I am having a funky issue at login. When I enter my username/password at login with the GUI (I disabled the list of users some time ago) the screen will flicker then return me to the login screen. There is no notification of an error. It doesn't matter if I try the recovery console or safe mode there is the same issue when I try and login with this user. However, I can login with a different user open a console and su to that user that wouldn't login at the GUI.
I can't log into my normal user account anymore, though I can log in with root without any problem. When I enter my normal user name and password, the screen blinks, a black page appears and after a couple of seconds I get the login screen again. I deleted /tmp files but no changes. I tried to login using command mode. So I hit Ctrl-Alt-F1 and log into root in command mode, then ran init3, then switched user to my normal user and ran startx. It worked and I logged into my normal account, but I can not do this process every time. So, what is the problem? How can I solve this problem? I used to work with my normal user flawlessly. I installed a bunch of software and also copied some folders to my home directory, but I don't know whether these activities caused the problem or not. I'm using KDE4 under openSUSE 11.2.
I have downloaded the ver10.04. I am running it on my laptop with a NVIDIA GeForce GO 7600 128MB graphics card. I am using the NVIDIA driver on the system. The screen flickers randomly after say every 1 min. By flickering I mean it just refreshes and goes blank for say 1ms during the refresh. It happens even more if I turn on CompViz option.
I've tried both the x86 and x64 versions of Ubuntu 10.04 and installed the current Nvidia hardware drivers on both. Everything works fine until I enable SLI with the --sli=AFR or --sli=OnOnce SLI is enabled there is extreme flickering relating to anything graphical.Including Compiz effects and any opengl software.Disabling SLI returns the compy back to it's good self.I would love to utilize SLI, however can't seem to find a solution for this bug.
All is in the thread title. When I log back in after suspend or hibernate I get a lot of flickering on the screen. I noticed (I think) that it calms down a bit when streaming video from the net, if that gives any clue...
I'm using a dual boot with Vista basic/lucid lynx on an Acer Aspire 5100 laptop.
I'm getting the occasional full-screen black flicker on my laptop, it's an Asus G73JW with an nVidia 460M card, running the restricted drivers. I've installed Gnome3, and so far like it more than Unity, but the flickering needs to stop
I've also noticed that some animations aren't as smooth as they should be, like when I hit the top-left corner to bring up the dock it studders just a wee bit.
openSUSE 11.3 KDE There is a frequent flicker on my screen. Some application OR notification just pops and disappears( giving an impression of a flicker ). How do i find out which application OR notification is it.
I have LucidLynx installed on my eeepc 1005PE. I am currently using it under the gnome interface but i also have the notebook version of it installed (probably because i got a notebook remix of it, not quite sure). All is well except for the following: after i power up my notebook, login and i can see the panel i plug the power cord in. And the my screen starts flickering in orangeblack colors. Nothing i do seems to take it out of this state but a good old hard-reboot.
I was on earlier 9.x version of ubuntu with following configuration working perfectly: IBM ThinkPad T60 with ATI Technologies Inc Radeon Mobility X1400 VGA graphics card (found it from lspci) With an external Dell 19" monitor attached to it. I upgraded yesterday to Ubuntu 10.4 LTS and now the Dell monitor screen keeps flickering all the time! I always work with an external bigger monitor attached to my laptop as working for long hours on the smaller screen of the laptop gives me headache. The frustrating point is, this setting was working perfectly until I was on Ubuntu 9.x, I upgraded to 10.04 LTS and this has stopped working.
Screen flicker Ubuntu 10.10 After installing Ubuntu (Version 10.10 DVD �amd 64Ubuntu 10.10 live DVD). On the following hardware Gigabyte GA-K8VT800-RH motherboard 3GB ram AMD Sempron 3400 cpu. ATI Radeon X1600 Pro Video card. 256M ddr2 AGP VGA/TV0/DV1-1 p/no 882c85-03
The screen resolution looked very good with all screen resolutions working well The colours and fonts very clear. All other device drivers worked 100%. But unfortunately the display flashes about every 10 seconds and the partial beak up of the display only lasts a fraction of a second and very distracting and is unusable. Testing with Ubuntu 10.10 live DVD. With this months Linux Format Magazine also exhibits this problem. However deleting the partition and installing Ubuntu 10.04 Beta1 DVD -386. And all updates downloaded. Works 100% with no screen flicker.
My G73JW works really great except for 1 thing. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat).
I don't what happened but yesterday I was working normally and then I shutdown the computer, today when I opened ubuntu it took me to tyy1 login screen, I entered my username and password then it took me to the normal login screen with the login drums sound and it wrote on my account (logged in) so I clicked it and I entered my password again and then I got to my ubuntu so what went wrong and how to fix it also I noticed that a new terminal in system tools occurred called Kernel (I didn't add it)
I'm using ubuntu 10.10 on Dell inspiron 1520 with Nvidia 8600GT and 3GB RAM
Important: this happened after update to generic-headers-24
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
i am fairly new to Ubuntu. i was using it fine for a month, but today, when i booted my computer up, it came up with a black screen instead of the normal purple ubuntu screen. the black screen had white text on it, and asked for my username and password. from there, it was a terminal prompt. i have been google searching for a while, and have tried typing "startx", "sudo apt-get install ubuntu-desktop", "sudo gdm", and i have also tryed uninstalling xorg, and reinstalling, and none of these things wanted to do anything for me.
This morning I ran sectool (in terminal for the first time. Before that I used sectool-gui) and I got this (written to file)...
See attachment please..
I think... the user "Jetty" may be a part of (or has something to do with SQL?).. This machine I have is not a server (in fact I know pretty much nothing about web servers).. this machine is used purely for local app development (python PyQt4/ and C++/wx - making games, general utilities, specialized calculators...etc)
So... Can anyone please tell me who the user "Jetty" is ? (The others are safe, I compiled python/SIP/PyQt4/wx/aliens from source... so that;s probably why it doesn't belong to packages.
Plus, My screen started to flicker some time (could it be possible someone is messing w/ my xorg configs?)
Seems that I have been having a problem with the initial user login on Ubuntu 10.10 Netbook. Whenever I try and login the normal way (from standard gui login) my system comes to a standstill and I have to switch to command line (ctrl+alt+F2) and restart/shutdown my computer in that fashion. The only way that I can login and actually see my desktop without any hint of my system freezing up is by booting into the ubuntu recovery Console using the dpkg function to remove any broken packages, select boot normally (where I have to login through the command line), and manually startx.
Originally I was running an x64 version of ubuntu desktop 10.10 but I switched to an x86 version of netbook due to many incompatibilities in software and trouble finding x64 software for my system. When I was on Ubuntu Desktop I had a similar problem where it would freeze at login as well but I fixed it by removing compiz & compiz-core. I tried that with this version of the OS but had no luck because it said that compiz was not installed.
Not a major issue, just somewhat annoying that I have to resort to other means to login
PS: My computer is a Toshiba P500-026. Some stats are listed below in my signature if its relevant to my problem.
I've just installed Ubuntu 10.4 alongside Windows. During the installation process, everything was black, then it flickered for a couple of seconds, then went black again. This happened many times. After the installation, I was hoping it would stop, but the same thing happens at the login screen. It flickers for a couple of seconds, then goes black. I figure it has something to do with my display drivers, but I don't know how to install them without using Ubuntu. If it makes any difference, I have an ATI Radeon 4890 video card.
I was under the impression the Linux (in my case the Fedora OS) is very secure. However I've learnt with deep concern that that one can have access to the system during system startup i.e one can give various startup directives and bypass the normal login UI to have direct root access.
Is there a way to disble this so that the directives during startup are fixed and cannot be altered. I would like to make the system secure to the maximum extent possible.
The problem come after i kill the Xorg using the kill command,and the screen turns to black without anything so that i can do nothing. The problem goes on after reboot
I have installed VirtualBox and setup a Windows Vista host, initially with a .vdi of 10gb. That filled up quickly, so I added another 20gb secondary partition, after first trying to allocate a .vdi to a SCSI controller. Configured the drive in Windows (Computer Management), and all seemed ok. I shutdown VB, and rebooted my Linux host (openSuse 11.3). Now I keep bouncing back to the login screen, and can't login to Linux KDE, but can login to a console.I do have the following info:
I did see a message before, that I don't see anymore, that said it could not start NFS services due to missing entry in fstab. Another I'm seeing now is it couldn't start the avahi-daemon, no space left on device. This is odd, since I have a 200GB drive, with half of it left, only max 30GB set to VB. Here's my df -k output:
/dev/sda6 Use% is 100% devtmpfs Use% is 1% tmpfs Use% is 1% /dev/sda7 Use% is 46%
So root "/" is mounted on /dev/sda6, which looks like it could be a problem, but why would this suddenly be a problem after working with VirtualBox? Could this be a matter of just freeing up space on /dev/sda6? Like the /tmp folder that's under "/"?
i have to reinstall my pc with a testing version. The installation almost is the same as stable version (lenny). But, the problem is that, i can't login it after the installation completed. The new user i created during installation is invalid! So, i have to enter the single user mode, to my surprise, the new user(i created before) doesn't exist! So, i add a user here.But, i still can't login to my system as the normal mode.How should i resolve such a problem?
Is it possible to have multiple passwords on the same account, where one password allows only normal login and another only when accessing the machine remotely (for example, via ssh)?
I am unable to login as normal user. I am sure that my password is correct. What are the possible reasons behind this and also the solutions. My /etc/password and /etc/shadow files are good and my login haven't set to /etc/nologin.
Actually this a question asked to me by a Novell(Suse Enterprise Linux) Regional manager.
I have a desktop running Hardy and till friday it was running good. Today is monday and I guess it has got monday blues like I get every monday at work.Today I tried to start it as usual but it just refused to go further than login screen. I just can not login. It just hangs it there. I do not know what has gone wrong. I did not change anything since friday and no one else uses it. Theres nothing in logs that could give any idea. It just hangs without any reason and is still on the login screen for ever. It does ask my username and password but then it does not go further.But to my surprise I tried logging in with root and it gave me expected error that system administrator is not allowed to login from gnome.
I just finished installing 10.4 on my Dell Latitude X300, and it will only run in low-graphics mode. I will try to boot like normal, but then a blank screen. I have to boot in Recovery Mode and use the Failsafe graphics option.
