Ubuntu Installation :: Log In Twice - Locked Screen Not On Reboot Or Switch Users
Oct 16, 2010
I've been running Ubuntu Maverick as a fresh install since release, and for the last 2 days, I'm having to log in twice! This is only on a locked screen, not on reboot or switch users. After the first login, I see the desktop for a second, then the screen goes blank. I wiggle the mouse and the login screen is there again. The 2nd login goes as normal.
I have gradually been installing things as I need them over the week since install, but I can't pin it down to any of those. It's getting pretty annoying when the screen saver kicks in!

When I install Ubuntu 11.04 with Wubi, I get this freeze screen after I reboot and get past the Ubuntu splash screen: url
As you can see, it's a scrambled picture of my Windows desktop. This happens with every other version of Ubuntu also.
I'm running a 64-bit PC and I don't wanna waste another CD or use a USB to install, because I actually progress further in my efforts whenever I use Wubi.

My company has policy that user accounts expire once a month and they also get locked out if they re-try login more than 3 times (pam_tally). It gets very annoying every time they come and ask to get password changed.How do I let users change their own password? Also let the system email them every day for two weeks before password expiration and until they change their password?

I'm running Ardour, and when I launch it I get the following:
Code:

This might cause Ardour to run out of memory before your system runs

I have a 10x2tb disk array that i'm trying to build into a single software raid 5 i have tried this 2 times now the first it made it to 58.7% and the machine locked up and the array would not restart after a reboot. On my 2nd try all was looking good until about 50% i noticed that the speed dropped in 1/2 and that ksoftirqd/2 is taking up a lot of cpu (about 90%) the md0_resync and md0_raid5 are also taking 60-90% when the build started they took 7%. when i do a dmesg i see a lot of the message compute_blocknr: map not correct.
For a little info on the physical setup this is running on an Atom 510 with 2GB of mem the drives are connected to an addonics 4-Port RAID 5 / JBOD SATA II PCI Controller using the sil3124 chipset. I'm using 2 addonics 5X1 SATA Port Multiplier connected to the controller to get the 10 drives attached. All drive show up and don't seem to have any issues. I'm running a fully updated as of 3/20/10 version of centos 5.4
I will let this continue to run over night but i expect it to be locked up by morning if it follows what the last attempt did.

Login as myself, girlfriend wants to use her login to check something, all good.I switch back to myself, I get a black screen with just my cursor. Most annoying. I have to ctrl-alt-f1 to reboot. I've tried killing various process from the term, but nada. I've also tried uninstalling gnome-screensaver as was mentioned in another thread when I searched, but no joy there so far.

I started a remote VNC connection from my Windows pc to my Ubuntu desktop, got presented with the Ubuntu login screen. Entered my password and accidently clicked the "Switch user" key instead of "Unlock".
The login panel became grey and now I cant do anything (I guess its because there is no other user). When I exit and enter through VNC I allways come back at the same grey screen (see screenshot below).
Is there any way of bypassing this and unlock my ubuntu desktop?
The problem: (After clicking switch user)

I'm trying to install ubuntu alongside Windows 7 on a HP Pavilion DV3. When I reboot I'm given the option to either boot into windows or ubuntu (this is after running the wubi program from the ubuntu website); when I select ubuntu it says that the installation will continue but the screen then goes very dark like the brightness has been turned right down. In the center of the screen I can faintly see the word ubuntu. I've tried using the hot-keys on the laptop to turn the brightness up but this doesn't work. I've also tried installing from CD but his doesn't work either and I get the same problem. This is my first time installing ubuntu so I'm not familiar with how the installation process works. Also if any other details are needed I'll be happy to give them.

I just installed Ubuntu on the second partition of my hard drive. I have Windows 7 installed on the first partition. My problem is is that when I rebooted after a successful OS installation and apparent grub install, it went straight to boot up Windows 7. There's probably a simple way to get the grub menu to appear that I'm unaware of, right?

I have fedora 12 and I tried to change the screen resolution under the system menu to a higher one and it changed but now I dont have any menus and I'm not sure if I can use quick keys to go back to the display preferences to reset the screen resolution. Is there anyway I could run the display preferences by running a command in the bash shell or is there a quick key that allows menu access.

I had ubuntu running just fine on another computer, but had to move things around to make Windows7 run better. So after backing up Home, I switched hard drives, pulled the video card, and adjusted RAM, I tried booting up. The computer found all the changes and did its thing. But then it hung with a blank screen. I figured that it didn't recongnize the video driver for this computer, or something, so I did a fresh install with 9.10 to start over from scratch. The boot up went great, and finished completely. I made a few changes to the desktop, and loaded in my archived firefox bookmarks and evolution files. After rebooting, the first ubuntu logo came up, but then the blank screen, with no drum sounds. I tried a few more times rebooting and hitting esc, but I don't know what I am doing at that menu. I also tried the F1 option, but again, I don't know anything. One other time I was able to boot into ubuntu all the way when I was hitting esc slowing (waiting) and somehow was able to get the login and the desktop just fine. I haven't been able to get that to happen again.
Can someone walk me through the steps to troubleshoot this? I don't know any terminal jargon or commands, and haven't really got a clue, but I really want to learn and figure this out. I don't even know how to go in from the command line to see what my system specs or video specs are to tell you.

Using Ubuntu and any Linux OS. I installed Ubuntu using the Wubi installer. Everything went fine. When the install wizard completed and asked to Reboot Now, I did. When my computer rebooted, the Windows Boot Manager doesn't appear and it goes straight to Windows.
I'm using 32 bit Vista and have an AMD Athlon X2 Dual Core Processor 5000+. When using Wubi, the download defaults to the AMD 64 version and that is what I have installed.

I tried to update my main computer from Ubuntu 10.0 to 11.04. I wish I could remember what it said, but it crashed during the update. The lights on the keyboard were flashing on and off as well. When I try to boot, all I get is a black screen and flashing lights. The Ubuntu recover also has the same thing. I am going to try a fresh install. For some reason I am leaning to the power manager, but I am no where near sure.

I was able to get Fedora 10 to run on VirtualBox. Since the system wouldn't let me set the resolution to anything bigger than 800 x 600, I decided to get the nVidia driver (I'm running the nVidia 8400m G). I did it through this guy's tutorial: [URL]... After rebooting, I see the loading bars and everything, but I get a blank screen with a cursor. After pressing ctrl+alt+F3, I was able to log in to the root and execute the "akmod builds the required kmod on bootup" under the "For GeForce 8 series" [URL]... After a reboot, I still get the same thing. Will I have to reinstall Fedora 10 and just not update the nVidia graphics drivers? I have a 20" monitor that has a resolution of 1600 x 1050 and I would really like to take advantage of that.

The wubi installer copied files successfully and asked for reboot. After booting into Xubuntu the flashing logo appeared for a minute. And then the screen looked as if it was trying to show something but could not and flickered and then became dark this continued till half an hour and then I pressed Alt+Ctrl+Del.I tried all the modes but to no avail, only the last mode with command line was working. But it was not helpful for me becoz I dont know most of the commands.When I tried "Verbose Mode" as directed by the WubiGuide - Ubuntu Wiki, CTRL+ALT+F2 did not work when the installer stopped.The computer I use is assembled with Intel pentium 4, VIA chipset and Mercury(Kobian) motherboard.

First the computer wouldn't reboot after the update, blank screen, then i manually reboted and now some programs don't work (ubuntu software center, update maneger, avant window navigator)
i assume the update did some damage, so how can i repair this, is there a recovery tool or something.

who installed nvidia drivers on Ubuntu 10.04 and gets a terminal screen on reboot with no GUI.I came across this fix trying to install the drivers on Ubuntu 10.10. later i find that the same thing happens to me on 10.04 but one of the fixes i came across works perfect with it. Ok, so you just installed ubuntu 10.04 updated it through update manager and installed your nvidia drivers but when you rebooted and tried to log on you find yourself in a terminal interface well i found an easy fix for that.
i hope it works for you not saying it will though im new to the linux world only just coming out of windows and i dont know much anyways just log on the terminal and use command "sudo dpkg-reconfigure xserver-xorg" then run nvidia-xconfig command reboot and you should be fine only wish this would work for ubuntu 10.10

I just upgraded from 9.10 to 10.4. I am having the following problem:
When I attempt to switch from the user that I am currently logged into, to another user who is also logged in, I get a black screen.
To elaborate, here is the exact sequence of events:
Code:
- Boot ubuntu and login to user A
- Then Click on power menu (top right corner) and select: Switch from A
- I get the login screen
- I select user B and enter my password
[Code].....
I did try to change my session (at the login screen) to gnome-failsafe, xterm, even kde, but still I get the black screen.

I have tried the tips, and to the best of my ability understand the later posts from the sticky post "Graphics Resolution" however I seem to keep reverting back to the blank screen. I did this:
Quote: ATI TIPS: Note that some ATI cards need flgrlx and some do not... If not then this workaround sometimes works: (Found this in another thread / credit to Quote: Originally Posted by surgus View Post

1. When the boot hangs, press ctrl+alt+f1.
2. Login as user with root privileges.
3. Type "cd /usr/share/ati" and press enter.
4. Type "sudo sh ./fglrx-uninstall.sh" and press enter.
5. Type "sudo reboot".
The above only works for some but not all, depending on what card you have and whether it actually is supported by additional drivers (proprietary). All at the moment, mostl seem to need "nomodeset radeon mode=X", where x= 0 or 1... Some ATI cards are not working with the current natty kernel, but are working with the older 2.6.37 kernel or the proposed 2.6,38.9 kerne (please see post 2)l Sometimes (rarely) it'll work but more often it won't, and in the two times it's worked I haven't known how to get it to remember the setting permanently- keep in mind I have no idea what that last paragraph about x= 0 or 1 means.

When I mount Debian 8 live into VMWare Player 7.1.2 64bit, it works awesome with and without graphics acceleration enabled i.e I can get into the desktop and all that.
But, when I installed it, the reboot is just a blank screen. I am not sure how I can proceed from now.
I am on Windows 7, 64bit Ultimate.
