when ever someone uses the log off option it always brings up a black screen that is only fixable by a hard reset. however when switch from or selecting a name to switch to works fine with no errors. is there anyway to fix this? im using lucid 10.04
View 4 Repliesi block my screen (glmatriz screensaver), and go sleep or lunch, and when i get back, i have to logon again, and all my applications have been killed. the weirdest thing is that this does not happen everytime, but i cannot find a pattern to the times that happens.i pretty sure that the machine is not rebooting, cause my uptime still intact.some data: ubuntu lucid (upgraded from jaunty) x86, system all up to date. hardware is a desktop dell vostro 220n (intel chipset, 2gb memory and a pentium e5400.

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.

After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

When the screen is idle for a long time, more than 1 hour, I get a black screen with the mouse arrow but nothing else. the mouse moves the cursor and Ctl+Alt+F1 does work. How to fix this problem?
View 4 Replies View RelatedI installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.
I have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.

I'm trying to test out using xubuntu 10.04 on my one computer and keep getting a black/blank screen after selecting the 'try' menu option.Is there a way to fix this?I have tried some of settings via F6 with no luck.
FYI -The CD works fine as I have tested it on other machines.The version I am trying is xubuntu x86 (although I have tried ubuntu 10.04 x86 with similar results).I can Alt+Ctrl+F1 fine and get to the cmd prompt
This obnoxious bar has just appeared in Smplayer at the top of the screen. It stays there even when I go full screen. Now full screen isn't full screen and there are black edges on both sides of the screen. I have not be able to figure out how to hide it. I do not need or want this onscreen display. How can I configure Smplayer to make this go away? How can I get my 16:9 full screen aspect ratio back? I have done nothing to mplayer or smplayer as far as editing any or changing any configuration files. I tried several videos and it displays on all of them. It was not there last time I used Smplayer.
View 9 Replies View RelatedI have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.

I tried this on two computers with the same results.
I'd previously tried with Ubuntu and had a similar issue, it would go to a purple (if I remember correctly) Ubuntu screen and it sat that forever.
OpenSuse 11.3 with nVidia drivers.I have the screen working fine though it only runs in 1600x1200@75 using the nVidia driver (GTX260 card).When I play a game in full screen mode all seems OK but when I exit the game then I just get the mouse pointer on a black screen.There must be something present since the cursor changes as I move it, normal pointer -> hand over a link etc. It's just that black on black isn't very readable.

View 4 Replies View RelatedI just went out and bought a 19" flat screen LCD monitor. Plugged it in and it is not working correctly. When I start the computer the bios info will show up on the screen, then it goes to the screen that let's you choose an O/S if you were to dual boot. After clicking "enter" it will show the first line of the boot then it goes off into horizontal colors then goes black.

View 9 Replies View RelatedThis problem started within the last few minutes. I run a program in my browser that uploads data from my machine (ubuntu) to another machine (Fedora 13), for manipulation and then spits back the data that does not match our standardised information.
When I tried to run it a few minutes ago, it seemed to take a long time to make the connection. I went back and checked the machine, everything was connected and fine. I decided to reboot the machine from within KDE and then try again. Same result. I went to the machine again and tried to login through KDE, the screen goes black for a few seconds and then returns me to the login screen. I switched over to a virtual terminal and was able to login using the same credentials. I checked the .xsessions-errors file and this is what I am seeing:

I've been a happy Arch Linux user for years now. Recently, on my eee 1000he (an Atom netbook with intel GMA graphics) I've been seeing strange things. After it has been on for some time (usually hours), the screen starts to jitter, just for a fraction of a second, every now and then. After this has happened some times, the screen goes black (one time it went red). The backlight is still on and I can still ssh to the machine which reacts normal appart from the black screen. I can only regain the screen when rebooting. What could this mean? Is it hardware or software? X logs don't shown anything weird, where should I look? I haven't found anyone with the same problem on the net.
View 4 Replies View RelatedI have a few machines set up and running Red Hat 4.1.2-42 in a computer lab. I also have a single test machine running the same version. The machines in the lab work flawlessly.However, when machines are on the login screen, they don't go into power saving mode. That is, after a certain amount of inactivity, the idle login screen should be replaced by a black power saving screen. But this does not happen. The monitor should go into standby (the little green light becomes orange, and the whole screen shuts down until you move your mouse again...you know the drill).I know this is supposed to be the case because this works on the test machine. It just doesn't work in the lab. I think it has something to do with gdm, but I can't for the life of me figure it out.

When I use seperate x screen with nvidia, I only get a black screen on the tv. I can only see the mouse cursor on the tv. But can I see the rest? I use the Nvidia driver. I use the configuration "seperate x screen", and it is connected with a hdmi cable. I use Sabayon linux 5.2, and use the gnome desktop. Could it be that gnome dosn't support seperate x screen like KDE 4?
View 3 Replies View RelatedI work for a public school and we are implementing a number of Ubuntu NBR 9.1 netbooks. I wanted to use Likewise Active Directory for authentication, but have problems with the software so now I'm onto another solution for our problem.
We are going to have one login for all users (Students, is the name). The problem with this is that Website passwords can inadvertantly be stored, potentially compromising users personal data. Additionally, I don't want to have any files left in the Students profile in case people accidentally save personal information in their files.I'm thinking there are potentially two solutions:
1. The Students profile is deleted when the user logs off. This will erase web history and files
2. The Students account is always logged in with a temporary profile (or no profile, if that is possible) that deletes itself at logoff because it is temporary.
I'm having a hard time coming up with search terms for a solution like this, so I thought I would put the question to the experts.
