  • White Screen, No Errors.

    - by GruffTech
    So.. Interesting problem for you guys, As I'm completely lost as to what to do, or where to take the next step. Server & Application Environment. CentOS release 5.3 (Final) Apache 2.2.3-22 EnableSendfile off EnableMMAP off ErrorLog logs/error_log LogLevel debug PHP-5.2.6-2 error_reporting = E_ALL display_errors = on log_errors = on max_execution_time=300 max_input_time=60 memory_limit=512mb Kohana 2.3 PHP Environment. HAProxy 1.3.15.6-2 MemCacheD 1.2.6-1 Our application is split between 3 web servers, mounting a NFS Storage server, and sticky load balancing between the 3 web servers. The application seemingly runs great, but every so often, instead of loading, the application just shows a pure white page. Not a 404 Error, or a 500 Server Error, a clean white page. And it returns instantly, so its not a execution time error. Nothing in the Error log, or Server-Error Log, Proxy log shows standard proxied connection, Just the standard 200-Status in Access log, with 256 bytes transferred. To me, this leads to tell me that the application itself is having a problem. A rare, unexplainable, seemingly random, problem that causes what we've now called the "White Screen of Death." Our developers all say that since there is nothing going to our error logs, that it must be a server problem. But I say the same thing, There's nothing going to ANY of our logs (relevent to this anyway), and we're not having httpd children crash from what i can tell. Any ideas on how i can increase my logs, or somehow prove that its not a bug in PHP, Apache, CentOS, ect? Or if it is somehow a bug, identify it?

  • using a second computer as a mere screen/monitor in X (VNC?)

    - by lara michaels
    Hello My goal is to use three monitors with my Linux system. It is a laptop, so adding another video card is not the easiest solution. (I have investigated a number of such options: getting a docking station with a PCI slot, USB/Cardbus vga adapters, etc, and for the time being don't want to go that way.) I am wondering if using an older desktop+screen I have lying around as the third "monitor" might be the easiest solution, if only there is a way to get it to work as a seamless, integrated desktop. I was wondering if I can use VNC or perhaps X itself (?) to achieve the following: computer A is my main computer; it has all my files, etc. computer B is used just to display on an additional screen keyboard+mouse are connected to computer A use VNC or X to connect the two so that computer B shows a X screen that is just as if it was a third physical screen connected to computer A. I don't know if the last point is clear, but what I mean is that I would like to be able to: be able to have my window manager assign/move around virtual desktops on all three screens move windows back and forth between the screens attached to computer A and the screen of computer B be able to copy something in an app being shown on a screen of computer A and paste it into an app being shown on the screen attached to computer B access the filesystem on my main computer (A) when using applications that are being shown on the screen attached to computer B Basically, I would like X to treat computer B just like it was nothing but a third physical screen... Is this doable? : ) ~lara

  • MacBook Air i5 4 GB RAM shows screen tearing when scrolling in browsers

    - by Sandro Dzneladze
    I see screen tearing pretty often while scrolling webpages up and down, and it has been like this from day 1. But now I purchased an external monitor which is huge (23 inches compared to the Mac's 11), and the effect is more visible. It is driving me nuts and giving me headaches. I wonder if you see the same. I was reading a lot about this problem, and it seems to be present on MacBook Pros as well? Can someone confirm I'm not alone? In other words: I'm deciding weather to go through warranty repair, or if it makes no sense if all of theme exhibit same behavior. It is shame to see this beautiful machine with an insane price tag to be lagging when browsing web, when the processor is just sitting there idle at 4-12%! This is an example I found on Wikipedia that more or less describes what happens when I scroll up down. The effect is not so pronounced and clears when I stop scrolling, but it is sure annoying the hell out of me. Firefox is tearing like hell, Chrome less, Safari exhibits jagged scrolling but less tearing compared to Chrome and Firefox. With synthetic benchmarks I don't see any problems with hardware. But this is not particularly revealing.

  • Applications randomly alt-tab? (especially full screen games)

    - by Henry Scotts
    I'm not sure when this began, how it happens, or why it happens, but it is quite bothersome and apparently random. Just randomly throughout the day my computer will just go to the desktop. I could be in a full screen game and it will just immediately alt tab and present the desktop. Or I could be watching a movie and this happens. Sometimes it happens once every three hours and other times (just today actually) it did it twice in the span of 30 seconds. I am positive I am not pressing a hotkey because I launched a game, sat idle, and noticed it alt tab while cleaning up around my room after about 20 minutes. Sometimes it goes days without this happening. Specs: Windows 7 Ultimate 64 Bit, 10 gigs of RAM, GeForce GTX 260, Intel Xeon CPU. I also have basically nothing running when it happens other than the game and FireFox. My FireFox add-ons: Adblock Plus, Download Statusbar, Firebug, FirePHP, lazarus form recovery, tree-style-tabs, yslow. I doubt FireFox is causing the issue but I figured I'd include it anyway because it is the only application I have running when it happens. As for user processes I have running: VCDDaemon (context menu for virtual clone drive), razerhid (mouse), OSD, taskhost, dmw (desktop window manager), anyfullscreengame, audiorepeater, netsession_win, explorer, razerofa, tsvncache, firefox, plugin-container, and EKIJ5000MUI (printer). Whew. Okay. That was a lot of information. If someone could diagnose this I would be most grateful for this has been around with me for years.. Thanks for reading! PS: I doubt it's a virus because I never download illegal software and pretty much only browse Reddit and Stackexchange and play games. If it was a virus it would be a pretty lame one.. Hah..

  • How to get rid of Windows XP Pro Blue pop up screen

    - by LISA
    Windows XP user-home edition 36 bit. One day I woke to see a blue pop up screen from Microsoft Windows XP Pro. I have not installed anything new myself. The 'add on' pop up always comes on when I open up mozilla to surf the net. I always just close it out to not install anything. I then woke to have colored tabs, the new download status bar at the bottom and this pop up window that asks me to retype two words spaced, a timer of two minutes starts and states if no word put in system will shut off. I have let it run down more than a few times and it does not shut down. No other options to choose from. If I misspell with a lot of letters it tells me I did so, but if I can't read a few letters I guess at it although it is not and it lets me resume what I am doing. This window pops up every single minute no matter what I am doing. Please help, I'm really annoyed with this. I have searched the net all over and don't quit know what to look for anymore

  • Windows 7 boots to black screen with blinking cursor

    - by murgatroid99
    I have an Alienware M17x that dual boots into Ubuntu 11.04 and Windows 7 Home Premium. Currently, the computer starts at the GRUB loader and will boot into Ubuntu, but if I try to boot into Windows, I immediately get a black screen with a blinking cursor in the upper left corner. The output of fdisk -l is Device Boot Start End Blocks Id System /dev/dm-0p1 1 5 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/dm-0p2 6 1918 15360000 7 HPFS/NTFS Partition 2 does not start on physical sector boundary. /dev/dm-0p3 * 1918 64772 504878877+ 7 HPFS/NTFS Partition 3 does not start on physical sector boundary. /dev/dm-0p4 64772 77827 104858625 5 Extended Partition 4 does not start on physical sector boundary. /dev/dm-0p5 64772 67204 19531008 83 Linux /dev/dm-0p6 67204 74498 58593536 83 Linux /dev/dm-0p7 74498 77577 24731648 83 Linux /dev/dm-0p8 77578 77827 2000128 82 Linux swap / Solaris I have used the Windows rescue CD, and run the automatic error fixer until it finds no errors. I have run chkdsk /R on both the main Windows 7 (/dev/dm-0p3) partition and the recovery partition (/dev/dm-0p2). I set the main Windows 7 partition to be active. I also tried running in the recovery console the commands bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd None of these helped and the last set of commands deletes grub, which I then have to reinstall from Ubuntu. I think the last thing I did in windows before this started was install the newest ATI driver for my video card. This would suggest using system restore, and I actually had a restore point earlier (after the problem started), but after whatever I did that restore point does not appear in the list on the recovery disk any more, so I cannot do a system restore. Is there anything else I can try to make Windows boot properly again? Edit: Running the suggested commands bootsect /nt60 c: bcdboot c:\windows /s c: was also ineffective.

  • Display stretches 4:3 ratios; Adds scrolling to other ratios

    - by Matt
    I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks EDIT: After playing around more, I discovered that the "scrolling" behavior is only present for aspect ratios that are not 4:3. For 4:3 ratios, it just stretches out to fit the wide screen. My monitor's native ratio is 16:9 .. what could be causing it to think it needs to scroll?

  • Light Blue Monitor Screen

    - by SixfootJames
    I have seen this before with an older monitor that over time, the monitor colours change to a light blue haze. This has started happening with an older monitor of mine now (A GigaByte Monitor) and although none of the pins are bent and it's a brand new machine, there is no reason, other than aging that it should show the light blue screen. Perhaps it is just time for a new monitor, but if there is a way of saving it still. I would appreciate the insight. Perhaps there is something I have not tried, perhaps it has something to do with the new machine instead of the monitor? I had the monitor plugged into two other machines over the weekend and didn't have this problem. So I am not quite sure what to make of it. Many thanks! EDIT: I must also add that when I plugged the monitor into the older machines, I had the VGA converter attached to the end of the newer DVI output. Which, when plugged into the newer PC, I don't need of course.

  • Utilities for finding x/y screen coordinates

    - by slothbear
    I have an application that needs the user to enter the x and y location of a couple of items on the screen. [Yes, this is crap and I'll replace it, but for now...] On Mac OS X, I'm using Snapz Pro X. When I choose to take a snap of a selection, the interface displays the mouse cursor location. This is OK for my personal use, but I can't ask users to buy a $69 program for this function. I thought I had a solution with the built-in program "Grab", but it reports the coordinates from the bottom left, and I need it from the top left. I don't have access to Windows; not sure what to use there. I've not even been able to come up with good search terms since mouse and coordinates and x/y are so common. Ideas are welcome there. Extra credit: same x/y finder for Linux. A Java program would be OK too, since the main application is in Java.

  • I have a perl script that is supposed to run indefinitely. It's being killed... how do I determine who or what kills it?

    - by John O
    I run the perl script in screen (I can log in and check debug output). Nothing in the logic of the script should be capable of killing it quite this dead. I'm one of only two people with access to the server, and the other guy swears that it isn't him (and we both have quite a bit of money riding on it continuing to run without a hitch). I have no reason to believe that some hacker has managed to get a shell or anything like that. I have very little reason to suspect the admins of the host operation (bandwidth/cpu-wise, this script is pretty lightweight). Screen continues to run, but at the end of the output of the perl script I see "Killed" and it has dropped back to a prompt. How do I go about testing what is whacking the damn thing? I've checked crontab, nothing in there that would kill random/non-random processes. Nothing in any of the log files gives any hint. It will run from 2 to 8 hours, it would seem (and on my mac at home, it will run well over 24 hours without a problem). The server is running Ubuntu version something or other, I can look that up if it matters.

  • Persistent PuTTY sessions for multiple windows

    - by Tgr
    I'm working in various Linux environments through PuTTY connections which break from time to time. I'm looking for a solution to make the PuTTY windows persist (e.g. if I was editing a file, then after reconnecting I should be in the same editor with the same file open at the same place), with the following requirements: it shouldn't require any manual setup at the beginning of the session or after reconnection (I don't want to type in screen or anything like that) I have several windows open to the same machine with the same user, which tend to disconnect at the same time the number/role of windows is not constant (it's not like I have an mc window, a mysql window and a "script runner" window; sometimes I use one window for search or for SVN commands, other times I need several at the same time) sometimes I need to change the properties of the windows for a task (large window for grepping/editing, small windows because I need to see two of them at the same time, red background because I am modifying the live database in MySQL etc), so I need to get the same console back in the same window after a reconnect Is there a way to achieve this? I suppose I should use screen or something equivalent, but how does it know which window I am reconnecting from? Is there some way to pass a unique window identifier to the shell from PuTTY?

  • Laptop freezing every few seconds, including screen + sound

    - by zenstealth
    Just a few days ago, my Windows 7 HP dv4170us (1.76Ghz CPU, 1GB Ram) laptop started to freeze every other second where everything on screen and and sound (such as a song playing in iTunes) would just freeze until I bash it violently (without actually breaking the laptop) or wait for a couple of more seconds. I think it started one night when I noticed that a USB mouse of mine stopped working, and it displayed random "Device was not recognized" errors. I just unplugged the mouse and ignored it. Skip forward to the next day, is started freezing, and as of today I can't get my computer to not keep freezing. I tried to backup my files onto an external hdd, but it almost corrupted the drive. I ran 4 complete virus scans using MSSE and MalwareBytes (both quick and full scans), and they all came up clean. In the Task manager, the CPU usage is on a constant max, and so is the RAM (if I have just a few apps running, I only have like 30Mb of free RAM left). Also, on the outside of my laptop, right above where the CPU is located, it's very, very hot. I suspect that something is wrong internally within inside of the computer, but I'm not sure. It also does the same thing when booted into Ubuntu.Does anyone know what could be wrong with it?

  • Windows 7 pc freezes for an indeterminate amount of time after unlocking

    - by pikes
    Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

  • Should I update the kernel on a Linux machine?

    - by Legate
    As I understand it, updating to a new kernel (with the normal linux-image... package, not by rolling my own) requires a server restart. However, one of our servers (Ubuntu 10.04) is running several extensive screen sessions. Restarting kills those which is always a major hassle to their owners (mostly because of lost session histories). What should I do? I see several possibilites: Not doing anything, that is update only non-kernel packages (perhaps use apt-pinning?) Update the kernel, but not restart. (Is that smart? I seem to remember there might be some problems with loading kernel modules.) Updating the kernel and restarting. Is there perhaps some way to preserve the screen sessions? I guess it ultimately boils down to this question: How important is it to update the kernel? I posted this question here instead of askubuntu.com as I think this is not an Ubuntu-specific issue though this server is running Ubuntu.

  • Remote Desktop svchost (networkservice) & lsa.exe high cpu usage, hangs on welcome screen

    - by Rohan1
    We have deployed an RDS Farm with 12 virtual RDS servers using Hyper V. Currently some users are not able to log on. After passing credentials to the connection broker, the session hangs on the "Welcome" screen. Using resource monitor we've seen that svchost (with the "networkservice" service) has a CPU usage of 50%, when viewing the wait chain on the process it displays that it's waiting for a lsa.exe to finish. We can't kill any of the users processes, even when trying with taskkill /f. Suspending lsa.exe did work but didn't have any effect. The networkservice also couldn't be restarted. Also, if this happens, the current users logged on to the RDS server can't be displayed. Task manager crashes when viewing the users, RDS service manager crashes when viewing the users (even remotely) and the cmd command "query session" doesn't work. No antivirus is installed on the RDS server. The only thing we can do is rebooting the server, which is not an option because of the fact that other users are in active sessions. Does anyone have ANY idea what's going on? We didn't encounter this in our pre-production setup.

  • android incoming call screen

    - by shaimagz
    I would like to add details to the incoming call screen on android. lets say I have a string 'x', so I want 'x' to show up on the incoming call screen under the name of the person who is currently calling. I know this is possible because of this apps: CallerId, Vringo I'm pretty new to this area, so I need to know what is the process to achieve that, for example: get the event of incoming call, go to the incoming call interface and so on. Thanks!

  • CSS difficulty horizontally displaying / repeating left and right wrapper images to ends of screen

The left and right repeaters are background images (approxamately 350px wide) that I would like to show part of, or even repeat if the screen (visible area of screen shown in red) becomes wide enough. Any help or suggestions would be greatly appreciated! Thanks, John

  • Having a Backgroundworker refresh splash screen

    - by Jiri
    Hi, Would it be theoretically possible to make BackgroundWorker in a class to periodically refresh existing splash screen form, or is that impossible? (I know that it's probably bad design, but currently I do not see any better way.) Please keep in mind that: I do not want the background worker to do the loading as it would be terribly hard to implement. I can't use the inbuilt splash screen support I'm aware of DoEvents alternative but I do not want to go this path, it would very hard to implement as well, and not reliable.

  • Anchor Window to Screen Edges in C#/WPF

    - by Kirk
    I've decided to teach myself C# by writing a music player in Visual Studio 2010. I went with WPF because from what I hear it sounds like it will be a good base to skin from. I want to program my window with the behavior where if the window comes to the edge of a screen (within 10px or so) it will snap to the screen edge. What's the best way to go about this?
