I'm not sure what has happened. The last update I did was on the 15th. I've rebooted a number of times since then and haven't updated/installed any packages. But clearly I must have changed something but for the life of me I can't remember changing any settings video related. Now X does not start. This is what I get now
[Code]...
I am running Wheezy 7.9, I have a Biostar motherboard with integrated Intel graphics (945 chip set), and a Viewsonic va912b 19" LCD monitor. I have recently been having problems with the computer not being able to read the EDID data from my monitor. About half the time the EDID is read okay. So, in order to set the monitor to the desired resolution I have created a shell script to set the resolution after I log in. Knowing that my monitor supports 1152x864 @75hz I used cvt to get the modeline info.
Code:
Select allroot@JohnBoy:/home/john# cvt 1152 864 75
# 1152x864 74.82 Hz (CVT 1.00M3) hsync: 67.71 kHz; pclk: 104.00 MHz
Modeline "1152x864_75.00" 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
Then I wrote this shell script.
Code: Select all#! /bin/sh
#! /etc/init.d/monitor_1152x864x75
#
#add monitor resolution not being found at startup
#data from cvt
xrandr --newmode 1152x864_75.00 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
xrandr --addmode VGA1 1152x864_75.00
exit 0
It works fine, but I see a difference between what cvt gives versus what I see in the xorg log file (when I get a good EDID read). Here is what I see in the xorg log.
Code: Select all[ 17.611] (II) intel(0): Modeline "1152x864"x75.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz e)
Notice that there are some small differences in the horizontal and vertical timings, cvt versus xorg log.
The biggest difference, to me, is that cvt has -hsync and the xorg log shows +hsync. I would assume that the data shown in the xorg log file is based on what was received from the EDID and therefore is what the monitor expects. Is that a correct assumption? And might using -hsync as per the cvt, versus +hsync, affect the monitor operation? Using -hsync does not appear to create any kind of video artifacts (tearing or distortions).
Lots of these in my dmesg, dont like that. Don't think it should be there. Don't know how to get rid of it. What i do know is:
It's intel graphic card related on Ubuntu 9.10 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux On a EEEPC 1000H
A few months ago my monitor broke and began using an old one that does not have EDID.Since then i havent been able to configure my computer with a stable video configuration.I`ve tried a thousand times to edit xorg.conf and i actually got it let me use resolutions higher then 800x600, but when i reboot my computer my usuall setting 1024x768 gets switched back to a lower one - its a pain... my icons get scrambled, the gnome panels, etc.Do I need to edit any other file then xorg.conf?
And another thing I noticed today is that the gnome display manager does not recognise the higher resolution of nvidia-settings. Does it have a seperate settings file?
Apparently you can't get EDID information through a Displayport->DVI adapter. That means that a default install of Lucid (or Natty!) does not recognize the resolutions of any monitor connected with such an adapter.
I'd rather not create an entire multihead xorg.conf just to specify NoDDC. Is there any other way to pass that option to X?
I just installed jessie on a machine that had been running wheezy with no problems. Now I see that a kworker process is hogging nearly 100% of one of the CPUs. I am not sure how to proceed with solving the problem even after doing a number of Google searches.
I'm not sure if this is related, but I am getting the following when I run 'dmesg':

I had problems with the system not reading the monitor EDID and have fixed the problem by adding an override file in xorg.conf.d and all of that seems to be working well (although the system has not failed to read the EDID since I implemented the override. go figure).
The thing that I am wondering about is something I see in the Xorg log file. At the end of the log file, after everything seems to be configured, there are six (6) identical blocks of information regarding the EDID and modeline settings. Is this normal or is X stuck in some kind of loop? Everything is working and I am not waiting an inordinate amount of time to log on, or after. Just curious. Here is the log file.

I have got a very frustrating problem. I am not new to Ubuntu but this time I bit my tongue! Actually it is a problem related to my graphics card "Intel 945GM" , it is a real crap card but it is working fine with Windows XP pro (I use windows just for testing)!
Problem : My monitor DELL ST2310 would not work under DVI mode (only VGA mode is working fine)! I tested with Kubuntu, Ubuntu (several distos), Fedora 13.. Upon booting, I get this error message :
Code:
EDID checksum is invalid
remainder 130
the monitor DVI connection is working perfectly under Windows XP. This means the Intel 945GM cannot read the EDID hexadecimal data transmitted by the monitor through the DVI connection. Yet, System recognizes the graphic card's DVI-D port but set it as disconnected.

I burned a new disk with ubuntu 11.04 image and I managed to boot the live cd using my external monitor, I've installed and went into my monitor settings, it displays my external monitor as unknown and doesn't even detect my laptop screen. Changing the driver being used in my xorg.conf to vesa allows me to boot properly and ubuntu uses my laptop screen (yet it still detects it as an unknown monitor). Installing any nvidia driver and using it breaks my system. Heres an image of the laptop when using the nvidia driver (btw I can still hear the ubuntu sound that plays when its reached the logon prompt).

I have installed a fresh copy of FC14 and when I logged in locally for the first time I was getting the error messages below. Now these same messages are filling up my messages log and it's running non stop in the background. Has anyone seen anything on this error? I have searched through Google looking for help and I'm not finding much.
This box is a simple file/web server with no monitor hooked up and no GUI. I have also included the lspci ouput below if that might help. Really looking for any suggestions or input on how I might stop the error reporting since is filling up my log files quickly.

Before I upgrade to 10.4 It would be nice to find the best solution to this problem. I use a KVM switch that dont pass the EDID info from the screen to the OS. To solve this, that is, to get the correct screen resolution, i need to pass monitor and screen info to the OS at every startup. One way is to ad a script to /etc/gdm/init/default, or in KDE /etc/kde4/kdm/Xsetup.

View 3 Replies View RelatedUsing Debian stable. 64-Bit. I can play videos and music using Totem and VLC. And I can play audio files with audacious and Rhythmbox. And I can play flash in firefox and google-chrome. But, if I open audacious and then play a flash file in Firefox or google-chrome audacious crashes as well as other multimedia players that I have open such as Totem, VLC and/or Ryhthmbox.
Would like to know if you can offer some troubleshooting steps to take so that I can play a flash file in a browser and still play an mp3 file in the audio player without having to kill those processes and restart.
I finally installed Squeeze on my laptop and found out that the XF86Audio multimedia keys do not work.
When I press them, they're correctly identified by xev but they do not produce the desired effect (raise/lower/mute volume, play/pause/stop/prev/next song in media players like Sonata).
Funnily enough though, they do work in Audacious, which has its own plugin to manage XF86Audio media keys.
So it's like the action of pressing these keys is not intercepted by the system and no event is triggered.
I think this might be due to a missing package or configuration but I have no idea where to look...
I want to stream .avi *divx/xvid* (because of the nice compression and quality) online and have all streams accessible through a web based library type thing. Something like Jinzora ( http://en.jinzora.com/ ) is what I am looking for, but it's buggy. I would even be satisfied with a web based library of streams that you click and open with an external program. I have searched a lot for this and the only thing I found that can do this how I want (if it worked right) was jinzora. I don't want to convert to mpeg4 or flv because of size and quality issues.

View 7 Replies View RelatedI am using debian squeeze and did an aptitude upgrade yesterday. Today I've found that VLC won't play any video; the files open and the audio plays, but the video is black. The aptitude log is below.
I note that VLC received a security upgrade a few days ago, but my suspicion is that the source of this problem is more likely to be the upgrade of libavcodec52 from version 4:0.5.2.6 -> 5:0.6.1+svn20101128-0.2. I believe this upgrade came from the debian-multimedia stable repo I have enabled.
Does this sound right, and what could I do to fix my VLC playback? This is new territory for me, and I'm slightly surprised that such an upgrade would come from the stable branch of debian-multimedia (although I know this is not an official source).

Below is the recipe I've used to compile dwm from source on Squeeze
su
apt-get install devscripts debian-keyring
apt-get build-dep dwm
exit
It all seems to work, however debuild gave an error about secret keys. Is this a sensible procedure? What happens in the (probably unlikely) event there is another source patch?I've gone to a tiling window manager as the result of the purchase of a wide screen LCD monitor. I like to have some stuff down the right hand side when running Firefox and OpenOffice in the main panes. Any configuration tricks welcome. Modern screens are the wrong shape!
Just got a pretty fresh install of Debian/XFCE. Both monitors work out of the box on my 8400GS. I was unable to find an option to change it so I can span is as 1 work space instead of having them mirrored.
