  • how do I fix ati driver issue

    - by Michael
    I have little knowledge about ubuntu, but I am learning. Recently, my ubuntu 12.04 required that I update. I noticed that it was updating xorg and other things, after the update I was asked to reboot. I did. now when I start that computer up, it cannot detect any display and refuses to boot from usb. I have no idea how to recover my computer. It simply starts in what is akin to the terminal program and ask for my username and password. After that, I can enter commands. The problem may be because I manually installed drivers by copy pasting from some instructional that I now have no idea where they are, but what it amounts to is that I "built" the drivers. They were working GREAT until this update. I did this because otherwise I was unable to have sound through my hdmi. After I hand built the drivers, they worked great. After this update Ka-blam! nothing... Also, I had okay-ed lots of update sources (though all of them [xorg and such] were the stable versions, not the unstable update sources) Please help and thank you in advance. (if this is posted incorrectly or misplace, please let me know what to do)

  • Why doesn't my Nvidia driver support 1280*1024?

    - by Alvar
    EDIT: I think the problem is in the NVIDIA x server, that doesn't support an RGB screen from 1990. The screen was the best of them all when it was released. This a strange thing! In windows the EDID must work because 1280*1024 is used as max resolution, but in ubuntu those stuff aren't being received, so how do I tell ubuntu/nivida to find those EDID stuff? Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't. The screens model name is IntelliColor Display/20 and the name of the company is "radius".recived Well, twin view is working but the only maximum resolution is 1024*768. I'm using nividas x server program. If I force it to use 1280*1024 it all crashes and I have to force a reboot. alvar@alvars-laptop:~$ disper -l display DFP-0: HSD121PHW1 resolutions: 320x175, 320x200, 360x200, 320x240, 400x300, 416x312, 512x384, 640x350, 576x432, 640x400, 680x384, 720x400, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 832x624, 1024x768, 1366x768 display CRT-0: CRT-0 resolutions: 320x240, 400x300, 512x384, 680x384, 640x480, 800x600, 1024x768, 1152x864, 1360x768

  • display driver problem

    - by Robert
    I just recently installed Ubuntu 12.10 on my laptop and am keeping windows 7 as a back up for when I get stuck like now..... After I installed Ubuntu I got on line and was reading about some of the things to do after Installing for the first time. One of them was looking for additional drivers witch I did and found two display drivers. Both drivers were from Ubuntu. However after install and a reboot I can't see any of my menu bars.....no app bar on the side.....no bar at the top of the display...nothing. I did have a file on the desktop that I was able to open. And I just learned that ctrl+alt+T gets me a form of command prompt. this worked but I don't know how to use it. How do I get my menu bars back?? is there a way to uninstall the drivers? I am really new to Ubuntu and like it so far but am having problems getting over the learning curve.

  • Ubuntu 12.04 terminal only after nvidia driver upgrade

    - by user1613361
    I recently installed Ubuntu 12.04 (after getting tired of Windows). Installation went fine. I had one problem when I got in suspend mode and then resumed my screen was scrambled. After some googling founds some tips to upgrade my nvidia drivers. I did this, and rebooted but only a terminal windows appears now instead of a graphical desktop. Tried to fix it by several reboots, and removing xorg.conf, but still no luck. Any advice how to fix it and get my desktop back ?

  • Incrementing ticket numbers each time I print

    - by Danny
    I have an excel sheet where I have a set 4 identical tickets to print per page which we use for stock takes. Rather then creating a huge document with 1000 pages for 4000 tickets each with their own unique ticket number (starting from 1) I would like to find a Macro or function which will print a page with 4 tickets on (1,2,3,4) then continue to print another with (5,6,7,8) and so on. I have found some code that people have already written but it has only applied to one number changing per page rather than 4 simultaneously and being a complete visual basic novice, I was unable to change the code to suit my preferences. If someone could explain simply how I could achieve this I would be very very grateful :)

  • Print out the amount of times 2 words appear in the syslog. But also have it tell me how many times for each hour

    - by wolfspinone
    So I'm trying to create a bash script that looks for two words in my syslog file. Then I want the script to print out how many times those two words have appeared. Also I want it to print it out for every hour of the day. So like if the word dog appeared 4 times during the first hour of today, it says Hour one, dog 4. Finally at the end of the script I want it to print out how many times those words appeared all day. The sudo code I have thus far is if 2 > hour find permit find block print both finish if 1 < hour < 2 find permit find block print both finish if 2 < hour < 3 find permit find block print both finish command is grep -o "\WORD\" Syslog.txt * | sort | uniq -c

  • Installing NVIDIA driver causes black screen (750M)

    - by aftrumpet
    I have a dual boot set up on a Lenovo Ideapad Y500 with NVIDIA 750M and I am having problems installing the graphics cards. I have made sure to install both linux-headers-generic and linux-source, and yet have ended up with a black screen whether I install nvidia-current, nvidia-current-updates, nvidia-experimental-310, and nvidia-319. I even tried enabling proprietary drivers through settings and still ended up with a black screen on boot. Is my graphics card just not supported yet, or is there a way to fix this?

  • Driver inversion

    - by Val
    I have a GUI game, which is driven by user every time it clicks the mouse. Every time user clicks a square on a board, the board state is updated (we re-compute the score, the player to make next move and legal movements it can make) and repainted. Both mouse click, state recomputation and painting are handled in the GUI thread. Now, suppose that I want to train AI to play without GUI. That is, game engine should consume next move by simply calling AI's makeMove function in one thread. This would allow to play millions of games per second automatically. GUI may just screenshot some arbitrary states time after time. How do you switch to this strategy?

  • All parts of my Printable Swing component doesn't print

    - by Jonas
    I'm trying to do a printable component (an invoice document). I use JComponent instead of JPanel because I don't want a background. The component has many subcomponents. The main component implements Printable and has a print-method that is calling printAll(g) so that all subcomponents should be printed. But my subcomponents doesn't print. What am I missing?

  • Strange Ubuntu Random Display [Video]

    - by d4v1dv00
    I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself. Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again. My wild guess is, should this be related to driver? Below are my detail system information: $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation H67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01) is there any other information i need to post and how do i do that?

  • Installing LBP 2900 ubuntu -> libs folders wrong?

    - by Peter Smit
    I am trying to get my Canon LBP2900 printer to work on Ubuntu 11.10 64 bit. What I have done is try to follow the steps on https://help.ubuntu.com/community/CanonCaptDrv190 So I downloaded the version 2.3 driver and tried to convert the rpm files to debian and installed them sudo alien cndrvcups-capt-2.30-1.x86_64.rpm cndrvcups-common-2.30-1.x86_64.rpm sudo dpkg -i cndrvcups-capt-2.30-1.x86_64.deb cndrvcups-common-2.30-1.x86_64.deb restarted cups and try to install the printer with lpadmin: sudo service cups restart sudo /usr/sbin/lpadmin -p LBP2900 -m /usr/share/cups/model/CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59787 -E What I noticed however that on the step with lpadmin it goes wrong with the error: lpadmin: Bad device-uri scheme "ccp" After trying to trace what has gone wrong, I think I nailed it to the fact that dpkg installed a file /usr/lib64/cups/backend/ccp instead of /usr/lib/cups/backend/ccp Checking the original rpm with archive manager shows indeed that /usr/lib and /usr/lib64 are used, with the backend/cpp file only installed in lib64. As I understand correctly, Ubuntu 11.10 uses /usr/lib32 and /usr/lib instead so the files are installed in the wrong place. Is there an automated method of converting the rpm/deb files with the wrong lib structure to one with the right lib structure for ubuntu 11.10? Or am I completely on the wrong track for getting my printer installed?

  • can't get a good install:11.10 server

    - by jack
    I screwed up my partitioning aparently tring to get lvm and raid1 going. the machine is an intel dual core dt with 2 gig of ram and 2 sata drives, one 250g and the other 500g. This a build for my school in n.e. Thailand. we have 20+ clients now, a website, email. Our old server is dying fast and we are going to add another 12 stations next week. I really need some help here! 1. have onboard gigabit ethernet that aparently uses same driver as realtek 811c. I installed a pcie gigabit card also 811c. At several points the eth0 has accessed the internet fine, but the eth1 will not communicate. 2. I saw a "fix" for this online which from root: rmmod r8169. this imediately killed the working onboard card. 3.I tried to re-install 11.10 figuring that would re-install r8169. However I messed something up in my partitioning and can't get a clean boot now. 6. so I think after 12 re-installs or so and 2 days. I can get through it right if I can start over with clean drives, but I can't figure out how to empty them out what with soft raid and lvm partitions. seems like i've had it going well and then trying to fix that one little problem, i go backwards.Please help! please send email.-thanks

  • May I open my own device driver twice simultanoiusly from a user program under Linux?

    Somewhere I read that opening the same file twice has an undefined semantics and should be avoided. In my situation I would like to open my own device multiple times associating multiple file descriptors to it. The file operations of my device are all safe. Is there some part of Linux between the sys call open() and the point it calls the registered file operation .open() that is unsafe?

  • What do I have to do and how much does it cost to get a device driver for Windows Vista / 7 (32 and

    - by Jon Cage
    I've got some drivers which are basically LibUSB-Win32 with a new .inf file do describe product/vendor ids and strings which describe my hardware. This works fine for 32 bit windows, but 64 bit versions have problems; namely that Microsoft in their wisdom require all drivers to be digitally signed. So my questions are thus: Is there a version of the LibUSB-Win32 drivers which are already signed I could use? If there aren't already some signed ones I can canibalise, what exactly do I have to do to get my drivers signed. Do I need to get 64 and 32 bit versions signed separately and will this cost more? Is this a free alternative to getting them signed? Are there any other options I should consider besides requiring that my customers boot into test mode each time they start their machines (not an option I'd consider).

  • Windows 7 Seems to break SWT Control.print(GC)

    - by GreenKiwi
    A bug has been filed and fixed (super quickly) in SWT: https://bugs.eclipse.org/bugs/show_bug.cgi?id=305294 Just to preface this, my goal here is to print the two images into a canvas so that I can animate the canvas sliding across the screen (think iPhone), sliding the controls themselves was too CPU intensive, so this was a good alternative until I tested it on Win7. I'm open to anything that will help me solve my original problem, it doesn't have to be fixing the problem below. Does anyone know how to get "Control.print(GC)" to work with Windows 7 Aero? I have code that works just fine in Windows XP and in Windows 7, when Aero is disabled, but the command: control.print(GC) causes a non-top control to be effectively erased from the screen. GC gc = new GC(image); try { // As soon as this code is called, calling "layout" on the controls // causes them to disappear. control.print(gc); } finally { gc.dispose(); } I have stacked controls and would like to print the images from the current and next controls such that I can "slide" them off the screen. However, upon printing the non-top control, it is never redrawn again. Here is some example code. (Interesting code bits are at the top and it will require pointing at SWT in order to work.) Thanks for any and all help. As a work around, I'm thinking about swapping controls between prints to see if that helps, but I'd rather not. import org.eclipse.swt.SWT; import org.eclipse.swt.custom.StackLayout; import org.eclipse.swt.events.SelectionAdapter; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.graphics.GC; import org.eclipse.swt.graphics.Image; import org.eclipse.swt.graphics.Point; import org.eclipse.swt.layout.GridData; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Control; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Label; import org.eclipse.swt.widgets.Shell; public class SWTImagePrintTest { private Composite stack; private StackLayout layout; private Label lblFlip; private Label lblFlop; private boolean flip = true; private Button buttonFlop; private Button buttonPrint; /** * Prints the control into an image * * @param control */ protected void print(Control control) { Image image = new Image(control.getDisplay(), control.getBounds()); GC gc = new GC(image); try { // As soon as this code is called, calling "layout" on the controls // causes them to disappear. control.print(gc); } finally { gc.dispose(); } } /** * Swaps the controls in the stack */ private void flipFlop() { if (flip) { flip = false; layout.topControl = lblFlop; buttonFlop.setText("flop"); stack.layout(); } else { flip = true; layout.topControl = lblFlip; buttonFlop.setText("flip"); stack.layout(); } } private void createContents(Shell shell) { shell.setLayout(new GridLayout(2, true)); stack = new Composite(shell, SWT.NONE); GridData gdStack = new GridData(GridData.FILL_BOTH); gdStack.horizontalSpan = 2; stack.setLayoutData(gdStack); layout = new StackLayout(); stack.setLayout(layout); lblFlip = new Label(stack, SWT.BOLD); lblFlip.setBackground(Display.getCurrent().getSystemColor( SWT.COLOR_CYAN)); lblFlip.setText("FlIp"); lblFlop = new Label(stack, SWT.NONE); lblFlop.setBackground(Display.getCurrent().getSystemColor( SWT.COLOR_BLUE)); lblFlop.setText("fLoP"); layout.topControl = lblFlip; stack.layout(); buttonFlop = new Button(shell, SWT.FLAT); buttonFlop.setText("Flip"); GridData gdFlip = new GridData(); gdFlip.horizontalAlignment = SWT.RIGHT; buttonFlop.setLayoutData(gdFlip); buttonFlop.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { flipFlop(); } }); buttonPrint = new Button(shell, SWT.FLAT); buttonPrint.setText("Print"); GridData gdPrint = new GridData(); gdPrint.horizontalAlignment = SWT.LEFT; buttonPrint.setLayoutData(gdPrint); buttonPrint.addSelectionListener(new SelectionAdapter() { @Override public void widgetSelected(SelectionEvent e) { print(lblFlip); print(lblFlop); } }); } /** * @param args */ public static void main(String[] args) { Shell shell = new Shell(); shell.setText("Slider Test"); shell.setSize(new Point(800, 600)); shell.setLayout(new GridLayout()); SWTImagePrintTest tt = new SWTImagePrintTest(); tt.createContents(shell); shell.open(); Display display = Display.getDefault(); while (shell.isDisposed() == false) { if (display.readAndDispatch() == false) { display.sleep(); } } display.dispose(); } }

  • Flash CS5 AS3 drop shadow filter won't print

    - by Blake uburuDOTcom
    Hello all, I've tried searching quite a bit to discover why I don't seem to be able to print drop shadow filters from within Flash. I have trouble printing, but if the movieclip I want to print has or contains a drop shadow, that clip will print sans the drop shadow. Anyone have any insight as to why this might be happening? If you want to try it out yourself, here is the simple print code I'm using. Just put something inside contentmc with a dropshadow and print it. print_btn.addEventListener(MouseEvent.CLICK,printContent); function printContent(evt:MouseEvent) { var printJob:PrintJob = new PrintJob(); if (printJob.start()) { if (content_mc.width>printJob.pageWidth) { content_mc.width=printJob.pageWidth; content_mc.scaleY=content_mc.scaleX; } printJob.addPage(content_mc); printJob.send(); } }

  • How to write a generic USB Host Driver for Printers from various vendors?

    - by Ullas
    I want to develop a USB host on an embedded device that will talk to printers from various vendors. Drivers for the vendor specific printers would be available on PC which is ultimately communicating with printer but my device is facilitating this communication and needs to perform the basic handshaking/setup of the printer (i.e, it needs to know when the printer is connected, what are the socket IDs that needs to be opened for CTRL and DATA transmissions etc). All of these printers are supposed to comply with IEEE 1284.4 standards but I see that many of them vary quiet a bit. One approach I have is to take the USB traces of handshaking from each of these printers and write various sections of code respectively (I know, that sounds ridiculous!). Is there a generic way to do this? Is there any available forum where these standard informations are mentioned? For eg: EPSON uses 'EPSON-CTRL' and 'EPSON-DATA' for its control and data services which needs to be provided to get the socket ID for these services. I am pretty sure HPs, Canon's etc would have their own service names as well. As per the standards, this was supposed to be captured in IANA but I dont see anything there. Any help on this would be greatly appreciated. Thanks and regards, Ullas
