Ubuntu :: Monitor Won't Be Detected Unless First Boot Into Windows
Jun 1, 2010
So I have a Samsung monitor at work (model 2343BWX) that I use in addition to my laptop screen. My computer is a T500 think pad. When I boot into ubuntu 10.04 from previously shutting down the computer in ubuntu I can't detect the monitor. If I however boot first into windows (I don't even have to enter my password, I can just press shutdown on the menu instead of logging in, and then boot into ubuntu) and it auto detects the monitor.
I have tried going to System -> Preferences Monitors and clicking "Detect Monitors" it doesn't work. Anyone know how this could be?
I'm running 10.04 as a DVR (mythtv). If the computer boots with the TV off it won't detect the settings, and when I turn the TV on nothing displays. I have to ssh into the computer and reboot it to get it to detect the display.Any idea how I can go about solving this? How can I disable autodetect and force it to use a specific setting?
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.
Code:
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 have a laptop with a busted screen and no way to boot directly to the external monitor with ubuntu installed and the thing is I want to install windows 7. Anybody know of anyway to do this without being able to see the screen before the os loads? So far I have messed around with installing windows 7 in vm box and trying to turn the vdi file into a valid partition and also tried installing it with wine but it couldn't find the temp folder to copy the install files.
I have installed (successfully) Ubuntu 10.04 ppc on my powerpc g4 mac. 400mhz, 1g ram. Its the blue model. It works great, but it does not detect my monitor, and I can not change the settings past 800 X 600. I am using a Dell 19 inch monitor. Analog input (not DVI yet) resolution 12080 x 1024 60hz. I believe I need to change the info in the xconfig file (but I don't know to what or how), and I may not be saying that correctly.
My Ubuntu server box, has a Iiyama prolite LCD, 22", 1680x1050, that had not problem at all since... I can remember. Since yesterday, after a restart, xserver started in 640x480, with only 320x240 as alternative.
I have latest nVidia drivers installed, and the main difference with last week, is that now, Display Configuration says CRT-1, unknown instead of Iiyama.
I've tried.
1. Uninstall xserver and reinstall. 2. dpkg reconfigure 3. Uninstall nVidia and come back to original Nouveau.
I install the debian on my PC, but the monitor is not detected or not adapted ( while it is for linux CD live, and windows XP). it gives the following errors :
I want to use the file xorg.conf given by CDlive ( sidux for example) and copy it in the /etc/X11 of my debian, is it enougn or I need ohter configuration ?
After around 30 minutes, I came back and switched back on the pc.
The primary monitor (VGA) was not detected, even after a system reboot.
More info about my pc: Debian stable 8.2, kernel 3.16.0-4-686-pae. I have an Nvidia card, but currently I am using nouveau drivers. Two monitors: VGA (primary) and DVI (secondary).
Later I could get my primary monitor to work by switching tty (ctrl+alt+f3 and typing "startx" in the console).
I guess this is related to Xorg configuration (/etc/X11/xorg.conf is empty), but I am not really sure.
I have a ViewSonic (VA1703w) LCD and Fedora 14 is not detecting it. I want to change the resolution but it is fixed to 1024x768. I have also tried to add the resolution in xorg.conf but no effect.
I noticed that Debian 8 has a significant bug related to detecting presence of display(s). Today, I woke my computer from sleep while the LCD monitor was unplugged from power (the monitor is connected via DVI) then I powered the monitor but nothing was displayed. Next, I connected another monitor via HDMI and both screens started working. However after disconnecting HDMI cable from the second monitor the first one with DVI stopped showing anything. The conclusion of this situation is that HDMI monitor must be connected all the time.
I thought that this is caused by graphics driver, but I experienced the problem on different machines, one with nvidia driver and DVI, and the second with default free driver and DisplayPort.
I just checked that this is related to KDE. After switching to console using ctrl+alt+f1 the screen turns on, but when I am going back via ctrl+alt+f7 the screen disappears.
I'm using i386 Jessie Debian, have an i7 Intel processor and Gtx 745 4gb NVidia GPU.
I am running with nomodeset due to blurring issue but issue occured without nomodeset too.
Problem:
When I start Debian with just a monitor in the HDMI slot it doesn't recognize the monitor and keeps the monitor at 1024x768.
When I start Debian with monitor in both DVI and HDMI slot it only activates the DVI monitor (with proper resolution). PC has no VGA I have no DP cable.
xrandr: xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 0mm x 0mm 1920x1080 0.00* 1280x1024 0.00 1024x768 0.00 800x600 0.00 640x480 0.00
Which is my dvi monitor, no other screens detected. Is there any way to get the HDMI to run properly?
My system can't seem to detect the external monitor that I've plugged into my laptop using and HDMI cable. The monitor works when I'm booted into Windows so I know that it isn't a problem with the monitor or the cable.
When I run xrandr I get.

I've recently installed Debian v8.1 and installed Nvidia driver 340.46. In nvidia-settings I am able to enable my second monitor and enable it/set it's position..etc. My second monitor is not being detected in Debian Display and is 'on' but only showing a black screen. I've tried researching and implementing various 'fixes', but I'm not having any luck.
I'm running dual GTX 570's with a monitor plugged into one each (DVI). I noticed in my xorg.conf under Section "Screen" I have an option "MultiGPU" "Off"; would this be part of the issue?
I've tried: - purging all nvidia drivers and re-installing - installing different versions of nvidia drivers - add nomodeset in grub
Today my desktop reverted to 1024x768 resolution immediately after init. I tried changing it back but only 1024x768 and 800x600 are listed as supported in the display settings, even though my monitor supports resolutions of up to 1360x768. Rebooting the system did not solve the problem.I'm running Fedora 15 x86_64 on kernel 2.6.38.8-35 with the proprietary nvidia drivers of version 275.09.07. My monitor is a Samsung SyncMaster 933n. nvidia-settings is apparently not detecting it correctly, it thinks I'm using a CRT monitor.I was actually in this exact same situation a few months back, but it kind of went away on its own, so I didn't mind too much. So, what could be causing this, and what can I do?
I haven't manually configured XWindows in a very long time, so I'm not very certain what I need to do anymore. Hopefully someone can provide some guidance. I just built up a new system that I'm trying to connect to a 47" LCD TV that provides a VGA connection. When the computer starts booting all of the text comes up just fine (1 or 2 characters on the left are chopped, but otherwise fine). When I tried to run the installer for CentOS5.5 I ran into a problem. The monitor(TV) wasn't getting a proper signal to display XWindows. In an effort to keep going, I reconnected the PC to an old monitor and did the install from there. That worked no problem. I ran all the latest updates hoping that maybe this was fixed in a patch. I then shutdown and reconnected to my TV. no luck. When it starts XWindows the screen doesn't display anything. I've tried fooling around with modifying the xorg.conf and adding an explicit "Monitor" section and set it to 640x480 with a VertRefresh of 60 (which is supposedly an acceptable format), but no luck. Can anyone provide any guidance on how to solve this problem. BTW I do know that the VGA connector on the TV works just fine because I can hook up my laptop (Windows XP) to it.

Installed fedora 13 to hard drive on fresh partition,installed ok,ran updater,installed all updates.all working ok but fedora is not able to detect my laptop monitor.i am unable to increase resolution.stuck on 800 * 600. when a window in open and i need to click at the bottom of the window i cant because it is bellow the screen.I went to [URL] to look for drivers.it only shows display drivers for red hat 7.0.i tried them but wont install.is thier drivers i can use for fedora 13,or a way to force resolution into 1024*768.
OS: Fedora 12 Video card: ATI Radeon 9200 series Monitor: ViewSonic 19"
I installed Fedora 12 configured Gnome automatically. Generally default settings. My monitor was connected directly to the video card and all was good. My video card was detected and my monitor was detected as ViewSonic Corporation 19" and I can set the screen resolution to 1280x1024. I had no xorg.conf file, as it seems that Fedora 12 does a great job of PnP to just set everything up.Now I go and complicate things by hooking up my monitor through a KVM switch. All of a sudden my monitor is "Unknown" and the best resolution I can achieve is 800x600.
Sure, I could go and reconnect without the KVM, but I want to be able use it.Is it possible to edit xorg.conf to tell it "Trust me, just use 1280x1024 at 60Hz even though you can't figure out what the monitor is"?
I tried a number of the posted suggestions to generate xorg.conf files but none of them get me what I need. A simple sample file listing that does the minimum is greatly appreciated (I can experiment from there once I get a basic setup working).And can someone explain if it is X or the ATI driver that is getting confused by the unknown monitor type. It helps to know what is actually going on in addition to a fix (so I can figure it out myself in the future). Thanks!
I installed a new copy of F13 this morning on my fairly new laptop.32 Bit Intel, 3GB Memory 120GB HDD. The problem I've got is that my Monitor/Graphics card is not getting detected and as a result I'm getting a horrible Resolution/Refresh rate. When I run
lspci | grep VGA
I get this 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 771/671 PCIE VGA Display Adapter (rev 10). how I can get my monitor/graphics recognized to work in the Full Resolution.
I found this thread by looking up ultramon replacement: [URL] I would like to use "swapmonitor", to make it easy to move windows from monitor to monitor in a dual desktop environment. I have no idea how to install it.
I am new to Ubuntu. I installed Ubuntu 8.04 and it detected my Acer monitor AL1716 correctly and it works fine. However when I installed Ubuntu 11.04 it shows the monitor as " Unknown Monitor" and the maximum resolution is 1024x768 and I cannot set the native resolution which is much higher. My motherboard has Intel 845G chipset and built in graphics. I tried Ubuntu Software Center, but couldnot solve the problem.
I recently installed ubuntu in my dell inspiron n series, after installation only ubuntu is in grub configuration. Windows is not detected by grub. Here is what i get if i do fdisk -l
I've got 2 HDDs. Ubuntu 10.04 is installed on the first and Windows on the second. But Windows is only on a small partition for special cases. Therefore I don't want that Windows to be included in GRUB whenever the kernel is updated or whenever I run update-grub. If I really want to start Windows, I am able to do so via a menu from BIOS.Is it possible to permanently exclude Windows from grub or disable GRUB's autosearching for other operating systems?
i had windows 7 pre-installed in my laptop. i installed ubuntu 11.04 by making a bootable disk and did the partitioning so that both windows and ubuntu boot options would come on startup. however , when i switch on the laptop . the options do not come and ubuntu boots as if it is the default. i thought this might be due to a problem with grub 2 so i re-installed it. yet there was no difference. i want to uninstall ubuntu now. but how do it? most guides require me to access windows and create a rescue disk and changing the MBR. but since i cant access my windows partition this isnt an option. so there are 2 options for me - to make grub detect windows during boot and then use windows to make the MBR rite or to delete the system files of ubuntu to make it unbootable?
i'm currently using ubuntu10.10(/dev/sda10) and win 7 is installed on /dev/sda1.
during installation of ubuntu bootloader failed to install.so i had to do it manually later.but now the problem is that is does not recognise my win7 os.
i have tried many different suggestions given on this and many other forums but none worked.i even tried going back to grub(legacy) but that to didn't help.editing the menu.lst didn't work nor did the sudo update-grub did.
i also used the boot_info_script.it detects my win7 partition.if u want i'll attach it here.
I have installed ubuntu in my windows vista using wubi. Wireless isn't working in ubuntu, so I have to install Broadcom STA proprietary wireless driver and it works fine in ubuntu. when I reboot into windows, to my shock, hardware isn't been recognised in windows. This is not first time I experienced it. I had same problem when i installed nvidia drivers on another dell precision. Its graphics got screwed and never been recovered. I tried re installing windows but problem still persists.
using #fdisk -l.my friend show me like this.i have 4 hard disks, but he didn't.. but only 3.Was there anything wrong? when i installed linux and maked config?(e.g> i have miss on setting disk partition matter) and when see below result, the device sda2, sda5 start same address, end too.is there anything wrong with my disk? i have seperated 4disks.. C:,D:, G:,H:
Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe9ffe9ff[code].....
for some reason, ubuntu cant see it anymore. so how to fix? windows still prints to this printer on the network. I deleted the printer in ubuntu and tried to redetect and now it says no printer at that address.
before I deleted it, I recall it saying something about the backend had failed?
I'm using Maverick Meerkat, 10.10, 64bit. I'm a pretty basic user but am trying my best to learn.
My background: I have a laptop on which I installed Win7 Ulimate on one partition. After installing Win7 I then installed Ubuntu on a separate partition. GRUB2 found both Win7 and Ubuntu perfectly. I could choose to boot into either one and the ability for GRUB2 to "remember" which OS I booted into last worked properly. I then did a kernel update a couple days ago via Ubuntu's Update Manager. After that, GRUB2 could no longer see Win7. I added a custom boot entry in /etc/grub.d/ so that Win7 would show up in GRUB2.
However once Win7 did show up in GRUB2 I kept having a problem with the Windows bootloader being missing. I used the Win7 Recovery DVD to get into Windows and then installed EasyBCD for Win in which I was able to create a Win7 boot entry and get the Win7 bootloader back. I set EasyBCD to skip the bootmenu so my current configuration now is that on bootup I see GRUB2, which shows Maverick Meerkat & Win7. If I select Win7 then Win7 loads via EasyBCD and it works fine.
The problem though is that GRUB2 does not auto-detect Win7 AND it no longer remembers the last OS that I booted into. I would rather not use EasyBCD if I can help it and would like to just use GRUB2 for everything.
My question is this: How can I get GRUB2 back to controlling Ubuntu & Win7 properly without the need for anything else in between. I have asked in the Freenode Ubuntu channel but haven't received any help besides "sudo update-grub" which I have done and it hasn't helped.
