• Unable to boot into 11.10 in normal (get a black screen) OR recovery (get just a flashing cursor, no cli)

  - by user1092284

  Okay, so I had a dual boot of Tango Studio (based on Ubuntu 10.04) and Windows XP. Yesterday I downloaded the .iso for Ubuntu 11.10 and attempted to install from a USB (my BIOS won't normally boot from USB but I had PLOP boot manager on a CD). I booted up Ubuntu from the USB and then from there formatted the partition with Tango on and installed Ubuntu 11.10. On booting up I came into Grub rescue mode. So I booted up from the USB again and used boot-repair to reinstall Grub. After this I would see the normal Grub menu, but on choosing Ubuntu I would come to a black screen. On choosing recovery mode it would begin starting normally with no obvious errors but instead of coming to a cli I would just get a blank screen with a flashing cursor on the top left, not accepting any input. I have since reformatted and reinstalled from a CD rather than USB and had the exact same problem. I used boot-repair again and the result is the same. Output of the most recent boot-repair is at http://paste.ubuntu.com/869805/ I have also tried editing the ubuntu grub entry and replacing quiet with text nomodeset as I saw in an answer to another question. This got me a bit further - I saw the purple ubuntu loading screen but still came to a blank screen after that. Anyway, in most of the other questions in which that is brought up the user is still able to boot into recovery, while I am not. Can anyone help? Thanks in advance, let me know if there's any more info I need to provide! EDIT FOR MORE INFO: I read something saying it's quiet splash that should be replaced with nomodeset. Earlier I had left splash in the line. So i tried it this way and it froze after displaying the following text: fsck from util-linux 2.19.1 mountall: Plymouth command failed mountall: Disconnected from Plymouth /dev/sda5:clean, 139359/1741488 files, 745830/6961125 blocks From a bit of googling it doesn't look like plymouth is essential, but I've checked and I do have the most current versions of mountall and plymouth installed so I don't know why there's a problem EDIT FOR MORE INFO AGAIN: I used dkpg --reconfigure plymouth cause I saw it mentioned in another forum and it still says plymouth command failed on boot

• Windows 2008 x64 displays SP1 when SP2 is installed

  - by Graham Powell

  After setting up a Windows 2008 x64 server (not R2), I installed a number of Microsoft updates. After installing these updates, the computer reports that it has SP1 installed, not SP2. I believe the culprit is KB917607, which allows Windows 2008 to display .hlp files. Now I have to upgrade Internet Explorer on this server, and it won't install without SP2. I am very leery about reinstalling SP2, as I have installed a large number of post-SP2 updates, and I've had issues after reinstalling SP2 in similar circumstances. How can I fix Windows so it reports the correct service pack?

• Client PC not booting when certain TFT plugged in - TFT or graphics card failure?

  - by Chake

  here comes something quite strange: On a client machine (DELL Vostro 420) we experienced problems when booting: when turning on the machine beeps normal but doesn't display anything and doesn't boot. After some testing I found out, that this only happens if one (of the two) monitors (Iiyama ProLite E2472HDD) is plugged in while booting. If the other monitor (TFT 2) is plugged in everything is fine. Here a small illustration, TFT 1 is the bad guy: TFT 1 | TFT 2 | failure x | x | x x | | x | x | After BIOS-Phase I can safely plug in TFT 1 and everything works just fine. The question is, what can be done to avoide this behavior: Change monitor? (Iiyama ProLite E2472HDD) Change graphics card? (GeForce 9800 GT) Other suggestions?

• How can I have sound output before logging in?

  - by ??O?????

  I have a machine (Ubuntu 11.10) that I would like to have it play audio (typically through an amplifier), but the machine should be headless (where its final placement will be). I will control what is played through ssh. However, there is no sound output until I login to the graphical console. At first I thought it was an issue with pulseaudio, so I promptly removed it to use the default ALSA, but I have the same issues. I ssh to the machine, I run alsamixer and get the typical cannot open mixer: No such file or directory error (while /proc/asound/cards display correctly what I have). If I login on the graphical console, alsamixer works fine in the ssh session, and I have sound output. I logout, and then alsamixer stops working. So something runs (Xsession perhaps?) when I login that enables sound output, and gets disabled when I logout. I remember in older versions of Ubuntu, there was a drum roll when the machine showed the login screen; that is not the case anymore. Perhaps if I somehow can enable that drum roll, I'll have fixed my problem too. In any case, the question I ask is what the title says.

• What Software or tool to ease the building of an eye catching GUI (functional) [closed]

  - by CaBieberach

  I want to make a control panel that opens different files but I'm not sure what would be the right tool/Sw to make this. In the company we have about 30 files that we use almost every day. They are all related to each other. I would like to create a "Control panel" to ease the opening and searching of these files. Kind of a control panel with 30 buttons. The only duty of this control panel is to open one of the file selected by the user. I need this "Control Panel" to: Look GREAT Open very fast Could you please recomend me some tool/Sw to acomplish this. What tool or SW is specially focused to make stunning GUIs? Note: In the company We are all using MS Windos 7. Thanks for the help! EDIT: This would be a Stand alone program installed or saved in a network drive. Each person can open the porgram and it pops the GUI. Not for the web. "Looks GREAT" is definitively a subjective matter. I want something that gives me plenty options to display/modify the objetcs that compose the GUI. So i can experiment and find what looks and works the best.

• Kubuntu never gets to the login screen

  - by searchfgold6789

  I am not sure if Xorg is using the right device... The system in question is an A4-1400 CPU with built-in Radeon Graphics. I added a PCIe Radeon HD 5750, and changed the BIOS so it would use that card automatically. Now it appears that I can see output from the TV plugged into the HDMI port, and boot into recovery mode, but cannot get to a desktop - X doesn't start. It just freezes at the Kubuntu splash screen. I have no idea how to get X to use the proper graphics card. I pasted the Xorg.log to http://paste.ubuntu.com/6261137/. And the Xorg.conf generated by aticonfig --initial is at http://paste.ubuntu.com/6261161/ Also, see lspci and lshw -c display outputs. I can provide more information, but something does tell me X is not using the right graphics card and I've no idea where to begin how to fix it... I faced a similar issue before with another distribution but found no information anywhere on how to make X use a specific graphics card. Or maybe it's not that simple.

• Reverse Proxy (mod_rewrite) and Rails (absolute paths)

  - by SooDesuNe

  I have front end rails app, that reverse proxies to any of a number of backend rails apps depending on URL, for example http://www.my_host.com/app_one reverse proxies to http://www.remote_host_running_app_one.com such that a URL like http://www.my_host.com/app_one/users will display the contents of http://www.remote_host_running_app_one.com/users I have a large, and ever expanding number of backends, so they can not be explicitly listed anywhere other than a database. This is no problem for mod_rewrite using a prg:/ rewrite map reverse proxy. The question is, the urls returned by rails helpers have the form /controller/action making them absolute to the root. This is a problem for the page served by mod_rewrite because links on the proxied page appear as absolute to the domain. i.e.: http://www.my_host.com/app_one/controller/action has links that end up looking like /controller/action/ when they need to look like /app_one/controller/action mod_proxy_html seems like the right idea, but it doesn't seem to be as dynamic as I would need, since the rules need to be hard coded into the config files. Is there a way to fix this server-side, so that the links will be routed correctly?

• Certain sites not working in Firefox, working in IE

  - by PSU_Kardi

  Totally weird thing happening on my PC after I came back from the Holiday shutdown. My homepage by default is google.com/ig but when it opens (in Firefox) the G-Mail panel does not display and eventually times out. I then try to navigate to https://www.gmail.com but that also times out. Thinking maybe work decided to drop the ban-hammer on g-mail I decided to try it in Internet Explorer. Oddly enough it works in IE Any idea on why it works fine in one browser but not the other?

• Second Monitor "Input Not Supported"

  - by Drew

  I have two identical monitors (new Acer s211hl) with a native resolution of 1920x1080. When enabling dual monitor support in Windows 7, the primary monitor works as expected, but the second monitor says, "Input not Supported" and fails to display anything. If I change the resolution of the second monitor to 1440x900, it works as expected. Likewise, if I set it to 1920x1080 with a refresh rate of 30hz, the monitor displays video. However, neither of these are solutions, because the output looks very blurry, and the content is stretched. I am using the following hardware: Monitors: Acer s211hl Motherboard: Asus F1A75M-Pro CPU/GPU: AMD A8-3850 with integrated Radeon HD 6550D graphics I suspect that there is probably an issue with the integrated graphics or motherboard not being able to output to two 1920x1080 monitors, but I am hoping for official confirmation.

• How to show users the reason for a message being bounced or rejected by Postfix?

  - by Ross Bearman

  A user would like to be able to view a web page showing any emails that a Postfix server has either been unable to send, or unable to receive. For example if the user was supposed to receive an email from a third party but it hasn't arrived, they'd be able to check the web page and see a list of emails rejected by Postfix, along with a clear reason as to why. I've been unable to find an existing application that offers this functionality. Does anyone know of any, or is the best way forward to write a script that parses the log and display the results?

• How to make a quiet laptop ? [closed]

  - by psihodelia

  Most modern laptops have very noisy fans. I am looking for a quiet laptop or a small stationary computer which has all its hardware built in a display. Most tasks will be pdf/docs processing, real-time audio processing, web-surfing and skype video chats. Certainly, there is no any fan-less model today; but maybe some of the existed laptops do not switch on their fans so often or implement different solutions? For example, an iPad has no fan at all and it is fast enough for my needs, but it has no normal operating system, so I can't use it for anything but audio chats and web-surfing. Or maybe I can buy a laptop and tweak it to make it absolutely noiseless? Can you recommend me any solution please? Thanks in advance!

• Installed IE8 & SP3 on XP now I can't HTTPS from any browser.

  - by Kevin

  The computer is Windows XP Professional SP3 with IE8. On the Tools Options Connections the "Settings" is GRAYED OUT (I am an admin on the machine) Any browsing of https:// addresses results in IE displaying the following: "this program cannot display the web page" After installing an alternate browser and trying the same https:// address I get a similar error message. I have tried using Compatibility View Settings to for all web pages and this has no effect on the problem. HTTP addresses work fine, I can PING sites such as google.com without issue. Question: What could be preventing me from getting at the settings to check to see if I'm using a proxy? What else could be preventing HTTPS access?

• Explorer.exe - No such interface supported and other issues

  - by tom

  The problem started when I uninstalled my ATI graphics driver and i used a driver cleaner. After i restarted win7 and it got to POST the screen just went completely blank. So i Used system restore from the repair menu to get back on. I found out that if I ran chkdsk the display just goes black after restart on startup and i have to use system restore to get back on windows7 not sure why this is. When i right click desktop and choose 'Screen Resolution' it says No such interface supported. Also when I click items such as device manager in the windows explorer it does not do anything. I have tried re-registering the DLLS but that did not do anything.

• Running Outlook from VB with multiple email addresses [migrated]

  - by Mac

  I am sending emails from my VB6 system and I am having problems with sending a single email to various email addresses. The code is as follows: On Error Resume Next Err.Clear Set oOutLookObject = CreateObject("Outlook.Application") If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If Set oEmailItem = oOutLookObject.CreateItem(0) If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If With oEmailItem .Recipients.Add (SMRecipients) .Subject = SMSubject .Importance = IMPORTANCENORMAL .Body = SMBody For i = 1 To 10 If RTrim(SMAttach(i)) <> "" Then .attachments.Add SMAttach(1) 'i) Else Exit For End If Next i .send End With If Err <> 0 Then MsgBox "Email error. Err = " & Err & " Description = " & Err.Description EmailValid = "N" Exit Function End If ''' .Attachments.Add ("c:\temp\test2.txt") Set oOutLookObject = Nothing I have set SMRecipients to a single email address and it is fine but when I add more addresses seperated by semicolons or spaces it only sends to the original address. My system runs under XP. Another point is that it use to find the addresses in the Outlook Address book and where they wetre not specific enough it would display the matching addresses for selection of the correct one. It no longer does this.

• Battery notification always showing 'xx% remaining' with Windows 7 on an acer Aspire 5590

  - by dindeman

  My battery level always shows up as something like 55% remaining or 63% remaining ...etc despite that it is in fact charging. Additionally it doesn't go any further than 80% remaining even if I keep it in charge forever. This leads me to a side annoying effect which is that I cannot proceed to install Windows 7 Service Pack 1 as its installer requires the laptop to be plugged with a power cord. My laptop is plugged with the power cord but because of the above issue (it doesn't display anything else than the xx% remaining) Windows thinks that the laptop is using its battery and that the power cord is disconnected. I have installed the original acer ePower Management tool that let you configure the power scheme... etc, I was hoping that this would help me circumvent the 80% issue but it doesn't.

• How do I log file system read/writes by filename in Linux?

  - by Casey

  I'm looking for a simple method that will log file system operations. It should display the name of the file being accessed or modified. I'm familiar with powertop, and it appears this works to an extent, in so much that it show the user files that were written to. Is there any other utilities that support this feature. Some of my findings: powertop: best for write access logging, but more focused on CPU activity iotop: shows real time disk access by process, but not file name lsof: shows the open files per process, but not real time file access iostat: shows the real time I/O performance of disk/arrays but does not indicate file or process

• Google Chrome with strange behavior

  - by user72274

  I'm former Chromium-browser user, but after not upgrading the PPA for 2 months, I switched to Google Chrome browser yesterday. Everything is okay, except some strange behavior on some pages and crashing after loading "chrome://" configuration pages. The best known website with strange behavior is youtube, there is a picture what I see: When I open user menu in top right corner, it crashes that way and even after closing the menu, some parts of menu stay display. You may say it's Youtube problem, no, I have this problem at least on three other websites, here it is on Imgur: The problem isn't for the whole side, sometimes it happens from the middle of the screen. The interesting part is that it happens everytime in the same distance from the right border. When I check the DOM elements with the Developer tool, the overlay which shows element's position is rendered how it should be. What is more, if there is anchor after the crashed area, it works after clicking on it. Selecting text in crashed page is impossible. I hope there is enough information to give me an advice, thanks in advance. :) EDIT: Here is what the browser posted in "chrome://gpu-internals/": Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Software animated. WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Problems Detected Accelerated CSS animation has been disabled at the command line.

• Is there a way of disabled byte-range requests in Apache?

  - by Sam Minnée

  I have a web page with a link to a PDF file (target="_blank"). If I click the link, the PDF reader just shows a grey screen within the Firefox browser. If I copy that link and manually open it in a new tab, the PDF will display correctly, and subsequent requests made by clicking the original link now work, suggesting that the problem occurs when loading the file into the cache. It appears as though the Adobe PDF reader plugin is making byte-range requests (I see lots of 206 responses) and I suspect that this may be the cause of the issue. I am running an Apache webserver. Has anyone had problems with Apache and Adobe's byte-range requests? Are there any workarounds? Perhaps a way of configuring Apache to ignore byte-range requests on PDFs?

• How should I structure a site with content dependent on visitor type (not user)?

  - by Pedr

  I have a website that displays different content depending on two selections made by a visitor: Whether they are a teacher or student, and their learning level (from 4 options). Everything is public and they don't need to authenticate to access the content. Depending on their selection, different content is displayed across the whole site, other than a contact and about page. The tone of the language changes depending on whether the visitor is a student or teacher and the materials available on each page also change depending on the learning level, however in all cases, the structure of the site is identical. Currently I'm using a cookie to store the visitor's selections and render different content appropriately, so I have a single set of URLs which display different content depending on the cookie, with one of the permutations as default. I appreciate this is far from ideal, but what is the better option? Would I be better using a distinguishing segment for each selection, for example: http://example.com/teacher/lv3/resources/activities http://example.com/teacher/lv4/resources/activities http://example.com/student/lv4/resources/activities etc. What is the most sensible way to handle this situation?

• Force '^C' to be printed when editing current prompt, then aborting it

  - by Stefan Lasiewski

  This is the opposite of Prevent “^C” from being printed when aborting editing current prompt. I'm using Bash. When I'm editing the commandline in Bash, and I hit Control-C to abort the commandline, the '^C' character does not display. I would like to see this character. I tried commands like stty -ctlecho and stty ctlecho (which I borrowed from the other question), but this didn't work for me. This behavior seems to be true with my environment on Ubuntu, CentOS and MacOSX.

• Blank screen during boot after clean Ubuntu 11.10 install (Intel N10 graphics)

  - by Coen

  After a clean install of Ubuntu 11.10 on my Asus eee PC 1005p, Ubuntu seems to boot correctly, except for initialization of the LCD screen. What I observe: I choose Ubuntu 11.10 in the GRUB 2 menu A blank screen with a blinking cursor in the top left of the screen, for 15-20 seconds. The ubuntu logo with 5 red dots in the center of the screen, for 1 second. The LCD screen is entirely blank The startup sound plays (Ubuntu is configured to auto-login) Still, the LCD screen is entirely blank. When I press Fn-F8 (the switch between LCD screen and external VGA), the LCD screen shows my desktop correctly and everything seems to work fine. Except for the adjust contrast buttons (Fn-F5 and Fn-F6), these seem to cycle through random brightness modes. Something like: 0% - 50% - 20% - 0% - 20% - 0% Any ideas what's causing this or how to solve this? coen@elpicu:~$ lspci -v 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.

• Can a custom DPI setting be applied to Remote Desktop sessions?

  - by sejong

  Can a custom DPI setting be applied to Remote Desktop sessions? When you try to change the DPI from a Remote Desktop session, you get a message that display settings can't be changed from a remote session. That made me think that changing DPI from a console setting would work. It did, sort of. If I connected via Remote Desktop to an existing console session with a custom DPI setting, that setting would be applied to the Remote Desktop session. However, if I logged off that session, the custom DPI would not be applied to subsequent Remote Desktop sessions even though it was maintained for subsequent console sessions. It looks like the registry value HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics\AppliedDPI (and perhaps other values) is overwritten at logon, but I haven't been able figure out how to prevent it.
