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?
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.

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'm trying to install Xorg manually in Squeeze on my IBM X30 Thinkpad with intel graphics (it works in Lenny). I used aptitude and installed "xorg" and "fluxbox", but when I restart my computer I get a blank screen, instead of the console login request that I was expecting. (Note: I did not install any login managers). So exactly what happens is that the screen goes black (just backlight on)during boot process. Once I'm at the black screen doing CTRL+ALT+Backspac, Ctrl+Alt+Del or Ctrl+Alt+F[1-7] will not result in anything.
I tried booting with the single user mode, but same result, so the only way I could acess my log-files was by using a systemrescue-CD. What I find odd about this is that I cant find any configuration files at all. No xorg.conf anywhere in /etc, /etc/X11, nor in /home. I don't even have a /etc/X11/xorg.conf.d folder.Am I expected to write these by myself? And if Xorg is the source of my troubles, why is it starting by itself, without any installed login managers? Xorg not working is one thing, but not even being able to access the console, or log in to my computer makes it rather difficult to search for errors.
I was configuring my visual settings and thinking that my pc could handle the max setting I enabled it. Now I cant see or do anything. Is there a way to reset them???
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 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.
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).
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.
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.
This is my third SLackware install. I installed 10,12, now 13. the Xorgsetup has changed I think, it does not display the screen to choose Horizontal and Vertical settings for the monitor. In addition, how can I set the Refresh rate?
I've been using ubuntu on a new desktop for a couple of months, but i had an old HP that was given to me in my basement. It has 384Mb of ram, and thats because i had a 256Mb stick laying around. I installed debian becuase it is more suited for older hardware (at least from what I've read). It installed fine, but it boots to a blank screen, and pressing ctrl+alt+F2 bring me to the command line. I checked /etc/X11/xorg.conf to change the driver to vesa, to find out my video card isn't even shown. I ran lspci and I found that it says my graphics card is Intel Corporation 82810E DC-133 (CGC) Chipset graphics controller (rev3) In the device section of xorg.conf, it merly says Identifier"Configured Video Device"
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
I'm trying to get my screen resolution set in Mythbuntu 9.10, but there is no xorg.conf on my system! I'm trying to figure out what to do (the xfce tool on mythbuntu doesn't offer the correct resolution, and I'm not even sure what driver I'm using). I've seen other threads saying to run nvidia-setup or somesuch. I assume the appropriate tool in my case would be aticonfig (I saw that elsewhere too) as I'm using an ATI Radeon 9600XT, but that tool says:
I am new to Linux and installed Debian. After the Installation I started Debian and ended in a black screen. I came out there changing to a terminal (ctrl+alt+F1) but I dont know how to get Xorg running. I am using the Mainboard:Gigabyte GA-D510UD without any extras (means just the Mainboard with Ram and an IDE Hdd). here is the Log file from Xorg [URL]... System Information is in the log.
The X server in Debian seems to have a "funny" habit to suddenly start blanking the screen if I don't touch the mouse or the keyboard for a while, although I've used the xset command (xset -dpms s off) in my ~/.xinitrc to tell Xorg specifically NOT to blank the screen. I know how to disable screen blanking in /etc/X11/xorg.conf, but I'd rather not have the xorg.conf file at all.
So, I'd be interested to hear your suggestions about how to disable the Xorg screen blanking without using the xset command or the xorg.conf file. Is there some other file in /etc/X11/ that I could tweak to disable this highly annoying desire of Xorg to insist on blanking my screen after a bit of idle time?
After a install on a old Toshiba today everything looked fine. But when i tried to start Xorg it start but doesn't use my whole screen. It is not a resolution problem it just doesn't use the whole screen. Hopefully this explanation is understandable. On lenny i had the same issue but once i changed the console resolution size in grub everything was fine. Sadly this is not the case with squeeze. I already tried "X -configure" and had a look at the generated xorg.conf (posted below)
[code]....
After that is tried to run the generated xorg.conf but then it just frooze.
I have a Dell E6500 laptop (1280x800 screen), which I frequently dock.The dock as two Dell 1908FP 20" monitors connected by DVI. I can move between the laptop display and the twins by manually changing display configuration in NVIDIA X Server settings, but this is a pain requiring about 15 clicks each time.
I have tried using the "Save to X Configuration File" option in the Nvidia server settings, but this seems to screw everything up. I need to dynamically change between the setups... anyone have advice on getting that done?Can the xorg.conf file be configured to do it?My xorg.conf looks like this:
I have an Asus z9100 laptop with an Intel 855GM integrated graphics chip, which is running Karmic (the purpose of the laptop is to be a MythTV frontend so my understanding is that it needs to run 9.x in order to connect to the MythTV 0.22 backend - I have installed and configured this using the installable Mythbuntu package) and the laptop is subject to this bug which causes random freezes:
[URL]
So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:
nolapic nomodeset
and I have edited xorg.conf so that it makes use of the vesa driver instead of the Intel driver. This results in no freezes and if I wanted to watch Myth on the laptop screen I'd be squared away. However, the laptop has a damaged screen so the point was always to output the signal to an external monitor via its VGA out.
When I attach the external monitor and boot with the setup as described, the external monitor is never detected. But I noticed that if I remove the "nolapic nomodeset" from the kernel boot line, it is detected. However, signal is only output to it during the earliest part of boot (when the Ubuntu logo is in the center of the screen before the full-screen graphic with the animated progress line), after which the external monitor goes black and all the display output goes to the laptop screen. The external monitor power button is still lit up green as if it has been detected and is receiving signal, but it's just a black screen.
get the signal out to the external monitor after the initial part of the boot process, using the vesa driver? Here is the current state of my xorg.conf:
Code: Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection
Just got an HP dv6-2150 laptop. Dual boot with Windows 7 and 9.04 (9.10 will not work but that's a different story). The screen resolution is too low and is set at the highest option available (1024x768 which is a 4:3 aspect ratio). The HP uses the new Intel i3-330m chipset with on-board Intel HD graphics. The system is capable of 1366x768 resolution (16:9) - so how do I get it there? xorg.conf looks real generic - nothing specific to Intel.
When I go to change the Visual Effects settings from Normal to either of the other 2 choices, the screen goes black and nothing happens. Could this be a driver issue? Should I buy a video card instead of using on-board and if so, which ones work the best with Ubuntu?
I had Ubuntu 10.04 running fine. Then I got curious about NVIDIA XServer.
"ATI Technologies Inc RV380 [Radeon X600 (PCIE)]" - Video Card
I opened it up, clicked a settings change, and said OK. It said you need to update your blah blah blah. Then it said blah blah blah doesn't exist. Then it said it would create it for me. Then I said REBOOT!
Now I get a black screen of death.
The only way I can get anything to happen on my monitor that comes from this computer is to boot into the Install Disk and say "TRY UBUNTU".
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.
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'm a relatively new Debian user, having come from Ubuntu. I recently bought a Dell micro-server to function as my Kodi media player. I installed an nVidia GeForce 210 to output to my Pioneer home theatre amplifier. The amp takes all my inputs (eg. Satellite set-top decoder, PS3, Kodi etc) and outputs to the TV. I installed XFCE as my desktop environment so that I could still interact with it via VNC.
Everything is working great except for one exceptionally annoying problem! Every day, I find that I am having to VNC into the desktop, load up nVidia X Settings, and change my screen resolution from Auto to 1920x1080 because it has lost the display configuration and the screen is blank. I presume this happens when the amplifier switches from one input to the next. It doesn't matter if I save the configuration to my X11.conf file or not - it still resets itself.
Before, this setup would run for months without any intervention (Same amplifier + HP microserver + Ubuntu + LXDE + ATI video card), so I'm pretty confident that the issue is either Debian, XFCE, or the nVidia card.
I want to using ubuntu 9.10 karmic koala. In that i want to see the file /etc/X11/xorg.cong file. But i didnt find that file in my distro. So please can anyone tell me how to see that settings and if i want to edit that how to do that?without seeing the format and alues in that file i cant add that file.
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.

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?
