I do have one on order (ie I got to the point of them taking my CC details, so I got past the waiting list to get that far) but no idea when I'll see the device for real. In any case I'd like to have an emulator to play with because that's more portable (ie I can play anywhere I have my laptop without taking hardware with me). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Pointing Device Problems
by Paul Grenyer 12 Apr '12

12 Apr '12

Hi All I've bought a LP107T from August International Ltd pointing device and I'm running Linux Mint. When I plug the device in, the buttons that should move my Libre Office slides actually just move the mouse from left to right. Is there a Linux configuration setting I can adjust to fix this? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer

ALUG Announce Please send announcements to Announce(a)lists.alug.org.uk Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce ----- Hello Norwich Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 12th April at The Coach and Horses (82 Thorpe Road, Norwich, NR1 1BA). The meeting officially starts at 8pm, although some people may arrive earlier. More information on those people can be found on the list and the IRC channel. If you are unsure if you will recognise us then make yourself and your intent to attend known by either posting on list or visiting us on IRC so we can look out for you rather than hiding in the corner. Optionally you could ask at the bar if they know where the geeky computer weirdos are and they'll point you in the right direction (seriously!). Another possibility is look for heaps of electronics on a table that may possibly look like movie props that would used for detonating explosives. Feel free to bring electronics/laptops/gadgets to the meet, you will by no means be alone. Ben Bewick aka Viperfang NB: This mail is automated, please refer to the usual sources for more information.

But I need some more :-( All of the icons on the desktop (I'm the only user) have a red exclamation mark against them and won't run. I've looked at the properties of the icons and they show 'User: 500' and 'Group: chris'. If I look at the /etc/group file, part of it shows this :- chris:x:500: vboxusers:x:502:chris boinc:x:419:chris gnokii:x:418:chris nas:x:501:chris I've looked at various sites online trying to get to grips with groups and users but to no avail. What should I change/add/delete in this file to fix the problem? I think somebody did try to explain this to me in the past but although I kept the mail, I can't get Thunderbird to run so I can't find the relevant mail. The various files in /home/chris show up as 'chris chris' when listed with ls -la I have to confess that it may be caused by a typo on my part! I'm not sure if my account should be Chris or chris so is that likely to be the problem or a red herring?

Does something happen to a WLAN connection every minute?
by Mark Rogers 05 Apr '12

05 Apr '12

I've spent pretty much a whole day on this.... I have a little (ARM-based) Linux (Ubuntu) box connected wirelessly to my LAN. Every minute (via cron) it runs a script which opens a UDP port, then sends a UDP message every second (for 59s) logging the result. For hours I could not work out why more often than not, the script would lock up to 45s then hang - subsequent runs would fail because the port was still held open, and I had to kill the previous instance of the script to get things working again. If I put delays in the script so it didn't do anything for the first (say) 40s, then it still failed at 45s. If I removed the delays so it ran all 60 requests without gaps, they all completed fine (in a couple of seconds). Then on a whim I rebooted and nothing changed, except that the 45s became 38s. Then on another whim, I plugged in a network cable and it's been stable since. So, what might be happening every minute that would cause an existing UDP "connection"[1] to fail? Looking at syslog, the 38s ties in with when NetworkMangler brought the wireless connection up (with dhcp). If it's likely to be hardware specific then I'll probably just change the hardware, but I'd like this to work wirelessly and if there's something happening behind the scenes that could cause this I'd like some clues as to what it might be! [1] Yes, UDP is connectionless so this phrase is a bit meaningless. Hopefully you know what I mean. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Re-posting as my reply wasn't to the group at large last time. Grub2 introduces further complications, and I'd have to refer you to your distribution's documentation on the subject, or a search for "grub2 configuration" - wayne's suggestion to not overwrite /boot with your restore is important.

I have to say I'm getting quite adept at that now though! > Hi Chris, Depending on how your installer has managed the disk partitioning, you will either find the grub configuration in /boot/grub on your root partition, or on its own boot partition (check in the afore-mentioned fstab file for an entry mounted at "/boot"). In here you'll have a grub folder containing menu.lst This config file drives your grub bootloader, its possible that the commands in here are pointing at a uuid or partition thats incorrect - make a note of all the partitions you've installed to, and ensure they appear something like the following for your linux boot entry: title Arch Linux root (hd0,0) kernel /vmlinuz-linux root=/dev/sda3 ro initrd /initramfs-linux.img The important lines are: * root (hd0,0) -> pointing at the first disk, and first partition as the location for the boot files (the grub files and kernels where you found this config file normally - either your root partition or a seperate boot partition) * kernel /vmlinuz-linux root=/dev/sda3 ro -> this is the line which starts the kernel from your boot partition and tells it where to mount its root filesystem (in my case here, my system has created an initial ramdisk and its root partition is /dev/sda3 - partition 3 on my first SATA disk). Hope this helps point you the right direction.

Machine won't boot after re-install
by cdw_alug＠the-walker-household.co.uk 04 Apr '12

04 Apr '12

I did a backup of my machine using tar commands and have then resized the various partitions. I reinstalled the OS from the original DVD and then started to restore the original files, extracting them from the various tar files - I wrote a separate tar file for each of the folders in starting from / such as '/opt-backup.tgz' I took notice of what Brett said last week about not doing a backup of /dev so that should remain untouched from the install. But now having restored everything, it comes up with the message 'No root device "block:/dev/disk/by-uuid/<disk-id here>" found and then 'resume device /dev/disk/by-uuid<another disk-id>' If I start again with the install, which of the various tar files should I *not* restore to avoid this problem ad infinitum? TIA.
