Can I use apcupsd to monitor my smart-ups 2200 without it being connected to a server? I have set the TCP info on the APC and can telnet into it, but I'm kinda confused by what I've been reading in the apcupsd documentation.
If someone can tell me about there experience doing this and best practice that would be awesome.
i done desktop config in ubuntu server 11.04 and connected via tightvnc,uvnc and in remote desktop viewer from another ubuntu machine also. I am not able to access(connect) the server in GUI mode(when monitor is removed) but i putty is working fine in cmd line.

They seem to just connect and i don't want to have to change the password particularly because that involves changing it on multiple devices.

I saw a post about this elsewhere and downloaded some firmware drives from [URL] and installed then. But, I'm really out of my league when it comes to this kind of stuff.
Just installed ubuntu 10.04 on my Dell inspiron 1525 laptop. Everything got installed right, and I elected to select the sta driver rather than the B43 driver. After restarting, the b43 option disappeared. The wireless said it connected, but when i went to firefox it wouldn't load and said server not found. My wireless card is a bcm4312. Any ideas as to why this is not working?
View 7 Replies View Relatedeasy I managed to install Oracle, JBoss and other software, connected to it via VNC. Once finished I decided to move the box to far corner and work with it via putty and vnc. But then problems with vnc started. Whenever I tried to connect via vnc I got background screen with cross cursor and then it stuck, no login screen. I spent a lot of time trying to fix it. I red many forums and this one in partucular : VNC is not working - openSUSE Forums Nothing helped. I have noticed that vnc doesn't work if monitor not physically connected to the box.
Once monitor connected, even if monitor is not powered up, vnc resumed to work correctly. But it looked senseless for me, what a point to have Linux box controlled via vnc if I still have to connect monitor, it drove me crazy !Today I have found a solution and want to share with you. It is not my idea I have found it here :K7V FreeNAS system won't start without a monitor. - alt.comp.periphs.mainboard.asus | Google GroupsThe idea is to create "fake monitor" which cheats graphic card, makes it think a monitor is connected. I have bought a VGA connector then:
Connect 75 ohm resistor from pin 1 to pin 6
Connect 75 ohm resistor from pin 2 to pin 7
Connect 75 ohm resistor from pin 3 to pin 8

School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.
So here is what works:
1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.
2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).
3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.
What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:
Code:
The system is going down for halt NOW!
acpid: exiting
init: cron main process (1011) killed by TERM signal.
init: tty1 main process (1365) killed by TERM signal.
[code]...
If I try ctrl-alt-del at this stage, it says:
"init: rc main process (3030) killed by TERM signal"
"Checking for running unattended-upgrades: "
And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.
How can I detect when an external monitor is connected in linux? I need to run various scripts to set up my workspace. Is there some clever way to kick off a script when the monitor state has changed? I'm using the Nvidia display driver.
View 3 Replies View RelatedIve been wondering about an alternative method for checking to see if an external monitor is connected.
Currently I am using:
Code:
#!/bin/bash
EXTERN=VGA1
if $(xrandr --prop |grep -q "$EXTERN connected");then
echo -e "$(echo $EXTERN | tr -d [0-9]) is e[1;32mconnectede[0m"
else

So, what I am asking is, is there a way to ignore/over-ride compiz's texture size check, a different way to query xrandr, or is there a completely different method I can go about checking if an external monitor is connected?
I have connected to the VGA output of my laptop a 19" monitor. I setted in Ubuntu the resolution for that monitor to 1280x1024.
Two days ago i connected the laptop to a projector. When Ubuntu detected the projector it ask me for my user password to change "i dont know what".
After using the projector I have connected the laptop to the 19" monitor again. Now I can not set the resolution for the monitor to 1280x1024 (that resolution doesn't appear in the list)....
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 beating my brains out trying to get Lucid Lynx connected to an SME Server 7.4 to automatically mount windows shares. The winbind stuff seems to work okay after I installed a restart script in /etc/network/if-up.d (kudos to OsGnuru & bobpaul for that) There is a short wait on network up before winbind can validate but that is not a show stopper. I have looked at (what I think) is the correct log for pam_mount and it seems to be running through to the end process okay. It looks like it is either not reading the pam_mount.conf.xml file or I have not configured it correctly as it just reports "No Volumes to Mount". I have appended the log file, pam_mount auth, password, session & common conf files as well as the pam_mount.conf.xml file for review.

I am running 11.04 on a new Gateway with 8 gigs of ram. It is a solo installation. The monitor is connected via an HDMI cable. Everything was great (installation running smoothly for over a month) until last night. I just installed a netgear router and was setting it up with the system to try to get Stanza on my IPAD to connect to Calibre. Anyway, i suffered a severe freeze up warranting a hard boot. I could see the drive working, ancillary drives lit up, keyboard lit up so I know the system is working. The monitor did not come on, It shows a yellow light indication no signal. It is a 28" Hansspree. I tested the monitor by hooking it to a laptop. The monitor is fine. I cannot see anything on the screen so I can't boot to repair mode or use a CD. There is no signal.
View 1 Replies View RelatedI 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 have 3 monitors and two video cards. In my ATI HD 6750 I have the DVI going to monitor one and the VGA for that card going to monitor 2.

The second card (Nvidia GT218) I have the DVI connection going to monitor three Monitor one and two for the ATI work perfect but I cannot get monitor three which is connected to the nvidia gt218 to work properly. 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.
I'm trying to get my secondary display (DVI-Out) working on a laptop (built-in monitor & external display) and I'm afraid I made quite the mess of it installing the proprietary driver only to learn that my old ATI card is no longer supported and having to clean that up and reinstall the original distro driver!Anyways, I reverted back to the open source driver and all is ok. That is until I reboot. If I reboot with the DVI display connected then both displays are brought up in 640x480 res and look terrible.
What do I have to do to be able to leave my DVI display connected when I start up the machine and get it to render the way it does when I plug in the display after the machine is running?I suspect I need to create an xorg.conf file but these fancy modern Linuxes these days don't come with one (or maybe they no longer need it anymore).
Is there a way with apcupsd to get current ups status? Like battery percentage left, that kind of thing? I've been struggling trying to get it to work with an old UPS, and after it just made the UPS shut off (causing the server to go down) I decided to just try with my UPS upstairs instead (just wired the management through my patch panel for now). I got it going to the point where it detects a power outage, but is there not a way I can query the status to get more info?
I have it setup to eventually shut down but it would be nice to get status such as how long I have before it does so, and so on. There's a GUI utility that I downloaded but it just says connection refused.

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
