• Ubuntu 12.04 resolution stuck on 640x480

  - by user212483

  I am new to Ubuntu and I was trying to get my HDMI enabled TV to work with my Ubuntu 12.04 computer and I installed a Nvidia driver using the "additional drivers" program. After that didn't work, I started playing around with the dual booted windows 7 on my computer. Now, I've never used that windows since I installed it so I was stripped down to bare minimum so I tried to adjust the resolution(as it was on lowest resolution) and tried to connect the HDMI, which didn't work. After that I came back to my Ubuntu installation only to find out that it is now stuck on 640x480 resolution. I tried to remove the driver that I installed again using the "additional drivers" program but that didn't help at all. The error that showed up was - Could not apply the stored configuration for monitors none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Any help would be appreciated as this is very annoying. Thanks

• Never before had a problem with Ubuntu desktop graphical display; Trying to use nvidia GT630

  - by focaccio

  I've been using ubuntu since 9.04 and never had a problem with Ubuntu brining up the desktop graphical user interface. However I am currently not able to see anything graphical past the install screens. I have an Intel DP55KG motherboard and just installed an nvidia gt630 graphics card (zotac), since the old graphics card failed. I can install the server and see text. So I do a apt-get install ubuntu-desktop...or apt-get install kubuntu-desktop...or apt-get install xubuntu desktop, but after the reboot there is no display...its like something is hung up. I tried using the Live quantal dvd and I do see the graphical prompt to try without installing, but after that the screen goes blank. I've tried two monitors and the same thing happens. There is a faint "glow" on the screen and I do not get a "no input signal" from the monitor, so something is happening. I can install an old OEM of XP so I know the video card and motherboard are at least semi functional. Any help is appreciated. Thanks, Greg

• Nvidia driver installation results in resolution change to 800x600 with Xubuntu 10.04 (can't change)

  - by Jim Michael

  I have a 2.8 P4 and a Nvidia FX 5500 AGP graphics card. I've installed Xubuntu 10.04. It is WAY too laggy with the default o/s driver. Installing the Nvidia 173 driver, modaliases and nvidia-settings packages via synaptic package manager results in the following error message: An error occurred, please run Package Manager from the right click menu or apt-get in a terminal to see what is wrong. Error: Opening the cache (E::read, still have 11898251 to read but none left, E: The package lists or status file could not be parsed or opened.) This usually means that your installed packages have unmet dependencies. When restarting the PC the resolution drops to 800x600 (from the monitors native 1440x900). Nvidia settings cannot be changed either from the Xfce menu or Nvidia Xserver. Nvidia Xsever gives the following error message: You do not appear to be using the Nvidia X driver. Please edit your x configuration file (just run 'nvidiaxconfig' as root ) and restart X server. Also, I can't find anything in any directory called xorg.

• Multi-screen and Nvidia GT220

  - by Bohors

  Excuse me first for my broken English I have 3 monitors on two Nvidia GT220. Unity 2D works fine after using the proprietary drivers. But no way to use compiz effects.

• Will the Driver Support for Intel HD Graphics be Improved in 12.10?

  - by Hiranya

  I recently installed Ubuntu 12.04 on a HP Pavilion dv4 laptop. This is a core i7 machine with Intel HD graphics and also a separate nVidia VGA card. I had a lot of issues getting Ubuntu 12.04 working on this system. First there were issues booting up the live CD for installation. I worked around that by using the 'nomodeset' option. Then I continued to have similar issues after installation has completed. So I had to permanently add the nomodeset option to my GRUB boot configuration. At the moment I have a working installation but there are many issues: Ubuntu GUI is a bit flaky at times. The mouse pointer goes on and off when hovering over certain icons. Certain things doesn't get rendered properly on the screen. I can't access any of the tty consoles. Hitting Ctrl+Alt+F[1-6] gives me a blank screen. And once that happens I can't even come back to the UI by hitting Ctrl+Alt+F7. I've realized that tty consoles are actually working. I just can't see the text. If I enter a command like 'sudo reboot' into the empty screen the machine reboots. Can't get external displays (monitors, projectors etc) working. But I think this is probably because the VGA out is wired to the nVidia card which is not being used by Linux. colord program crashes every now and then triggering a popup message. So my main question is, will the support for Intel HD graphics be improved in the next release? Or will I have to keep using the nomodeset option in the new release too? Also I appreciate if anybody can shed some light on any of the issues listed above. Thanks in advance.

• nVidia 9800 GTX+ X11 fails to initialize. no unity or lightdm

  - by rlemon

  I have just upgraded my work pc to 12.04 (not upgrade, fresh install), installing updates during the install, and after everything has loaded (with no errors) and I restart I get brought to console 1 tty login. Console 7 looks like this: IIRC I did not have to finagle with my drivers on 11.10 to get this card working. If this is in fact a driver bug I will remove this post and submit the bug but i'm not 100% confident that it is. I attempted to run unity --reset and got this: Lastly I tried $ sudo apt-get install nvidia-current which tells me nvidia-current is already the newest version. so I ran $ sudo dpkg-reconfigure nvidia-current which says /usr/sbin/dpkg-reconfigure: nvidia-current is broken or not fully installed. Anything I can try from here would be awesome. Currently the only way to get the system up and running was to shut down, plug one of my monitors into the onboard video, enable the onboard video card from the BIOS, then boot back up (and on my single monitor everything is fine). update So I have been able to boot fresh with the ext card plugged in as long as I don't take the updates with the install. past this if I only install the nvidia drivers (nvidia-current or nvidia-current-updates) from the main server (or canadian) I then get the problems.. My proposal; which I don't know where to look for: Can I try installing the previous version of this driver? In the past, on another machine I had issues with my NIC driver being funky... downgraded to the previous driver and bam everything was merry and well.

• Is it possible to keep only one Database for both web and desktop applications?

  - by B4NZ41

  I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

• Do i need to restore iptable rules everytime on boot?

  - by capdragon

  Every time i reboot i loose the iptables rules that took me sooo long to enter. I know i can save them and restore them on boot but is there anyway to save them forever? Do i really need to restore them on boot every time? Seriously? The problem is I have a HUGE list of IPs in which i use a while loop to load them in. This can take upwards of 10 minutes. This is my home FTP server. It's a small vm with 1gb ram and very little processing power. There are so many IPs because I've pretty much given up on the Asian continent. I don't need them to be hitting up my ftp server everyday with brute force. I also block gov. monitors, trackers and spammers. This is the while loop i use to load in the list. grep INPUT block.list | while read LISTA; do sudo iptables -A $LISTA; done

• Can't install GTX 680 drivers on 12.04

  - by user68945

  I recently installed Ubuntu 12.04 on my desktop. I have three monitors, and after installing, ubuntu only detected one at 1080p. I downloaded the driver from the nvidia website, but when I stop lightdm and try to run the driver, it gives me an error message: ERROR: Unable to find the kernel source tree for the currently running kernel. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option. I tried instead to install the driver via the terminal, with the X ppa. The installation seemed to work, but when I rebooted, my display was at 640x480 resolution, with no other options for resolution. The NVIDIA X Server settings program is there now, but when I run it, it simply tells me that I don't seem to be using their driver, and that I should run nvidia-xconfig as root. Doing so doesn't help, I simply get the same issue again. I checked the file at /etc/X11/xorg.conf, and it's an NVIDIA file (has nvidia in the header). Does anyone know something else I can try? EDIT: Forgot to mention, I tried installing drivers via the "Additional Drivers" GUI utility, there were two options, one of them marked "(post-release updates)". I tried both of them, in both cases it tried to download and install for a while, then said that there was an error, and that a description could be found at /var/log/jockey.log. Both logs were over 700 lines

• Visually recognise active window

  - by mcaleaa

  Ubuntu 13.04 I work with two monitors, usually with lots of different windows open. I don't like to use the mouse, so swap between applications using alt-tab usually. The problem comes when I want to type something into an application. I need the active application to immediately obvious, usually so that I can tell which monitor to look at next. With default ubuntu (with appearance = ambiance), the only real visual indication of a window being active is that the header bar of the application is in a lighter font color. This is too subtle for me, so I find myself alt-tabbing and moving my mouse too much when switching applications, then clicking around with the mouse to give a particular window the focus. I want my switching to be more accurate, and for that I think I need better feedback on what window has the focus. This needs to be more obvious than it is now. I looked at the high contrast appearance, and it helps somewhat, but the inconsistency in the icon sets is far too distracting. I think what I need is a something like a bright border right around the window, or something like that, to make the active window really stand out. Or, maybe to have the non-active windows fade to the background a bit. I would appreciate tips on how others overcome this problem, to make the active window stand out visually from the other windows. Thank you!

• Ubuntu 11.10 Random reboots how to find root cause?

  - by Indigo42

  All, This issue started with 11.04, I upgraded to 11.10 this week in hopes it would correct it, but after a few days it happened again.. A few times a day, randomly, my monitors will go black and the machine will come back in the post screen and boot up again. Sometimes it boots up properly, sometimes it boots to disk scan (I understand why...the machine just died with a bunch of stuff open) and sometimes it takes several cycles of this to come up. I connected to the system with my laptop and tailed dmesg, syslog, kern.log, and Xorg.0.log. I also ran a cat /proc/kmesg. Nothing is showing up in any of these log files when it happens..it's just like someone has pulled the plug. I just got through running 4 hours of the memory test with no errors. I have a AMD Phenom 9850 Quad-Core Processor and Nvida 9500GT graphics card. This system has been stable for like 4 years. I'm thinking it might be a hardware problem, but how do I find out? Thanks,

• Precise exposition of an image for set number of frames (Vsync?)

  - by Istrebitel

  I need to make a simple enough program in C#, but it seems to be impossible via usual WinForms means. I need to show something (a string of text, an image) on the screen for very small time interval. Since typical monitors are 60Hz, this interval would be 1 or 2 frames (16,6 or 33,3 ms). I tried doing this with usual WinForms, and it is not possible because, apparently, there is no way to know how many frames were output to the monitor since some point in time. I can only draw on the controls, and monitor output is totally independant. So even if I run the timer, say, for 17 ms, between showing and hiding the image, it still sometimes manages not to draw a single frame of my image on the screen (even though theoretically it should, because 17ms 16,6ms). Moreover, even 20ms seems to slow (even though i should be more than enough). I did some game development as a hobby in the past (Delphi X, XNA) and I know that you usually draw the whole screen by yourself, each frame. Also, I know that there is an option called Vsync in most modern games, that allows you to synchronize your framerate to your monitor's frame rate. So, is it possible? I mean, to actually know how many frames were sent to the monitor with w/e I want to show?

• QT4 - MDI model or Dock Windows?

  - by umanga

  Greetings, In the QT application we develop we need to display several 'Viewer windows'(to display data in XY plane ,YX plane,XZ plane and in 3D). We were hoping to use MDI application model ,but later client asked for a requirement to drag and view 'Viewer windows' in multiple desktops.(using multiple monitors). This can not be done using MDI window model ,because we cannot move MDI window outside the Main Application Window. Only possible way is to use Dock windows because they can be undocked from Main Application Window and move into other desktops, but Dock windows primary used for tool-palettes or utility windows. (http://doc.qt.nokia.com/4.6/qdockwidget.html#details) Is it a good practice to use Dock window for our requirement? thanks in advance.

• How do I aggregate results from an Adjacency list using PHP's SPL

  - by Stephen J. Fuhry

  I've tried using nested sets, and they become very difficult to maintain when dealing with multiple trees and lots of other complications.. I'd like to give PHP's SPL library a stab at this (btw, we are PHP 5.3, MySQL 5.1). Given two datasets: The Groups: +-------+--------+---------------------+---------------+ | id | parent | Category Name | child_key | +-------+--------+---------------------+---------------+ | 11133 | 7707 | Really Cool Products| 47054 | | 7709 | 7708 | 24" Monitors | 57910 | | 7713 | 7710 | Hot Tubs | 35585 | | 7716 | 7710 | Hot Dogs | 00395 | | 11133 | 7707 | Really Cool Products| 66647 | | 7715 | 7710 | Suction Cups | 08396 | +-------+--------+---------------------+---------------+ The Items +------------+------------+-----------+----------+---------+ | child_key | totalprice | totalcost | totalqty | onorder | (jan, feb, mar..) +------------+------------+-----------+----------+---------+ | 24171 | 10.50 | 20.10 | 200 | 100 | | 35685 | 10.50 | 20.10 | 200 | 100 | | 76505 | 10.50 | 20.10 | 200 | 100 | | 04365 | 10.50 | 20.10 | 200 | 100 | | 01975 | 10.50 | 20.10 | 200 | 100 | | 12150 | 10.50 | 20.10 | 200 | 100 | | 40060 | 10.50 | 20.10 | 200 | 100 | | 08396 | 10.50 | 20.10 | 200 | 100 | +------------+------------+-----------+----------+---------+ The figures are actually much more complicated than this (I am actually aggregating a variable amount of months or years over the past 15yrs, so there may need to be 20 columns of aggregated results). I have been trying to figure out RecursiveIterator and IteratorAggregate, but I am having a difficult time finding real world examples that are generic enough to really wrap my head around these classes. Can someone give me a head start?

• Xrandr errors. BadName (named color or font does not exist)

  Hi, I've been looking and googling a lot, but I didn't find a solution to this problem. I was successfully using xrandr to extend my desktop in my work place with this little "script". #!/bin/sh xrandr --newmode 1920x1080 220.64 1920 2056 2264 2608 1080 1081 1084 1128 -HSync +Vsync xrandr --addmode VGA 1920x1080 xrandr --output VGA --mode 1920x1080 Everything was going well till one day that magically stop working. When I try to use it. I just get this message. X Error of failed request: BadName (named color or font does not exist) The laptop display resizes in a strange way, but nothing happens with the extended monitor. I've restored gnome desktop default config. I changed the font config, I tried with other layouts and monitors, but always occur the same. So any Idea will be welcomed. My best regards.

• Find new messages added to an imap mailbox since I last checked with python libimap2?

  - by vy32

  I am trying to write a program that monitors an IMAP mailbox and automatically copies every new incoming message into an "Archive" folder. I'm using imaplib2 which implements the IDLE command. Here's my basic program: M = imaplib2.IMAP4("mail.me.com") M.login(username,password) lst = M.list() assert lst[0]=='OK' for mbx in lst[1]: print "Mailboxes:",mbx def process(m): print "m=",m res = M.recent() print res M.select('INBOX') M.examine(mailbox='INBOX',callback=process) while True: print "Calling idle..." M.idle() print "back from idle" M.close() M.logout() It prints the mailboxes properly and runs process() when the first change happens to the mailbox. But the response from recent() doesn't make sense to me, and after the first message I never get any other notifications. Anyone know how to do this?

• How to monitor screen updates?

  I am trying to write a program that monitors when the screen has been redrawn. Meaning if any part of any window is redrawn, then the program is notified. As far as I understand I should use a journal record hook like at http://www.vbaccelerator.com/home/vb/code/libraries/Hooks/Journal_Record_Hooks/article.asp However, I do not understand which MSG type would get me the WM_PAINT events (WH_CALLWNDPROC and WH_CALLWNDPROCRET do not seem to do the job). I'm not even sure that WM_PAINT is what I'm looking for... Basically, if I knew when the DC associated with GetDesktopWindow() has changed then my problem would be solved. Question is: How do you monitor screen updates?

• CruiseControl / NANT <copy> Task

  - by Striker

  We have a website with all the media (css/images) stored in a media folder. The media folder and it's 95 subdirectories contain about 400 total files. We have a Cruiscontrol project that monitors just the media directory for changes and when triggered copies those files to our integration server. Unfortunately, our integration server is at a remote location and so even when copying 2-3 files the NANT task is taking 4+ minutes. I believe the combination of the sheer number or directories/files and our network latency is causing the NANT task to run slow. I believe it is comparing the modified dates of both the local and remote copy of every file. I really want to speed this up and my initial thought was instead of trying to copy the whole media folder, can I get the list of file modifications from CruiseControl and specifically copy those files instead, saving the NANT task the work of having to compare them all for changes. Is there a way to do what I am asking or is there a better way to accomplish the same performance gains?

• Interface Builder and Xcode integration not working

  - by Martin Cote

  After having installed the iPhone SDK 3.1.2, Interface Builder is not in sync with Xcode anymore. The light indicator at the bottom of the XIB window is grey. IB doesn't see any files from the Xcode project. Xcode is always open when I start IB. I tried rebooting. No luck. I tried removing the preferences files for Xcode/IB. No luck. I tried reinstalling Xcode/IB. Still no luck. This page explains how IB monitors the changes in Xcode. While it was an interesting read, it didn't provide any help about how to investigate my problem. Any help would be appreciated. EDIT Here's additional information. I enabled the debug logs for launchd, and I noticed the following line that appears every time Interface Builder is started: [0x0-0x1b01b].com.apple.InterfaceBuilder3[315]: Couldn't open shared capabilities memory GSCapabilities (No such file or directory) This really seems to be related to my issue.

• How would I best address this object type heirachy? Some kind of enum heirarchy?

  - by FerretallicA

  I'm curious as to any solutions out there for addressing object heirarchies in an ORM approach (in this instance, using Entity Framework 4). I'm working through some docs on EF4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

• Right way to create [self]respawning app in python

  - by grapescan

  I am using jabber bot written in python to log some MUC talks. Sometimes it drops on some network or XMPP problems. In this case I have to start it again by myself. The goal is to make it "self-respawning". I have some variants about how to do it. Bot is one process. Another process monitors its activity and starts it if bot died. Main process spawns bot subprocess and controls it. Also I think daemonizing bot process is useful here. Platform is Linux, as you could guess. What is the right way to solve this problem?
