  • How do I disable Caps Lock by command line?

    - by Echogene
    For some reason my laptop is stuck in Caps Lock. I have the Caps Lock key mapped by xmodmap to hyper_l, so I don't have a caps_lock key to turn it off. Is there a way I can turn it off by command line? It would be nice if I could reset the lock state without resetting my computer, especially for future reference. This has happened before, but I would like to know now how to do it properly this time.

  • RAID1: can't replace faulty spare (marked again as 'faulty spare' within seconds)

    - by user212475
    I got a problem that I cannot solve: Our fileserver runs XUbuntu and 3 RAID1s. One has a problem since monday: it consists of sdb and sdc. sdb was marked as faulty by mdadm for unknown reasons. I used --remove to remove it from the RAID and then to add it by --add. All was fine, re-syncing started but never got above 0% and after a few seconds, sdb was again marked as 'faulty spare' (and therefore the RAID degraded, but clean). So I saved the first 512 byte of the old sdb to a file, bought a new HDD of same size (4TB), shut down the computer and replaced sdb physically, switched the computer back on and wrote the 512 byte back to the new drive to have the same partition info as the old drive (both are the same type, from same company). But the new drive shows the same behaviour as the old: I can add, re-syncing starts and after a few seconds its marked as 'faulty spare'. Here exactly what i did: mdadm --remove /dev/md/1 /dev/sdb maadm --detail /dev/md/1 gives me: /dev/md/1: Version : 1.2 Creation Time : Sat Jun 8 22:32:05 2013 Raid Level : raid1 Array Size : 3906887360 (3725.90 GiB 4000.65 GB) Used Dev Size : 3906887360 (3725.90 GiB 4000.65 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Thu Nov 7 06:56:13 2013 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : File-Server:1 (local to host File-Server) UUID : 44ed561f:b733e946:e69820f4:aba9b223 Events : 2424 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 32 1 active sync /dev/sdc mdadm --add /dev/md/1 /dev/sdb mdadm --detail /dev/md/1 gives me: Version : 1.2 Creation Time : Sat Jun 8 22:32:05 2013 Raid Level : raid1 Array Size : 3906887360 (3725.90 GiB 4000.65 GB) Used Dev Size : 3906887360 (3725.90 GiB 4000.65 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Thu Nov 7 06:57:49 2013 State : clean, degraded, recovering Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Rebuild Status : 0% complete Name : File-Server:1 (local to host File-Server) UUID : 44ed561f:b733e946:e69820f4:aba9b223 Events : 2431 Number Major Minor RaidDevice State 2 8 16 0 faulty spare rebuilding /dev/sdb 1 8 32 1 active sync /dev/sdc and after a few seconds: /dev/md/1: Version : 1.2 Creation Time : Sat Jun 8 22:32:05 2013 Raid Level : raid1 Array Size : 3906887360 (3725.90 GiB 4000.65 GB) Used Dev Size : 3906887360 (3725.90 GiB 4000.65 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Thu Nov 7 06:57:50 2013 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Name : File-Server:1 (local to host File-Server) UUID : 44ed561f:b733e946:e69820f4:aba9b223 Events : 2436 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 32 1 active sync /dev/sdc 2 8 16 - faulty spare /dev/sdb same behaviour if I zero the superblock (mdadm --zero-superblock /dev/sdb) before adding sdb. I do all commands as root and the system holds 3 more 4TB drives, ie the mainboard can handle them. The old harddrive was checked for errors using badblocks, but all is fine. Does anybody have any idea, what the problem is?

  • How to run software, that is not offered though package managers, that requires ia32-libs

    - by Onno
    I'm trying to install the Arma 2 OA dedicated server on a Virtualbox VM so I can test my own missions in a sandbox environment in a way that lets me offload them to another computer in my network. (The other computer is running the VM, but it's a windows machine, and I didn't want to hassle with its installation) It needs at least 2, and preferably 4GB of ram, so I thought I would install the AMD64 version of ubuntu 13.10 to get this going. 'How do you run a 32-bit program on a 64-bit version of Ubuntu?' already explained how to install 32bit software though apt-get and/or dpkg, but that doesn't apply in this case. The server is offered as a compressed download on the site of BI Studio, the developer of the Arma games. Its installation instructions are obviously slightly out of date with the current state of the art. (probably because the state of the art has been updated quite recently :) ) It states that I have to install ia32-libs, which has now apparently been deprecated. Now I have to find out how to get the right packages installed to make sure that it will run. My experience level is like novice-intermediate when it comes to these issues. I've installed a lot of packages though apt-get; I've solved dependency issues in the past; I haven't installed much software without using package managers. I can handle myself with basic administrative work like editing conf files and such. I have just gone ahead and tried to install it without installing ia32-libs through apt-get but to install gcc to get the libs after all. My reasoning being that gcc will include the files for backward compatibility coding and on linux all libs are (as far as I can tell) installed at a system level in /libs . So far it seems to start up. (I can connect with the game server trough my in-game network browser, so it's communicating) I'm not sure if there's any dependency checking going on when running the game server program, so I'm left with a couple of questions: Does 13.10 catch any calls to ia32libs libraries and translate the calls to the right code on amd64? If it runs, does that mean that all required libraries have been loaded correctly, or is there a change of it crashing later on when a library that was needed is missing after all? Is it necessary to do a workaround such as installing gcc? How do I find out what libraries I might need to run this software? (or any other piece of 32-bit software that isn't offered through a package manager)

    - by user49523
    Currently I don't have any driver available for the laptop that I use , and because of this I only can use Unity 2d and Gnome Panel. I have Ubuntu 11.10 and Ubuntu 12.04 installed and no drivers for both. I would like to use Unity 3d and Gnome Shell..instead of Unity and Gnome Panel or at least have that option even if computer became a little slower. Is there a way of enabling Unity 3d and gnome without any driver had been installed?

  • How to activate a dialogue box on suspend?

    - by don.joey
    I am using 14.04 with unity. Quite regularly it happens to me that I want to shutdown the computer, but in the right corner menu I accidently hit Suspend in stead of Shutdown. Is it possible to add a dialogue box on the suspend menu? So that I don't always have to come back from suspend to finally shutdown afterwards. Or is it possible to make the shutdown button like 3 times bigger than the suspend button?

  • Why aren't web frameworks simple, elegant and fun like programming languages? [on hold]

    - by Ryan
    When I think of pretty much any programming language - like C, C++, PHP, SQL, JavaScript, Python, ActionScript, Haskell, Lua, Lisp, Java, etc - I'm like awesome I would love to develop a computer application using any of those languages. But when I think of web frameworks(I do mostly PHP) - like Cake, CI, Symfony, Laravel, Zend, Drupal, Joomla, Wordpress, Rails, Django, etc - I'm like god no. Why aren't there web frameworks that provide me with simple, fun and powerful constructs like a programming language?

  • Can you still install Ubuntu 10.10 with Wubi?

    - by I Heart Ubuntu
    I am trying to help a friend get set up with Ubuntu and want to recommend Wubi for his install (he is not very computer savvy). I had recently tried the Wubi download from Ubuntu.com and the only option it gave me was to install Natty. Is there any way I can get Wubi to install 10.10 Maverick? Preferably just the EXE file, not having to download an entire disc image as the friend has no idea how to burn discs. Thanks much!
