I'm running a Toshiba Satellite laptop and am having trouble with the function or Fn keys. When running xev from the terminal I get no output for when I press the Fn key and I can't assign any keyboard shortcuts using it.

Ubuntu / Apple :: 10.10 - Function Keys To Work Without Pressing "fn"?

Oct 15, 2010

I have a late 2009 MacBook, white, unibody, and I wish for the F1-F12 function keys to have their primary role as F1-F12 keys, but allow me to use them as media/volume/brightness keys as a secondary role, when the "fn" key is held down at the same time as corresponding key.

Fedora X86/64bit :: Running F11 I586 On Laptop / System Shut Off (not A Normal OS Shut Down, But A Sudden Power Off Without Warning)?

Oct 13, 2009

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

Ubuntu :: 10 Machine Won't Shut Down?

Jun 30, 2010

When I shut my Ubuntu 10.04 (Dell B110) down, it immediately turns back on and boots up.The same thing happens when I shut the machine down via the terminal (sudo shutdown -h now)The machine also boots up into XP and Win 7. When I shut down the machine from those two OS's, it works fine.I have found a thread or two here in which users seem to be reporting a similar problem --- but they all seem to be able to shut down via the command line

General :: Get Machine To Shut Down?

Dec 22, 2010

I disabled autologin as one suggestion on how to get the machine to shut down.

But now, I cannot get to the system, except at a command prompt, and gdm will not give the display. I can login, but cannot do anything else, including getting to a desktop or to the administration section to recheck the autologin option.

How do I do this?

Ubuntu :: Machine Shut Down When Running Idle?

Sep 3, 2010

I recently got my laptop setup as an Ubuntu machine, but if I just leave it running, after a while I'll look over and see that it has shut down.

Ubuntu Servers :: Cannot Shut Down Remote Machine / Server?

Mar 21, 2010

I am running a local webserver mainly for development. I have everything set up. The issue I currently have is that I cannot shut down the machine from the command line. I can issue the command but the machine remains on. I also cannot get to the desktop via VNC.The reason for this, is that there is no monitor attached so Ubuntu says that it is trying to run in Low Graphics Mode. I found this out as I plugged the monitor in to my server.So question is, how do I get around this? How can I set up Ubuntu to get past this, or do I need to install Ubuntu Server?

I run a number of distros. I often ssh into the machine. However depending on which distro I am using, the RSA key is different.So what I will do is delete ~/.ssh/known_hosts on the machine I am using and ssh in. what i was wondering is whether using ssh-keygen and creating the same passphrase for the distros would remove this problem?

Ubuntu :: Safely Getting Rid Of XP On A Dual Boot/dual HD Machine?

Feb 3, 2010

I have XP on my IDE hard drive and Ubuntu on my USB hard drive (which is really an IDE drive with a USB adapter and external power souce). We've used Windows once in the past month, so we decided to jettison it. Two questions: 1. Can we simply delete all partiitions on the IDE hard drive and reformat or will this cause problems? 2 Is the write-speed gain worth switching the drives out, putting the Ubuntu drive in my IDE slot and my freshly wiped drive on the USB adapter?

Fedora :: Clean / Tmp Safely At Shutdown

Jan 20, 2010

I have been using this tip at URL.. to delete the temporary files created in /tmp for quite a few Fedora versions. But, I just found out that it does not work in F12. Is there are reason why it doesn't work?

You can put this into /etc/rc.d/init.d/syslog into the "stop)" section. This will clean up /tmp at every shutdown and keep your disk clean. Please note that you should not run this command when X-Windows is running.

Fedora :: Slow Boot Sequence ?

Mar 14, 2010

Since the yesterdays updates the boot process lasts terribly long of my Fedora 12 on a x86_64 system. It lasts about 10 minutes or longer. The strangest thing is that if I press keys (any of them) it goes faster (about 1 minute). There are no errors or other things which might be the reason for such a behaver.

Fedora :: How To Find A Collating Sequence

May 13, 2010

Fedora Core 12 I must be going mad, but I thought I used to use a command such as:

grep -r ^[a-z] *|grep .....

to do a recursive search to find all files that had lines starting with lower case a to z.

If I try that under FC12 (this is a newish install), it also finds uppercase A to Z.

Is there a collating type sequence or locale that I have incorrectly set?

PS just for info, the following shows the problem:
(Linux)retsol610 :stevet : /home/stevet> echo ABC |grep ^[a-z]
(Linux)retsol610 :stevet : /home/stevet> echo abc |grep ^[A-Z]


ie the whole range matching seems a bit 'screwy'. A-z should give x01-x58 so A-z should be be valid and include a couple of spcial chars - but gives a range error. On the other hand, a-Z should pose a problem as that's a backward range - but that seems to search ok.

Does any one else get this in FC12 (I've just tried in RH EL5 and grep ^[a-z] ... works fine)? My locale is:

Fedora :: Difference Between Unmount And Safely Remove

Mar 25, 2010

I have an external HDD which I use under Fedora. After finishing with my work, I unmount all the mounted partitions of the external HDD & then proceed to switch it off. The HDD partitions are unmounted but they are still visible(but not mounted) under computer. The HDD still seems to spin. But when I click on "Safely Remove Drive" they disappear from Computer & also the HDD stops spinning albeit the switch on HDD being powered on. So what should I use "Unmount" or "Safely Remove". What is the difference between the two?

Fedora Installation :: Safely Removing Gnome

Jun 15, 2011

I've been using Gnome for several years and haven't had any real problems with it. Now, however, I find the descriptions of what Gnome 3 and the Gnome Shell quite unsettling. That is, the Gnome devs have added a number of things I don't want, removed things I do want and made it impossible to configure Gnome 3 to work anywhere near what I want without adding unsupported third-party extensions. (Note: this is neither a complaint nor a flame; it's just a statement of my personal taste and any attempts to argue about it will be ignored.)

Currently, I have installed XFCE and am very happy with it on my two F14 boxes. I know that if and when I move to F15 (or F16 if 15 continues to be as problematic as it is so far) the upgrade will include Gnome 3, even though I don't use it. I'd like, therefore, to remove it but without removing any bits and pieces of it that are needed by whatever programs I'm using. What's the safest way to do this?

Fedora :: 30 Seconds Of No Activity During Boot Sequence

Nov 22, 2009

I have been enjoying Fedora 11 for sometime, and decided to try Fedora 12. All in all it is working, but the boot sequence seemed much slower. I decided to use bootchart to examine the boot process on my old F11 and new F12 installations. The result show F11 booting in ~34 seconds, and F12 booting in ~57 seconds. Interestingly, the first 30 seconds show that only kthreadd, khelper, and ata/0 are running. CPU and disk utilization are both zero during this 30 seconds span, then all of a sudden everything starts loading, CPU and Disk utilization spike up, and ~23 seconds later I get to the login screen. I sent an email to Harald Hoyer about this, and to my surprise he was kind enough to respond. He suggested I check the BIOS to make sure I had disabled the floppy drive, which I did. The problem persists, so I was wondering if anyone here was having a similar issue and if so how they have dealt with it. I have blacklisted the floppy module (just to make sure)

Fedora :: Simple Display Of Systemd Service Sequence?

Jul 13, 2011

What's the best way to get a list of the start order of services from systemd? Yes, I've tried


systemctl --order

This looks like the output I would expect, except that if that list is the system service start order, then my system is hosed. I certainly hope that my system is not starting nfs service before all the /usr/export filesystems are mounted.

I tried


systemd --test --system

but that generates over 22 thousand lines of gibberish! I filtered that with


systemd --test --system | grep -- -> | grep Unit | grep -i service

And it's less gibberish, but it's ALMOST the reverse order of the first command, and still pretty crazy.Ultimately, I need to discover, and fix the order of the services started by systemd, because they were mangled during the upgrade from Fedora 14 I hope that "systemctl --order" is either not the real deal, or I'm reading it wrong. Because if it is, I'm afraid I have a huge problem to fix.

General :: System Not Finding Fedora 15 On Pre-Upgrade Sequence

Although I tried to upgrade from Fedora 14 to 15 using Pre-Upgrade, my system does not find Fedora 15 at the end when the Pre-up-grade sequence. On the very last step when Pre upgrade reboots my computer it just goes straight back into Fedora 14. No choices (Fedora 14 or Fedora 15 Upgrade Kernel) are shown.
