Ubuntu Installation :: Getting Black Screen When Switching Users In Lucid 10.4?
May 3, 2010
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.
Lucid is not in testing but it's released.It seems it works now, with all desktop effects activated and switching users and closing sessions.The only thing I still don't know is which screensaver can I use if removing gnome-screensaver?
I just upgraded to Lucid Lynx, and like most people, I'm getting the black screen during boot. So, I went into the grub edit screen, and I tried every variation of the nomodeset fix I could find. So far, nothing has worked. I don't know what graphics card I have, but it's always given me problems.
my mother woke up and came in here to get online and when I hit her name on the sign in screen its just stuck with her name on the screen So she woke up me and I hit CANCEL SIGN IN and now its stuck on CANCELING..... And its been like that for 10 min I am too scared to do ctrl alt backspace because its going to log me off of everything
I cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.
I get a black screen (with tiny bits of white on opposite corners of the screen) every time after logging into Kubuntu Lucid AMD64. The only thing I can do is move my mouse pointer over that black screen which doesn't go away. I booted into recovery mode and with command prompt typed "startx" to start graphical mode. That resulted in the same black screen. Then I decided to reboot and install Fluxbox via the command prompt under recovery mode. Now, I'm able to view graphically under Fluxbox after selecting it over the default KDE and logging in. But how do I get regular KDE/Kubuntu to work again? I don't know what happened to make it stop working!
So I've been using Ubuntu for about a month now. Everything is great and all but today when I booted into Ubuntu everything was going well--the splash screen appeared and the dots were doing their thing and all--but then there was just a blank screen. Some people have had this problem after a fresh install of Lucid, but its been working for a while so I don't get why it isn't working... I didn't do anything to the system except run some updates before I turned off the computer.
Yesterday, 9/1/2010, I received a bunch of patch updates for 10.04 (64-bit) and applied them to my laptop (Dell Latitude E6510, Intel Core i5). After they applied, it asked me if I wanted to reboot now or later. I chose later to finish my work and then shut my laptop off. This morning, I turned it on, only to get a black screen during bootup and also during login. I know it's working behind the scenes because I can hear the drum sound when it's ready to login and I can still press the power button and hit enter to shut it down. I tried using Alt+F2->F12 but it would only show a black screen.
My temporary workaround was to hold the shift button during startup to get the grub menu and then select the older 2.6.32-23 kernel to bootup instead of the newer 2.6.32-24. I am able to boot ok in the older kernel and it's working fine, but I don't know what is causing the problem for the newer one and cannot boot into that one.
I believe I was running 2.6.32-24 fine up until I received a bundle of patches to apply to my system. So the question is, is there a way to figure out what patches were applied in yesterday's bundle so I can back them out? If not, how can I fix this so I can run the newer updated kernel?
I recently upgraded from 9.10 to 10.04 and was having trouble getting 3D graphics enabled on my ATI card. I am running on an MacPro3,1I read through this guide as I was having errors regarding fglrx so I uninstalled it and as instructed issued the following:
I have a Logitech Quickcam Chat webcam (USB ID 046d:092c) that's worked with my Ubuntu with minimal problems (just some nVidia driver crap) for ages now. I'm not using nVidia anymore (Intel now), but since my fresh install of Lucid, my webcam doesn't seem to capture anything. It is detected by lsusb, but when I open Cheese, the picture is just black. Skype doesn't give me any video at all, not even that annoying static or green lines. Clicking the Test button in my Skype Options undedoesn't do anything;double-clicking it gives me a full-screen grey screen - pressing Escape takes me back to the preferences window. After I get the grey full screen and press Escape, the Test button is gone until I close the Options window and open it up again.Going into gstreamer-properties and testing v4l2 (under Video -> Default Input) just shows me the 'Testing ... Click Ok to finish' window for ages until I close it - no video appears or anything and I'm not entirely sure what I'm supposed to be seeing. Testing with the 'Test Input' option does give me the coloured lines and static. Testing v4l seems to make it crash, but no error comes up in the terminal I'm running it from.lsusb output:
Code: Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 002: ID 046d:092c Logitech, Inc. QuickCam Chat
im using Ubuntu 10.04 and whenever i enable it and try to iniate it it just makes my screen black =/. It sucks because i really loved that feature (on 64-bit btw)
The new NVIDIA drivers don't seem to work as seamlessly as back in Jaunty and before. In Lucid when I activated the drivers I had to do some grub tweaks to make my splash look normal... But with Maverick it is even more messed up...
Problem: The splash either doesn't appear at all (black screen) or it appears in the text format rather than graphics... In some instances it even hopelessly tried to load the graphics splash - loaded the background but the instead of Ubuntu logo and the progress-bar animation it displayed a "Ubuntu 10.10" in a monospace font.
I can't seem to get Ubuntu to run on my old Dell Dimension 2300. It boots to a purple screen then it goes to a black screen with a load of writing nothing else happens after this screen. [URL] Could someone advise how I can get it to work?
After installation, I had no problems using wireless. Next, I added a new user (with administrative access). Now, when I log in as the new user, nm-applet doesn't appear in the panel and there is no wireless access. I've tried adding the Notification Area (nothing appears), making sure that the new user can connect to networks, etc with no success. System Monitor shows that nm-applet is sleeping. When I restart and login as myself, everything is still working fine. Computer: Computer: Dell Latitude D600

What additional info should I provide to assist diagnosis?
'm trying to duel boot windows 7 and ubuntu 11.04 on an Acer Aspire 5736, but when I try to boot from the cd (which I burned with InfraRecorder) it first goes to a black screen with a blinking under score in the corner, then to a purple screen with a couple symbols at the bottom, and then the screen goes black and nothing else ever happens
After succesfully installing Ubuntu 10.4 x32 and rebooting pc hangs on black screen with a flashing white dot in the top left corner of my screen, i've tried installing it twice with the same results.
my setup is: Asus p5q-e, 4 gig of corsair dual ram, ati 4850 graphics, onboard audio. ahci mode win 7 installed on intel ssd, and xp on a samsung 320 gb sata 2, i had this configuration running fine for 2 months without boot loaders, on pc start up i choose from which hdd to boot from.
i installed ubuntu on the samsung drive where it was recognised fine, wiped it all and installed automatically.
pls let me know if there is anything i missed, and advice if possible in what to do.
I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.
another post about this. I just don't know how to handle this, as I'm pretty nsee the grub loading menu, but screen just freezes after, no way I can reboot, or open a console. In recovery mode I can log as root in console, though.I run Debian 6, 64 bits. I have an intel q6600 and a nvidia geforce 9800GX2.
I have POPFile in my startup applications. I know how to automatically kill it when login out but cannot find a way to kill it if I just switch users (other than manually stopping it). It's important to kill it when using the switch users function because the new user will have access to the old user's POPFile database, have access to his email, etc, if I do not.I have a "lynx -dump http://127.0.0.1:8080/shutdown &>/dev/null" line in my /etc/gdm/PostSession/Default file that shuts down POPFile at log out. I need to do the same or something similar when switching user. Is there a way?
Since upgrading from 9.10 to 10.04, the "Switch User" functionality no longer works. I had hoped that upgrading to 10.10 might resolve the issue, but no joy. I am using 32bit Ubuntu 10.10 on a Levono R51 laptop, with three users. 9.10 was installed from a LiveCD, and I have partitioned the hard drive so that OS is in the first partition, and the three home directories are in the second partition (just in case I need to do a complete re-installation from LiveCD). Most of time only one person uses the laptop, but if a second person tries to switch from the current session and log in, they are greeted with the following;
-- a black horizontal line (approx top quarter of the screen) -- a purple background with the Ubuntu title and 5 red dots (lower 3/4 of screen) -- but no login screen -- moving the mouse renders a white box (approx 1x1 inches) with some black marks
The original user can recover their session with Ctrl-Alt-F7, but this essentially makes the laptop only usable for one person (one active login) unless the original user logs off.
I have been experiencing issues when switching users since my last update; I filed a bug, but I was interested if anybody else was having the same problem:URL...In a nutshell the computer freezes temporarily during the switch user process. The longer it is running, the longer the freeze lasts. When frozen the screen is black except for a mouse pointer; but the mouse and keyboard are not responsive including the usual X command keys (Ctrl-Alt-Del, Ctrl-Alt-Bksp, Ctrl-Alt-F1, etc.).When I get the chance I am going to rollback gdm to see if that makes a difference.
I want to execute a bash script that switches user and then executes a series of commands. None of this users have root privileges. I guess I have to edit the sudoers file to give user1 (the user executing the script) privileges to be able to log as user2 with no password prompt. I've been looking for this example but I haven't found any.
I have an external USB drive that is NTFS. It mounts fine under my account and my wife's, but only if I fully shut-down the computer between switching. While switching users or logging out then in with a different account it will not mount the drive. I am not sure what to do... but we both access data from the same drive.
User switching doesn't work for me anymore since upgrading to Lucid. When I choose "Switch From <user>..." in the logout menu on the top-right of my screen, it jumps to the login screen (gdm) but it doesn't show any usernames as it should.I wish I could get a screenshot of gdm but I'm not sure how.
I'm facing an odd issue with my Ubuntu 10.04. So, I have WLAN activated and working on my user account. Then I switch to another account on the same computer and nm-applet tray icon disappears! I have activated the option that all users may use the WLAN connection, but the tray-icon doesn't show up for other users. Only the one who logs in first sees it. Network connection is working properly, but the tray icon would be handy.
Trying to start nm-applet manually in terminal results in an error saying that nm-applet is already running (sure it is, on the first account that logged in). But is it possible to have the tray icon visible for all users?
Problem-PC automatically boots into a black screen with blinking cursor. No message or nothing
I have 4 HD. Primary drive has Windows Vista, Secondary no OS installed. Sata1 HD Ubuntu 10.04, Sata2 Windows 7. Prior to installing windows 7 all was perfect but once I did it, grub got all screwed up. The only way I can boot into grub is if I manually select my Sata1 which has Ubuntu on it and only then it allows me to select Linux or Windows OS. How can I change that so it can boot up normally as before? I'm assuming that grub was installed in the primary drive which has vista on it, but once I installed windows 7 it got deleted and when I tried reinstalling Ubuntu, the grub was not installed in the primary drive.
I have spent the better part of 2 days perusing these forums for assistance. Here is the short story:I run a 7 year old custom build with a 82865G Intel Chipset and a NVIDIA FX5200 graphics card. Had been running a sluggish XP and after adding 2GB of fresh RAM wished to start fresh with my old friend, Ubuntu.
I've tried 10.04 LTS with and without my NVIDIA card installed with no luck. I have successfully installed 10.04 using the alternate install, but this also goes to black. I can hold shift to see GRUB and play around there, but no luck so far. I've also tried 9.10 but have not gotten past the pulsing Ubuntu image. I've seen plenty of support for NVDIA and Intel onboard graphics chips suggesting boot commands like nomodeset and i9015.modeset=0/1...it's all falling short.
I'm heavily leaning towards just installing an earlier LTS or a different linux distro all together. If there no one can help me debug, maybe someone can suggest a distro that will make me happy.
I've installed ubuntu 10.04 onto my Dell Latitude e6510 (through the wubi installer), but I can't get anything except a black screen. I'm pretty new to ubuntu, but after a bit of looking around at graphics issues I found a bunch of boot parameters and tried different combinations of them. i915.modeset=0 Gave me the purple loading screen, until the screen went black and I got flashing caps lock and scroll lock lights.xforcevesa gave me a completely black screen -- not receiving power at all
I also tried noapci, acpi=off, irqpoll, and pci=routeirq as parameters. None of those had any success.I've also tried letting ubuntu boot with a black screen until I heard the African drums and pressing Ctrl+Alt+F1 to go into the console, but the screen stayed black then as well.
I have downloaded Last version of Ubuntu 11.04 and installed it. The installation went correctly with some flickering in display during installation. But the real problem starts after installation, when I turn on my PC and select Ubuntu from GRUB, the screen flickered a lot and then went black and PC got hanged.
