soundrayHi02:35
BigMacHey02:36
soundrayWhat's your chipset02:36
soundray?02:36
BigMacalright so I have a broadcom chipset which I know are a bi*** to get working02:36
soundrayi386 or amd64?02:36
BigMacI have tried following a guide that is made for my laptop, but it is supposedly crap02:37
naliothor powerpc? :P02:37
BigMaci38602:37
soundraynalioth: do you mean that old, not officially supported platform?02:37
soundray;)02:37
BigMacI tried this guide but the first two steps didn't remove ndiswrapper02:38
BigMachttp://ubuntu1501.blogspot.com/2007/01/fixing-wifi-on-dell-1501.html02:38
soundrayBigMac: have you seen this: http://ubuntu.cafuego.net/dists/feisty-cafuego/all/02:38
BigMacthen if you scroll down I followed the poster named c0ld instructions02:39
BigMacusing bcm43xx-fwcutter driver02:39
BigMacno I will check it now02:39
BigMacanything is worth an attempt02:39
soundrayRe. removing ndiswrapper:02:40
soundrayThe kernel module is part of the default install. Make sure it is not listed in /etc/modules02:41
soundrayYou may also want to blacklist it: sudo sh -c 'echo blacklist ndiswrapper >/etc/modprobe.d/blacklist-ndiswrapper'02:42
soundrayAlthough that's probably overkill02:42
soundrayBut you do want to be sure that the rmmod worked.02:42
BigMacthe rmmod did nothing02:42
BigMacgave an error if I recall02:42
soundraylsmod | grep -q ^ndiswrapper && echo ndiswrapper is still loaded02:43
BigMacdidn't echo anything to me02:43
BigMacand I don't see a modules folder in etc02:44
soundrayIt's a file, and I'd be surprised if you didn't have it at all...02:44
BigMacI can paste the output to pastebin, but nothing was output from that snipper02:45
BigMacsnippet02:45
soundrayHow about cat /etc/modules ?02:45
BigMachttp://rafb.net/p/O3ASlr23.html02:47
soundrayFine02:47
BigMacshould I run the commands on that site you linked me to?02:47
soundrayIt looks to me like the firmware on that site should be the same as the firmware you've already prepared with fwcutter02:48
BigMacOk so what should I be doing02:49
soundrayTry again02:50
soundraybut don't disable the connections like c0ld says02:50
soundraySet them to "Roaming mode" if you want to set it up through networkmanager02:51
BigMacI didn't get that far02:52
BigMacI just went through 1-302:52
BigMacclicked my network02:52
BigMacand it wouldn't connect02:52
BigMacSO I should disable everything?02:52
soundrayNo, read what I said02:53
BigMacok02:53
BigMacsorry I don't know where to adjust those settings, I looked in network tools02:54
soundrayOne above, in Networking02:55
BigMacIt says roaming mode enabled already02:56
soundrayThat's good then02:56
BigMacok02:56
BigMacso what else should I be doing02:57
soundrayCan you do a iwlist ap02:57
BigMacsurr02:57
BigMacsure02:57
soundrayWhat's your interface name?02:57
BigMachttp://rafb.net/p/rUDts424.html02:58
soundrayI see, you haven't got a wireless device yet02:58
BigMacMy SSID? Otherwise I don't know what you mean02:58
soundrayYou have two wired Ethernet sockets?02:59
BigMacI am not sure what you mean02:59
BigMacSorry I am usually not this computer illiterate03:00
BigMacI do have a built in wifi card, and I have one ethernet port on the back03:00
soundrayAre you connected through the Ethernet right now?03:01
BigMacYup03:01
soundrayIs that eth0?03:01
BigMacyes03:01
soundrayHave you got the bcm43xx module loaded? Check with03:03
soundraylsmod | grep ^bcm03:03

BigMachttp://rafb.net/p/KXovG972.html03:05
soundrayThe driver is loaded, then03:06
BigMac?03:07
BigMacSHouldn't it be working then03:07
soundrayBTW, I don't mind you pasting a few lines here. It's the main channel where pasting can be a major problem.03:07
BigMacOh ok03:07
soundrayI don't know, I'm trying the same thing here, and it doesn't work, either...03:07
soundrayDriver loads, but no new interface appears03:08
BigMachmm03:08
BigMacPerhaps I should try the actual driver in that guide, but the first 2 commands do nothing03:09
soundrayThe ones to remove ndiswrapper?03:10
BigMacyah03:11
soundrayThe rmmod command worked. You have no ndiswrapper module now.03:12
BigMacok03:12
BigMacso should I try the guide all the way through then report back03:12
soundrayTo check whether ndiswrapper-utils is installed, do a03:12
BigMacor do you think it is not worth it03:12
soundraydpkg -l ndiswr*03:12
soundrayDifficult question03:13

BigMacIt is just irritating knowing that wifi does work on my laptop, I like ubuntu way more then windows for coding, but yet I have never been able to get wireless working03:14
soundrayYou've successully removed that package03:16
BigMacok03:16
BigMacso continue the guide?03:16
soundrayI don't know03:17
soundrayIt would be nicer to get it to work without ndiswrapper03:18
soundrayand without bypassing the package system as well03:18
BigMacSure but I would rather have wifi with ndiswrapper than no wifi03:18
BigMacIf I can't get it working without it03:18
soundrayI can see that.03:19
BigMacBut if you have more ideas, please go ahead, I am just saying if you are tapped on ideas then i can resort to this03:20
soundrayBut I have to let you try without me, I need a bit of sleep now03:20
soundrayI've been searching the web up and down while we were chatting, but haven't found anything useful03:21
BigMacok I guess I will try and really hope it works03:22
BigMacif not I find somebody else who can help03:22
soundrayGood luck03:22
soundrayBigMac: one more thing03:24
soundraylspci | grep Broadcom03:24
soundrayWhat does that give you?03:25
BigMacmoyers@moyLAPTOP:~$ lspci | grep Broadcom03:26

BigMac08:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)03:26
soundrayYes, it looks like those instructions apply03:29
soundrayI just found that for my device (4328) there just isn't a driver at all yet.03:30
soundrayNevermind03:30
soundraySee you later03:30

soundrayeAi: let's start with grub06:53
eAiok06:53
soundrayTo simplify things a little, there are two parts to it.06:53
soundrayOne is a tiny program that fits into the master boot record of a hard disk drive.06:53
eAiyep06:54
eAistage1 right?06:54
soundrayYes06:54
soundrayThe MBR is outside of all partitions. In fact, I think it contains the partition table as well.06:54
soundrayThat part of grub needs to reference the next stage, 1.5.06:55
eAiok06:55
soundrayOr is it stage2, I get confused.06:55
soundrayIt doesn't matter.06:56
soundrayWhat matters is that stage 1 needs a pointer to what comes next, so it can load it off the disk.06:56
eAiok06:56
soundrayThat's what goes into the /grub subdirectory of your /boot partition.06:57
soundrayOnce that part is loaded, it goes on to load a kernel. At this point, grub is still dependent on BIOS information.06:58
soundrayWhich is why your first attempt with the USB failed.06:58
eAiok06:58
soundrayNow let's make a quick digression into partition tables.06:58
soundrayYou can have a maximum of four primary partitions on a disk, *or* up to three primaries plus an extended partition.06:59
soundrayThe extended partition can contain logical ones.06:59
soundrayfdisk shows all partitions, including the extended one. Some other programs don't. Hence the discrepancy between three and four partitions that you see.07:00
eAiok07:01
soundrayGiven that you have a new /dev/sda6, I presume you have one primary partition, one extended one and two logicals inside the extended.07:01
eAi   Device Boot      Start         End      Blocks   Id  System07:02
eAi/dev/sda1   *           1        5101    40973751    c  W95 FAT32 (LBA)07:02
eAi/dev/sda2            5102        7296    17631337+   f  W95 Ext'd (LBA)07:02
eAi/dev/sda5            5102        7125    16257748+   7  HPFS/NTFS07:02
eAi/dev/sda6            7126        7296     1373526   83  Linux07:02
soundrayYes, that's what I thought. sda5 and sda6 are the logical ones inside sda207:02
eAiok07:03
soundrayThe next step is to copy the required data to your /dev/sda607:03
soundrayHow we do this depends on how you are currently set up. ?07:03
soundrayRunning Windows right now?07:03
eAino, Ubuntu live cd07:04
soundrayeAi: okay, that's where you ran gparted from, correct?07:04
eAiyes07:04
soundrayBTW, what version of ubuntu?07:05
eAi7.0407:05
soundrayDid you have to apt-get install gparted?07:05
eAino07:05
eAiwas in the System->Administration menu07:06
soundrayIt's included, that's what I thought. Someone claimed the opposite yesterday.07:06
soundrayNm07:06
eAiwell, its fairly obvious, right there at the top07:06
soundrayWhat do you get from a 'sudo mount /dev/sda6 /mnt'? I'm hoping for silence.07:06
eAicorrect07:08
eAinothing07:08
soundrayDo a "sudo sh -c 'date >/mnt/datelabel' " to see if you can write to it07:09
soundrayShould be silent, too.07:09
eAisilent07:10
soundrayWhat's the partition name of your ubuntu installation, ie. external hard disk?07:10
eAi/dev/sdb207:11
soundrayeAi: we need to mount that to another mount point.07:12
soundraysudo mkdir /media/sdb207:12
soundraymount /dev/sdb2 /media/sdb207:12
soundrayshould both be silent07:12
soundraysorry07:13
soundraysudo mount /dev/sdb2 /media/sdb207:13
eAiok, done07:13
soundrayNow we need to copy the whole /boot directory contents to the new partition.07:13
soundraysudo cp -a /boot/* /mnt/07:14
soundrayactually...07:14
soundraysudo cp -av /boot/* /mnt/07:14
soundrayThat way you'll know what's going on07:14
eAiok, done07:14
soundrayNow the Ubuntu installation needs to know about the new location of the /boot data07:15
eAiok07:16
soundrayecho '/dev/sda6 /boot ext3 defaults 0 2' | sudo tee -a /media/sdb2/etc/fstab'07:16
soundraybefore you do that...07:17
soundraysudo cp /media/sdb2/etc/fstab /media/sdb2/etc/fstab-backup07:17
soundrayjust to be safe ;)07:17
eAihm07:19
eAithat gives a > prompt07:19
soundraymy fault07:19
soundrayCtrl-C that07:19
soundraythen arrow-up and remove the quote mark from the end.07:19
eAiah ok07:20
eAiyeah it just echoed out that part in quotes to the console07:21
soundrayDo a cat /media/sdb2/etc/fstab and see if the new line is there07:21
eAiyeah it is07:22
eAitheres 5 uncommented lines07:22
soundrayGood. Next step is to adapt the grub configuration to the new location.07:22
eAiok07:23
soundrayCould you paste the whole /mnt/grub/menu.lst to http://paste.ubuntu-nl.org07:23
soundrayand give me the URL07:25
eAisure07:25
eAiwell, its empty07:25
eAiwhich makes that kind of redundant ;)07:26
soundrayWhat about07:26
soundrayls /mnt/grub07:26
soundrayis that empty, too?07:26
eAidevice.map07:26
soundrayIs that all?07:26
eAiyes07:26
soundrayls /media/sdb2/boot/07:27

eAione sec07:33
eAihttp://paste.ubuntu-nl.org/20519/07:36
soundrayI'll go through that, edit it in a few places and paste it back. Be patient pls ;)07:37
eAiof course :)07:37
eAithanks btw, really helpful07:37
soundrayeAi: http://paste.ubuntu-nl.org/20521/07:42
soundrayI hope these are right. Make a backup of the existing menu.lst for reference.07:42
soundrayYou'll see that I put (hd0,5), this is the grub name of your /dev/sda607:43
eAiyeah I saw07:44
eAicopied in07:44
soundrayWe should be ready to put grub in the MBR now.07:44
soundraysudo grub-install --root-directory=/mnt /dev/sda07:45
soundrayAny errors?07:45
soundrayoops07:46
soundrayHave you done that already?07:47
eAiInstallation finished. No error reported.07:47
eAiThis is the contents of the device map /mnt/boot/grub/device.map.07:47
eAiCheck if this is correct or not. If any of the lines is incorrect,07:47
eAifix it and re-run the script `grub-install'.07:47
eAi(fd0)   /dev/fd007:47
eAi(hd0)   /dev/sda07:47
eAi(hd1)   /dev/sdb07:47
soundrayI see07:47
eAithat right?07:48
soundrayThe problem now is that grub created a boot directory inside /mnt, which itself is later going to be /boot07:48
soundrayNot a problem, let's sideline that new directory07:49
soundraysudo mv /mnt/boot /mnt/boot-mistake07:49
soundrayThen create a symbolic link in /mnt named boot, pointing to itself07:49
soundraycd /mnt ; sudo ln -sf . boot07:50
soundrayThen redo the grub-install07:50
eAidone07:50
soundraysudo grub-install --root-directory=/mnt /dev/sda07:50
eAiInstallation finished. No error reported.07:50
eAiThis is the contents of the device map /mnt/boot/grub/device.map.07:50
eAiCheck if this is correct or not. If any of the lines is incorrect,07:50
eAifix it and re-run the script `grub-install'.07:50
eAi(hd0)   /dev/sda07:50
eAi(hd1)   /dev/sdb07:50
soundrayHmm, it's strange that it dropped the fd0 now07:51
soundrayNot a problem, you're not booting from floppy.07:51
eAidon't even have a floppy drive07:51
soundrayLet's think this through now07:52
soundrayGrub will load from /dev/sda and load its config etc. from /dev/sda607:52
soundrayThen it'll boot the kernel...07:52
soundrayoops07:52
eAiremember I still want to be able to boot Windows sometimes ;)07:53
soundrayThat's not a problem, grub knows all about your Vista ;)07:53
soundrayBut we need to change the location of the kernel back to /boot/... now07:53
soundraywhich means I have to give you another menu.lst07:54
soundrayhttp://paste.ubuntu-nl.org/20522/07:55
soundrayThis needs to go to /mnt/grub/menu.lst again07:55
soundrayOkay, now the kernel knows where to find itself, so to speak, once grub loads it.07:56
eAicopied that in07:56
soundrayI think it's done. Wanna try to reboot?07:56
eAiok :)07:59
eAiif it doesn't work I'll have to reboot using the live cd and install xchat again07:59
eAiso I may be some time...07:59
soundrayeAi: either that, or connect with gaim instead (should be on the CD already)07:59
eAiok07:59
eAiI'll be back!08:00

eAiit worked!08:08
soundrayExcellent.08:08
eAithanks a lot :)08:08
soundrayHave you tried booting your horrible closed source OS, too?08:09
eAihaven't tested if windows still works08:09
eAino08:09
eAii've actually got Vista and XP installed, but I never use Vista08:09
eAisomeone gave it to me free ;)08:09
soundrayWell, I trust that it'll work. If not, you can always ask again on the main channel08:09
eAiok08:10
soundrayAre you sorted then? ;)08:10
eAiwell a few other questions08:11
soundrayI'm all eyes08:11
eAilike, is there a way to get double-tap (on the laptop's trackpad) to work for dragging?08:11
eAiits hardly major, but it'd be useful08:12
soundrayeAi: probably. It worked out of the box for me, but you may have to configure the synaptics driver.08:12
soundraygsynaptics is a useful frontend.08:12
eAiok08:13
eAigparted isn't installed by default08:13
eAiit is on the live cd though08:13
eAialso, is it just me, or does the return/enter key not always work to click the default button08:14
eAi(the glowing one)08:14
soundrayeAi: that's just you...08:14
eAistrange08:15
eAiit keeps happening08:15
soundrayeAi: I'm not sure, I don't get this problem.08:15
soundrayDo you mean dialog buttons, like OK/Cancel, or menus as well?08:15
eAiworks fine selecting menu items08:15
=== n2diy [n=darryl@66.212.43.248] has joined #ubuntu-classroom
eAibut for example, if I select a package in the Synaptic Package Manager08:15
eAiand try to install it08:16
eAiI get the "Apple the following change" dialog08:16
eAiand pressing return won't do "Apply"08:16
soundrayeAi: maybe it's not just you08:16
soundrayI tend to use the keyboard for command line work, and the mouse for GUIs08:17
eAiwell, I avoid the mouse as much as I can on my laptop08:17
soundrayTry space if return doesn't do what you expect08:17
eAiwhen I don't have a mouse connected08:17
eAispace didn't work08:17
eAitab -> enter worked08:17
eAi(selecting the checkbox)08:17
eAiwhich suggests that whatever is selected by default is not passing the keystroke correctly08:18
eAianyway08:18
eAii'll live ;)08:18
eAiwheres xorg.conf?08:18
soundray/etc/X1108:19
eAithat gsynaptics app says I've got to set SHMConfig to true08:20
eAibut I'm not sure what section that should be in08:21
eAiand SHMConfig isn't currently in there08:21
eAiI don't have a Synaptics Touchpad item which one site thinks I maybe should08:23
soundrayhttp://ubuntuforums.org/showthread.php?p=97542108:24
soundraylook at post #808:24
eAido I have to restart X after I change it?08:25
soundrayeAi: yes08:25
eAicontrol + alt + backspace?08:26
=== eAi [n=ed@85-211-194-40.dyn.gotadsl.co.uk] has joined #ubuntu-classroom
eAidoesn't work :(08:28
soundrayeAi: you have to reference that InputDevice where the current one is also referenced08:31
soundrayin Section ServerLayout08:31
eAiadd an InputDevice "Synaptics Touchpad"08:32
eAi?08:32
soundrayYes08:33
eAiok, trying that08:33
soundrayMake sure it exactly matches the Identifier.08:33
=== eAi [n=ed@85-211-194-40.dyn.gotadsl.co.uk] has joined #ubuntu-classroom
eAiwell that fixed it :)08:34
eAitap and drag works :)08:34
soundrayHooray!08:34
eAiand the config works :)08:34
eAiconfig should really be part of ubuntu :)08:34
eAijudging by the number of posts there are about this kind of thing08:35
soundrayDo you mean gsynaptics?08:35
eAiyes08:35
eAiand whatever is required to make it "just work" :)08:36
eAiwell, thanks very much for helping me with this08:37
soundrayYw08:37
eAinow, all this stuff has made me forget to eat :(08:38
eAiheres a quick question - whats the best way to mount an SMB share?08:40
soundrayeAi: that's not a quick question ;)08:45
soundrayeAi: try "Places - Connect to server"08:46
soundrayeAi: if you want a permanent mount, add it to /etc/fstab. I'll give you an example line from mine:08:46
soundray/fsg/media /var/lib/media      cifs        credentials=/root/.creds,uid=1000,gid=1000  0       108:47
eAiif that fails to mount, will it cause any problems?08:47
eAi(e.g. if the laptop is off the network)08:47
soundrayeAi: yes08:48
soundrayAfter gid=1000, you can add ',noauto' (no space)08:48
soundrayThen you can mount the share when needed with08:48
soundraysudo mount /var/lib/media08:49
eAihm ok08:49
eAihow can I enable ntfs write?08:49
eAijust install the ntfs-3g package?08:49
eAior is it more complex?08:49

soundrayI don't know...08:50
soundray!ntfs-3g08:50
ubotuntfs-3g is a Linux driver which allows read/write access to NTFS partitions. Installation instructions at https://help.ubuntu.com/community/MountingWindowsPartitions08:50
soundrayThat may help08:51
soundrayI don't have any ntfs partitions on my main machines :)08:51

soundrayAre you undergraduate still?09:10
eAiyes, second year09:10
eAibut strangely I still find I haven't really learnt much I didn't know before I started it ;)09:10
eAiprobably because I wasted most of my school life in front of a computer09:11
soundrayWell, I can tell you your type is in demand in my arena09:11
eAiwhats that exactly?09:12
soundrayExtracting information from e.g. 3D brain images acquired with MRI that isn't readily visible on 2D sections09:13
eAidata visualisation kind of?09:14
soundrayYes, that comes into it09:14
eAior more focused on getting the information than displaying it?09:14
soundrayBut also data mining, feature extraction, statistical functional mapping, all of that09:15
eAisounds interesting09:15
eAiI imagine theres lots of demand for that for all sorts of things09:16
soundrayIf you're interested in a summer project or similar in that vein at any stage, drop me an email09:16
eAilike satellite images etc?09:16
soundrayIt's my nickname at imperial dot aycee dot ukay ;)09:17
