Fedora Hardware :: Unable To Detect Monitor
Sep 10, 2010
I run Fedora 13 in Oracle VM VirtualBox. Version 3.2.8 r64453
I did not realize that you had to install Guest Additions but after much reading I finally got it done. After I was done the max size I could go to was 1024x768. Using detect monitors I still get "Unknown" as a result.
I really don't know what else to try as I am not to proficient with the OS. I would like to run it at my monitors native resolution so I can have it on my other monitor. IE: Monitor 1-Vista. Monitor 2- F13
Monitor: Dell 1907FP native resolution. 1280x1024
Video Card: Dual Radeon 4800HD
I thought it might be something with the video card but I can not get the ati drivers to load at all. I have been unsuccessful finding drivers for the monitor.
Ok, so I got really bored and started trying it with other OS's. I installed Ubuntu and after I added the User Additions I was unable to get anything over 1024x768. Fedora is still stuck 1024x768. I also installed XP and it works like a champ.

I am using ubuntu 10.04 on a desktop PC. I have connected my 17" Dell LCD monitor with webcam (using the monitor's USB cable).
Ubuntu does not detect the webcam at all (I tried Skype and Cheese, both say no device found). (The monitor webcam works fine in Windows).
How do I make the webcam work?

I installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
Here is my current xorg.conf.
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]....

I am now using Ubuntu 9.10. The prob is I am not able to increase the resolution of display. It is showing only 800 x 600 display. While trying to increase the resolution it is showing "Unknown Monitor". So, how can I detect the monitor so I can increase the resolution of my system.

I have a broadcom 4322 with the broadcom-wl driver on Fedora 11. It worked the first time I used it, and since then is unable to detect any networks. I've tried reinstalling the driver, and it still does not work. Any suggestions?

I have a rocketraid 2640x4 with 2 500gb HDDs configured in my system. I also have a 3.5" usb floppy disk plugged in with the SCSI drivers When I boot the RHEL 5.5 x86 32 bit installer, i type in "linux dd" at the first screen. Then it asks me to load my drivers via the floppy disk which i do. When i get to the installation page of Linux after entering my serial key, it is not able to detect my HDD so i am unable to proceed. I have tried using drivers for RHEL 5, 5.1 and 5.2. There are no drivers for 5.5.

I tried to install VirtualBox 32 bit on my 64bit Fedora11 OS. I took the 32 bit version as I want to run a 32bit software. I collected all information I could get from other forums. That's what I did: I downloaded and installed [URL]
yum groupinstall "Development Tools"
/etc/init.d/vboxdrv setup
Now I got stucked with the error Qt WARNING: QGtkStyle was unable to detect the current GTK+ theme. I searched for qt or qgtkstyle on my system and found files containing both but don't know what to do here.

Debian Jessie does not detect one of my monitors (I have two) when I use the default drivers (nouveau) for my NVIDIA graphics card. It does work when I install the proprietary drivers, but then, after a couple of reboots, I get many problems (when I log in, it does not manage to load the desktop environment). I've tried this a couple of times unsuccessfully.
How to make the machine recognize the dual screen with the default drivers?

I have a new F12 install, and my syslog is filling up with messages about USB. I have 2 USB devices plugged in directly to the mobo (bluetooth keyboard receiver, touchscreen), and it keeps redetecting them and then disabling the port for some reason.
A small sample of what keeps on repeating:

I've got a headless server (32 bit 9.04/9.10, can't remember) that started refusing SSH and HTTP connections a few days ago, and I'm just getting around to hopefully fixing it. The problem is that I can't even connect to the darn thing. I've plugged in a mouse, keyboard, and monitor, but the monitor tells me that it has no signal. I know the monitor works with the computer, as I used the same one to set up the server.
Just for kicks, I even tried to put in a live CD, but that didn't help. Any ideas on how I can connect to this thing?

I'm running 10.04 on a Radeon HD 4650 card with fglrx. The driver installation went without a hitch, and the log file contained no errors.
When I try to run
Code:
aticonfig --initial
i get the response
Code:
Found fglrx primary device section
Unable to find any supported Screen sections
Running
[Code]....
My best guess is that I have to write an Xorg.conf file, in which I say what type of monitor I have.
I cannot do that, as I need to shut down the Xserver in order to make it generate my xorg.conf file. When I shut it down I get the black screen.

I occasionally connect my laptop to my TV and watch shows on the larger screen.After upgrading to 11.04, "Detect Monitors" no longer detects my TV. This worked in 10.10 and 10.04, and possibly in earlier versions.

I just switched from Ubuntu to Debian and I am having trouble doing something that I found easy to do with Ubuntu. I have a Radeon R9 graphics card from MSI with dual DVI ports and I'm trying to get xrandr/arandr to detect my dual monitors but it only detects one. I've installed all the drivers and even installed the "amdgpu" driver from the Ubuntu repository but still not detecting. What drivers am I missing?

This has been happening with the majority of screens I try to plug into, but the proprietary nvidia driver never detects the correct resolutions -__- the open-source driver works perfectly with a little xrandr magic, but I'd like to have some 3D acceleration going on. I'm using the desktop version of Nvidia ION and ubuntu 10.10, with the current nvidia driver (from the repositories). The native resolution is 1440x900 @60 Hz. Any thoughts on this? Again, the nouveau driver is great but I'd like to have VDPAU and the like working. code...

My brother got a new 120hz monitor, but can only get the old one to work. If he boots up with both of them connected in windows xp they work fine, but in Ubuntu 10 only the old one works. If he tries to detect the monitor in Display Preferences, nothing happens. The old monitor is connected to vga output (lcd with vga only) the new monitor is connected to dvi with a dual-link dvi cable. We know the graphics cards cannot provide 120hz, for now we run the monitor at 60hz until he upgrades the rest of the pc (sandy bridge i guess).The 120hz monitor worked fine until he changed graphics card from a ATI radeon 9200 to a geforce 3 ti 500.
He has tried
sudo dpkg-reconfigure xserver-xorg
and detect monitor in Display Preferences but no dice. Could he try restricted drivers?
System specs:
Ubuntu 10.04 32bit
athlon xp 1700mhz
1GB ram
ati radeon 9200
geforce 3 ti 500
lg w2363d

My netbook DOES seem to know when I plug in or remove an external monitor. Can I get it to simply auto-switch?

Just upgraded to a super sexy Asus 27" LED monitor. It's awesome, however ther are a few quirks I'm wondering if I just have to live with or if they're fixable. These may not be directly related to the monitor...hence posting here rather than hardware.Specs: Asus 27" LED VE278Q monitor. Nvidia graphics card. Dell 8100 w/ 8GB ram, 64-bit. Fedora 13 running Gnome.
The first quirk is that I have a VNC window open almost all the time and if I leave my cursor on the VNC window, the screensaver won't come on, even if no action has happened on the keyboard or mouse (or in the VNC window). It would be nice if the screensaver worked.
The second problem is that when I'm using the keyboard and/or mouse in the VNC window, apparently, the screensaver doesn't realize the keyboard is being used...and the moment I switch to a different window, up comes the screensaver.
I'm having what I think is a documented hardware issue probably related to the Nvidia driver: at infrequent times, often when I'm using GIMP or other graphics-intensive program, the screen will flicker and/or go completely black for a split second. Distracting as all hell, but not a show stopper. It does not appear to happen when I'm using the web or doing other non-graphic intensive stuff, so I'm guessing this is not the monitor itself, but rather the card or the drivers for it.

When I'm connecting second monitor to the laptop, Display Settings applet (and xrandr -q) does not detect full list of supported resolutions. I need to restart my system or perform Log off while monitor is connected to make full list available.openSUSE 11.4 32 bit, Ati Mobility Radeon HD 3450, proprietary ATI driver 11.3 8.831.2-110308a-115935C-ATI.External monitor is FullHD SyncMaster B2330 (1920x1080)I wonder is there any other workaround to access full resolution that does not require restarting of the system?

This was weird. I just updated my software, through a "setenforce 0" and root shell access since the last update before this left me with a bugged GUI updater, restarted and then logged back in to . . . no users visible in GDM at all. There was nothing but a huge "Other" box staring me in the face. I got the idea to check /var/log/messages and then the GDM greeter logs from there, and here is what I came up with.
/var/log/messages

I installed Fedora 11 on my system (see below) using the i686 DVD. The graphical install worked just fine, and after the system booted back up, the X server was working very well.
There is no boot text. On the other system with Fedora 11, I can see the boot text scroll by in the window and/or a progress bar at the bottom of the monitor during the boot sequence. On this system, the monitor says "No Input", and nothing appears until the login prompt for the X window. I am able to enter the BIOS configuration page and navigate through it without any issues. I can also edit the grub commands before Fedora loads without a problem.
If I boot in text mode, no login prompt appears. If I wait long enough, the monitor enters the power save mode since it is not receiving a signal. I am able to log in to the system with my user name and password, and then start the X server. Once the server starts, the monitor turns back ON and all is well.
From the X window, I use the CTL+ALT+F2 key to enter text mode. The monitor stops responding. If I press the ENTER key a couple of times, then press ALT+F7, I can briefly see the text window with a couple of login prompts before the X window starts responding again.
How can I get the text mode to work? Why is there no input to the monitor when booting?
System:
Intel D945GSEJT motherboard with Intel Atom N270 processor
2GB RAM
120GB SATA Hard Drive
Fedora 11 i686

I've installed Ubuntu 10.10 on my Macbook Pro 5,5. Everything is running fine with some tweaks. Just one thing bothers me: when I tell Nvidia X Server Settings that I want to use my external screen as primary screen it doesn't put the gnome panels to the other screen, well... sometimes it does after a couple times but most of the time it doesn't.is there a way to automatically detect when I connect a monitor instead of going to the Nvidia settings? Just the way Mac OS X does?

I am running 11.04 with a dual boot of vista. I am also running virtualbox (downloaded from oracles site) I installed the extension pack from their website, I have added a new filter and I am in the user group but still virtualbox will not see the usb ports or the device plugged in. The reason for running virtualbox is if I can get the usb to work, I will then remove vista completely from my system and just virtualbox for the only two programmes that do not work in Ubuntu.

So I bought an eMachine e250 from a friend of mine, and installed Backtrack on it. That worked fine, until I realised that I didn't like KDE, and decided to get the gnome-based Gnacktrack (based on Ubuntu 10.10, so I'm fairly sure they work the same). I also have a harddrive from an old laptop that I've scrapped with Ubuntu 10.4 that I run in the laptop, and fpr some bizzare reason, neither operating system is able to detect the wireless card. It worked fine with Backtrack (based on Noppix I believe), and I'm curious as to why the wireless card hates Ubuntu so much. I know that it's unable to detect the wireless card because on start-up it says "Unable to detect WMID device". I even added the wireless card from my scrapped laptop to the laptop, and that NIC was detected just fine. (though I can't use it because the antenna won't reach the slot for the secondary NIC)
