  • How do you stop Linux from re-setting the display brightness?

    - by Shawn J. Goff
    After manually setting the display brightness on my laptop, the system re-sets the value. If the laptop is plugged in, the value is set to full brightness; if it is not plugged in, it is set to dimmer. How do I stop that behavior? Note that I am not talking about what it does in response to the event of plugging in or unplugging my system. It changes on it's own - usually several minutes after I change the brightness value. I have observed this behavior on different systems, different distributions, and different desktop environments.

  • How to boot a Linux live USB on a Mac?

    - by nambuls
    I have a USB stick with a Fedora 11 live environment on it. It's booting fine on 3 PCs where I've tried it. But I can't get it to boot on a Mac (Intel). When pressing the alt key (or command key, I don't remember which one) during startup I can only choose the "Macintosh HD" and the USB stick doesn't appear.

  • Is there a way to save and restore a set of tabs in a linux file manager?

    - by N Rahl
    For a frequent task, I need a file manager window open with about 8 tabs, each a different location. I'd like to be able to open the tabs once and then save them as a "tab set", so that in future sessions, I can simply open a file manager and restore the saved tab set, without having to open each tab manually. I'm running Mint 16 with Thunar, but could use a different file manager if needed. Is there a way to do this?

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • How to scan multiple pages from a book under Linux?

    - by rumtscho
    I want the process to look like: I choose the correct scan settings (dpi, color depth, etc) I lay the first page on the scanner and trigger the process The scanner scans the page and waits for me to position the next page correctly I confirm that the next page is ready for scanning Repeat the above two steps until I tell the scanner that there are no more pages to come The scanner saves everything into a single PDF. I tried both xsane and gscan2pdf. First problem: they want me to know how many pages will be scanned. This is already a nuisance, but I can do the counting if needed. The main problem is that in step 3, the scanner does not pause. It is probably optimised for being fed loose sheets. The next scan process is triggered automatically as soon as the CCD has returned to the start position. The time the scanner needs to return the CCD is very short and I can't turn the page and position the book properly. Is there a software which can do the scan process in the way I described above, or did I just miss a setting available in xsane or gscan2pdf to make the scanner pause? If it makes any difference, the scanner is an Epson Stylus SX620FW, I run it using the manufacturer-provided driver.

  • Alternative to middle click for Linux in Parallels on a MacBook?

    - by Roland Swingler
    I'm running Ubuntu on Parallels on a MacBook, and there is no middle-click on the MacBook trackpad - which is annoying because it means you can't do X's paste action. Is there an alternative? I'm hoping there is a keyboard binding to X's paste or better a way to bind a keyboard key/combination to the middle-click action. Edit: I know about the emulate three-button mouse option, but that won't work for me because the trackpad only allows you to click one button at a time

  • How to disable 3G USB Modem internal storage from being loaded by linux kernel?

    - by Krystian
    Hi, I've got a problem with my 3G modem [Huawei E122]. It has internal storage and kernel assigns a device [/dev/sdX] to it. Because of that, every second time my machine will not boot - kernel panic - as my usb hdd gets assigned /dev/sdb instead of /dev/sda. I cannot use LABEL nor UUID in root= kernel parameter, as it is only available when using initrd, and I can't use it - I am using Debian on my router - mips architecture machine. I have to prevent this from happening, as my router has to start everyday and I have to be sure it works ok. I don't have physical access to restart it when something goes wrong. I don't use my modem internal storage, there's no SD card inserted. However kernel detects the reader and loads it. I can not prevent loading od usb drivers since my hdd is on USB as well. I will appreciate any ideas.

  • Attempt to connect to wireless internet at home and i am asked for User Credentals, nothing I enter works

    - by lucig12
    I just got a new modem and am trying to connect my windows 7 desktop to the new wireless connection. I had no issues on the three previous connections I have used, but for some reason when I click on the icon for Wireless Network Connections, click on my network, it asks for User Credentials. Nothing I type in works. I have tried saving credentials in credentials manager, using my login info, using the network's login info, recreating the network manually, plugging and unplugging my modem, literally every solution on every forum for similar issues. I have no idea what to do now. any ideas?

  • Should I format USB sticks and SD cards to FAT, FAT32, exFAT or NTFS? (Windows files, live Linux distors)

    - by superuser
    Does it depend on the media size which one to chose or on some other parameters? In Windows 7 FAT16 is the default. In pendrivelinux.com's Universal USB Installer FAT32. Which one to chose? How about NTFS for Windows use? How about exFAT? It is tne Microsoft designed filesystem for removable media. Is there a difference in USB sticks and SD cards in this regard? Edit: seeing developments in the other thread, should I still use something like exFAT if I don't want Recycle bins created on every single machine I plug my USB thumb drive in?

  • Anyone experiencing audio issues with VirtualBox on Linux and has a solution?

    - by DoxaLogos
    I've been using Virtualbox (now at 3.0.2) on Kubuntu (now at 9.04) for a while now, and I seem to have a problem when running Windows. Sometime after a while the audio will cut out in Kubuntu. The only way I can get it to recover is to make sure VirtualBox is completely shutdown and either going into multimedia under "system settings" and test the audio or restart. I'm wondering if anyone else here has experienced similar issues and has come up with a more elegant solution. I can't seem to find a reasonable one at virtualbox.org.

  • Linux periodically "losing" ability to connect to server via SSH?

    - by gct
    I know this isn't exactly a programming question, but it popped up in my use of git for programming projects at least. I've got a web server that I use to host my git repos on, but my ubuntu box seems to "lose" the ability to connect to it via SSH. I'll get a "connection refused" error when I try to ssh or use git. Rebooting my local machine will fix the problem, but only temporarily. I can still connect to the web interface just fine, and the problem manifests with other servers as well. I've been working around it by pulling my changes over to my laptop and pushing from there, but that's sub-optimal as you can imagine. Has anyone seen something like this? I'd be tempted to say it's some kind of IP caching problem, but I can't connect even using the IP address of the server directly... Running Ubuntu 9.04

  • I wrote a new X11 keyboard layout file, how do I get my system to recognize it?

    - by grimborg
    I like to configure my keys my way, so I wrote a keyboard symbols file and I put it in /usr/share/X11/xkb/symbols/cat I use it by running setxkbmap cat -variant dvorak (and it works), but it doesn't show up in the console configuration (dpkg-reconfigure console-setup) nor in the Gnome keyboard settings... nor anywhere else, so I have to run setxkbmap every time. I suppose that I have to register it somewhere, but where? Any hints? Thanks!

  • How does one enable --write-mostly with Linux RAID?

    - by user76871
    Unfortunately the mdadm and mdadm.conf man pages are not quite up to par. I would like to enable the --write-mostly flag for my RAID, but neither the man pages nor the internet will tell me how. I am not aware of any place to put default arguments for mdadm, nor aware of when it would be launched and by what. It seems the logical place to add this information is mdadm.conf, but the flag is unmentioned in man mdadm.conf. Where and how can I enable --write-mostly? Thank you.

  • How to know the level of a symlink in linux?

    - by ???
    For example, if a symlink a -> b b -> c c -> d say, the symlink level of a is 3. Then, is there any utility to get this info? And, also I want to get the expansion detail of a symlink, which will show me something like: 1. /abc/xyz is expanded to /abc/xy/z (lrwx--x--x root root) 2. /abc/xy/z is expanded to /abc/xy-1.3.2/z (lrwx--x--x root root) 3. /abc/xy-1.3.2/z is expanded to /abc/xy-1.3.2/z-4.6 (lrwx--x--x root root) 4. /abc/xy-1.3.2/z-4.6 is expanded to /storage/121/43/z_4_6 (lrwx--x--x root root) 5. /storage/121/43/z_4_6 is expanded to /media/kitty_3135/43/z_4_6 (lrwx--x--x root root) So I can diagnostic with the symlinks. Any idea?
