Ubuntu :: Sudo Or User Login Not Working - Fresh Install?
Aug 17, 2011
I have this weird problem after a fresh install of Ubuntu 11.04: I can enter desktop using autologin but if i open a terminal i cant run anything as superuser ried:
sudo -i
sudo su
sudo <command>
gksudo <command>
i get somthing like: error, invalid password etc etc 3 incorrect login attemtps Also if i ALT+F2 or close gnome session i cannot login back with my username, same error notes: 1. the password is right, i did a second install of ubuntu to make sure it was not my mistake 2. groups seems ok, user is in admin groups 3. I have a similar error, same computer but on an old installation that i ve updated since ubuntu 9.04 to 10.04, then 11.04 but. But here if i try the password a couple of times then i get it working.
I have just installed Kubuntu 10.04, but can't login into it. I enter correct user/pass, then it tries to go into KDE, but suddenly drop back to login window.The same situation with failsafeX.A olso tried different users and several times reinstalled Kubuntu. Here is my "~/.xsession-errors"

I decide to install F15 (other machines run F14) and after a pretty smooth install and reboot, I try to login and get the message "Oh no, something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again". But no matter how long I try, I keep getting this message. Then I go to crt-alt-F2, and try to "yum install gnome-panel". Then it shows that I don't have any network connection at all, even though I did install my network. I'm thinking of installing F14 now.
I installed openSUSE 11.4 today and I have a problem. After login, KDE Plasma hangs for about 30sec and I can't do anything. The keyboard and the mouse are working, but if I click, I don't get any response only after about 30sec.
This is a fresh install, 32bit, I'm using only the Oss, Non-Oss and update repositories and the system is up to date.
I have an nvidia 9500M GS graphics card, first I thought it is a driver bug, but I tried both the stable 260.19.44 and the latest 270.41.03 drivers, and was no difference.
I made an another user to try with a clean kde, but the same happened.
I have nothing in my Autostart directory, and I cleaned also the /etc/xdg/autostart dir, leaving there only the pulseaudio related files.
I have tried to install openSuse several times and the same problem would persistRight after installation, when the prompt to log in shows up, I enter a username and a password, but it says that login failed. I am sure I type in the correct data as I have written down the username and the password I register during the installation.Also, after the installation finishes, the computer restarts automatically, though instead of restarting it goes into a mode similar to stand by. The screen is blank and the media buttons of the keyboard are lit, but nothing happens, so I just restart manually. Could this have something to do with it
I've now tried several times to install a fresh copy Fedora 13 i386 on my old Dell laptop, but each time I reboot the laptop I get the first-time welcome screen which asks you to create a user. When I re-enter my user info, it tells me that there's already a folder created for that user. After rebooting, I'm back to that screen. Does anyone know what's going on here?
I've installed a fresh Debian amd64 DVD version on my small HP Compaq 6537s / AMD Athlon X2 / 64. Everything went fine, I rebooted, the graphical login screen appeared, so I thought I will be able at last to run Debian on a computer ...
But then after login, the login Window disappeared, the "Debian" logo too, and... that's all folks! A nice blank screen. But the mouse is still perfectly drawn, so it's kind of weird.
Here's what tells me "uname -a" :
Linux olivierdebian 2.6.26-2-amd64 #1 SMP Sun Nov 21 09:17:22 UTC 2010 x86_64 GNU/Linux
If I go to CTRL-ALT-F1, i login as root and I do a "/etc/init.d/gdm restart", I have the login screen back and this is once again the same scenario: login => ok => blank screen with mouse properly drawn and the Debian background color still there.
I have downloaded the latest testing image today (debian-testing-amd64-kde-CD-1.iso), install went just fine.
On boot, I get as far as the KDE login screen, where my user and password are seemingly accepted. Seemingly, as after this point, the screen is a complete mess. This 'mess' differs between attempts: it could be full of black and white squares, themselves made up of noise pixels; once it was like a normal screen after it had been through a blender, i.e. bits of the DE but awfully mixed up. (My judgement would be that the video pointers is set to point at the wrong part of memory... or is that my old-school point of view getting in the way? Whichever, it provides you with an idea of what it looks like.)
Running on an Nvidia GTS250 card, with two monitors (2 x DVI).
I have not installed any NV propriety drivers, as this is the first boot(s).
There is no xorg.conf present on the system; and I cannot find anything obvious in xorg.log (but then, I wouldn't know what to look for).
I use grub legacy, from my existing PCLOS partition (though this should not be an issue as I get as far as the KDE login screen, pretty as please).
Regarding the install itself, I took the above mentioned testing image as a way to get Squeeze. I assume this was the right way to do this at current time.
I initially installed Debian 8 onto my iMac G5 (with KDE), and it would boot to a black screen. I then tried again, and reformatted+reinstalled with only "Standard system utilities", "Print server", and "SSH server".The boot hangs before I get to a log-in prompt. Please see the attached log files I pulled off by booting from the rescue CD option. (I got an error when attaching the log files, so I used tinyupload to upload the files.URL....

I just installed Fedora 13 on a new computer and the timed login for gnome does not work unless you manually select it. This surprised me as I upgraded a separate computer to Fedora 13 and the timed login feature still correctly functions and does not require user interaction.
Adding the above to /etc/gdm/custom.conf only adds an Automatic Login option that you have to manually select and then the computer will login. I would deem this less than useful.
I know you can substitute the timed login with the automatic login and it will instantly login, but this provides no option to select another user. I have been unable to find any information why this feature no longer works and wanted to know if there is a new way or if anyone knows why the timed login feature was crippled.
I just built my PC and loaded ubuntu on it. When the ubuntu desktop comes up everything looks ok. but when I click on any of the drop down menus, or anything else for that matter, the computer freezes immediately. I,ve tried copying the iso boot file to a new cd and reloading ubuntu but the problem remains. I've also tried removing one of the two ram sticks but again, the problem remains.

I just installed ubuntu 10 on my pc and unfortunatly I don't have internet. I only have one pc wired to my 2wire modem. I want to use dhcp, no static ip if possible.
I have a computer with redhat installed that once it boots up it comes to an application login screen. I want to bypass that and get root access to reformat hard drive and install latest version of Debian Linux.
I installed Ubuntu 10.04 from a Live CD today. Everything seemed to go fine, I chose to wipe the entire disk. However, it would only startup once. Now, when I turn on my laptop, all I get is a blank screen.
I had a look at my partitions with GParted on the Live CD and noticed that there was a 1 MiB unallocated space just before it. code...
I just installed lubuntu 10.04 on an old machine and cant get the sound to work. I have been through the sticky but cant seem to see the problem. Heres the useful output:
I just got done with a fresh install of 11.04. So far I like the new update and face lift. The only thing I do not like is that I can not use my laptops WiFi I have a Compaq Presario V5101US. Below info is from doing lspci command in the terminal...
Would it be safe to say that if I build a restricted user: "Desktop" or "unprivileged" user I will be ok? From what I understand - most scripts or applications cannot install without the 'sudo' prompt and user input.
After a fresh install of Ubuntu 11.04 (from 10.04) and spending several hours trying to figure out why the ad-hoc connection between my two computers (Fedora14 <-> Ubuntu 11.04) no longer worked - it had worked fine for almost 2 years with 10.04 - I've finally concluded it was a DHCP problem. This realisation (which was slow in coming!) dawned on me when I reversed my setup and configured the Fedora box as the DHCP server and everything was suddenly working perfectly! A quick internet search threw up an installation file called "isc-dhcp-server" which other Ubuntu 11.04 - related forums are also complaining about. My problem is that this file, although available in the repository, is not even installed!!!
It seems unlikely that the developers forgot to include DHCP support, so I hope someone can point me in the right direction.

Talk about being thrown in at the deep end! I am not used to linux systems but I have inherited a linux based internet setup that I need to take care of.Two machines (both have centOS 5) are networked and one is accessing the /home directory so people can log onto their personal home folder.The log in screen on the second machine usually just requires the individual to input their username and password and it automatically accesses their folder on the other machine.At the moment it doesnt and comes back with an error saying that the session lasted less than 10 seconds. Looking at the error message it is saying that the profile was not found and couldnt create per-user gnome configuration directory.
I am able to log in to the local root user on the machine and I can see the networked drive and even access the home directory.looking thru the network setting I see that the other machine seems to be acting as a samba server?? and is connected with SFTP?Any idea how to fix this problem as I have a load of guys sharing 1 PC for internet access in the middle of the atlantic Ocean on a ship!
Just tried new Fedora 11 yesterday, did a fresh install with ext3 /boot and ext4 file system, booting looks great, but wireless doesn't work. I have tried using broadcom-wl, dnmouse script, dnmouse broadcom f11 rpm, fwcutter but not ndiswrapper
Code: # lspci -vvv | grep 4312 02:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Hewlett-Packard Company BCM4312 802.11b/g Wireless LAN Controller ifconfig only shows eth0, lo and pan0 interfaces, and got nothing from iwconfig...
Code: # iwconfig lo no wireless extensions. eth0 no wireless extensions. pan0 no wireless extensions.
Even tried to blacklist b43 after installing broadcom-wl driver, but no luck. Broadcom-wl works fine with Fedora 10 on my laptop, is it possibly because of the new ext4 file system? Should I try ndiswrapper or install Fedora 10 again and do a preupgrade? I also use fedora at work.
I did a fresh install of Ubuntu 10.10, coming from 10.04 and the wired network connection sometimes works, and sometimes doesn't. Right now I manually removed current network from System-->Preferences--> network connections, define a new one, and reboot. This usually fixes, although I've had to do this two times in the past.
Other general info Ubuntu 10.10 64bit, EVGA P55 motherboard, on board either net.
Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code: su [insert username of old account without brackets] sudo usermod -G admin [username of new admin account without brackets] exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code: su [insert username of old account without brackets] Means were going to Switch User to the old admin account Code: sudo usermod -G admin [username of new admin account without brackets] This simply adds the admin group to the secondary group list for the new user Code: exit Pretty self explanatory
