• Shut Down took way too long because of "Background Programs"

  - by Christopher Chipps

  I tried shutting my desktop PC (with Windows7) down but after several attempts (like 4 or 5) at Start -- Shut Down, the GUI was still there and it was not shutting down. I didn't think there were any programs running when I pressed Shut Down, so I went into the taskbar (Ctrl + Alt + Del) to check out the processes. Once I did that, a screen appeared with a message stating that there are "background programs" still running and it gave me an option to "Force Shut Down" which I pressed and it shut down normally. Does anyone know why this would happen?

• Unable to click on tabs in Firefox unless I press Command-Q

  - by Philip

  Why does clicking on tabs in Firefox sometimes fail until I hit cmd-Q, and then why does that not quit but instead make clicking on the tabs work, and how do I stop that behavior? I'm running Firefox 3.5.5 on Mac OS X 10.5 and this has been happening for a while (with previous versions of FF as well). I can't forcibly reproduce the behavior, but every now and then (few days?) I just can't click on tabs or on the x's to close the tabs. I can still ctrl-tab between tabs, though. But if I press cmd-Q, instead of quitting, Firefox seems to seize for a second and then I can click on tabs and click to close them just fine. No clue why this is happening or how to stop it. And I do have tons of extensions installed, so it's plausible one of them is the problem..... Thanks.

• Chrome browser caching

  - by Kyle B.

  I do a lot of development on my local machine and would like to start using Chrome, however I cannot seem to do a hard-refresh (ctrl+f5) or any other key combination to get my browser to forcibly refresh all content @ http://localhost. I change projects frequently in IIS and this presents a problem because I see stylesheet and image data from my previous project with no way to get this page to reload without forcibly dumping all cache data from the settings menu. Is there another key combination I am missing, or is there a place I can (on a site by site basis) turn off caching? I prefer not to have to clear out my temporary files in the browser settings as I switch projects frequently. Thanks, Kyle

• Strange messages on new Dell Workstation during bootup

  - by dan99t

  I recently installed Windows 7 Ultimate on a new Dell T-7500 Workstation, and am seeing some strange messages on the screen: Dell SAS 6 Host Bus Adapter BIOS MPTBIOS 6.22.03.00 ( 2008.08.06 ) Initializing….. Press Ctrl – C to run SAS Configuration Utility Searching for Devices at HBA 0….. Dell MPT Boot ROM Successfully installed Then it loads Windows 7. All of above happens on its own, I don't touch anything. So what is going on & what do I have to do get rid off those initializing commands ? I have never had this happen to any previously owned Dell systems. Also I haven't installed any drivers yet but Sound, Video & Internet does work. Do I need to install any additional drivers?

• Is there a way to launch a command within a proper zsh shell ?

  - by Wam

  I'm not really clear with my question here, let me rephrase it : I've setup a launch_workspace.sh to launch directly tmux with 5 different commands loaded. Here is my current content : #!/bin/sh tmux new-session -d -s scube -n 'vim' "vim" tmux new-window -t scube:2 -n 'server' "$SHELL -c 'script/rails server'" tmux new-window -t scube:3 -n 'yard' "$SHELL -c 'bundle exec yard server --gems'" tmux new-window -t scube:4 -n 'spork' "$SHELL -c 'bundle exec guard'" tmux new-window -t scube:5 -n 'autotest' "$SHELL -c 'bundle exec autotest'" tmux new-window -t scube:5 -n 'shell' "$SHELL" tmux select-window -t scube:1 tmux -2 attach-session -t scube Problem is : my zsh ($SHELL beeing zsh) launches said commands, but when I Ctrl+C any of these, it closes the full zsh (hence my tmux window) and not just return to a proper zsh prompt. Is there a way to have said behavior, to launch zsh with a command and return to a zsh prompt when the command fails ? Cheers

• How to enter into BusyBox when booting?

  - by ???

  I have occasionally installed cloud-init package in Ubuntu, which blocks me from booting. Neither recovery mode works. Because cloud-init installed some upstart job configuration. So I want to enter into busybox to remove /etc/init/cloud-init*.conf, but it seems like no way to do it. I can press Ctrl+Alt+SysRq which brings on a rough hack menu, but there is no busybox option. So is it possible? My CDROM is broken so I can't use Live CD too.

• How to send Windows key over VNC to Linux from Windows?

  - by MJBoa

  Alright, so I'm running Linux with AwesomeWM on my home machine. I'm running x11vnc on that machine and I want to connect to it from a windows machine. So it suffices to say that I need the Windows key for my home machine to function. I really like TightVNC, but I have found that only RealVNC is able to send the Windows key presses that I need. My problem is that RealVNC is sorely lacking customization and I feel it's inferior to TightVNC and unusable. I know that Ctrl-Esc sends the windows key press in Tight but then I can't use it as a modifier key. Useless. Anyone have any ideas? I don't think it's a server issue since I've tried Tightvnc server on the linux machine and it still doesn't work, at least in TightVNC. It works with Real anyway. Oh and UltraVNC doesn't work either.

• Right-button drag-drop function in Gnome

  - by HorusKol

  While I don't really miss the annoyances that go with working on Windows, one thing I do wish I had in Gnome is the ability to hold the right-mouse button down on a file and drag it to get the context menu asking if I want to move or copy the file. I realise the default tries to be sensible (like in Windows - defaults to move if on the same volume, or copy if on different) and that it can be overridden with <ctrl> or <shift> - but i'm still used to the right-mouse drag option and keep getting frustrated when it doesn't work...

• How can I tell whether an interrupted rm -r removed any files?

  - by Jake Petroules

  I installed sshfs a Linux box and then mounted my Mac home directory. In the middle of troubleshooting a configuration issue, I did an ls -l on the mount directory (as normal user), receiving: total 0 d????????? ? ? ? ? ? sl I then ran sudo rm -r on that directory but pressed Ctrl+C to terminate it immediately before it (looks) like the command did anything. I notice no files missing but I want to be sure - is there a way I can somehow inspect the filesystem log on my Mac to see if any files were actually removed?

• Is the view history in Firefox 3.6.3 broken or is there an "undocumented feature"?

  - by Lirik

  Firefox View History Before Firefox 3.6.3 when I clicked Ctrl+H it would display my browsing history and I would be able to search it, sort it by Most Visited, Last Visited, etc. Since 3.6.3 I have been having issues: Firefox does not display any entries when filtering by Most Visited or Last Visited. Searching does not work regardless of what keyword I use (i.e. if I type stackoverflow it won't even find it, although it's one of the most visited web sites in my history). Is anybody experiencing similar problems? Are there any known issues that might be causing the problems that I'm seeing?

• How does RAM fail?

  - by ethanlee16

  I have an issue with a Dell Inspiron 15 (1545) laptop that refuses to open any applications (save select Microsoft programs, e.g. Security Essentials, Ctrl Panel, Windows Explorer (not Internet), regedit, Event Viewer, etc.). I've run Microsoft Memory Diagnostics Tool and it found a 'hardware problem was detected.' Does this indicate that the RAM has failed? I notice when I open programs like Word, Excel, Internet Explorer, etc., it always give me an error from WerFault.exe saying The instruction at xxxxxxx referenced memory at xxxxxxxxx. The memory could not be written. and sometimes something about illegal instructions. If it is a hardware problem, does this mean that replacing the RAM is my only option? Again, I would also like to know if RAM can fail (like hard drives) and if malware can cause RAM to fail also.

• Getting FC11 to run under VMware Server, converted from physical machine

  - by Kristian

  I have a FC11 installation that I have converted to a VMware disk image to run om my VMware Server. I converted it with qemu-img, as the VMware Converter software apparently only converts Linux hosts to VMware Infrastructure servers. The disk image boots fine (grub is loaded and boots the kernel) but it seems like the disk is not found by the kernel, and the boot process stalls. Hotplugging USB devices work (the kernel prints debug information) and I'm able to press keys (Ctrl-Alt-Delete for instance). The VMware guest OS is set to RedHat Enterprise Linux 5 (32 bit), and I have tried both the LSI Logic, LSI Logic SAS and VMware Accelerated SCSI SCSI controllers, to no avail. I'm able to boot an installer disk and get into rescue mode and mount the filesystem, so my question is, what do I need to do to the guest kernel / initrd image to make it recognize the virtual disk?

• GNU Screen: «unknown command 'vert_split'» though C-a | works

  - by etuardu

  Hi, in GNU-screen (4.00.03jw4 FAU 2-May-06) I'm able to perform a vertical split pressing C-a | (i.e. Ctrl+a, then pipe). Since I'd like to have the screen vertically splitted at the program startup, I put "vert_split" in my .screenrc file, but when I start it I can read «unknown command 'vert_split'» for few seconds in the status bar, and the screen is indeed not splitted. I can't find a solution for this in the manual. Can someone please help me? Thank you.

• What is the easiest way to get a yyyy-mm-dd hh:mm:ss timestamp hotkey on the Mac?

  - by Edward Tanguay

  On Windows I use the PSPad editor which has a nice ALT-D timestamp which you can edit the format of, e.g. yyyy-mm-dd hh:mm:ss. When working outside an editor, e.g. Google Docs, I have Autohotkey which I have programmed CTRL-D to insert a yyyy-mm-dd hh:mm:ss timestamp. I am now working on a Mac mostly using TextWrangler as my editor but I can't find a timestamp hotkey in its features. What is the easiest way to get a yyyy-mm-dd hh:mm:ss hotkey on Mac, either in a (free) text editor or a (free) autohotkey equivalent?

• dead man's switch for remote networking interventions

  - by ascobol

  Hi, As I'm going to change the network configuration of a remote server, I was thinking of some security mechanisms to protect me from accidentally loosing control on the server. The level-0 protection I'm using is a scheduled system reboot: # at now+x minutes > reboot > ctrl+D where x is the delay before reboot. While this works relatevly well for very simple tasks like playing with iptables this method has at least two drawbacks: It's not very reactive, ie a connectivity problem should be detected automatically if for example an automatic remote ssh command fails does not work anymore for x seconds. It can obviously not work if one need to modify some configuration files and then reboot to test the changes. Are you guys using some tool for the second point ? I would love to have something able to revert the system configuration in a previously known stable state if I can't join the server X minutes after reboot. Thanks!

• Starting and stopping X11 and LXDE from command line

  - by Radian

  I have a Raspberry Pi with Debian Wheezy (Raspbian) and so far I've managed to learn quite a lot about Linux just playing around, but I have a few questions for all you seasoned Linux pros out there. 1) From command line, if I execute startx, X11 will launch followed by LXDE. If I had a monitor connected, I'm imagining I would see a transition from command line to the desktop environment. Can I launch X11 first with x, then start LXDE on top of X11 afterwards with /etc/init.d/lxdm start (is this correct?) and get to the same result as startx? 2) Instead, let's say I executed /etc/init.d/lxdm start alone, would X11 start automatically (since LXDE relies on X11)? 3) From desktop, if I CTRL+ALT+F1 to get back to command line, then I should be able to shutdown LXDE using /etc/init.d/lxdm stop. Does X11 automatically close with the termination of LXDE? 4) What is the proper/safe way to shutdown X11? Thanks

• What is the difference between "su --command" and "su --session-command"?

  - by oliver

  Running # su - oliver --command bash gives a shell but also prints the warning bash: no job control in this shell, and indeed Ctrl+Z and fg/bg don't work in that shell. Running # su - oliver --session-command bash gives a shell without printing the warning, and job control indeed works. The suggestion to use --session-command comes from Starting a shell from scripts using su results in "no job control in this shell" which states "[a security fix for su] changed the behavior of the -c option and disables job control inside the called shell". But I still don't quite understand this. When should one use --command and when should one use --session-command? Is --command (aka -c) more secure? Or should one always use --session-command, and --command is just left in for backwards compatibility? FWIW, I'm using RHEL 6.4.

• Firefox: box mode?

  - by Peter Mortensen

  What is the "box mode" (for a lack of a better word) in Firefox? How can I exit it again? If I hold down the Ctrl key and left click while the cursor is over some element on a page it becomes boxed: Firefox seems to go into some special mode. What is this mode for? How can I go back to normal mode? Installed add-ons in Firefox: BetterPrivacy 1.29, NoScript 1.9.0.6 and SQLite Manager 0.4.7. (Microsoft .NET Framework Assistent 1.0 is disabled.) Platform: Firefox 3.0.6, Windows XP 64 bit SP2, 8 GB RAM.

• Why did cherokee-admin-launcher crash?

  - by DarenW

  I'm trying out the Cherokee http server on a seemingly fine machine. Following simple set-up instructions, I tried running cherokee-admin-launcher but it printed error messages and hung up. Ctrl-C did not kill it; I had to kill -9 it from another xterm. OTOH, cherokee-admin ran fine (or at least got a lot further). What is the problem with python and cherokee-admin-launcher, and how to fix it? [root@iron rc.d]# cherokee-admin-launcher Checking TCP port 9090 availability..

• Computer bluescreen-ing with 0x7A and 0xF4 errors

  - by lcarpenter

  Hiya, This computer is locking up for around 5-30 seconds before throwing Blue Screen of Death's with 0x7A and occasionally 0xF4 errors. The log files don't really show anything informative, and Windows Update doesn't show any new drivers for the HDD. Upon restart, it shows a "A disk error has occurred /n Press Ctrl+Alt+Del to continue", and to fix this I go into WinRE via the pendrive and run "bootsect /nt60 C: /force /mbr" and that seems to fix it so it boots. And then the cycle repeats. If you want any more information please ask. Thanks, Luke Carpenter

• Mark as read on delete in Outlook?

  - by x3ja

  I'd like Outlook to mark any messages I delete to be marked as read. For bonus points, I'd like it to only do this on messages that I have opened/previewed before pressing delete since this means I've looked at the content and chosen to delete it. I know I can set it to mark as read after x seconds when I'm looking at it, that's not what I want. I also know that I can move off the message & back on to it or right click to mark as read - still not what I want. I'm using Outlook 2007 in case that matters. [Edit: I just found I can at least mark as read with a keyboard shortcut: Ctrl-Q, but again, it'd be nice to not have to do this. More shortcuts here.]

• CentOS: revert python version back to original

  - by NP

  Hi all, I installed python 2.6 using the instructions here on CentOS 5.4. However I realized it was a bad move and I need to revert back to 2.4, which was there originally. Can anyone guide me on how to undo what I did here? In particular, I am not sure how to undo this: Configure ld to find your shared libs: $ cat /etc/ld.so.conf.d/opt-python2.5.conf /opt/python2.5/lib (hit enter) (hit ctrl-d to return to shell) $ ldconfig I tried removing the alias and the symlink and even re-aliasing python to /usr/bin/python, but when I try to install an RPM i get this error: error: Failed dependencies: libpython2.4.so.1.0 is needed by ... Thanks in advance.

• Have VIM jump to a ctag in an existing tab

  - by Adrian Petrescu

  I have ctags configured with my vim installation. My habit is to usually have all of the relevant files I'm working on open in tabs in vim all at once. The "problem" is that if I use Ctrl+] to jump to a ctag in a file I'm editing, it will replace the buffer in that tab, even though I have another tab already open containing that symbol. It would be much better if it just switched to that tab and jumped to the symbol there instead. This way I would always have a 1-to-1 tab-to-file ratio. I noticed in the Changenotes for the taglist.vim plugin (which I also use) has an entry that says 1. Added support for jumping to a tag/file in a new or existing tab from the taglist window (works only with Vim7 and above). However, I couldn't find anything in the documentation for Taglist (or Ctags) about how to actually do this. Can any vim gurus fill me in? Thanks!

• Fonts in Google Chrome messed up

  - by user1850463

  I recently installed new fonts on my computer that my friend sent me so I can use them in Adobe Photoshop. When I downloaded the ".zip" folder containing the fonts I unzipped the folder, pressed Ctrl+A to highlight all of the font files and then I right clicked and clicked "Install". That is how I installed the fonts. Now the fonts in Google Chrome are messed up. When I go on websites such as Stackoverflow, Facebook, etc. the fonts are different and look really odd. Random parts of text are bolded or italized, etc. I'm using the latest version of Google Chrome and Windows 8 Pro. I took 3 screenshots to show you what I mean.
