Two days ago I switch from Arch Linux to CentOS. Everything is working as it should; except that I can't get my second monitor to work. I use two monitors (VGA: LG-W2241S, DVI: ACER-AL1906) connected to one video card (GeForce 7300 SE).
[Code]....
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 Thinkpad E420, Fedora 15
how can i view/monitor what a user is typing in other terminals in centos?
View 1 Replies View RelatedI called the manufactures up and they said to call my computer manufacturer to set up the monitor. They said to set it up so that it is the second monitor and adjust the resolution to 640x480. Then I can un-connect my first monitor and use this one. I am using the nvidia driver for my nvidia graphics card. I am unsure how to set it[URL]

View 14 Replies View RelatedI'm having this problem with a older ibm thinkcentre with some:00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
video controller in it.
The problem is the monitor connected has to stay on all the time, but something keeps shutting down the video card then the machine has been idle for some time, and the monitor goes "No video signal" until someone touches the mouse or keyboard.
The system is the newst updated 9.10, and ive set "Put monitor to sleep = never" in the power management settings. Ive also disabled the screen saver.
Now, i dont think its Xorg that shut the video card down, i believe its the framebuffer (or kernel console or whatever its called). If i jump to the console with ctrl-alt + F1, log in and turn off Xorg with lets say sudo service gdm stop, the video card still turns off after like 15-20 minutes.
Other things ive tried:
completely disabling framebuffer in the grub configuration (with vga=normal and nofb and even combining both, this however doesn't really disable the high resolution framebuffer at all. Its still on now matter how much i try to disable it..hmm (and the grub settings is used by grub as I'm able to set nosplash witch is effective))
and the last thing I've tried was setterm -powersave off, no luck there.
Before thinking it may be the console doing the video poweroff, I tried disabling DPMS in Xorg config, (and disabling it with xset) this dosent help, although i'm able to turn on the video signal again from a ssh session with xset -dpms -display :0.0 or xset dpms force on -display :0.0. However after some idletime the video signal shutsdown again.
I'm setting up a headless unit with Xubuntu (lucid), VirtualBox and Vino. It works fine except that when I unplug the monitor and reboot I can't connect via VNC. I can ssh in just fine. If I try to plug in a monitor to see the display I get no signal. My assumption is that Ubuntu detected no monitor and decided to ask me something or act differently.

I am on kubuntu 9.10 x86_64
I just got my new video card: nvidia 9500 GT to setup dual monitors.
The video card has 2 dvi output to support dual monitors
Monitor 1 is connect to dvi
Monitor 2 is connect to dvi using a vga adaptor
I can't seem to get dual monitor to work?
From system settings -> monitor, i see 2 vid outputs one is DVI0, the other is VGA2. what's odd is i can set up different screen resolution for each monitor, but I only see one desktop, both monitors show the same desktop.
How do i get each monitor to show it's own desktop?
Before ubuntu can even boot I get this on my monitor Out of range set to 1280x1080 60Hz I get that a grub. I'm not even sure if ubuntu can even boot because my monitor won't let me see anything. I'm using the driver off the nvidia website, not the stock one that came with ubuntu.
View 1 Replies View RelatedI am almost tempted to go back to an old slackware to try this. Anyway, I found a circuit (with just a few resistors) that allows vga output to go to composite input. To my amazement it actually works and it is very clear, but has a double screen. I am told, to fix it you need to change the horizontal sync and or refresh rate for the card. (17 instead of 35). How would I do this in xorg.conf?

I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.
1) The built in Realtek RTL8139 configured as eth0.
2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.
I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.
When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?
I have just upgraded from Fedora 11 to Fedora 13 and now can't get my two monitors working as a single "screen" (it worked under F11). I have a GeForce video card with two monitor outputs

I then edit the xorg.conf to change the driver from nouveau to nv and I can start X and the LCD displays the desktop at a resolution of 1680x1050 (good) but the CRT just displays random blocks of colour. At this point I also get a kernel crash - see dmesg output attached, but the system is then OK to use. I have tried editing the xorg.conf to add a second monitor and a virtual screen resolution to match the two monitors (1024x768 + 1680x1050) combined (2704x1050) but still only the LCD monitor works, but with the virtual desktop that can be nudged around with the mouse. I would like to get back to using both monitors with a virtual screen across the two monitors.
I am using Open Suse 11.2 on my HP DV6 notebook. I am connecting my television to the notebook with a HDMI cable and the television is unable to find any signal. Am I missing anything here? Shouldn't it be simply connecting the HDMI cable finding the source channel on the television and then I get sound and picture..
View 3 Replies View RelatedWhen you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.
I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?
I have a Intel DQ35JOE motherboard with integrated video (DVI and VGA). I've been running Ubuntu 8.10 for at least a year with both monitors working fine. One is a Hanns-G 27.5 inch, the other (VGA) is an older AOC 19". They were both plugged into the motherboard video plugs (it had both), and they worked side-by-side (not mirrored) just fine on 8.10.Last night I decided to go ahead and take the plunge and upgrade to the latest, because I run 9.10 on my laptop and love a lot of the new stuff. The reason I hadn't upgraded was because I feared the potential problems - which I ran into head-on this time.
Upgrade to 9.04 seemed to go fine. Then I immediately did the upgrade to 9.10. Unfortunately, my screens came up upside down and backwards. And the mouse moved the wrong way. And to click on something in the top left of the screen, I had to have my mouse on the bottom right of the screen.Well, I also received a warning that my primary hard disk was failing. So, I decided to just do a clean install of 9.10 on a new disk that I had handy - hoping it would be better if it was a clean install rather than an upgrade.
Now I can't get dual monitor to work at all, and Ubuntu seems to not recognize my monitors. If I just plug one monitor in, it works. But it won't let me adjust resolution above 1280x1024 (my big one is 1920x1200). And it says "unknown" instead of identifying the monitor.Also - at one point both monitors were appearing (but "unknown"), but mirrored, and whenever I uncheck "mirror screens" and click apply, the screen just goes black with a frozen cursor - and I can't even do CTRL-ALT-F6 to get to a terminal - it just freezes the whole computer.
I am experiencing a strange problem. I have two vga monitors and a ATI Radeon HD 3300 embedded on my motherboard. My embedded graphics card has a vga and dvi output. When I plug my monitors in (one uses a dvi to vga dongle) only the one with out the dongle gets a signal. I can swap which monitor uses the dongle and still only the one that does not use the dongle gets a signal (both monitors work, only if they are not using a dongle). Both Ubuntu and Windows are having trouble displaying video, but no trouble detecting the monitors (display settings show both monitors but do not tell me good resolutions for them). My friend has a different dvi to vga dongle, his only has about half of the dvi pins while mine has all the pins. Could the problem be that my dongle has all the dvi pins

Both v-cards are ATI, supposedly working from the same drivers. I don't mind using a different linux distribution, if it makes matters any easier.
Last night I was able to set up my server so that I can just connect vnc. I even was able to be connected at the log on screen so I could select which user I wanted to log in at. For some reason today, I have to have the monitor plugged in all the until the logon screen comes up before vnc will connect. Once the logon screen is up, I then can connect via vnc & select which user I want to logon as. It's odd because it worked last nigh, but today - Nope nada, it doesn't work & I can't explain why. I did clean up - Removing some applications I don't need on my server. (I'm hoping that isn't the problem) It's odd as well because I don't have to be logged on as a user to connect via vnc, I just have to wait until the logon screen is available...Then I can unplugged the monitor & logon.

I have recently installed Ubuntu 11.04 on my PC with these configuration:CPU: AMD Athlon 7750 Black EditionRAM: 2GB 1066 MHzVGA: ATI Radeon HD 3200 (on AMD 780G)After I installed Natty Narwhal I felt that my CPU runs at the highest clock all the time (2.7GHz), even if I don't have any program run. I tried all settings for AMD Cool'n'Quiet from mainboard BIOS, but nothing's changed. I installed "CPU Frequency Scaling Monitor" to manually change CPU clock. It recognizes two clock for my CPU, 2.7GHz and 1.35Ghz plus 4 other options; Conservative, Ondemand, Performance and Powersave but the CPU indicator doesn't change on every option!

I tried editing my own xorg.conf file but that did not work, I have a windows 7 install on this box that works properly. I cant seem to make this work with the third monitor and the nvidia video card.
9.10 Problem with Graphics/3D and other I have a Thinkpad T42, 1.7GHz, 1Gb Ram and a Radeon 7500 Graphics card. Everything that I am having trouble with works just fine in Ubuntu 9.04(except for the sound). There are two problems that I think are linked or really the same. First off, When I turn off Compiz(Compiz works by default) then gnome-system-monitor does not work properly. At least the graphics side of it; the window appears black with random lines running threw it. The same thing will happen to Gnome-do if Compiz is off.
The second problem is getting 3d support to work. I installed and tried to run blender and I got this from the terminal:
[Code]...
Then it ether does not open or the computer locks up completely and I have to force a shutdown. Which ever one it does I do not get my desired results. When trying to do chess in 3D it tells that I have 'No Python OpenGL support'. So I install the python-opengl package from the repositories; the program now just errors on start and I had to uninstall python-opengl to get Chess to work again. I have tried all this with Compiz on and off with the same results. Anyways thats about it, unless somebody knows how to setup the sound so a program won't lock it from other, then thats all I am having trouble with.

I have installed Ubuntu 9.10 on my laptop Lenovo T60. The problem is i can't make extended monitor in that way: laptop 1024x768 and Monitor LG L1952HQ 1280x1024. If i make this configuration, screens appear black and i can't go back without restarting. Presently system support only: laptop 1024x768 and LG L1952HQ 800x600. This configuration (laptop 1024x768 and LG L1952HQ 1280x1024) worked well previously with the same ubuntu 9.10 before reinstallation. I guess i should reinstall ore change to other video drivers? The refresh rate is set on 60 Hz.

This will be a little long (having read Phil's 'how to ask questions' FAQ). I'm trying to get OpenVPN working between my CentOS server and some Windoze laptops running XP. There seems to be plenty of sample
config files available, but to date, none of them have worked for me. Pulling out my trusty Wireshark, I've found some clues,
BACKGROUND:
My local subnet (NAT'ed by my gateway router) is 192.168.52.x. My router has been configured with a conduit (port-forward) for port 1194 (the standard OpenVPN port), which points towards my CentOS server.The CentOS server is .52.112, and the supplicant is .52.110. I have tried the lient both inside and outside my local subnet, with no difference in events or outcomes.
