Re: [ubuntu-uk] buying a laptop?
I've had great luck in general with IBM (I guess now Lenovo) thinkpads. They're a bit spendier but. Also have a 3 button mouse. Pretty much everything just works, though I have looked typically to make sure I'm getting the right wifi card, etc. thinkwiki has loads of useful info for anything that doesn't work, but aside from the middle-button-scrolling thing, I've not had to do anything since about 8.04. There have been times when linux has been available, though I think a hidden option. You can often find them online without OS (i.e., if it's an off-lease model or somesuch). -g On 19/01/2011 02:33, Paula wrote: I have a Novatech laptop, two years old, older model. Ubuntu went on no probs and never had any issues re ubuntu - overall its battery catch has broken which is annoying as the battery is prone to drop out. The piano black cases are a tad flimsy and the keyboard's a bit springy. The laptop inside is great though. I asked Novatech before I bought it if it would work with Ubuntu and they got tetchy - they don't test them and it's at your own risk. I googled, couldn't see any probs and there were none. If you want it tested, it's back to LE.

I haven't used one of these machines, but as with most Core i3/i5 systems at the moment, I suspect that you will probably run into this little bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/614238 if you want to use the VGA port. This bug seems to affect any Linux (not just Ubuntu) on any Core i3/5 system that is using the integrated GPU. But it does seem as though there may be fix in the wings... With my Samsung Core i3 lappy, the HDMI port does work OK however (and can be adapted to DVI with a cheapish cable) so it isn't the end of the world. You could always ask Novatech beforehand - they might even offer to take it back if fails to work to your satisfaction, or, if you happen to be near one of their showrooms, you could ask to take along a USB stick and test it before buying? I see no harm in asking at least...

You've just diagnosed the problem. It has nothing to do with the wireless, and has to do with the kernel parameters for maximum TCP and UDP ports (really, NAT settings) or TCP/UDP timeout. On DD-WRT v24, this is set on the Administration tab, Management subtab, bottom of page, IP Filter Settings (adjust these for P2P.

[ubuntu-uk] Custom Live CD
Hi When you boot into a Ubuntu live CD it gives you the option to try out Ubuntu or start the installer. I want to create a customer image that removes that dialog and runs a python script instead. Anyone know how to do this with the UCK? I presume I have to edit some files at the chrooted terminal it gives you.

If you just want to go straight to the installer you can use 'only-ubiquity' as boot option and you won't see a desktop. You can also preseed ubiquity if you want to automate the whole install. Sorry, not so familiar with UCK, perhaps someone else can answer that. I tend to use live-helper for this sort of thing, which you could add a small init script into the live chroot to get it to run a script upon boot.

If you correct this and run the script it produces the desired dialog. Using the UCK I asked for the chroot'd console and followed the tutorial. When I built and ran the live ISO the system booted into the installer dialog. When I clicked try Ubuntu it went back to the loading splash screen and hung.

Re: [ubuntu-uk] netbook wifi traffic disconnects all
Ok it was on it's side, but I put it vertical and I have the same problem. My model is WGR614v6 and the firmware is up to date. I only need one torrent (trisquelgnulinux.iso) for it to drop connection: my wife downloaded some tv series the other day with no problem (via wifi). I recall using the other ubuntu desktop to download more distros with no problems either. So I guess the router can be discarded as the cause of the problem? I'm not really a heavy wifi user: internet radio+ w7 laptop+ ubuntu netbook. I notice that the disconnection occurs when I am in the range of 0.5 MB/s. I have the basic 10Mb package. Thanks for the channel shaping info: so this means that my wireless is forcing it's way to get the most band and then the router disconnects everybody to stop 1 guy hoarding the whole network? I had read about traffic polution. http://en.wikipedia.org/wiki/Wi-Fi#Channel_pollution but that doesn't seem the answer. My wife's wifi seems to do fine. Try: iwconfig wlan0 rate 1M (replace wlan0 with your interface's name) man iwconfig for more options. A ### thanks for that! $iwconfig wlan0 IEEE 802.11bg ESSID:Kamehouse Mode:Managed Frequency:2.462 GHz Access Point: 00:14:6C:7C:48:3C Bit Rate=1 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=53/70 Signal level=-57 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 but when trying to change the rate to auto or 0.5Mb/s it says; $ iwconfig wlan rate 0.5M Error for wireless request Set Bit Rate (8B20) : SET failed on device wlan ; Operation not permitted. Does the above mean that I have a 1Mb/s limit? and I cannot change it? sorry, did a quick search could get nothing. funny enough I did $ iwconfig wlan0 wlan0 IEEE 802.11bg ESSID:Kamehouse Mode:Managed Frequency:2.462 GHz Access Point: 00:14:6C:7C:48:3C Bit Rate=54 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=65/70 Signal level=-45 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 and now said 54Mb/s! but did the comand again and it went back down to 1Mb/s does this mean that multiple bit rates is not supported? have I missed anyone? ## I've a Netgear DG834gt Router with custom firmware, It does the same! With me It's a problem with the way the router handles ports, It only happens when i'm downloading many torrents, causes the routers wireless not respond. My router stands vertically with a 4inch gap all around it in a room with no central heating on (it's around 16c in the room) so don't think it's not an over heating problem. It sounds more like a problem with the drivers of the wireless, Can't remember where I read it but there's something about the number of ports the router can open and the speed the connections are recycled causes the drivers to effectively crash if it happens too quickly. As I said, it only happens with me If I'm downloading multiple torrents and they all try to open more than 256 ports each.. -- Regards Bill Cumming -- Correo enviado desde mi ubuntu netbook -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

I traced this to the channel that I was using. The router defaults to channel 6. I changed to channel 11 and the problem went away. I think that one of my neighbours must have bought a wireless device such as a base station telephone which was swamping the signal for channel 6. It is worth a try as it is simple to change and will not cost you a penny. Barry -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
