• Default prolog for all ZSH scripts?

  - by Igor Spasic

  I have a file that contains several helper functions, meant to be used only in other ZSH scripts. I do not want them to be loaded with my profile. To make these functions available in my script, I would need to source this file. Is it somehow possible to have automatic prolog script (or pre-script) loaded before all my ZSH scripts? My current idea is to alias -s zsh extension to custom function that those all this for me: concatenate prolog file and current script calls zsh with such modified input but for now I am somehow not able to do this (haven't sleep for almost a day). Please, does anyone have a working solution?

• How do I remove the "Shutdown" menu entry from Gnome's system menu?

  - by nathan

  We have a lab with multiple RedHat EL5 machines running the Gnome desktop environment. When developers are done using the machine sometimes they miss the logout button and click the Shutdown button by mistake (easy to do, I've done it myself). Needless to say, for those remoted into the lab it's sometimes devastating. Is there a way to remove the Shutdown entry for all users from the Gnome menu? Note: I do not mean Shutdown on the greeter, but the Shutdown button on the menu drop down that is next to logout, sleep, etc.

• CPU fan twitching phase leds blinking - computer won't boot

  - by SooX

  I have a big problem that I got today. Yesterday computer was "on" normally, I went to sleep without shutting it down. When I woke up, I heard a strange sound and was unable to bring it up from hibernate. I unplugged the PSU. When I plugged the PSU back in, the sound came back. When I opened the case, I saw the fan "twitching" like it is about to start and fan LEDs were blinking. Also, motherboard LEDs were blinking in the same pattern - the first green one has more of luminosity then others. When I cut down the power with 0/1 button on PSU, the fans continue to make sounds like the machine is trying to boot before the capacitors run out and the power dies. Does anyone have a clue what to do? I tried disassembling everything but that doesn't work. I will try with friend's PSU later today.

• Dell laptop doesn't wake from hibernation after installing Windows 8.1

  - by Mike Cole

  My laptop worked flawlessly before upgrade to Windows 8.1 from 8. Now when I close the lid of my laptop and it goes into hibernation, it will not wake again. The LED lights seem to work properly but I don't get any video. I have to hold the power key to turn off then turn it back on again. It wakes from sleep properly. All Windows Updates have been installed. There are 2-3 items in the Device Manager that do not have compatible 8.1 drivers, but I believe those are security related items like fingerprint scanner.

• Understanding the Linux boot process, subsystem initialization, & udev rules?

  - by quack quixote

  I'm creating UDEV rules for automounting external drives on a headless server, much in the same way as Gnome-VFS does automounting during a user session. I'm concerned with the rule's behavior at boot-time. There's a good chance one of these drives will be connected during a boot, and I'd prefer any connected drives get mounted in the right place. The drives might be either USB or Firewire, and they are mounted from a shell script fired off by UDEV on detecting an "add". Here are my questions: When UDEV runs the mount for these devices at boot, will the system be ready to mount it? Or will the script get triggered too early? If it's too early, what's a good way for a script to tell that the system isn't ready yet (so sleep a while before checking again)? The UDEV rule matches ACTION=="add". Does this event even fire at system boot?

• Intel motherboard drops HDMI output after Windows boots

  - by Nick

  I have an Intel motherboard (DH67CL) that uses Intel HD 3000 video. It has two video output ports: HDMI and DVI. Both my monitors are DVI, so I have two cables: a DVI-DVI and an HDMI-DVI. If I plug a monitor into just one of these ports, things work fine. But if I plug monitors into each of the ports, the system startup screens show on both monitors, along with the "Starting Windows..." screen, but as soon as the system boots into Windows, the HDMI-connected monitor goes to sleep. When I use the Intel video control panel, the HDMI-connected monitor is not detected. How do I get a dual-monitor setup to work?

• BSOD on windows 7 with SSD during boot after improper shutdown

  - by Bob

  I have a BSOD on windows 7 with SSD during boot after improper shutdown (while windows animation logo is moving). The computer restart imediatly after BSOD, and windows proposes to launch startup repair (if i do it, it takes +-5min and fixes the problem : computer starts normally). However, after any new improper shutdown, i got the same problem. Remarks: If i unplug, re-plug the SSD whyle system is shutdown, i have the same problem. If i reproduce the situation with old HDD, i havn't the problem Previously, i had a different problem: BSOD when waking up after sleep, which was fixed by installing drivers (ethernet, usb, graphic card) I have made ram chech and ssd check and found no problems Starting with safe mode after improper shutdown causes a BSOD at loading of classpnp.sys Configuration: System: HP compaq 8510p SSD: OCZ vertex-2 2.5 Boot options: SATA native mode - Enable, HDD transalation mode - LBA-assisted

  - by Alex

  I want to run a shell script over the weekend, but I wanna make sure if the terminal loses the connection, my script won't be terminated. I use nohup for the whole script invokation, but I also want to execute some portion of my shell script in a way that if someone closes my terminal, my script runs on the background still. Here is a simple example : #!/bin/bash echo "Start the trap" trap " " HUP echo "Sleeping for 60 Seconds" sleep 60 echo "I just woke up!" Please suggest what I should do ?

• Dell U271 monitor DisplayPort suddenly not working

  - by Amir Latif

  My new(ish) Dell U271 took a bit of a knock and it now suddenly doesn't recognise the Macbook plugged into it via DisplayPort - this had been working great for several months up until now. When I "Scan Sources", it doesn't find anything on DisplayPort. However, one suspicious behaviour leads me to think all might not be lost. When the Mac is woken from sleep, this used to kick the monitor in (as an monitor would) and while it no longer does that, the light on the monitor does go from standby orange to blue briefly, then the monitor says it's going into "power save" mode. It seems like it gets some kinda signal. Any ideas on how I can diagnose the problem? I'm trying to find another mac but no one near me has one ...

• Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedor

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Screen flickers after resuming from hibernate with Intel GMA 3600 (Acer D270 with Intel N2600)

  - by Cameron

  Fresh system install, with correct display driver from Intel (8.14.8.1065). Clicking "Update driver" merely results in a message saying the driver was already up-to-date. After resuming from hibernate the entire screen flickers. This is especially noticeable while using IE9 (which has hardware acceleration enabled by default) on Google maps, in particular while typing in an address in the map search field (the flickering is much worse under these circumstances). Note that sleep worked fine, only hibernate causes this issue. Restarting "fixes" the problem temporarily until the next hibernate-resume. Aero is enabled. This is on Windows 7 (Pro) 32-bit, on an Acer Aspire One D270-1998, with the Intel N2600 (which has the Intel GMA 3600 built-in).

• Keeping rackspace vserver alive

  - by mit

  It appears to me that rackspace somehow freezes cloud VMs after some idle time. This means the first page request to a php page takes much longer to respond than the subsequent requests. I am actually querying a machine with wget from a different host now to keep it "alive". But I wonder what frequency would be necessary. Does anyone know the time period after which they send a VM to "sleep"? I guess it would be some minutes. EDIT: There is no caching involved on the php site. It just recently moved from another vhost and there was never such latency on the first request.

• How to Shutdown PC by Pressing Power Button

  - by AgA

  I always Hibernate my PC. Sometimes when I boot, it does not recognize the mouse/keyboard or any USB devices. I've also setup it to go in sleep in 5 minutes. In that case I can't restart the PC so that USB starts working. When I press the Power button then it starts shutdown but asks confirmation twice one is for shutdown by force confirmation and then there is one more. When my USB is disabled I can't input these options. So I switch off the power. What I want is that upon pressing Power Button it should at once start shutdown without asking any more confirmations System details: Win-7 Home Premium 64 bit Intel i3 530 Asus P montherboard EDIT: It is Desktop PC

• USB Wireless keyboards not registering Ctrl Alt Delete when computer boots

  - by Donovan

  I've recently installed a new PC at work. Its a Dell Optiplex 9010. I bought a USB wireless keyboard and mouse from Dell and subsequently from Logitech to use with this PC. The Dell keyboard is a model KM632 and the logitech is an mk260. Both units work properly and have decent range. The issue is when the PC boots they keyboard (neither model) will register a Ctrl+Alt+Delete to the PC. I can say for sure the keyboards are still functional as the media keys will still produce a result (notably the sleep key on the mk260). My gut reaction is I'm dealing with an issue in the PC or Windows. I'm not sure where to start though. If I unplug and reinsert the USB dongle both units will work. Also, I don't use both they keyboards at the same time I bought the Logitech fearing the Dell unit was bad. Any ideas would be appreciated.

• Ubuntu PowerEdge T110

  - by Josh

  I just got a Dell PowerEdge T110 server. I moved the boot order to CD - HDD - NIC, then installed Ubuntu 10.10, Desktop Ed. I chose install alongside other OS (even though there was none), then chose use entire partition. It showed that Ubuntu would use 160 of the 160 available GB. It installed, updated (while installing), then said, need to eject and restart, as usual. It restarted, but to a blank screen. No output whatsoever. Not even BIOS. Just blank. The monitor isn't even woken from sleep. Power cycled, still doing it. Tested the monitor with a laptop, and it is fine. What on earth is going on here?

• Laptop freezes on Wireless Mouse Adapter attach/detach

  - by Sergiy Byelozyorov

  I am using Microsoft Wireless Notebook Optical Mouse 3000 with Toshiba Satellite Pro P300-1CG. Recently I have installed Windows 7 64-bit. Now once in a while when I plug-in or plug-out wireless mouse adapter, the computer freezes (image stays on the screen, but the computer is not responsive). I have noticed that it mostly happens after I recover my computer from sleep mode. To continue using laptop I have to shut it down by pressing and holding power button for 7 seconds and then booting it up again. What can be done to prevent this?

• I want to play one podcast only on iTouch, but they play in series one after the other.

  - by Eddy

  I download multiple podcasts from one source, eg, five episodes of Naked Scientists. I want to listen to one only, but when the first finishes it automatically goes to the second, and third etc. I want to listen to just one episode at a time and have the iTouch turn off when it is finished (this is a sleep-aid for my insomnia...I don't want it playing all night !) A "Genius" suggested making playlists, but although you can make a podcast playlist, it does NOT sync. Please help. thanks, Ed3339

• PC will be turned off in safe mode

  - by abbasi

  I wanted to scan a Dell inspiron N5010 laptop in safe mode. When I took it to the safe mode environment and ran the AV to scan, after some while the PC went out! The power options menu options (when plug is in) are as follows: Screensaver after 4 mins. Dim to display after 10 mins. Turn off display after 15 mins. Hard disk, sleep and hibernate are all off (set to never). I tested the machine without scanning it, i.e, went to the safe mode and waited to see what occurs after time elapsing. By observations so far (because I can apply more tests to determine that where the problem exactly is), the problem is when the machine is in safe mode and is doing something (in current case, scanning). What do you think? Why it goes out in this situation please? Thanks in advance.

• How do you make the computer locked when the monitor is turned off but power not off in Windows Vista?

  - by Anon

  I have a power management setting (set up through the Control Panel) that turns the monitor off after 5 minutes of idling but keeps the power on all time, if the laptop is connected to power. Under this setting, however, the computer doesn't lock itself and becomes vulnerable to any passerby's attempt to log in if I'm not around. Is there any way to force lock in this situation? (I can force lock if I have the laptop go sleep, but for immediate access I'd like to keep the power on when the laptop is connected to power.)

  - by Juan Zamudio

  Hi all, this is the situation, this is a Dell Optiplex 755, I recently upgraded it to Windows 7 64 bits, it had Windows XP SP3 previously, on XP I never had a problem hibernating the PC, now with Windows 7 64 every time I hibernate the PC it wakes it self after 5 or so seconds. Here are the steps I already tried: On Windows 7 I enabled the hibernation following this steps In the MoBo the sleep settings are on S3 In the Mobo I disable remote wake ups I have disabled the remote wake up in the NIC When I run the lastwake command I get unknown device or something like that I already disable the wake timers on Windows I have the latest drivers from Intel, but I just found out that in the device Manager I get a warning sign on the "Intel AMT SOL (COM3)" device saying that it failed and windows stopped the device, I reinstalled the Intel drivers but nothing changed. The only thing that I haven't touch is Intel ME in the MoBo but I don't if that could help and what settings are correct. Thanks for you help.
