Hi everyone, I use visual studio for day to day programming (read putting food in my mouth) but for personal programming (read c/c++ hacking) I use Emacs. Right now I am doing a programming exercise involving the X11 API. I am continually referring to the programming API manual to find the signature of function calls. What would be r...
In the NVIDIA README for the Quadro card X driver, there is this comment: Workstation overlays, stereo visuals, and the unified back buffer (UBB) are incompatible with Composite. These features will be automatically disabled when Composite is detected Is there some fundamental X reason why this is so? Why are quadro cards ...
Hello folks. (not sure if this question belongs here or to superuser) I'd like to know if there is any way to determine a terminal's background color ? In my case, using gnome-terminal. It might matter, since it's entirety up to the terminal application to draw the background of its windows, which may even be something else than a plai...
I have some unit tests that need an X11 display so I plan to start Xvfb before running them, but to start Xvfb I will need a free display number to connect it to. My best guess is to see what's free in /tmp/.X11-unix but I'm not sure how to handle the race if many tests try to start simultaneously. sshd must do this, does anyone know ho...
Hello, Some one know what are development packages for X11 for CentOS 3? Thank you for ahead ...
I'm used to most X11 apps that copy'n paste with a simple middle mouse key. In vim I must remember to hold the shift key. Is there any way in vim to copy'n paste using the mouse without the shift key? ...
using gdk_screen_get_monitor_geometry (xrandr) I can get the resolutions for separate monitors (for example when there are 2 monitors used as a single screen like nvidias twinview) However _NET_WORKAREA seems to give one giant area even if the resolution of the other monitor is smaller. (a panel at the bottom of the second monitor woul...
I'm learning about AI and (just for fun and practice, not profit or anything evil) I'd like to write a little bot to play a rinky-dink Flash game for me. As a Microsoft hater, I'm embarrassed to say that I know and have used the required function calls some time ago under Windows, programming in Delphi. But these days I try to do everyt...
Hey all, I'm running Ubuntu 9.10 and trying to run a Java program I wrote whose source code is located on a remote machine. I'm using ssh to connect using the following command from the terminal: ssh -X username@hostname When running the program, one of the GUI frames has its buttons missing from view, but they are clickable and work...
Hello everyone, I'm looking for a way to determine if the user switches virtual desktops under X11. I'm using Python with X11 libraries and PyGTK. I found some working examples in C, but I lack the expertise to translate them into Python, and I read the source code of several X11 pager applications (fbpanel, pypanel), but I can't seem ...
Hi, I'm writing some low level code for X11 platform. To achieve best data copying performance I use XFixes/XDamage extensions. How can I clear the contents of XFixes region after one refresh cycle? Or do they clean themselves after I use XFixesSetPictureClipRegion? My code is something like that: Display xdpy; XShamPixmap pixmap_; ...
I have written a GTK+ application but I am getting the following X Window error while running it: The program 'TestApp' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 222 error_code 8 request_code 2 minor_code 0)...
I'd like to be able to raise another application's Window using Python. I did see this, which I suppose I could try: http://stackoverflow.com/questions/1028972/x11-raise-an-existing-window-via-command-line However, I'd prefer to do it in Python if at all possible. ...
What is the best way to deal with fonts in a multi-platform distributed system? If I want to use a common font across all systems to show to the user, what's the best way to do this. From the little I've been reading each platform looks to have fonts that are of the same family (ie serif, sans-serif) but with different names. CSS look...
I need to multicast an x11 application window to multiple (sai 100) clients in a lossy (wireless) environment. Right now, I was able to do it through screen grabbing (vlc) and h264 compression, but there should be a cleaner solution, something along the lines of a multicast NX session. Is there anything which could work with some glue,...
Hi, I am trying to make an arcade machine. The user will purchase credits, which will allow him to play for X minutes. I want to write "9:42 minutes left" at the left corner of the screen, even if he's playing a full screen game (UrbanTerror, for example). I would really like if I could do this with Ruby, but any other language is OK. ...
I've got a XImage retrieved by XShmGetImage function. How can I resize it? Is there any function in X11 libraries to perform this operation or I need to use external library? ...
I have an x11 display with a windowmanager (sadly not a specific one, could be twm, dtwm, mwm, metacity …) , myApp and other applications with windows. I want to close the display if the other applications are closed and myApp is the only one with windows on the display. I do know the windows of myApp, but how do I distinguish between th...
Here's the deal. I logged into a Linux box (CentOS, but that shouldn't matter) as user A. I had to build a program as user B, so I started up a terminal shell, logged into that shell as B, and built it. When I try to run the app, I get this message: "connect to ":0.0" refused by server" Most likely because the current X Windows session...
I want to use shift-tab for auto completion and shifting code blocks visually. I have been referring to Make_Shift-Tab_work . That link talks about mapping ^[[Z to shift-tab . But i don't get ^[[Z when i press shift-tab. i just get a normal tab in that case. It then talks about using xmodmap -pke | grep 'Tab' to map tab keys. Accordin...
