  • Laptop screen brightness stuck

    - by Bart van Heukelom
    I can no longer adjust the brightness of my laptop screen, it's stuck at the lowest. In Linux, the brightness adjustment keys (Fn + F4/F5) still work, since a brightness popup shows and the meter bar changes, but it does this in a strange way. Starting at 100%, each successive press of the "lower brightness" button moves the bar to: 67% 50% 0% 26% 12% Or another random pattern like that. The problem is not Linux however, since I can't change the brightness from Windows (7) either. Where do I even begin to look? Since the problem does not seem be OS-specific, I've searched in the BIOS, but it has no option like that. How did this happen? I think it's been this way since when I lowered the brightness to 0%, then pressed the "lower brightness" key again. Not sure about that though.

  • Xerox Workcentre 3119 and Linux

    - by Milan Babuškov
    I'm trying to get Xerox Workcentre 3119 printer to work on Linux. It's a multifunction device (printer and scanner). I run the CUPS web interface at: http://localhost:631/ and it recognizes it on USB port and even suggests Gutenprint driver from the list. When I try to print a test page, the printer goes through "warming up" process (i.e. lights blink and sound is heard) but does not print anything. There are no errors in /var/log/cups/error_log and access_log shows as if everything is ok. The printer works fine in Windows XP. Does anyone have any experience with this printer on Linux?

  • How can I login to Ubuntu using a USB serial port?

    - by marc
    How can enable remote terminal login into Ubuntu 9.10 using a USB serial port? I created device /dev/ttyUSB0 and i want to allow logins using Hyper-Terminal. I found some resources but they are related to real hardware rs232 ports. I can't find any information about USB converter. So far I have established connection between that USB-serial port and my laptop. I can send text to the port (cp sometext.txt /dev/ttyUSB0) and read it using hyperterminal. What do I need to do to enable logins on this port?

  • Sending a Fax without a fax number

    - by Lynda
    I have an HP Officejet 8600 Pro that has faxing capabilities. However I do not send faxes often and I do not need to pay for a dedicated fax number/line. Is there a way to send and receive faxes using the built in wifi without a fax number from the HP? I have seen online services that allow this from the PC, is that the only way to do this? I am using Windows 7 for my OS. EDIT I do not use a regular phone line.

  • Powerpoint template image placeholders can't send to back

    - by Marcus
    We want to be able to set up a PowerPoint 2007 template with a picture frame image. We then want to insert an image in normal view which would appear behind the picture frame image that was put in the template (so it looks logically like a picture in a picture frame). Problem is, when we insert the image in normal view it always appears on top of the picture frame image. It appears that you can't send to back when the other elements are included in a template. Any ideas?

  • Scope of Mainframe Technologies Today?

    - by Vaibhav Bajpai
    I have been recently allocated to training in Mainframe Technologies at my company (where I am currently working as a Trainee). I am slated to learn DB2, JCL, CICS, and Cobol during the programme. I am from a C++ background, and curious how the community here feels of these technologies. I am also curious to know, how mainframe computers fit into today's computing scenario where distributed computing has taken over almost completely.

    Hi All, Hopefully the title isn't funny to be ignored! But I have a genuine interest in understanding what happens when a computer is turned on. i.e. how the computer works on startup, various initializations that take place. For example, is bootstrap loader the first step, when are device drivers loaded etc.. Please guide me to understand. Regards, darkie

    - by altern
    How could I resize or reprocess bunch of videofiles (tv show series) to be able write it on DVD? Total size of all files should be less or equal to the max size of dvd - 4.7G. Is there any kind of program which allows conversion with total filesize adjustement up to defined limit? Is there way to be sure quality will not suffer noticeably after video files adjustments? Maybe there is a software which allows adjusting quality and creating DVD video disk with nifty menu automatically? Any help is appreciated. Thanks!

  • Hotlinking images in Outlook emails

    - by Alexander Voglund
    I want to create an email with a signature that contains an external image. For example, I would like to always include my SuperUser flair in my signature like so: http://superuser.com/users/flair/53525.png This can be done if I insert an image and select the above source. The problem occurs when I copy the image and paste it into the body of a new email. Outlook creates an embedded version and breaks the link to the original email. How can an image be pasted into Outlook and NOT be embedded (ie: the link to the original image is maintained?)

  • Setting up D-link AP2100 as a repeater

    - by Mersan
    Hi, I have two D-Link AP2100, one is connected to a switch (with cable). The second one I would like to use as a repeater, using the WiFi connection to the first and not connected to the switch. Does anyone know first if this is possible, and second and most important, how does one do it. I have tested to set the second AP in repeater-mode, and it is connected to the first, I have full strength to the second one, but I'm not receiving any IP från the DHCP-server, so no access out. Any ideas? /Mersan

  • Coloring The Z Shell[closed]

    - by Richard
    Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt. My .zshrc is Phil's Prompt. My .Xdefaults is: *background: #121212 !black xterm*color0: #353535 xterm*color8: #666666 !red xterm*color1: #AE4747 xterm*color9: #EE6363 !green xterm*color2: #556B2F xterm*color10: #9ACD32 !brown/yellow xterm*color3: #DAA520 xterm*color11: #FFC125 !blue xterm*color4: #6F99B4 xterm*color12: #7C96B0 !magenta xterm*color5: #8B7B8B xterm*color13: #D8BFD8 !cyan xterm*color6: #A7A15E xterm*color14: #F0E68C !white xterm*color7: #DDDDDD xterm*color15: #FFFFFF *foreground: #DDDDDD Help will be appreciated.

  • Degraded RAID5 and no md superblock on one of remaining drive

    - by ark1214
    This is actually on a QNAP TS-509 NAS. The RAID is basically a Linux RAID. The NAS was configured with RAID 5 with 5 drives (/md0 with /dev/sd[abcde]3). At some point, /dev/sde failed and drive was replaced. While rebuilding (and not completed), the NAS rebooted itself and /dev/sdc dropped out of the array. Now the array can't start because essentially 2 drives have dropped out. I disconnected /dev/sde and hoped that /md0 can resume in degraded mode, but no luck.. Further investigation shows that /dev/sdc3 has no md superblock. The data should be good since the array was unable to assemble after /dev/sdc dropped off. All the searches I done showed how to reassemble the array assuming 1 bad drive. But I think I just need to restore the superblock on /dev/sdc3 and that should bring the array up to a degraded mode which will allow me to backup data and then proceed with rebuilding with adding /dev/sde. Any help would be greatly appreciated. mdstat does not show /dev/md0 # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] md5 : active raid1 sdd2[2](S) sdc2[3](S) sdb2[1] sda2[0] 530048 blocks [2/2] [UU] md13 : active raid1 sdd4[3] sdc4[2] sdb4[1] sda4[0] 458880 blocks [5/4] [UUUU_] bitmap: 40/57 pages [160KB], 4KB chunk md9 : active raid1 sdd1[3] sdc1[2] sdb1[1] sda1[0] 530048 blocks [5/4] [UUUU_] bitmap: 33/65 pages [132KB], 4KB chunk mdadm show /dev/md0 is still there # mdadm --examine --scan ARRAY /dev/md9 level=raid1 num-devices=5 UUID=271bf0f7:faf1f2c2:967631a4:3c0fa888 ARRAY /dev/md5 level=raid1 num-devices=2 UUID=0d75de26:0759d153:5524b8ea:86a3ee0d spares=2 ARRAY /dev/md0 level=raid5 num-devices=5 UUID=ce3e369b:4ff9ddd2:3639798a:e3889841 ARRAY /dev/md13 level=raid1 num-devices=5 UUID=7384c159:ea48a152:a1cdc8f2:c8d79a9c With /dev/sde removed, here is the mdadm examine output showing sdc3 has no md superblock # mdadm --examine /dev/sda3 /dev/sda3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff0e - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 0 8 3 0 active sync /dev/sda3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdb3 /dev/sdb3: Magic : a92b4efc Version : 00.90.00 UUID : ce3e369b:4ff9ddd2:3639798a:e3889841 Creation Time : Sat Dec 8 15:01:19 2012 Raid Level : raid5 Used Dev Size : 1463569600 (1395.77 GiB 1498.70 GB) Array Size : 5854278400 (5583.08 GiB 5994.78 GB) Raid Devices : 5 Total Devices : 4 Preferred Minor : 0 Update Time : Sat Dec 8 15:06:17 2012 State : active Active Devices : 4 Working Devices : 4 Failed Devices : 1 Spare Devices : 0 Checksum : d9e9ff20 - correct Events : 0.394 Layout : left-symmetric Chunk Size : 64K Number Major Minor RaidDevice State this 1 8 19 1 active sync /dev/sdb3 0 0 8 3 0 active sync /dev/sda3 1 1 8 19 1 active sync /dev/sdb3 2 2 8 35 2 active sync /dev/sdc3 3 3 8 51 3 active sync /dev/sdd3 4 4 0 0 4 faulty removed [~] # mdadm --examine /dev/sdc3 mdadm: No md superblock detected on /dev/sdc3.

  • Connect devices plugged into Raspberry Pi ethernet to WiFi network

    - by Tom
    I'm just starting out on a mission to learn more about networking and I've followed a tutorial (http://raspberrypihq.com/how-to-turn-a-raspberry-pi-into-a-wifi-router/) to turn my Raspberry Pi into a wifi router. That worked really well so I modified it slightly so that I can use a tethered iphone for the internet connection - I just switched all "eth0" references to "eth1" (the iphone interface) and added a script to set everything up when the phone is plugged in. This setup has freed up the Pi's ethernet port so I'd like to try and take this a step further and allow devices plugged into it to connect to the network. If possible, I'd like to try adding a switch so I can connect multiple devices. I've tried fiddling around with nat & iptables with no luck so my question is, how can I connect devices on eth0 to my wlan network?

  • remove tasksel lamp-server

    - by RickyA
    I was tricked in running "sudo tasksel install lamp-server" on the wrong server (UBUNTU 10.4). Now I am stuck with a system where apache won't start because of a "Address already in use: make_sock: could not bind to address 0.0.0.0:80" error. I now want to remove this task, but documentation on that crappy tasksel says you cant use it to uninstall stuff (!!!???). My question is where can I see what packages it installed, and how can I get rid of a selection of them (apt-get?). I want to keep apache, but mysql, php and the other stuff can go... [edit] I managed to get rid of most of the lamp stack. (/var/logs/dpkg.log is usefull for recently installed packages). However it did something in a configuration somewhere, and now two apache intstances start at boottime. Killing the first one and starting a new one gets rid of the "could not bind at adress..." error. Does anyone know where the startup of the first one is configured?

  • How to change GUI language in Outlook 2007

    - by user1466
    A new guy at work moved in from Denmark, which means that he initially logged in to our Outlook Web Access 2007 from a computer with Danish Windows. As a result, all the objects in the tree-view in Outlook are now in Danish. For example, "Inbox" is called "Indbakke". This prevails, even though he has now logged in locally on his assigned work computer which has English Windows. We're running Exchange 2003, if that matters. How do you change the language of the names of the objects in Outlook 2007? The "Microsoft Office 2007 Language Settings" tool doesn't do this, and I couldn't find anything relevant to this by googling either. In Exchange System Manager there are the "Details Templates" which define these things in different languages, but over on his mailbox there was no configuration option to change which language to use.

  • How to get Virtual PC to recognize MIDI devices?

    - by bparker
    Hey all. I have an XP Pro virtual machine running inside Virtual PC 2007. My host machine is x64 Windows 7. I have a MIDI keyboard hooked up to my machine via a Turtle Beach USB to MIDI 1x1 cable. I have installed the driver and software on my host machine and ran a soundcheck, and everything appears to be working fine. Playback is sent to the MIDI device with no problems. However, when I attempt to install the driver and run a soundcheck in my XP virtual machine, the device is not found. Other USB devices (mouse, keyboard, flash drives) work fine in the virtual machine, but not they MIDI keyboard. I'm not sure what steps to take in order to troubleshoot the and get the VM to start recognizing the MIDI keyboard. Any help or suggestions would be greatly appreciated. Thanks.

    Hello, I would like to be able use some sort of C++ style commenting for Microsoft Word. E.g. If I have // line of text the entire line should be a comment and should appear in a different colour. Same goes for: /* text block */ I would want text block to be in a different colour than my main text. Another feature that would be nice but not necessary for me to have is some sort of a way to quickly strip all the comments. I have no idea how this could be done, if possible. Any ideas? Thanks.

  • Want to install OS from USB instead of CD : How to deal with *.img image files?

    - by claws
    I'm on windows. I'm trying DragonflyBSD operating system. as you can see here: http://www.dragonflybsd.org/download/ there are two kinds of images CD (.iso) and USB (.img) files available for download. I downloaded *.iso and using UNetbootin to make a bootable USB stick. But its taking hell lot of time. Its been 2 hours and its just 50% done(9k of 18k files). I'm really pissed off now! I used *.iso because I didn't know how to deal with *.img files. Will it be quick *.img file? How to use it to make bootable USB?

  • Installing Trac on Windows under Apache 2.2?

    - by Warren P
    Trac is a python-powered bug-tracking and project-management app. According to Trac's wiki, there are several options for installing Trac, a standalone server (tracd), or under a dedicated webserver using one of these options: FastCGI - Not available on windows. mod_wsgi - No version of mod_wsgi available for Apache 2.2.22 and Python 2.7.3-amd64 that actually runs on my system! mod_python - no longer recommended, as mod_python is not actively maintained anymore) CGI -should not be used, as the performance is far from optimal) That leaves me with zero ways to run Trac on Windows. Apache 2.2.22 with ModWSGI loading, crashes the Apache2.2 service on startup without any error logs. Disabling the line in the apache configuration to load mod_wsgi restores sanity. I just want an installation of Trac on windows with Authentication enabled. I am unable to get authenetication to work using basic tracd like this: tracd -p 8000 --basic-auth="c:\tmp,c:\tmp\Passwords.md5.txt,mycompany" c:\tmp\RootFolder And I am unable to get Mod_WSGI installed. I'm going to keep trying to figure out a combination that works, I suspect I should have installed 32 bit python instead of 64 bit python, to start with. Did I do wrong to install Python 64 bit 2.7.3? I tried again with all 32 bit components, and still can't get MOD_WSGI to work with apache 2.2.22. I'm going to try to compile mod_wsgi myself with Visual C++ Express 2010, but it seems to me that it ought to be easier than this to get Trac running on windows, with authentication. Is there a way to run Trac on Windows, under Apache, with authentication? The last "Trac on windows" article died in 2008, leaving only this internet archive link for "Trac on windows" setup.

  • Spots appear in a rectangle area on screen, ubuntu gnome 13.04, nvidia driver

    - by frozen-flame
    I am using Ubuntu Gnome 13.04 with nvidia-310 driver installed. My GPU is GeForce GTX650. Strange spots freqently appear on screen, with following traits: Spots are restricted in one or two rectangle areas at any instant. When typing, the pattern of spots change. Possibly increase, or all disappear when one key pressed. Mouse movement also influences. This problem last within one boot. The only way can I get rid of this problem is to reboot. It can be detected as soon as entering desktop if it appears. Simultaneously, the "power off" option is lost in the top-right menu of Gnome3. Never such problem when using windows 7 on the same computer, neither ubuntu with Nouveou driver. Seldomly, half of the screen become black. I googled a lot. Similar conditions are described, but no confirmed solution. Uninstall-r einstall strategy does not work. Any clue solving this will be appeciated.
