Red Hat / Fedora :: Multiple Logins At The Boot Screen?

Feb 18, 2010

Is there any method to allow multiple users to login to the main server - something like is allowed in windows ?

I am aware of how to telnet/ssh into the machine, but there are some engineering programs which need to be run on the head node (for some display issue problems on the ssh windows), which locks up the head node for another user who might need to log into the machine for their own work.

where I can set it up to permit multiple users to work at the head node without logging off, and instead allow "switch user" or something of the kind ?

Fedora :: Multiple SSH Logins With Only One Password?

Dec 30, 2009

I want to login into my main machine from my laptop,sing ssh with several linux consoles, all running mc.Is there any way to only login once with one password, and get several consoles running at the same time?It's a pain to have to ssh and give the same password for each console I want running on the main machine.I've looked at the screen package, but can't seem to get that working.What I'd really like is 3 different terminal sessions, all connected with one password. Each terminal with 3 tabs, all running mc under the same password. So that's 9 different instances of mc running remotely

Ubuntu :: Not Allow Multiple Logins To The Shell?

May 20, 2010

Is there a way to prevent a user from being able to login more than once. Not a one-time login, but a single login. What I'm trying to do here is in moving our email system, an email user would login to this account, enter some password information, sync up their email, and have the passwords files removed, then log off. Next user can log in to the same account.

The reason for the single login is to protect the user's passwords.

Fedora :: 15: Setup Gdm (multiple Screen)

Jul 24, 2011

I am just trying out Fedora for the first time (coming from Gentoo and later Ubuntu).

So far everything works fine, but I have one problem with the gnome display manager (gdm), which is responsible for the initial graphical login screen.

My graphics adapter (nvidia) has two dvi-outputs, and i use them both. One is my primary display, the other one is used for my projector (watching films etc).

When starting Fedora, unluckily, the gdm login screen is shown on the wrong output (the projector, which is only occasionally turned on). I'd like it to be shown on the primary display.

Now I learned that gdmsetup disappeared in this release of Fedora. How can I achieve this goal now? What I found out through research is that there is a config-file (/etc/gdm/custom.conf), which can be used to configure gdm. But I don't have a clue how to. I found the following official documentation: [URL].

General :: The KDE Login Screen Now Says "root Logins Are Not Allowed."?

Feb 20, 2010

Something has caused me to be locked out of root; the KDE login screen now says "root logins are not allowed." It's not as though I don't know the password--I set it up. I might have deleted something I'm not supposed to, because before this, root had also become invisible at the KDE login screen.

General :: Authentication Failure For Root Logins (Fedora 12)?

Jan 20, 2010

I just got Fedora 12, and I used su root to change the bin ownership to my primary developer account. For some reason, though, all subsequent attempts to log in as root have had authentication failure, be it through su or through the startup login screen. This does NOT occur for adminstrator tools such as Groups and Users.

Networking :: Multiple IPs One NIC Configuration Doesn't Load At Boot On Fedora 12?

Dec 2, 2009

I have a Fedora 12 system that I am trying to configure with 3 IP addresses on one NIC card. I created scripts for each of the connections I want in /etc/sysconfig/network-scripts/ and they are called ifcfg-eth0, ifcfg-eth0:1, ifcfg-eth0:2. If I run /sbin/services network restart it configures everything as I would like. When I restart the computer the only device configured is eth0 and it is set to DHCP. If I run the script again everything works. What am I missing to make this change persistent?

Fedora :: Changes In Boot Up Screen

Jan 18, 2010

After the last upgrades I've noticed that when booting up Fedora 12 the blue screen with the ball that fills up and then turns into the Fedora logo has magically changed into the old boot up of the growing line at the bottom of the page the fianlly says Fedora 12 in the lower right hand corner. What's with that? What would make it change? Also when shutting down it says in times roman font "Shutting Down." What caused the change?

Ubuntu Installation :: Vista Multiple Boot - No Boot Filename Received - No Bootable Device

Jan 2, 2010

i had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:

No boot filename received
PXE-M0F: Exiting Intel Boot Agent.

No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........

Ubuntu :: White Screen On Boot From HD - Garbled Screen On Boot From CD 9.04

Apr 21, 2010

I installed Ubuntu with a partition that was too small for any practical use, so I installed it again, thinking it would simply overwrite the other one as Windows would do. Obviously not. Now I have two Ubunto installations, neither of which work. I get a White Screen after the Ubuntu thing that shows its progress. If I try to boot from the CD, the Ubuntu thing works again, then I get a completely garbled screen which is totally unreadable and unuseable. I should also mention that I originally installed with a 19" square flatscreen from HP, but have upgraded to an Acer H233H. Since I have no clue what to do whatsover Ubuntu is just taking up space. I'd like to be able to use it, and I'd like to be able to get rid of one or other of the installations.

Ubuntu :: Multiple Boot Options In Grub Boot Menu?

Apr 3, 2010

I'm a noob but enjoying dual booting. However, every time I run update manager I get a new vmlinuz entry and now I have multiple boot options in my grub boot menu. Now when I have like 5 ubuntu entries to move past to select Windows. and the latest Ubuntu is always at the bottom so I have to annoyingly scroll down to select the latest there. I don't really understand what the vmlinuzXXX entries in the boot folder are for so I don't want to delete them. I've thought about editing the loop in the 10_linux file in the grub.d folder but it looks like its calling a function or macro or something:

linux='version_find_latest $list'

But like I said, I'm a noob to all this (a .Net developer on Windows professionally) and don't understand where this is. It looks like this function call has the logic I need to fix. Because its not finding the latest, its just finding all. How to I get back to one Ubunutu boot option like when I first installed?

Fedora :: Black Screen Upon Boot Up?

Oct 28, 2009

I downloaded a bunch of updates with PackageKit, afterwards I had to restart. Now when I did, all I would get is a blank screen, no blinking prompt line or anything. I did a cold boot and the same thing happened. So, I tried it a third time and all is fine. I'm running FC11 and I'm glad everything is back to normal,but what might have caused this in the first place?

Fedora :: Does The Boot Screen Work In F12

Nov 18, 2009

Just download F12 and was thinking of installing. But, I was hoping someone could tell me if the start up screen actually works now? I recall it just being a blue bar at the bottom.

Is Plymouth ( I think that is what it is called) working yet? Or do I still have to modify files in order to get it to work?

I realize the above is no reason NOT to install F12, but I am curious anywho I still need more Linux XP points.

Fedora :: Stuck At Boot Screen

Aug 19, 2010

fedora 13.I have ran fedora for a little while now and its quite good, a lot more stable than I was led to believe and add/remove tool has a great variety. So today I was booting up and decided to "type" as fedora was booting. The long and the short of this is that fedora stops at this well the bar fills just before nvidia screen/login dialog pops up and freezes there.

Ubuntu :: Multiple Boot Attempts Before Successful Boot

Oct 22, 2010

I'm using Ubuntu Maverick which seems to run ok. The problem is when booting my PC. Often it takes anywhere between two and six attempts to boot before a successful boot. Sometimes it fails with "No signal" before it reaches the grub screen, sometimes is passes grub only to fail 15 secs later with a "No signal".I have an NVidia Ge Force 6600 LE graphics card, with the latest driver 260.19.06.

Fedora Installation :: White Screen On Boot Of F 10

Jan 7, 2009

I have a Gigabyte GA-MA790FX-DS5 with an AMD Athlon 64 X2 and 4GB RAM. The MoBo does not have embedded video. My main video card is a Diamond Radeon HD3650 PCIe. I was unable to initially install F 10 as the screen would blank out (Black Screen) after it would start Anaconda. I attempted to boot using the suggested option of nomodeset with no change of symptoms. I then switched out to an older PCI video card (NVIDIA GeForce FX5200) and was able to go through the install. Now I am attempting to switch back to my preferred card (HD3650) and just before the GDM screen appears the screen goes to solid white and no ability to switch to another VT. I have been unsuccessful at finding any workarounds for this. I thought the issues were with the older proprietary chipsets pre open source of ATI which was supposedly older than the R500 series, but I guess I'm wrong.

Fedora :: Lock At Boot Up Before Get Into The Login Screen

Nov 20, 2009

I just installed Fedora 12 earlier today using preupgrade. Everything seems to work alright, but I do have a couple of problems. I've had this happen twice already, but when I'm booting up, my machine will freeze once the Fedora logo is shown right before I get into the login screen. Another problem I've had is when I do boot into KDE I'll see an ! icon next to the clock telling me that there has been a crash in the kernel.

Edit: Update- It only hangs when I reboot. If I restart in windows and try to boot fedora, it hangs, if I restart in Fedora, it will hang after the restart. The only way I can boot Fedora is from a cold boot

Edit: I seemed to have fixed the problem after searching Google for 20 minutes. I just ran this command as root.. #chcon -t system_dbusd_exec_t /bin/dbus-daemon

I have a big LCD screen.I make it 90 degrees retated to play games .But I want to know :if I can get rotation in boot up? I'm using Fedora 12 in KDE. My screen display driver is Intel . I think can write something into /etc/X11/xorg.conf to make it,or write into KDE's init script /usr/bin/startkde ( if there is a command like"rotate 90",then I can write it here).

Fedora :: F14 Boot Screen - Show Progress?

Dec 26, 2010

I just installed the latest updates for Fedora 14, and a restart was necessary so I did. Then, it didn't reboot! It hung when the cursive Fedora "f" was there for about 15 minutes. I had guessed that maybe it was doing an automatic fsck disk check, but I'm not sure.

Anyway, I couldn't change to tty2 etc while this was happening and for all I knew, the system was frozen. Is there a way to see the load progress (the text) while booting?

FYI, after 1 extremely slow but eventually successful boot, everything is back to normal with rapid boot times.
