Fedora :: 14 - Logon Screen User Order ?
Nov 4, 2010In fedora 14, the user order on GNOME login screen is completely different from that in fedora 13. Is there any way to order the users by date of creation ASC, not by name ASC?
Also, it is completely random. This time when I started my computer, my account was listed first. When I started this thread, it was listed last. What's happening?
OpenSUSE Install :: Username Order On Login Screen In 11.2?
Dec 2, 2009I just moved from openSUSE 11.0 to 11.2.
While I like to new login screen (I was using a face based theme previously), I am stumped on how to control the order that the user names are presented.
As best I can tell, they are presented in the order who logs in most frequently. While that makes a certain amount of sense, I would like to be able to force the list to remain alphabetical.
Is there any way to control this, and if so, where?

Ubuntu :: Unable To Dim The Screen In Order To Save Power - Listen To Music Or Any Other Sounds Through Headphones Or Speakers
Jun 25, 2010Ok so I am a total newbie at Ubuntu Linux and I'm having problems I don't know how to solve.
1.) Up until yesterday this wasn't a problem, but after a power outage while I was connected I am now unable to connect to the internet anymore as it says "Networking is disabled", how do i enable the "networking"?
2.) Another problem I am having is that I am not able to dim the screen in order to save power among other uses, I've looked around but haven't been able to find a solution, I am running ubuntu on a Gateway M-Series Laptop.
3.) Finally, since installing linux I have been unable to listen to music or any other sounds through headphones or speakers, when i connect something into the audio output, the outer speakers do shut off but no sound is emitted through the speakers/headphones, and yes i have tried multiple ones to make sure it wasn't the headphones or speakers.
Ubuntu :: Stuck Pixel In Program?
Nov 20, 2010I thought it was just a normal stuck pixel the first day I saw it, but then I noticed if I move opera around the screen they stay with opera. It doesn't occur with any other programs, only opera. These pixels also show up when I take a screenshot. Is there a way to get rid of these pixels (or whatever they are)?

View 1 Replies View RelatedUbuntu :: Pixel Dimensions For Panels?
May 9, 2011Does anyone know the pixel dimensions for the panels.I want to design a panel background image in gimp for the entire panel but I don't know how many pixels they are from left to right. I know (or I think) that they are 24 pixels from top to bottom but how many across?
I have designed images to use as panel backgrounds but they tile so it's like one consistent thing as I don't know the dimensions for the length of panels, only the 24 pixel height. I've attached a couple so try them out, they're pretty cool.
Ubuntu :: Mouse Pointer Causes Pixel Error
Jan 28, 2010I've just installed Ubuntu 9.10 on my wife's old notebook, a Sony Vaio PCG-FX705, by wiping the HDD (i.e. no more Windows ). The problem is that there's some weird display error that reminds of a TFT with pixel errors, although that's no the cause. I got a screenshot of it here (made with a digicam), and here is a close-up of it.
One thing I've noticed is that this error starts at the mouse pointer's tip and goes right when the computer is booted. Also, when using Blank Screen as screensaver, the error disappears once the screen went blank until I press a key or move the mouse, at which point the error will re-appear at the mouse pointer's current location. The only way I found so far to temporarily fix this problem is to change display resolution. It doesn't matter which resolution I use, all that matters is that I change it.

I've gotten the system to a working state, and things seem ok, aside from this:

I've got a few applications (Skype, etc, etc) that are now squished into a single pixel in the notification area. I can right click on it and get the context menus from them, but that isn't exactly the greatest solution.

Feb 17, 2010I am trying to scroll text from a text file across a wx.panel. This is the code so far:
Code:
def scrolling(self, text, rate):
def scroll(): charList = []
dc = wx.ClientDC(self.panel_1)
open_text = open(text, "rb")
my_text = open_text.read()
charList.append(my_text) open_text.close()
x,y = self.panel_1.GetClientSizeTuple()
while 1: for z in charList: for r in range(2000):
dc.DrawText(z,x-r,0) time.sleep(rate) dc.Clear()
net3 = threading.Thread(target=scroll)
net3.setDaemon(1) net3.start()
It scrolls but I am guessing where the range is (2000). I need to be able to determine the total number of pixels that the text in the file is. Is there a python way to determine this?
Ubuntu :: Two Panels At Screen Top - Panels Lose Order On Reboot
May 12, 2011I find that I prefer have both panels located at the screen top. That way I don't have to go to the bottom of the screen for one thing, then back to the top for another. I arranged the panel so the regular top one is on top,then the panel that contains the open applications is underneath.The problem is, when I reboot, the panels lose their order. First, the regular top panel initializes, then the bottom ones starts and pushes the first panel down, which becomes what you see in the picture: I would like to find a way to keep them in the opposite order of what you see in the picture, but every time I reboot they end up in that order.

Debian Installation :: Jessie Netinst Fails For Chrome Book Pixel

View 3 Replies View RelatedUbuntu :: Top-right Single Pixel Is No Longer Part Of "Close" X
Oct 28, 2010Recently, I loaded the new Ubuntu 10.10 - the Maverick Meerkat
Like many others, I'm sure, I run my mouse with the speed of light. So, I often zip my pointer up to the top right corner, hitting the virtual "wall" and landing on the very top right pixel, and click - expecting that the window will close. In the new 10.10, the top right pixel is not included in the mighty "X" button in any theme I have tried. So, now I have to exercise some precision and move a little down/left to click my close button. It is an annoyance that I'm simply not willing to accept any longer.
For the life of me, even though I am a 4-year Ubuntu user, I have never had much reason to play with the themes or make a change like this, and I can't seem to figure out how to fix it.
how to adjust the theme / border / title bar such that the close-window "X" includes the top right pixel?
Programming :: OpenCV - Pixel Format Of Incoming Image Is Unsupported By OpenCV
Nov 6, 2010I'm using a logitech quickcam pro 3000 on Ubuntu 10.04.
When I run a simple program with OpenCV to display the output from a camera I get the following output:
Code:
A window still opens with the output from the camera, but it seems very low quality and has far less pixels then it should. The camera built into my computer runs the same program with no problems.
My code for the program is simply:
Code:
One further note to make is that I still have the bad quality and low number of pixels with the logitech even when using webcam program. I can seem to find any drivers to update or anything though.
Programming :: Xlib - C Programming - Get Value From Pixel
Dec 11, 2009I'm making a game with the xlib library. What I want to do is to know if the character is standing on a trap or something else.
So far I've solved that using the coordinates but when I draw circles or stuff not shaped like a rectangle it gets to hard to make the game exact.
So what I'm asking for is if there is some kind of function in the xlib that tells you which color a pixel has. Because then it'd be much easier.
I've searched but I haven't been able to find anything good. I found XGetPixel() but that appears to work only with images, maybe I can make my window to be an "image"?

So far I can only presume I have used the wrong terms to find how to determine which device the web cam is using.
