Ubuntu :: Pixel Dimensions For Panels?
May 9, 2011
Does 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.

Whenever I log in, restart, etc... There are no panels shown, I have to alt+F2, open terminal and run killall gnome-panels in order to have panels shown again. Is there a way to fix this?

I 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.

I want to list the images in a directory with their dimensions, if possible in order of their widths (all the wider pictures come first) - this is not strictly necessary,

A while ago, while moving my LCD monitor, something struck the screen causing some pixels to go black. Months later those pixels grew to a long vertical stripe down the right side of my screen. I'm constantly having to move pallets out of the way so I can see what I'm doing.
Is there a way to change the geometry of the X server to be something like 1800x1080 instead of 1920x1080?

I'm running Fedora 13 (fully updated) with Firefox 3.6.3 and I'm noticing that Firefox isn't remembering window dimensions across launches (eg. I have to resize Firefox everytime I run it). This is affecting the main Firefox window as well as the bookmarks window.

I'm not afraid of bash but I'm not very good with it either. I'm assuming there's a way of using find, perhaps in conjunction with another tool, to find images in a directory (and subdirectories) based on their dimensions?
Specifically, I want to find all the landscape-oriented images and copy them somewhere else.

I am experimenting with attaching a second monitor to my Ubuntu Natty laptop, and I have noticed an annoying "feature" that makes any multi-monitor setup so unusable that I actually prefer my single-monitor laptop setup. It appears that the system automatically "scales" the X- and Y-axis sensitivity of the touchpad to match the dimensions of the "virtual" screen that spans across multiple monitors. This is best illustrated with an example. If I set up two monitors side-by-side, the touchpad's X-axis speed is doubled, so that moving my finger the same distance on the touchpad causes the mouse on the screen to move twice as far in the X direction as it did when I had only a single monitor. Yet the Y-axis sensitivity remains unchanged, so all diagonal mouse movements end up at the wrong angle. This makes the touchpad almost completely useless, since the mouse on the screen does not move in the same direction as my hand on the pad.
Is there anything I can do about this? I just want the X- and Y-axis speeds to be identical, and I definitely don't want my mouse sensitivity changing because I added a screen. The touchpad is a Synaptics touchpad, by the way. The laptop is a Dell M1330 with an nVidia graphics card.

I 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)?

I'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.

Did anyone else notice in the 10.04 RC that it is very difficult to expand a window from the left or right side? The threshold is one pixel long before the arrow disappears.

I've upgraded (though at this point it doesn't quite seem like an upgrade ) to the Natty and have had a pretty good load of issues*.
I've gotten the system to a working state, and things seem ok, aside from this:
Screenshot.png
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.
*I've had to switch over to the classic view, roll back my nvidia video drivers, and reinstall mozilla shredder/sunbird.

This is the first time I have pixel errors when using my setup in linux, have resently installed the debian squeeze rlz, with rglrx drivers from the debian wiki how to.
Now I have pixelerrors in pictures and they are static for the pictures aka, the pixels are static in the picture even if I move a webpage for instance.
Any buggreport on this? Or how to fix it, its hard to make a screendump but I could take a picture of the screen with a cam if someone like to see it
In win7 or ubuntu there is no indications of this problem.

I am trying to stream from a webcam to mp4 file with avconv/ffmpeg with the GRBG pixel format. I can find a lot of ffmpeg commands and other stuff on google about a webcam stream to file with ffmpeg, but none of them use GRBG pixel format and are working for me ...
I have never tried something like this before
Output of v4l2-ctl --list-formats-ext:
Code: Select allioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'GRBG'
Name : GRBG
Size: Discrete 162x120
Size: Discrete 324x240
How to get this working?

I was wondering if theres a commandline prog that could give me an 'X' (like xprop does) so that I can point to a particular pixel and it give me the X and Y cordinates of that pixel?

I 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?

I have been happily running Wheezy on the Chromebook Pixel with little or not issues. Recently I needed to re-install and decided to try Jessie. Again I was following the excellent instructions at [URL] .... except with the Jessie image.
However everytime I went to install it (after adding in the mem=4G line) it just rebooted and brought me back to the same install screen again. I just downloaded the Wheezy image again and it is installing now perfectly.

Recently, 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?

I'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.

I manipulated the two pannels, making them to automatically hide, then changing one of them to the upper side...
Suddenly it stopped working, I could not complete the change, and on the next restart no panel show up!
I guess I need to reset the configuration of gnome-panel or something, but I have no idea how to do so.

I followed the instructions in this guide to get the plasma workspace without having to migrate to kde:http://digitizor.com/2010/01/01/how-...28Digitizor%29All went well, I was able to complete all the steps in the guide, and I double clicked the "plasma workspace.sh" and it launched the plasma workspace fine.Then I tried using the gnome-desktop.sh the same way, but it just started the gnome desktop and quickly reverted to the plasma workspace. So I looked at the commands in the plasma.sh and the gnome.sh, and the commands on the guide page, and noticed they were the same for both shell scripts. So I changed the gnome desktop.sh from:
#!/bin/bash
killall fusion-icon
killall gnome-panel
