  • X doesn't find nvidia module when installing developer driver

    - by Nils
    I just downloaded the developer driver from Nvidia's CUDA Zone. Executed it and typed in restart gdm and the it worked. However after rebooting X didn't come up (xorg log), to fix it I can simply rerun the installer and the restart gdm again. What I don't understand is where it breaks and why X11 doesn't find the module?! I removed all (I think..) of the Nvidia packages which can with Ubuntu 10.10. I've also googled a bit and found some HOWTOs about manually installing the Nvidia driver. However all of them were for an earlier version of Ubuntu. Please do not respond telling me I should use the proprietary Nvidia driver supplied by Ubuntu, because I need the development drivers.

  • initramfs - Unable to find a medium containing a live file system

    - by LittleBobbyTables
    I'm desperately trying to install ubuntu 12.10 64bit on my new Ultrabook. Its a Sony T13 with 8gb ram, 256gb ssd, i7, windows 8. I have an extra partition, D: "UBUNTU" already created with about 30gb space using FAT32. Ubuntu is MD5 checked, on a previously working USB stick using UNetBootin. Grub loads fine When I ask to test out Ubuntu ("Try ubuntu without installing") it shows the purple loading screen for a bit then brings up this error in a busybox terminal: initramfs - Unable to find a medium containing a live file system Things I've tried that don't work: Different versions of Linux (Fedora, Arch, SL, even gParted) Using USB2/3 - No difference Legacy or UEFI - different interface, but same error BIOS has no option for anything "ACHI" related I have read through tons of other people having this problem and diligently tried all the above solutions, with no luck.

  • Gnome Classic U 11.04 trash not working, can't find my trash dir

    - by Bruce Salem
    I did an upgrade from U 10.10 to U 11.04. I can't upgrade further because Upgrade Manager says that there are unsupported packages. How do I find them? A more immediate problem is that trash stopped working even though "/.share/local/Trash is getting files removed by the file manager. The trash icon on the lower panel fails after having done the upgrade from Gnome 2 to Unity and using Gnome Classic, says "No Such File or Directory". File Operations says it is looking at "/". How do I reconfigure the trash icon to use my local trash dir? The trash dir is there, has the right permissons, I can "rm" the dir tree there, and recreate it by moving files to the trash from the file manager.

  • How to find Sub-trees in non-binary tree

    - by kenny
    I have a non-binary tree. I want to find all "sub-trees" that are connected to root. Sub-tree is a a link group of tree nodes. every group is colored in it's own color. What would be be the best approach? Run recursion down and up for every node? The data structure of every treenode is a list of children, list of parents. (the type of children and parents are treenodes) Clarification: Group defined if there is a kind of "closure" between nodes where root itself is not part of the closure. As you can see from the graph you can't travel from pink to other nodes (you CAN NOT use root). From brown node you can travel to it's child so this form another group. Finally you can travel from any cyan node to other cyan nodes so the form another group

  • Can't find ALL wireless networks, just my neighbours

    - by motoringeek
    Been playing with live discs since 10.10 but now have gone ahead and dual booted. I have a Acer 5742z with a Nplify 802.11b/g/n wireless connection. The install went well and drivers seem to be working. BUT, although wireless detects some local networks it doesn't find mine. I have WPA-PSK security on my modem, could this be the problem?? I don't want to change my modem settings as all my other WIFI devices are contected to it. So I need help in finding my home network. A step by step guide would be useful. I am using Windows 7 now to write this but would love it if I could use Ubuntu online. I only can when I connect an Ethernet cable. Thanks in advance.

    - by explorest
    I have setup an ideal, quiet, non-interrupting environment at home. I am extremely productive here. I dont want to leave my home, not my room, not even my couch. How/where do I find work online so that I don't have to travel to it? Kindly post about your own personal experiences. Have you done it full time from home? Where and how? I am outside United States in a third world country so a lower pay is not an issue. The issue is the work-enviroment.

  • The right way to find a SPUser in SharePoint 2013

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information Obvious stuff out of the way, SharePoint 2013 is claims and claims only. If you’re still pimping classic windows identities, you’re a fool. But this creates an interesting wrinkle. How the hell is one supposed to find a SPUser? This, especially given that a user id now looks like this - i:0#.w|ws\administrator .. all of those have a meaning .. i stands for identity 0 is the zero’th registered claims provider w before the pipe is windows and after pipe is the final username. What if I had a hotmail account called ws\administrator? You see, browsing through web.SiteUsers, is no longer enough. Not only is it error prone, it won’t work for any other identity type besides Windows. So what is a poor SharePoint developer to do? Easy. Use the cod below instead, Read full article ....

  • Find "secret" port number

    - by CJ Sculti
    this may be kind of an odd question. My friend has challenged me. So somehow, he change the "port" of his site to 31337. If you just go to domain.com, you get redirected to google, to access the real site you go to domain.com:31337. He is going to change it again and he is challenging me to find out which port it is. Is this possible without guessing? Hopefully someone can help! Thanks. Oh, and is this the right stack exchange site to post this on...

    - by abhi_nash
    My girlfriend had her Dell Pre-Installed with Windows Vista when she bought it,then she upgraded it to Windows 7 and then 8.Since she wanted an Operating System which is fast and powerful i suggested Ubuntu for her.She runs a Dell Inspiron 1420 with 2 gigs of ram and an Nvdia 8400M GS,though the laptop is a bit old,it does her things like a dream. So,I have used a Flash Drive(8 Gigs) to install Ubuntu 13.04 on her system and used "Overwrite the Windows 8 OS".Then afterwards when I logged in I can't find any of her files which was on her WIndows 8 installation. Anyone know a work around with this?!

  • How to Find Your Lost Android Phone, Even if You Never Set Up a Tracking App

    - by Chris Hoffman
    Android doesn’t come with a “find my Android” feature, so there’s no official way to track your phone if you lose it. You should prepare your phone for loss by setting up such a tracking app — but what if you didn’t? Your first instinct may be to download Lookout’s Plan B, which has been the go-to app for this purpose. However, Plan B only runs on Android 2.3 Gingerbread and lower, so modern Android phones will require a new solution. If you are still running 2.3 or lower, you should definitely check it out, but everybody else can keep reading.

  • How to find the occurrence of particular character in string - CHARINDEX

    - by Vipin
    Many times while writing SQL, we need to find if particular character is present in the column data. SQL server possesses an in-built function to do this job - CHARINDEX(character_to_search, string, [starting_position]) Returns the position of the first occurrence of the character in the string. NOTE - index starts with 1. So, if character is at the starting position, this function would return 1. Returns 0 if character is not found. Returns 0 if 'string' is empty. Returns NULL if string is NULL. A working example of the function is SELECT CHARINDEX('a', fname) a_First_occurence, CHARINDEX('a', fname, CHARINDEX('a', fname)) a_Second_occurrence FROM Users WHERE fname = 'aka unknown' OUTPUT ------- a_First_occurence a_Second_occurrence 1 3

  • Find visitors to multiple subdomains on single visit with Google Analytics

    - by mrwweb
    I'm working on a site that has quite the backlog of Google Analytics data for their site network. One of our big questions is whether people enter on one site and move to another (and if so, of course, how do these visits differ from single site visits). The hostname report (Audience Network Hostname) shows all the host names and I've setup Advanced Segments to get site-specific data. That all works great, but I'm really having a hard time figuring out how to find visits to multiple sites as defined by visiting more than one subdomain or the root site and one or more subdomains. I do see that other hostnames somehow come through when I apply one of the segments to the host name report. Which I can't say I expected. Is that the best way to see if people are visiting 2+ sites?

  • Find out if there is a local user logged in when logging in over ssh

    - by sebastiangeiger
    I need to run some calculations on a machine that I can only access remotely but also serves as a work station. There are many of them and I want to pick a "free" one. Free means in this case that no one is logged in locally. My first try was the who command, but for some reason it only lists "selected" users and I can't really find out how they are selected. Next try: ps aux | cut -d " " -f1 | sort | uniq: better showing a bunch of demons but also the local user that was not displayed by who. My current solution is to go in and do ps aux | grep "gnome-session" which is better but still gives me a lot of junk. Ideally I am looking for something that I can include in my ssh profile that warns me about (active) local users when I log in.

  • Why does update-grub not find ubuntu 11.10?

    - by Klaynos
    I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks

  • Ubuntu doesn't find hdds with higher clock rates

    - by user136243
    I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

  • Can you find the problem in my boot-info

    - by erich
    I'm trying to install Ubuntu 12.04 for two days now. Thats something pretty strange because normally thats done in about half an hour. It doesn't boot whatever I try. I got several different types of not-booting until now. All without significant error messages. Now that I'm running out of ideas I thought maybe one of you is able to find my mistake. The boot info is at http://paste.ubuntu.com/1265205/ If you need any other information I'd be happy to provide it.

  • Find angle for projectile to meet target in parabolic arc

    - by TheBroodian
    I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)? The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?

  • Ways to find a tutor for 1st year University student

    - by Craig H
    I tried searching here (and SO) without much luck. I also stared at the yellow box to the right and think this question is relatively on topic and can be answered. A co-worker asked me if I had any suggestions for how to find a tutor for his son. In this specific case, it was for Eclipse and Java, but it got me thinking about good general strategies one could use in situations like this. He preferred a local 1-to-1, but I suppose online might be a reasonable (or perhaps more likely) alternative. Any suggested strategies?

  • Grub errors during UEFI dual boot for Windows 8 (can't find command 'drivemap')

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the GRUB menu, these two errors show: can't find command 'drivemap' and invalid EFI file path and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!
