windows Master Boot Record
by Barry Chater 24 Dec '08

24 Dec '08

HI I wonder if you could give me some advice. I am adding a hard drive to my desktop, but since both master and slave connectors are used on the first ide socket on the motherboard. I intend to use the second socket on the motherboard for the new drive, to which i want to install Ubuntu 8.04. windows xp is installed on the hard drive on the other socket, with DVD writer on the slave. I take it that Ubuntu on the second socket will also be a master. I am wondering if Ubuntu will try and overwrite the XP master boot files when i install it. Has anybody had any problems like this. also will tha computer recognise the dualboot or do i have to alter the Bios settings. All the problems i have read about ubuntu overwriting the masterboot files seems to be when two operating systems are on the same hard drive. Am i correct in this? thanks in advance Barry Merry　Ｃｈｒｉｓｔｍａｓ　ｔｏ　ｙｏｕ　ａｌｌ

"thumbnail"-type application
by Ted.Harding＠manchester.ac.uk 23 Dec '08

23 Dec '08

Hi Folks, I'm looking for an application (preferably light-weight) which sould do the following kind of thing. I have a good number of images (*.jpg) stored in sub-directories of sundry directories. The main directory names are rather generic (e.g. a regional location, or names of friends or family). The subdirectories are fairly specific and can descend to very spcific (e.g. a sub-sub-sub-directory with just a date, like "2007.03.05"). I'd like to be able to whistle up screenfuls of thumbnails, possible grouped thematically, with a property like being able to "hover" the mouse over a thumbnail and get a little pop-up with the date of the photo and a brief description. There's an implication, therefore, that there's a kind of basic database engine behind it, together with the "pop-up on hover" capacility. There's no shortage of applications capable of making a bunch of thumbnails (especially from a single directory), but I'm not aware of a light-weight application with the above capability. Gthumb does (clumsily) the sort of thing I'm after, so I could think of using it on machines with Gnome, but not, e.g. on KDE machines. Ideally, in a main directory I would do something like find . -name '*.jpg' -print > image.list edit the file image.list to remove uwanted stuff, and then submit this file to the thumbnail viewer. As an example of scale, one major directory has 4 principal subdirectories hanging off it, with sundry sub-dirs of these, and a total of 170 images. Another is similar, with 150 images. On could probably write something suitable in Tcl/Tk, butit would be nice to find one ready-made! Suggestions welcome. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 09-Nov-08 Time: 09:07:15 ------------------------------ XFMail ------------------------------

finally BBC iplayer linux
by Albert Vilella 23 Dec '08

23 Dec '08

Hi everybody, As you may all know by now, we finally have a BBC iPlayer for Linux! I've tried it this afternoon, and started downloading stuff into my Ubuntu for my Christmas journey. Word of caution, the player will complain that you have reached the download limit very soon, unless you go to Settings and define a bigger "Hard disk space allocated". I haven't found any glitches or problems so far, apart from the fact that one cannot download stuff that is older than a given date. I wanted to get the full collection of "Stephen Fry in America" but I can only download the latest one. There is a "reporting participation" in the Settings that I am sure all the Linux users will leave ticked as to show how grateful are we of having a Linux version :-p Cheers, Albert.

Wierd problem when creating new users, .profile and .bashrc not executing
by Chris G 22 Dec '08

22 Dec '08

I have something not right on my xubuntu 8.10 system. When I create new users using 'useradd <username> they are created OK but don't get a home directory. I'm sure the default used to be to create a home directory and to copy its contents from /etc/skel but it's not doing that. If I do 'useradd -m <username>' then I get the files copied from /etc/skel but they don't get executed on logging in to the new account. Even if I log in to the newly created user and try and execute the files I get a really odd error message:- $ . .profile .: 13: .profile: not found $ The file .profile does exist:- $ ls -al total 32 drwxr-xr-x 5 isbd isbd 4096 2008-12-21 20:23 . drwxr-xr-x 10 root root 4096 2008-12-21 20:24 .. -rwxr-xr-x 1 isbd isbd 220 2008-05-12 19:49 .bash_logout -rwxr-xr-x 1 isbd isbd 3115 2008-05-12 19:49 .bashrc drwx------ 5 isbd isbd 4096 2008-12-19 20:13 Mail drwxr-xr-x 2 isbd isbd 4096 2008-12-19 20:11 .mutt drwxr-xr-x 25 isbd users 4096 2008-10-07 19:20 oldIsbd -rwxr-xr-x 1 isbd isbd 675 2008-05-12 19:49 .profile Erk!

Backups via samba share
by Mark Rogers 22 Dec '08

22 Dec '08

I'm sure this should be easy but I'm getting nowhere with Google... I've created a directory, /backup, which contains symlinks to a number of directories I want to backup across the network (eg /var/lib/mysql is symlinked into that dir). I need to create a samba share which provides read access to all files in that directory. So far I have: [backups] comment = Backups force group = root force user = root path = /backups writeable = no .. but the contents of the directories (like /var/lib/mysql) are not accessible.

Camcorders (Linux friendly, of course)
by Steve Fosdick 21 Dec '08

21 Dec '08

Does anyone have any experience of or recommendation for a camcorder? For me the top priority would be able to make backup copies of the video without resorting to proprietary software, i.e. it would need to record on media that be directly read under Linux or use a communication protocol for which there is a Linux implementation. It would also be good if the video/audio codecs used by the camcorder had a Linux implementation, at least for decoding, so that I could edit the video if I want to or watch it on the PC. Of course, if I can not play the video under Linux I would also want some way to be able to transfer it back to the camcorder for watching on the TV should the need arise. TiA, Steve.
