OpenSUSE Hardware :: Quickcam E3500 - Colors Flicker Wildly In Separate Parts Of Image
Apr 15, 2010
I get a window that shows a broken image which shifts to the left in bits - top half, bottom quarter, etc. - and the colours flicker wildly in separate parts of the image. The shell from which it was launched gives this output: Any of the controls I try gives me errors, such as:
Set Auto Exposure on error
Set Auto Exposure on error
Set Auto Exposure on error
Set Auto Exposure on error
I closed this program and ran kopete, which showed me no image at all but gave this output on the shell: Calling appendChild() on a null node does nothing. Calling appendChild() on a null node does nothing. Calling appendChild() on a null node does nothing.
When playing dvd's, vob files and wmv files, the image comes with high contrast colors ,very intense red/green/blue. very dark too. I have vlc 1.1.4 installed, using ubuntu 10.10, libdvdcss2 installed. for the rest of the video formats it seems to work fine. any ideas on what should I start debugging?
I have a USB Logitech Quickcam (not sure what model) and I'm trying to simply get some live video running in UCView. I've compiled a bunch of device drivers into my kernel, including Video4Linux, Quickcam BW and Quickcam Colour (some logical choices). However, I am unable to get anything from my Quickcam. Regardless of whether the camera is plugged in, I can run UCView and get a video of scrolling colors, like the attached picture.
This is coming from /dev/video0. I just don't know how I can somehow hook up my quickcam to a video device.
on my dell xps M1530 dualcore duo 2.2GHz 4GB ram 500GB harddisk suse 11.3 KDE 4.4 and KDE4.6beta1, when I copy big or a big number of files (20 or 30 files 500MB each) dolphin slow wildly down, especially when I copy from a smb:// to my disk, dolphin start immediately to copy but when I click on a tab or a folder (a one that I didn't opened before) dolphin shows it to me after a couple of minutes, is it possible to solve??
I have the scanner HP Scanjet 2400 installed on a machine with K/Ubuntu 10.10 and I use the software Simple Scan to scan image. Problem: The image scanned by this scanner comes with a inversion of colors (what was supposed to be orange is blue ; the white sheet of paper that I've put inside it was not in the blank color when I scanned it too)... My Question: Is this a configuration problem (I did not configured this scanner at any way, so it's working by the Ubuntu drivers itself without my intervention)? Is there any way to solve it?
openSUSE 11.3 KDE There is a frequent flicker on my screen. Some application OR notification just pops and disappears( giving an impression of a flicker ). How do i find out which application OR notification is it.
1. When playing flash videos in firefox, they'll flicker with black screen flashing for a split second over the video(This continues throughout the video)
2. However, if I do either of the following, the flicker goes away (only while doing one of these actions):
a. Continually move the mouse over the video (i.e. move back and forth in a "mouseover")
b. Put the mouse over the scrubber circle (which shows time lapsed and allows dragging to change location in video) such that the "hand" cursor appears. Once the cursor changes back to a pointer, it flickers again. but as long as I move the mouse over the scrubber circle, it'll stop the flickering (even without moving the mouse anymore) until the circle passes beyond the cursor again.
I recently upgraded my desktop to 11.4 and kde 4.6.1 My desktop has : VGA compatible controller: ATI Technologies Inc RS690 [Radeon X1200 Series] This is legacy ATI stuff, radeon driver loaded (as was in 11.3) and seems to be operating. I am getting a somewhat periodic (5 secs or so) flicker on the display, fast enough to be annoying but not fast enough to really affect anything.
I have seen several threads about short freezes, but realize that flicker and freeze might be a matter of speed and memory, etc. I tried suspending Desktop Effects, that may have reduced the frequency of the flicker but did not eliminate.
I recently installed Ubuntu 10.04 Netbook Remix on my Gateway LT3103u. I noticed shortly into using it that it has a graphics bug every so often. Especially when I change the background image. Everything will change to a warped mix of colors and pixels. Everything is affected. My mouse, the bar at the top of the screen, text and all. My netbook runs on an AMD Athlon 64-bit processor with ATI Radeon X1270 HyperMemory up to 256MB graphics.
So far I have tried reinstalling, and even the 64bit desktop edition which had the same problem. Ive noticed that it freaks out when i scroll too quick, when changing background images, and on certain websites. Then other times its completely random. When it happens it looks similar to these: [URL]
I've got a Logitech QuickCam Communicate STX webcam. According to this website, this webcam works under Linux; however, when I open Cheese, I get only a screen full of colored bars (like what you see on a television channel that's off-air), and in Skype I get green snow.

Somewhy it is using YUY, but not MJPEG, although seems MJPEG can give larger resolution. How to get it? Single shot 1,3MPix technically possible, any way to do that?
Inspired by some recent posts from oldcpu I decided to grab some audio from my Logitech webcam, just for the fun of it. openSUSE 11.3 i586 is in use.
Code: > lsusb Bus 002 Device 003: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks > arecord -l **** Liste der Hardware-Geräte (CAPTURE) **** Karte 0: Intel [HDA Intel], Gerät 0: ALC892 Analog [ALC892 Analog]
It works! Though I have to say that the audio quality is mediocre (to say the best). I blame it on the quality of the built-in microphone of this camera. It sounds like it was recorded in a giant bathroom.
Is there a way to enable the top parts and the borders of windows in openSUSE to be partially transparent? If so, I'd be grateful if someone told me how. Like in this image, the top part where it says "Mozilla Firefox" and the border of that window are all partially transparent (yes, I know that's Windows, lol). I'm running 11.4 KDE.[URL]..
Attempting install of 11.3 on previous 11.2 dual windows boot box. I want to format the Linux parts including /Home and retain the Win / NTFS part. (dual boot) Peculiar behavior of install DVD. Here is fdisk -l that clearly indicates a 500 GB HD and the Win partition, extended partition and the 3 basic Linux partitions and they seem okay in total.
Linux-mocx:/ # fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x252d252c
I aborted the installation. What could possibly cause the 11.2 parts and bootloader to get this wacked up ? Outside of some sound issues the 11.2 install works okay for the most part. No crashing or lockups. Really want to get up to 11.3. though. I obviously have some work to do with 35 GB of missing space on the HD and Grub living someplace on the wrong side of the river. Suggestions and a pointer or two would be most welcome guys. ( I really don't want the pain of installing that �other� OP system or I'd reformat and reinstall nice and clean.) Do I need to repartition, change mount points and reinstall Grub maybe.
I am hitting a wall here - with the new 4.4 installed and working well, the one thing that is killing me is not being able to read the active taskbar item or the plasma peanut menu (see screenshot. You can see that the firefox and gimp are "active" and too dark to read, while kwrite is inactive and readable.They are BOTH too dark, and I cannot seem to find the option that controls those color elements.
I am not sure if this is the right place for this or not, but I am having a problem getting my HP6300 series all in one printer to print photo's with proper colors, all colors seem to run. I have hplip installed and set up to print photo's and it still prints colors like runs instead of correct.
I have two problems related to color scheme. First, is there any way to prevent web browsers from using the system's default colors? I use a dark scheme, specifically Obsidian Coast in KDE and Industrial in GTK. This doesn't behave well on web pages in Firefox, Arora, and Konqueror. (Opera is fine.) Sometimes a site's stylesheet will specify a text field's text color to be black, but its background is not specified, so it defaults to black-on-dark-gray. I've also seen such a field's background color specified as white while the text color was not, so it ended up being light-gray-on-white. Is there any way to keep browsers from ruining web pages? Also, even if the stylesheet doesn't specify the colors, the dark text fields and buttons still stick out like a sore thumb on a warm or bright page.
My second problem is this: I have a saved session that brings up my applications every time I log in, but the GTK apps Pidgin and Evolution don't match the GTK color scheme until I quit and start them up again. Is there some way of fixing or working around this problem?
When I execute Eclipse or Firefox remotely using ssh (on a LAN using ssh -Y user@remote-machine eclipse) they both look strange, the colors are kind of yellow. Logging in to the remote machine using NX or VNC and executing the same apps does not produce the same colors, the apps look fine. Executing the same apps on my local machine does not produce the strange colors either.The remote machine is a SLES 11 and the local is a openSUSE 11.3 (with KDE 4.5.2).This might seem like a small problem but it is annoying to work a whole day like this when the remote apps looks like **** on my otherwise beautiful KDE desktop
I have used Ubuntu and Linux Mint for quite some time now until I got a new machine. Some friends told me to try OpenSUSE because it has really been polished over the last few years.Install went smoothly got everything working properly except for my video card. My video card is an ATI HD4890 with sound support over HDMI. I had the sound working in Ubuntu using the non-oss ATI drivers. I was wondering if someone could please teach me how to install them again here on OpenSUSE 11.3. My screen fonts and colors also look terrible compared to Windows or Ubuntu.
Is there a way I can make it look better? I remember CCC (Catalyst Control Center for ATI) had two color formats (RGB and YCbCr). I had to set it to YCbCr because my screen is an HDTV and it looked much cleaner than RGB. Is there a way I can acheive similar results with OpenSUSE?
I'm using gnome 2.28 on opensuse_x86_64 on hp dv9000. Cannot remember (last time I used this was 10.3 w/KDE) how to remove icons, etc. so that each workspace (I use defualt 4 each) has a different "set-up" IOW I don't want default icons and such on each workspace, but don't see a means to do this in gnome-control.
P4 2.4gHZ 2.0GB Ram I have tried to do some reading on this by googling and such, but it is all a bit overwhelming and so many posts/articles want to deal with dual booting which I am not planning to do on this machine. I am trying to find some info on whether it is better to have a separate boot partition. As in, separate from root partition. I have read that a separate boot partition makes for a quicker start and better recovery if system crashes. I will shortly be installing openSuse 11.2(KDE) [currently on 11.0] and I want to optimise the partition scheme so that it is the most efficient. I have a 160GB HDD that will be housing this new installation, so space is not a problem. I am only user on this machine. Currently, it is just partitioned as such:
2.0GB - swap [because I read it should equal Ram] 32.0GB - / 40.0GB - /home 76.8GB - extra storage [Not really necessary as I have 2 other HDD on system 1 - 320GB and 1 - 200GB]
Also, is it recommended to have separate partitions for /tmp /var or any other /nnn ?
I want to get into the Linux world and trying to install openSuse 11.3 on a separate partition, so I can start getting familiar with it. Installation started and PREPARATION was OK. INSTALLATION WAS OK. While doing Automatic Configuration after a little while the program stops (it hangs). I have to restart the computers by pushing the hdw reset button.
At next reboot, at the partition menu I choose openSUSE option; the program starts and after a while it says that previous installation failed and ask me if I want to retry. I do choose yes, but than again same thing happens - hangs and does not complete automatic configration (which by the way seems to be the last step of the installation). PC is a 2,8GHz, 1GB RAM, Windows OS XPHome and Service PAck3, and now partially loaded openSUSE11.3. OS
I have a dual boot system with Vista and OpenSUSE 11.3 . Linux is distributed over 2 partitions: one for /home and one root partition for all the rest. As this root partition is getting filled, I thought of taking a 10 GB partition from the Vista partition and using this for the /usr folder (= 6 GB). This partition is a primary partition, while the rest of Linux is on secondary partitions.To be save, I renamed the existing /usr to /usr-old and created an empty /usr as mount point. I changed fstab to load the root partition, the /usr partition and then the /home partition.But when I started the system, there were a lot of errors about files not found in the /usr folder, lthought this folder and is content were clearly present when browsing the filesystem. What went wrong? Hard links? Other system configurations to change? Not possible to put /usr on a separate partition?
I switched from 11.1 to 11.2 last month. I'm now having a smoother experience with openSUSE, with some exceptions.
One is Emacs. A rather annoying "feature" that has appeared is the following: When editing a LaTeX file, compiling it (C-c C-c, using AucTeX macros) makes the Emacs window become shorter by one line. The same happens if I switch to some other buffer. It does not happen if I switch back to the LaTeX buffer. So, after just a few editing/compiling/checking errors sequences I find the original window half of its initial size...
A similar problem occurs when editing IDLWAVE scripts (it's a proprietary scientific data analysis language widely used in my field, but still has its Emacs macros), but only if I open an interactive IDL-shell to run the script.
So, I imagine it's not a problem related to AucTeX, although it might be related to the macros opening separate buffers/windows (e.g.: error messages) associated with the current buffer. Also, the problem does not go away if I remove my own .emacs customization files. Checking the Emacs bug lists, it seems that there are some bugs related to window resizing, although I have not been able to find exactly the same problem I am having. But, before reporting this one, I'd like to hear from fellow Emacs/openSUSE users. Just in case I'm messing things up somehow.
Currently using: Emacs v 23.1.1 Some more info: Dell Precision M65 portable workstation, NVIDIA Quadro FX1500 using the binary NVIDIA driver). Using OpenSuse 11.2 + KDE 4.3.1
