[SOLVED] xrandr can't detect other monitor

Hi,
Here is my problem, I try to make a dual sreen by myself just by editing Xorg .conf files. But I need to detect my second monitor first.
nvidia-setting detects my monitor but xrandr (-q) don't.
Here is the conf file of my monitor :
Section "Device"
Identifier "Default nvidia Device"
Driver "nvidia"
Option "NoLogo" "TRUE"
EndSection
Section "Monitor"
Identifier "Monitor0"
Option "DPMS"
EndSection
Section "Screen"

Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x800_75.00"
EndSubSection
EndSection
Here is the xrandr -q result
agrum ~ $ xrandr -q

320x200 87.0

Since nvidia can make a dual screen with my current configuration, I don't think I have to edit it. But I would like to knwo how to detect my second monitor, get its name, if its a VGA, DVI, CRT ...
Thanks.

@wangcutopen, this thread is half a year old. I suggest you use nvidia-settings to do your setup for your nvidia card. Search the wiki for 'nvidia', or go to nvidia's linux forum. Try google after that.
If all those steps don't work, then open a new forum thread. But only after trying all those.
EDIT: re-opening, misread the dates on the post. My bad.

[Solved] Xrandr does not detect external monitor

I recently just installed Arch linux on my laptop and decided to install the catalyst driver as well. I followed all the instructions on how to install catalyst and when I try to use the xrandr command it does not show my second monitor. I am using i3wm on the latest kernel and catalyst driver. I can also see a x cursor when I move my mouse to my other screen but it does show the i3bar or I cant drag a window to the other screen

Windows 10 elitepad in Dock can not detect VGA monitor

Windows 10 will not detect my external monitor. I loaded Winbdow 10 on elitepad 1000 about 2 days ago. This is the first time I've tried to use my extenal monitor. My elitpad is in the elitpad docking station.  The tablet id also in the expansion Jacket.  Under windows 81. I was able to duplicate my tablet display on to the external monitor over the VGA jack in the dock. Now tablet can not detect the VGA monitor.      The monitor is an HP2065 using the HP provided VGA to DVI cable.   I've tried rebooting with the monitor diconnected and then adding plugin it in . I've run the detect monitor several times.   Any one got a solution. The new HP support page does not even list tablet as an option for display support. Thank you

            Ok, thats the procedure I was talking about earlier. I did that bios default factory reset just now. First the version 6 and earlier. It didn't work so I tried version 7 and later and that didn't work. I then tried version 6 and earlier again only this time pushed F10 more rapidly and got right in right when I got to the F5 and enter portion. Then I pushed F10 again to save the change and enter again to close. The PC didn't boot up the next screen like the test said it would. So I did it all again and spent some time reading what was on the bios pages but accidently pushed ESC as the bios menu suggested instead of enter to close out   . No boot up screen again. I did another hard shutdown and then unplugged the cord for 5 minutes and this time the PC stayed off when I plugged it back in. The bios are set to default but I cannot get it to start again in safe mode or boot up. So if the power supply is working properly, and the monitor worked in safe mode, then the video card must be good. right?
          So I'm editing from the night before, its Monday morning here in Wi. and I'm sorry to say that after leaving the PC unplugged all night that when I plugged it back in this morning, the dumb thing started again without pushing the  start button.  So the only thing doing a recovery on the bios accomplished was to prove that my the video card can run the monitor in safe mode which is a good thing I guess. Hope someone has an idea as to what else I can try.-------thanks

Can't detect external monitor, shows only 640x480

Hi,
I'm using a Macbook Pro Unibody 13" 2.53GHz to connect to a Dell 2408WFP external monitor. It worked FLAWLESSLY with my old Macbook Pro using a DVI cable.
1) I first bought the infamous mini-Displayport to DVI adaptor. It didn't work (red static etc. check the page of this product on Apple's store website : you'll see it's a known issue). Cost me 35$
2) I then bought a mini-Displayport to Displayport cable. Thought it should work perfectly. It DOES NOT. The Macbook is apparently UNABLE TO DETECT my Dell and gives it a default resolution of 640x480. Which is ridiculous knowing that the Dell 2408WFP is capable of displaying 1900x1200.
It's really a pain. Does anyone know about this problem or have an idea how to solve it?
Thanks,
P.

Ok,
It was neither the cable nor the computer (thanks Apple). It was the monitor's EDID profile. Dell's problem.
There's two ways to fix this. 1) It is possible (I did it) to create a custom profile using SwitchResX. You'll need to hook up your computer to the monitor using a working connexion (I used DVI) and then use the "export" function in SwitchResX. It will give you a text file. In it you'll have enough data to fill SwitchResX' form to setup a custom profile. You'll then need to restart the computer, hook it with the Displayport cable and try to use this custom EDID profile. It worked for me.
For example (and hoping it will help others) here are the data you need to setup a custom profile for the Dell 2408WFP :
Descriptor #0 - Timing definition:
Mode = 1920 x 1200 @ 59,950Hz
Pixel Clock............. 154,00 MHz Non-Interlaced
Horizontal Vertical
Active.................. 1920 pixels 1200 lines
Front Porch............. 48 pixels 3 lines
Sync Width.............. 32 pixels 6 lines
Back Porch.............. 80 pixels 26 lines
Blanking................ 160 pixels 35 lines
Total................... 2080 pixels 1235 lines
Scan Rate............... 74,038 kHz 59,950 Hz
Image Size.............. 519 mm 324 mm
Border.................. 0 pixels 0 lines
Sync: Digital separate with
* Negative vertical polarity
* Positive horizontal polarity
2) Of course, you can call Dell and tell them about it. They are sending me a THIRD replacement monitor for this. Be prepared when you call them : I spoke with two representative (and among them a "senior technician") who DIDN'T know what was a Displayport. They even tried to sell me the idea that 640x480 is the native resolution for Displayport. It was hilarious. Really. I got them to look it up on Wikipedia.
Case solved. Apple 1 - Dell 0.

Can't detect external monitor

I'm trying to plug a second monitor into my MacBook (13" aluminium - the MB version, not the MBP). The monitor is a 19" Iiyama, model PLE1900. I'm plugging in by DVI (DVI-D), using a Mini DisplayPort converter. The video on this laptop model is a NVIDIA GeForce 9400M.
When I plug in the monitor and turn it on, it just says "No Signal", but if I perform "Detect Displays" in the preferences, the monitor is detected, and even identified correctly.
So... I'm just stumped. Why would the lappy detect the display and then the monitor say "nothing here!"?
Is the problem due to DVI-D? The monitor also has a VGA (D-Sub) input, should I get a Mini DisplayPort adapter and try that? Obviously that an expense, so I'd rather not if I can help it.
Thanks for any replies.
Ben.

HP Phoenix computer can't detect second monitor

HI,
I have used this for a while (18 months) on one monitor and wanted to extend the desktop to a second monitor - but the system fails to detect a second monitor when it is plugged in.
It has an AMD Radeon 6850 with two DVi slots - both monitors work as I can swap them over. But neither the auto detect (HP Catalyst) or the manual detectoption show up a second monitor.
I have updated the ADM driver, restarted etc etc........ not sure what else to try. Any suggestions?
thanks
Mike

Hi MikeJeffries,
I'm sorry to hear about your problem in connecting a second monitor. Here is an article, (assuming you have Windows 8), that may be of help to you: Using Two or More Monitors with One Computer (Windows 8). Let me know if this helps at all. Best of luck to you.

MSI ATI radeon can't detect 2nd monitor

the monitor is on & working but neither Windows Hardware or the ccc detect it.
here's what I have-
Dell inspiron 530 w/ intel core(2) duo procssor 4Gb ram @ 2.20GHz
Windows Vista Home Premium sp2
MSI ATI Radeon 6450
Belkins f3006-01 vga splitter
monitors are 2 similar Gateway vga/dvi monitors.
all I want to do is extend the screen or slide pop-up windows to the 2nd screen for digital audio recording software(DAW). NO GAMING.

A closer reading of the safire 7950 Mac edition site (link above) says they want to see a Mac Pro 4,1 2009 or better.
System Requirements
Mac Pro with Mac OS X 10.7.5

Minidisplay port can't detect a monitor

I have a S230U twist. The minidisplay port used to work with my VGA adaptor to project to a second monitor and a projecter, but recently it failed to work. I think it might be a hardware issue, but would like to try troubleshoot myself first. Could anyone suggest some methods to troubleshoot? The operating system is Windows 8.1.
Thanks. I appreciate your help.

It won't let me do that. When I go to the Network window of my System Preferences, it says Location: Automatic, and it won't let me click on New Location or on Edit Locations - they are pale grey.
Also, it says Show Network Port Configurations and it gives me six: Internal Modem, Airport, Bluetooth, Built-in Ethernet, Built-in Firewire, VPN (L2TP) whatever that is, and Ethernet Adaptor (en2), and I don't know if that is the cable from my friend's router or the new stick adaptor I bought (it doesn't change, whichever I have plugged in), but all these are also pale grey and I can't click on them or on the boxes marked New Rename Delete or Duplicate.
Also the stick adaptor I bought is not showing up in my Finder window as an attached device - shouldn't it? This means I can't eject it safely when I want to. There are no instructions enclosed with it or on the manufacturer's website.
When I click on Network Status with the cable attached, it says I am currently connected to the Internet via built-in Ethernet with the IP address 192.168.0.112 so I guess built-in Ethernet must be the cable. So if the Ethernet Adaptor (en2) is the adaptor stick, maybe it isn't being recognized by my computer because it is on channel 13?

[SOLVED] m_sensors can't detect the chipset so I can't set up my fans

I have overheating problems with my Latitude E5520
(to be exact: http://www.dell.com/support/troubleshoo … ag/50GBMQ1)
so I wanted to see what my fans are doing;
I went through https://wiki.archlinux.org/index.php/Lm_sensors
and then through https://wiki.archlinux.org/index.php/Fan_Speed_Control
and I had to stop at "The first line of the sensors output is the chipset your motherboard uses to read the speeds, temperatures, and voltages.".
My output:
[sms@sms ~]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +25.0°C (crit = +107.0°C)
coretemp-isa-0000

is telling me nothing: I bet my chipset is not called "coretemp-isa-0000"...

I realize it doesn't seem to mean anything, but my sensor gives the same name and I'm running an i7 sandybridge, so I don't think it is a mistake. From what I've read, it is just listing the sensors it finds, starting with zero. Subsequent sensors, if they were found, would be listed coretemp-isa-0001, coretemp-isa-0002, etc.

Dual Monitor on Hp Pro 3400 : can't detect the 2nd

Hi,
I have a problem with the computer of a friend.
Here's the plan.
He has a HP Pro 3400 with Intel HD 2000 Graphics, 2 VGA monitors, 1 VGA and 1 DVI(-D ?) output.
He has a VGA cable, a DVI cable and a DVI-to-VGA adapter.
And here's the problem.
If he connects the VGA monitor using VGA cable : it works.
If he connects the other VGA monitor using VGA cable: it works
* blah * using DVI cable + adapter, works for both monitors.
... if he connects the 2 at the same time, the VGA > VGA works and the DVI > adapt > VGA can't be detected (at all).
It's not that he can't use 2 monitors, the second one just CAN'T be detected when he uses the 2 ..
Can you help me figure this out ?
Thanks.

You have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the monitor. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the monitor and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the monitor your Menu Bar will automatically change back to the MacBook.

New monitor can not detect signal from new referb pc

Monitor is a new flat screen,  model 2310m full HD with  vga, hdmi, and dvi-d connectors and boot up CD which includes pdf manual and video drivers etc..
        PC is a referb Pavilion M9200t first time started since referb with a G-Force GT graphics card (1 gigabite) and dual DVI-D connections. No VGA or HDMI out. OS is vista ultimate that I will probably update to windows 7 if I ever get it set up. Monitor does not get a signal from new PC with DVI-D cable or a VGA cable with an adapter. Monitor works fine with my old XP PC after installing drivers and using the vga cable. New PC has no VGA out, so I bought a VGA to DVI-D adapter thinking that it would have proper drivers for a VGA monitor with no success. I also tried new PC on my old monitor with the DVI-D adapter on the VGA cable and that didn't work either. I can't do a first run setup without a monitor and the monitor won't work without a signal.
       I bought the PC from a friend who decieded to buy a laptop instead and had never started it. He bought it from someone who was selling referbs on E-bay and messed up and accidently started the warranty period or so they say.
        Also when I plug the PC in the fan starts and continues running till I do a hard shutdown, that is holding start button down till the PC shuts off. If I unplug and replug the computer it starts again without pushing start button. Does anyone think it is the graphics card issue or maybe power supply, or just not booting at all?  Any ideas would be greatly appreciated.------Thanks in advance.----Larry
