I've experienced 3 1/2 years of Ubuntu bliss. I have run into the first issue that I cannot solve using these forums, and I'm at my wit's end. Problem: I cannot start gdm (gnome?). I get the "Fatal server error: no screens found" error. Also, my terminal screen is duplicated on the top and bottom of the laptop monitor, indicating something gone terribly wrong.
When the problem started: immediately after running standard update to 2.6.32-26 (this time). Last time, it happened after running a standard update, but that was weeks ago. I did a complete reinstall (three times, including once to 10.1)
My system:
Ubuntu 10.04.1 LTS (clean install + recent updates)
Kernel version 2.6.32-26
Also have 2.6.32-25. Neither one works in recovery mode, either.
Machine: Dell Inspiron 1420
Intel Core2 Duo
Nvidia GeForce 8400M GS

Running Ubuntu 10.10 x64, fully updated kernel and stuff, in VMWare Workstation 7.
Before I tried installing the Nvidia driver, I set up all my stuff, settings, etc. Restarted several times, everything went okay.
I then decided to install the Nvidia drivers for my GTS 250. I first tried the manual install (sudo sh NVIDIA-INSTALL-NAME.run) and it failed saying something about the nvidia.ko or nvidia.so. I tried using this page http://ubuntuforums.org/showthread.php?p=9203671 to fix it, but it still failed, so then I used the automatic method (sudo apt-get install nvidia-current) and it installed fine, then I ran nvidia-xconfig and restarted.
The VM started up, but no GUI came up, instead, a black screen with a terminal (I think it's called a Virtual Terminal) came up and asked me to log in. I tried the command "startx" from there, and it told me no screens were found.
What can I try?

I reinstalled and forgot how I added a panel to my second screen, cause when you add a panel you choose left right top or bottom, but no option for second screen... finally I added a new panel, then right click on the new panel> properties, then unchecked "expand" then was able to move the new panel to second monitor, then set to whatever side and recheck "expand" then it sticks to the second screen, then add to panel, and select window list, then all new windows will be shown on the appropriate panel/screen

I'm trying to install 10.04, but have hit a few bumps. The first time I tried to boot the live cd, the monitor frequency would go out of range. I fixed this by deleting the
Code:
ro quiet splash
from the end of the boot line, and replacing it with
Code:
ro vga=773 nomodeset
After booting with this modification to the kernel line, rather than booting into the live cd desktop, it takes me to a command setting. To try and get things moving I type

I have a Dell Vostro 3300, i5 460 processor with a NVIDIA 310M Graphics Card. I'm doing a KUBUNTU 10.10 (Maverick) install with the following results. The Live CD boots just fine to, "TEST," or "Install." Installation goes fine. However, the graphics card being used is the Intel i915. I have tried installing the NVIDIA drivers directly from the, "Additional Drivers," tool and after the reboot I get through the boot screen to the console. I try to manually startx and I get the errors, "no device found," "no screens found." The second install I tried purging and blacklisting the nouveau drivers and entering safe mode. Then using apt-get install nvidia-current. After that, nvidia-xconfig. Same results.
The third attempt I re-installed and this time downloaded the drivers from the Nvidia site (version 256.53). Blacklisted nouveau, remove all nvidia, updated initramfs, etc. The install went fine however I still end up at a console after boot with the same messages as above. No device found, no screens found. I've tried searching through the forum and web and have tried things like adding the modset option along with many other hacks, tips and fixes. still, no go.I can live with the Intel graphics for now although I lose 512MB of memory. Unfortunately there is no way to disable or change this set-up in the BIOS. I've seen quite a few bug reports at Launchpad:
1. Is this something I should just wait til a fix comes? Will a fix come?
2. Is there, or will there be an official Updated Ubuntu Guide for Maverick to install NVIDIA drivers with this tecnology?
3. Lastly, is there anything else I should try??

I downloaded the new gparted (6.4.1 I think) and when I try to run it from a live cd in the default settings it keeps telling me that it can't find my screens. I have an intel video card. I haven't had this problem with older versions of gparted. I suppose I could use an older version, but I'd like to know what the problem is.

Some background to summarise, I have installed 10.10 clean over the top of 10.04. I did not have X/display problems on 10.04. After installing the Nvidia display driver for my device (Asus 8800GT - display driver: NVIDIA-Linux-x86_64-260.19.12.run) in order to get dual-headed display working under TwinView (as I had previously have used on 10.04 problem-free) I cannot reboot/shutdown my machine without a Fatal Error No Screens Found message appearing at boot time.I can hibernate, but this is less than ideal, especially after installing updates which require a restart. Every time this does happen I can re-run the driver installation and all is well again.Below are two copies of my Xorg log. The first is the erroneous log, the second the successful log. Below that is my xorg config file generated via nvidia-xconfig.

I was trying to install the nvidia drivers then when I reboot all I get is a command line. Startx does not work, it says no screens found. I was dumb and uninstalled the nvidia drivers too not realizing my internet didn't work in the command line. I need to install the drivers from the live cd unless there is another way. I don't want to have to reinstall!

I just installed Maverick on a brand new system last Saturday. Everything worked, except dual monitors, so I activated the proprietary ATI/AMD driver. That allowed the dual monitors to work, except that it put a little "AMD unsupported hardware" watermark in the lower right-hand side of each screen. After a day or two, I decided to go back to the default driver while trying to figure out how to avoid the watermark.
I assumed that when I deactivated/removed the proprietary driver that it would automatically switch back to the default. Instead, my computer now boots to TTY1, and when I try to install xserver.xorg, etc., I get a lot of error messages,ike "No screens found" or "Screens found, but configuration is unusable," etc. The same messages show up in the logs.Can anyone help me get back to a useable desktop display? At this point, I don't care which one. erhaps the proprietary would be easiest since it seems to be holding my system hostage, but either one would work.

Ubuntu 10.10 Whenever I try to boot up now I get a command line environment instead of the normal gnome desktop. The first error message that comes up is: "Screens found,but none have a usable configuration" further down: "Fatal server error: no screens found" Any way I can re-configure so it detects my monitor?

I use multiple screens on my computer in work which is running Ubuntu 10.04 it runs great apart from the VBox VM. I run a windows VM as some apps we use in the office are not compatible with ubuntu and I can't get them running right in wine. In single screen mode I use the VM in 'seamless' mode so the windows start menu just sits on top of the ubuntu panel and I can flip from ubuntu to windows as I please in the same interface (im sure anyone that uses VBox will understand what I mean).
The problem comes when I use a second screen. If I try to run in seamless mode on the main screen it works ok apart from the fact that the windows start menu sits behind the ubuntu panel instead of on top of it. When I move the VM to the second screen I cannot run it in seamless mode at all, if I try the resolution goes hay wire and I only get half the screen (if im lucky). So I just run it in full screen mode which stops me from dragging windows from within the windows VM back to the first screen.
What I want to be able to accomplish is to run the VM in seamless mode on either screen but be able to drag windows accross both screens. Is that at all possible?

I've installed 9.10 on a work station with success. I've got an nvidia quadro fx 3000 and its supported under nvidia legacy driver apparently. So I've tried to install the driver with no success. Xorg.0.log reports a fatal server error no screens found. I get a flashing console login when I boot with "nvidia" device driver in xorg.conf, it boots fine with "nv". No matter what I try I cant get it to boot with nvidia drivers. Also, on a side note, after initially installing nvidia driver thru hardware in gnome, I no longer have a grub loader option to select recovery or anything else. Upon boot it displays "grub" briefly then continues to boot to gui. I've set the delay to 20 seconds with no results.
Resolved the issue of the display, now on to the grub menu.

I installed debian 4.0 (etch) on an old computer with some pickled graphics card in it, and then I upgraded the computer to one with slightly newer hardware only without the graphics card (the new one used on board graphics). I moved the hard drive from the old one to the new one but when I booted it up it failed to start the X-server and I got some errors listed for "device not found" and "no screens found".
I tried using "dpkg-reconfigure xserver-xorg" however I can't seem to find a working configuration. It seems pretty silly that when installing debian it can detect all this automatically with no problems but when it comes to changing some hardware around you are left in the dark with a complicated re-configuration process. Is there not some way to automate this? I'd rather not have to re-install everything

I previously used 11.1 with KDE 3.5. Since I have /home on a separate partition I decided to install 11.2 from scratch to avoid any conflicts with KDE 4 installing. No problems on first reboot and some updates were installed. Now at each boot I'm dropped into text login. If I try <startx> I get <no screens found> and /var/log/Xorg.0.log gives <screens found but none have usable configuration>. However if I add vga=952 at the boot screen (for a 1280x800 laptop) I get into graphical login and everything works well (yes even KDE 4). Below is an snip from /etc/X11/xorg.conf.

My issue began with my resolution changing to 800x600 in Karmic Koala and then my inability to change it back to anything else. In my haste to fix it before going to work this morning I loaded a new xorg.conf without backing up the old xorg.conf with data not relevant for my monitor and now I'm in limbo. The good news, I hope, is that I also run 8.04 on the same computer so I do have access to what I hope is proper xorg.conf / I've modified the existing xorg.conf file and I'm still getting the "low graphics mode" message (EE) problem parsing the config file and (EE) Error parsing the config file. Fatal Server Error: no screens found.

I have dual monitors that I have set up with two separate X screens with the nVidia control panel. For some reason at times when I move my mouse between the two screens, the cursor will start flickering rapidly between the adjacent edges of the screens and the system will become completely unresponsive, forcing me to do a hard reboot (the keyboard doesn't have a SysRq key).

how Xrandr supports Dual screens. I am attempting to setup Dual Screens on a Ubuntu 10.10 System with an ATI twin head card (DVI + HDMI) Non-mirrored, separate desktops However on connecting a device to the HDMI output - the DVI screen output appears to loose all panels, icons. Only the mouse pointer & desktop background remains.
I believe the output is defaulting from screen 0 to screen 1. I found a solution by creating two devices in xorg.conf and assigning one for each separate screen. BUT this created a new problem of loosing my mouse pointer. how I can get my mouse pointer working or the correct way to setup dual screens.

there are several posts related to my problem but not quite what I want. I don't need any effects to be running nor do I need perfect resolution. I have a PCI-E card Nvidia 8600 gts and I need to run redhat 7.1 for reasons that are not debatable. I also have an onboard ati radeon X 1250 but currently I am running the PCI-E.The installation was successful and ran in GUI, however after installation and reboot, the screen keeps flickering trying to load the desktop.I just need to get the GUI running the same way the installer was able to run in GUI, I tried editing the XF86Config file to change the driver to either vesa or vga but still didn't work. Probing for devices is not an option since the card is not listed and the maximum video ram goes up to 64MB in xconfigurator. It probes my card as a VGA generic with 1 MB ram. I know there is a way to have the desktop load just the same as the installer's gui settings but that's where I need help.
this is after changing all the 'driver' values to vesa. I don't understand why it can't find the screen even though I used the horizontal and vert. sync values for my monitor. Any instructions or advice on how to just get the desktop loaded would be great, I know this is a very old OS but regardless I need for it to work.

My setup:
One computer running F12.
NVidia with 2 CRT outputs, and one S-Video/TV output
Standard PS2 keyboard and mouse
USB (wireless) keyboard and mouse
Sound card w/ Optical SPDIF, and standard analog front/rear outputs
At present, I have CRT-0 connected to a standard monitor that I can get resolutions up to 1920x1440. TV output is connected to a flat panel monitor, with a max resolution of 1024x768. SPDIF audio output connected to TV system, and analog output (front only) connected to destop speakers. Note that the monitor/speakers are in one room, and the TV w/ SPDIF audio is in another, with the USB kbd/mouse.
I can get a cloned twin view set up on both, with the USB kbd & mouse/TV/SPDIF mirroring the monitor/PS2 kbd & mouse/speakers - but only at a max resolution of 1024x768. That by the way needs to be the virtual screen size for the TV. If I want to switch between the two max resolutions (one when using the monitor, the other the TV) I have to edit xorg.conf and change the modes line for the display, then restart the X server.
I would like to have the monitor set up to its max 1920x1440 resolution with a virtual screen size the same, and the TV set up for 1024x768 with that for its virtual screen size. I also would like the separate kbd and mice to operate with the respective screens. Ideally, each screen would be independent of the other - running two different apps on each output, similar to separate workspaces. Is something like this possible? It's a pain to have to re-edit xorg.conf and restart X every time I want to switch from watching TV to working on my monitor.

I'm having some issues getting my two monitors (both 1600x900) to work well with Xinerama. The first thing I'm having trouble with is getting 1 wallpaper to span across both monitors..from what I've googled it's sounds like I'm not the first either The 'span' function in the change wallpaper window doesn't do it. The second thing is that I would like the panels to stretch across both monitors well, or at least be able to create another panel on the 2nd monitor which I can't do now.Here's my xorg.conf file:
Code:
Section "ServerLayout"

I'm using an Intel chipset GMA4500 and Ubuntu 10.04 Gnome. The monitor configuration tool does not seem to have an option to make the secondary screen a mirror image of the primary screen. It works fine when I connect my TV using HDMI as a second screen, but I want it to be a mirror of the primary, because some apps like Skype will only go "full screen" on the primary display.
