Recently i've installed 10.10 and have a problem with flickering screen on VGA. I have 64-bit release, ge force 210, nvidia propietary drivers and two monitors:
No matter which monitor is attached to VGA, it flickers randomly every couple of minutes. Sometimes it flickers when i use mouse or keyboard, but sometimes it flickers by itself.
I'm running the latest versions of openSUSE and KDE with latest updates installed. I have an nVidia GTS 250 video card with two monitors hooked up. Initially SUSE recognized my second monitor just fine. However, after installing nVidia's own driver (to quiet the loud noise of the card's fan on high) following these instructions, my monitor is only usable after I go into the nVidia X Server Settings (from terminal, as root: "nvidia-settings") and configure it to TwinView.
All is well and good (I can move windows over to monitor 2), except that monitor 2 has no wallpaper (I'm new to KDE, does this mean that monitor has no desktop activity?) and the X Server configuration is not persistent. When I reboot I have to change the X Server settings back to get monitor 2 recognized again.
I tried looking for the X Server configuration file (xorg.conf, right?), in order to replace it with the edited version, but could not find it.
I have a dual monitor setup (Twinview), both monitors are connected to my 1xNvidia MSI NX8600GT card...I've been using a 21.6inch HannsG HG216D (herein referred to as HG216D) monitor as my LEFT monitor, and a Dell 1905fp (herein referred to as 1905fp) as my RIGHT monitor.
I recently got rid of the 19inch 1905fp Dell monitor and moved my HG216D to the RIGHT and now I have a new 23inch DELL S2309W (herein referred to as S2309W) on the left. The new S2309W is connected to my computer via DVI cable and is configured Perfectly at it's native 1920x1080 resolution.
However I can't for the life of me get my HG216D back to it's native 1680x1050. The HG216D is connected via VGA cable that is also routed thru a KVM, I realize this means that this monitor can't/won't be auto-configured. However I should be allowed to set it manually right?...
Code:
Won't let me select 1680x1050 for the HG216D resolution, it will only let me select 1440x900 MAX, there is no option for 1680x1050, (See attached: screenshot)
I've tried to manually edit my /etc/X11/xorg.conf, but after hours on end messing with it, I give UP...
Here is my current xorg.conf:
Code:
I am just not sure what I need to change and how to get the second xorg.conf to play nice via a VGA connection?
I'm trying to use an external monitor to watch movies on my linux box (kubuntu maverick) but it results always out of sync. TV-out refresh rate is locked as you can see on the image i've attached right here. This is the output of the nvidia-settings query about the variable RefreshRate:
Code: Attribute 'RefreshRate' (DeepBlue:0.0; display device: CRT-0): 60.02 Hz. 'RefreshRate' is an integer attribute. 'RefreshRate' is a read-only attribute. 'RefreshRate' is display device specific.
- Ubuntu 9.10 - Ubuntu 10.04 (beta)Everything was working fine up until a few days ago.
But then... The first problem I noticed was that the Grub screen was flickering ("Auto adjust in progress" came up on the monitor). It wasn't enough to make selecting an option impossible, it's just never done that before. The big problem, though, came when I tried to boot up Ubuntu 9.10 (which I've had on my computer for ages). The Ubuntu logo comes up, but then nothing happens for about a minute, followed by the following error message:
Gave up waiting for root device - Missing modules (cat /pro/modules; ls /dev) LERT! /dev/disk/byuuid/4f743ef0-7a38-481e-613e-ceee3a70ba14 does not exist. Dropping to shell! The only thing I can do then is physically reboot the computer. This happens if I try either Recovery Mode or using the previous kernal as well. Both Vista and Ubuntu 10.04 (beta) continue to work without problem.
Is it possible to run TwinView with more than 2 monitors.When I try, it seems to recognize the 3rd monitor, but will allow allow them to be configured as separate X screens.
I have a GeForce 7200GS graphics card which I've been running in TwinView mode driving 2 IIyama E431S monitors.
I wish to move up to 3 monitors and acquired a USB to VGA adapter but can't get the new monitor to work. I have followed this [URL] and modified the xorg.conf. See below:
Code: # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeister@builder63) Tue Nov 4 14:07:17 PST 2008 # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildd@palmer) Mon Nov 3 08:46:46 UTC 2008
I have connected my TV (and my regular screen) to my Ubuntu 9.10. I use TwinView, and that works just fine. I have also installed Moovida (I love that program). And I would like my PC to open Moovida on startup, but I need it to be on the TV screen.
I have no idea what to do to get Twinview to work. I had found a bit of code to paste into the xorg.conf file but after I pasted it in and restarted my computer, but it wouldn't boot up. Whenever I open up the "Monitors" dialog under System>Preferences, it doesn't even see that the second monitor is there! It doesn't matter if I go to the default tool or if I go to nVidia's tool. On the nVidia tool, under X "Server Display Configuration", there is a button "Configure...", when I press it, it asks "How should this display be configured?". The options "Twinview" and "Disabled" are both unselectable and the only one that I can select is "Separate X Screen". It's almost like my computer doesn't know that I have a second monitor plug.
I recently installed Ubuntu 10.10 (32bit) on an HP compaq nc6400 laptop (internal display is 1280x800, graphics card is an Intel Mobile 945GM/GMS, 943/940GML Express) which I am using in three situations: In my office: external monitor (1280x1024), laptop in docking station with lid closed At home/on travel: as it is, without any external monitor When giving lectures: with projector (1024x786), lid open, same output on projector and internal display As you see, I either want one output device only or both showing the same output. Additionally, I want to run compiz. My problem is that, whenever I (1) connect an external display or (2) when I press the Fn+F4 key to change displays or (3) sometimes even when I open/close the laptop's lid, the system at some point switches to TwinView which seems not to work with compiz on my system. The effect is that compiz is deactivated. When I want to have it back, I have to open the appearance settings and change to extra visual effects again. Unfortunately, that reverts compiz to default settings and I have to adjust my compiz settings again. note that compiz works properly in all three situations I listed above. The problem is "only" that, at some point, it switches to TwinView.
Is there a way to tell X or compiz NEVER TO CHANGE TO TWINVIEW?
I am having issues maximizing windows/applications on triple monitor setup. I would like to maximize wine, folder explorer, media players, and etc to one screen, instead of across both, which it is currently doing that. Using Separate X [xinerama] + twinview, but I have also tried without xinerama + twinview. When maximizing applications and such, it will only maximizes across both of the monitors in the twinview setup, not the separate X on the left. The separate x has maximizing working to that one screen. I have tried to add xorg tweets, but that's not working, and they are currently in my xorg post below. I had maximizing to one screen working perfectly with dual monitor setup. :S And, I am currently getting an error about " Xlib: extension "RANDR" missing on display ":0.0""
The following Xorgs show the differences, I guess if there is one between maximizing correctly to one screen.
Triple Monitor setup, maximizing across both twinview monitors, not preferred:

Im running a dual monitor setup in gnome, with the closed nvidia drivers in twinview mode. most of the times i want to be able to maximize windows to a single monitor (this is the default behavior in 10.04 lucid i believe), but sometimes i want to span a window on both screens. compiz doesn't allow windows to resized past screenborders, and gdevilspie wasn't able to get past this.
After a lot of googling and toying around i came up with the following sollution, i'm posting it here so other people can enjoy it as well (and i'll be able to find it again after my next install).
I made a script to switch between the streched mode and the doublescreen mode to use it, you'll have to stop the autodetection of the outputs in compiz. this option is found in compiz config settings manager under general settings > display settings or though the gconf-editor in /apps/compiz/general/screen0/options/detect_outputs
This script switches between the two modes, but you need to edit the resolutions of your monitors! (i have a double 1280x1024 setup)
Code:
My way of using this: 1. use the script to switch to the span mode 2. start photo/video edit software 3. work 4. close the software 5. use the script to switch back
i have some issues running twinview through my laptop and an additional monitor. i currently have the nvidia settings such that the monitor is the primary screen. however, whenever i click full screen in videos or another application, it maximizes in my laptop screen. also - when i maximize videos videos, the screen fills up, but the actual video size doesn't tend to increase (it doesn't stretch to fit). is this an adobe problem? ubuntu 10.04, nvidia driver v195, dell latitude d630 laptop.
I have 2 nvidia graphics cards and 3 monitors. One graphicss card is an nvidia 460 and the second one is an nvidia 8400 GS. I'm on Ubuntu lucid 64 bit gnome desktop. I use the nvidia drivers . 2 monitors are connected to the 460 card setup as twinview the last monitor is connected to the 8400 GS set as a separate xscreen.
When I now maximize a window on the 2 monitors which are set as twin view it expands this window gets stretched over both screens. I would like to know how I can set it so that an maximized window get only expands on the current screen in twinview so that I can still move windows from 1 screen to another.
I have 32-bit Windows XP and Centos 5.5 x86_64 on my dual-boot PC, equipped with two generic LCD monitors, Dell (primary) and HP (secondary). I have been running dual screen displays without any problem when running Windows, however no luck getting them to work when I boot up with my newly installed Centos 5.5
In both Gnome and KDE both monitors light up, but secondary monitor (HP) is just a clone of the primary. I have tried setting "Dual Head" in the Display adminitrator but the resulting xorg.conf causes a "Entity is already in use" error and crashes. I have also tried just adding Option "TwinView" "on" but it does nothing. (Are "Dual Head" and "Twin View" exactly the same concept?)
What I am doing wrong? I checked the FAQ and did not find any similar problems being discussed.
Below is my getinfo.sh driver info
== BEGIN uname -rmi == 2.6.18-194.3.1.el5.centos.plusxen x86_64 x86_64 == END uname -rmi == == BEGIN rpm -q centos-release ==
I have a panasonic 50" and a samsung 23" both of which are 1080p displays. I have twinview setup so that the samsung is my main and the panasonic plasma is my secondary. For some reason every time I open a windows of lets say mozilla and it was maximized prior to closing before, it will "jump" (briefly display on the samsung monitor for a split second and then automatically move to the plasma) from my main display to the secondary panasonic plasma. If mozilla was minimized before closing prior and I reopen it will open to the samsung in the state it was in on the prior close (aka minimized), which is fine. Only when it was maximized prior does it "jump" to my secondary display.
How can I correct this issue? I would like to have programs open (and stay) in the display they were launched in whether it is the plasma or the samsung.

I'm running Ubuntu 11.04, using an nVidia graphics card. I have my TV hooked up to my computer and acting as a second monitor, using the Twinview option with the gpu. My monitor is set as the primary display, with the TV as secondary.
The problem I'm having is that when I turn my computer on, the main display is black, and all the load up information is output to the second display. Then, when I get to the log in screen, it is also on the second display.
I am posting this to see if anyone else has had an issue with Vmware Workstation 7.1 using unity mode with a Linux Host. The issue I am having is when I try to move a window from my virtual machine in unity mode the screen crashes and then disappears. Everything seems to work while not in unity mode. I have tried various thing like disabling 3d mode in VMware, disabling various KDE effects. I only have these problems with a dual monitor setup, if I switch to a single monitor everything works just fine.
I don't know if this has been asked already, but I cant seem to find it anywhere. I have a gateway, p 7915u with an nvidia 260gtx graphics card. im trying to install ubuntu 9.10 64-bit on it but the screen keeps flickering before I can even install it or try without change.
Whenever i close and then open the lid of my Compaq nc6220 laptop the screen will flicker when actions are made like moving the mouse, opening a program or typing. This is a known problem for the Intel 915 card and the solution is to disable the RANDR process. The thing is i cannot get to the service managaer and the RANDR doesnt come up in BUM which i installed. Does anyone know how to disable RANDR or any other solutions to this very annoying problem?
I had 10.10 installed and decided to chance it by upgrading to the Alpha release 11.04.Graphic card is ATI Sapphire X1550 I think (512MB).Apart from trying to get used to the buggy interface (to be expected from the alpha), the screen keeps blinking, goes black for a second every 30 seconds.
When I first boot up it gets to the checking sensors, then freezes and the screen flickers all the time. I have to do a hard shutdown then when I turn the computer back on everything works normally in fact the boot time is greatly reduced! And so far the system has worked fine after the 2nd boot.Anyone had anything similar?
I just installed Mythbuntu on my old laptop (lenovo with on board graphics card). I have now the problem that when I connect the TV out to my TV the picture is flickering. It looks like the image is sometimes jumping to the left or right for a fraction of a second. This usually happens when the image is not still, ie I scroll the menue or a movie is playing. I already tried different display settings but that didn't help.
I am using Natty and its favoring me with too much of screen and cpu overloading problems.After some usage with movies or browsing, it gets a distortion and whole horizontal lines appear on the screen like a 8BIT distorted Video game. The background actually runs good, since i tried playing mp3 and got the error after wards. After distortion, the windows start flicker and changing. Is there any way to stop this?Second thing,The cpu easily becomes full while mounting drives or surfing itself.
I downloaded the 9.10 from the Ubuntu website (not as torrent, but as direct download) and I burnt the ISO image in a CD. I intruduced the CD in the computer where I want to install Ubuntu and I rebooted it. Then the Ubuntu install-try menu appeared. I chose "try" and appeared a white ubuntu logo fading in and out, and then some text that was like the boot up of Ubuntu. In that point, the screen starts flickering every second, and when I push the power-off button of my computer it stops flickering and says something like "you pressed power off - please remove the CD and close the tray", and then the computer shuts down.
The same happens when I choose Install. At the point it appears a progress number (0%) of the file system, the screen starts flickering and the progress it seems it stops, or at less it's extremely slow.My computer it's a bit old but I think that's not the problem. It's a Pentium IV at 3'40Ghz, 1GB of RAM and what seems to have the problem, a Nvidia Quadro 256MB graphics card (I don't know the exact model but if you need it I can find it).
I did a fresh install of Ubuntu Studio 11.04 on a machine with Vista previously installed. The computer also came with a Personal Media Drive (movable harddisk) of 500GB. The only modification to the HW conf is that I recently added a harddisk of 2 TB that I wanted to install Ubuntu on. (I.e. in total 4 harddisks on the scsi slots)I ran the install cd that I burnt form the iso and I chose the option to manually partition the disks, and I only partitioned the new Harddisk. The installer chose to make some partitions: grub as the boot loader, one ext4 partition of 2 TB and 3.5 GB swap space (and some kb of waste space).
The install cd was readable and the tests that could be performed on the install cd itself and on memory terminated ok, and install seemed to have worked fine. It also discovered the Vista / ntfs partitions. I thought the install would work ok since I had made the new disk the 1st to boot in the HDD boot priority in BIOS setup.
When I rebooted after install I got a blank screen. I then tried with making the Vista HDD the 1st to boot in BIOS, and then I got the GRUB screen with two options for ubuntu two for mem tests and two for the Vista partitions.I found it strange that GRUB would take over, since the grub partition should be on the new lower prioritized HDD in the boot order.When I run the first Vista option everything works. Vista boots. However, when trying to get it to boot either of the ubuntu options I get a flickering screen, in the normal ubuntu boot a white one where the upper third of the screen is more steadily lit up whereas the lower 2/3 is flickering. When booting with failsafe option the color is red/pink instead, but with the same flickering.
I've just installed a fresh Ubuntu 9.10 (I'm using Windows 7), after completing the installation, may laptop rebooted but following the white icon of Ubuntu were the 2 lines "Ubuntu 9.10 computername tty1 ...etc" appears and I could not login due to flickering.
