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

This week we'll probably have a chinwag and maybe a demo of the iPlayer / ITV Player stuff and what's required to capture the High Quality flash videos from the beeb site, instead of just the simpler iPhone quality ones. I'll probably rant a bit about my desire for an Android phone, but how the shocking battery life of the T-Mobile G1 is putting me off ... :) Hope to see you there, Peter. ----- Send discussion replies to main(a)lists.alug.org.uk (Reply-To set) Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce

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
