Debian :: Xorg Log File - Six Identical Blocks Of Information Regarding EDID And Modeline Settings

Feb 4, 2016

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.

Ubuntu Multimedia :: NoDDC Without Xorg.conf: No EDID Information Through Displayport/DVI

Apr 23, 2011

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?

Ubuntu Multimedia :: Screen Settings And Xorg Configuration / EDID Trouble

Jan 19, 2010

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?

Debian Hardware :: Wheezy 7.9 - EDID / CVT And Xorg Log

Dec 4, 2015

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).

Ubuntu Multimedia :: How To Add Modeline In Xorg.conf

Sep 1, 2011

I have an apple tv1 running ubuntu hardy. Due to audio video requirements I do not want to upgrade. I am trying to get 1080p24 working my TV. I ran X in verbose mode to ensure that my TV supports 1080p24 and it does. For some reason the X is not able to see the 1920x1080 @ 24Hz mode. I got the required information to add the modeline to my xorg.conf.

My xorg.conf is as follows

Code:

Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0

[CODE]....

When I check the Xorg log file I have the following warning

Code:

(WW) NVIDIA(0): No valid modes for "1920x1080_24"; removing. Is there any way I can append the valid modeline for 1920x1080 @ 24Hz to. I am avoiding using a modified EDID.

Ubuntu Installation :: Network Settings When Cloning To Identical Hardware?

Aug 9, 2010

The company I work for use Ubuntu on the PC's that control the system they manufacture. To simplify and speed up the OS install we use a standard PC (all the same hardware) and install a disk image on each system. The disk image was produced from one of the systems and the network settings were set to use a Static IP

However every time we clone a system the network settings change from the static IP settings to Roaming Mode.

why this happens or if it is possible to have the static IP settings remain after the clone?

Debian Hardware :: Synaptics Touchpad Settings In Xorg Have No Effect

Feb 16, 2010

I suppose this thread has been created over a hundred times in the history of this forum, but yet it seems like I cannot find any solution to it. Nor has the Debian IRC-channel been able to channel the requiered information to me so I'm comming here as sort of a last resort.So my issue is that, as described in the topic, none of the settings I set in /etc/X11/xorg.conf have any effect on the touchpad. Other settings in xorg.conf such as color-depth for the screen and driver for the graphics card have effect but not the touchpad section. And if I make a syntax-error in the xorg.conf file X doesn't want to start, which is a clear indication that it's using that config file.

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

Debian :: Kworker Hogging CPU On New Jessie Install - EDID Checksum Is Invalid

May 16, 2015

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.

Debian Configuration :: Ifconfig Wasn't Displaying The Same Information That Resides In /etc/network/interfaces File

Aug 14, 2011

i recently started sockets programming. In the process i began to look for relevant network information about my computer and realized that ifconfig wasn't displaying the same information that resides in my /etc/network/interfaces file. On the interfaces file my IP address is 192.168.1.109 for interface eth0 but ifconfig displays 192.168.1.101. I was under the impression that ifconfig got its information from the interfaces file but clearly doesn't. I tried re configuring the device with ifconfig and then disabling and re enabling the device with ifdown and ifup so that the device updated its information but it didn't.

Ubuntu :: Xorg DPI Settings Not Being Used?

Jan 25, 2010

First off my monitor is a 720p plasma, native resolution is 1024x768 and yes it's 16:9. Video is onboard ATI 4200 (AMD780G). and I've tried the fglrx, ati, and radeon drivers. So I would like my dpi settings to reflect that the pixels are longer horizontally (that there are less of them)

So i've been changing DisplaySize, and tweaking X with other options like [Option "NoDDC" "true"] etc. Nothing seems to change the display.

So then I check xdpyinfo and it reports what I have in X and it's what i've configured.. So I try wiping out X and seeing what it picks up and what do you know, it's auto-detecting everything fine.

Code:
screen #0:
dimensions: 1024x768 pixels (160x90 millimeters)
resolution: 53x95 dots per inch

So the problem, it's not using these settings. I can change the DisplaySize to 1000 10 or 10 1000 and the display does not change, but xdpyinfo does correctly report what I've entered.

Debian :: Swapping Hard-drives With Identical Motherboards

Jul 7, 2011

I have two servers (A and B) which are identical. My idea was to have a software RAID 1 with both of them running and if server A craps out I wanted to swap the hard drives from server B into server A. When I tried to test this idea the network driver doesn't seem to want to cooperate. ifconfig gives nothing and I can't figure out why. From googling I've read that a network card has a unique ID on it (I'm assuming their talking about the MAC address) and is used in some config files which is why swapping hard drives gives two different MAC addresses and confuses the system. If that is so would anyone know exactly what config files the mac address is stored/used in? That way I can make a backup of those files and swap those out if I ever need to swap out the hard drives.

Debian Multimedia :: Dual Monitor Setup - Two Identical Outputs

Sep 2, 2015

Just installed Debian 8, coming from Ubuntu12, it seems I cannot get my dual monitors to work as it should.

I want two monitors side by side, currently I have two identical outputs. I looked around a bit and register two possible problems.

root@bigcem101-debian:/home/bigcem101# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm

1024x768 0.00*
800x600 0.00
640x480 0.00
720x400 0.00

Hence, problem 1: it is as if there is only one monitor detected. Then I tried to look for Xorg.conf ..... and: problem 2 xorg.conf is not there. This seems to be normal but when I installed my Ubuntu years ago it was still there and one could manually set things. There must be something new I am missing.

Card:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV670 [Radeon HD 3690/3850]

It seems I have both ati and radeon installed.

root@bigcem101-debian:/home/bigcem101# X -configure
(EE)
Fatal server error:
(EE) Server is already active for display 0

I am clueless.

Ubuntu :: X Doesn't Read Settings From Xorg.conf?

Jun 16, 2011

I'm running Kubuntu 11.04 on a laptop with dual monitor setup. I have Nvidia graphics card and I've successfully configured TwinView for the monitors. However, after saving the settings to xorg.conf (using the nvidia-settings application) X should use both monitors after boot, but only the main monitor is used. I first thought that X didn't read xorg.conf at all, but when I put some illegal statements into the file X wouldn't start and gave an error about the illegal statements. It is thus clear that X does read the file, but it just doesn't seem to use the settings in it.

Debian Configuration :: Grub Config For Dual Boot (Identical But Independent)

Jan 3, 2016

I have a Jessie with grub2. I've bought ssd and copied root partition onto it. I've also installed grub on this disc. I would like to have dual boot:

- First option: old root booted from hdd
- second option: boot from copied ssd and use root from it.

So i would have two identical but independent configurations.

Both disc has different uids (changed after cloning).

I had a hope that i will change fstab to mount root partition from ssd, but it doesn't work. I need to change grub configuration, but how to add new position?

There is also problem that bios doesn't allow me to choose disc to boot from. So i would rather prefer to change grub configuration for dual boot from different disc.

Ubuntu Multimedia :: Can't Detect TV In NVidia-settings With Xorg-config

Feb 14, 2010

I have connected my computer to my LCD-TV (HDMI-cable) to enjoy my movies and such, on a big screen. I have nVidia GeForce 7050 so in nvidia-settings I've been using the TwinView configuration which allows me to see both the monitor and the TV.

There was a bit of trouble-shooting but it worked just fine until yesterday when I changed my monitor to a new one and on the way probably messed up in nvidia-settings. I thought it would be easy to fix it but the configuration (in nvidia-settings) is stuck on "separete x-screen" and doesn't allow any changes at all. When I hit the "Detect display" nothing happens although I have the TV connected!

Maybe my xorg.config could tell somebody what is wrong. I've been messing around with the file and made lots of changes acc to different advices but I really don't understand the options and settings so I'm afraid I'll soon do something inreperable.

Ubuntu :: Modeline For Vizio 32" TV?

Sep 10, 2010

I have an Nvidia GeForce 6150 integrated video card, and my TV is a Vizio VW32L. I installed the latest recommended driver from the Hardware Drivers. When I open the utility, I can select 1360x768, which is pretty close I thought. I selected this and hit apply, but it cuts off both the right and left side of the screen. For example, I can't see the Applications in the upper left corner. I went in to the TV menu and auto-adjusted, but it still cuts off both sides. I looked around the forums a bit and it sounds like I have to create a modeline. This is from my manual:
1366x768
60Hz
47.55 H.Freq (kHz)
59.81 V.Freq (Hz)
Positive H.Sync
Positive V.Sync
85.50 Pixel Freq (MHz)
I typed this in on http://xtiming.sourceforge.net/cgi-bin/xtiming.pl and got the modeline:Modeline "1360x768@60" 84.50 1360 1392 1712 1744 768 783 791 807

Can anybody verify these settings? Or am I going to screw up my TV? Also, I'm pretty new at this. Where in the xorg.conf file do I put this information?

I was looking at other threads and I think I have to add +HSync +Vsync to the end, because my manual says they're both positive, right?

Ubuntu :: Change File Permission Settings To Force All Documents To Inherit Parent Document Settings?

Aug 21, 2011

i have a computer with 3 users on it, and a folder using samba that everyone on the network has access to. Lets say that, the folder is stored in /etc/sharedfolder. What happens is, when user1 puts a folder in it, then logs off, user 2 attempts to modify it and fails, because permission is set to 755, and they are not in the same group. (even if they were, it should still need to be 775) Anyway, my current solution is, every 5 minutes a crontab changes permission like so: chmod 777 -R /etc/sharedfiles && chown useradmin:superadmin -R /etc/sharedfiles Which works, but seeing as there is getting close to a gig in there, this is a bad solution, as it eats up the computers resources. Solutions that i think might work:

1) create a script that only changes permissions that need be changed.
2) change file permission settings to force all documents to inherit parent document settings
