Hardware :: Pixel Errors In Pictures With Ati Drivers?
Jan 3, 2010
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.

Running Ubuntu 10.10 along side Windows7 on a 64-bit HP Pavilion dv7 Laptop. Everything works in Windows. Everything works in Ubuntu, except for 2 things.1) I can live with not being able to enable/disable wifi.) I cannot read photos from an SD card plugged into the laptops SD card reader. When I open the SD card in Ubuntu, I can see the file name, but the thumbnails show messed up pictures. Usually, the bottom half of the photo is solid green, and there are usually lines running through the photo, or it is divided into quadrants with one quadrant being ok, but the rest having the green and/or lines.I assume the driver for the card reader is not correct. Card reader works fine in Windows. So I have to reboot into windows, copy pictures from reader to a folder, then reboot into Ubuntu and I can see and open the photos just fine. Just cannot read and copy them from the card while in Ubuntu.

I am having problems with a cd/dvd drive and I would like to know if it could be a driver problem or what?
I can boot from cdroms but I almost always have problems mounting the cdrom's filesystem.
The laptop has been working for years with the same ubuntu release (hardy) but there are always a couple of warnings during boot time saying that certain drivers should be updated but I don't know how.
These are the persistent messages from dmesg output:
Code:
[ 12.693449] Driver 'sd' needs updating - please use bus_type methods
[ 12.700371] sd 0:0:0:0: [sda] 156301488 512-byte hardware sectors (80026 MB)

I've made the real mistake of buying a laptop with a Broadcom wifi adapter on it. (That thwacking sound is me kicking myself for not noticing after spending weeks and weeks carefully choosing the model I wanted.)
lspci gives this:
02:00.0 Network controller: Broadcom Corporation Device 4727 (rev 01)
I have downloaded the 32 bit drivers from here (am running Mandriva 2010.1 Free 32 bit). The readme indicates the 4727 is supported by the latest OS drivers amazingly. [URL]. I have installed the Linux kernel source files.
First problem comes with the first instruction in the readme.
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar or <path>/hybrid-portsrc-x86_64.tar.gz
The tar instruction just does nothing, so I just right clicked in Dolphin and unpacked it to its own directory. I navigated the terminal to where it unpacked and did make. I got this:
Code:
[robertw@localhost hybrid-portsrc-x86_32-v5.60.48.36]$ make
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`

Sometimes, in Firefox, after looking a video and closing the corresponding tab, a still picture of the video appears in other tabs, even in some other applications than Firefox (e.g. Terminal). I've installed the nvidia drivers on Fedora 14. They seem to work properly.

So xorg was acting up, and I went into the Hardware Drivers menu to see if the driver had a problem. The driver was disabled, and could not be activated. I downloaded the new ATI driver. I uninstalled the old one, installed the new one, and ran the config step just like it specifies in the install instructions. Upon reboot, I got a blank screen instead of the login screen.I managed to drop back to the command line and uninstall the driver, so now I'm stuck in ubuntu with one monitor instead of 2.
I'm going to attempt to revert to the old ATI driver (which I still have in my home dir), but I wanted to be sure to get this into the forums before I ruined my GUI again.

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)?

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.

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.

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?

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.

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.

I have a Dell Vostro 3300, i5 460 processor with a NVIDIA 310M Graphics Card. I'm doing a KUBUNTU 10.10 (Maverick) install with the following results. The Live CD boots just fine to, "TEST," or "Install." Installation goes fine. However, the graphics card being used is the Intel i915. I have tried installing the NVIDIA drivers directly from the, "Additional Drivers," tool and after the reboot I get through the boot screen to the console. I try to manually startx and I get the errors, "no device found," "no screens found." The second install I tried purging and blacklisting the nouveau drivers and entering safe mode. Then using apt-get install nvidia-current. After that, nvidia-xconfig. Same results.
The third attempt I re-installed and this time downloaded the drivers from the Nvidia site (version 256.53). Blacklisted nouveau, remove all nvidia, updated initramfs, etc. The install went fine however I still end up at a console after boot with the same messages as above. No device found, no screens found. I've tried searching through the forum and web and have tried things like adding the modset option along with many other hacks, tips and fixes. still, no go.I can live with the Intel graphics for now although I lose 512MB of memory. Unfortunately there is no way to disable or change this set-up in the BIOS. I've seen quite a few bug reports at Launchpad:
1. Is this something I should just wait til a fix comes? Will a fix come?
2. Is there, or will there be an official Updated Ubuntu Guide for Maverick to install NVIDIA drivers with this tecnology?
3. Lastly, is there anything else I should try??

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.
