Fedora Hardware :: Remove Via The Command Line Prior To Actually Starting?
Feb 17, 2010
Yesterday i finally got around to installing my graphics card (NVIDIA GeForce 8400M CS) on fedora 12 by using the command yum install kmod-nvidia the terminal then told me that it installed correctly so i rebooted my system. Now when i boot up into fedora, it loads and when the sign in window is about to appear instead my screen shows random colors all over the place. I am hoping someone can tell me how to remove this via the command line prior to actually starting fedora.
I've just added an application to load on startup in gnome.At first gnome loads properly,but after few seconds that application starts automatically and I can see its icon on taskbar , then gnome freezes and I can't do anything in gui.
How I can remove that application from starup of gnome using command line?
I am a redhat admin and also use Ubuntu. Installed opensuse on my home machine to give it a whirl. I can't seem to figure out why i can't open gui application from the command line.
I receive a GTK error when trying to open with sudo. What am i doing wrong?
EDIT: NM solved my own question, had to add DISPLAY and XAUTHORITY to the sudoers file.
At the Command Line Prompt I am able to start some Applications (such as openoffice.org or evolution) and the command line prompt re-appears after program is launched and I can continue working in that Terminal. However, other Applications, such as Totem or Blackboard will launch from the Terminal but the Prompt does not re-appear. Where Totem is concerned I get a message stating "sha module is deprecated use hashlib module instead". Where Blackboard is concerned the command line does not reappear. I have to use Ctrl + C to get the command line back but this closes the application as well! Or, I have to open a new Terminal. why some applications will start from the command line and others do not? How do you get the prompt back (other than q or Ctrl + c) thanks to all and kindest regards ( I am using Ubuntu 9.04)
I'm studying Information Technology and doing Linux as part of it. One of the questions in my text book is: Describe three different ways to start a command line interpreter when using the Gnome desktop of openSUSE Linux. I can't for the life of me make sense out of it.
I would like to insert prior to the word "three" all items from this second file with the following contents:
Code:
four three two one
Now my issue is, and I have been using both sed and awk currently, that after the second line of the new file is read there will of course now be 2 copies of the word "three" but I would like to only insert the final 2 words, ie "two" and "one" prior to only the first occurrence of the word "three" so final file will look like:
Code:
one two four
[code]....
So here there is now only one of each word from the second file joined to make the new file. For simple code I have tried something like the following:
Code:
while read line do awk -v n=$line '!f && /three/{print n;f++}1' file1 > tmp_file mv tmp_file file1 done < file2
Now this works but seems very clumsy to me. There is obviously a better sed and / or awk out there.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
Where exactly are the temporary files stored, in /tmp or /var/tmp. How can i remove temporary files through command line? What is the difference between these two directories?
Is there any way to quickly remove multiple related packages from the command line instead of having to enter the name of every single one? I am trying to remove OpenOffice from my server running 10.04. It would work nicely if I could get a list of packages without line breaks, such as the list displayed by aptitude when upgrading. That way I could just paste the package list into the terminal. However, "aptitude search 'openoffice'" dumps a long list on many lines that cannot be used that way.
Is there a command line alternative to clicking on "Safely Remove Drive" in nautilus?
When I click on "Safely Remove Drive" in nautilus, the USB HDD attached (WD Elements) vanishes from the nautilus "places" list, the drive spins down, and the light on the drive dims to indicate that it is powered down.
I have tried the "umount" command as well as the "eject" command from the terminal, but they both only seem to unmount the drive, as it is still shown in the nautilus "places" list and the light on the drive stays bright.
I was wondering... if I can "/etc/rc.d/init.d/NetworkManager stop" then, /sbin/service network restart, ifup wlan0. with out using /etc/rc.d/init.d/NetworkManager which other command I can use to get the AP around my place?
My site was recently hacked and a line of <JAVASCRIPT> was inserted into all my php files. Is there a way to pull just that one line out of all the php files on the server? I was thinking of using a grep -iR <CODE> *.php then piping thru sed
I may need to handle a Red Hat server soon and thought that has the same command line.Where do I start if I wanted to learn the command line? Especially, how do you connect to a Redhat / Fedora Server using console on windows and do C programming
i recently did some changes to my hard disk partitonand now linux is in hd0,6when i booted my pc,i got the grub commmand line interfaceso,I think that i need to edit grub.conf in fedora 14then at cmd i did this:
grub> root (hd0,6) grub> kernel (hd0,6)/vmlinuz file not found
I decided on a whim to pursue certifications in other operating systems (currently 70-620 and 70-290 certified with Microsoft) and bought a book on Fedora 10 and installed it on my extra PC. First issue I ran into was that due to my graphics card being an ATI I needed to run in text mode (based off posts on these forums) then once I finally got everything under control and installed, it loads directly into Command Prompt (you folks call it GRUB right?) I can log in as root but I can't do anything this way.It won't even allow me to do things like accept the end user license agreement or create new users or see the GUI.
When I do System > Applications > Update System, it brings up a list of updates, and can tell me what each update is meant to fix (i.e. "fixes a bug in the flux capacitor so time travel works again (CVE-01234)"). How do I get similar info from the command line- I can't get it through yum, can I?
I'm experiencing a peculiar problem with Fedora 12. There is a ten-second delay when various command-line applications (e.g. ssh, wget) connect to remote machines for the first time. The delay is also seen when the remote machine name does not exist.Subsequent connections to the same remote machine are immediate.This isn't a DNS delay - the host and dig commands return immediately, for both existing and non-existant hostnames. It's not a reverse DNS lookup by the remote machine either: other Fedora 10 machines do not experience this delay and neither did my two Fedora 12 machines when they were running Fedora 10.
time this was something to do with nscd, the name service caching daemon. Stopping nscd changes the delay to five seconds, but subsequent connections are no longer immediate - there is again a 5 second delay. This implies that nscd is caching the names correctly.The delays are always precisely 10 seconds, or 5 seconds when nscd is not running. I have confirmed this with the time command. There appears to be no odd network traffic (tested with tcpdump) and nscd appears to be running normally. I've confirmed this with a Fedora 12 live CD as well - nscd is not started at boot, but once started, the machine behaves in exactly the way described above.
with that said i burned fedora 8, 10, and 11 checked the sha1 verified everything was fine i had originally installed fedora 8 on an old pc i had from windows XP without any problems messed with it some, upgraded to 10 again no problems. tired to update 11 got a message about ext3 not found ext4 not found, re installed 10 the loader loads up now i have a blank screen with a cursor it the left hand corner
again i had 10 installed fine prior to all this can any one point me in the right direction to solve this issue or am i way over my head trying to figure this stuff out. i have spent 3 days searching these forums.
i'm just not quite sure what i need to do. oh, i tried to install 8 again and it wouldn't take either. i think the 10 problem has something to do with the graphic driver it's a geforce 7400 nvidia and something to do with the grub, but like i said i get a blinking cursor and not quite sure how to access the grub or command line.
I've been working in a program in BASH and would like to measure its efficiency in different machines. Of course I am able to display the date at the beginning and at the end of its execution, but I'd rather use some sort of timer function to measure in seconds its speed. Is there any timer function available through command line?
I use F13. How can I control the volume of my desktop ssh'ing into it from my laptop?
I use the laptop like a remote control to control my desktop through vnc while watching movies, but changing volume through this setup is a bit too cumbersome and clumsy. I tried alsamixer but it behaves strangely and doesn't change volume.
While trying to download themes for fedora 12,I get to the end it ask for my PW (in sudo) then says it is incorrect.When in graphic inter phase all my passwords are excepted.I've been reading the linux manuel. but can't find the anwser.If I am to put anouther password in where do I do that and how.
I have a list of domains in "domains.txt" , and I wanted to put an "nslookup" in front of each line and run it.. However I could not figure out a command for it.. Any ideas how to do this simple task?
I have a couple of backup scri ts. I use a rather cumbersome method to backup evolution. I finally realized I can backup evolution easily from its File Menu. Can I do this directly from the command line, so that I can use it in a script?
My USB ports are not easily accessible from where I use my PC, Sometimes, I eject or unmount some USB device, only to realize that I forgot to copy or delete some file. I don't want to get up, go to the CPU, unplug and replug the USB device, go back to my sit. I don't want to execute some boring mounting command as root just to mount this particular device. What I want is a fast command that just rescan my USB ports and mount everything where it should be, as if I have make the effort of standing up and unplugin and repluggin the USB device. Does this command exists
