Ubuntu Multimedia :: Black Screen On Laptop's External Monitor When Specifying Vesa Driver In Xorg
Jan 16, 2010
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:
So, following advice for similar freezes I've seen, I have added the following options to my grub menu.lst on the kernel line:
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:

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again. When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a netbook (Acer Aspire One) I'm running Slackware 13. and usually, I prefer to connect an external monitor. When I switch my machine on with the monitor connected, the display is duplicated on both screens and since I just want the netbook's screen to be off and only see the display on the external monitor, I can doxrandr --output LVDS --off
Great! However, it's a hassle to do this every time I log in and I'd like to automate the process if possible. I did some googling and I found that if you want to automate xrandr commands, you can put a script in /etc/X11/Xsession.d/ (see this). I wrote the following script to automate my xrandr commands and since the Xsession.d directory didn't exist, I tried creating it. The script was called 45custom-xrandr_settings, as the one on the RandR wiki is called the same.
Code: #!/bin/bash # Check whether the external monitor is connected
Here goes the problem: I have a Amilo M7400 notebook with an Intel 82852/82855 GME video card, and X is a bit uncompatible with it.I've tried using the vesa driver in the xorg.conf, but when i start Xserver, it hangs hard in a blank screen. I can't open a new terminal and control+alt+backspace won't work.
what can i do? is there a log file for X which details the initialization of it?
With the upgrade to Squeeze and the 2.6.32-5-686 kernel, my Dell GX260's 82845 video chip suffers from the documented intel driver bug (freezes within a few minutes). I tried to fall back to the vesa driver, but am only able to get 640x480 resolution. The monitor is an LG L1720P.
I turned off kernel mode setting (via /etc/modprobe.d/i915-kms.conf), and modified xorg.conf -- added Modeline entries (from gtf) and additional Mode lines to try to force resolution. Relevant portions of xorg.conf, dmesg and Xorg.0.log are shown below.

I have Ubuntu (running Jolicloud) on my HP dv2000 laptop, connected to my Sony AV Receiver through HDMI to use the TV as an external monitor. However, the resolution seems to be slightly off as the outer edges of the screen are cut off. Is there a way to fix this by editing the xorg.conf file? My current setup is below. I tried adding the line "Virtual 1244 700" to the subsection "display", but when I restarted it threw me into low graphics mode. Is there anything else I can try?
I also tried setting up the resolution at 1920x1080 on the TV and kept the default resolution on the monitor as 1280x800, and as you would expect displays the entire desktop in a smaller version on part of the tv. However, the desktop is still offset, leaving the top and left margins cut off. So, perhaps I need a way to offset the screen? Is this possible in xorg.conf?
I have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.
Pretty much what the title says.. a few more details:
- I installed 10.04 using the alternative install so I've been doing all this in safe mode - I installed a newer kernel (2.6.33) and still black screen - I tried to install an updated Intel xorg driver, but I kept getting dependency errors (xorg, x11, something else)
I read another thread on this forum from a user who is using the same platform (Intel HM55), and I got stuck at the last point (can't get Intel xorg driver to install).
Just did a fresh install of Natty B1 (previously had alpha 2).. I noticed this issue w/ A2, as well.. plugging in the exterminal monitor (via mini-displayport-to-vga connector) will do the following:
1) turn the screen on the laptop's display entirely black (but not turn it off).. i can move and see the mouse cursor.. but everything on the window appears to not rending or "painted" black..
2) external monitor never becomes active..
the only way to recover is to kill/restart X or reboot after disconnecting the extmon.. having extmon plugged in from boot produces the same results (and it doesn't seem to ever become active during boot up). sometimes this won't happen right away if i plug in the external monitor.. but opening the Monitors system prefs dialog will definitely cause (or detect displays) ,etc I waited to see if the issue would fix itself w/ the beta update, but it hasn't.. Any other 8,1 owners out there that can verify this issue? My (totally uninformed) guess is that it's due to differences in the display/gfx hardware and thunderbolt integration(?)
(I've seen a verification verifications of working-out-of-the-box.. but they were from 8,2 and 8,3 owners (which have discrete graphics cards))... If anyone's gotten this to work with some config stuff, I'd love to see that as well (since the wiki page for 8,1 says it works ootb). If someone could let me know where I should look to capture error output when the above issue occurs, that would be awesome.
The laptop is a samsung X30 and i spent days trying to install ubuntu 10.04 unsuccesfully as there was no clear picture on the screen, just a black and purple splodge. I then saw a post on these forums discussing the default resolution of ubuntu and how it is incompatible with some machines so via VGA cable i connected it to my TV and sure enough i could see what was going on and finished the installation process. I assumed that once ubuntu was fully installed i would be able to change the resolution using the monitor preferences but none of them worked. I am now faced with the problem that unless plugged into the TV i have no picture on my laptop, does anyone know why my laptop screen wont work with ubuntu and how
I'm a new user and recently installed ubuntu on an old samsung laptop, during the installation process i couldnt see anything on the screen and came to the conclusion that ubuntu's default resolution was different to that of the laptop screen so i plugged it into my TV and sure enough it worked however i still only have a picture on the tv, ive tried all the resolutions available in the 'monitors' box but nothing, does anyone know how to fix this?
Got a problem with Ubuntu 9.10 and a Lenovo T400 with an ATI Radeon Mobility HD3400 and ATI drivers /ATI contol center. Whenever the laptop wakes up from power-saving mode, the screen goes black (with some jagged mulicolored lines).
I have a laptop and an external monitor connected via displayport. I can configure both displays via settings with correct resolution and arrangement. However, this configuration is not sticking, and every time I shut down the laptop or close the lid I will need to fight with black screens and more to bring the same configuration again. Basically, it seems that the monitor is "stealing" the primary role to the laptop's native screen (I have it configured as secondary, but also being primary the configuration gets messed).
After many trial & errors, this is the routine I have found to make things work every time I boot / awake the system:
1. Boot. Laptop's display shows the booting sequence. 2. When the login screen should appear, laptop's display goes black, monitor shows background. 3. If I press F9 to increase brightness, the brightness icon appears in the monitor, but it is stuck at the minimum. 4. The only way to leave this point is by pressing F7 (project screen) and then F9 again to increase brightness. Then the laptop's screen does light up.
This is when I'm lucky. Sometimes the configuration goes mad and I get mirrored displays and different resolutions, without touching the settings myself. Also, if I unplug the displayport I run the risk of getting stuck with a black screen in the laptop, without any way of recovering the GUI other than rebooting (Ctrl Alt F2 will still show the command line screen).
My system is Debian 8 testing up to date, running in a Lenovo T430 with Intel components. I'm not sure the monitor is relevant here, but in any case it is an Eizo CS240.
I am running Debian 8.3, and I'm running Gnome 3.14.1.I have an external monitor plugged in with HDMI, and while Linux is loading both screens are on duplicate. Once the GUI kicks in, only the external screen works, so I have to enter my password blindly. Then, I open a terminal and run
I have an HP Pavilion dv9000 which I would like to use completely with any Linux OS. I have tried to install Linux Ubuntu 10.04.1 but it appears that it doesn't recognize the external monitor and ends the installation. I have a clean hard drive that I could install but I do not know which of the two drives I should replace. I can only get into windows in safe mode and I would think this may have something to do with the problem, don't no.
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.
I have a Dell XPS M1330, which has a GeForce 8400M GS GPU. The binary (sigh) nVidia driver installed is version 190.53 (installed by sgfxi). This is working well: glxgears gives me about 2600 FPS and compiz is happy.An old Philips 170B is attached by VGA cable. I was looking to set up a method of switching resolution upon connecting to the monitor when working at the desk, since I don't like the 1280x800 resolution of the laptop.
nfortunately, I can't get any output on the external monitor. It does work under Ubuntu, which installed the 180 series binary driver. (Going to an earlier driver is an option, but I want to understand the problem.) Bottom line, I want to work under Debian.As far as I know, nVidia's proprietary driver doesn't support xrandr. At any rate, with he external 170B monitor attached and turned on, I get the following:$ xrandr -qScreen 0: minimum 320 x 175, current 1280 x 800, maximum 1280 x 800default connected 1280x800+0+0 0mm x 0mm
I am running Ubuntu 8.04 on a laptop. I have a 19" Acer monitor and in the past have successfully configured my xorg.conf to handle dual monitor setup with 1024x768 on the laptop and 1600x900 on the Acer monitor. What I have done now is run the laptop through a KVM switch. Due to this, I would like to set the Acer monitor as the primary monitor and just shut the laptop. How can I project my laptop screen to my Acer monitor so that I can use the 1600x900 resolution available rather than just cloning my laptop and using 1024x768?
The monitor on my laptop has become a bit sketchy and money is tight at the moment. I am currently connected to an Acer flat screen monitor. I have the ubuntu settings for using only the external monitor. This works fine once I"m in Ubuntu. Is there any way to force the display to the external monitor prior to ubuntu starting? This may or may not be a linux-related question. It was be very helpful if I could see my Grub menu on the external screen. I could not find any setting in my bios. The keyboard shortcut sometimes works but not on the grub menu.

I'm trying to remove 3Dlabs / Oxygen gmx , and install vesa - Generic VESA-compliant video driver module.How do I remove 3Dlabs / Oxygen gmx ?I can click on VESA in the 'Choose By Name...' , but when I close that box, it shows No Driver.
I'm running Debian Squeeze on a Dell Studio 1558 laptop, and I have my laptop set to suspend when my lid is closed. Resuming from suspend seems to work but the screen remains blank, forcing me to hard reboot every time. Upon reading this thread:

When my netbook has an extended screen, using an external monitor, all of the panels stay on the netbook, not the big monitor. When I connect an external monitor, I want to use it as my primary screen. I only really intend to use the netbook screen for skype calls (so I am looking into the webcam, and not away from it) since it is so small. I wish the secondary screen to be the netbook, not the external monitor. How can I do this?
My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.
I recently swapped a hard drive from another computer I was using.The previous computer had nVidia video card (i think it was 9500? something like that), and the new computer has an ATI Radeon 4200 HD video card. Now, when I boot it up on my new comp using the same hard drive, I get a black screen and my monitor just switches from digital, analog, hdmi. I'm guessing that the video card drivers are still installed, but I cannot switch back the hard drive since my other comp is far away from where I live. If I boot up with ubuntu CD however, it loads fine.
I have many important files on the previous install though, and I'm not sure how to get to it. I wouldnt mind reinstalling ubuntu as long as I can get those files back.
Where the script is for Gnome 3. When I plug the HDMI cable, the desktop expands to include both, but disables the backlight on the laptop monitor. I have to restart gdm3 or the laptop for the brightness control to bring it back up. First, why would it turn brightness to 0, and how do I change the default of that so it stops. I plug and unplug the HDMI regualarly while I wait for a new desktop and the laptop has to pull double duty.
I just switched from Ubuntu 14.10. It never blacked out a screen on plug in or removing. That means that there must be some way to do it, however, it used Unity and this is Gnome 3.
I installed KDE. It works as well. I will use it for now, but would like to get Gnome 3 to work. My default is gdm but I think I saw I can switch it to kdm.
I recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.
My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).
I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.
A few days ago I installed browserlinux onto my AspireOne netbook whilst connected to a 15" external monitor of 1024x768 at 60Hz. During installation I ran the Puppy Xorg Wizard with the netbook's monitor (1024x600) switched off. It selected the optimum resolution of my external monitor correctly as 1024x768 and the 'intel' driver for the Intel 945 Express chipset. However when I ran programs and maximised their windows they would cut off about a third from the bottom. I ran the Xorg Resolution Wizard which showed a resolution of 1024x600 despite xorg.conf only showing an option of 1024x768. I tried to copy a xorg.conf from Linpus (Fedora 8) which had required some altering in the past to run the external monitor at the correct resolution but X failed to start (possibly because Xorg in browserlinux is a newer release). Would it be possible for someone to upload a xorg.conf file which would enable display the external monitor at the correct resolution (and ideally allow switching between the two monitors - under Linpus the hotkey is Fn + 4) or suggest alterations to the current file?
