Debian Multimedia :: Wheezy - Xorg 3 Monitors And Y-splitter
Feb 26, 2015
I am pretty new to using Linux, I am currently trying to configure 3 monitor's with Xorg in Debian Wheezy. I have 2 video cards in the PC and one has a Dell Y-splitter to connect 2 monitors. 2 monitors are 1920x1080 resolution and the other is 1280x1024.

I attempted to write my own xorg.conf file, but that resulted in the machine booting to single user mode and the xorg startx error log said it could not find any devices.
When I used the xorg.conf.new generated by the "xorg -configure" command, I was able to get it to display as 3 independent screens, but there was overlap on the screens. I.E. if you moved the mouse to the right side of one monitor, it would show on the left side of another screen at the same time.
automatically generated xorg.conf:
Code: Select allSection "ServerLayout"
    Identifier   "X.org Configured"
    Screen   0 "Screen0" 0 0
    Screen   1 "Screen1" RightOf "Screen0"
    Screen   2 "Screen2" RightOf "Screen1"

My hp does not want to start X for some reason. I have so many errors. I made an account to just see this problem be fixed. Now when I type "startx" I get back, "bash: /usr/bin/startx no such file in directory". I have to use GRUB due to the fact I forgot my login. Although, I do remember my password.

I experienced this problem on Friday but didn't have time to write a warning.A couple of days ago, xserver-xorg-core 2:1.10.2-1+b1 reached Testing before a corresponding dependency (recommendation), thus breaking the hardware acceleration. The issue is (better) described here (1) by a developer.A possible solution is to keep (2) the previous version (2:1.10.2-1) or, if you already installed the faulty one, to grab the former version from Debian Snapshots (3) and downgrade the package.Because the error was a simple path change, one could also keep the new version of xserver-xorg-core and link the DRI Mesa modules to the directories that are inspected now (as described here [4]).The issue has already been addressed (5) and a new version should appear in Testing shortly.[URL]

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"Â 104.00Â 1152 1224 1344 1536Â 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_75.00Â 104.00Â 1152 1224 1344 1536Â 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[Â Â 17.611] (II) intel(0): Modeline "1152x864"x75.0Â 108.00Â 1152 1216 1344 1600Â 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).

Something within the group of updates which I installed last week (April 6 to 10 or so) has impaired the functionality of my mouse's scroll wheel. It will no longer scroll pages on Iceweasel, Midori, some PDF readers, PCManFM, and others. The "up arrow" and "down arrow" seem also to have been compromised. I suspect the culprit might be libx11. This is an amd64 system with the nvidia video driver.

If you do, please let me know what sound card you're using. I'm beginning to think its the driver. All kinds of weirdness in early bootspace and also alsactl init fails with a missing init directory for the device.
I'm on a Creative Labs Soundblaster Audigy SE and it's completely non-functional. I've seen bugs reported with the audigy LS but never the SE.

I use ffmpeg to covert video files for the net.
Code: Select allffmpeg -i infile -vcodec libx264 -vpre ipod640 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s res.mp4
which works good. I was wondering if I could use larger resolution presets, but
find /usr -iname '*.ffpreset' only gives
#/usr/share/ffmpeg/libvpx-360p.ffpreset
#/usr/share/ffmpeg/libvpx-1080p.ffpreset
#/usr/share/ffmpeg/libx264-ipod320.ffpreset
#/usr/share/ffmpeg/libvpx-1080p50_60.ffpreset
#/usr/share/ffmpeg/libx264-ipod640.ffpreset
#/usr/share/ffmpeg/libvpx-720p50_60.ffpreset
#/usr/share/ffmpeg/libvpx-720p.ffpreset
with only 2 presets for libx264.
I installed ffmpeg from deb-multimedia. Is there a package which provides further preset files? There should be e.g. hq, max etc..

So the other day I installed Debian Wheezy on my Sun Blade 150. While the OS is installed fine, all the webkit based browsers continuously crash after a few pages. So, I tried to download IceWeasel since it wasn't installed when I tried installing Debain off the DVD. The only problem is, it won't install as the Xulrunner version it requests is xulrunner-24.0_24.5.0esr-1~deb7u1_sparc, however the only version available on the repositories is newer. Is there any way to get the older xulrunner version, or is there going to be a fix for IceWeasel soon on Sparc?

I have some very strange issues with my tripple monitor setup on debian wheezy. I have acer aspire V3 laptop with i915 Intel (Intel® HD Graphics 4000) as part of i3 and nvidia GT 740M which I never managed to get working with or without optimus to any degree whatsoever. What I want is a reliably working triple monitro setup. I have 2 additional DELL u2412m monitors which I did manage to get to work on few occasions by more or less randomly turning stuff on and off via lxrand and KDE systemsettings (so I do knwo for a fact that tripple monitor setup works). Arandr doesn't work, and executing xrandr from cmd doesn't work. I can relatively easily get the 2 monitors to mirror each other, but to get them to work separately is extremy difficult. It's always the same error but the well known crt. For example:
xrandr --output VGA1 --mode 1920x1200 --pos 3840x0 --rotate normal
xrandr: Configure crtc 2 failed
xrandr --output VGA1 --mode 1920x1200 --rotate normal --right-of LVDS1
xrandr: Configure crtc 2 failed
When it did work I copied arandrs script in hopes it would work, but it doesn't. Obviously, here is the issue that the crtc can not be configured so if somoen could tell me why and how to get the damn thign to use a specific crtc it would be awesome. Also, I noticed that when I hit "identify monitors" in KDE systemtools, it would say VGA HDMI for both VGA and HDMI outputs.
Here is xrandr output from when it worked:
Code: Select allScreen 0: minimum 320 x 200, current 5760 x 1200, maximum 8192 x 8192
LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm

    Timestamp: 143521
    Subpixel:  horizontal rgb
    Gamma:   1.0:1.0:1.0
    Brightness: 1.0

Here is now:
Code: Select allScreen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192
LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm

i have an installation of wheezy 7.8 i think. i was facing difficulties in read of matroska video. therefore have decided to installer gstreamer1.0 wich should be resolve my problem. i have added the backports repository in apt sources list. after an apt-get update i launch apt-get install gstreamer1.0 . i have noticed it have starting downloading more file than it needs i concluded that it was a upgrade or something like because the kernel was also updated. after the the packet downloading it has started the installation with some errors related to LOCALE LCC. it has stopped and restarted some services wich is normal. i have closed all others apps and restarted. Here start the hell. after the restart i have passed the kde login screen and after BLACK SCREEN with mouse working.
Alt+F2 don't open the krunner
What i have tried? i have rename the /home/jefcolbi/.cache and back it again, rename /home/jefcolbi/.kde and back it again. next i have tried to check the Xorg config file. i created a new one with X -configure, modified it to feet my system configuration this does not resolve the problem but add another the keyboard is not working in graphical mode.
My system configuration:
Toshiba laptop Satellite Pro L300
Dual core
3gb Ram
graphic card:Mobile Intel(R) GMA 4500MHD
sound card: Intel HD Audio
debian whezzy 7.8 with KDE
Note: everything was working fine before trying to install gstreamer1.O from backports repository

The problem: backlight is in maximum state and I can not change it.
There are a tons of advices like this:
1 - Open terminal (as a superuser) and type: gksudo gedit /etc/default/grub
2 - In the text file that opens, find the line which says GRUB_CMDLINE_LINUX="" and, inbetween the "", insert the words "acpi_backlight=vendor" (the line will be as follows: GRUB_CMDLINE_LINUX="acpi_backlight=vendor"), save and close the file.
3 - Back again in the terminal session, type: sudo update-grub
4 - Reboot.
It does not work...

I'm having all sorts of problems after doing my first update (#1. safe-upgrade, #2. full-upgrade) in over a month.
Anything from no Nvidia linux-headers being found to any VT not working. After completely removing all of the previously tried Nvidia presence on my PC, is there a safe way for me to install the non-free drivers?

I have Xfce installed on wheezy, and I was planning on installing some KDE components for kicks. When I tried to install kdebase-workspace I got this error from aptitude The following NEW packages will be installed:
[Code]...
The following packages are RECOMMENDED but will NOT be installed: kinfocenter plasma-scriptengines policykit-1-gnome polkit-kde-1 upower 0 packages upgraded, 30 newly installed, 0 to remove and 49 not upgraded.
Need to get 78.5 MB of archives. After unpacking 137 MB will be used. The following packages have unmet dependencies: xfce4-notifyd: Conflicts: notification-daemon but it is not going to be installed.
If it's not going to be installed, then where is the conflict? I've seen "Depends: X but it is not going to be installed", which makes sense. The only solutions are to remove xfce4-notifyd or to keep most of the KDE stuff uninstalled. apt-get also wants to remove xfce4-notifyd. Edit: Ok, it looks like both plasma-widgets-workspace and xfce4-notifyd provide notification-daemon, but I still don't understand why the aptitude error doesn't tell me that xfce4-notifyd conflicts with plasma-widgets-workspace instead of notification-daemon.

There is a folder in my home titled 'gtk-3.0,' which continues to reappear even after I have deleted it. The reappearance of the folder seems to occur after using lxappearance to change the themes. I will not be participating in the headaches of the switch from gtk2 to gtk3, just as I did not participate in the headaches of the switch from KDE 3 to 4. So the following are my questions;1. Is it possible to permanently delete the gtk-3.0 folder so that it can not ever reappear in my home? (And why is it appearing there anyway? Shouldn't it be hidden with a dot?)2. If I can not prevent this folder from appearing in my home, is there a setting I can use in Wheezy to block gtk3 libs and apps from installation? Presently, the only gtk3 lib or app shown by aptitude search is libcanberra-gtk3-0, but I can't remove it due to notification-daemon dependencies.3. If I switch from all gtk2 apps to all KDE apps will that solve the problem of gtk3 placing a completely unnecessary folder in my home?

fresh install of 11.04 on a built system (frankenstein leftovers), 2.something ghz, 1gb ram, a host of drives, and a 64mb nvidia mx440 with svideo out. Boots up, looks pretty, something about unity not finding 3d graphics (fine, i don't really want it, just more fancy gui crap to suck cpu cycles) and runs fairly well. so I think, cool, svideo out, old 52" rear projection....HTPCish. "Lemme get this thing hooked up to the tv, what a great idea" So, I start looking around and find all kinds of wrong posts about not Natty, and not my video card, and I try this n that,and it doesn't work. I'm all about reading the forums, but I can't find the right info for my sitiation, and I'm overwhelmed/irritated.
Long story short, I added some repository ppg something, and then dl'd and installed the "nvidia-current" driver. After a reboot, I fire up the nvidia gui, and it tells me I have no xorg.conf and to run a particular command in terminal to make one. So I did it. and after another reboot, my system just hangs at "ubuntu" with the four (five?) dots. Reboot, recovery, something something something, safe graphics, backup your xorg.conf? yes. reboot and all is ok now. still no nvidia support. Now I'm reading the internet machine about the xorg.conf being old school, and how I have to make a monitor.conf file with config settings. only problem is it tells me to go to x11/xorg.conf.d/whatever. I have no xorg.conf.d directory. So what's the deal? How in the hell do I get the nvidia driver installed (I think I got that), configured (I have no clue), and running (yeah, I just saw a flying pig)?

I am having some real problems with my dual monitor setup in Centos 5.6.I am trying to run 2 individual monitors like span say the whole desktop over 2 monitors say, using the Admin>Display (I think it's that menu, sorry working from MS Windows at the moment).But everytime I set them up perfectly, every time as it requests you do reboot your computer once the changes have been comitted (written to presumably the xorg config file), the whole Window X Server? it crashes.
Any suggestions as to what to do? I am using an Nvidia Gefore 9600 GSO 768Mb RAM graphics card on it, using one DVI monitor and then an old CRT, but surely it should be the software or even the drivers that are causing the problem.I mean I could just put up with having one monitor but it really bugs me, as I prefer to have one screen for my research and one screen for my production work so to speak.Also I am running an AMD processor +4400 to be exact

I have the following situation:
- Intel HD 4600 and 2 Full-HD monitors (Dell IPS, same model)
- left DisplayPort, right DVI
- Debian stretch with Linux 4.4.0-1-amd64
- XServer X11R7.7 and Cinnamon 2.8.7
… and the following problem:
When I restart the system or login after Standby, usually (not always, but often) some strange green and red pixels appear on the monitor which is connected via DVI. I can remove them by changing the display settings and restoring the extended mode again. However, most of the time the XServer crashes by trying to enable or restore the dual monitor mode (although I’m still able to start a new instance of X from another tty). The XServer also crashes every time I try to enable the extended mode from another situation.
I’ve already tried the following:
- connecting both monitors via DP (no pixes, but also crashes)
- swapping the monitors and using different cables, assuming a hardware problem first (no change)
- VGA instead DVI (works, but inelegant).
- blacklisting i915 or using the xforcevesa boot option (neither of them works, i915 starts though)
- using the nomodeset boot option (detects only one monitor and produces a fallback in software rendering mode)

I just installed wheezy and upgraded to jessie. I had previously gotten sound working in wheezy by installing the flashplugin-nonfree and flashplugin-nonfree-extrasound packages, after configuring my headset in system settings. However, now I can't get sound to play in firefox. I've installed flashplugin-nonfree, flashplugin-nonfree-extrasound, and pulseaudio, still without luck. The volume is turned all the way up in alsamixer, sound tests play fine, and I can play music in VLC without any problems. This leads me to believe it's not a problem with drivers, but with some package I'm missing that will allow firefox to play sound. Sound wasn't working in the default video player either, before I installed the flash plugin. Is there something I'm missing?
Also, sound doesn't play on Konqueror either (KDE browser), which seems to indicate it's a problem with flash and not with firefox itself. After removing the flash plugin and installing pepperflashplugin-nonfree to ensure the pepper plugin was used instead of flash, sound still would not play in chromium, so I reinstalled the flash plugin and still don't have sound in any browser.

I recently installed Debian 8 (Jessie) with the default desktop environment (Gnome), and I use a dual monitor setup. Everything works absolutely fine beyond the fact that when I switch between desktops in the dash (Activities menu?), only the windows on my primary monitor switch, and the ones on my secondary stay the same.
