  • Problem with OpenGL or Unity, need Gnome fallback mode

    - by William Wind
    This question is in two parts, and I have been searching the web for days to find answers. With no luck I thought I'd drop by and ask for your help. Here goes: 1.) I'm running Ubuntu 13.04 and one day last week Unity suddenly wound't work. After the login screen, I was either faced with an all black and non-responsive screen, or sometimes it booted and I could see my desktop wallpaper (and add and remove icons/folders from the desktop). But there was no menu in the left hand side and no top bar :-( However I could still enter the terminal. I borrowed my dad's laptop and looked for a solution online. About two days later I gave up (I'm still kind of a n00b at Linux) and found a way to install Gnome Fallback, via the terminal. When I used it, I had the same problem. [clue #1] Missing menues. But if I rebooted into Gnome Fallback mode with no effects. It worked. Great! I have used that for some days now, while still trying to fix the original problem with either Unity or OpenGl or whatever went wrong in the first place. With no luck. After giving up on my search for a fix (I know that came out wrong) -- I decided to reinstall Ubuntu 13.04 from a CD. But! After that I was left where I began. When booting into my account, it only shows the desktop wallpaper and the icons. I can click and enter the folders, but not go into the menues. Last time I fixed it with Gnome Fallback mode, because I could enter the terminal and the PC was automatically online, via wireless network. But not this time, I can't get online. So: 1.) How do I via the LiveCD Ubuntu version (the one I'm using right now) install Gnome Fallback unto the harddrive based system? 2.) If impossible. How can I access the wireless Internet via the terminal, so I can install Gnome Fallback, from the "broken" Unity session. 3.) Is there any other things that I should try? Please help me, PS: My GFX-card is an ATI Radeon something and I have install and used the "Redwood" drive (I think its called) for many weeks prior to the shutdown.

  • Solving the context menu problem with drag and drop in trees

The same tree component also has a context menu defined that is shown when users select the tree with the right mouse button. The problem now was - and I could reproduce this - that the context menu stopped working after the first time the tree handled a drop event. The drag and drop use case is to associate employees from a table to a department in the tree using drag and drop. The drop handler code in the managed bean looked up the tree node that received the drop event to determine the department ID to assign to the employee. For this code similar to the one shown below was used List dropRowKey = (List) dropEvent.getDropSite(); //if no dropsite then drop area was not a data area if(dropRowKey == null){    return DnDAction.NONE; }                tree.setRowKey(dropRowKey); JUCtrlHierNodeBinding dropNode = (JUCtrlHierNodeBinding) tree.getRowData(); Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} So what happens in this code? The drop event contains the dropSite reference, which is the row key of the tree node that received the drop event. The code then sets the key to the tree in a call to getRowDate() returns the node information for the drop target (the department). This however causes the tree state to go out of synch with its model (ADF tree binding), which is known to cause issues. In this use case the issue caused by this is that the context menu no longer shows up. To fix the problem, the code needs to be changes to read the current row key from the key, then perform the drop operation and at the end set the origin (or model) row key back //memorize current row key Object currentRowKey = tree.getRowKey();        List dropRowKey = (List) dropEvent.getDropSite(); //if no dropsite then drop area was not a data area if(dropRowKey == null){   return DnDAction.NONE;   }              tree.setRowKey(dropRowKey); JUCtrlHierNodeBinding dropNode = (JUCtrlHierNodeBinding) tree.getRowData(); ... do your stuff here .... //set current row key back tree.setRowKey(currentRowKey); AdfFacesContext.getCurrentInstance().addPartialTarget(tree); Node the code line that sets the row key back to its original value.

  • Print Problem in Ubuntu 10.10

    - by Michael
    There are many different Print dialogs but one is very common and is used by Gimp, Shutter, Evloution and Simple Scan. In all these apps the "Page Size" and "Orientation" are disabled. The same dialog in Firefox, Thunderbird and GEdit works OK. I program in Gambas3 which uses this dialog in conjunction with the GTK+ library and it also has these options disabled. If I use the QT4 library then a different print dialog is displayed with no problems. Anybody else notice this problem and found a solution?

  • no login screen: problem with lightdm or plymouth?

    - by a different ben
    When I boot up my system, I don't get a login screen, just the boot log scrolling by, repeating after a while lines like this: * Starting anac(h)ronistic cron [ OK ] * Stopping anac(h)ronistic cron [ OK ] I can change to another virtual terminal, and start lightdm from there with sudo lightdm restart or sudo start lightdm. Other people with similar problems had just lightdm in their /etc/x11/default-display-manager. I've checked mine and it has /usr/sbin/lightdm in there, so that's not the problem.

  • The Problem Should Define the Process, Not the Tool

    - by thatjeffsmith
    All around awesome tool, but not the only gadget in your toolbox.I’m stepping down from my SQL Developer pulpit today and standing up on my philosophical soap box. I’m frequently asked to help folks transition from one set of database tools over to Oracle SQL Developer, which I’m MORE than happy to do. But, I’m not looking to simply change the way people interact with Oracle database. What I care about is your productivity. Is there a faster, more efficient way for you to connect the dots, get from A to B, or just get home to your kids or to the pub for happy hour? If you have defined a business process around a specific tool, what happens when that tool ‘goes away?’ Does the business stop? No, you feel immediate pain until you are able to re-implement the process using another mechanism. Where I get confused, or even frustrated, is when someone asks me to redesign our tool to match their problem. Tools are just tools. Saying you ‘can’t load your data anymore because XYZ’ isn’t valid when you could easily do that same task via SQL*Loader, Create Table As Selects, or 9 other different mechanisms. Sometimes changes brings opportunity for improvement in the process. Don’t be afraid to step back and re-evaluate a problem with a fresh set of eyes. Just trying to replicate your process in another tool exactly as it was done in the ‘old tool’ doesn’t always make sense. Quick sidebar: scheduling a Windows program to kick off thousands if not millions of table inserts from Excel versus using a ‘proper’ server process using SQL*Loader and or external tables means sacrificing scalability and reliability for convenience. Don’t let old habits blind you to new solutions and possibilities. Of couse I’m not going to sit here and say that our tools aren’t deficient in some areas or can’t be improved upon. But I bet if we work together we can find something that’s not only better for the business, but is also better for you. What do you ‘miss’ since you’ve started using SQL Developer as your primary Oracle database tools? I’d love to start a thread here and share ideas on how we can better serve you and your organizations needs. The end solution might not look exactly what you have in mind starting out, but I had no idea I’d be a Product Manager when I started college either What can you no longer ‘do’ since you picked up SQL Developer? What hurts more than it should? What keeps you from being great versus just good?

  • C# OpenGL problem with animation

    - by user3696303
    there is a program that simulates a small satellite and requires that a rotation animation of the satellite along the three axes. But when you try to write an animation problem during compilation: the program simply closes (shutdown occurs when swapbuffers, mainloop, redisplay), when you write the easiest programs have the same problem arose. Trying to catch exception by try-catch but here is not exception. How to solve this? I suffer with this a few days. Work in c# visual studio 2008 framework namespace WindowsFormsApplication6 { public partial class Form1 : Form { public Form1() { try { InitializeComponent(); AnT1.InitializeContexts(); } catch(Exception) { Glut.glutDisplayFunc(Draw); Glut.glutTimerFunc(50, Timer, 0); Glut.glutMainLoop(); } } void Timer(int Unused) { Glut.glutPostRedisplay(); Glut.glutTimerFunc(50, Timer, 0); } private void AnT1_Load(object sender, EventArgs e) { Glut.glutInit(); Glut.glutInitDisplayMode(Glut.GLUT_RGB | Glut.GLUT_DOUBLE | Glut.GLUT_DEPTH); Gl.glClearColor(255, 255, 255, 1); Gl.glViewport(0, 0, AnT1.Width, AnT1.Height); Gl.glMatrixMode(Gl.GL_PROJECTION); Gl.glLoadIdentity(); Glu.gluPerspective(45, (float)AnT1.Width / (float)AnT1.Height, 0.1, 200); Gl.glMatrixMode(Gl.GL_MODELVIEW); Gl.glLoadIdentity(); Gl.glEnable(Gl.GL_DEPTH_TEST); Gl.glClear(Gl.GL_COLOR_BUFFER_BIT | Gl.GL_DEPTH_BUFFER_BIT); Gl.glPushMatrix(); double xy = 0.2; Gl.glTranslated(xy, 0, 0); xy += 0.2; Draw(); Glut.glutSwapBuffers(); Glut.glutPostRedisplay(); Gl.glPushMatrix(); Draw(); Gl.glPopMatrix(); } void Draw() { Gl.glLoadIdentity(); Gl.glColor3f(0.502f, 0.502f, 0.502f); Gl.glTranslated(-1, 0, -6); Gl.glRotated(95, 1, 0, 0); Glut.glutSolidCylinder(0.7, 2, 60, 60); Gl.glLoadIdentity(); Gl.glColor3f(0, 0, 0); Gl.glTranslated(-1, 0, -6); Gl.glRotated(95, 1, 0, 0); Glut.glutWireCylinder(0.7, 2, 20, 20); } } }

  • Tiling Problem Solutions for Various Size "Dominoes"

    - by user67081
    I've got an interesting tiling problem, I have a large square image (size 128k so 131072 squares) with dimensons 256x512... I want to fill this image with certain grain types (a 1x1 tile, a 1x2 strip, a 2x1 strip, and 2x2 square) and have no overlap, no holes, and no extension past the image boundary. Given some probability for each of these grain types, a list of the number required to be placed is generated for each. Obviously an iterative/brute force method doesn't work well here if we just randomly place the pieces, instead a certain algorithm is required. 1) all 2x2 square grains are randomly placed until exhaustion. 2) 1x2 and 2x1 grains are randomly placed alternatively until exhaustion 3) the remaining 1x1 tiles are placed to fill in all holes. It turns out this algorithm works pretty well for some cases and has no problem filling the entire image, however as you might guess, increasing the probability (and thus number) of 1x2 and 2x1 grains eventually causes the placement to stall (since there are too many holes created by the strips and not all them can be placed). My approach to this solution has been as follows: 1) Create a mini-image of size 8x8 or 16x16. 2) Fill this image randomly and following the algorithm specified above so that the desired probability of the entire image is realized in the mini-image. 3) Create N of these mini-images and then randomly successively place them in the large image. Unfortunately there are some downfalls to this simplification. 1) given the small size of the mini-images, nailing an exact probability for the entire image is not possible. Example if I want p(2x1)=P(1x2)=0.4, the mini image may only give 0.41 as the closes probability. 2) The mini-images create a pseudo boundary where no overlaps occur which isn't really descriptive of the model this is being used for. 3) There is only a fixed number of mini-images so i'm not sure how random this really is. I'm really just looking to brainstorm about possible solutions to this. My main concern is really to nail down closer probabilities, now one might suggest I just increase the mini-image size. Well I have, and it turns out that in certain cases(p(1x2)=p(2x1)=0.5) the mini-image 16x16 isn't even iteratively solvable.. So it's pretty obvious how difficult it is to randomly solve this for anything greater than 8x8 sizes.. So I'd love to hear some ideas. Thanks

  • Problem connecting to certain wifi networks

    - by Romas
    I'm using lenovo u300s (it has Intel Centrino Wireless-N 1030 card), and I can connect to wireless network at home with no problem, but I can not connect to any networks at my university. I'm not sure if it's the case but most of university networks are open and you need to sign up your username as you enter browser. There is also an eudoroam network, but I can not connect to it either. Any suggestions? Yes I have the latest ubuntu version.

  • AMD Drivers problem

    - by Darthkpo
    So, I'm kind of new to Ubuntu and Linux in general, I installed the latest (Ubuntu 14.04) and everything went fine, except for the resolution so I thought that it was a driver problem because I have a AMD HD 7750 and maybe it required additional proprietary drivers so I installed AMD Catalyst (Latest version), and then rebooted. And now my monitor says Can't Display and I can't see the GUI. I can go to terminal (Pressing Ctrl + Alt + F1, F2, F3 etc) but Not the UI.
